Description

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Kontaktverbindern aus elektrisch leitendem Material für Anschlussvorrichtungen zum Verbinden elektrisch isolierter Leitungsadern, welche Kontaktverbinder eine trennbare Kontaktbrücke aufweisen, mit geschlitzten Endteilen für die Aufnahme von Ader-Enden, wobei von den Endteilen federnde, parallel überbrückende Kontaktzungen abragen, die je am freien Ende eine Kontaktfläche tragen.The present invention relates to a method for producing contact connectors made of electrically conductive material for connecting devices for connecting electrically insulated conductor wires, which contact connectors have a separable contact bridge, with slotted end parts for receiving wire ends, whereby resilient, parallel bridging contact tongues protrude from the end parts that each have a contact surface at the free end.

Kontaktverbinder dieser Art sind beispielsweise durch das EP - Patent 0 370 380 der gleichen Anmelderin bekannt geworden und sind in einer Anschlussvorrichtung, wie Anschlussleiste der Datenkommunikation, sowohl als Trennkontakt wie auch als Durchgangskontakt verwendbar.Contact connectors of this type are known, for example, from EP patent 0 370 380 by the same applicant and are in a connection device, Like terminal block for data communication, can be used both as an isolating contact and as a through contact.

Kontaktverbinder der vorgenannten Art sind bekanntermassen in riesigen Stückzahlen erforderlich, sodass deren Herstellung immense wirtschaftliche Bedeutung zukommt.Contact connectors of the aforementioned type are known to be required in huge numbers, so that their manufacture is of immense economic importance.

Dem vermögen bisherige Herstellungverfahren nicht zu genügen, wo insbesondere eine Mehrzahl Kontaktverbinder in abgelängten Streifen von Hand in das Galvanikbad eingebracht und wieder entfernt werden.The previous production methods are not able to meet this requirement, where in particular a plurality of contact connectors in cut strips are manually inserted into the electroplating bath and removed again.

Aufgabe der vorliegenden Erfindung ist nun eine wesentliche Verbesserung solcher bekannter Verfahren, um die Herstellung der Kontaktverbinder den heutigen Anforderungen entsprechend zu vereinfachen und zu verbilligen.The object of the present invention is now a substantial improvement of such known methods in order to simplify and reduce the cost of manufacturing the contact connectors in accordance with today's requirements.

Dies wird erfindungsgemäss dadurch erreicht, dass die Kontaktverbinder in ihrer Abwicklung und unter Beibehaltung von Randstreifen aus einem Endlos-Materialstreifen herausgestanzt, dann wenigstens teilweise gebogen, dann galvanisiert und dann fertiggebogen werden.This is achieved according to the invention in that the contact connectors are punched out of an endless material strip in their development and while maintaining edge strips, then at least partially bent, then galvanized and then finished bent.

Eine bevorzugte Ausführungsform des erfindungsgemässen Verfahrens besteht dann darin, dass nach dem Herausstanzen, Vorbiegen, Galvanisieren und Fertigbiegen das jeweilige Zwischenprodukt wieder aufgewickelt wird.A preferred embodiment of the method according to the invention then consists in that the respective intermediate product is rewound after punching out, pre-bending, galvanizing and finishing bending.

Erst unmittelbar vor der Bestückung erfolgt dann das Ablängen, was, neben einem Galvanisieren im Durchlaufverfahren, eine weitere Verbesserung in der Lagerhaltung erbringt.The cutting to length occurs only immediately before the assembly, which, in addition to galvanizing in a continuous process, brings about a further improvement in storage.

Hiebei können an den aus einem Endlos-Materialstreifen herausgestanzten und durch mindestens einen Randstreifen gehaltenen Abwicklungen der Kontaktverbinder mindestens die Kontaktflächen der Kontaktzungen vorgebogen oder an den aus einem Endlos-Materialstreifen herausgestanzten und durch mindestens einen Randstreifen gehaltenen Abwicklungen die Kontaktverbinder bis auf eine der Kontaktzungen fertiggebogen werden.In this case, at least the contact surfaces of the contact tongues can be pre-bent on the developments of the contact connectors punched out from an endless material strip and held by at least one edge strip, or the contact connectors can be bent down to one of the contact tongues on the developments punched out of an endless material strip and held by at least one edge strip .

Der mindestens eine Randstreifen wird dann vorzugsweise erst nach oder bei der Bestückung der Anschlussvorrichtung abgetrennt.The at least one edge strip is then preferably cut off only after or when the connecting device is equipped.

Weiter betrifft die vorliegende Erfindung Kontaktverbinder, hergestellt nach dem erfindungsgemässen Verfahren.The present invention further relates to contact connectors produced by the method according to the invention.

Eine beispielsweise Ausführungsform des Verfahrens ist nachfolgend anhand der Zeichnung näher erläutert. Es zeigen:

An example embodiment of the method is explained in more detail below with reference to the drawing. Show it:

in a diagram-like representation a contact connector, to explain the process for its manufacture;
Fig. 2
some contact connectors in their band-shaped development; and
Fig. 3
in a diagram-like representation, the contact connectors produced by the method according to the invention, which are still connected to one another, in the assembly phase on a connecting device.

Der erfindungsgemässe Kontaktverbinder 1 aus elektrisch leitendem Material für Anschlussvorrichtungen zum Verbinden elektrisch isolierter Leitungsadern gemäss Fig. 1 umfasst eine trennbare Kontaktbrücke 2, welche hier in flächig verbreiterte, Aufnahmeschlitze 4 für Ader Enden (nicht gezeigt) aufweisende Endteile 5 übergeht, die sich in zwei wenigstens angenähert parallelen Ebenen gegenüberliegen. Hierbei ragen seitlich der Schenkel 3 von den Endteilen 5 federnde, sich einander gegenüberliegende Kontaktzungen 6,6' ab, die je am freien Ende eine Kontaktfläche 7 tragen, welche unter der Wirkung der Federspannung der Kontaktzungen 6,6' mit vorgegebenem Druck aneinander liegen.The contact connector 1 according to the invention, made of electrically conductive material for connecting devices for connecting electrically insulated line wires according to FIG. 1, comprises a separable contact bridge 2, which in this case merges into end sections 5, which are widened in area and have receiving slots 4 for wire ends (not shown), which at least merge into two are approximately parallel planes. Here, the side of the leg 3 protrude from the end parts 5 resilient, opposing contact tongues 6,6 ', each carrying at the free end a contact surface 7, which lie against each other under the effect of the spring tension of the contact tongues 6,6' with a predetermined pressure.

Auf diese Weise bildet ein solcher Kontaktverbinder 1 einen Durchgangskontakt. Soll dieser hingegen als Trennkontakt Verwendung finden, ist es lediglich erforderlich, den einen Schenke 3 an der Stelle 8 zu trennen.In this way, such a contact connector 1 forms a through contact. On the other hand, if this is to be used as an isolating contact, it is only necessary to separate one leg 3 at point 8.

Zur Herstellung dieser Kontaktverbinder werden die Abwicklungen 1' der Kontaktverbinder zunächst aus einem Endlosband 20 mit einem modularen Abstand gemäss Kontakteabstand der Anschlussvorrichtung 10 (Fig.3) herausgestanzt, wobei Randstreifen 21 die Abwicklungen zusammenhalten.To manufacture these contact connectors, the developments 1 'of the contact connectors are first of all made from an endless belt 20 with a modular spacing punched out according to the contact distance of the connection device 10 (FIG. 3), edge strips 21 holding the developments together.

An den aus einem Endlos-Materialstreifen 20 herausgestanzten und durch mindestens einen Randstreifen 21,21' gehaltenen Abwicklungen 1' der Kontaktverbinder 1 werden dann mindestens die Kontaktflächen 7 der Kontaktzungen 6,6' vorgebogen, wie das Fig. 2 erkennen lässt, oder es werden die Kontaktverbinder bis auf die Kontaktzunge 6 fertiggebogen, wie das Fig. 3 zeigt.At least the contact surfaces 7 of the contact tongues 6, 6 'are then pre-bent on the unwindings 1' of the contact connectors 1 which are punched out of an endless material strip 20 and held by at least one edge strip 21, 21 ', as can be seen in FIG. 2, or they are the contact connectors bent to the contact tongue 6, as shown in FIG. 3.

Der so bereitete Endlos-Materialstreifen wird dann im Durchlaufverfahren galvanisiert.The endless strip of material thus prepared is then galvanized in a continuous process.

Dann können die Kontaktverbinder fertiggebogen werden.Then the contact connectors can be bent.

Danach kann vom aufgewickelten Endprodukt die Bestückung der Anschlussvorrichtung 10, hier Anschlussleiste mit Kammleisten 14 und mit Nuten 15 für die Leiteradern (nicht gezeigt), unter Ablängung und Wegnahme der Randstreifen 21,21' erfolgen.Thereafter, the connection device 10, here the terminal strip with comb strips 14 and with grooves 15 for the conductor wires (not shown), can be fitted from the wound end product, with the edge strips 21, 21 'being cut to length and removed.

Erfindungswesentlich ist hierbei, dass nach dem Herausstanzen, Vorbiegen, Galvanisieren und Fertigbiegen das jeweilige Zwischenprodukt wieder aufgewickelt wird.It is essential to the invention that the respective intermediate product is rewound after punching out, pre-bending, galvanizing and finishing bending.

Es wird Schutz beansprucht wie folgt:Protection is claimed as follows:
