Description
Stand der TechnikState of the art
Die Erfindung betrifft einen Leiter mit Kontaktteil nach dem Oberbegriff des Anspruchs 1.The The invention relates to a conductor with contact part according to the preamble of claim 1.
Angesichts ständig steigender Rohstoffkosten gewinnt Aluminium als Ersatzwerkstoff für Kupfer zur Verwendung bei elektrischen Leitern und Kabeln mehr und mehr an Bedeutung. Für die Anwendung in Kraftfahrzeugen ist insbesondere auch die mit Aluminiumleitern erzielbare Gewichtseinsparung von rund 40% im Vergleich zu Kupferleitungen von großem Interesse, da mit leichteren Fahrzeugen Kraftstoff gespart werden kann. Die Herstellung einer betriebsicheren, dauerfesten und elektrisch gut leitenden Verbindung eines aus Aluminium bestehenden Kabels mit einem Kontaktstück, wie beispielsweise einem Kabelschuh oder einem Polstück, ist eine große Herausforderung, da sich auf metallisch blankem Aluminium in kürzester Zeit eine vergleichsweise harte, elektrisch isolierende Oxidschicht bildet.in view of constantly Rising raw material costs win aluminum as a substitute material for copper to Use on electrical conductors and cables more and more Importance. For the application in motor vehicles is especially those with aluminum conductors achievable weight savings of around 40% compared to copper cables of great Interest because fuel is saved with lighter vehicles can. The production of a safe, durable and electric good conductive connection of an existing aluminum cable with a contact piece, such as a cable lug or a pole piece is a big Challenge, since on bare metal in the shortest time Time a comparatively hard, electrically insulating oxide layer forms.

Technische AufgabeTechnical task
Der Erfindung liegt die Aufgabe zugrunde, eine betriebsichere, dauerfeste und elektrisch gut leitende Verbindung eines aus Aluminium bestehenden Kabels mit einem Kontaktstück, wie beispielsweise einem Stift, einer Buchse, einem Kabelschuh oder einem Polstück, zu schaffen, die besonders kostengünstig herstellbar ist.Of the Invention is based on the object, a reliable, durable and electrically conductive connection of a cable made of aluminum with a contact piece, such as a pin, a socket, a cable lug or a pole piece, to create, which is particularly inexpensive to produce.
Diese Aufgabe wird durch die in Anspruch angegebene Erfindung gelöst.These The object is solved by the invention defined in claim.
Vorteile der ErfindungAdvantages of the invention
Die Erfindung geht von der Erkenntnis aus, dass eine dauerfeste, elektrisch gut leitende und daher besonders betriebssichere Verbindung eines elektrischen Leiters mit einem Kontaktteil durch ein zwischen dem Kontaktteil und dem Leiter angeordnetes Anschlussteil ermöglicht wird, das mindestens zwei Crimpverbindungen umfasst, die metallische Bereiche des Leiters umschließen.The Invention is based on the recognition that a durable, electrically good conductive and therefore particularly reliable connection of an electrical Ladder with a contact part through a between the contact part and the conductor arranged connecting part is made possible, the at least two Crimp connections includes the metallic areas of the conductor enclose.
Vorteilhaft dient dabei eine der mindestens zwei Crimpverbindungen für eine Zugentlastung des mit dem Kontaktteil bestückten Leiters, während eine zweite der mindestens zwei Crimpverbindungen vorwiegend der elektrischen Kontaktierung des Leiters dient. Die letztgenannte Crimpverbindung ist dazu stärker verpresst als die erstgenannte Crimpverbindung, wodurch auf dem Leiter oder seinen Bestandteilen gebildete Oxidschichten durchdrungen werden können.Advantageous serves one of the at least two crimp connections for a strain relief of the equipped with the contact part Conductor, while a second of the at least two crimp connections predominantly the electrical contacting of the conductor is used. The latter Crimp connection is stronger pressed as the former Crimpverbindung, whereby on the Conducted conductor or its constituents formed oxide layers can be.
In einer Ausführungsvariante der Erfindung sind die die metallischen Bereiche des Leiters umschließenden Crimpverbindungen mit Abstand voneinander angeordnet. Dies erleichtert den Ansatz unterschiedlicher Crimpwerkzeuge, um die voneinander abweichende Verpressung zu erzielen.In an embodiment variant The invention relates to the crimp connections enclosing the metallic regions of the conductor spaced apart. This facilitates the approach different crimping tools to the divergent To achieve compression.
In einer weiteren Ausführungsvariante sind die beiden Crimpverbindungen unmittelbar benachbart und daher besonders raumsparend anzuordnen. Die unterschiedliche Verpressung kann vorteilhaft gleichzeitig mit einem abgestuften Crimpwerkzeug hergestellt werden.In a further embodiment the two crimp connections are immediately adjacent and therefore to arrange particularly space-saving. The different compression can advantageously be produced simultaneously with a stepped crimping tool become.
Um ein Abscheren von Bestandteilen des Leiters durch den Crimpvorgang zu verhindern, kann insbesondere die stark verpresste Crimpverbindung in einem von 90° abweichenden Winkel hergestellt werden. Bei einem mit einer isolierenden Hülle ummantelten Leiter wird vorteilhaft eine weitere Crimpverbindung vorgesehen, die den Leiter auch noch in seinem isolierten Bereich umfasst.Around a shearing off of components of the conductor by the crimping process In particular, the heavily crimped crimp connection can be prevented in an angle other than 90 ° getting produced. In a case covered with an insulating sheath Head is advantageously provided a further crimp connection, which also includes the conductor in its isolated area.
Besonders vorteilhaft sind Kontaktteil und Anschlussteil einteilig ausgebildet, wodurch der Verbindungsvorgang mit dem Leiter vereinfacht wird.Especially Advantageously, contact part and connection part are integrally formed, whereby the connection process with the conductor is simplified.
In einer besonders vorteilhaften und kostengünstigen Ausführungsvariante sind das Kontaktteil und das Anschlussteil einstöckig ausgebildet und bestehen vorzugsweise aus einem Stanzstück.In a particularly advantageous and inexpensive embodiment the contact part and the connecting part are integrally formed and consist preferably from a stamped piece.
