Definitions

  • the invention relates to a contact spring formed from a sheet metal strip, in which at one end of the strip a strip section is bent back in a U-shape opposite to the course of the strip and the strip has a cutout in the region of the bend for inserting a contact pin or contact knife.
  • Such a contact spring is known from US-E 29 513. It is clear that in this known contact spring to achieve a sufficient spring travel, the bent-back section must be dimensioned relatively long and that therefore a contact knife intended for contact with such a contact spring must also have a relatively large length in order to reach the distance from the free end of the contact spring to be able to penetrate the bent portion of the contact surface formed.
  • one of the two contact surfaces namely the contact surface, which is located on the side of the unbent part of the strip, is relatively rigid, so that the clamping effect, that is to say the contact force, has to be largely generated by the bent portion.
  • both contact surfaces are components of resilient webs, so that the contact surfaces can lie with an optimal spring action against a contact pin inserted between these surfaces or a contact knife inserted between these surfaces.
  • the contact spring is made from a spring sheet metal strip 1, which is formed at one end by a punching process and any subsequent bending to form a pin-shaped or knife-shaped connecting element 2.
  • the sheet metal strip 1 is divided at its other end into two webs 3, 4 which are arranged next to one another and parallel in the direction of the strip 1.
  • the longer of the two webs 3 has at its free end 5 an arm 6 provided transversely to the direction of the strip 1.
  • This, at its free end 7 widened arm 6 is dimensioned such that it is arranged with its widening 8 in the unbent state of the strip 1 separated by an air gap 9 from the web 4 in extension of the shorter web 4.
  • the shorter web 4 is provided with a curvature at its free end and forms a contact surface 10 of the contact spring in the region of this curvature.
  • the widening 8 of the arm 6 forms a further contact surface 11 with the surface that lies opposite the contact surface 10 of the shorter web 4.
  • the air gap 9 lying in the unbent state of the longer web 3 between the contact surfaces 10 and 11 forms an insertion opening in the bent state of the web 3, through which a contact pin or a contact knife can be inserted between the contact surfaces 10 and 11. From the figures it can be seen that both contact surfaces 10, 11 of the bend 18 of the longer web 3 are provided immediately adjacent to one end of the contact spring, so that a contact pin or a contact knife does not require a great length to pass between the contact surfaces 10, 11 reach.

Description

Die Erfindung bezieht sich auf eine aus einem Blechstreifen gebildete Kontaktfeder, bei der an einem Ende des Streifens ein Streifenabschnitt entgegengesetzt zum Verlauf des Streifens U-förmig zurückgebogen ist und der Streifen im Bereich der Biegung eine Aussparung zum Durchstecken eines Kontaktstiftes oder Kontaktmessers aufweist.The invention relates to a contact spring formed from a sheet metal strip, in which at one end of the strip a strip section is bent back in a U-shape opposite to the course of the strip and the strip has a cutout in the region of the bend for inserting a contact pin or contact knife.

Eine derartige Kontaktfeder ist aus der US-E 29 513 bekannt. Es ist klar, daß bei dieser bekannten Kontaktfeder zur Erzielung eines ausreichenden Federweges der zurückgebogene Abschnitt relativ lang bemessen werden muß und daß deshalb auch ein zur Kontaktgabe mit einer solchen Kontaktfeder bestimmtes Kontaktmesser eine relativ große Länge besitzen muß, um bis zu der vom freien Ende des zurückgebogenen Abschnittes gebildeten Kontaktfläche vordringen zu können. Außerdem ist eine der beiden Kontaktflächen, nämlich die Kontaktfläche, die sich auf der Seite des unabgebogenen Teils des Streifens befindet, relativ starr, so daß die Klemmwirkung, also die Kontaktkraft, weitgehend von dem abgebogenen Abschnitt erzeugt werden muß. Es kommt schließlich noch hinzu, daß neuerdings bei Kontaktfedern nur noch die eigentlichen Kontaktflächen, also die mit einem Gegenkontaktorgan (z.B. Kontaktmesser oder Kontaktstift) in Berührung tretenden Bereiche mit einer Edelmetallschicht versehen werden, um Kosten einzusparen. Bei der bekannten Kontaktfeder liegen im unabgebogenen Zustand des endseitigen Streifenabschnittes die Kontaktflächen relativ weit auseinander, so daß zwei örtlich voneinander getrennte Edelmetallschichtbereiche bei jeder Kontaktfeder erforderlich sind.Such a contact spring is known from US-E 29 513. It is clear that in this known contact spring to achieve a sufficient spring travel, the bent-back section must be dimensioned relatively long and that therefore a contact knife intended for contact with such a contact spring must also have a relatively large length in order to reach the distance from the free end of the contact spring to be able to penetrate the bent portion of the contact surface formed. In addition, one of the two contact surfaces, namely the contact surface, which is located on the side of the unbent part of the strip, is relatively rigid, so that the clamping effect, that is to say the contact force, has to be largely generated by the bent portion. Finally, there is also the fact that, in the case of contact springs, only the actual contact surfaces, i.e. the areas that come into contact with a counter-contact element (e.g. contact knife or contact pin), are now provided with a noble metal layer in order to save costs. In the known contact spring, in the unbent state of the end strip section, the contact surfaces are relatively far apart, so that two locally separated precious metal layer regions are required for each contact spring.

Darüber hinaus ist es der älteren Patentanmeldung EP-A 0 197 047, die als Stand der Technik nach Artikel 54(3) EPÜ gilt, entnehmbar, bei einer solchen Kontaktfeder die Kontaktflächen in nächster Nähe der U-förmigen Biegung des Kontaktstreifens vorzusehen und diejenige Kontaktfläche, die sich auf der Seite des zurückgebogenen Streifenabschnittes befindet, durch zumindest teilweisen Freischnitt zur U-förmigen Biegung des Streifens hin elastisch nachgiebig zu gestalten.In addition, it is apparent from the earlier patent application EP-A 0 197 047, which is considered the state of the art under Article 54 (3) EPC, to provide the contact surfaces in the vicinity of the U-shaped bend of the contact strip and the contact surface in such a contact spring , which is located on the side of the bent-back strip section, to be made elastically flexible by at least partially free cutting to the U-shaped bend of the strip.

Demgegenüber ist es Aufgabe vorliegender Erfindung, eine Kontaktfeder der eingangs genannten Art so auszubilden, daß beide Kontaktflächen der Kontaktfeder, zwischen die ein Kontaktmesser oder ein Kontaktstift eingesteckt werden kann, federnd nachgiebig sind.In contrast, it is an object of the present invention to design a contact spring of the type mentioned in such a way that both contact surfaces of the contact spring, between which a contact knife or a contact pin can be inserted, are resilient.

Erfindungsgemäß ergibt sich die Lösung dieser Aufgabe durch eine den kennzeichnenden Merkmalen des Patentanspruches 1 entsprechende Ausbildung der Kontaktfeder.According to the invention this object is achieved by a design of the contact spring corresponding to the characterizing features of claim 1.

Auf diese Weise sind beide Kontaktflächen Bestandteile von federnd nachgiebigen Stegen, so daß sich die Kontaktflächen mit einer optimalen Federwirkung gegen einen zwischen diese Fiächen eingeschobenen Kontaktstift bzw. ein zwischen diese Flächen eingeschobenes Kontaktmesser legen können.In this way, both contact surfaces are components of resilient webs, so that the contact surfaces can lie with an optimal spring action against a contact pin inserted between these surfaces or a contact knife inserted between these surfaces.

Eine weitere Ausgestaltung der Erfindung ergibt sich aus den Merkmalen des Unteranspruches.A further embodiment of the invention results from the features of the subclaim.

Ausführungsbeispiele der Kontaktfeder nach der Erfindung werden nachfolgend anhand von vier Figuren noch näher erläutert.Embodiments of the contact spring according to the invention are explained in more detail below with reference to four figures.

Dabei zeigen jeweils in Schrägsicht und vergrößert,

  • Fig. 1 und Fig. 2 eine erste Ausführungsform der Kontaktfeder im unabgebogenen Zustand (Fig. 1) und im fertigen Zustand (Fig. 2) und
  • Fig.3 und Fig. 4 eine zweite Ausführungsform der Kontaktfeder, wobei insbesondere Fig. 3 zeigt, daß die zur Herstellung der Kontaktfeder verwendeten Federblechstreifen vorteilhaft Querstege eines Federblechbandes sein können.
Each shows in an oblique view and enlarged,
  • Fig. 1 and Fig. 2 shows a first embodiment of the contact spring in the unbent state (Fig. 1) and in the finished state (Fig. 2) and
  • Fig. 3 and Fig. 4 shows a second embodiment of the contact spring, in particular Fig. 3 shows that the spring sheet metal strips used to produce the contact spring can advantageously be transverse webs of a spring sheet metal strip.

Im einzelnen ist den Figuren zu entnehmen, daß die Kontaktfeder aus einem Federblechstreifen 1 hergestellt ist, der an einem Ende durch einen Stanzvorgang und eventueller nachfolgender Biegung zu einem stift- oder messerförmigen Anschlußorgan 2 geformt ist.In detail, it can be seen from the figures that the contact spring is made from a spring sheet metal strip 1, which is formed at one end by a punching process and any subsequent bending to form a pin-shaped or knife-shaped connecting element 2.

Bei dem Ausführungsbeispiel nach Fig. 1 und Fig. 2 ist der Blechstreifen 1 an seinem anderen Ende in zwei in Verlaufsrichtung des Streifens 1 parallele nebeneinander angeordnete Stege 3, 4 aufgeteilt. Der längere der beiden Stege 3 weist an seinem freien Ende 5 einen quer zur Verlaufsrichtung des Streifens 1 vorgesehenen Arm 6 auf. Dieser, an seinem freien Ende 7 verbreiterte Arm 6 ist so bemessen, daß er mit seiner Verbreiterung 8 im unabgebogenen Zustand des Streifens 1 durch einen Luftspalt 9 vom Steg 4 getrennt in Verlängerung des kürzeren Steges 4 angeordnet ist.In the exemplary embodiment according to FIGS. 1 and 2, the sheet metal strip 1 is divided at its other end into two webs 3, 4 which are arranged next to one another and parallel in the direction of the strip 1. The longer of the two webs 3 has at its free end 5 an arm 6 provided transversely to the direction of the strip 1. This, at its free end 7 widened arm 6 is dimensioned such that it is arranged with its widening 8 in the unbent state of the strip 1 separated by an air gap 9 from the web 4 in extension of the shorter web 4.

Der kürzere Steg 4 ist an seinem freien Ende mit einer Wölbung versehen und bildet im Bereich dieser Wölbung eine Kontaktfläche 10 der Kontaktfeder.The shorter web 4 is provided with a curvature at its free end and forms a contact surface 10 of the contact spring in the region of this curvature.

Durch eine U-förmige Biegung des längeren Steges 3 ist, wie Fig. 2 zeigt, der Arm 6 mit seiner Verbreiterung 8 der Kontaktfläche 10 des kürzeren Steges 4 gegenübergestellt. Die Verbreiterung 8 des Armes 6 bildet mit der Fläche, die der Kontaktfläche 10 des kürzeren Steges 4 gegenüberliegt, eine weitere Kontaktfläche 11.A U-shaped bend of the longer web 3, as shown in FIG. 2, contrasts the arm 6 with its widening 8 to the contact surface 10 of the shorter web 4. The widening 8 of the arm 6 forms a further contact surface 11 with the surface that lies opposite the contact surface 10 of the shorter web 4.

Der im unabgebogenen Zustand des längeren Steges 3 zwischen den Kontaktflächen 10 und 11 liegende Luftspalt 9 bildet im abgebogenen Zustand des Steges 3 eine Einstecköffnung, durch die ein Kontaktstift oder ein Kontaktmesser zwischen die Kontaktflächen 10 und 11 eingesteckt werden kann. Aus den Figuren ist ersichtlich, daß beide Kontaktflächen 10, 11 der Biegung 18 des längeren Steges 3 unmittelbar benachbart an dem einen Ende der Kontaktfeder vorgesehen sind, so daß ein Kontaktstift oder ein Kontaktmesser keine große Länge benötigt, um zwischen die Kontaktflächen 10, 11 zu gelangen.The air gap 9 lying in the unbent state of the longer web 3 between the contact surfaces 10 and 11 forms an insertion opening in the bent state of the web 3, through which a contact pin or a contact knife can be inserted between the contact surfaces 10 and 11. From the figures it can be seen that both contact surfaces 10, 11 of the bend 18 of the longer web 3 are provided immediately adjacent to one end of the contact spring, so that a contact pin or a contact knife does not require a great length to pass between the contact surfaces 10, 11 reach.

Im Ausführungsbeispiel nach Fig. 3 und nach Fig. 4 ist der Streifen 1 an dem Ende des Streifens, der vom Anschlußorgan 2 abgewandt ist, in drei zueinander parallele Stege 12, 13, 14 aufgeteilt. Die beiden äußeren Stege 12,14 sind an ihrem freien Ende durch den Arm 6 miteinander verbunden, und der Arm 6 weist in seiner Mitte die Verbreiterung 8 auf, die sich dadurch in Verlängerung des kürzeren Steges 13 befindet, der durch einen Luftspalt 9 von der Verbreiterung 8 in Verlaufsrichtung des Streifens 1 getrennt ist, wenn sich die beiden äußeren Stege 12, 14 im unabgebogenen Zustand befinden.In the exemplary embodiment according to FIG. 3 and according to FIG. 4, the strip 1 is divided into three mutually parallel webs 12, 13, 14 at the end of the strip which faces away from the connecting element 2. The two outer webs 12, 14 are connected to one another at their free end by the arm 6, and the arm 6 has the widening 8 in its center, which is thereby an extension of the shorter web 13, which is separated by an air gap 9 from the Widening 8 in the direction of the strip 1 is separated when the two outer webs 12, 14 are in the unbent state.

Durch eine U-förmige Rückbiegung 18 der äußeren Stege 12, 14 wird die Verbreiterung 8 des Armes 6 dem freien Ende des kürzeren Steges 13 gegenübergestellt. Die dabei einander gegenüberstehenden Flächen der Verbreiterung 8 des Armes 6 und des freien Endes des Steges 13 sind als Kontaktflächen 10, 11 ausgebildet, zwischen die ein Kontaktstift oder ein Kontaktmesser eingesteckt werden kann, der bzw. das durch ein Fenster 16 hindurchgeführt wird, das durch die gebogenen Bereiche 17 der längeren Stege 12, 14 begrenzt ist.The widening 8 of the arm 6 is compared to the free end of the shorter web 13 by a U-shaped back bend 18 of the outer webs 12, 14. The mutually opposing surfaces of the widening 8 of the arm 6 and the free end of the web 13 are designed as contact surfaces 10, 11, between which a contact pin or a contact knife can be inserted, which or is passed through a window 16, which through the curved areas 17 of the longer webs 12, 14 is limited.

Aus Fig. 3 ist ersichtlich, daß die einzelnen Blechstreifen 1 als Sprossen eines leiterförmigen Blechbandes aus dem Blechband herausgearbeitet sein können, wobei sich die Kontaktflächen 10, 11 durch die spezielle Konstruktion der Kontaktfeder auf derselben Seite des Blechbandes befinden und sich außerdem auf jedem Streifen auf einen schmalen Bereich 19 konzentrieren, was die Beschichtung der Bereiche der Streifen 1, die zur Bildung der Kontaktflächen 10, 11 vorgesehen sind, mit Edelmetall wesentlich begünstigt.From Fig. 3 it can be seen that the individual sheet metal strips 1 can be worked out as rungs of a ladder-shaped sheet metal strip from the sheet metal strip, the contact surfaces 10, 11 being located on the same side of the sheet metal strip due to the special design of the contact spring and also on each strip concentrate a narrow area 19, which favors the coating of the areas of the strips 1, which are provided for forming the contact surfaces 10, 11, with precious metal.
