Description

Die vorliegende Erfindung betrifft ein Crimpwerkzeug zum Crimpen von Crimpkontakten, insbesondere von Halteschutzbuchsen, mit einem Grundkörper, einem dem Grundkörper zugeordneten Anpressstempel und einem dem Grundkörper zugeordneten Amboss und/oder Schnittblock, wobei mindestens ein Crimpkontakt zum Crimpen zwischen dem Anpressstempel und dem Amboss anordenbar ist.The present invention relates to a crimping tool for crimping crimp contacts, in particular holding protective bushes, with a base body, a pressing body associated with the base body and the base body associated anvil and / or cutting block, wherein at least one crimp contact for crimping between the pressure punch and the anvil can be arranged.

Crimpwerkzeuge der eingangs genannten Art sind aus der Praxis bekannt und existieren In den unterschiedlichsten Ausführungsformen. Bei dem Crimpen von Crimpkontakten, d.h. beim Zusammenfügen von Crimpkontakten mit Leitern ist es wesentlich, dass die Leiter ohne mechanische Beeinträchtigung vercrimpt werden.Crimping tools of the type mentioned are known from practice and exist in a variety of embodiments. When crimping crimp contacts, i. When joining crimp contacts to conductors, it is essential that the conductors be crimped without mechanical interference.

In der Praxis hat sich gezeigt, dass beim Einsatz im Kraftfahrzeugbereich große Probleme mit Leitungsverbindungen bei Crimpverbindungen auftreten können. Bei diesen mechanischen Crimpverbindungen können zwei Ursachen zu Fehlern führen. Zum einen verändern die Crimpverbindungen durch Temperaturwechsel, mechanische Beanspruchungen und ständige Vibrationen ihre Übergangswiderstände. Zum anderen wurden durch die Vielfalt der Anforderungen immer höhere Polzahlen bei den Vielfachsteckverbindungen gefordert. Die Kontakte wurden immer kleiner in ihren Dimensionen und die Steckkräfte der Kontakte wurden immer weiter verringert. Hierdurch konnten die Anzahlen an Durchgängen in den Vielfachsteckverbindungen bei gleichzeitig guter Steckbarkeit erhöht werden.In practice, it has been found that when used in the automotive sector, large problems with cable connections can occur in crimp connections. With these mechanical crimp connections, two causes can lead to errors. On the one hand, the crimp connections change their contact resistance due to temperature changes, mechanical stresses and constant vibrations. On the other hand, due to the variety of requirements, ever higher numbers of poles were required for multiple plug connections. The contacts became smaller and smaller in their dimensions and the insertion forces of the contacts were reduced further and further. As a result, the number of passes in the multi-pin connectors with good plug-in capability could be increased.

In langen Versuchsreihen wurde von Kraftfahrzeugherstellern herausgefunden, dass bei diesen Vielfachsteckverbindungen kurze, kaum wahrnehmbare Kontaktunterbrechungen auftreten können. Diese Kontaktunterbrechungen führen zu vielen Fehlern von Fehlinformationen bis zu Totalausfällen im Bereich der Elektroniksysteme.In long series of tests, it has been found by motor vehicle manufacturers that short, barely perceptible contact interruptions can occur with these multiple plug connections. These interruptions in contact lead to many errors of misinformation up to total failures in the field of electronic systems.

Als Konsequenz hieraus wurde ein Verbindungssystem entwickelt, das diese beiden Schwachpunkte ausschaltet. Dabei wird das Ende einer abisolierten Litze flach gepresst und gleichzeitig zur Lasche verschweißt. Danach wird die Lasche in eine Halteschutzbuchse mit definiertem Überstand gesteckt und am überstehenden Ende eingerollt. Eine solche Halteschutzbuchse lässt sich vergleichsweise kraftlos auf einen Kontaktstift stecken. Dabei werden mittels eines Exzenters und einer Stahlfeder in der Halteschutzbuchse die Lasche gegen den Kontaktstift gepresst. Somit werden die beiden oben beschriebenen Schwachpunkte der Crimpverbindung einfach übersprungen bzw. irrelevant.As a consequence, a connection system has been developed which eliminates these two weak points. The end of a stripped strand is pressed flat and simultaneously welded to the tab. Thereafter, the tab is inserted into a retaining sleeve with a defined projection and rolled up at the protruding end. Such a retaining sleeve can be comparatively powerless stuck on a contact pin. The tab is pressed against the contact pin by means of an eccentric and a steel spring in the retaining sleeve. Thus, the two weak points of the crimp connection described above are simply skipped or irrelevant.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein zur Herstellung der neu entwickelten Verbindung geeignetes Crimpwerkzeug anzugeben, mit dem die neuartigen Verbindungen zwischen einer Litze und einer Halteschutzbuchse auf einfache Weise hergestellt werden können.The present invention has for its object to provide a crimping tool suitable for the production of the newly developed compound, with which the novel connections between a stranded wire and a retaining sleeve can be produced in a simple manner.

Die voranstehende Aufgabe wird durch ein Crimpwerkzeug mit den Merkmalen des Patentanspruchs 1 gelöst. Danach ist das Crimpwerkzeug der eingangs genannten Art derart ausgestaltet und weitergebildet, dass dem Amboss und/oder dem Schnittblock ein Kontaktniederhalter zugeordnet ist.The above object is achieved by a crimping tool having the features of patent claim 1. Thereafter, the crimping tool of the type mentioned is designed and further developed such that the anvil and / or the cutting block is associated with a Kontaktniederhalter.

Bei der Herstellung der Verbindung zwischen der Litze und beispielsweise einer Halteschutzbuchse wird das zur Lasche ausgebildete Ende des Leiters in die Halteschutzbuchse eingeführt und das durchstehende Ende der Lasche umgelegt und eingerollt. Des Weiteren werden vorzugsweise gleichzeitig der Draht und die Isolation vercrimpt. Die Crimpverbindung hat in diesem Fall nur eine Haltefunktion und ist nicht für die elektrische Verbindung verantwortlich.When making the connection between the strand and, for example, a retaining sleeve, the end of the conductor formed to the tab is inserted into the retaining sleeve and folded over the end of the tab and rolled up. Furthermore, preferably the wire and the insulation are crimped simultaneously. The crimp connection in this case only has a holding function and is not responsible for the electrical connection.

Die ganze Verarbeitung erfolgt sehr schnell und sicher, wobei hier Zeiten von weniger als 1,3 Sekunden für die Herstellung des Kontakts erreicht werden. Die Einführung des Leiters in die Halteschutzbuchse erfolgt sowohl beim Handarbeitsplatz als auch bei der vollautomatischen Verarbeitung völlig sicher.All processing is very fast and secure, with times of less than 1.3 seconds to make contact. The introduction of the conductor into the retaining sleeve takes place completely safely both at the manual workstation and during fully automatic processing.

Bei einer vorteilhaften Ausgestaltung weist der Kontaktniederhalter einen pneumatischen Antrieb und vorzugsweise einen Pneumatikzylinder auf, der eine sichere Niederhaltung des Crimpkontakts und insbesondere einer Halteschutzbuchse während des gesamten Verarbeitungsvorgangs gewährleistet. Dabei kann der Pneumatikzylinder gleichzeitig eine Federfunktion aufweisen.In an advantageous embodiment, the contact restrainer has a pneumatic drive and preferably a pneumatic cylinder, which ensures a secure holddown of the crimp contact and in particular a retaining sleeve during the entire processing operation. In this case, the pneumatic cylinder can simultaneously have a spring function.

In weiter vorteilhafter Weise könnte der Kontaktniederhalter derart ausgebildet sein, dass er einen Crimpkontakt während eines gesamten Crimpvorgangs auf dem Amboss oder auf dem Schnittblock festhält. Hierdurch ist eine besonders sichere Crimpverbindung gewährleistet.In a further advantageous manner, the contact hold-down could be designed such that it makes a crimp contact during an entire crimping process on the anvil or on the cutting block. This ensures a particularly secure crimp connection.
