"Vorrichtung zur Herstellung von elektrischen Kontaktierungen""Device for making electrical contacts"

Die Erfindung bezieht sich auf eine Vorrichtung zur Herstellung von elektrischen Kontaktierungen, insbesondere von lötfreien Verbindungen zwischen Einzelleitern und Steckern oder Buchsen, mit einer automatischen Anschlagnaschine.The invention relates to a device for producing electrical contacts, in particular from solderless connections between single conductors and plugs or sockets, with an automatic stop machine.

Die seit vielen Jahren sowohl in der Kraftfahrzeug-Industrie als auch in der allgemeinen Elektrotechnik angewandten Kontaktierungssysteme mit lötfreier Anschlagtechnik - Quetschoder Anpreßverfahren, beispielweise "wire-wrap"-Verfahren geben infolge mangelnder Zuverlässigkeit der Anschlagtechnik häufig Grund zu Beanstandungen. Die Ursache hierfür liegt insbesondere darin, daß die Anschlagautomaten beim Anschlagen unterschiedlicher Leitungsquerschnitte nicht auf die richtigen Anschlagwerkzeuge umgestellt werden, oder aber, daß die Anschlagwerkzeuge bei Abnutzung nicht sorgfältig kontrolliert werden und somit der Festsitz der angeschlagenen Leiter nicht immer gewährleistet ist. Dies führt zu erhöhtem Spannungeabfall und kann zu einem frühzeitigen Ausfall der Kontaktierungsstelle führen, was dadurch begünstigt wird, daß eine lötfrei angeschlagene Verbindung bezüglich ihrer Qualität nicht zerstörungsfrei geprüft werden kann. Auch gegen Korrosion und Oxydation ist eine solche Verbindung nicht sicher.Has been in the automotive industry for many years as well as contacting systems used in general electrical engineering with solderless stop technology - squeezing or pressing processes, for example "wire-wrap" processes due to the lack of reliability of the lifting technology, this is often a cause for complaint. The reason for this lies especially in the fact that the automatic stop when hitting different cable cross-sections are not on the correct Stop tools are switched, or that the stop tools are not carefully checked in the event of wear and thus the tight fit of the attached ladder is not is always guaranteed. This leads to an increased voltage drop and can lead to premature failure of the contacting point lead, which is favored by the fact that a solderless struck connection is not non-destructive with regard to its quality can be checked. Such a connection is also not safe against corrosion and oxidation.

Lötverbindungen wurden wegen ihrer thermischen Empfindlichkeit und der größeren Herstellungszeit und -kosten durch die genannte lötfreie Anschlagtechnik ersetzt und Schweißverbindungen schieden wegen Versprödung der Schweißstelle und erhöhter Druchgefahr ebenfalls aus.Solder connections were made because of their thermal sensitivity and the greater manufacturing time and costs replaced by said solderless stop technology and welded connections were also ruled out due to the embrittlement of the weld and the increased risk of damage.

Es ist Aufgabe der Erfindung, eine Vorrichtung zu schaffen, welche preiswert und schnell eine qualitative und dauerhafte Kontaktierung herzustellen in der Lage ist.It is the object of the invention to create a device which is inexpensive and quick to provide a qualitative and durable Is able to establish contact.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß eine mit der Anschlagmaschine verbundene Schweißvorrichtung vorgesehen ist, welche vor, mit oder nach dem Anschlage die zu verbindenden Teile verschweißt. Der Vorteil einer solchen Vorrichtung nach der Erfindung besteht darin, daß damit eine einwandfreie elektrische Verbindung durch ein absolut homogenes Gefüge entsteht, welches korrosive Bestandteile, wie Salzwasser usw., nicht eindringen läßt. Die Versprödung der Schweißstelle wird durch die Quetschstellen der Anschlagverbindung entschärft; diese wirkt wie eine Biege- und Zugentlastung für die Schweißstelle. Eine erfindungsgemäße Vorrichtung kann je nach Konstruktion des verwendeten Anschlagautomaten auf verschiedene Weise aufgebaut sein und bedarf zu ihren Verständnis keiner weiteren Erläuterungen oder Darstellung.This object is achieved in that a With the stop machine connected welding device is provided, which before, with or after the stop to connecting parts welded. The advantage of such a device according to the invention is that so that a flawless electrical connection is created through an absolutely homogeneous structure, which contains corrosive components such as Salt water, etc., does not allow it to penetrate. The embrittlement of the welding point is caused by the pinch points of the stop connection defused; this acts like a bending and strain relief for the welding point. A device according to the invention can be constructed in different ways depending on the construction of the automatic fence used and needs to their Understanding of any further explanation or representation.

In der Zeichnung sind verschiedenartige geschweißte Quetschverbindungen dargestellt, wobei die Schweißstellen als dicke Punkte angedeutet sind und jeweils so liegen, daß die Quetschverbindung noch als Zug- und Biegeentlastung wirken kann.Various types of welded crimp connections are shown in the drawing shown, the welds are indicated as thick points and each lie so that the crimped connection can still act as tension and bending relief.
