Description
Die Erfindung betrifft eine Anschluß- und Verbindungsklemme für mindestens zwei elektr. Leiter gemäß den Merkmalen des Oberbegriffs des Anspruches 1.The invention relates to a connection and Connection clamp for at least two electr. Head according to the characteristics of the The preamble of claim 1.
Solche Federkraftklemmen sind aus der DE 35 14 099 C2 bekannt. Sie sind dort als Verbindungsklemmen für zwei elektr. Leiter mit einer in sich steifen, aus einem Flachmaterial gefertigten Stromschiene vorgestellt, an deren Oberseite und an deren Unterseite jeweils eine Klemmstelle für je einen anzuschließenden elektr. Leiter gebildet sind. Die anzuschließenden elektr. Leiter kontaktieren die Stromschiene direkt, so daß zwischen den Klemmstellen kürzeste Stromwege durch die flache Stromschiene hindurch gewährleistet sind. Das gilt insbesondere dann, wenn die Klemmstellen auf der Oberseite und auf der Unterseite der Stromschiene unmittelbar einander gegenüberliegen.Such spring clips are from the DE 35 14 099 C2 known. You are there as Connection terminals for two electr. ladder with a stiff one, made of a flat material manufactured conductor rail presented, on the top and on the bottom one clamping point each for one to be connected electr. Heads are formed. The electr. ladder contact the power rail directly, so that shortest between the terminal points Current paths through the flat conductor rail are guaranteed. That applies especially when the nips on the top and on the bottom the busbar are directly opposite each other.
Ein wesentliches Konstruktionsmerkmal dieser Art von Klemmen ist, daß beide Klemmstellen die Federkraft nur einer, d.h. ein- und derselben Klemmfeder nutzen, die als sogenannte Käfigzugfeder mit der unteren Kante der Fensterausnehmung in ihrem Klemmschenkel die Klemmstelle an der Unterseite der Stromschiene bildet und mit ihrem in Richtung der Stromschiene sich erstreckenden Anlageschenkel die Klemmstelle an der Oberseite der Stromschiene mit der notwendigen Federkraft beaufschlagt.An essential design feature this type of clamps is that both The spring force is clamped by only one, i.e. use one and the same spring clip as a so-called cage tension spring with the lower one Edge of the window recess in its clamping leg the nip at the bottom the busbar forms and with her in Direction of the busbar extending Contact the clamping point on the top the busbar with the necessary Spring force applied.
Die an die Klemmen dieser Art anzuschließenden elektr. Leiter können Drahtleiter, runde Stifte, flache Steckzungen o.dergl. sein. Die Stromschiene der Anschluß- und Verbindungsklemme kann länger oder kürzer ausgeführt sein, je nachdem ob sie nur die beiden Klemmstellen einer Zwei-Leiter-Verbindungsklemme miteinander verbinden soll oder ob sie als weiterführende Stromschiene die elektr. Verbindung zu anderen elektrischen oder elektronischen Bauelementen, Klemmenteilen, Geräten o.dergl. herstellen soll.The ones to be connected to the terminals of this type electr. Conductors can be wire conductors, round pins, flat tabs or the like his. The track the connection and connection terminal can be made longer or shorter, depending after seeing only the two nips a two-wire connection terminal together should connect or whether they as advanced Track the electr. Connection to others electrical or electronic components, Terminal parts, devices or the like. produce should.
Im letzteren Fall treten bei den bekannten Anschluß- und Verbindungsklemmen gewisse Handhabungsnachteile auf, die dadurch bedingt sind, daß die Klemmstellen, die von derselben Klemmfeder mit Federkraft beaufschlagt sind, aus entgegengesetzten Leiteranschlußrichtungen mit elektr. Leitern verdrahtet bzw. belegt werden müssen. Das behindert die konstruktive Weiterführung der Stromschiene, die in der Praxis oftmals in einer der beiden Leiteranschlußrichtungen erfolgen soll, beispielsweise wenn die Anschluß- und Verbindungsklemme der vorgenannten Art integrierter Bestandteil eines elektrischen oder elektronischen Moduls, einer Reihenklemme mit diversen anderen Leiteranschlüssen oder eines elektr. Gerätes sein soll.In the latter case occur in the known Connection and connection terminals certain Handling disadvantages that result are that the nips that of the same clamping spring with spring force are from opposite conductor connection directions with electr. Wired conductors or must be documented. The hinders constructive continuation the busbar, which in practice often in one of the two conductor connection directions should take place, for example if the connection and connecting clamp of the aforementioned Kind of an integral part of an electrical or electronic module, a terminal block with various other conductor connections or an electr. Device.
Aufgabe der Erfindung ist es, die Anschluß- und Verbindungsklemme des im Oberbegriff des Anspruches 1 definierten Typs so weiterzuentwickeln, daß sie konstruktiv einfacher in andere elektrische oder elektronische Bauelemente zu integrieren ist oder an diese mit ihrer Stromschiene anzubinden ist, ohne daß dabei die platzsparende Bauweise und die Kostenvorteile einer Anschluß- und Verbindungsklemme gemindert werden, die mit nur einer Klemmfeder sowohl eine Klemmstelle an der Unterseite, als auch eine Klemmstelle an der Oberseite einer Stromschiene mit der notwendigen Federkraft versorgt.The object of the invention is to connect the and connecting terminal of the in the preamble of To further develop claim 1 of defined type that they're constructively easier in other electrical or electronic components is to be integrated or to this can be connected to their track without that the space-saving design and the Cost advantages of a connection and connection terminal be mitigated with just one Clamping spring both a clamping point on the Bottom, as well as a clamping point the top of a track with the necessary spring force supplied.
Diese Aufgabe wird bei der Anschluß- und Verbindungsklemme des vorgenannten Typs durch die im Kennzeichen des Anspruches 1 genannten Merkmale gelöst.This task is in connection and Connection clamp of the aforementioned type by the in the characterizing part of claim 1 mentioned features solved.
Nach der Lehre der Erfindung ist vorgeschlagen, alle elektr. Leiter aus derselben Richtung (und zwar entgegen der Erstreckungsrichtung des Anlageschenkels der Klemmfeder) durch eine entsprechend groß bemessene Fensterausnehmung in dem Klemmschenkel der Klemmfeder den jeweiligen Klemmstellen an der Oberseite und an der Unterseite der Stromschiene zuzuführen.According to the teaching of the invention, it is proposed all electr. Ladder from the same direction (and that against the direction of extension of the contact leg of the clamping spring) a correspondingly large window recess in the clamping leg of the clamping spring the respective terminal points on the Top and bottom of the track feed.
Durch diese gleichgerichtete Leitereinführung aller anzuschließenden Leiter ist bei Anschluß- und Verbindungsklemmen dieses Typs erstmals eine für alle Klemmstellen gemeinsame Frontbedienungsseite geschaffen worden, so daß die gegenüberliegende Rückseite der Klemme frei bleibt, um dort jede gewünschte Art und Richtung der Weiterführung der Stromschiene und/oder die Anordnung einer sonstigen weiterführenden Verbindung (z.B. in Form einer weiterführenden Steckverbindung oder eines weiterführenden Leiteranschlußelementes) zu anderen Bauelementen, Geräten o.dergl. vornehmen zu können. Die erfindungsgemäße Anschluß- und Verbindungsklemme ist dadurch universeller einsetzbar und besser in andere elektrische Baueinheiten integrierbar.Through this rectified conductor entry all conductors to be connected are and connection terminals of this type for the first time a common one for all terminal points Front operating side has been created, so that the opposite back of the clamp remains free to order any type and Direction of continuation of the conductor rail and / or the arrangement of another further Connection (e.g. in the form of a continuation Plug connection or a further Conductor connecting element) to others Components, devices or the like make to can. The connection and This makes the connecting clamp more universal applicable and better in other electrical Units can be integrated.
Bei der erfindungsgemäßen Anschluß- und Verbindungsklemme ist die Klemmstelle an der Oberseite der Stromschiene permanent für eine Leitereinführung zugänglich. Das ist die Folge einer entsprechend groß bemessenen Fensterausnehmung in dem Klemmschenkel der Klemmfeder, die immer die Durchführung eines Leiters erlaubt, unabhängig davon, ob die Klemmstelle an der Unterseite der Stromschiene in bekannter Weise durch Niederdrücken des Klemmschenkels der Klemmfeder geöffnet oder nach Belegung mit einem elektr. Leiter geschlossen oder im nicht-belegten Zustand, d.h. ohne Leiter geschlossen ist. Immer bleibt der Leitereinführungstrichter für die obere Klemmstelle frei zugänglich, der nach der Lehre der Erfindung zwischen der Oberseite der Stromschiene und dem von dieser hinwegweisend abgebogenen freien Ende des Anlageschenkels der Klemmfeder gebildet ist. In the connection and The connecting terminal is at the terminal point the top of the track permanently accessible for a conductor entry. The is the consequence of a correspondingly large Window recess in the clamping leg the clamping spring that always the Conducting a ladder allowed, independently whether the nip is on the bottom of the busbar in known Way by depressing the Clamping leg of the clamping spring opened or after allocation of an electr. ladder closed or in the unoccupied state, i.e. is closed without a ladder. always remains the lead entry funnel for the upper terminal point freely accessible, the according to the teaching of the invention between the Top of the track and that of this pioneering free turn End of the contact leg of the clamping spring is formed.
Gemäß Anspruch 2 sieht eine vorteilhafte Ausführungsform der Erfindung vor, daß an der Oberseite der Stromschiene zwei Klemmstellen für elektr. Leiter dadurch geschaffen werden, daß das freie Ende des Anlageschenkels durch einen etwa mittigen Längsschnitt in Erstreckungsrichtung des Anlageschenkels in zwei Blattfeder-Anlageschenkel unterteilt ist, die jeweils für sich eine obere Klemmstelle gegen die Oberseite der Stromschiene bilden. Hierdurch wird erreicht, daß die beiden unmittelbar benachbarten Klemmstellen an der Oberseite der Stromschiene auch als Stützpunkt für einen ankommenden und einen abgehenden elektr. Leiter oder für eine Verkettung von Brückungsleitern zu benachbart angeordneten Klemmen dieses Typs genutzt werden können.According to claim 2 sees an advantageous Embodiment of the invention before that at the top of the track two Terminal points for electr. Head through it be created that the free end of the Plant leg by an approximately central Longitudinal section in the direction of extension of the Contact leg in two leaf spring contact legs is divided, each for an upper nip against the Form the top of the track. Hereby is achieved that the two immediately adjacent terminal points the top of the track also as Base for one arriving and one outgoing electr. Head or for one Linking of bridge conductors to neighboring arranged clamps this Type can be used.
Zur Verstärkung der Leiterhaltekräfte in den Klemmstellen an der Oberseite der Stromschiene ist gemäß Anspruch 3 vorgesehen, daß die trichterbildenden Abbiegungen des Anlageschenkels der Klemmfeder oder der aus dem Anlageschenkel gebildeten beiden Blattfeder-Anlageschenkel jeweils Ausstanzungen aufweisen, die im Bereich der oberen Klemmstellen scharfkantige Klemmkanten bilden. To strengthen the conductor holding forces in the clamping points on the top of the Busbar is provided according to claim 3, that the funnel-forming turns the contact leg of the clamping spring or the formed from the investment leg two Leaf spring contact legs each punched out have the range of upper clamping points sharp-edged clamping edges form.

Diese Klemmfeder ist auf die in Fig. 3 dargestellte
Stromschiene 24 aufgesetzt derart,
daß (wie dies Fig. 5 zeigt) die Fensterausnehmung
23 das freie Ende 25 der Stromschiene
übergreift, d.h. das freie Ende der Stromschiene
erstreckt sich durch die Fensterausnehmung
hindurch. Dabei liegen die Blattfeder-Anlageschenkel
20 und 21 jeweils auf
den äußeren Aufkantungen 26 und 27 der Stromschiene
auf, die durch diese Aufkantungen
gemuldet ist, und zwar zum Zwecke der Aufnahme

Zum Einsetzen des unteren Leiters 16 in
die sogenannte untere Klemmstelle der
Klemme (siehe hierzu Fig. 2) muß vorher
die untere Klemmstelle geöffnet werden.
Das erfolgt in bekannter Weise dadurch,
daß die Spitze eines Schraubendrehers
(nicht dargestellt) in die Betätigungsöffnung
14 des Isolierstoffgehäuses axial
eingeschoben wird, wodurch der Klemmschenkel
22 der Klemmfeder niedergedrückt
wird, so daß der elektr. Leiter 16 in die
dann offene Klemmstellen eingeführt werden
kann, die zwischen der unteren Kante der
Fensterausnehmung 23 des Klemmschenkels 22
(siehe hierzu Fig. 4) und der Unterseite
der Stromschiene gebildet ist.To insert the
Fig. 2 verdeutlicht, daß alle elektr. Leiter 15
und 16 aus derselben Leitereinführungsrichtung
in die Klemmstellen eingeführt werden, die
oberhalb und unterhalb der Stromschiene 24
gebildet sind. Dadurch bleibt das gegenüberliegende
Ende 34 der Stromschiene vollständig
frei, um dort jede gewünschte Art und Richtung
der Weiterführung der Stromschiene vorzunehmen
und/oder andere elektr. Anschluß- und Verbindungselemente
anzuordnen. Fig. 2 illustrates that all electrical.

Ausführungsform einer Stromschiene und
einer Klemmfeder, bei der der Anlageschenkel
35 in einem Stück breitflächig
ausgebildet ist und demzufolge nur eine
obere Klemmstelle zwischen dem Anlageschenkel
und der Oberseite der Stromschiene
36 gebildet ist. Diese Ausführungsform
eignet sich gut zum Einstecken von
elektr. Leitern in Form von flachen
Steckzungen, wie diese z.B. an Brückungskämmen
üblich sind und benutzt werden,
um Querbrückungen zwischen einander

- Clip according to claim 1,
characterisedin that the free end of the gripping portion is divided, by means of a substantially central longitudinal cut (19) in the extension direction of the gripping portion, into two leaf spring gripping portions (20, 21), which each form per se an upper clamping location against the upper side of the current-collecting rail. - Clip according to claim 1 or 2,
characterisedin that the funnel-forming bent portions of the gripping portion or of the two leaf spring gripping portions, formed from the gripping portion, each have punched-out portions (37, 38) which form sharp-edged clamping edges in the region of the upper clamping locations. - Clip according to one of claims 1 to 3,
characterisedin that the upper side of the current-collecting rail is recessed, preferably by placing the external edge regions (26, 27) of the current-collecting rail upright, in order to accommodate and guide the additional electrical conductor or conductors. - Clip according to one of the preceding claims,
characterisedin that the free end of the gripping portion, or of the two leaf-spring gripping portions formed from the gripping portion, extends or extend through the opening (23) of the clamping portion (22) of the clamping spring (17),and the upper clamping location or respectively the upper clamping locations is or are positioned internally of or in the extension direction of the gripping portion towards the opening of the clamping portion.
