The invention relates to a contact element consisting of a contact plate and a contact pin which is integrated in a multifunctional electrical connection arrangement.
Aus dem Stand der Technik sind unterschiedliche elektrische Verbindungsanordnungen zur Übertragung hoher Stromdichten bekannt. Besonders im Automobilbereich finden sich hier zahlreiche Anwendungen. Ein erhöhter Bedarf ist in den letzten Jahren aufgrund der From the prior art, different electrical connection arrangements for transmitting high current densities are known. Especially in the automotive sector there are numerous applications here. There is an increased demand in recent years due to the
Weiterentwicklung und des Ausbaus der Elektromobilität entstanden. Ein wesentlicher Vorteil bei standardisierten elektrischen Verbindungsanordnungen ist die Möglichkeit, dass ein kostenoptimierter Betrieb von Produktionslinien möglich ist. Ein wesentlicher Nachteil bei den herkömmlichen elektrischen Verbindungsanordnungen ist, dass zum Anschluss größerer Kabelquerschnitte der vorhandene Bauraum im Gehäuse häufig nicht ausreicht und deshalb eine vollständig neue Anordnung der Kontakte im Gehäuse umgesetzt werden muss, die typischerweise einen größeren Bauraum benötigt.  Development and expansion of electromobility emerged. A significant advantage of standardized electrical connection arrangements is the possibility that a cost-optimized operation of production lines is possible. A major disadvantage of the conventional electrical connection arrangements is that for the connection of larger cable cross-sections of the available space in the housing is often insufficient and therefore a completely new arrangement of the contacts must be implemented in the housing, which typically requires a larger space.
Der Erfindung liegt deshalb die Aufgabe zugrunde, vorbesagte Nachteile zu überwinden und einerseits ein Kontaktelement und andererseits eine elektrische Verbindungsanordnung dahingehend zu verbessern, dass auch zum Anschluss unterschiedlicher insbesondere größerer Kabelquerschnitte eine vorhandene Steckbuchse verwendet werden kann. Dies ist besonders bei einigen Anwendungen, wie z. B. Fahrzeuganwendungen von zunehmender Bedeutung, da bauraumbedingt die Größe der Steckbuchse nicht geändert werden kann. The invention is therefore an object of the invention overcome above-mentioned disadvantages and on the one hand to improve a contact element and on the other hand an electrical connection arrangement to the effect that also for connecting different particular larger cable cross-sections an existing socket can be used. This is especially in some applications, such. As vehicle applications of increasing importance, because of space constraints, the size of the socket can not be changed.
Diese Aufgabe wird durch die Merkmalskombination gemäß Patentanspruch 1 gelöst. This object is achieved by the feature combination according to claim 1.

Das erfindungsgemäße Kontaktelement besteht aus einer Kontaktplatte und einem von der Kontaktplatte hervorstehenden und außermittig auf der Kontaktplatte angeordnetem Kontaktpin. Die genannte Anordnung der Kontaktpins auf der Kontaktplatte ermöglicht eine variable In accordance with the invention, therefore, a multifunctional electrical connection arrangement for transmitting medium and high current intensities consisting of a socket with contact openings, a contact carrier, and a plurality of contact elements is preferably provided with a compaction. The contact element according to the invention consists of a contact plate and a contact pin protruding from the contact plate and arranged eccentrically on the contact plate. Said arrangement of the contact pins on the contact plate allows a variable

Hierdurch können auch bei dichter Anreihung der Kontakte dennoch größere Kabelquerschnitte zur Übertragung höherer Stromdichten an den Kontaktplatten angeschlossen werden, ohne dass die die Design of the multifunctional electrical connection arrangement. As a result, larger cable cross-sections for transmitting higher current densities can still be connected to the contact plates even with tight arrays of contacts, without the the
Kontakte aufnehmende Steckbuchse geändert werden muss. Dies ist besonders durch den begrenzten und vorbestimmten Bauraum ein wesentlicher Vorteil gegenüber dem Stand der Technik. Contacts receiving female connector must be changed. This is a significant advantage over the prior art, especially due to the limited and predetermined space.
In einer besonders vorteilhaften Ausgestaltung der Erfindung ist der Kontaktpin des In a particularly advantageous embodiment of the invention, the contact pin of
Kontaktelements orthogonal zu der Kontaktplatte angeordnet. Die multifunktionale elektrische Verbindungsanordnung besteht im Wesentlichen aus der Steckbuchse, den Kontaktelementen, dem Kontaktträger, wobei der Anschlussbereich des Kabels vorzugsweise mittels Contact element arranged orthogonal to the contact plate. The multifunctional electrical connection arrangement consists essentially of the socket, the contact elements, the contact carrier, wherein the connection region of the cable preferably by means of
Kompaktierung geformt ist, so dass eine direkte Verbindung des Kabels an der Kontaktplatte (ohne ein Verbindungselement) möglich ist. Bezüglich der Kontaktplatte und den Öffnungen der Steckbuchse orthogonal angeordnete Kontaktelemente erleichtern zusätzlich das Einstecken in die Öffnung der Steckbuchse. In einer weiteren Ausführung ist vorgesehen, dass der Kontaktträger Vertiefungen (Kavitäten) zur Aufnahme der Kontaktelemente besitzt. Die Kontaktelemente sind an den Kontaktpins innerhalb der Steckbuchse und auf der gegenüberliegenden Seite mit der Kontaktplatte in der genannten jeweiligen Vertiefung des Kontaktträgers gehalten. Zusätzlich sind die einzelnen stromführenden Kontaktelemente voneinander beabstandet und elektrisch isoliert. Insbesondere sind die Kontaktelemente in dem Kontaktträger gehatten und werden als vormontierte Einheit in die Steckbuchse eingesteckt.
