Gattungsgemäße Kontakte werden häufig in großer Zahl nebeneinander in Kontaktträger eines Steckverbinders eingesetzt, um einen Steckverbinder mit hoher Kontaktdichte herzustellen. Solche Steckverbinder haben den großen Vorteil, dass mit einem Steckvorgang eine Vielzahl von am Steckverbinder angeordneten Zuleitungen mit Gegenkontakten beispielsweise einer Platine oder einem sonstigen elektronischen Bauteil verbunden werden können.Generic contacts are often used in large numbers next to each other in the contact carrier of a connector in order to produce a connector with a high contact density. Such connectors have the great advantage that a multiplicity of supply lines arranged on the connector can be connected to counter-contacts, for example on a circuit board or some other electronic component, in a single insertion process.

Einen solchen Kontakt zeigt beispielsweise DE 43 30 390 A1 .Such a contact shows, for example DE 43 30 390 A1 .

Steckverbinder stehen mit fortschreitender Entwicklung im Spannungsfeld von Miniaturisierungsanforderungen, elektrischer Sicherheit und der Übertragungsnotwendigkeit hoher Ströme. Die Verkleinerung der Steckverbinder hat eine Verringerung der Abstände zwischen den einzelnen Kontakten zur Folge, womit die Isolationsabstände sinken. Die Kontakte selber werden schmaler. Hierdurch sinken die Leiterquerschnitte was der Übertragung hoher Ströme Grenzen setzt. Gleichzeitig stehen der Verkleinerung von Kontakten die Anforderungen an eine sichere Übertragung von elektrischen Strömen und Spannung auf die Gegenkontakte gegenüber. Die Kontaktierung mit Gegenkontakten bedarf gewisser Andruckkräfte, die unter anderem von der Steifigkeit des Kontaktmaterials und somit von dessen Materialstärke abhängig sind. Insbesondere bei Steckverbindern gemäß RAST-Standard bestehen seit längerem Tendenzen, vermehrt Steckverbindergrößen durch den nächstkleineren Steckverbinder gemäß diesem Standard zu substituieren, ohne dabei die Anforderungen an Kontaktsicherheit und Übertragungskapazität zu verringern.With progressive development, connectors are caught between miniaturization requirements, electrical safety and Transmission requirement of high currents. The miniaturization of the connectors results in a reduction in the distances between the individual contacts, which means that the insulation distances decrease. The contacts themselves become narrower. This reduces the conductor cross-sections, which limits the transmission of high currents. At the same time, the miniaturization of contacts is opposed to the requirements for safe transmission of electrical currents and voltage to the mating contacts. Contacting with mating contacts requires certain pressure forces, which depend, among other things, on the rigidity of the contact material and thus on its material thickness. In the case of connectors in particular in accordance with the RAST standard, there have long been tendencies towards increasingly substituting connector sizes with the next smaller connector in accordance with this standard, without reducing the requirements for contact reliability and transmission capacity.

Aufgabe der Erfindung ist es, einen Steckverbinder zu schaffen, welcher die Voraussetzung für eine Verkleinerung von Steckverbindern bietet.The object of the invention is to create a connector which offers the prerequisite for miniaturizing connectors.

Gelöst wird die Erfindung von einem Steckverbinder mit den Merkmalen des Anspruchs 1, insbesondere mit dessen kennzeichnenden Merkmalen, wonach der Einspannabschnitt im Ursprungsbereich des jeweiligen Kontaktarmes einen Freischnitt aufweist, so dass der Anschlag in Richtung der Kontaktkuppen in den Aufnahmeraum hineinragt.The invention is solved by a connector with the features of claim 1, in particular with its characterizing features, according to which the clamping section has a free cut in the origin area of the respective contact arm, so that the stop protrudes in the direction of the contact tips into the receiving space.

Mit den kennzeichnenden Merkmalen ist es möglich, die Gesamtlänge des Kontaktes zu reduzieren, die effektive Länge des Kontaktarms jedoch beizubehalten. Da der Einspannabschnitt, mit welchem der Kontakt im Kontaktträger gehalten ist, eine gewisse Mindestgröße erfordert, insbesondere auch um die vergleichsweise langen Kontaktarme gegen Querkräfte zu stabilisieren, ist die Reduktion der in Steckrichtung gemessenen Länge des Einspannabschnitts nicht ohne weiteres möglich.With the characteristic features it is possible to reduce the overall length of the contact while maintaining the effective length of the contact arm. Since the clamping section, with which the contact is held in the contact carrier, requires a certain minimum size, in particular to stabilize the comparatively long contact arms against lateral forces, reducing the length of the clamping section measured in the insertion direction is not easily possible.

Durch den Freischnitt im Bereich des Ursprungs des jeweiligen Kontaktarms wird die Lage des Kontaktarmursprungs im Einspannabschnitt gegenüber dem Anschlag des Einspannabschnitts zurückgesetzt. Hierdurch kann die effektive Kontaktarmlänge konstant gehalten werden. Gleichzeitig ist es möglich, die Kontaktkuppen bezogen auf den Anschlag des Einspannabschnitts in Einsteckrichtung zurückzuversetzen. Bei ansonsten unveränderter Kontaktarmgeometrie bleiben somit trotz kürzerer Kontaktlänge die Federeigenschaften der Kontaktarme des Kontaktes erhalten.Due to the cutout in the area of the origin of the respective contact arm, the position of the contact arm origin in the clamping section is set back relative to the stop of the clamping section. As a result, the effective contact arm length can be kept constant. At the same time, it is possible to move the contact tips back in the insertion direction relative to the stop of the clamping section. With otherwise unchanged contact arm geometry, the spring properties of the contact arms of the contact are retained despite the shorter contact length.

In entsprechender Anwendung der Erfindung ist es jedoch auch möglich, bei konstant gehaltener Kontaktlänge den effektiven Kontaktarm zu verlängern, in dem lediglich freigeschnitten wird, der Kontaktarm jedoch nicht entsprechend zurückgenommen ist.With a corresponding application of the invention, however, it is also possible to lengthen the effective contact arm while the contact length is kept constant by merely cutting free, but not correspondingly withdrawing the contact arm.

Die Elastizität des Kontaktarms lässt sich besonders gut beeinflussen, insbesondere steigern, wenn jeder Kontaktarm in seinem Ursprungsbereich einen die entlang der Walzseite und orthogonal zur Trennlinie gemessene Kontaktarmbreite verringernden Ausschnitt aufweist, wobei es fertigungstechnisch von erheblichem Vorteil ist, wenn der Freischnitt des Einspannabschnitts in den Ausschnitt des jeweiligen Kontaktarmes übergeht und insbesondere beide Abschnitte derselben Kreislinie sind.The elasticity of the contact arm can be influenced particularly well, in particular increased if each contact arm has a cut-out in its original area that reduces the contact arm width measured along the rolling side and orthogonally to the parting line, it being of considerable advantage in terms of production technology if the cut-out of the clamping section is in the cut-out of the respective contact arm and, in particular, both are sections of the same circular line.

Durch die Reduktion der Kontaktarmbreite entsteht eine höhere Elastizität des Kontaktarms in seinem Ursprungsbereich, wenn darüber hinaus - wie ausgeführt - der Freischnitt des Einspannabschnitts in den Ausschnitt des jeweiligen Kontaktarms übergeht, beispielsweise beide Abschnitte Teile derselben Kreislinie oder ähnlichen Geometrieverläufen sind, hat dies für den Stanzvorgang zur Herstellung des erfindungsgemäßen Kontaktes erhebliche Vorteile, weil hier mit einem einzigen Werkzeug zu arbeiten ist.The reduction in the width of the contact arm results in greater elasticity of the contact arm in its original area, if - as explained - the cut-out of the clamping section merges into the cut-out of the respective contact arm, for example both sections are parts of the same circular line or similar geometry, this has an impact on the stamping process for the production of the contact according to the invention significant advantages, because here is to work with a single tool.

Vorgesehen ist ferner, dass die Kontaktarme den Aufnahmeraum in Richtung der Kontaktkuppen verengen.It is also provided that the contact arms narrow the receiving space in the direction of the contact tips.

Die Kontaktarme laufen folglich - ausgehend von ihrem Ursprung - schräg aufeinander zu, bis sie die erforderliche Breite eines Steckschlitzes durch den Abstand der Kontaktkuppen definieren. Der Kontakt ist folglich im Ursprung der Kontaktarme am Einspannabschnitt vergleichsweise breit und im Bereich der Kontaktkuppen demgegenüber schmaler. Gegenüber Kontaktarmen, die in Einsteckrichtung geradlinig verlaufen, hat diese Gestaltung den wesentlichen Vorteil, dass Kontaktarme einer definierten Länge in Einsteckrichtung weniger Bauraum einnehmen. Auch hierdurch lässt sich wiederum insbesondere eine Verkürzung der Kontakte und somit des Steckverbinders durchführen oder es lassen sich bei gleicher Kontaktlänge längere Kontaktarme realisieren.The contact arms consequently run - starting from their origin - at an angle towards one another until they define the required width of a plug-in slot by the distance between the contact tips. The contact is consequently comparatively wide at the origin of the contact arms at the clamping section and, in contrast, narrower in the area of the contact tips. Compared to contact arms that run in a straight line in the direction of insertion, this design has the significant advantage that contact arms of a defined length take up less space in the direction of insertion. In this way, too, the contacts and thus the plug connector can in turn be shortened, or longer contact arms can be realized with the same contact length.

Eine weitere Möglichkeit, die Elastizität der Kontaktarme zu beeinflussen und insbesondere bereichsweise zu verringern oder zu erhöhen, besteht dadurch, dass jeder Kontaktarm zwischen seinem Ursprung und seiner Kontaktkuppe eine äußere Stanzkante mit einer äußeren Stufenkontur und eine innere Stanzkante mit einer inneren Stufenkontur aufweist, insbesondere wenn die innere Stufenkontur und die äußere Stufenkontur eines jeden Kontaktarmes asymmetrisch zueinander verlaufen und hierdurch schmale und breite Kontaktarmabschnitte entstehen.Another way of influencing the elasticity of the contact arms and reducing or increasing it in certain areas is that each contact arm has an outer punched edge with an outer step contour and an inner punched edge with an inner step contour between its origin and its contact tip, especially if the inner step contour and the outer step contour of each contact arm run asymmetrically to one another and this results in narrow and wide contact arm sections.

Besonders bevorzugt ist es, wenn die Kontaktarme und/oder der Einspannabschnitt spiegelsymmetrisch zur Trennlinie ausgebildet ist.It is particularly preferred if the contact arms and/or the clamping section are mirror-symmetrical to the parting line.

Um definierte Kontaktkräfte aufbringen zu können und die Elastizität der Kontaktarme im Bereich der Kontaktkuppen möglichst gering zu halten, ist vorgesehen, dass die Kontaktarme in unmittelbar vor dem die Kontaktkuppen bildenden Umformabschnitt jeweils einen in Richtung Aufnahmeraum vorspringenden Nocken ausbilden.In order to be able to apply defined contact forces and to keep the elasticity of the contact arms in the area of the contact peaks as low as possible, it is provided that the contact arms each form a cam projecting in the direction of the receiving space directly in front of the deformed section forming the contact peaks.

Der Kontakt zeichnet sich weitergehend dadurch aus, die Nocken der Kontaktarme trennliniennah und die Ursprünge der Kontaktarme trennlinienfern angeordnet sind, insbesondere wenn die Kontaktarmbreite im Bereich der Nocken ihr Maximum ausbildet.The contact is further characterized in that the cams of the contact arms are arranged close to the dividing line and the origins of the contact arms are arranged away from the dividing line, in particular when the contact arm width is at its maximum in the area of the cam.

Um beim Stanzvorgang zur Herstellung des Kontaktes eindeutige Bezugsflächen bereitzustellen, ist vorgesehen, dass der Einspannabschnitt eine Ausnehmung, insbesondere ein kreisförmiges Loch aufweist.In order to provide clear reference surfaces during the stamping process for producing the contact, it is provided that the clamping section has a recess, in particular a circular hole.

Des Weiteren betrifft die Erfindung einen Steckverbinder mit einem Steckkontakt nach einem der Ansprüche 1 bis 11, dadurch gekennzeichnet, dass der Kontaktträger zweiteilig mit einer quer zur Steckrichtung liegenden Trennebene ist.Furthermore, the invention relates to a connector with a plug-in contact according to one of claims 1 to 11, characterized in that the contact carrier is in two parts with a parting plane lying transversely to the plug-in direction.

In den Figuren ist ein erfindungsgemäßer Kontakt insgesamt mit der Bezugsziffer 10 versehen.In the figures, a contact according to the invention is given the reference number 10 in its entirety.

Der Kontakt gemäß Erfindung ist Teil eines in den Figuren 1 und 2 dargestellten Steckverbinders 100, der einen Kontaktträgerboden 110 sowie einen Kontaktträgerdeckel 111 aufweist, also mittels eines zweiteiligen Kontaktträgers gebildet ist.The contact according to the invention is part of a figures 1 and 2 shown connector 100, which has a contact carrier base 110 and a contact carrier cover 111, that is formed by means of a two-part contact carrier.

Mehrere nebeneinander angeordnete Kontakte 10 gemäß der Erfindung sind nebeneinander im Kontaktträger gelagert. Hierzu werden sie dicht an dicht gepackt (siehe Figur 2), in den Kontaktträgerdeckel 111 eingeschoben und dort durch Aufsetzen des Kontaktträgerbodens 110 sicher gehalten.Several contacts 10 arranged next to one another according to the invention are stored next to one another in the contact carrier. To do this, they are packed tightly together (see Fig figure 2 ), pushed into the contact carrier cover 111 and held there by placing the contact carrier base 110 securely.

Der Kontaktträgerdeckel, welcher in Figur 3 dargestellt ist, und zwar in einer Ansicht auf seine dem Kontaktträgerboden 110 zugewandte Rückseite, verfügt über Einschuböffnungen 113, die zwei einander gegenüberliegende Kanäle 114 zur Aufnahme von Kontaktarmen 11 und einen Einspannschlitz 115 für einen Einspannabschnitt 15 des Kontaktes 10 bilden. Der Einspannschlitz 115 wird in Einschubrichtung X der Kontakte 10 durch eine Haltewand 116 begrenzt und durch seitliche Stützstege 117 definiert.The contact carrier cover, which in figure 3 is shown, specifically in a view of its rear side facing the contact carrier base 110, has insertion openings 113 which form two opposing channels 114 for receiving contact arms 11 and a clamping slot 115 for a clamping section 15 of the contact 10. The clamping slot 115 is delimited in the insertion direction X of the contacts 10 by a retaining wall 116 and defined by lateral support webs 117 .

Die Figuren 4 und 5 zeigen den erfindungsgemäßen Kontakt 10 für den Steckverbinder 100, welcher in Einschubrichtung X vorne liegend eine Kontaktgabel 13 mit zwei Kontaktarmen 11 aufweist. Die Kontaktarme 11 bilden zwischen sich einen Aufnahmeraum 14 aus, in welchen ein nicht dargestellter Gegenkontakt eintauchen kann. An die Kontaktgabel 13 schließt sich ein Einspannabschnitt 15, dem entgegen der Einschubrichtung X Anschlusselemente 16 zur Anbindung von Versorgungsleitungen entspringen, die hier exemplarisch als Schneidklemmelemente 17 ausgebildet sind.the figures 4 and 5 show the contact 10 according to the invention for the connector 100, which has a contact fork 13 with two contact arms 11 lying at the front in the insertion direction X. The contact arms 11 form a receiving space 14 between them, into which a mating contact (not shown) can dip. The contact fork 13 is followed by a clamping section 15, from which connection elements 16 for connecting supply lines arise counter to the insertion direction X, which are embodied here as insulation displacement elements 17, for example.

Der Kontakt 10 wird durch einen Stanz-/Biegevorgang aus einem Blechstreifen herausgelöst, so dass er sogenannte Walzseiten und Stanzkanten aufweist. Die Walzseite entspricht der Blechoberfläche, die Stanzkanten werden durch das Stanzwerkzeug gebildet, welches den Kontakt aus dem Blechstreifen trennt. Sie laufen im Wesentlichen rechtwinklig zu den Walzseiten.The contact 10 is removed from a metal strip by a stamping/bending process, so that it has so-called rolled sides and stamped edges. The rolling side corresponds to the sheet metal surface, the stamping edges are formed by the stamping tool, which separates the contact from the sheet metal strip. They run essentially at right angles to the rolling faces.

In Einschubrichtung vorne liegend bilden die Kontaktarme 11 Kontaktkuppen 18 aus, die durch Walzseiten des Kontaktes 10 ausgebildet werden. Durch Umformung der Kontaktarme 11 entlang einer Umformlinie U werden die Walzseiten einander zugewandt und weisen in Richtung einer Trennlinie T, die mittig zwischen den Kontaktkuppen 18 angeordnet ist und lotrecht in Richtung des Einspannabschnittes 15 ausgerichtet ist.Lying at the front in the direction of insertion, the contact arms 11 form contact tips 18 which are formed by rolling sides of the contact 10 . By deforming the contact arms 11 along a deformation line U, the roll sides face each other and point in the direction of a parting line T, which is arranged centrally between the contact tips 18 and is aligned perpendicularly in the direction of the clamping section 15 .

Der Einspannabschnitt 15 bildet einen Anschlag 19 aus, der in Einschubrichtung X vorne liegend in den Aufnahmeraum 14 hineinragt und von einer entsprechend ausgerichteten Stanzkante des Einspannabschnitts 15 ausgebildet ist. Dieser Anschlag 19 begrenzt in Zusammenwirken mit der Haltewand 116 des Kontaktträgerdeckels 111 (siehe Figur 3) den Einschubweg des Kontaktes 10 in den Kontaktträgerdeckel 111.The clamping section 15 forms a stop 19 which, lying at the front in the insertion direction X, protrudes into the receiving space 14 and is formed by a correspondingly aligned punched edge of the clamping section 15 . This stop 19 limits in cooperation with the retaining wall 116 of the contact carrier cover 111 (see figure 3 ) the insertion path of the contact 10 into the contact carrier cover 111.

Die Walzseiten des Einspannabschnitts 15 stützen sich im Kontaktträgerdeckel 111 an den Stützstegen 117 ab, um ein seitliches Verkippen des Kontaktes 10 im Kontaktträger zu verhindern.The rolling sides of the clamping section 15 are supported in the contact carrier cover 111 on the support webs 117 in order to prevent the contact 10 from tilting sideways in the contact carrier.

Die Kontaktarme 11 entspringen dem Einspannabschnitt 15. Im Bereich des Ursprungs der Kontaktarme 11 im Einspannabschnitt 15 ist letzterer mit einem Freischnitt 20 versehen, wodurch der Anschlag 19 in den Aufnahmeraum 14 hineinragend ausgeformt ist.The contact arms 11 originate from the clamping section 15. In the region of the origin of the contact arms 11 in the clamping section 15, the latter is provided with a cutout 20, as a result of which the stop 19 is formed so as to protrude into the receiving space 14.

Der jeweilige Kontaktarm 11 selbst ist mit einem Ausschnitt 21 versehen. Dieser Ausschnitt 21 verringert die orthogonal zur Trennlinie T gemessene Kontaktarmbreite. Der jeweilige Freischnitt 20 des Einspannabschnittes 15 und der jeweilige Ausschnitt des Kontaktarms 11 sind durch eine gemeinsame Teilkreislinie geschaffen. In Figur 4 ist zur Verdeutlichung der Teilung von Freischnitt 20 und Ausschnitt 21 exemplarisch und ohne Anspruch auf eine konstruktiv korrekt dargestellte Lage ein Trennstrich S eingezeichnet.The respective contact arm 11 itself is provided with a cutout 21 . This cutout 21 reduces the width of the contact arm measured orthogonally to the dividing line T. FIG. The respective free cut 20 of the clamping section 15 and the respective cutout of the contact arm 11 are created by a common pitch circle line. In figure 4 a dividing line S is drawn in to illustrate the division of cutout 20 and cutout 21 as an example and without claim to a structurally correct position.

Der jeweilige Freischnitt 20 im Ursprungsbereich der Kontaktarme 11 im Einspannabschnitt 15 vergrößert die effektive Länge des Kontaktarms, was insbesondere im Hinblick auf dessen Elastizität im Ursprungsbereich wesentlich ist. Darüber hinaus wird die Elastizität es Kontaktarms 11 in seinem Ursprungsbereich durch den jeweiligen Ausschnitt 21 und den damit verbundenen Materialabtrag erhöht.The respective free cut 20 in the area of origin of the contact arms 11 in the clamping section 15 increases the effective length of the contact arm, which is particularly important with regard to its elasticity in the area of origin. In addition, the elasticity of the contact arm 11 in its original area is increased by the respective cutout 21 and the associated removal of material.

Wie vorne bereits angeklungen, gibt der Freischnitt 20 erhöhte Freiheiten im Hinblick auf die Kontaktausgestaltung. Je nach Anforderung kann der Kontaktarm 11 verkürzt werden, was zu einer verkürzten Bauform des Steckverbinders 100 führen kann. Es ist jedoch ebenso möglich, durch eine Verlängerung des Kontaktarms 11 durch den Freischnitt 20 die Elastizität des Kontaktarms 11 allein durch seine größere Längenausdehnung zu verlängern.As already mentioned above, the cut-out 20 gives increased freedom with regard to the design of the contacts. Depending on the requirements, the contact arm 11 can be shortened, which can lead to a shortened design of the connector 100. However, it is also possible, by lengthening the contact arm 11 through the cutout 20, to lengthen the elasticity of the contact arm 11 solely due to its greater length extension.

Unabhängig vom Freischnitt 20 gewährt der Ausschnitt 21 ebenfalls Möglichkeiten, die Elastizität des jeweiligen Kontaktarms 11 zu erhöhen.Regardless of the cutout 20, the cutout 21 also provides opportunities to increase the elasticity of the respective contact arm 11.

Die Elastizität der Kontaktarme 11 ist erheblich für die im Bereich der Kontaktkuppen 18 auf einen nicht dargestellten Gegenkontakt, wie Leiterkarte oder Kontaktmesser, aufgebrachten Andruckkräfte. Letztere sind im Hinblick auf elektrische wie mechanische Eigenschaften wichtig und müssen wohldosiert erzeugt bei der Gestaltung des Kontaktarms 11 berücksichtigt werden.The elasticity of the contact arms 11 is significant for the pressure forces applied in the area of the contact tips 18 to a mating contact, not shown, such as a printed circuit board or contact blade. The latter are important in terms of both electrical and mechanical properties and must be generated in a well-dosed manner when designing the contact arm 11.

Die Erfindung schlägt deshalb weiterhin vor, der quer zur Trennlinie T gemessene Kontaktarmbreite über die Kontaktarmlänge hinweg zu variieren. Hierzu weist jeder Kontaktarm 11 eine gestufte Außenkontur A sowie eine gestufte Innenkontur I auf. Die Konturen A, I können theoretisch symmetrisch zueinander ausgebildet sein, durch eine Asymmetrie zwischen den Konturen A, I lässt sich jedoch die Kontaktarmbreite definiert variieren, so dass Zonen größerer und geringerer Elastizität entstehen. Hierdurch können die Elastizitätsspannungen im Kontaktarm 11 definiert an die im Bereich der Kontaktkuppen 18 erforderlichen Andruckkräfte angepasst werden.The invention therefore further proposes varying the contact arm width measured transversely to the separating line T over the contact arm length. For this purpose, each contact arm 11 has a stepped outer contour A and a stepped inner contour I. The contours A, I can theoretically be formed symmetrically to one another, but the width of the contact arm can be varied in a defined manner by means of an asymmetry between the contours A, I, so that zones of greater and lesser elasticity arise. As a result, the elastic stresses in the contact arm 11 can be adapted in a defined manner to the pressing forces required in the area of the contact tips 18 .

Beim vorliegenden Kontakt 10 wird eine besonders steife Ausbildung der Kontaktarme in einem den Kontaktkuppen 18 bzw. Umformlinie U unmittelbar nachgeordneten Bereich durch das Ausbilden noch Nocken 22 sichergestellt. Hier erreicht die Kontaktarmbreite durch einen Vorsprung in Richtung Trennlinie T ein Maximum und somit besonders geringe Elastizitätswerte.In the case of the present contact 10, a particularly stiff design of the contact arms in a region immediately downstream of the contact tips 18 or forming line U is ensured by the design of cams 22. Here the width of the contact arm reaches a maximum due to a projection in the direction of the separating line T and thus particularly low elasticity values.

Zusammenfassend zeigt die Erfindung Lösungen auf, wie Bauraum minimierend der Kontakt in seiner in Steckrichtung gemessenen Länge verkürzbar ist, indem durch Rückversetzen des Kontaktarmursprungs am Einspannabschnitt 15 reduziert werden kann. Darüber hinaus zeigt die Erfindung verschiedene Möglichkeiten, verkürzte Kontaktarme 11 in ihrer Elastizität zu beeinflussen.In summary, the invention shows solutions as to how the length of the contact, measured in the direction of insertion, can be shortened while minimizing installation space, in that it can be reduced by moving the origin of the contact arm back on the clamping section 15 . In addition, the invention shows various ways of influencing shortened contact arms 11 in their elasticity.

Die durch den Nocken erhöhte Kontaktarmbreite ermöglicht zudem den sicheren Angriff eines Biegewerkzeuges, welches durch ein Umformen des Stanzteiles um ca. 90° entlang der Umformlinie U die Kontaktkuppen 18 erzeugt.The contact arm width, which is increased by the cam, also enables a bending tool to act reliably, which produces the contact tips 18 by deforming the stamped part by approximately 90° along the deformation line U.

Ein weiterer wesentlicher Vorteil des Kontaktes 10 liegt in der Ausgestaltung seiner Kontaktkuppen 18. Diese kontaktieren durch die Umformung auf den Walzseiten, wohingegen die Kontaktarme mit den Stanzkanten zum Gegenkontakt ausgerichtet sind. So können auf den Walzseiten veredelte Stanzstreifen/-bleche verwendet werden, wobei die Oberflächenveredelung der Walzseite nach dem Umformen die Oberfläche der Kontaktkuppe 18 bildet. Auf eine aufwändige Nachveredelung der Kontakte 10 kann dann verzichtet werden.Another significant advantage of the contact 10 lies in the design of its contact tips 18. These make contact as a result of the deformation on the rolling sides, whereas the contact arms are aligned with the punched edges to the opposite contact. Stamped strips/sheets refined on the rolling sides can thus be used, with the surface finishing of the rolling side forming the surface of the contact tip 18 after forming. A complex post-processing of the contacts 10 can then be dispensed with.
