Alternativ können auch mehrere Kontaktfederbleche übereinander gelegt und zu einem Paket verbunden werden.A contact spring for a bistable relay for switching high currents is described, the actual contact spring being connected in parallel with at least one strand which receives a portion of the currents.

Description

Die Erfindung betrifft eine Kontaktfeder für ein bistabiles Relais zum Schalten hoher Ströme.The invention relates to a contact spring for a bistable relay for switching high currents.

Beim Schalten hoher Ströme, beispielsweise in der Größenordnung von 30 bis 40 Ampere, tritt das Problem auf, daß die eigentliche Kontaktfeder die hohen Ströme nicht mehr ohne weiteres aufnehmen kann, wenn die Kontaktfeder leicht beweglich sein soll. Für die Aufnahme der hohen Ströme müsste man nämlich ihren Querschnitt eigentlich entsprechend vergrößern, was naturgemäss mit einer fühlbaren Versteifung der Kontaktfeder einhergeht.When switching high currents, for example in the order of 30 to 40 amperes, the problem arises that the actual contact spring can no longer easily absorb the high currents if the contact spring is to be easily movable. To absorb the high currents, one would actually have to increase their cross-section accordingly, which naturally goes hand in hand with a noticeable stiffening of the contact spring.

Hier setzt die Erfindung ein, der die Aufgabe zugrunde liegt, eine Kontaktfeder für ein bistabiles Relais zum Schalten hoher Ströme vorzuschlagen, die einerseits leicht beweglich ist und andererseits es gestattet, hohe Ströme zu - schatten.This is where the invention comes in, which is based on the object of proposing a contact spring for a bistable relay for switching high currents, which on the one hand is easy to move and on the other hand allows high currents to be shadowed.

Die Erfindung geht bei einem Aspekt aus von einer Kontaktfeder für ein bistabiles Relais zum Schatten hoher Ströme, die aus einem länglichen, einstückigen Metallblech mit einem Einspannende und einem Kontaktende besteht, zwischen denen eine Biegezone ausgebildet ist Zur Lösung der erwähnten Aufgabe ist bei diesem Aspekt die Erfindung dadurch gekennzeichnet, daß wenigstens eine Litze aus stromleitendem Material vorgesehen ist, deren Ende stromleitend mit dem Einspannende bzw. mit dem Kontaktende des Metallblechs verbunden ist.In one aspect, the invention is based on a contact spring for a bistable relay for shading high currents, which consists of an elongated, one-piece metal sheet with a clamping end and a contact end, between which a bending zone is formed Invention characterized in that at least one strand of current-conducting material is provided, the end of which is connected in a current-conducting manner to the clamping end or to the contact end of the metal sheet.

Im Betrieb teilen sich somit die Ströme zwischen dem eigentlichen Metallblech und der oder den Litzen auf. Diese sind leicht beweglich und erhöhen nicht fühlbar oder nachteilig die leichte Biegbarkeit des Metallstücks (Metallblechs), welches daher entsprechend den mechanischen Anforderungen , insbesondere der leichten Biegbarkeit, gestaltet werden kann.In operation, the currents are thus divided between the actual metal sheet and the strand or strands. These are easily movable and do not noticeably or disadvantageously increase the easy bendability of the metal piece (metal sheet), which can therefore be designed in accordance with the mechanical requirements, in particular the easy bendability.

Der andere Aspekt der Erfindung geht aus von einer Kontaktfeder für ein bistabiles Relais zum Schatten hoher Ströme und ist zur Lösung der erwähnten Erfindungsaufgabe dadurch gekennzeichnet, daß die Kontaktfeder aus mehreren, übereinander gelegten Metallplättchen besteht, die an ihren Enden miteinander verbunden sind. Man - schafft somit den notwendigen hohen Querschnitt für die Leitung der hohen Ströme dadurch, daß eine entsprechende Anzahl der Metallplättchen übereinander gelegt wird, die vorzugweisegleich geschnitten, d.h. gleich profiliert sind. Trotzdem erreicht man die notwendige leichte Biegbarkeit der Kontaktfeder dadurch, daß diese übereinander gelegten Metallplättchen nicht einstückig ausgebildet sind, sondern daß diese nur an ihren Enden miteinander verbunden sind, so daß in der eigentlichen Biegezone die Metallplättchen voneinander frei sind. Geometrische Überlegungen belegen, daß man auch bei dieser Ausfuhrungsform eine ausreichende leichte Biegbarkeit erhält, weil die gewissermassen kombinierte Kontaktfeder eine Biegesteifigkeit hat, die nicht wesentlich höher ist als die Biegesteifigkeit eines einzelnen Metallplättchens. Dies beruht darauf, daß die Metallplättchen in ihrem mittleren Biegebereich frei gegeneinander verschoben werden können. Denkt man sich die Metallplättchen zu einem einzigen Block vereinigt, so gäbe es diese Verschiebbarkeit der Metallplättchen gegeneinander nicht mehr und dieser massive Block hätte daher eine so hohe Biegesteifigkeit daß er nicht mehr für den erfindungsgemäßen Zweck, nämlich fur ein bistabiles Relais, eingesetzt werden könnte.The other aspect of the invention is based on a contact spring for a bistable relay for shadowing high currents and is characterized in solving the above-mentioned object of the invention, characterized in that the contact spring consists of a plurality of metal plates, one on top of the other, which are connected to one another at their ends. One thus creates the necessary high cross-section for the conduction of the high currents by superimposing a corresponding number of metal plates which are preferably cut identically, i.e. are profiled the same. Nevertheless, the necessary easy bendability of the contact spring is achieved in that these superimposed metal plates are not formed in one piece, but rather are only connected to one another at their ends, so that the metal plates are free from one another in the actual bending zone. Geometrical considerations show that even with this embodiment, sufficient easy bendability is obtained because the contact spring, as it were combined, has a bending stiffness that is not significantly higher than the bending stiffness of a single metal plate. This is due to the fact that the metal plates can be freely shifted against each other in their central bending area. If one thinks of the metal plates combined into a single block, there would no longer be this displaceability of the metal plates against one another, and this massive block would therefore have such a high bending stiffness that it could no longer be used for the purpose according to the invention, namely for a bistable relay.

Die erwähnte erste Ausführungsform ist vorzugsweise dadurch gekennzeichnet, daß die Biegezone durch einen länglichen Streifen ausgebildet ist, wobei beidseitig des Streifens jeweils eine der Litzen angeordnet ist. Hier hat man also wenigstens zwei Litzen, die daher einen relativ hohen Strom aufnehmen können.The aforementioned first embodiment is preferably characterized in that the bending zone is formed by an elongated strip, one of the strands being arranged on both sides of the strip. So here you have at least two strands, which can therefore absorb a relatively high current.

Eine andere Ausführungsform ist dadurch gekennzeichnet, daß die Biegezone durch zwei voneinander beabstandete, parallele Streifen ausgebildet ist, zwischen denen sich wenigstens eine Litze erstreckt Diese Ausführungsform ist im Betrieb besonders symmetrisch und es können keine Verkantungen beim Verbiegen der Kontaktfeder auftreten.Another embodiment is characterized in that the bending zone is formed by two spaced-apart, parallel strips, between which at least one strand extends. This embodiment is particularly symmetrical in operation and no canting can occur when the contact spring is bent.

Im Betrieb muß die elektrisch leitende Verbindung zwischen den Enden der Litze und der eigentlichen Kontaktfeder hohen Wärmebelastungen widerstehen können. Eine übliche Lötverbindung ist hierfür nicht geeignet Daher ist die Erfindung weiterhin dadurch gekennzeichnet, daß die Litzen zwischen zwei Kontaktplatten eingeklemmt sind. Die Klemmkraft kann beispielsweise durch Punktschweissung aufgebracht werden, was wegen der hohen Stromübergangsflächen bevorzugt wird, oder auch durch Schrauben,Klemmen oder Nieten.In operation, the electrically conductive connection between the ends of the strand and the actual contact spring must be able to withstand high thermal loads. A conventional soldered connection is not suitable for this. Therefore, the invention is further characterized in that the strands are clamped between two contact plates. The clamping force can be applied, for example, by spot welding, which is preferred because of the high current transfer areas, or also by screws, clamping or riveting.

Die Erfindung wird im folgenden anhand von Ausführungsbeispielen näher erläutert, aus denen sich weitere wichtige Merkmale ergeben.The invention is explained in more detail below on the basis of exemplary embodiments, from which further important features result.

Between these two ends there is the bending zone of the contact spring, which is designated by position 6 shows that the clamping ends of the three springs 1 , 2 , 3 are combined in a block 7.

Die Figuren 2 und 3 zeigen nun Einzelheiten der Kontaktfeder 1. Bei dieser Ausführungsform hat sie ein H-förmiges Profil, wobei die Biegezone 6 durch einen länglichen Streifen 8 ausgebildet ist Der vordere Querstreifen 10 ist zu einem gabelförmigen Ende verlängert an dem die Kontaktstücke der Kontaktzone 5 ausgebildet sind.FIGS. 2 and 3 now show details of the contact spring 1 . In this embodiment, it has an H-shaped profile, the bending zone 6 being formed by an elongated strip 8. The front transverse strip 10 is extended to a fork-shaped end on which the contact pieces of the contact zone 5 are formed.

Erfindungsgemäß sind die mechanischen Eigenschaften, insbesondere die Biegungseigenschaften des Streifens 8 in der Biegezone 6, so ausgebildet daß die notwendige leichte Biegbarkeit für ein bistabiles Relais vorhanden ist Entsprechend hat der Streifen 8 einen geringen Querschnitt Um dennoch hohe Ströme in der Größenordnung von 25 Ampere aufnehmen zu können, sind zwei Litzen 11 elektrisch parallel zum Streifen 8 vorgesehen, deren Enden mit den Querstreifen 9,10 geeignet verbunden sind. Es handelt sich um verseilte oder verdrillte Litzen, deren Enden mit einer zusätzlichen Kontaktplatte 12 mit dem Material der eigentlichen Kontaktfeder 8,9,10 elektrisch gut leitend verbunden sind. Vorzugsweise ist hier eine Punktschweissung vorgesehen.According to the invention, the mechanical properties, in particular the bending properties of the strip 8 in the bending zone 6, are designed so that the necessary easy bendability for a bistable relay is present. Accordingly, the strip 8 has a small cross-section in order to nevertheless absorb high currents of the order of 25 amperes can are two strands 11 are provided electrically parallel to the strip 8, the ends of which are suitably connected to the transverse strips 9, 10. These are stranded or twisted strands, the ends of which are electrically conductively connected to the material of the actual contact spring 8, 9, 10 by an additional contact plate 12. Spot welding is preferably provided here.

Bei der Ausführungsform nach Figur 4 ist anstelle des H-Profils nach Figur 2 ein Kastenprofil mit zwei der Streifen 8 vorgesehen, die zueinander parallel und voneinander beabstandet an den Querstreifen 9,10 befestigt sind.In the embodiment according to FIG. 4, instead of the H-profile according to FIG. 2, a box profile with two of the strips 8 is provided, which are fastened to the transverse strips 9, 10 in parallel and at a distance from one another.

Hier ist wenigstens eine Litze 11 etwa mittig zwischen den Querstreifen 9,10 vorgesehen und daher den Längsstreifen 8 parallel geschaltet. Diese Ausführungsform zeichnet sich durch eine besonders gute Verwindungssteifigkeit und Verwindungsstabilität aus, weil der Kontakt besser geführt ist. Außerdem sind hier weniger Anschlußstellen, Position 12, vorgesehen, als bei den ersten Ausführungsbeispielen nach Figur 2.Here at least one strand 11 is provided approximately centrally between the transverse strips 9, 10 and therefore the longitudinal strips 8 are connected in parallel. This embodiment is characterized by a particularly good torsional rigidity and torsional stability because the contact is better managed. In addition, fewer connection points, position 12, are provided here than in the first exemplary embodiments according to FIG. 2.

Die dritte Ausführungsform nach Figur 5 macht von dem erwähnten zweiten Prinzip Gebrauch, wobei ohne die Litzen 11 mehrere, vorzugsweise gleichformatige, Metallplättchen 13 übereinander gelegt sind. Sie sind an ihren Enden miteinander zur Ausbildung eines Einspannendes 14 und eines Kontaktendes 15 verbunden, beispielsweise verschweisst.The third embodiment according to FIG. 5 makes use of the second principle mentioned, wherein without the strands 11, a plurality of metal plates 13, preferably of the same format, are placed one above the other.
