Description

Die Erfindung betrifft ein miniaturisiertes Steckkontaktelement nach dem Oberbegriff des Anspruch 1.The invention relates to a miniaturized plug contact element according to the preamble of claim 1.

Derartige Steckkontaktelemente werden üblicherweise in Steckverbindergehäusen in einem vorgegebenen Steckraster angeordnet und nehmen, um eine elektrische Verbindung herzustellen, je einen pfostenartigen, einen quadratischen oder runden Querschnitt aufweisenden Steckkontaktstift auf.Such plug contact elements are usually in connector housings arranged in a predetermined Steckraster and take to make an electrical connection, one each post-like, a square or round cross-section having plug contact pin on.

Ein Steckkontaktelement nach dem Oberbegriff des Anspruchs 1 ist aus dem DE 88 15 178 U1 bekannt.A plug contact element according to the preamble of claim 1 known from DE 88 15 178 U1.

Dieses Steckkontaktelement weist entlang einer Längsachse hintereinander angeordnet einen hinteren Leiterdraht-Anschlußbereich, einen mittleren Federarmbasisbereich und einen vorderen Federarmbereich auf. Der Anschlußbereich umfaßt Leiterdraht- und Isolationskrallen.This plug-in contact element has one behind the other along a longitudinal axis arranged a rear conductor wire connection area, a middle Federarmbasisbereich and a front Spring arm on. The connection area comprises conductor wire and Insulation claws.

Der Anschlußbereich geht in einen rechteckrohrförmigen Kontaktfederarmbasisbereich über. Der rechteckrohrförmige Kontaktfederarmbasisbereich weist einen im wesentlichen quadratischen Querschnitt mit einer Bodenwandung, zwei Seitenwandungen und einer Deckenwandung auf. Von jeweils einem Paar einander benachbarter Stirnkanten zweier Wandungen der rechteckrohrförmigen Basis erstreckt sich ein Paar länglicher Kontaktfedern nach vorne und bilden den Federarmbereich. Die beiden Kontaktfederarme weisen demzufolge einen L-förmigen Querschnitt auf. Die Kontaktfederarme verlaufen zwischen der Basis und einem der Basis gegenüberliegenden freien Ende der Kontaktfederarme im wesentlichen parallel zueinander, so daß der insgesamt quadratische Querschnitt der Kontaktfederarmbasis sich nach vorne fortsetzt. Im Bereich der freien Enden der Kontaktfederarme ist in jeden L-Schenkel nach Art einer Einprägung eine zur Längsachse des Kontaktelements eingewölbte Erhebung ausgebildet. Jede Erhebung bildet eine gleichmäßig gekrümmte, kugelsegment- bzw. kugelabschnittförmige Kontaktfläche. Zwischen den Kontakterhebungen und der Kontaktfederarmbasis weist jede Kontaktfeder entlang der L-Knickkante einen Längsschlitz auf, durch welchen sie im Bereich des Schlitzes geteilt wird. Die L-Schenkel jeder Kontaktfeder sind somit durch einen Federarmanbindungslappenim Bereich der Kontakterhebungen bis zum freien Ende der Kontaktfederarme und auch an der Kontaktfederarmbasis miteinander verbunden.The terminal region goes into a rectangular tubular Kontaktfederarmbasisbereich about. The rectangular tubular contact spring arm base region has a substantially square cross-section with a bottom wall, two side walls and one Ceiling wall on. From one pair each adjacent End edges of two walls of the rectangular tubular base extends a pair of elongated contact springs forward and form the spring arm area. The two contact spring arms point consequently an L-shaped cross-section. The contact spring arms run between the base and one of the base opposite free end of the contact spring arms substantially parallel to each other, so that the total square cross-section the contact spring arm base continues forward. In the area the free ends of the contact spring arms is in each L-leg in the manner of an indentation one to the longitudinal axis of the contact element vaulted elevation formed. Each survey forms a uniformly curved, spherical segment or spherical segmental Contact area. Between the contact elevations and the Contact spring arm base points each contact spring along the L-bend edge a longitudinal slot through which they are in the area of Schlitzes is shared. The L-legs of each contact spring are thus by a Federarmanbindungslappen in the area of the contact elevations to the free end of the contact spring arms and also connected to the Kontaktfederarmbasis together.

Das Steckkontaktelement ist mit einer Schutzhülse versehen, welche einer Überbeanspruchung bzw. Überdehnung der Kontaktfedern entgegenwirken soll, sollte das Steckkontaktelement mit einem überdimensionierten Stift verbunden werden oder ein Stift in Fehlausrichtung in das Steckkontaktelement eingesteckt werden. Diese Schutzhülse ist viereckig rohrförmig mit einem im wesentlichen quadratischen Querschnitt ausgebildet und weist eine Bodenwandung, zwei Seitenwandungen und eine Deckenwandung auf. Aus der Deckenwandung ist eine Verriegelungszunge freigeschnitten, deren freies Ende zum Angreifen an einer Schulter in einem Hohlraum in einem Steckkontaktgehäuse herausgebogen ist. Eine der seitenwandungen ist über die Deckenwandung hinaus verlängert, wodurch eine Kodierplatte gebildet wird, welche eine gewünschte Orientierung beim Einstecken in ein Steckkontaktgehäuse gewährleisten soll. An ihrem vorderen Ende weist die Schutzhülse vier Festhalteflansche auf, welche sich schräg zum Inneren der Schutzhülse bzw. zur Längsachse des Steckkontaktelementes erstrecken. An dem hinteren Ende der Schutzhülse sind Festklammerlaschen angeordnet. Die Schutzhülse wird zur Montage mit ihrem hinteren Ende über die Kontaktfederarme in Richtung zur Federarmbasis aufgeschoben. In montiertem Zustand reicht die Schutzhülse von der Federarmbasis bis über die freien Ende der Kontaktfederarme hinaus.The plug contact element is provided with a protective sleeve, which an overloading or overstretching of the contact springs should counteract, the plug contact element should be connected to an oversized pen or a pen be inserted in misalignment in the plug contact element. This protective sleeve is square tubular with an im formed and has substantially square cross-section a bottom wall, two side walls and a ceiling wall on. From the ceiling wall a locking tongue is cut free, whose free end for engaging a shoulder in a cavity in a plug contact housing is bent out. One of the side walls is extended beyond the top wall, whereby a coding plate is formed, which is a desired orientation when plugged into a plug contact housing should ensure. At its front end, the Protection sleeve four retaining flanges, which are inclined to the Inside the protective sleeve or to the longitudinal axis of the plug contact element extend. At the rear end of the protective sleeve are Clamp straps arranged. The protective sleeve is for assembly with its rear end over the contact spring arms in the direction pushed to Federarmbasis. In the assembled state, the Protective sleeve from the spring arm base over the free end of the Contact spring arms out.

Bei einem derartigen Steckkontaktelement ist von Nachteil, daß dieses einen hohen Platzbedarf hat und darüber hinaus sehr aufwendig in der Herstellung ist. Die Kontaktfederarme liegen bei derartigen Steckkontaktelementen auf allen vier Seitenflächen eines Steckkontaktstiftes lediglich in Teilbereichen mit den Kontaktfederarmen an.In such a plug contact element is disadvantageous in that this has a lot of space and beyond very expensive is in production. The contact spring arms are included Such plug contact elements on all four side surfaces a plug contact pin only in partial areas with the Contact spring arms on.

Die mangelhafte Kontaktierung wird noch dadurch verstärkt, daß durch die L-förmige Ausführung der Kontaktfederarme in ihrem Endbereich die Kontaktfederarme beim Einstecken eines Kontaktstiftes nicht senkrecht zur Kontaktfläche des Stifts ausweichen, sondern eine diagonale seitliche Ausweichbewegung ausführen müssen. Durch diesen insbesondere von den Seitenbereichen beanspruchten Raumbedarf ist es nicht möglich, mit derartigen Steckkontaktelementen diese engen Steckraster und eine optimale Kontaktierung zu gewährleisten.The defective contact is further enhanced by the fact that by the L-shaped design of the contact spring arms in their End region of the contact spring arms when inserting a contact pin do not dodge perpendicular to the contact surface of the pen, but perform a diagonal lateral evasive movement have to. By this claimed in particular by the side areas Space is not possible with such Plug-in contact elements this tight Steckraster and optimal To ensure contact.

Darüber hinaus ist aus der EP 0 352 871 B1 eine Kastenfeder bekannt. Bei dieser Kastenfeder ist eine Flachgabelfeder mit einer Überfeder kombiniert, welche beide in miniaturisierter Form vorliegen. Die Flachgabelfeder ist als doppelarmige Flachgabelfeder ausgeführt, wobei die Federarme der Flachgabelfeder sowie die Überfederarme in Ost-West-Richtung angeordnet sind und ein Rastfederarm in Nord- oder Südrichtung angeordnet ist. Die Federarmbasis ist bei dieser bekannten Kastenfeder U-förmig ausgebildet.In addition, EP 0 352 871 B1 discloses a box spring known. In this box spring is a flat fork spring with combined an over-spring, both in miniaturized Form present. The flat fork spring is a double-armed flat fork spring executed, wherein the spring arms of the flat fork spring and the over-spring arms are arranged in east-west direction and a Rastfederarm is arranged in the north or south direction. The Federarmbasis is U-shaped in this known box spring educated.

Die Steckkontaktstifte, welche üblicherweise zur Kontaktierung eines derartigen Steckkontaktelementes benutzt werden, sind herstellungsbedingt meist nur auf zwei gegenüberliegenden Seiten nämlich in Nord-Süd-Richtung mit Edelmetall in einer definierten Schichtdicke beschichtet. Die Seiten eines Steckkontaktelementes oder eines Steckkontaktstiftes lassen sich in einer steckseitigen Draufsicht analog zu einer Kompaßrose definieren, wobei die Bodenwandung des Anschlußbereiches des Steckkontaktelementes oder des Steckkontaktstiftes die Südseite definiert und die Seite zu denen die Crimpfahnen weisen bzw. die nach oben offene Seite als Nordseite bezeichnet wird. Folglich bilden die Seitenwandungen die Ost- und Westseite.The plug contact pins, which are usually for contacting such a plug-in contact element are used, are production-related usually only on two opposite sides namely in north-south direction with precious metal in a defined Coated layer thickness. The sides of a plug contact element or a plug contact pin can be in a plug-side Define top view analogous to a compass rose, wherein the Bottom wall of the connection region of the plug contact element or the plug contact pin defines the south side and the Side to which the Crimpfahnen point or open to the top Page is called north side. Consequently, the side walls form the east and west side.

Insbesondere durch die Anlage an einer nicht oder nicht spezifiziert beschichteten (Ost- oder West-) Seitenwand des Stifts ist der Stromübergang nicht optimal.In particular, by investing in a not or not specified coated (east or west) side wall of the pen is the current transition is not optimal.

Außerdem sind die Kontaktfederkräfte nicht optimal.In addition, the contact spring forces are not optimal.

Aus der DE 195 36 264 A1 ist eine Kontaktfeder mit Rasthülse bekannt, bei der zur Befestigung einer als Überfeder dienenden Rasthülse an einer Grundfeder die Rasthülse mit zwei seitlichen, durch Trennschnitte gebildeten Haltezapfen versehen ist, welche in einer Ausnehmung der Federschenkelbasis der Grundfeder eingreifen und um deren Seitenwände nach innen umgebogen sind. Diese bekannte Kontaktfeder weist Kontaktfederarme auf, welche an Decken bzw. Bodenwandungen (Nord/Süd) angeordnet sind, wobei diese Kontaktfederarme von Überfederarmen der Rasthülse, welche ebenfalls in Nord/Südrichtung angeordnet sind, belastet werden. Die Überfederarme sind durch paraboloide Freischnitte aus der Decken- bzw. Bodenwandung der Rasthülse in der Art freigeschnitten, daß sie sich von einer Längskante in Richtung zu einer gegenüberliegenden Längskante erstrecken, wobei sie nach innen eingebogen sind, um auf den Kontaktfederarmen aufzuliegen. Darüberhinaus ist aus der Deckenwandung ein nach oben und hinten weisender Rastfederarm freigeschnitten und nach außen gebogen. Bei diesem bekannten Steckkontaktelement ist von Nachteil, daß sich durch die Ausgestaltung der Überfederarme, insbesondere durch den kurzen wirksamen Federweg sowie die daraus resultierende starke Einbiegung in die Hülse eine ungünstige Federkennlinie ergibt. Darüberhinaus gleiten die Überfederarme bei einer Aufweitung der Federarme quer zur Längsrichtung über deren äußerere oberfläche, wodurch die Kontaktfederkräfte über die Breite der Kontaktfeder nicht konstant sind. Durch die Anordnung des Rastfederarms benachbart zu einem der Überfederarme ist dieser sehr kurz, so daß er nicht sehr weit nach außen vorstehend angeordnet werden kann. Die unmittelbar benachbarte Anordnung eines Überfederarms und eines Rastfederarms an einer einzigen Wandung eines Kontaktfederelements führen darüberhinaus zu Instabilitäten der Überfederhülse.From DE 195 36 264 A1 is a contact spring with latching sleeve known in the serving for fastening a overspring Detent sleeve on a ground spring the detent sleeve with two lateral, provided by separating cuts retaining pin is provided, which engage in a recess of the spring leg base of the base spring and around whose side walls are bent inwards. This known contact spring has contact spring arms, which are arranged on ceilings or bottom walls (north / south), where this contact spring arms of over-spring arms of the locking sleeve, which are also arranged in north / south direction, be charged. The over-spring arms are characterized by parabolic free cuts from the Ceiling or bottom wall of the locking sleeve in the manner of cut, that they are moving from one longitudinal edge towards extend an opposite longitudinal edge, wherein they after are inwardly inflected to rest on the contact spring arms. In addition, from the top wall one up and back pointing latch arm free cut and bent outwards. In this known plug contact element is disadvantageous in that itself by the configuration of the over-spring arms, in particular by the short effective travel and the resulting strong inflection in the sleeve an unfavorable spring characteristic results. Moreover, the over-spring arms slide at one Expansion of the spring arms transversely to the longitudinal direction on the outer surface, whereby the contact spring forces across the width the contact spring are not constant. Due to the arrangement of the Rastfederarms adjacent to one of the over-spring arms is this very short, so he did not project very far outward can be. The immediately adjacent arrangement an over-spring arm and a Rastfederarms on a single Wall of a contact spring element also lead to instabilities the over-spring sleeve.

Aufgabe der Erfindung ist es, ein miniaturisiertes Steckkontaktelement mit zwei Kontaktfederarmen aus einem Blechstanzteil zu schaffen, welches einen geringen, insbesondere geringeren seitlichen Platzbedarf erfordert, so daß bei vorgegebenen kleinen Steckrastern keine Raumnot entsteht und welches einfacher aufgebaut und einfacher herzustellen ist und welches insbesondere auch eine bessere Kontaktierung durch Kontaktierung in Nord-Süd-Richtung sowie optimierte Kontaktfederkräfte mit einem optimierten Stromübergang ermöglicht.The object of the invention is to provide a miniaturized plug contact element with two contact spring arms from a stamped sheet metal part too create, which has a low, especially lower lateral Requires space, so that given small Steckrastern no lack of space arises and which is simpler and easier to manufacture and which in particular also a better contact by contacting in north-south direction as well as optimized contact spring forces with an optimized Electricity transfer possible.

Diese Aufgabe wird durch ein miniaturisiertes Steckkontaktelement mit den Merkmalen des Anspruch 1 gelöst.

Diese Kontaktfederarme können auf der gesamten Breite der jeweiligen Nord- oder Südseite eines Steckkontaktstiftes mit ihren Kontakt- bzw. Gabelfederarmen aufliegen. Um eine noch bessere, optimierte Kontaktkraft zu erreichen, werden die Kontaktfederarme zusätzlich mit Überfederarmen belastet, wobei die Überfederarme ebenfalls in Nord-Süd-Richtung angeordnet sind. Oberhalb eines dieser Überfederarme ist ein Rastfederarm ebenfalls in Nord- bzw. Südrichtung angeordnet, so daß durch den erfindungsgemäßen Verzicht auf an den Seitenwandungen nach außen vorstehende Bauteile eine besonders schmale und platzsparende Bauweise eines Steckkontaktelements erreicht wird.According to the invention, the miniaturized plug contact element only the sides coated in north-south direction a einzusteckenden contact pin opposite contact spring arms on. These contact spring arms can be used on the whole Width of the respective north or south side of a plug contact pin rest with their contact or fork spring arms. Around to achieve an even better, optimized contact force the contact spring arms additionally loaded with over-spring arms, wherein the over-spring arms are also arranged in a north-south direction are. Above one of these over-spring arms is a Rastfederarm also arranged in north or south direction, so that through the waiver of the invention on the side walls after outside projecting components a particularly narrow and space-saving Construction of a plug contact element is achieved.
