Description

Die Erfindung betrifft ein Klemmbrett für elektrische oder elektronische Geräte, z.B. Überstrom-Schutzschalter mit den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a clipboard for electrical or electronic devices, e.g. Overcurrent circuit breaker with the features of the preamble of claim 1.

Derartige Geräte bestehen in der Regel aus einer Isolierstoff-Grundplatte mit mindestens einer Einsteckausnehmung zum Einführen und/oder Festklemmen von aus einem Geräte-Unterteil hervorstehenden Kontaktzungen, wobei in jeder Einsteckausnehmung mindestens eine Kontaktfeder zur Beaufschlagung der Kontaktzungen angeordnet und mit Anschlußmitteln zum Anschluß von Leitungen verbunden ist, die in der Regel aus der Rückseite des Klemmbrettes herausstehen.Such devices generally consist of an insulating base plate with at least one insertion recess for inserting and / or clamping projecting tongues protruding from a lower part of the device, wherein at least one contact spring is arranged in each insertion recess to act on the contact tongues and connected to connecting means for connecting lines that usually protrude from the back of the clipboard.

Der Erfindung liegt die Aufgabe zugrunde, ein Klemmbrett insbesondere für Sicherungen und Überstrom-Schutzschalter derart auszugestalten, daß Geräte unterschiedlicher Bauart, insbesondere mit einer unterschiedlichen Anordnung von Kontakt- und Halterungselementen mit dem Klemmbrett in funktionsmäßige Verbindung gebracht werden können. Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.The invention has for its object to design a clipboard in particular for fuses and overcurrent circuit breakers such that devices of different types, in particular with a different arrangement of contact and mounting elements can be brought into functional connection with the clipboard. This object is achieved by the characterizing features of claim 1.

Durch die Anordnung der Ausnehmungen, die Anbringung der Kontakte in der Ausnehmung, die Anordnung der Schraubhülsen sowie die Anordnung der im Mittelbereich der Einsteckausnehmungen befindlichen Federhaken sind Montage und ein funktionelles elektrisches Zusammenwirken des Klemmbretts mit Sicherungen und Überstrom-schutzschaltern unterschiedlicher Ausführung möglich. Zum einen können relativ schwere Geräte durch Verschraubung ihrer Kontaktelemente in bzw. auf den Schraubhülsen befestigt und elektrisch kontaktiert werden. Weiterhin ist die Befestigung von kleinen Sicherungsautomaten dadurch möglich, daß sie mit einem Fußteil in die Einsteckausnehmung eingeführt werden, dort mit aus dem Fußteil herausstehenden Kontaktzungen zwischen die federnden Kontaktschenkel eingreifen und zur Befestigung mit Rastnasen hinter den Federhaken verrasten. Dadurch werden derartige Sicherungsautomaten in guter elektrischer und mechanischer Verbindung mit dem Klemmbrett gehalten. `The arrangement of the recesses, the attachment of the contacts in the recess, the arrangement of the screw sleeves and the arrangement of the spring hooks located in the central region of the insertion recesses enable assembly and a functional electrical interaction of the clipboard with fuses and overcurrent protection switches of different designs. On the one hand, relatively heavy devices can be attached and electrically contacted by screwing their contact elements into or on the screw sleeves. Furthermore, the attachment of small automatic circuit breakers is possible in that they are inserted with a foot part into the insertion recess, engage there with contact tongues protruding from the foot part between the resilient contact legs and lock behind the spring hooks for fastening with locking lugs. As a result, such automatic circuit breakers are kept in good electrical and mechanical connection with the clipboard. `

Schließlich sind auch noch einfache Schmelzsicherungseinsätze in Verbindung mit dem Klemmbrett verwendbar, die im wesentlichen aus einem mehr oder weniger ganz in die Einsteckausnehmung eintauchenden Sicherungskörper bestehen, aus dem beidendseitig zwei Konaktzungen herausstehen. Eine Verrastung einer derartigen Schmelzsicherung mit den Federhaken ist aufgrund der geringen Masse derartiger Schmelzsicherungseinsätze nicht notwendig.Finally, simple fuse links can also be used in connection with the clipboard, which essentially consist of a more or less fully immersed fuse body from which two contact tongues protrude on both sides. Locking such a fuse with the spring hook is not necessary due to the low mass of such fuse links.

Durch die stark erweiterten Einsatzmöglichkeiten eines derartigen Klemmbrettes wird die Lagerhaltung für den Monteur derartiger Klemmbretter stark verringert. Zudem ist es möglich, bei bereits montierten Klemmbrettern je nach Art der elektrischen Verbraucher unterschiedliche Sicherungstypen auf einem Klemmbrett nebeneinander oder - falls erforderlich - auch zeitlich nacheinander zu verwenden, falls einmal ein Verbraucher ausgetauscht wird.Due to the greatly expanded possible uses of such a clipboard, storage for the installer of such clipboards is greatly reduced. In addition, it is possible to have different types of fuse on a clipboard in addition to clipboards already installed, depending on the type of electrical consumer to use each other or - if necessary - one after the other if a consumer is ever replaced.

Durch Anspruch 2 wird eine dauerhafte, funktionssichere und platzsparende Anordnung der Kontaktelemente sowie deren gegenseitige elektrische Verbindung gelehrt. Insbesondere durch die winkelige Ausbildung der Kontaktfedern sowie deren Befestigung am Ende des einen Winkelschenkels wird ein gewisses Federverhalten erzielt, durch welches Beschädigungen beim Einstecken der Sicherungselemente vermieden und insbesondere auch Herstellungstoleranzen im Bereich der Einsteckausnehmungen ausgeglichen werden.Claim 2 teaches a permanent, reliable and space-saving arrangement of the contact elements and their mutual electrical connection. In particular, due to the angular design of the contact springs and their attachment to the end of the one angle leg, a certain spring behavior is achieved, by means of which damage when the securing elements are inserted is avoided and, in particular, manufacturing tolerances in the region of the insertion recesses are compensated for.

Anspruch 3 zielt auf eine einfache und funktionelle Befestigungsart der Anschlußmittel ab, die von der Rückseite des Klemmbretts abstehen. Durch die Art der Befestigung können diese mit einem einfachen Preßhub zusammen mit der zugeordneten Kontaktfeder und gegebenenfalls weiteren Anschlußelementen dadurch befestigt werden, daß das rückwärtige Ende der Schraubhülse in Form einer Umbördelung gestaucht wird.Claim 3 aims at a simple and functional type of attachment of the connection means, which protrude from the back of the clipboard. Due to the type of fastening, these can be fastened with a simple press stroke together with the associated contact spring and, if appropriate, further connecting elements in that the rear end of the screw sleeve is compressed in the form of a flange.

Durch das Kennzeichen des Anspruchs 5 können bei der Montage die Kontaktfedern von unten in die Einstecköffnung hineingeschoben werden und liegen dann - unter Ausnutzung der oben erwähnten Eigenfederung - mit ihren Seitenkanten in Nuten der Seitenwandungen ein, wodurch sie eine zusätzliche Seitenführung erfahren.By the characterizing part of claim 5, the contact springs can be pushed into the insertion opening from below and are then - using the above-mentioned self-suspension - with their side edges in grooves of the side walls, whereby they experience an additional lateral guidance.

Durch Anspruch 6 ist zum einen sichergestellt, daß die die Kontaktseite bildende Oberseite der Schraubhülsen beim Befestigen der Kontaktfedern und Anschlußmittel durch einen Stanzvorgang nicht all zu tief in den Kunststoff hineingepreßt wird, woraus Ungenauigkeiten bei der Montage der zu verschraubenden Sicherungen oder gar eine Beschädigung des Klemmbretts entstehen können. Durch die relativ große Oberfläche der Hülsen aufgrund des Randes werden die in die Einschraubhülsen eingeschraubten Sicherungselemente mechanisch ausreichend abgestützt.Claim 6 ensures, on the one hand, that the upper side of the screw sleeves forming the contact side when fastening the contact springs and connecting means by a punching process is not too deep in the Plastic is pressed in, which can result in inaccuracies in the assembly of the fuses to be screwed or even damage to the clipboard. Due to the relatively large surface area of the sleeves due to the edge, the securing elements screwed into the screw-in sleeves are mechanically adequately supported.

Durch das Kennzeichen des Anspruches 8 wird die in den Schlitz einliegende Kontaktzunge auf ihren beiden Seiten nur punktuell beaufschlagt, wodurch ein ausreichender Kontaktdruck erzeugt werden kann. Die gewellte Form des Schlitzes wirkt sich auch vorteilhaft bei der Herstellung der Kontaktzungen aus, da diese trotz des Erfordernisses der punktförmigen Kontaktanlage durch einen einfachen Stanzvorgang hergestellt werden können. Durch das an sich bekannte Merkmal des Anspruches 9 können - wie bereits eingangs angedeutet - eine Vielzahl von gleichen und/oder unterschiedlichen Sicherungselementen je nach Bedarf auf ein und demselben Klemmbrett montiert werden.By the characterizing part of claim 8, the contact tongue lying in the slot is only acted upon selectively on both sides, whereby a sufficient contact pressure can be generated. The corrugated shape of the slot also has an advantageous effect in the production of the contact tongues, since, despite the requirement for the point-like contact system, these can be produced by a simple stamping process. Due to the known feature of claim 9 - as already indicated - a plurality of the same and / or different securing elements can be mounted on one and the same clipboard as required.

Ein Klemmbrett 1 für elektrische oder elektronische Geräte besteht im wesentlichen aus einer Isolierstoff-Grundplatte 2, in welcher sechs Einsteckausnehmungen 3 entlang der Mittellängsachse 4 der Grundplatte 2 angeordnet sind. Die Einsteckausnehmungen 3 haben einen langgestreckten Querschnitt und sind parallel nebeneinanderliegend derart angeordnet, daß ihre Längsachsen 5 rechtwinklig zur Mittellängsachse 4 liegen. In jeder Einsteckausnehmung 3 sind zwei Kontaktfedern 6 angeordnet, die mit als Flachstecker 7 ausgebildeten Anschlußmitteln elektrisch verbunden sind. Die Kontaktfedern sind bezüglich der Mittellängsachse 4 symmetrisch in den Einsteckausnehmungen 3 angeordnet und liegen zwischen den Längsenden 8 und Federhaken 10, die zur Verrastung von Überstrom-Schutzschaltern im Mittelbereich der Längserstreckung der Einsteckausnehmungen 3 im Bereich der Ausnehmungslängsseiten 9 angeordnet sind. Die Federrichtung 11 der Federhaken 10 verläuft dabei rechtwinklig zur Längsachse 5 der Einsteckausnehmung 3.A clipboard 1 for electrical or electronic devices essentially consists of an insulating base plate 2, in which six insertion recesses 3 are arranged along the central longitudinal axis 4 of the base plate 2. The insertion recesses 3 have an elongated cross section and are arranged parallel to one another in such a way that their longitudinal axes 5 lie at right angles to the central longitudinal axis 4. In each insertion recess 3, two contact springs 6 are arranged, which are electrically connected to connection means designed as flat plugs 7. The contact springs are arranged symmetrically with respect to the central longitudinal axis 4 in the insertion recesses 3 and lie between the longitudinal ends 8 and spring hooks 10, which are arranged in the region of the recess longitudinal sides 9 for latching overcurrent protection switches in the central region of the longitudinal extent of the insertion recesses 3. The spring direction 11 of the spring hook 10 runs at right angles to the longitudinal axis 5 of the insertion recess 3.

Im Bereich der Längsenden 8 sind außerhalb der Einsteckausnehmungen Schraubhülsen 12 angeordnet, die mit ihren Zentren 13 auf der Längsachse 5 der zugeordneten Einsteckausnehmung 3 liegen und in die Isolierstoff-Grundplatte 2 durchgreifenden Bohrungen 14 derart befestigt sind, daß sie auf der Frontfläche 15 mit einem radial über die Schraubhülse überstehenden Rand 16 aufliegen und auf der Rückseite mit einer Umbördelung 17 fixiert sind.In the area of the longitudinal ends 8, screw sleeves 12 are arranged outside of the insertion recesses, the centers 13 of which lie on the longitudinal axis 5 of the associated insertion recess 3 and bores 14 penetrating into the insulating base plate 2 in such a way Stigt that they rest on the front surface 15 with a radially projecting over the screw sleeve edge 16 and are fixed on the back with a flange 17.

Die gegenseitige Befestigung und elektrische Verbindung von Schraubhülsen und zugeordneten Kontaktfedern bzw. Flachsteckern ist wie folgt vorgenommen: Sowohl Flachstecker 7 als auch Kontaktfedern 6 bestehen aus einem rechtwinklig abgebogenen Stanzteil. Bei den Kontaktfedern 6 ist der erste Winkelschenkel 20 zur Bildung von zwei federnden Kontaktschenkeln 21 etwa mittig geschlitzt und von der Rückseite 28 her in die zugehörige Einsteckausnehmung 3 eingeführt, die als das Klemmbrett 1 durchgreifende Ausnehmung ausgebildet ist. Der zweite Winkelschenkel 22 ist an seinem Schenkelende 23 mit einem Rundloch 24 versehen, durch welches das rückwärtige Ende 25 der zugeordneten Schraubhülse 12 hindü%rchsteht.The mutual fastening and electrical connection of screw sleeves and associated contact springs or tabs is carried out as follows: Both tabs 7 and contact springs 6 consist of a stamped part bent at right angles. In the case of the contact springs 6, the first angle leg 20 is slotted approximately in the middle to form two resilient contact legs 21 and is inserted from the rear 28 into the associated insertion recess 3, which is designed as a recess extending through the clipboard 1. The second angle leg 22 is provided at its leg end 23 with a round hole 24 through which the rear end 25 of the associated screw sleeve 12 protrudes.

Die Flachstecker 7 weisen an ihrem Befestigungsende 26 ebenfalls eine winklige Abbiegung 27 auf, die parallel zum zweiten Winkelschenkel 22 der Kontaktfedern 6 angeordnet ist und ebenfalls ein Loch hat, durch welches das rückwärtige Ende 25 der Schraubhülsen 12 hindurchsteht. Gegebenenfalls können noch weitere derartige Anschlußmittel in entsprechender Weise angeordnet und mit der zugeordneten Schraubhülse 12 verbunden sein. Die Flachstecker 7 stehen in Einsteckrichtung von der Rückseite 28 der Grundplatte 2 ab. Eine dauerhafte Befestigung und elektrische Verbindung zwischen Flachsteckern, Kontaktfedern und Schraubhülsen wird dadurch geschaffen, daß die Umbördelung erst nach Durchgreifen der Flachstecker-Befestigungsenden 26 vollzogen ist, wodurch die Befestigungsenden 26 bzw. die zweiten Winkelschenkel gleichsam als Beilagscheiben dienen. Abbiegungen 27 und zweite winkelschenkel 22 liegen in Nuten 29 ein, die in die Rückseite 28 der Grundplatte 2 eingebracht sind, wodurch die Nutseitenkanten zusätzlich fixiert sind. Die Nuten 29 verlaufen auf der Verbindungslinie der Zentren 13 der Schraubhülsen 12.The tabs 7 also have an angled bend 27 at their fastening end 26, which is arranged parallel to the second angle leg 22 of the contact springs 6 and also has a hole through which the rear end 25 of the screw sleeves 12 protrudes. If necessary, further connection means of this type can be arranged in a corresponding manner and connected to the assigned screw sleeve 12. The tabs 7 protrude from the back 28 of the base plate 2 in the direction of insertion. A permanent attachment and electrical connection between flat plugs, contact springs and screw sleeves is created in that the flanging is carried out only after reaching through the flat plug fastening ends 26, so that the fastening ends 26 and the second angle legs serve as washers, as it were. Bends 27 and second angle legs 22 lie in grooves 29 which are introduced into the rear 28 of the base plate 2, as a result of which the groove side edges are additionally fixed. The grooves 29 run on the connecting line of the centers 13 of the screw sleeves 12.

In den Seitenwandungen 30 der Einsteckausnehmungen 3 sind weitere Nuten 31 angeordnet, die zur Aufnahme der Kontaktfederschenkel-Seitenkanten 32 dienen.In the side walls 30 of the insertion recesses 3 further grooves 31 are arranged, which serve to receive the contact spring leg side edges 32.

Der zwischen den Kontaktschenkeln 21 der Kontaktfedern 6 liegende Schlitz 33 verläuft in einer Wellenlinie derart, daß eine Kontaktzunge 34 eines elektrischen Gerätes 40,41 von der einen Seite durch einen ersten Punktkontakt, von der anderen Seite durch zwei weitere Punktkontakte beaufschlagt und somit in einer Dreipunkthalterung gehalten wird.The slot 33 lying between the contact legs 21 of the contact springs 6 runs in a wavy line in such a way that a contact tongue 34 of an electrical device 40, 41 acts on one side through a first point contact and on the other side through two further point contacts and thus in a three-point holder is held.

Bei der in den Fig. 9 und 10 dargestellten Klemmbrett-Gerätekombination ist das Gerät 42 nicht in die Einsteckausnehmung 3 eingeführt, sondern mittels Kontaktlaschen 43 auf der Oberseite der Schraubhülsen 12 mittels Halteschrauben 44 verschraubt. Eine derartige Anordnung empfiehlt sich besonders bei Geräten, die zur Betätigung nicht nur einen axial wirksamen manuellen Druckknopfschalter 45 haben, sondern zusätzlich' mit einem zur Hilfsauslösung des Gerätes 42 vorgesehenen Kipphebel 46 versehen sind, bei dessen Betätigung seitlich wirksame Kräfte auf die Geräte/Klemmbrettkombination wirken.In the clipboard-device combination shown in FIGS. 9 and 10, the device 42 is not inserted into the insertion recess 3, but is screwed by means of contact tabs 43 on the top of the screw sleeves 12 by means of retaining screws 44. Such an arrangement is particularly recommended for devices that not only have an axially effective manual push-button switch 45 for actuation, but are additionally provided with a rocker arm 46 provided for auxiliary triggering of the device 42, when actuated laterally acting forces act on the device / clipboard combination .
