Abstract
Description
Die Erfindung bezieht sich auf eine Kontaktbuchse für elektrische Steckverbinder gemäß dem Oberbegriff des Anspruches 1.The invention relates to a contact socket for electrical connectors according to the preamble of claim 1.
Eine derartige Kontaktbuchse ist aus der US-PS 5 921 822 bekannt. Diese Bauart
einer Kontaktbuchse zeichnet sich dadurch aus, daß die Kontaktfederbuchse eine
Anzahl durch Ausstanzen aus einem fortlaufenden Streifen eines Kontaktmaterials
gebildete streifenförmige Kontaktierungsmittel, die untereinander durch zwei jeweils
zu einer sechseckigen Querschnittsform abgewinkelte Randstreifen verbunden
sind, aufweist, wobei resultierend aus der hexagonalen Querschnittsform der
Randstreifen nur eine sehr begrenzte Anzahl von Kontaktstreifen verwirklichbar ist,
was naturgemäß eine Verringerung der Kontaktsicherheit mit sich bringt. Im Übrigen
sind auch hier die Kontaktstreifen in bekannter und gebräuchlicher Weise insgesamt
schräg zur Längsachse der Kontaktfederbuchse ausgerichtet.
Aus der US-PS 5 921 822 ist es ferner bekannt die als solche verhältnismäßig labile
Kontaktfederbuchse in einen stabilen Hülsenkörper aufzunehmen, um eine problemlos
verwendbare Kontaktbuchse zu erhalten, ohne zugleich die Kontaktierungseigenschaften
der Kontaktfederbuchse nachteilig zu beeinträchtigen. Die
Festlegung der Kontaktfederbuchse in dem Hülsenkörper erfolgt dabei mittels einer
im Hülsenkörper parallel zu dessen Achse ausgerichtet freigeschnittenen und zum
inneren Ende des Hülsenkörpers hin zeigenden Zunge, welche bestimmungsgemäß
mit einer im Schlitzbereich des inneren Randstreifens der Kontaktfederbuchse
ausgebildeten Ausnehmung in Eingriff gelangen soll. Da hierbei die nach innen
durchgestellte Zunge des Hülsenkörpers in Auszugsrichtung eines mit der Kontaktfederbuchse
zu verbindenden Kontaktstiftes ansteifend ausgebildet bzw. angeordnet
ist, ist ihre mögliche Haltefunktion äußerst begrenzt, da sie beim Lösen von
Steckkontakten auf Biegung insbesondere beansprucht wird.
Aus der US-PS 5 474 479 ist ferner eine Anordnung zur Festlegung einer Kontaktfederbuchse
in einem Hülsenkörper bekannt, welche sich dadurch auszeichnet,
daß die Kontaktfederbuchse radial nach außen abgestellte Endbereiche der Kontaktfedern
aufweist und daß diesen an nach innen durchgestellten Verprägungen
des Hülsenkörpers ausgebildete Widerlagerflächen zugeordnet sind. Dabei sind
zum einen senkrecht zur Hülsenkörperachse ausgebildete Widerlagerflächen an
den nach innen gerichteten Durchstellung entweder überhaupt nicht oder aber nur
mit einem unzumutbar hohen Aufwand erzeugbar und neigen zum anderen die aus
einem dünnwandigen Material bestehenden Kontaktfedern zum Umknicken, so daß
in dieser Weise insgesamt und selbst bei Einsatz eines verhältnismäßig hohen
Herstellungsaufwandes keine sichere Festlegung der Kontaktfederbuchse in dem
Hülsenkörper erreicht werden kann.Such a contact socket is known from US Pat. No. 5,921,822. This type of contact socket is characterized in that the contact spring bush has a number of strip-shaped contacting means formed by punching from a continuous strip of a contact material, which are interconnected by two edge strips angled to a hexagonal cross-sectional shape, resulting in the hexagonal cross-sectional shape of the edge strips Only a very limited number of contact strips can be realized, which naturally brings about a reduction in the contact reliability. Incidentally, here too, the contact strips in a known and customary manner are aligned obliquely to the longitudinal axis of the contact spring bushing.
From US Pat. No. 5,921,822 it is also known to receive as such a relatively unstable contact spring bushing in a stable sleeve body in order to obtain a contact socket which can be used without problems, without adversely affecting the contacting properties of the contact spring bushing at the same time. The determination of the contact spring bushing in the sleeve body is effected by means of a sleeve body parallel to the axis aligned cut and the inner end of the sleeve body facing tongue, which is intended to engage with a formed in the slot portion of the inner edge strip of the contact spring socket recess. Since in this case the inserted inwardly tongue of the sleeve body in the extension direction of a contact spring to be connected to the contact pin pin is formed or arranged stiffening, their possible holding function is extremely limited, since it is particularly stressed when loosening plug contacts on bending.
From US-PS 5,474,479 an arrangement for fixing a contact spring bushing in a sleeve body is also known, which is characterized in that the contact spring bushing radially outwardly parked end portions of the contact springs and that this assigned to inwardly enforced stampings of the sleeve body formed abutment surfaces are. In this case, perpendicular to the sleeve body axis formed abutment surfaces of the inwardly directed position either not at all or only with an unreasonable high cost generated and tend to the other consisting of a thin-walled material contact springs to kinking, so that in total and in this way Use of a relatively high production costs no secure fixing of the contact spring bush in the sleeve body can be achieved.
Der Erfindung liegt daher die Aufgabe zugrunde eine preisgünstig herstellbare Kontaktbuchse der im Oberbegriff des Anspruches 1 beschriebenen Bauart für elektrische Steckverbinder aufzuzeigen, welche auf der einen Seite eine sichere Verankerung der Kontaktfederbuchse in dem stabilen Hülsenkörper gewährleistet und auf der anderen Seite auch in der mechanischen Serienfertigung leicht zu verwirklichen ist.The invention is therefore the object of an inexpensive producible Contact socket of the type described in the preamble of claim 1 for show electrical connectors, which on the one hand a secure Ensuring anchoring of the contact spring bushing in the stable sleeve body guaranteed and on the other hand also in the mechanical mass production easy to is to realize.
Diese Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst.
Vorteilhafte Weiterbildungen und zweckmäßige Ausgestaltungen sind in den Unteransprüchen
angegeben.
Die erfindungsgemäß rein formschlüssige Verbindungsweise gestattet die rein mechanisch-formschlüssige
Festlegung der Kontaktfederbuchse im stabilen Hülsenkörper
eine einfache Herstellung der Kontaktbuchse insgesamt unter ausschließlicher
Anwendung von Schneid-und Formwerkzeugen, was einer Fertigung der
Kontaktbuchsen aus fortlaufenden Materialstreifen sehr entgegenkommt, insbesondere
dahingehend, daß mittels eines Stanz-und/oder Schneidwerkzeuges aus
einem fortlaufenden Materialstreifen mit einem Crimpteil zum Anschluß der Kontaktbuchse
an einen Einzelleiter einteilig Köntaktfederbuchsen freigeschnitten und
freigestanzt und anschließend bereichsweise mehr oder minder vollständig eingerollt
werden können, in der Weise, daß die die Kontaktfederbuchsen bildenden
Bereiche der Freischnitte zu einem Zylinderkörper eingerollt und die die Crimpteile
bildenden Bereiche der Freischnitte lediglich zu einem beispielsweise U-förmigen
Profilquerschnitt gebogen werden können. Die solcherart vorgefertigten Kontaktfederbuchsen
werden dann unbeschadet der Beibehaltung ihrer Verbindung mit einem
Transportstreifen in einer mechanisch herstellbaren, formschlüssigen Weise
durch gegenseitiges Verkrallen oder Verzahnen von Freischnitten und Widerlagern
mit ihrerseits durch Ablängen und Einrollen eines Blechmatterials vorgefertigten
stabilen Hülsenkörpern zu einer brauchbaren Kontakthülse verbunden, wobei die
Freischnitte vorzugsweise aber nicht ausschließlicherweise in dem stabilen Hülsenkörper
und die Widerlager entsprechend an der Kontaktfederbuchse angeordnet
bzw. ausgebildet sind. Selbstverständlich liegt auch die Umkehrung dieser
wechselweisen Anordnung von Freischnitten und Widerlagern im Bereich der vorliegenden
Erfindung.This object is achieved by the features specified in claim 1. Advantageous developments and expedient embodiments are specified in the dependent claims.
The present invention purely positive connection allows the purely mechanical-form-fitting determination of the contact bushing in the stable sleeve body a simple production of the contact socket as a whole with the exclusive use of cutting and forming tools, which very much accommodates a production of the contact sockets of continuous strips of material, in particular to the effect that by means of a punch -and / or cutting tool from a continuous strip of material with a crimp for connecting the contact socket to a single conductor one-piece Köntaktfederbuchsen cut and punched free and then partially more or less completely rolled, in such a way that the contact spring bushing forming areas of the free cuts to a cylinder body rolled up and the crimping parts forming areas of the free cuts can be bent only to an example U-shaped profile cross-section. The thus prefabricated contact spring bushes are then without prejudice to the maintenance of their connection to a transport strip in a mechanically producible, positive manner by mutual Verkrallen or teeth of cutouts and abutments in turn by cutting and rolling a Blechmatterials prefabricated stable sleeve bodies connected to a useful contact sleeve, wherein the free cuts Preferably, but not exclusively in the stable sleeve body and the abutment are arranged or formed according to the contact spring bushing. Of course, the reverse of this alternate arrangement of cutouts and abutments is also within the scope of the present invention.

Diese Ausbildung ist insbesondere dort von besonderem Vorteil, wo im Weiteren vorgesehen ist, daß die beiden im Hülsenkörper freigeschnittenen Zungen gegeneinander zeigend ausgerichtet und jede der beiden Zungen in einen der beiden Längsränder des den Hülsenkörper bildenden Blechmaterialzuschnittes auslaufend freigeschnitten ist. An advantageous design of the positive connection of the contact spring socket with the stable sleeve body is that in which the free End of the contact socket opposite edge strip of the contact spring bushing arranged window recess has a rectangular planform and in the sleeve body two opposing and angled inward Tongues are cut free, which with the narrow sides of the window recess in positive engagement. This training is especially there of particular advantage, where it is further provided that the two in the sleeve body aligned tongues aligned against each other and each of the two tongues in one of the two longitudinal edges of the sleeve body forming Sheet material blank is cut open expiring.
