Description

Die Erfindung betrifft eine Kontaktfeder-Anordnung, bestehend aus zwei gegenüberliegend angeordneten Kontaktfedern die je einen Kontaktkopf aufweisen, der eine Kontaktfläche und zwei Seitenflächen sowie eine der Kontaktfläche gegenüberliegende Fläche aufweist, wobei die beiden Kontaktflächen einander gegenüberliegen.The invention relates to a contact spring arrangement, consisting of two oppositely arranged Contact springs each have a contact head, the one Contact surface and two side surfaces as well as one of the Has contact surface opposite surface, the the two contact surfaces face each other.

Eine einfache Art der Herstellung derartiger KontaktfederAnordnungen besteht darin, sie aus flachem Blech auszustanzen. Daraus folgt aber, daß die Kontaktfläche diejenige Fläche ist, entlang der der Stanzschnitt erfolgt ist. Diese Kontaktfläche weist daher Schneidriefen auf (vgl. die Schneidriefen 16 in Figur 3). Wird nun zwischen zwei derartige Kontaktfedern ein Steckelement eingesteckt und dadurch ein elektrischer Kontakt hergestellt, so wirken die Schneidriefen auf die Dauer wie eine Feile. Die Stecker werden also sehr schnell abgenützt. Außerdem ist der entstehende elektrische Kontakt nicht gut. Ferner ist die Breite des Kontaktes durch die Dicke des Materials, aus dem die Kontaktfeder-Anordnung ausgestanzt wird, beschränkt. A simple way of producing such contact spring arrangements consists of them made of flat sheet metal to punch out. However, it follows that the contact surface is the area along which the die cut is made is. This contact surface therefore has cutting grooves (cf. the cutting grooves 16 in Figure 3). Will now be between two such contact springs inserted a plug element and thereby making an electrical contact, they act Cutting marks in the long run like a file. The plugs are worn out very quickly. In addition, the resulting electrical contact is not good. Furthermore, the Width of contact by the thickness of the material from which the contact spring arrangement is punched out, limited.

Die US-PS 4,660,922 zeigt einen Preßfit-Stift, bei dem der Kontaktbereich zylindrisch ist. Der Kontaktkopf (head) dient dazu, den Stift, der Teil einer Steckerleiste ist, fest in einem Aufnahmeteil 46 (Figur 5A) zu verankern. Zwar hat dieses Bauteil eine konvexe Fläche und Seitenflächen. Das Problem, die bei einem Stanzschnitt entstehenden Riefen einer Kontaktfläche zu beseitigen, ist dabei aber nicht gelöst.The US-PS 4,660,922 shows a press fit pin in which the Contact area is cylindrical. The contact head (head) serves to do this, the pin, which is part of a power strip, firmly in anchoring part 46 (Figure 5A). Has this component has a convex surface and side surfaces. The Problem with the scoring caused by a die cut eliminating a contact surface is not solved.

Das DE-GM 66 09 552 zeigt durch Stanzen hergestellte Ausnehmungen. Sie dienen jedoch nicht zur Verbesserung der Kontaktfläche, sondern zur Verankerung des Stiftes in einer Halterungsscheibe (siehe S. 5, Z. 10).The DE-GM 66 09 552 shows manufactured by stamping Recesses. However, they are not used to improve Contact surface, but for anchoring the pin in a Bracket washer (see p. 5, line 10).

Aufgabe der Erfindung ist es, eine Kontaktfeder-Anordnung der eingangs genannten Art sowie ein Verfahren zu ihrer Herstellung zu schaffen, wobei die Kontaktfläche verbessert werden soll.The object of the invention is a contact spring arrangement of the type mentioned above and a process for their To create manufacturing, the contact area improved shall be.

Die Aufgabe wird bei einer Kontaktfederanordnung der genannten Art erfindungsgemäß durch die Merkmale des Anspruchs 1 und durch ein Verfahren mit den Merkmalen des Anspruchs 6 gelöst. The task is in a contact spring arrangement mentioned type according to the invention by the features of Claim 1 and by a method with the features of Claim 6 solved.

Durch die Einprägung der Ausnehmung fließt - bei entsprechender Ausbildung der Prägeform - das Material der Kontaktflächen in die Breite. Dadurch wird die Kontaktfläche verbreitert und die Riefen, die noch von dem vorherigen Stanzvorgang herrühren, werden geglättet. Es kann sich dabei eine quer zur Längsrichtung der Kontaktfeder konvexe Fläche ausbilden, so daß die Kontaktfläche insgesamt die Form eines Löffels annimmt. Auf diese Weise wird mit einfachen Mitteln die Kontaktfläche vergrößert und qualitativ verbessert.By embossing the recess - flows appropriate design of the embossing mold - the material of the Contact areas in width. This will make the contact area widened and the scoring still from the previous one The punching process are smoothed. It can happen a surface which is convex transversely to the longitudinal direction of the contact spring form, so that the contact surface as a whole Spoon accepts. This way, with simple means the contact area enlarged and improved in quality.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen definiert, ebenso das Verfahren zur Herstellung derartiger Kontaktfedern.Advantageous developments of the invention are in the Defined subclaims, as well as the method for Manufacture of such contact springs.

Figur 1 zeigt eine Kontaktfederanordnung 20 mit zwei Kontaktfedern 21 und 22. Diese Kontaktfederanordnung ist in eine Bohrung 23 einer Kunststoffplatte 24 (Leiterplatte) eingesetzt und an ihrem über die Kunststoffplatte 24 hervorstehenden Ende mit einem Kontaktstift 25 versehen. Bei diesem kann es sich um einen sog. Pressfit-Kontakt handeln, d.h. um einen Kontakt, der einen (nicht gezeigten) elastisch zusammenpressbaren Bereich aufweist, mit dem er in der Bohrung einer weiteren Kunststoffplatte (Leiterplatte) gehalten wird. Figure 1 shows a contact spring assembly 20 with two Contact springs 21 and 22. This contact spring arrangement is in a bore 23 of a plastic plate 24 (printed circuit board) used and on her over the plastic plate 24th projecting end provided with a contact pin 25. At this can be a so-called press-fit contact, i.e. a contact that is elastic (not shown) Compressible area with which he in the Drilling another plastic plate (printed circuit board) is held.

Mehrere derartige Kontaktfederanordnungen sind in mehreren Bohrungen 23, z.B. eines Feldes von 3 mal 32 Bohrungen eines Steckerfeldes angeordnet.Several such contact spring arrangements are in several Holes 23, e.g. a field of 3 times 32 holes one Plug field arranged.

Die Kontaktfedern 21, 22 weisen jeweils Kontaktköpfe 2, 2' auf. Zur Herstellung eines Kontaktes wird nun ein Stift (nicht gezeigt) von oben (in Figur 1) zwischen die zwei Kontaktköpfe 2, 2' eingeschoben, und zwar durch die Einschiebeöffnung 26.The contact springs 21, 22 each have contact heads 2, 2 ' on. A pin is now used to make a contact (not shown) from above (in Figure 1) between the two Contact heads 2, 2 'inserted through the Insertion opening 26.

Figur 3 zeigt den aus Blech ausgestanzten Rohling 10 einer Kontaktfeder mit Seitenflächen 15 und einer Kontaktfläche 14. Die Breite b0 eines Kontaktkopfes 2 ist dabei gleich der Dicke des Blechs, aus dem die Kontaktfedern 21, 22 ausgestanzt werden. Der ausgestanzte Rohling weist, wie aus Figur 3 ersichtlich, Schneidriefen 16 auf, die vom Stanzvorgang, der in Richtung S stattfindet, herrühren. So sehen die Kontaktfedern nach dem hier in Frage kommenden Stand der Technik aus. Wird nun zwischen zwei mit ihren Kontaktflächen 14 gegenüberliegende Kontaktfedern 21, 22 ein (nicht gezeigtes) Steckelement gesteckt, so ist ersichtlich, daß die Riefen 16 praktisch wie eine Feile an der Kontaktfläche des Steckelementes wirken. Außerdem ergibt die mit den Schneideriefen 16 versehene und durch den Schnittvorgang entstandene Kontaktfläche 14 keinen guten elektrischen Kontakt. Ferner ist die Breite b0 der Kontaktfläche auf die Dicke des Blechs, aus dem die Kontaktfeder ausgestanzt wurde, begrenzt.FIG. 3 shows the blank 10 punched out of sheet metal of a contact spring with side faces 15 and a contact face 14. The width b 0 of a contact head 2 is equal to the thickness of the sheet from which the contact springs 21, 22 are punched out. The punched blank, as can be seen in FIG. 3, has cutting grooves 16 which result from the punching process which takes place in the S direction. This is how the contact springs look according to the state of the art in question here. If a plug element (not shown) is inserted between two contact springs 21, 22 with their contact surfaces 14, it can be seen that the grooves 16 act practically like a file on the contact surface of the plug element. In addition, the contact surface 14 provided with the cutting grooves 16 and created by the cutting process does not provide good electrical contact. Furthermore, the width b 0 of the contact surface is limited to the thickness of the sheet from which the contact spring was punched out.

Nach dem ersten Ausführungsbeispiel der Erfindung wird nun eine derartige Kontaktfeder dadurch weiter bearbeitet, daß, wie aus Figur 5 ersichtlich, in die beiden Seitenflächen 15 Ausnehmungen 7 in Prägerichtung P eingeprägt werden. Das durch diesen Einprägevorgang verdrängte Material bringt die Kontaktfläche 14 zum Fließen. Damit wird einerseits die Kontaktfeder in der Prägeform geglättet, so daß die Schneidriefen 16, die vom vorhergehenden Stanzvorgang her rühren, weitgehend verschwinden. Es entsteht die Kontaktfläche 4 des fertig bearbeiteten Kontaktkopfes 2 bzw. 2'. Andererseits fließt die Kontaktfläche auch in die Breite, selbstverständlich nur unter der Voraussetzung, daß die Prägeform entsprechend gestaltet ist. Die Kontaktfläche 4 hat dann eine Breite b1, die größer als die ursprüngliche Breite b0 des nicht mit den eingeprägten Ausnehmungen 7 versehenen Rohlings 10 ist. Gleichzeitig entsteht damit, ebenfalls wieder unter der Voraussetzung, daß die Prägeform entsprechend gestaltet ist, auch eine konvexe Form quer zur Längsrichtung A der Kontaktfeder (vgl. Figur 7). Dadurch entsteht die löffelförmige Kontaktfläche 4, geglättet durch den Prägevorgang, die auch einen guten elektrischen Kontakt herstellt. According to the first embodiment of the invention, such a contact spring is processed further in that, as can be seen in FIG. 5, 15 recesses 7 are embossed in the embossing direction P in the two side surfaces. The material displaced by this embossing process causes the contact surface 14 to flow. On the one hand, the contact spring is smoothed in the embossing mold, so that the cutting grooves 16, which result from the previous punching process, largely disappear. The contact surface 4 of the finished contact head 2 or 2 'is created. On the other hand, the contact surface also flows in width, of course only on the condition that the embossing shape is designed accordingly. The contact surface 4 then has a width b 1 which is greater than the original width b 0 of the blank 10 not provided with the embossed recesses 7. At the same time, this also results in a convex shape transversely to the longitudinal direction A of the contact spring, again provided that the embossing shape is designed accordingly (see FIG. 7). This creates the spoon-shaped contact surface 4, smoothed by the embossing process, which also makes good electrical contact.

Im Extremfall können die Ausnehmungen 7 soweit eingeprägt sein, daß sie ineinander übergehen, d.h. so daß, wie durch die gestrichelten Linien in Figur 7 angedeutet, eine durchgehende Ausnehmung 7' entsteht.In extreme cases, the recesses 7 can be stamped so far be that they merge, i.e. so how through the dashed lines indicated in Figure 7, a continuous recess 7 'arises.

Beim zweiten Ausführungsbeispiel nach Figur 8 sind Ausnehmungen 17 so eingeprägt und ausgebildet, daß sie zur Fläche 6, die der Kontakfläche 4 gegenüberliegt, offen sind.In the second embodiment of Figure 8 are Recesses 17 are stamped and formed so that they are Surface 6, which is opposite the contact surface 4, are open.

Beim dritten Ausführungsbeispiel nach Figur 9 ist nur eine Tasche 18 eingeprägt, und zwar in die Fläche 6. In the third exemplary embodiment according to FIG. 9 there is only one Pocket 18 embossed, namely in the surface 6.
