Definitions

  • the invention relates to a conductor connecting terminal with an insulating material housing and with a spring-loaded terminal connection, which has a contact body formed from a sheet metal element with a bottom section, side wall sections protruding from and spaced apart from one another, and solder connection contact tongues, the solder connection contact tongues being bent out of the plane of the bottom section , span a solder connection level that is offset from the level of the base section and form an indented area of the base section.
  • the bottom section forms with the side wall sections a conductor receiving channel for receiving an electrical conductor.
  • At least one leaf spring tongue protrudes from the side wall sections and has a clamping edge for clamping an electrical conductor received in the conductor receiving channel.
  • the front of the insulating housing has a conductor entry opening leading to the conductor receiving channel.
  • the invention further relates to a set of such a conductor terminal and an operating tool.
  • Such conductor connection terminals are made, for example, with a pusher integrated in the insulating material housing DE 10 2010 014 144 B4 known.
  • WO 2013/176859 A1 discloses an SMD PCB terminal with from Actuating slides protruding from the top of the insulating material housing for opening a clamping point formed on the respective spring-loaded terminal connection for connecting an electrical conductor;
  • KR 10 2014 0122904 A describes a similar SMD PCB terminal block with a spring-cage terminal connection with two mutually facing leaf springs, which have actuation tabs pointing in the direction of the conductor insertion, as well as an insulating material housing with an actuation slide that can be slid into an opening in the top and rear.
  • solder connection contact tongues By bending the solder connection contact tongues out of the plane of the base section in such a way that they become one Clamp the level of the bottom section of the staggered solder connection level, reducing the height of an electrical circuit board provided with the conductor connection terminal.
  • the conductor connection terminals can be hooked into an opening in the circuit board and soldered to the back of the circuit board.
  • the conductor terminal is therefore not simply placed on a circuit board and soldered to the top with solder connection contacts.
  • This offset of planes also forms an indented area of the contact body, into which a closure cover can be snapped. This cover provides a suction surface for an automatic assembly machine for handling the conductor connection terminal.
  • a light trap or dark spots form if there are light elements (for example light-emitting diodes LEDs) on the circuit board on the side of the solder connection contacts.
  • light elements for example light-emitting diodes LEDs
  • the depressions within the conductor connection terminal can be perceived as "dark spots" by a scattering shard.
  • the perceptibility of the conductor connecting terminal arranged adjacent to lighting elements is reduced with a sealing cover.
  • the sealing cover forms a separate part from the insulating material housing, which is connected to the contact body and also functions without the insulating material housing.
  • the sealing cover can have latching lugs which are adapted for latching into latching openings in the contact body.
  • the closure cover has latching openings or latching edges which are adapted for latching with latching lugs of the contact body.
  • This latching of the closure cover with the contact body avoids latching openings on the insulating housing, which could reduce the air and creepage distances.
  • the closure cover can have fingers protruding perpendicularly from a cover plate of the closure cover. A pair of such fingers is then arranged opposite one another at a distance from one another and is adapted for immersion in the indented area for abutment, in each case adjacent to a connecting web of the contact body that leads from the bottom section to a soldering contact tongue. In this way, the closure cover is snapped into place with a pair of such opposing fingers on mutually opposite connecting webs with locking elements of a pair of such fingers pointing away from one another. While the cover plate remains above the level spanned by the solder connection contact tongues, the fingers dip into the indented area of the contact body.
  • the fingers can each have a recess with a locking edge.
  • the troughs are then each designed to receive a latching lug of the contact body. Such a catch can protrude from a connecting web, for example.
  • the locking edge is formed by a boundary wall of the trough.
  • the side walls that delimit the trough increase the resistance of the finger to elastic deformation when subjected to force and bending stress.
  • the fingers can also each have a locking lug, which is designed to snap into a locking opening of an adjacent connecting web of the contact body.
  • Cover tongues of the cover plate can protrude on the level of the cover plate between two fingers of the closure cover arranged next to one another.
  • the cover tabs can be slotted through by the fingers Sections of the cover plate are free. The slots improve the air and creepage distances, especially when the insulating housing is immersed in these slots.
  • the cover section of the insulating material housing opposite the bottom section can be completely closed on the side of the spring-loaded terminal connection facing away from the bottom section in the area adjacent to the side wall sections and the at least one leaf spring tongue of the contact body.
  • the insulating material housing on the rear side, which lies opposite the conductor insertion opening, can have an actuation opening that leads to actuation tabs of the at least one leaf spring tongue.
  • the actuation opening is bounded by the cover section of the insulating material housing, forming a guide channel.
  • the cover section which adjoins the at least one actuating tab above the spring of the spring-loaded terminal connection, thus represents a guide wall of a guide channel, on which an actuating tool or an actuating tool inserted into the actuating opening or an actuating element which is displaceably installed in the actuating opening is guided.
  • the actuation then takes place exclusively via the actuation opening accessible from the rear, so that the actuation forces only act as shear forces on solder contacts of the conductor connection terminal.
  • the at least one leaf spring tongue can only be opened by an operating force directed in the opposite direction to the conductor insertion direction from the rear actuation opening in the direction of the front conductor insertion opening. A force component that acts from the cover section to the bottom section is avoided, so that the forces acting on soldered joints of the conductor connection terminal do not impair these soldered joints.
  • the guide channel of the actuation opening can be formed not only by the cover section, but also by spaced-apart lateral inner wall sections of the insulating material housing and a base section opposite the cover section.
  • the guide channel is thus delimited on one side, on both sides or possibly on all sides or all around by wall sections.
  • a separate actuating tool is thus optimally guided to the at least one actuating tab.
  • an actuating element can also be installed in such a guide channel, which is then slidably mounted in the actuating direction from the front to the rear.
  • the base portion which delimits the guide channel in the direction of the base portion, can be spaced from the base portion of the spring-loaded terminal connection to form a conductor receiving pocket.
  • a conductor collection pocket is thus provided between the base section and the base section in the conductor insertion direction behind the clamping point formed by the clamping edge of the at least one leaf spring tongue for clamping an electrical conductor.
  • the conductor insertion area or conductor receiving area is delimited by the base section through the actuation plane lying above, into which the respective actuation tab of the at least one leaf spring protrude. This prevents the actuation opening from being blocked by strands of an electrical conductor.
  • the guide channel can end immediately in front of the at least one actuation tab, so that the guide channel is formed by the actuation opening and then merges into the actuation tab of the leaf spring and the cover section lying above it.
  • the actuating opening is thus through the cover section and the two spaced apart actuation tabs continued.
  • An indentation can be provided in the cover section of the insulating material housing in the rear area, which is opposite the conductor insertion opening. This indentation then merges into the actuation opening leading to the actuation tabs.
  • This indentation has the advantage that it provides a positioning area into which an actuating tool is inserted from above, obliquely from the rear or directly from the rear. The actuating tool is then positioned through the lateral boundary walls of the indentation and the bottom of the indentation such that it can be inserted into the actuating opening adjacent to the indentation.
  • the bottom section can have solder connection contacts protruding from the contour of the insulating material housing. These are then intended for soldering onto a printed circuit board and can be SMD contacts for surface solder mounting or pin contacts for push-through solder mounting.
  • the actuation opening can be provided for receiving a separate actuation tool.
  • the actuation opening extends from the back to the front through the insulating material housing and opens out on the front side adjacent to the conductor insertion opening. This can also be used to actuate from the front and / or to check the voltage potential at the spring-loaded terminal connection on the front.
  • an actuating element is slidably received in the actuating opening.
  • the actuating element can have a protruding actuating section which is designed to apply force to the at least one actuating lug to open the clamping point formed by the clamping edges. This protruding actuating section is then located in the interior of the insulating material housing in the area of the actuating tab of the leaf spring tongue.
  • the actuating element can have a head section which is accessible from the rear of the insulating material housing for the application of force and a signal section which projects out of the front side of the insulating material housing when the spring-loaded terminal connection is open. With the help of this signal section it becomes visible whether the clamping point formed on the clamping edge of the leaf spring tongue is open or not.
  • the actuating element can be pushed back into the rest position by applying force to the signal section in the direction of the rear, in which the leaf spring tongue is not impaired by the actuating element and exerts a resilient clamping force on an inserted and to be clamped electrical conductor.
  • the indefinite term “a” is not to be understood as a numerical word. So if e.g. from a spring-cage connection, a leaf spring or a conductor insertion opening or actuation opening, this is to be interpreted in the sense of "at least one”.
  • the insulating material housing can thus also have a plurality of conductor insertion openings arranged next to one another.
  • the conductor connection terminal can have a plurality of spring-cage terminal connections which are accommodated next to one another in the insulating material housing and are assigned to a respective conductor insertion opening and an actuation opening.
  • the invention is further achieved by the set consisting of a conductor connecting terminal and an actuating tool, the actuating tool having a holding section and an actuating finger designed for insertion into the actuating opening and for pushing apart the actuating tabs of the clamping point.
  • a separate actuating tool is provided, which with its at least one actuating finger an associated actuating opening of the insulating material housing can be inserted from the rear, in order then to be guided between the actuating tabs by moving the actuating finger in the direction of the front side of the insulating material housing in order to urge them apart.
  • the holding section and the actuating finger are preferably at an angle to one another. This angle can preferably be in the range of approximately 90 degrees +/- 20 degrees.
  • the holding section and the at least one actuation angle are particularly preferably arranged at right angles to one another.
  • a plurality of actuating fingers arranged next to one another and spaced apart from one another can be provided on the holding section for insertion into an associated actuating opening of a plurality of actuating openings of the insulating material housing of the conductor connection terminal. This makes it possible to open several terminal points of a multi-pole conductor terminal at the same time, which simplifies handling.
  • Figure 1 shows a perspective view of a first embodiment of a conductor terminal 1, which has an insulating housing 2 and a number of spring-loaded terminal connections 3 installed in the insulating housing 2. Of the spring-cage terminal connections 3, outstanding solder connection contacts 4 are visible from the insulating housing 2 on the front and rear.
  • indentations 6 are present in the insulating material housing 2. These indentations 6 merge into actuation openings on the rear, which lead into the interior of the insulating material housing 2.
  • a base base 7a formed as part of the insulating material housing 2 and on the rear side of the indentations 6 there is also a base base 7b formed as part of the insulating material housing 2. This is used for support on a circuit board if the conductor connection terminal 1 is inserted into an opening in a circuit board and is soldered to the solder connection contacts 4 on the back of the circuit board.
  • Figure 2 shows a perspective view of the basic structure of a spring-loaded terminal connection 3 for the circuit board. It becomes clear that the spring-loaded terminal connection 3 is formed in one piece from a sheet metal element as a stamped and bent part.
  • a base section 8 is provided, from which two side wall sections 9, which are spaced apart, protrude.
  • a conductor receiving channel for receiving an electrical conductor is formed by the side wall sections 9 and the bottom section 8.
  • the conductor receiving channel can be at least partially closed at least partially by limiting tabs 10 on the side opposite the base section 8, which are bent toward one another and are bent over by the side wall sections.
  • the top of the conductor receiving channel can also be closed by sections of the insulating housing 2.
  • leaf spring tongues 11 protrude from the side wall sections 9 in the conductor insertion direction L.
  • the leaf spring tongues 11 extend approximately parallel to the base section 8 and extend towards one another.
  • At the ends of the leaf spring tongues 11 each clamping edges 12 for connecting an electrical conductor or its stripped end are formed.
  • an embodiment with only one leaf spring tongue 11 is also conceivable, which, for example, forms a clamping point with a side wall section 9 or a tab protruding therefrom.
  • actuating tabs 13 protrude from the leaf spring tongues 11 at the upper edges, which lie opposite the bottom section 8. These actuation tabs 13 are pointed out at an angle away from one another and are provided for receiving an actuating tool or actuating element. They extend with their free end in the conductor insertion direction L or in the direction of extension of the leaf spring tongues 11 and expand in a funnel shape towards their free end. With the aid of such an actuating tool or actuating element inserted between the actuating tabs 13, the leaf springs 11 are moved away from one another in order to open the clamping point formed on the clamping edges 12 and to be able to remove a clamped-on electrical conductor.
  • the level of the base section 8 in the region of the side wall sections 9 and the leaf spring tongues 11 is raised or offset relative to the level of the solder connection contacts 4, in order in this way to provide an indentation or a free space on the underside of the spring-loaded terminal connection opposite the leaf spring tongues 11 3 form.
  • the conductor insertion plane formed by the conductor insertion channel for inserting an electrical conductor is thus arranged at a relatively large offset from the solder connection plane defined by the solder connection contacts 4.
  • the depth of the indentation or of the free space should at least correspond to the thickness of a conventional printed circuit board, so that the solder connection level on the underside of the PCB and the plug-in level is above the top of the circuit board.
  • Figure 3 omits a sectional side view of conductor terminal 1 Figure 1 detect. It becomes clear that the solder connection contacts 4 on the back of a circuit board 14 are soldered to the latter when the conductor connection terminal 1 is inserted into an opening 15 in the circuit board 14.
  • the base bases 7a, 7b of the insulating material housing 2 are supported on the underside of the printed circuit board 14.
  • the spring-loaded terminal connections 3 are fixed in position on the insulating material housing 2, in that projections 16 of the insulating material housing 2 protrude through associated storage openings 17 of the base section 8.
  • the level of the bottom section 8 in the interior of the insulating material housing 2 is offset in relation to the level formed by the solder connection contacts 4 to the cover section 18 of the insulating material housing 2.
  • the solder connection contacts 4 are thus pulled further down, so as to enable rear mounting on the printed circuit board 14.
  • cover section 18 above the spring-loaded terminal connection 3 in the area of the leaf springs 11 and in particular the actuating tabs 13 is completely closed.
  • the cover section 18 continues to the rear of the insulating material housing 2, which lies opposite the conductor insertion opening 5, so as to limit an actuating opening 19 for inserting an actuating tool 20.
  • the actuation opening 19 is delimited by a base section 21. This base section 21 is arranged at a distance from the bottom section 8 of the spring-loaded terminal connection 3 in order to limit a conductor collecting pocket 22.
  • actuating tabs 13 protrude further from the terminal end 12 in the direction of the plug-in direction L in the direction of the base section 21. If an actuating finger 24 projecting from a holding section 23 of the actuating tool 20 is now inserted into the actuating opening 19, it acts on the actuating tabs 13 lying opposite one another and presses them apart on an actuating plane. This actuation plane lies above the conductor clamping plane, which is formed by the clamping edges 12 and the adjoining conductor catch pocket and which is delimited upwards by the base section 21 towards the actuation opening 19.
  • the clamping point of the spring-loaded terminal connection 3 is thus opened by an actuating force which acts in the direction of arrow B opposite to the direction of insertion of the conductor L.
  • the actuating force B exerts a shear force on the solder connection contacts 4 at best.
  • An actuating force acting transversely to the surface of the printed circuit board 14 is avoided, which could impair the soldering points on the solder connection contacts 4.
  • a housing part in the form of a closure cover 40 is snapped into the indented area of the base section 8 from the underside.
  • projections in the form of locking lugs 56 snap into locking openings in the sheet material of the base section 8.
  • a suction surface for an automatic assembly machine for handling the conductor terminal 1 is provided.
  • a light trap or dark spots form if there are light-emitting elements (for example light-emitting diodes LEDs) on the circuit board 14 on the side of the solder connection contacts 4.
  • the depressions can are perceived as "dark spots" within the conductor connection terminal 1 by a diffusing screen.
  • the closure cover 40 is optional. Without such a sealing cover 40, also the bottom section 8 itself can be used as a suction surface for an automatic assembly machine.
  • Figure 4 omits a perspective rear view of the conductor terminal 1 Figures 1 and 3rd detect. It is clear that the indentations 6 are each delimited by the base section 21 as the bottom surface and opposite inner wall surfaces 25 of the insulating material housing 2. With the help of these indentations, the insertion of the actuating tool 21 into the actuating indentation 19 is facilitated in that the indentation 6 provides a funnel-shaped insertion area.
  • Figure 5 shows a perspective view of the conductor terminal 1 inserted into a circuit board 14. It is clear that the circuit board 14 has a rectangular opening into which the conductor terminal 1 is inserted from the underside. However, the conductor insertion opening 5 opens out at the level of the top of the circuit board 14 or possibly slightly above it. Such an installation allows the overall height of an electrical device to be reduced compared to the simple soldering of a simple conductor connection terminal 1 onto the upper side of the printed circuit board 14.
  • Figure 6 omits a perspective view of the conductor terminal 1 Figure 5 Detect without insulating housing 2.
  • the position of the several spring-loaded terminal connections 3 arranged next to one another is visible in the receiving opening 15 of the printed circuit board 14.
  • actuating tabs 13 each protrude from the leaf springs 11 on the upper side, which is opposite the bottom section 8. These extend from the end regions of the leaf spring tongues 11 with the clamping edges 12 over the clamping edges 12 beyond.
  • a pair of such actuation tabs 13 of a spring-loaded terminal connection 3 are bent with their free ends pointing away from one another in order to form an insertion funnel for the actuation finger 24 of an actuation tool 20.
  • the clamping edges 12 of the leaf springs 11 of a spring force clamping connection 3 are directed towards one another by the spring force of the leaf springs 11.
  • the clamping edges 12 can then rest against one another without a clamped electrical conductor. If an electrical conductor is now guided past the side walls 9 and the leaf springs 11 to the clamping edges 12, then this is clamped to the spring-force clamping connection 3 by the clamping force of the leaf springs.
  • Figure 7 leaves the arrangement open Figure 6 Detect with printed circuit board 14 and spring-loaded terminal connections 3 inserted therein into a receiving opening.
  • the actuating tool 20 is now inserted into the front, right spring force terminal connection in such a way that the actuating finger 24 is placed between the actuating tabs 13.

Description

Die Erfindung betrifft eine Leiteranschlussklemme mit einem Isolierstoffgehäuse und mit einem Federkraftklemmanschluss, der einen aus einem Blechelement geformten Kontaktkörper mit einem Bodenabschnitt, von dem Bodenabschnitt abragenden und voneinander beabstandeten Seitenwandabschnitten und Lötanschluss-Kontaktzungen hat, wobei die Lötanschluss-Kontaktzungen aus der Ebene des Bodenabschnitts herausgebogen sind, eine zur Ebene des Bodenabschnitts versetzt angeordnete Lötanschlussebene aufspannen und einen eingebuchteten Bereich des Bodenabschnitts bilden. Der Bodenabschnitt bildet mit den Seitenwandabschnitten einen Leiteraufnahmekanal zur Aufnahme eines elektrischen Leiters. Von den Seitenwandabschnitten ragt zumindest eine Blattfederzunge ab, die eine Klemmkante zum Anklemmen eines in den Leiteraufnahmekanal aufgenommenen elektrischen Leiters hat. Das Isolierstoffgehäuse hat frontseitig eine zu dem Leiteraufnahmekanal führende Leitereinführungsöffnung.The invention relates to a conductor connecting terminal with an insulating material housing and with a spring-loaded terminal connection, which has a contact body formed from a sheet metal element with a bottom section, side wall sections protruding from and spaced apart from one another, and solder connection contact tongues, the solder connection contact tongues being bent out of the plane of the bottom section , span a solder connection level that is offset from the level of the base section and form an indented area of the base section. The bottom section forms with the side wall sections a conductor receiving channel for receiving an electrical conductor. At least one leaf spring tongue protrudes from the side wall sections and has a clamping edge for clamping an electrical conductor received in the conductor receiving channel. The front of the insulating housing has a conductor entry opening leading to the conductor receiving channel.

Die Erfindung betrifft weiterhin ein Set aus einer solchen Leiteranschlussklemme und einem Betätigungswerkzeug.The invention further relates to a set of such a conductor terminal and an operating tool.

Derartige Leiteranschlussklemmen sind beispielsweise mit einem in das Isolierstoffgehäuse integrierten Drücker aus DE 10 2010 014 144 B4 bekannt.Such conductor connection terminals are made, for example, with a pusher integrated in the insulating material housing DE 10 2010 014 144 B4 known.

WO 2013/176859 A1 offenbart eine SMD-Leiterplattenklemme mit aus der Oberseite des Isolierstoffgehäuses herausragenden Betätigungsschiebern zum Öffnen einer an dem jeweiligen Federkraftklemmanschluss gebildeten Klemmstelle zum Anklemmen eines elektrischen Leiters; WO 2013/176859 A1 discloses an SMD PCB terminal with from Actuating slides protruding from the top of the insulating material housing for opening a clamping point formed on the respective spring-loaded terminal connection for connecting an electrical conductor;

KR 10 2014 0122904 A beschreibt eine ähnliche SMD-Leiterplattenklemme mit einem Federkraftklemmanschluss mit zwei aufeinander zuweisenden Blattfedern, die in Leitereinsteckrichtung weisende Betätigungslaschen haben, sowie ein Isolierstoffgehäuse mit einem verschiebbar von in eine Öffnung der Ober- und Rückseite eingesetzten Betätigungsschieber. KR 10 2014 0122904 A describes a similar SMD PCB terminal block with a spring-cage terminal connection with two mutually facing leaf springs, which have actuation tabs pointing in the direction of the conductor insertion, as well as an insulating material housing with an actuation slide that can be slid into an opening in the top and rear.

Ausgehend hiervon ist es Aufgabe der vorliegenden Erfindung, eine verbesserte Leiteranschlussklemme zu schaffen, bei der die Handhabung mit Montageautomaten verbessert und die Wahrnehmbarkeit der Leiteranschlussklemme bei einer Verwendung in einer Leuchte verringert wird.Proceeding from this, it is an object of the present invention to provide an improved conductor terminal, in which handling with automatic assembly machines is improved and the perceptibility of the conductor terminal is reduced when used in a luminaire.

Die Aufgabe wird mit der Leiteranschlussklemme mit den Merkmalen des Anspruchs 1 sowie mit dem Set aus einer solchen Leiteranschlussklemme und Betätigungswerkzeug mit den Merkmalen des Anspruchs 17 gelöst. Vorteilhafte Ausführungsformen sind in den Unteransprüchen beschrieben. Für eine gattungsgemäße Leiteranschlussklemme wird vorgeschlagen, dass ein Verschlussdeckel zum Einrasten in den eingebuchteten Bereich vorgesehen ist, wobei die Tiefe des eingebuchteten Bereichs mindestens der Dicke einer üblichen Leiterplatte entspricht und wobei die Leiteranschlussklemme in eine Öffnung in der Leiterplatte derart einsetzbar ist, dass die Lötanschlussebene auf der Unterseite der Leiterplatte und die Leitereinsteckebene oberhalb der Oberseite der Leiterplatte liegt.The object is achieved with the conductor terminal with the features of claim 1 and with the set of such a conductor terminal and actuating tool with the features of claim 17. Advantageous embodiments are described in the subclaims. For a generic conductor connection terminal, it is proposed that a closure cover is provided for snapping into the indented area, the depth of the indented area corresponding at least to the thickness of a conventional printed circuit board and the conductor connection terminal being insertable into an opening in the circuit board in such a way that the solder connection level is on the underside of the circuit board and the plug-in level is above the top of the circuit board.

Zunächst einmal wird durch das Herausbiegen der Lötanschluss-Kontaktzungen aus der Ebene des Bodenabschnitts so, dass diese eine zur Ebene des Bodenabschnitts versetzt angeordnete Lötanschlussebene aufspannen, eine Reduzierung der Bauhöhe einer mit der Leiteranschlussklemme versehenen elektrischen Leiterplatte erreicht. Die Leiteranschlussklemmen können nämlich auf diese Weise in eine Öffnung der Leiterplatte eingehängt und an der Rückseite der Leiterplatte verlötet werden. Die Leiteranschlussklemme wird somit nicht einfach auf eine Leiterplatte aufgesetzt und an der Oberseite mit Lötanschlusskontakten verlötet. Durch diesen Ebenenversatz wird zudem ein eingebuchteter Bereich des Kontaktkörpers gebildet, in den ein Verschlussdeckel eingerastet werden kann. Mit diesem Verschlussdeckel wird eine Ansaugfläche für einen Montageautomaten zur Handhabung der Leiteranschlussklemme bereitgestellt. Zudem wird vermieden, dass sich eine Lichtfalle bzw. dunkle Flecken bilden, wenn sich auf der Seite der Lötanschlusskontakte auf der Leiterplatte aufgebrachte Leuchtelemente (z.B. Leuchtdioden LEDs) befinden. Je nach Anordnung solcher Leuchtelemente sowie der Ausbildung einer Streuscherbe können die Vertiefungen innerhalb der Leiteranschlussklemme durch eine Streuscherbe als "dunkle Flecken" wahrgenommen werden. Mit einem Verschlussdeckel wird die Wahrnehmbarkeit der benachbart zu Leuchtelementen angeordneten Leiteranschlussklemme reduziert.First of all, by bending the solder connection contact tongues out of the plane of the base section in such a way that they become one Clamp the level of the bottom section of the staggered solder connection level, reducing the height of an electrical circuit board provided with the conductor connection terminal. In this way, the conductor connection terminals can be hooked into an opening in the circuit board and soldered to the back of the circuit board. The conductor terminal is therefore not simply placed on a circuit board and soldered to the top with solder connection contacts. This offset of planes also forms an indented area of the contact body, into which a closure cover can be snapped. This cover provides a suction surface for an automatic assembly machine for handling the conductor connection terminal. In addition, it is avoided that a light trap or dark spots form if there are light elements (for example light-emitting diodes LEDs) on the circuit board on the side of the solder connection contacts. Depending on the arrangement of such lighting elements and the formation of a scattering shard, the depressions within the conductor connection terminal can be perceived as "dark spots" by a scattering shard. The perceptibility of the conductor connecting terminal arranged adjacent to lighting elements is reduced with a sealing cover.

Der Verschlussdeckel bildet dabei ein separates Teil zum Isolierstoffgehäuse, das mit dem Kontaktkörper verbunden wird und auch ohne das Isolierstoffgehäuse seine Funktion entfaltet.The sealing cover forms a separate part from the insulating material housing, which is connected to the contact body and also functions without the insulating material housing.

Der Verschlussdeckel kann Rastnasen haben, die zum Einrasten in Rastöffnungen im Kontaktkörper angepasst sind. Denkbar ist aber auch, dass der Verschlussdeckel Rastöffnungen oder Rastkanten hat, die zum Verrasten mit Rastnasen des Kontaktkörpers angepasst sind.The sealing cover can have latching lugs which are adapted for latching into latching openings in the contact body. However, it is also conceivable that the closure cover has latching openings or latching edges which are adapted for latching with latching lugs of the contact body.

Durch diese Verrastung des Verschlussdeckels mit dem Kontaktkörper werden Rastöffnungen an dem Isolierstoffgehäuse vermieden, welche die Luft- und Kriechstrecken verringern könnten.This latching of the closure cover with the contact body avoids latching openings on the insulating housing, which could reduce the air and creepage distances.

Der Verschlussdeckel kann von einer Deckelplatte des Verschlussdeckels lotrecht abragende Finger haben. Jeweils ein Paar solcher Finger ist dann einander gegenüberliegend im Abstand voneinander angeordnet und zum Eintauchen in den eingebuchteten Bereich zur Anlage jeweils angrenzend an einen vom Bodenabschnitt zu einer Lötanschluss-Kontaktzunge führenden Verbindungssteg des Kontaktkörpers angepasst. Auf diese Weise wird der Verschlussdeckel mit jeweils einem Paar solcher einander gegenüberliegenden Finger an einander gegenüberliegenden Verbindungsstegen mit voneinander weg weisenden Rastelementen eines Paares solcher Finger eingerastet. Während die Deckelplatte oberhalb der von den Lötanschluss-Kontaktzungen aufgespannten Ebene bleibt, tauchen die Finger in den eingebuchteten Bereich des Kontaktkörpers ein.The closure cover can have fingers protruding perpendicularly from a cover plate of the closure cover. A pair of such fingers is then arranged opposite one another at a distance from one another and is adapted for immersion in the indented area for abutment, in each case adjacent to a connecting web of the contact body that leads from the bottom section to a soldering contact tongue. In this way, the closure cover is snapped into place with a pair of such opposing fingers on mutually opposite connecting webs with locking elements of a pair of such fingers pointing away from one another. While the cover plate remains above the level spanned by the solder connection contact tongues, the fingers dip into the indented area of the contact body.

Die Finger können jeweils eine Mulde mit einer Rastkante haben. Die Mulden sind dann jeweils zur Aufnahme einer Rastnase des Kontaktkörpers ausgebildet. Eine solche Rastnase kann bspw. von einem Verbindungssteg abragen. Die Rastkante wird durch eine Begrenzungswand der Mulde gebildet.The fingers can each have a recess with a locking edge. The troughs are then each designed to receive a latching lug of the contact body. Such a catch can protrude from a connecting web, for example. The locking edge is formed by a boundary wall of the trough.

Mit einer solchen Mulde in einem Finger kann die Stabilität und Steifigkeit des Fingers verbessert werden. Die Seitenwände, welche die Mulde begrenzen, vergrößern den Widerstand des Fingers gegen elastische Verformung bei Kraftbeaufschlagung und Biegebeanspruchung.With such a depression in a finger, the stability and rigidity of the finger can be improved. The side walls that delimit the trough increase the resistance of the finger to elastic deformation when subjected to force and bending stress.

Die Finger können aber auch jeweils eine Rastnase haben, die zum Einrasten in eine Rastöffnung eines jeweils angrenzenden Verbindungsstegs des Kontaktkörpers ausgebildet ist.However, the fingers can also each have a locking lug, which is designed to snap into a locking opening of an adjacent connecting web of the contact body.

Zwischen zwei nebeneinander angeordneten Fingern des Verschlussdeckels können Abdeckzungen der Deckelplatte auf der Ebene der Deckelplatte abragen. Die Abdeckzungen können durch Schlitze von den in die Finger übergehenden Abschnitte der Deckelplatte freigestellt sein. Durch die Schlitze werden die Luft- und Kriechstrecken verbessert, insbesondere wenn das Isolierstoffgehäuse in diese Schlitze eintaucht.Cover tongues of the cover plate can protrude on the level of the cover plate between two fingers of the closure cover arranged next to one another. The cover tabs can be slotted through by the fingers Sections of the cover plate are free. The slots improve the air and creepage distances, especially when the insulating housing is immersed in these slots.

Der dem Bodenabschnitt gegenüberliegende Deckelabschnitt des Isolierstoffgehäuses kann auf der vom Bodenabschnitt abgewandten Seite des Federkraftklemmanschlusses nach oben hin in dem an die Seitenwandabschnitte und die mindestens eine Blattfederzunge des Kontaktkörpers angrenzenden Bereich vollständig geschlossen sein. Dabei kann das Isolierstoffgehäuse an der Rückseite, die der Leitereinführungsöffnung gegenüberliegt, eine Betätigungsöffnung haben, die zu Betätigungslaschen der mindestens einen Blattfederzunge hin führt. Die Betätigungsöffnung ist dabei unter Bildung eines Führungskanals durch den Deckelabschnitt des Isolierstoffgehäuses begrenzt.The cover section of the insulating material housing opposite the bottom section can be completely closed on the side of the spring-loaded terminal connection facing away from the bottom section in the area adjacent to the side wall sections and the at least one leaf spring tongue of the contact body. The insulating material housing on the rear side, which lies opposite the conductor insertion opening, can have an actuation opening that leads to actuation tabs of the at least one leaf spring tongue. The actuation opening is bounded by the cover section of the insulating material housing, forming a guide channel.

Damit stellt der Deckelabschnitt, der oberhalb der Feder des Federkraftklemmanschlusses an die mindestens eine Betätigungslasche angrenzt, eine Führungswand eines Führungskanals dar, an dem ein Betätigungswerkzeug oder ein in die Betätigungsöffnung hineingestecktes Betätigungswerkzeug oder ein verschiebbar in der Betätigungsöffnung eingebautes Betätigungselement geführt wird. Die Betätigung erfolgt dann ausschließlich über die von der Rückseite zugängliche Betätigungsöffnung, so dass die Betätigungskräfte nur als Scherkräfte auf Lötkontakte der Leiteranschlussklemme wirken.The cover section, which adjoins the at least one actuating tab above the spring of the spring-loaded terminal connection, thus represents a guide wall of a guide channel, on which an actuating tool or an actuating tool inserted into the actuating opening or an actuating element which is displaceably installed in the actuating opening is guided. The actuation then takes place exclusively via the actuation opening accessible from the rear, so that the actuation forces only act as shear forces on solder contacts of the conductor connection terminal.

Dadurch, dass der Deckelabschnitt angrenzend an den Federkraftklemmanschluss auf der dem Bodenabschnitt abgewandten Seite des Federkraftklemmanschlusses geschlossen ist, lässt sich die mindestens eine Blattfederzunge nur durch eine entgegengesetzt zur Leitereinsteckrichtung von der rückseitigen Betätigungsöffnung in Richtung zur fronseitigen Leitereinführungsöffnung gerichtete Betätigungskraft öffnen. Eine Kraftkomponente, die vom Deckelabschnitt zum Bodenabschnitt hin wirkt, wird vermieden, so dass die auf Lötstellen der Leiteranschlussklemme wirkenden Kräfte diese Lötstellen nicht beeinträchtigen.Because the cover section adjacent to the spring-loaded terminal connection on the side of the spring-loaded terminal connection facing away from the base section is closed, the at least one leaf spring tongue can only be opened by an operating force directed in the opposite direction to the conductor insertion direction from the rear actuation opening in the direction of the front conductor insertion opening. A force component that acts from the cover section to the bottom section is avoided, so that the forces acting on soldered joints of the conductor connection terminal do not impair these soldered joints.

Der Führungskanal der Betätigungsöffnung kann nicht nur durch den Deckelabschnitt, sondern auch durch voneinander beabstandete seitliche Innenwandabschnitte des Isolierstoffgehäuses und einen dem Deckelabschnitt gegenüberliegenden Sockelabschnitt gebildet werden. Damit ist der Führungskanal einseitig, beidseitig oder ggf. allseitig oder umlaufend durch Wandabschnitte begrenzt. Ein separates Betätigungswerkzeug wird damit optimal zu der mindestens einen Betätigungslasche geführt. Optional kann aber auch ein Betätigungselement in einem solchen Führungskanal eingebaut werden, der dann in der Betätigungsrichtung von der Frontseite zu der Rückseite hin verschiebbar gelagert wird.The guide channel of the actuation opening can be formed not only by the cover section, but also by spaced-apart lateral inner wall sections of the insulating material housing and a base section opposite the cover section. The guide channel is thus delimited on one side, on both sides or possibly on all sides or all around by wall sections. A separate actuating tool is thus optimally guided to the at least one actuating tab. Optionally, however, an actuating element can also be installed in such a guide channel, which is then slidably mounted in the actuating direction from the front to the rear.

Der Sockelabschnitt, der den Führungskanal in Richtung des Bodenabschnitts hin begrenzt, kann unter Bildung einer Leiteraufnahmetasche von dem Bodenabschnitt des Federkraftklemmanschlusses beabstandet sein. Damit wird einerseits eine Leiterauffangtasche zwischen dem Bodenabschnitt und dem Sockelabschnitt in Leitereinsteckrichtung hinter der durch die Klemmkante der mindestens einen Blattfederzunge gebildeten Klemmstelle zum Anklemmen eines elektrischen Leiters bereitgestellt. Zudem wird der Leitereinführungsbereich bzw. Leiteraufnahmebereich durch den Sockelabschnitt durch die darüber liegende Betätigungsebene abgegrenzt, in welche die jeweilige Betätigungslasche der mindestens einen Blattfeder hineinragen. Damit wird verhindert, dass die Betätigungsöffnung durch Litzen eines elektrischen Leiters versperrt werden.The base portion, which delimits the guide channel in the direction of the base portion, can be spaced from the base portion of the spring-loaded terminal connection to form a conductor receiving pocket. On the one hand, a conductor collection pocket is thus provided between the base section and the base section in the conductor insertion direction behind the clamping point formed by the clamping edge of the at least one leaf spring tongue for clamping an electrical conductor. In addition, the conductor insertion area or conductor receiving area is delimited by the base section through the actuation plane lying above, into which the respective actuation tab of the at least one leaf spring protrude. This prevents the actuation opening from being blocked by strands of an electrical conductor.

Der Führungskanal kann unmittelbar vor der mindestens einen Betätigungslasche enden, so dass der Führungskanal durch die Betätigungsöffnung gebildet ist und dann in die Betätigungslasche der Blattfeder und den darüber liegenden Deckelabschnitt übergeht. Für den Fall von zwei aufeinander zuweisend ausgerichteten Blattfedern wird die Betätigungsöffnung somit durch den Deckelabschnitt und die beiden voneinander beabstandeten Betätigungslaschen fortgesetzt. Im Deckelabschnitt des Isolierstoffgehäuses kann im rückseitigen Bereich, der der Leitereinführungsöffnung gegenüberliegt, eine Einbuchtung vorgesehen sein. Diese Einbuchtung geht dann in die zu den Betätigungslaschen führende Betätigungsöffnung über. Diese Einbuchtung hat den Vorteil, dass damit ein Positionierbereich bereitgestellt wird, in den ein Betätigungswerkzeug von oben, schräg von der Rückseite oder direkt von der Rückseite eingeführt wird. Durch die seitlichen Begrenzungswände der Einbuchtung und den Boden der Einbuchtung wird das Betätigungswerkzeug dann so positioniert, dass es an die an der Einbuchtung angrenzende Betätigungsöffnung eingeführt werden kann.The guide channel can end immediately in front of the at least one actuation tab, so that the guide channel is formed by the actuation opening and then merges into the actuation tab of the leaf spring and the cover section lying above it. In the case of two leaf springs facing one another, the actuating opening is thus through the cover section and the two spaced apart actuation tabs continued. An indentation can be provided in the cover section of the insulating material housing in the rear area, which is opposite the conductor insertion opening. This indentation then merges into the actuation opening leading to the actuation tabs. This indentation has the advantage that it provides a positioning area into which an actuating tool is inserted from above, obliquely from the rear or directly from the rear. The actuating tool is then positioned through the lateral boundary walls of the indentation and the bottom of the indentation such that it can be inserted into the actuating opening adjacent to the indentation.

Der Bodenabschnitt kann von der Kontur des Isolierstoffgehäuses heraus ragende Lötanschlusskontakte haben. Diese sind dann zum Auflöten auf eine Leiterplatte vorgesehen und können SMD-Kontakte zur OberflächenLötmontage oder Stiftkontakte zur Durchsteck-Lötmontage sein.The bottom section can have solder connection contacts protruding from the contour of the insulating material housing. These are then intended for soldering onto a printed circuit board and can be SMD contacts for surface solder mounting or pin contacts for push-through solder mounting.

Die Betätigungsöffnung kann zur Aufnahme eines separaten Betätigungswerkzeuges vorgesehen sein. Denkbar ist aber auch, dass sich die Betätigungsöffnung von der Rückseite bis zur Frontseite durch das Isolierstoffgehäuse hindurch erstreckt und an der Frontseite benachbart zu der Leitereinführungsöffnung ausmündet. Damit kann auch eine Betätigung von der Frontseite und/oder ein Prüfen des Spannungspotentials am Federkraftklemmanschluss an der Frontseite erfolgen. Bei dieser Ausführungsform ist es besonders vorteilhaft, wenn ein Betätigungselement verschiebbar in der Betätigungsöffnung aufgenommen ist. Das Betätigungselement kann dabei einen vorstehenden Betätigungsabschnitt haben, der zur Kraftbeaufschlagung der mindestens einen Betätigungslasche zum Öffnen der durch die Klemmkanten gebildeten Klemmstelle ausgebildet ist. Dieser vorstehende Betätigungsabschnitt befindet sich dann im Innenraum des Isolierstoffgehäuses im Bereich der Betätigungslasche der Blattfederzunge.The actuation opening can be provided for receiving a separate actuation tool. However, it is also conceivable that the actuation opening extends from the back to the front through the insulating material housing and opens out on the front side adjacent to the conductor insertion opening. This can also be used to actuate from the front and / or to check the voltage potential at the spring-loaded terminal connection on the front. In this embodiment, it is particularly advantageous if an actuating element is slidably received in the actuating opening. The actuating element can have a protruding actuating section which is designed to apply force to the at least one actuating lug to open the clamping point formed by the clamping edges. This protruding actuating section is then located in the interior of the insulating material housing in the area of the actuating tab of the leaf spring tongue.

Das Betätigungselement kann einen von der Rückseite des Isolierstoffgehäuses zur Kraftbeaufschlagung zugänglichen Kopfabschnitt und einen im geöffneten Zustand des Federkraftklemmanschlusses aus der Frontseite des Isolierstoffgehäuses herausragenden Signalabschnitt haben. Mit Hilfe dieses Signalabschnitts wird sichtbar, ob die an der Klemmkante der Blattfederzunge gebildete Klemmstelle geöffnet ist oder nicht. Zudem kann das Betätigungselement durch Kraftbeaufschlagung des Signalabschnitts in Richtung Rückseite wieder in die Ruhestellung zurückgeschoben werden, bei der die Blattfederzunge nicht durch das Betätigungselement beeinträchtigt wird und eine federelastische Klemmkraft auf einen eingesteckten und anzuklemmenden elektrischen Leiter ausübt.The actuating element can have a head section which is accessible from the rear of the insulating material housing for the application of force and a signal section which projects out of the front side of the insulating material housing when the spring-loaded terminal connection is open. With the help of this signal section it becomes visible whether the clamping point formed on the clamping edge of the leaf spring tongue is open or not. In addition, the actuating element can be pushed back into the rest position by applying force to the signal section in the direction of the rear, in which the leaf spring tongue is not impaired by the actuating element and exerts a resilient clamping force on an inserted and to be clamped electrical conductor.

Im Sinne der vorliegenden Erfindung ist unter dem unbestimmten Begriff "eine" kein Zahlwort zu verstehen. Wenn also z.B. von einem Federkraftklemmanschluss, einer Blattfeder oder einer Leitereinführungsöffnung bzw. Betätigungsöffnung die Rede ist, so ist dies im Sinne von "mindestens ein" zu interpretieren.For the purposes of the present invention, the indefinite term “a” is not to be understood as a numerical word. So if e.g. from a spring-cage connection, a leaf spring or a conductor insertion opening or actuation opening, this is to be interpreted in the sense of "at least one".

Das Isolierstoffgehäuse kann somit auch mehrere nebeneinander angeordnete Leitereinführungsöffnungen haben. Die Leiteranschlussklemme kann mehrere in dem Isolierstoffgehäuse nebeneinander aufgenommene und einer jeweiligen Leitereinführungsöffnung und einer Betätigungsöffnung zugeordnete Federkraftklemmanschlüsse haben.The insulating material housing can thus also have a plurality of conductor insertion openings arranged next to one another. The conductor connection terminal can have a plurality of spring-cage terminal connections which are accommodated next to one another in the insulating material housing and are assigned to a respective conductor insertion opening and an actuation opening.

Die Erfindung wird weiterhin durch das Set aus Leiteranschlussklemme und Betätigungswerkzeug gelöst, wobei das Betätigungswerkzeug einen Halteabschnitt und einen zum Einführen in die Betätigungsöffnung und zum Auseinanderdrücken der Betätigungslaschen der Klemmstelle ausgebildeten Betätigungsfinger hat. Bei dieser Ausführungsform ist ein separates Betätigungswerkzeug vorgesehen, das mit seinem mindestens einem Betätigungsfinger in eine zugeordnete Betätigungsöffnung des Isolierstoffgehäuses von der Rückseite einführbar ist, um dann durch Bewegung des Betätigungsfingers in Richtung Frontseite des Isolierstoffgehäuses zwischen die Betätigungslaschen geführt zu werden, um diese auseinander zu drängen.The invention is further achieved by the set consisting of a conductor connecting terminal and an actuating tool, the actuating tool having a holding section and an actuating finger designed for insertion into the actuating opening and for pushing apart the actuating tabs of the clamping point. In this embodiment, a separate actuating tool is provided, which with its at least one actuating finger an associated actuating opening of the insulating material housing can be inserted from the rear, in order then to be guided between the actuating tabs by moving the actuating finger in the direction of the front side of the insulating material housing in order to urge them apart.

Der Halteabschnitt und der Betätigungsfinger stehen dabei vorzugsweise im Winkel zueinander. Dieser Winkel kann bevorzugt im Bereich von etwa 90 Grad +/- 20 Grad liegen. Der Halteabschnitt und der mindestens eine Betätigungswinkel sind besonders vorzugsweise im rechten Winkel zueinander angeordnet.The holding section and the actuating finger are preferably at an angle to one another. This angle can preferably be in the range of approximately 90 degrees +/- 20 degrees. The holding section and the at least one actuation angle are particularly preferably arranged at right angles to one another.

An dem Halteabschnitt können eine Mehrzahl nebeneinander angeordnete und voneinander beabstandeter Betätigungsfinger zum Einführen in jeweils eine zugeordnete Betätigungsöffnung einer Mehrzahl von Betätigungsöffnungen des Isolierstoffgehäuses der Leiteranschlussklemme vorgesehen sein. Damit gelingt das Öffnen mehrerer Klemmstellen einer mehrpoligen Leiteranschlussklemme gleichzeitig, wodurch die Handhabung vereinfacht wird.A plurality of actuating fingers arranged next to one another and spaced apart from one another can be provided on the holding section for insertion into an associated actuating opening of a plurality of actuating openings of the insulating material housing of the conductor connection terminal. This makes it possible to open several terminal points of a multi-pole conductor terminal at the same time, which simplifies handling.

Figur 1 lässt eine perspektivische Ansicht einer ersten Ausführungsform einer Leiteranschlussklemme 1 erkennen, die ein Isolierstoffgehäuse 2 sowie eine Anzahl von in das Isolierstoffgehäuse 2 eingebauten Federkraftklemmanschlüssen 3 hat. Von den Federkraftklemmanschlüssen 3 sind aus dem Isolierstoffgehäuse 2 an der Front- und Rückseite jeweils herausragende Lötanschlusskontakte 4 sichtbar. Figure 1 shows a perspective view of a first embodiment of a conductor terminal 1, which has an insulating housing 2 and a number of spring-loaded terminal connections 3 installed in the insulating housing 2. Of the spring-cage terminal connections 3, outstanding solder connection contacts 4 are visible from the insulating housing 2 on the front and rear.

Deutlich wird, dass das Isolierstoffgehäuse 2 an der Frontseite Leitereinführungsöffnungen 5 zum Einführen jeweils eines elektrischen Leiters zu einer Klemmstelle hat, die an dem jeweiligen Federkraftklemmanschluss im Raum des Isolierstoffgehäuses 2 gebildet ist.It is clear that the insulating material housing 2 on the front side conductor insertion openings 5 for inserting an electrical conductor into each Has clamping point, which is formed on the respective spring clamp connection in the space of the insulating housing 2.

Im Bereich der Rückseite des Isolierstoffgehäuses 2, die der Frontseite mit der Leitereinführungsöffnung 5 gegenüberliegt, sind Einbuchtungen 6 in dem Isolierstoffgehäuse 2 vorhanden. Diese Einbuchtungen 6 gehen in Betätigungsöffnungen an der Rückseite über, welche in den Innenraum des Isolierstoffgehäuses 2 hineinführen.In the area of the rear side of the insulating material housing 2, which lies opposite the front side with the conductor insertion opening 5, indentations 6 are present in the insulating material housing 2. These indentations 6 merge into actuation openings on the rear, which lead into the interior of the insulating material housing 2.

Deutlich ist weiterhin, dass an der Frontseite den Leitereinführungsöffnungen 5 vorgelagert jeweils ein als Teil des Isolierstoffgehäuses 2 ausgebildeter Bodensockel 7a und an der Rückseite den Einbuchtungen 6 vorgelagert ebenfalls ein als Teil des Isolierstoffgehäuses 2 ausgebildeter Bodensockel 7b ist. Dieser dient zur Auflagerung auf eine Leiterplatte, wenn die Leiteranschlussklemme 1 in eine Öffnung einer Leiterplatte eingesetzt und auf der Rückseite der Leiterplatte mit den Lötanschlusskontakten 4 verlötet wird.It is also clear that on the front side of the conductor insertion openings 5 there is in each case a base base 7a formed as part of the insulating material housing 2 and on the rear side of the indentations 6 there is also a base base 7b formed as part of the insulating material housing 2. This is used for support on a circuit board if the conductor connection terminal 1 is inserted into an opening in a circuit board and is soldered to the solder connection contacts 4 on the back of the circuit board.

Figur 2 lässt eine perspektivische Ansicht des prinzipiellen Aufbaus eines Federkraftklemmanschlusses 3 für die Leiterplatte erkennen. Deutlich wird, dass der Federkraftklemmanschluss 3 aus einem Blechelement als Stanz- und Biegeteil einstückig ausgeformt ist. Dabei ist ein Bodenabschnitt 8 vorgesehen, von denen zwei voneinander beabstandete Seitenwandabschnitte 9 abragen. Durch die Seitenwandabschnitte 9 und den Bodenabschnitt 8 wird ein Leiteraufnahmekanal zur Aufnahme eines elektrischen Leiters gebildet. Der Leiteraufnahmekanal kann mindestens teilweise durch Begrenzungslaschen 10 auf der dem Bodenabschnitt 8 gegenüberliegenden Seite zumindest teilweise geschlossen sein, die aufeinander zuweisend von den Seitenwandabschnitten umgebogen sind. Die Oberseite des Leiteraufnahmekanals kann aber auch durch Abschnitte des Isolierstoffgehäuses 2 geschlossen werden. Figure 2 shows a perspective view of the basic structure of a spring-loaded terminal connection 3 for the circuit board. It becomes clear that the spring-loaded terminal connection 3 is formed in one piece from a sheet metal element as a stamped and bent part. A base section 8 is provided, from which two side wall sections 9, which are spaced apart, protrude. A conductor receiving channel for receiving an electrical conductor is formed by the side wall sections 9 and the bottom section 8. The conductor receiving channel can be at least partially closed at least partially by limiting tabs 10 on the side opposite the base section 8, which are bent toward one another and are bent over by the side wall sections. The top of the conductor receiving channel can also be closed by sections of the insulating housing 2.

Erkennbar ist, dass in dem dargestellten Ausführungsbeispiel zwei Blattfederzungen 11 von den Seitenwandabschnitten 9 in Leitereinsteckrichtung L abragen. Die Blattfederzungen 11 erstrecken sich annährend parallel zum Bodenabschnitt 8 und verlaufen aufeinander zuweisend. An den Enden der Blattfederzungen 11 sind jeweils Klemmkanten 12 zum Anklemmen eines elektrischen Leiters bzw. dessen abisolierten Endes gebildet. Alternativ ist auch eine Ausführungsform mit nur einer Blattfederzunge 11 denkbar, die z.B. mit einem Seitenwandabschnitt 9 oder einer davon abragenden Lasche eine Klemmstelle bildet.It can be seen that in the illustrated embodiment, two leaf spring tongues 11 protrude from the side wall sections 9 in the conductor insertion direction L. The leaf spring tongues 11 extend approximately parallel to the base section 8 and extend towards one another. At the ends of the leaf spring tongues 11 each clamping edges 12 for connecting an electrical conductor or its stripped end are formed. Alternatively, an embodiment with only one leaf spring tongue 11 is also conceivable, which, for example, forms a clamping point with a side wall section 9 or a tab protruding therefrom.

Deutlich wird auch, dass an den Blattfederzungen 11 an den Oberkanten, die den Bodenabschnitt 8 gegenüberliegen, Betätigungslaschen 13 abragen. Diese Betätigungslaschen 13 sind schräg voneinander weg weisend herausgestellt und zur Aufnahme eines Betätigungswerkzeuges oder Betätigungselementes vorgesehen. Sie erstrecken sich mit ihrem freien Ende in Leitereinsteckrichtung L bzw. in Erstreckungsrichtung der Blattfederzungen 11 und erweitern sich zu ihrem freien Ende hin trichterförmig. Mit Hilfe eines solchen zwischen die Betätigungslaschen 13 eingeführten Betätigungswerkzeuges oder Betätigungselementes werden die Blattfedern 11 voneinander weg bewegt, um die an den Klemmkanten 12 gebildete Klemmstelle zu öffnen und einen angeklemmten elektrischen Leiter entnehmen zu können.It is also clear that actuating tabs 13 protrude from the leaf spring tongues 11 at the upper edges, which lie opposite the bottom section 8. These actuation tabs 13 are pointed out at an angle away from one another and are provided for receiving an actuating tool or actuating element. They extend with their free end in the conductor insertion direction L or in the direction of extension of the leaf spring tongues 11 and expand in a funnel shape towards their free end. With the aid of such an actuating tool or actuating element inserted between the actuating tabs 13, the leaf springs 11 are moved away from one another in order to open the clamping point formed on the clamping edges 12 and to be able to remove a clamped-on electrical conductor.

Deutlich wird weiterhin, dass die Ebene des Bodenabschnitts 8 im Bereich der Seitenwandabschnitte 9 und der Blattfederzungen 11 relativ zur Ebene der Lötanschlusskontakte 4 angehoben bzw. versetzt ist, um auf diese Weise eine Einbuchtung bzw. einen Freiraum an der den Blattfederzungen 11 gegenüberliegenden Unterseite des Federkraftklemmanschlusses 3 zu bilden. Damit ist die durch den Leitereinführungskanal gebildete Leitereinsteckebene zum Einführen eines elektrischen Leiters von der durch die Lötanschlusskontakte 4 definierte Lötanschlussebene relativ weit versetzt angeordnet. Die Tiefe der Einbuchtung bzw. des Freiraums sollte mindestens der Dicke einer üblichen Leiterplatte entsprechen, so dass die Lötanschlussebene auf der Unterseite der Leiterplatte und die Leitereinsteckebene oberhalb der Oberseite der Leiterplatte liegt.It is also clear that the level of the base section 8 in the region of the side wall sections 9 and the leaf spring tongues 11 is raised or offset relative to the level of the solder connection contacts 4, in order in this way to provide an indentation or a free space on the underside of the spring-loaded terminal connection opposite the leaf spring tongues 11 3 form. The conductor insertion plane formed by the conductor insertion channel for inserting an electrical conductor is thus arranged at a relatively large offset from the solder connection plane defined by the solder connection contacts 4. The depth of the indentation or of the free space should at least correspond to the thickness of a conventional printed circuit board, so that the solder connection level on the underside of the PCB and the plug-in level is above the top of the circuit board.

Figur 3 lässt eine Seitenschnittansicht der Leiteranschlussklemme 1 aus Figur 1 erkennen. Deutlich wird, dass die Lötanschlusskontakte 4 auf der Rückseite einer Leiterplatte 14 mit dieser verlötet sind, wenn die Leiteranschlussklemme 1 in eine Öffnung 15 der Leiterplatte 14 eingesteckt ist. Die Bodensockel 7a, 7b des Isolierstoffgehäuses 2 sind auf der Unterseite der Leiterplatte 14 aufgelagert. Die Federkraftklemmanschlüsse 3 sind an dem Isolierstoffgehäuse 2 lagefixiert, indem Vorsprünge 16 des Isolierstoffgehäuses 2 durch zugeordnete Lagerungsöffnungen 17 des Bodenabschnitts 8 hineinragen. Figure 3 omits a sectional side view of conductor terminal 1 Figure 1 detect. It becomes clear that the solder connection contacts 4 on the back of a circuit board 14 are soldered to the latter when the conductor connection terminal 1 is inserted into an opening 15 in the circuit board 14. The base bases 7a, 7b of the insulating material housing 2 are supported on the underside of the printed circuit board 14. The spring-loaded terminal connections 3 are fixed in position on the insulating material housing 2, in that projections 16 of the insulating material housing 2 protrude through associated storage openings 17 of the base section 8.

Deutlich wird, dass die Ebene des Bodenabschnitts 8 im Innenraum des Isolierstoffgehäuses 2 im Vergleich zu der durch die Lötanschlusskontakte 4 gebildeten Ebene zum Deckelabschnitt 18 des Isolierstoffgehäuses 2 hin versetzt ist. Die Lötanschlusskontakte 4 sind somit weiter nach unten gezogen, um so eine Rückseitenmontage an der Leiterplatte 14 zu ermöglichen.It becomes clear that the level of the bottom section 8 in the interior of the insulating material housing 2 is offset in relation to the level formed by the solder connection contacts 4 to the cover section 18 of the insulating material housing 2. The solder connection contacts 4 are thus pulled further down, so as to enable rear mounting on the printed circuit board 14.

Deutlich wird, dass der Deckelabschnitt 18 oberhalb des Federkraftklemmanschlusses 3 im Bereich der Blattfedern 11 und insbesondere der Betätigungslaschen 13 vollständig geschlossen ist. Der Deckelabschnitt 18 setzt sich zur Rückseite des Isolierstoffgehäuses 2, die der Leitereinführungsöffnung 5 gegenüberliegt, weiter fort, um so eine Betätigungsöffnung 19 zum Einführen eines Betätigungswerkzeuges 20 zu begrenzen. Gegenüberliegend zum Deckelabschnitt 18 ist die Betätigungsöffnung 19 durch einen Sockelabschnitt 21 begrenzt. Dieser Sockelabschnitt 21 ist im Abstand zu dem Bodenabschnitt 8 des Federkraftklemmanschlusses 3 angeordnet, um eine Leiterauffangtasche 22 zu begrenzen. Ein von der Leitereinführungsöffnung 5 an den Blattfedern 11 vorbeigeführter elektrischer Leiter wird somit mit seinem abisolierten freien Ende durch den Bodenabschnitt 8 und den darüber liegenden Sockelabschnitt 21 in die Leiterauffangtasche 22 geführt. Der über dem Sockelabschnitt 21 liegende Freiraum der Betätigungsöffnung 19 wird somit von etwaigen Litzen eines eingesteckten und angeklemmten elektrischen Leiters freigehalten.It is clear that the cover section 18 above the spring-loaded terminal connection 3 in the area of the leaf springs 11 and in particular the actuating tabs 13 is completely closed. The cover section 18 continues to the rear of the insulating material housing 2, which lies opposite the conductor insertion opening 5, so as to limit an actuating opening 19 for inserting an actuating tool 20. Opposite the cover section 18, the actuation opening 19 is delimited by a base section 21. This base section 21 is arranged at a distance from the bottom section 8 of the spring-loaded terminal connection 3 in order to limit a conductor collecting pocket 22. An stripped free end of an electrical conductor guided past the leaf springs 11 from the conductor insertion opening 5 is thus guided through the base section 8 and the base section 21 lying above it into the conductor collection pocket 22. The one above the base section 21 Free space of the actuation opening 19 is thus kept free of any strands of an inserted and clamped electrical conductor.

Deutlich wird weiterhin, dass die Betätigungslaschen 13 in Leitereinsteckrichtung L von dem Klemmende 12 weiter in Richtung Sockelabschnitt 21 herausragen. Wenn nun ein von einem Halteabschnitt 23 des Betätigungswerkzeuges 20 abragender Betätigungsfinger 24 in die Betätigungsöffnung 19 eingeführt wird, so wirkt er auf die einander gegenüberliegenden Betätigungslaschen 13 und drückt diese auf einer Betätigungsebene auseinander. Diese Betätigungsebene liegt oberhalb der Leiteranklemmebene, die durch die Klemmkanten 12 und die sich daran anschließende Leiterauffangtasche gebildet ist und die durch den Sockelabschnitt 21 nach oben zur Betätigungsöffnung 19 hin begrenzt ist.It is also clear that the actuating tabs 13 protrude further from the terminal end 12 in the direction of the plug-in direction L in the direction of the base section 21. If an actuating finger 24 projecting from a holding section 23 of the actuating tool 20 is now inserted into the actuating opening 19, it acts on the actuating tabs 13 lying opposite one another and presses them apart on an actuating plane. This actuation plane lies above the conductor clamping plane, which is formed by the clamping edges 12 and the adjoining conductor catch pocket and which is delimited upwards by the base section 21 towards the actuation opening 19.

Das Öffnen der Klemmstelle des Federkraftklemmanschlusses 3 erfolgt somit durch eine Betätigungskraft, die in Pfeilrichtung B entgegengesetzt zur Leitereinsteckrichtung L wirkt. Die Betätigungskraft B übt dabei allenfalls eine Scherkraft auf die Lötanschlusskontakte 4 aus. Eine quer zur Fläche der Leiterplatte 14 wirkende Betätigungskraft wird vermieden, welche die Lötstellen an den Lotanschlusskontakten 4 beeinträchtigen könnte.The clamping point of the spring-loaded terminal connection 3 is thus opened by an actuating force which acts in the direction of arrow B opposite to the direction of insertion of the conductor L. The actuating force B exerts a shear force on the solder connection contacts 4 at best. An actuating force acting transversely to the surface of the printed circuit board 14 is avoided, which could impair the soldering points on the solder connection contacts 4.

Weiterhin ist erkennbar, dass von der Unterseite ein Gehäuseteil in Form eines Verschlussdeckels 40 in den eingebuchteten Bereich des Bodenabschnitts 8 eingerastet ist. Auch hier rasten Vorsprünge in Form von Rastnasen 56 in Rastöffnungen im Blechmaterial des Bodenabschnittes 8 ein. Mit diesem Verschlussdeckel 40 wird eine Ansaugfläche für einen Montageautomaten zur Handhabung der Leiteranschlussklemme 1 bereitgestellt. Zudem wird vermieden, dass sich eine Lichtfalle bzw. dunkle Flecken bilden, wenn sich auf der Seite der Lötanschlusskontakte 4 auf der Leiterplatte 14 aufgebrachte Leuchtelemente (z.B. Leuchtdioden LEDs) befinden. Je nach Anordnung solcher Leuchtelemente sowie der Ausbildung einer Streuscheibe können die Vertiefungen innerhalb der Leiteranschlussklemme 1 durch eine Streuscheibe als "dunkle Flecken" wahrgenommen werden.Furthermore, it can be seen that a housing part in the form of a closure cover 40 is snapped into the indented area of the base section 8 from the underside. Here too, projections in the form of locking lugs 56 snap into locking openings in the sheet material of the base section 8. With this cover 40, a suction surface for an automatic assembly machine for handling the conductor terminal 1 is provided. In addition, it is avoided that a light trap or dark spots form if there are light-emitting elements (for example light-emitting diodes LEDs) on the circuit board 14 on the side of the solder connection contacts 4. Depending on the arrangement of such lighting elements and the formation of a diffusing screen, the depressions can are perceived as "dark spots" within the conductor connection terminal 1 by a diffusing screen.

Der Verschlussdeckel 40 ist optional. Ohne einen solchen Verschlussdeckel 40 kann u.U. auch der Bodenabschnitt 8 selbst als Ansaugfläche für einen Montageautomaten genutzt werden.The closure cover 40 is optional. Without such a sealing cover 40, also the bottom section 8 itself can be used as a suction surface for an automatic assembly machine.

Figur 4 lässt eine perspektivische Rückseitenansicht der Leiteranschlussklemme 1 aus Figuren 1 und 3 erkennen. Es wird deutlich, dass die Einbuchtungen 6 jeweils durch den Sockelabschnitt 21 als Bodenfläche und einander gegenüberliegenden Innenwandflächen 25 des Isolierstoffgehäuses 2 begrenzt sind. Hit Hilfe dieser Einbuchtungen wird die Einführung des Betätigungswerkzeuges 21 in die Betätigungseinbuchtung 19 erleichtert, indem die Einbuchtung 6 einen trichterförmigen Einführungsbereich bereitstellt. Figure 4 omits a perspective rear view of the conductor terminal 1 Figures 1 and 3rd detect. It is clear that the indentations 6 are each delimited by the base section 21 as the bottom surface and opposite inner wall surfaces 25 of the insulating material housing 2. With the help of these indentations, the insertion of the actuating tool 21 into the actuating indentation 19 is facilitated in that the indentation 6 provides a funnel-shaped insertion area.

Figur 5 lässt eine perspektivische Ansicht der in eine Leiterplatte 14 eingesetzten Leiteranschlussklemme 1 erkennen. Deutlich wird, dass die Leiterplatte 14 eine rechteckförmige Öffnung hat, in die die Leiteranschlussklemme 1 von der Unterseite eingesteckt wird. Die Leitereinführungsöffnung 5 mündet dabei aber auf der Ebene der Oberseite der Leiterplatte 14 oder ggf. leicht darüber aus. Durch einen solchen Einbau kann die Bauhöhe eines elektrischen Gerätes im Vergleich zum einfachen Auflöten einer einfachen Leiteranschlussklemme 1 auf die Oberseite der Leiterplatte 14 reduziert werden. Figure 5 shows a perspective view of the conductor terminal 1 inserted into a circuit board 14. It is clear that the circuit board 14 has a rectangular opening into which the conductor terminal 1 is inserted from the underside. However, the conductor insertion opening 5 opens out at the level of the top of the circuit board 14 or possibly slightly above it. Such an installation allows the overall height of an electrical device to be reduced compared to the simple soldering of a simple conductor connection terminal 1 onto the upper side of the printed circuit board 14.

Figur 6 lässt eine perspektivische Ansicht der Leiteranschlussklemme 1 aus Figur 5 ohne Isolierstoffgehäuse 2 erkennen. Dabei ist die Lage der nebeneinander angeordneten mehreren Federkraftklemmanschlüssen 3 in der Aufnahmeöffnung 15 der Leiterplatte 14 sichtbar. Deutlich wird, dass von den Blattfedern 11 auf der Oberseite, die dem Bodenabschnitt 8 gegenüberliegt, jeweils Betätigungslaschen 13 abragen. Diese erstrecken sich von den Endbereichen der Blattfederzungen 11 mit den Klemmkanten 12 über die Klemmkanten 12 hinaus. Ein Paar von solchen Betätigungslaschen 13 eines Federkraftklemmanschlusses 3 ist mit ihren freien Enden voneinander wegweisend abgebogen, um einen Einführungstrichter für den Betätigungsfinger 24 eines Betätigungswerkzeuges 20 zu bilden. Figure 6 omits a perspective view of the conductor terminal 1 Figure 5 Detect without insulating housing 2. The position of the several spring-loaded terminal connections 3 arranged next to one another is visible in the receiving opening 15 of the printed circuit board 14. It is clear that actuating tabs 13 each protrude from the leaf springs 11 on the upper side, which is opposite the bottom section 8. These extend from the end regions of the leaf spring tongues 11 with the clamping edges 12 over the clamping edges 12 beyond. A pair of such actuation tabs 13 of a spring-loaded terminal connection 3 are bent with their free ends pointing away from one another in order to form an insertion funnel for the actuation finger 24 of an actuation tool 20.

In der dargestellten Ruheposition sind die Klemmkanten 12 der Blattfedern 11 eines Federkraftklemmanschlusses 3 durch die Federkraft der Blattfedern 11 aufeinander zu gerichtet. Die Klemmkanten 12 können dann ohne angeklemmten elektrischen Leiter aneinander anliegen. Wenn nun ein elektrischer Leiter an den Seitenwänden 9 und den Blattfedern 11 vorbei zu den Klemmkanten 12 geführt wird, dann wird dieser durch die Klemmkraft der Blattfedern an den Federkraftklemmanschluss 3 angeklemmt.In the rest position shown, the clamping edges 12 of the leaf springs 11 of a spring force clamping connection 3 are directed towards one another by the spring force of the leaf springs 11. The clamping edges 12 can then rest against one another without a clamped electrical conductor. If an electrical conductor is now guided past the side walls 9 and the leaf springs 11 to the clamping edges 12, then this is clamped to the spring-force clamping connection 3 by the clamping force of the leaf springs.

Figur 7 lässt die Anordnung auf Figur 6 mit Leiterplatte 14 und darin in eine Aufnahmeöffnung eingesetzten Federkraftklemmanschlüssen 3 erkennen. Nunmehr ist das Betätigungswerkzeug 20 in den vorderen, rechten Federkraftklemmanschluss so eingesteckt, dass der Betätigungsfinger 24 zwischen den Betätigungslaschen 13 platziert ist. Dadurch werden die beiden einander gegenüberliegenden Blattfedern 11 des Federkraftklemmanschlusses 3 voneinander weg bewegt, um so die an den einander gegenüberliegenden Klemmkanten 12 gebildete Klemmstelle zum Anklemmen eines elektrischen Leiters zu öffnen. Deutlich wird, dass der Betätigungsfinger 24 auf einer Ebene oberhalb der durch die Blattfedern 11 gebildeten Klemmebene zum Anklemmen eines elektrischen Leiters liegt. Deutlich wird weiterhin, dass der Betätigungsfinger 24 in eine Richtung bewegt wird, die im Wesentlichen der Erstreckungsrichtung der Blattfedern 11 entspricht und annährend parallel zur Oberfläche der Leiterplatte 14 liegt. Figure 7 leaves the arrangement open Figure 6 Detect with printed circuit board 14 and spring-loaded terminal connections 3 inserted therein into a receiving opening. The actuating tool 20 is now inserted into the front, right spring force terminal connection in such a way that the actuating finger 24 is placed between the actuating tabs 13. As a result, the two opposite leaf springs 11 of the spring-loaded terminal connection 3 are moved away from one another so as to open the clamping point formed on the mutually opposite clamping edges 12 for clamping an electrical conductor. It becomes clear that the actuating finger 24 lies on a level above the clamping level formed by the leaf springs 11 for connecting an electrical conductor. It also becomes clear that the actuating finger 24 is moved in a direction which essentially corresponds to the direction of extension of the leaf springs 11 and is approximately parallel to the surface of the printed circuit board 14.

Figur 8 lässt eine perspektivische Rückseitenansicht der Leiteranschlussklemme 1 erkennen. Hierbei wird nochmals deutlich, dass das Isolierstoffgehäuse 2 mit Vorsprüngen 16 in Lageröffnungen 17 des Bodenabschnitts 8 eines Federkraftklemmanschlusses 3 lagefixiert ist. Erkennbar ist auch, dass die Lötanschlusskontakte 4 auf die Auflageebene der Bodensockel 7a, 7b des Isolierstoffgehäuses 2 herumgebogen sind. Figure 8 shows a perspective rear view of the conductor terminal 1. It is again clear here that the insulating material housing 2 with projections 16 in bearing openings 17 of the base section 8 of a spring-loaded terminal connection 3 is fixed in position. It can also be seen that the solder connection contacts 4 are bent around on the support plane of the base bases 7a, 7b of the insulating material housing 2.

Figur 9 lässt eine Ansicht der Leiteranschlussklemme 1 aus Figur 8 im montierten Zustand erkennen, bei dem die Leiteranschlussklemme1 von der Rückseite in eine Aufnahmeöffnung 15 der Leiterplatte 14 eingesetzt ist. Deutlich wird, dass die Lötanschlusskontakte 4 nunmehr auf der Oberfläche der Rückseite der Leiterplatte 14 aufliegen, um dort mittels Oberflächenlötmontage mit der Leiterplatte 14 verlötet zu werden. Figure 9 omits a view of conductor connection terminal 1 Figure 8 recognize in the assembled state, in which the conductor terminal 1 is inserted from the rear into a receiving opening 15 of the circuit board 14. It becomes clear that the solder connection contacts 4 now rest on the surface of the back of the printed circuit board 14 in order to be soldered to the printed circuit board 14 there by means of surface solder mounting.

Dadurch, dass die Betätigungsöffnung die Betätigungskraft zwingend auf eine annährend parallel zur Oberfläche der Leiterplatte 14 wirkende Betätigungskraft reduziert, werden die Lötanschlusskontakte 4 bzw. die dortigen Lötverbindungen mit der Leiterplatte 14 nur auf Scherkräfte belastet.Because the actuating opening necessarily reduces the actuating force to an actuating force acting approximately parallel to the surface of the printed circuit board 14, the solder connection contacts 4 or the solder connections there with the printed circuit board 14 are only subjected to shear forces.

Auch hier ist der Verschlussdeckel 40 erkennbar, der die eingebuchteten Abschnitte des Bodenabschnittes 8 verschließt.The closure cover 40, which closes the indented portions of the base portion 8, can also be seen here.

Figur 10 zeigt eine Seiten-Schnittansicht durch eine zweite Ausführungsform einer Leiteranschlussklemme 1 in einem in eine Leiterplatte 14 eingesetzten Zustand. Der Federkraftklemmanschluss 3 der Leiteranschlussklemme 1 hat, wie im ersten Ausführungsbeispiel einen aus einem Blechelement geformten Kontaktkörper mit einem Bodenabschnitt 8, von dem Bodenabschnitt 8 abragenden, voneinander beabstandeten Seitenwandabschnitten 9 und Lötanschluss-Kontaktzungen 4. Die Lötanschluss-Kontaktzungen 4 sind aus der Ebene des Bodenabschnitts 8, an den sich die Blattfederzungen 11 anschließen, herausgebogen und spannen eine versetzt zur Ebene des Bodenabschnitts 8 angeordnete Lötanschlussebene auf. Deutlich wird, dass die Leiteranschlussklemme 1 wiederum in eine Öffnung der Leiterplatte 14 eingesetzt ist, sodass die Lötanschlussebene mit den Lötanschluss-Kontaktzungen 4 auf der Seite der Leiterplatte 14 ist, die der Leitereinführungsseite mit der Leitereinführungsöffnung 5 gegenüberliegt. Figure 10 shows a side sectional view through a second embodiment of a conductor terminal 1 in a state inserted into a circuit board 14. The spring-loaded terminal connection 3 of the conductor connection terminal 1 has, as in the first exemplary embodiment, a contact body formed from a sheet metal element and having a bottom section 8, side wall sections 9 projecting from the bottom section 8 and spaced apart from one another and solder connection contact tongues 4. The solder connection contact tongues 4 are from the plane of the bottom section 8, to which the leaf spring tongues 11 connect, are bent out and span a solder connection plane arranged offset to the level of the base section 8. It becomes clear that the conductor connection terminal 1 is in turn inserted into an opening in the printed circuit board 14, so that the solder connection level with the solder connection contact tongues 4 is the side of the circuit board 14 which is opposite to the conductor insertion side with the conductor insertion opening 5.

Durch diesen Ebenenversatz wird ein Freiraum zum Einrasten eines Verschlussdeckels 40 geschaffen.This level offset creates a free space for locking a closure cover 40.

Im Unterschied zur ersten Ausführungsform hat der Verschlussdeckel 40 von der Deckelplatte 41 des Verschlussdeckels lotrecht abragende Finger 42a, 42b. Ein solches Paar solcher einander im Abstand voneinander gegenüberliegend angeordneter Finger 42a, 42b. Diese Finger 42a, 42b sind so an den Federkraftklemmanschluss 3 angepasst, dass sie in den eingebuchteten Bereich des Federkraftklemmanschlusses 3 eintauchen und an den Verbindungsstegen 50 anliegen, welche den Bodenabschnitt 8 mit den Kontaktzungen 4 verbinden. Die Verbindungsstege 50 begrenzen den eingebuchteten Bereich und sind quer zur Ebene des Bodenabschnitts 8 und der von den Lötanschluss-Kontaktzungen 4 aufgespannten Ebene ausgerichtet.In contrast to the first embodiment, the closure cover 40 has fingers 42a, 42b projecting perpendicularly from the cover plate 41 of the closure cover. Such a pair of such fingers 42a, 42b arranged at a distance from one another. These fingers 42a, 42b are adapted to the spring-loaded terminal connection 3 in such a way that they plunge into the indented area of the spring-loaded terminal connection 3 and bear against the connecting webs 50, which connect the base section 8 to the contact tongues 4. The connecting webs 50 delimit the indented area and are aligned transversely to the plane of the base section 8 and the plane spanned by the solder connection contact tongues 4.

Erkennbar ist, dass an den Verbindungsstegen 50 Rastnasen 57 ausgebildet sind, welche zusammen mit einer Rastkontur des jeweils angrenzenden Fingers 42a, 42b einen Anschlag zur Verrastung des Verschlussdeckels 40 an dem Federkraftklemmanschluss 30 bilden. Die Rastnasen 57 sind in dem dargestellten Ausführungsbeispiel aus dem Blechmaterial des Federkraftklemmanschlusses 3 gebildet. Hierzu sind Materiallappen von dem Blechmaterial freigeschnitten und aus der Ebene der Verbindungsstege 50 schräg herausgestellt.It can be seen that latching lugs 57 are formed on the connecting webs 50, which, together with a latching contour of the respectively adjacent finger 42a, 42b, form a stop for latching the closure cover 40 on the spring-loaded terminal connection 30. The locking lugs 57 are formed in the illustrated embodiment from the sheet metal material of the spring-cage connection 3. For this purpose, material tabs are cut free from the sheet material and protruded obliquely from the plane of the connecting webs 50.

Dies ist aus Figur 11 deutlicher erkennbar. Figur 11 zeigt eine perspektivische Ansicht des prinzipiellen Aufbaus des Federkraftklemmanschlusses 3 von der Unterseite. Dabei kann im Wesentlichen auf die Beschreibung des Federkraftklemmanschlusses zu Figur 2 verwiesen werden. Zur Verrastung des Verschlussdeckels 40 sind bei diesem Ausführungsbeispiel jedoch keine Rastöffnungen, sondern Rastnasen 57 in Form von aus der Ebene der Verbindungsstege 50 schräg herausgestellter Materiallappen vorgesehen. Diese bilden einen Anschlag für die Rastkontur des Verschlussdeckels 40.This is over Figure 11 more clearly recognizable. Figure 11 shows a perspective view of the basic structure of the spring clamp connection 3 from the bottom. It can essentially refer to the description of the spring-cage connection Figure 2 to get expelled. In this exemplary embodiment, however, there are no latching openings for latching the closure cover 40, but locking lugs 57 in the form of material tabs protruding out of the plane of the connecting webs 50 are provided. These form a stop for the locking contour of the closure cover 40.

Figur 12 zeigt eine perspektivische Ansicht des Verschlussdeckels 40 des Federkraftklemmanschlusses 3 aus Figur 10. Deutlich wird, dass für jeden Federkraftklemmanschluss 3 jeweils ein Paar einander gegenüberliegender Finger 42a, 42b im Abstand voneinander angeordnet sind. Diese Finger 42a, 42b ragen quer von der Ebene der Deckelplatte 41 ab. Die Rastkontur der Finger 42a, 42b zur Verrastung mit den Rastnasen 57 ist in diesem Ausführungsbeispiel durch jeweils eine in einen Finger 42a, 42b eingebrachte Mulde 45 ausgeführt. Zur Verrastung mit einer vorstehenden Rastnase 57 des Federkraftklemmanschlusses 3 muss die Rastkontur jedenfalls eine mit der Rastnase 57 zusammenwirkende Anschlagfläche haben, die nicht notwendigerweise mit einer Mulde 45 ausgeführt sein muss. Figure 12 shows a perspective view of the closure cover 40 of the spring-loaded terminal connection 3 Figure 10 . It is clear that a pair of opposing fingers 42a, 42b are arranged at a distance from each other for each spring-loaded terminal connection 3. These fingers 42a, 42b project transversely from the plane of the cover plate 41. In this exemplary embodiment, the latching contour of the fingers 42a, 42b for latching with the latching lugs 57 is in each case implemented by a depression 45 which is introduced into a finger 42a, 42b. For latching with a protruding latching lug 57 of the spring-loaded terminal connection 3, the latching contour must in any case have a stop surface which interacts with the latching lug 57 and does not necessarily have to be designed with a trough 45.

Ferner ist erkennbar, dass jeweils zwischen zwei benachbarten Fingern 42a bzw. 42b Abdeckzungen 43 der Deckelplatte 41 vorhanden sind, die auf der Ebene der Deckelplatte 41 abragen und durch Schlitze 44 von den in die Finger 42a, 42b übergehenden Abschnitte der Deckelplatte 41 freigestellt sind. Diese Schlitze 44 dienen zur Aufnahme von Gehäusewandabschnitten des Isolierstoffgehäuses 2 und tragen zur Vergrößerung der Luft- und Kriechstrecken zwischen dem Federkraftklemmanschluss 3 und der Außenseite und damit zur verbesserten elektrischen Isolierung bei.It can also be seen that cover tongues 43 of the cover plate 41 are present between two adjacent fingers 42a and 42b, respectively, which protrude at the level of the cover plate 41 and are released by slots 44 from the sections of the cover plate 41 which merge into the fingers 42a, 42b. These slots 44 serve to receive housing wall sections of the insulating material housing 2 and contribute to increasing the air and creepage distances between the spring-loaded terminal connection 3 and the outside and thus to improving the electrical insulation.

Figur 13 zeigt eine perspektivische Ansicht auf die Unterseite des Isolierstoffgehäuses 2. Erkennbar ist, dass dieses Isolierstoffgehäuse 2 durch Zwischenwände 46 in Kammern aufgeteilt ist. Dabei sind durch eine Leerkammer voneinander beabstandete Aufnahmekammern zur Aufnahme jeweils eines Federkraftklemmanschlusses vorgesehen. Die stegartig verbleibenden Wandabschnitte 47 an der Oberkante der Zwischenwände 46 sind zum Eintauchen in jeweils einen zugeordneten Schlitz 44 des Verschlussdeckels 40 vorgesehen. Der Verschlussdeckel 40 taucht in den vertieften Bereich der Zwischenwände 46 ein, um bündig mit der Ebene der Unterseite des Isolierstoffgehäuses 2 abzuschließen. Figure 13 shows a perspective view of the underside of the insulating material housing 2. It can be seen that this insulating material housing 2 is divided into chambers by partition walls 46. In this case, receiving chambers spaced apart from one another by an empty chamber are provided for receiving a spring-loaded terminal connection in each case. The web-like remaining wall sections 47 on the upper edge of the intermediate walls 46 are for immersion in an associated slot 44 of the closure cover 40 is provided in each case. The closure cover 40 dips into the recessed area of the intermediate walls 46 in order to be flush with the plane of the underside of the insulating material housing 2.

Erkennbar ist weiterhin, dass die Aufnahmekammern für die Federkraftklemmanschlüsse 3 zur Frontseite und Rückseite hin Vertiefungen 48 haben, durch die die Lötanschlussflächen, d.h. die sich an die Verbindungsstege 50 anschließenden Abschnitte des Federkraftklemmanschlusses 3 eintauchen.It can also be seen that the receiving chambers for the spring-cage terminal connections 3 have depressions 48 towards the front and rear through which the soldering connection surfaces, i.e. the sections of the spring-loaded terminal connection 3 adjoining the connecting webs 50 are immersed.

In dem dargestellten Ausführungsbeispiel ragen beidseits der Vertiefungen 48 Arretiervorsprünge 49a ein. Diese können wie dargestellt teilkreisförmig sein. Andere Formen sind denkbar. Ein in eine Aufnahmekammer eingesetzter Federkraftklemmanschluss 3 wird mit diesem Arretiervorsprüngen 49a lagefixiert. Hierzu haben die Federkraftklemmanschlüsse 3 wie in Figur 11 dargestellt korrespondierende Arretiereinbuchtungen 49b, in die die Arretiervorsprünge 49a eintauchen.In the exemplary embodiment shown, locking projections 49a protrude on both sides of the depressions. As shown, these can be part-circular. Other shapes are possible. A spring-loaded terminal connection 3 inserted into a receiving chamber is fixed in position with this locking projections 49a. For this purpose, the spring clamp connections 3 as in Figure 11 shown corresponding locking indentations 49b, into which the locking projections 49a dip.

Figur 14 lässt eine perspektivische Ansicht der zweiten Ausführungsform der Leiteranschlussklemme 1 von der Unterseite erkennen. Das Isolierstoffgehäuse 2 ist mit Federkraftklemmanschlüssen 3 bestückt, deren Lötanschlussflächen aus dem Isolierstoffgehäuse 2 herausragen. Deutlich wird, dass der Verschlussdeckel 40 bündig in Vertiefungen des Isolierstoffgehäuses 2 eingesetzt ist, sodass die Finger 42a, 42b in den eingebuchteten Bereich der Federkraftklemmanschlüsse 3 hineinragen und dort mit den Federkraftklemmanschlüssen 3 verrasten. Figure 14 shows a perspective view of the second embodiment of the conductor terminal 1 from the bottom. The insulating material housing 2 is equipped with spring-cage terminal connections 3, the soldering connection surfaces of which protrude from the insulating material housing 2. It becomes clear that the closure cover 40 is inserted flush in recesses in the insulating material housing 2, so that the fingers 42a, 42b protrude into the indented area of the spring-loaded terminal connections 3 and latch there with the spring-loaded terminal connections 3.

Erkennbar ist auch, dass die Abdeckzungen 43 die Zwischenkammern die Abdeckung bei stegartigen Wandabschnitte 47 in die Schlitze 44 zwischen jeweils einer Abdeckzunge 43 und dem in einen Finger 42a, 42b übergehenden Abschnitte der Deckelplatte 41 hineinragen. Damit wird der Verschlussdeckel 40 lagefixiert und die Luft- und Kriechstrecken werden optimiert.It can also be seen that the cover tongues 43, the intermediate chambers, the cover, in the case of web-like wall sections 47, protrude into the slots 44 between a cover tongue 43 and the section of the cover plate 41 which merges into a finger 42a, 42b. With this, the sealing cover 40 fixed in position and the air and creepage distances are optimized.

Figur 15 zeigt eine perspektivische Ansicht der Leiteranschlussklemme 1 aus Figur 14 von der Oberseite mit Blick auf die Rückseite. An der Rückseite sind Betätigungsöffnungen 19 vorhanden, die zu den Betätigungslaschen 13 eines Federkraftklemmanschlusses 3 führen. Figure 15 shows a perspective view of the conductor terminal 1 from Figure 14 from the top facing the back. At the back there are actuation openings 19 which lead to the actuation tabs 13 of a spring-loaded terminal connection 3.

An der Oberseite des Isolierstoffgehäuses 2 sind optional Prüföffnungen 51 eingebracht. Es können Prüfstifte in die Prüföffnungen 51 eingeführt werden, um das an einem Federkraftklemmanschluss 3 befindliche elektrische Potential zu messen. Denkbar ist aber auch, dass die Prüföffnungen 51 als Betätigungsöffnungen genutzt werden.Test openings 51 are optionally made on the upper side of the insulating material housing 2. Test pins can be inserted into the test openings 51 in order to measure the electrical potential located at a spring-loaded terminal connection 3. However, it is also conceivable that the test openings 51 are used as actuation openings.

Weiterhin wird deutlich, dass das Isolierstoffgehäuse 2 insbesondere an der Frontseite und Rückseite einen Kragen 52 hat. Dieser Kragen 52 ist zur Auflage auf die Unterseite einer Leiterplatte vorgesehen, um die Leiteranschlussklemme 1 auf einer Leiterplatte aufzulegen und die auf die Lötverbindungen an den Lötanschlussflächen mit der Leiterplatte wirkenden Kräfte möglichst stark zu reduzieren.It is also clear that the insulating material housing 2 has a collar 52, in particular on the front and rear. This collar 52 is provided for resting on the underside of a printed circuit board in order to place the conductor connection terminal 1 on a printed circuit board and to reduce the forces acting on the soldered connections at the soldered connection surfaces to the printed circuit board as much as possible.

Figur 16 zeigt die Leiteranschlussklemme 1 aus Figur 15 von der Vorderseite. Erkennbar ist, dass an der Vorderseite die Leitereinführungsöffnungen 5 eingebracht sind. Figure 16 shows the conductor terminal 1 Figure 15 from the front. It can be seen that the conductor insertion openings 5 are made on the front.

Wie in Figur 15 wird auch hier deutlich, dass der Verschlussdeckel 40 bündig in den Kragen 52 des Isolierstoffgehäuses 2 übergeht, sodass der Kragen 52 zusammen mit dem Verschlussdeckel 40 das Isolierstoffgehäuse 2 an der Unterseite abdeckt.As in Figure 15 it is also clear here that the sealing cover 40 merges flush into the collar 52 of the insulating material housing 2, so that the collar 52 together with the sealing cover 40 covers the insulating material housing 2 on the underside.

Figur 17 zeigt die Leiteranschlussklemme 1 aus Figur 10 in der Seiten-Schnittansicht mit zusätzlichem Betätigungswerkzeug 20. Das Betätigungswerkzeug 20 hat ein Griffteil 53, von dem ein Betätigungsfinger 24 abragt. Der Betätigungsfinger 24 ist als platten- bzw. stabförmiges Element mit rundem oder bevorzugt eckigem Querschnitt ausgebildet und zum Einführen in eine Betätigungsöffnung 19 ausgebildet. Der Betätigungsfinger 24 gelangt dann zwischen zwei Betätigungslaschen 13 eines Federkraftklemmanschlusses 3, um auf diese Weise die mit einem Paar von Betätigungslaschen 13 jeweils verbundenen Blattfederzungen 11 auseinander zu drücken und damit die durch die Blattfederzungen 11 gebildete Klemmstelle zum Anklemmen eines elektrischen Leiters zu öffnen. Figure 17 shows the conductor terminal 1 Figure 10 in the side sectional view with additional actuating tool 20. The actuating tool 20 has a grip part 53, from which an actuating finger 24 projects. The actuating finger 24 is designed as a plate or rod-shaped element with a round or preferably angular cross section and is designed for insertion into an actuating opening 19. The actuating finger 24 then passes between two actuating tabs 13 of a spring-loaded terminal connection 3, in order in this way to press apart the leaf spring tongues 11, which are respectively connected to a pair of actuating tabs 13, and thus to open the clamping point formed by the leaf spring tongues 11 for clamping an electrical conductor.

Im Übrigen kann auf die Ausführungen zu Figur 10 verwiesen werden. Deutlich wird jedenfalls, dass die Unterseite der Leiteranschlussklemme 1 durch den Verschlussdeckel 40 abgedeckt ist.For the rest, can refer to the explanations Figure 10 to get expelled. In any case, it becomes clear that the underside of the conductor connection terminal 1 is covered by the closure cover 40.

Figur 18 zeigt die zweite Ausführungsform der Leiteranschlussklemme 1 gemäß Figur 14 nunmehr in zwei-poliger Ausführungsform. Hier kann im Wesentlichen wieder auf die Ausführungen zu Figur 14 verwiesen werden. Bei dieser zwei-poligen Leiteranschlussklemme 1 sind zwei durch jeweils eine zwischenliegende Zwischenkammer voneinander räumlich getrennte Federkraftklemmanschlüsse 3 mit jeweils zugeordneten Leitereinführungsöffnungen 5 im Isolierstoffgehäuse 2 vorgesehen. Figure 18 shows the second embodiment of the conductor terminal 1 according to Figure 14 now in two-pole embodiment. Here you can essentially refer to the explanations Figure 14 to get expelled. In this two-pole conductor connection terminal 1, two spring-loaded terminal connections 3, each spatially separated from one another by an intermediate intermediate chamber, are provided, each with associated conductor insertion openings 5 in the insulating-material housing 2.

Figur 19 zeigt eine Ausführungsform dieser Leiteranschlussklemme 1 in der ein-poligen Variante. Dabei ist nur ein einziger Federkraftklemmanschluss 3 vorhanden, der in eine Aufnahmeöffnung des Isolierstoffgehäuses 2 eintaucht, die durch den Verschlussdeckel 40 abgedeckt wird. Figure 19 shows an embodiment of this conductor terminal 1 in the single-pole variant. In this case, there is only a single spring-loaded terminal connection 3, which plunges into a receiving opening of the insulating material housing 2, which is covered by the closure cover 40.
