The contact bridge arrangement consists of fixed contact pieces (11, 12) and contact bridge (5) which can be brought into work connection with it and which is guided in a window (3, 4) of a contact bridge support (2) in the direction of the fixed contact pieces (11, 12) so as to be displaceable under spring force, The spring support is provided via a slide (13) which is supported on the parts fixed to the housing in the active position and is lifted from a stop (9) in the window (3) of the contact bridge support (2) and which is located between a spring plate (8) and the stop (9). in the window (3) of the contact bridge carrier (2) from the outside of the contact bridge arrangement can be inserted transversely to the spring loading direction.

Description

Die Erfindung bezieht sich auf eine Kontaktbrückenanordnung mit Festschaltstücken und mit diesen in Wirkverbindung bringbarer Kontaktbrücke, die in einem Fenster eines Kontaktbrückenträgers in Richtung auf die Festschaltstücke federkraftbelastet verschiebbar geführt ist und wobei die Federabstützung über ein in der Wirkstellung sich an gehäusefesten Teilen abstützendes, von einem Anschlag im Fenster des Kontaktbrückenträgers abgehobenes Abstützungsteil erfolgt.The invention relates to a contact bridge arrangement with fixed contact pieces and with this contact bridge which can be brought into operative connection, which is guided in a window of a contact bridge support in the direction of the fixed contact pieces in a spring-loaded manner and wherein the spring support is supported by a stop in the active position on parts fixed to the housing support part lifted off in the window of the contact bridge support.

Bei einer bekannten Kontaktbrückenanordnung der obengenannten Art (DT-AS 1 300 611) ist es, um das Abstützungsteil mit den gehäusefesten Teilen in Eingriff bringen zu können, notwendig, das Gehäuse zweizuteilen bzw. die festen Schaltstücke U-förmig derart auszubilden, daß sie mit einem U-Schenkel mit dem Abstützungsteil in Verbindung kommen. Bei diesen bekannten Anordnungen ist ein erheblicher Aufwand bei der Montage der Geräte zu treiben. Durch die vorliegende Erfindung soll eine Anordnung der obengenannten Art geschaffen werden, die eine automatengerechte Montage ermöglicht und einfach im Aufbau ist. Dies wird bei einer Anordnung der obengenannten Art dadurch erreicht, daß das Abstützungsteil ein Schieber ist, der zwischen einem Federteller und dem Anschlag . im Fenster des Kontaktbrückenträgers von der Außenseite der Kontaktbrückenanordnung quer zur Federbelastungsrichtung einschiebbar ist. Das Trennen von Federteller und Anschlag im Fenster erfolgt selbsttätig, wenn Anschlag und Schieber schräge Anlaufflächen haben. Ein automatisches Anheben des Federtellers und damit ein Spannen der Feder sowie das Verhindern des falschen Einsetzens des Schiebers wird gewährleistet, wenn die gehäusefesten Teile in Einschubrichtung steigend angeordnet und der Schieber mit einem dem Steigungsunterschied entsprechend hohen Ausgleichsansatz versehen ist. Der Einschubvorgang wird weiterhin vereinfacht, wenn auch das in Einschubrichtung erste gehäusefeste Teil als auch der Ausgleichsansatz schräge Anlaufflächen haben.In a known contact bridge arrangement of the type mentioned above (DT-AS 1 300 611), in order to be able to bring the support part into engagement with the housing-fixed parts, it is necessary to divide the housing into two parts or to form the fixed contact pieces in a U-shape in such a way that they are formed with a U-leg come into contact with the support part. In these known arrangements, considerable effort is required to assemble the devices. The present invention is intended to provide an arrangement of the above-mentioned type which is automated fair installation and easy to set up. This is achieved in an arrangement of the type mentioned above in that the support part is a slide which is between a spring plate and the stop. can be inserted transversely to the spring loading direction in the window of the contact bridge carrier from the outside of the contact bridge arrangement. The spring plate and the stop in the window are separated automatically if the stop and slide have sloping contact surfaces. An automatic lifting of the spring plate and thus tensioning of the spring as well as preventing the slider from being inserted incorrectly is ensured if the parts fixed to the housing are arranged so as to rise in the direction of insertion and the slider is provided with a compensation approach that is corresponding to the difference in pitch. The insertion process is further simplified if the part fixed to the housing in the insertion direction as well as the compensation shoulder also have sloping contact surfaces.

Anhand der Zeichnung wird ein Ausführungsbeispiel gemäß der Erfindung beschrieben und die Wirkungsweise näher erläutert.An exemplary embodiment according to the invention is described with reference to the drawing and the mode of operation is explained in more detail.

Das in der Zeichnung dargestellte Schaltgerät besteht aus dem in dem Gehäuse 1 verschiebbar geführten Kontaktbrückenträger 2, der mit Fenstern 3 und 4 versehen ist, in dem Kontaktbrücken 5 verschiebbar entgegen der Kraft der Federn 6 geführt sind. Die Federn 6 stützen sich über die Federteller 7 an den Kontaktbrücken 5 einerseits ab und liegen über die Federteller 8 an einem Anschlag 9 bzw. 10 des Fensters 3 bzw. 4 an. Die in der Fig. 1 oben liegende Kontaktbrücke 5 arbeitet mit den Festschaltstücken 11 als Öffnerkontakt und mit den Festschaltstücken 12 arbeitet die Kontaktbrücke 5, die im Fenster 4 verschiebbar geführt ist, als Schließerkontakt zusammen. Um einen im wesentlichen günstigeren Kraftbedarf und eine gleichmäßige Kraftverteilung bei Bewegung des Kontaktbrückenträgers 2 über den gesamten Schaltweg zu erreichen, wird eine sogenannte Öffnerabstützung vorgesehen, die aus dem Schieber 13, der zwischen den Anschlag 9 im Kontaktbrückenfenster 4 und den Federteller 8 eingeschoben wird, besteht. In Fig. 1 ist der Schieber bereits zur Anlage am Federteller 8 gebracht; in Fig. 2 ist er in die Betriebslage eingeschoben. Um das Einschieben zu erleichtern, sind an dem Anschlag 9 und dem Schieber 13 schräge Anlaufflächen 14 bzw. 15. Die gehäusefesten Teile, an denen sich der Schieber 13 abstützt, tragen die Bezugszeichen 16 bzw. 17 und sind treppenförmig angeordnet, d.h. in Einschubrichtung steigend ist die in der Zeichnung links liegende Abstützungsfläche tiefer als die rechts liegende. Die Steigung ist derart vorgesehen, daß, nachdem der Federteller 8 von dem Anschlag 9 abgehoben ist und der Schieber mit seiner Stärke zwischen beiden Teilen eingedrungen ist, die Anlauffläche 15 passend am Abstützungsteil 17 anliegt und hiernach wird der Schieber 13 weiter angehoben. Ein Ausgleichsansatz 18 am Schieber 13 kommt zur Auflage am Teil 16. Zum besseren Einführen dienen auch hier wieder schräge Flächen 19 bzw. 20 am Schieber 13 bzw. am Teil 16.The switching device shown in the drawing consists of the contact bridge carrier 2, which is displaceably guided in the housing 1 and is provided with windows 3 and 4, in which contact bridges 5 are guided displaceably against the force of the springs 6. The springs 6 are supported by the spring plates 7 on the contact bridges 5 on the one hand and rest on the spring plates 8 against a stop 9 or 10 of the window 3 or 4. The contact bridge 5 located at the top in FIG. 1 works with the fixed contact pieces 11 as a break contact and with the fixed contact pieces 12 the contact link 5, which is displaceably guided in the window 4, works together as a make contact. In order to achieve a substantially cheaper power requirement and a uniform force distribution when the contact bridge support 2 moves over the entire switching path, a so-called opener support is provided, which consists of the slide 13, which is inserted between the stop 9 in the contact bridge window 4 and the spring plate 8 . In Fig. 1, the slide is already brought to rest on the spring plate 8; in Fig. 2 it is inserted into the operating position. In order to facilitate insertion, sloping contact surfaces 14 and 15 are provided on the stop 9 and the slide 13. The parts fixed to the housing on which the slide 13 is supported bear the reference symbols 16 and 17 and are arranged in a step-like manner, i.e. Rising in the direction of insertion, the support surface on the left in the drawing is deeper than that on the right. The slope is provided such that, after the spring plate 8 is lifted off the stop 9 and the slide has penetrated with its strength between the two parts, the contact surface 15 fits snugly against the support part 17 and then the slide 13 is raised further. A compensating shoulder 18 on the slide 13 comes to rest on the part 16. For better insertion, inclined surfaces 19 and 20 on the slide 13 and on the part 16 are also used here again.

Die spezielle Ausführung des Schiebers 13 ist aus den Fig. 4 bis 6 zu ersehen, auf die hier verwiesen wird. Der Schieber 13 hat im Bereich des Ausgleichsansatzes 18 Ansätze 21, die in nutenförmige Ausnehmungen 22 im Gehäuse 1 im eingeschobenen Zustand des Schiebers 13 eingreifen. Die Ansätze 21 sind derart asymmetrisch angeordnet, daß der Schieber 13 nur in der aus der Zeichnung ersichtlichen Lage einschiebbar ist. Ein Anschlag 23 begrenzt die Einschubbewegung des Schiebers 13.The special design of the slide 13 can be seen from FIGS. 4 to 6, to which reference is made here. The slide 13 has in the region of the compensating projection 18 projections 21 which engage in groove-shaped recesses 22 in the housing 1 when the slide 13 is inserted. The lugs 21 are arranged asymmetrically such that the slider 13 can only be inserted in the position shown in the drawing. A stop 23 limits the insertion movement of the slide 13.

Es ist also ersichtlich, daß durch den erfindungsgemäßen Schieber eine Offnerabstützung geschaffen wurde, die auf einfache Weise eine relativ hohe Vorspannung erlaubt, ohne hierbei den Kontaktbrückentrkger in Extremstellung verschieben zu müssen und ohne die gehäusefesten Teile 16 und 17 entfernen zu können, mit einem geteilten Gehäuse arbeiten zu müssen. Die erfindungsgemäße Anordnung eignet sich besonders zur Montage durch einen Automaten und zum anderen ist derSchieber nur in einer Stellung einschiebbar, so daß ein falsches Einsetzen generell verhindert ist.It can thus be seen that an opener support was created by the slide according to the invention, which allows a relatively high preload in a simple manner, without having to move the contact bridge support to the extreme position and without being able to remove the parts 16 and 17 fixed to the housing, with a divided housing to have to work. The arrangement according to the invention is particularly suitable for assembly by an automatic machine and, on the other hand, the slide can only be inserted in one position, so that incorrect insertion is generally prevented.
