- the invention further relates to a method for producing a connection of an electric cable having the features of the preamble of claim 8.
- a connection of an electrical cable to a contact part is known in which an insulation of the cable is removed in an end region of the cable and a sleeve made of aluminum or an aluminum alloy is inserted over the stripped part of the cable and pressed with the cable. Through the open end of the sleeve through the contact part is welded to the cable.
- connection of power supply lines in particular those made of aluminum or aluminum alloys, which are increasingly preferred because of their price and weight, especially in the automotive compared to those made of copper or copper alloys, with contact parts made of copper or copper alloys, a resistance without resistance, mechanically strong and corrosion - free or . corrosion-resistant compound.
- the contact part is welded to the cable through the end wall, the welded connection between the cable and the contact part is completely sealed from the environment and thus protected against particularly saline liquids, which corrosion between parts with different electrochemical potential, in the present case the cable made of aluminum or an aluminum alloy and the contact part of copper or a copper alloy, promote.
- the close calibration of the contact part through the bottom of the aluminum can also increases or ensures the lateral tensile strength of the contact part at a high or even level.
- the drawings show an embodiment of a contact part 1 according to the invention, which is to be connected to a cable 2.
- the contact part 1 may, for example, as in the AT 510 475 A described Kontäktteil be executed and consists essentially of a first portion 4 and a second portion 5, which is arranged approximately at right angles to the first portion 4.
- the first section 4 has an opening 6 through which a screw, not shown, can be inserted in order to connect the contact part according to the invention with another electrical component, for example with a vehicle battery.
- the second section 5 serves to connect the contact part 1 to the cable 2, the electrical conductor 7 is either solid or may have a plurality of electrical wires or strands 7.
- the electrical conductor 7 is surrounded in a known manner by an insulation 8, which ends at a certain distance from the end 9 of the electrical conductor 7.
- the end 9 of the electrical conductor 7 is surrounded by a connecting cap 10, which has a sleeve 11 and an end wall 12.
- the sleeve 11 is in a region 13 which is spaced from the end 9 and the end face of the conductor 7, with this mechanically compressed.
- the conductor 7 located under the rear portion 13 is pressed together more strongly than that under the front portion of the sleeve 11 lying portion of the conductor 7, whereby the conductor 7 is supported from the rear, while the contact part 1 is pressed during welding against the end wall 12 and subsequently against the conductor 7 and penetrates into this, as will be explained in more detail below ,
- connection cap 10 and the electrical conductor 7 are made of aluminum or an aluminum alloy.
- the contact part 1 is made of copper or a copper alloy and may optionally be coated with a nickel layer.
- the second section 5 of the contact part 1 has a projection 14 with a contact surface or end face 15 with a three-dimensional shape, which is increased in a central region with respect to an edge region surrounding the middle region.
- the end face 15 has in the illustrated embodiment, approximately the shape of a spherical cap with a constant radius of curvature. It is within the scope of the invention, however, also possible to use other surfaces in which, for example, the radius of curvature in the central region is greater than in the edge region or vice versa, as would be the case for example with a segment of an ellipsoid of revolution. Also, a substantially conical end face 15 would be conceivable, for example.
- the contact part 1, in particular the central region of the projection 14, has a projecting region, since then, at the first contact with the end wall 12, well-defined conditions exist spatially and with respect to the resistance at the start of the welding process, which results in a reduced scattering of the Results in the series process.

At the same time, the contact part 1 and the connection cap 10 are pressed against each other.
- the end wall 12 begins to melt in the contact region with the end wall 15 of the contact part 1, the contact part 1 itself but not, so that the projection 14 through the end wall 12 by and subsequently also melts into the conductor 7, when these parts are pressed further and further together.
- the wall thickness of the end wall 12 is preferably slightly smaller than the wall thickness of the sleeve 11 so that it can be easily melted through during the welding process, but the sleeve 11 is sufficiently stable or remains.
- the melt of the conductor 7 begins to flow towards the edge region and fills the free space between the connecting cap 10 and the conductor 7, since the end wall 12 prevents melt flows out to a significant extent to the outside.
- the conductor 7 is preferably a stranded cable, the melt can also flow between the strands and spread there, so that a total of a very large-scale, compact and strong welded joint between the contact part 1 and the conductor 7 and the connecting cap 10 is formed, so that the weld also has only a low electrical resistance and is protected against corrosion.

Bei der Verbindung von Energieversorgungsleitungen, insbesondere solchen aus Aluminium oder Aluminiumlegierungen, die auf Grund ihres Preises und Gewichtes insbesondere im Automobilbau zunehmend gegenüber solchen aus Kupfer oder Kupferlegierungen bevorzugt werden, mit Kontaktteilen aus Kupfer oder Kupferlegierungen, soll eine möglichst widerstandslose, mechanisch feste und korrosionsfreie bzw. korrosionsgeschützte Verbindung hergestellt werden.In the connection of power supply lines, in particular those made of aluminum or aluminum alloys, which are increasingly preferred because of their price and weight, especially in the automotive compared to those made of copper or copper alloys, with contact parts made of copper or copper alloys, a resistance without resistance, mechanically strong and corrosion - free or . corrosion-resistant compound.
Erfindungsgemäß wird zur Lösung dieser Aufgabe bei einer Verbindung der eingangs genannten Art vorgeschlagen, dass der Kontaktteil durch die Stirnwand hindurch mit dem Leiter verschweißt ist.According to the invention is proposed to solve this problem in a compound of the type mentioned that the contact part is welded through the end wall to the conductor.
Erfindungsgemäß wird zur Lösung dieser Aufgabe bei einem Verfahren der eingangs genannten Art vorgeschlagen, dass der Kontaktteil durch die Stirnwand hindurch mit dem Leiter verschweißt wird.According to the invention is proposed to solve this problem in a method of the type mentioned that the contact part is welded through the end wall with the conductor.
Da der Kontaktteil durch die Stirnwand hindurch mit dem Kabel verschweißt wird, ist die Schweißverbindung zwischen Kabel und Kontaktteil gegenüber der Umgebung vollständig abgeschlossen und somit vor insbesondere salzhaltigen Flüssigkeiten geschützt, welche Korrosion zwischen Teilen mit unterschiedlichem elektrochemischen Potential, im vorliegenden Fall dem Kabel aus Aluminium oder einer Aluminiumlegierung und dem Kontaktteil aus Kupfer oder einer Kupferlegierung, fördern.Since the contact part is welded to the cable through the end wall, the welded connection between the cable and the contact part is completely sealed from the environment and thus protected against particularly saline liquids, which corrosion between parts with different electrochemical potential, in the present case the cable made of aluminum or an aluminum alloy and the contact part of copper or a copper alloy, promote.
Die enge Kalibrierung des Kontaktteils durch den Boden der Aluminiumdose erhöht bzw. sichert außerdem die Seitenzugfestigkeit des Kontaktteils auf hohem bzw. gleichmäßigem Niveau.The close calibration of the contact part through the bottom of the aluminum can also increases or ensures the lateral tensile strength of the contact part at a high or even level.

Die Zeichnungen zeigen eine Ausführungsform eines erfindungsgemäßen Kontaktteiles 1, der mit einem Kabel 2 zu verbinden ist. Der Kontaktteil 1 kann z.B. wie der in der
Der zweite Abschnitt 5 dient zur Verbindung des Kontaktteiles 1 mit dem Kabel 2, dessen elektrischer Leiter 7 entweder massiv ist oder mehrere elektrische Drähte oder Litzen 7 aufweisen kann. Der elektrische Leiter 7 ist auf an sich bekannte Weise von einer Isolierung 8 umgeben, die in einem gewissen Abstand vor dem Ende 9 des elektrischen Leiters 7 endet.The
Im Bereich ohne Isolierung 8 ist das Ende 9 des elektrischen Leiters 7 von einer Verbindungskappe 10 umgeben, die eine Hülse 11 und eine Stirnwand 12 aufweist. Die Hülse 11 ist in einem Bereich 13, der vom Ende 9 bzw. der Stirnfläche des Leiters 7 beabstandet ist, mit diesem mechanisch verpresst. Dadurch wird der unter dem hinteren Abschnitt 13 liegende Leiter 7 stärker zusammen gepresst als der unter dem vorderen Abschnitt der Hülse 11 liegende Bereich des Leiters 7, wodurch der Leiter 7 von hinten gestützt wird, während der Kontaktteil 1 beim Schweißen gegen die Stirnwand 12 und in weiterer Folge gegen den Leiter 7 gedrückt wird und in diese eindringt, wie in der Folge noch näher erläutert werden wird.In the area without
Die Verbindungskappe 10 und der elektrische Leiter 7 bestehen aus Aluminium oder einer Aluminiumlegierung. Der Kontaktteil 1 besteht aus Kupfer oder einer Kupferlegierung und kann gegebenenfalls mit einer Nickelschicht überzogen sein.The
Der zweite Abschnitt 5 des Kontaktteils 1 weist einen Vorsprung 14 mit einer Kontaktfläche bzw. Stirnfläche 15 mit einer dreidimensionalen Form auf, die in einem Mittelbereich gegenüber einem den Mittelbereich umgebenden Randbereich erhöht ist. Die Stirnfläche 15 weist im dargestellten Ausführungsbeispiel etwa die Form einer Kugelkalotte mit konstantem Krümmungsradius auf. Es ist im Rahmen der Erfindung aber auch möglich, andere -Flächen zu verwenden, bei denen beispielsweise der Krümmungsradius im Mittelbereich größer als im Randbereich ist oder umgekehrt, wie dies beispielsweise bei einem Segment eines Rotationsellipsoids der Fall wäre. Auch eine im Wesentlichen kegelförmige Stirnfläche 15 wäre beispielsweise denkbar. Von Vorteil ist jedenfalls, wenn der Kontaktteil 1, insbesondere der Mittelbereich des Vorsprunges 14, einen vorspringenden Bereich aufweist, da dann beim ersten Kontakt mit der Stirnwand 12 räumlich und hinsichtlich des Widerstandes bei Start des Schweißprozesses gut definierte Verhältnisse vorliegen, die eine reduzierte Streuung der Ergebnisse im Serienprozess ergeben. An die Stirnfläche 15 schließt ein Abschnitt mit einer zylindrischen Außenfläche 16 an und an diesen wiederum ein Flansch 17.The
Die Verbindung des erfindungsgemäßen Kontaktteiles 1 mit dem elektrischen Leiter 7 des Kabels 2 erfolgt z.B. so, dass zunächst der Mittelbereich 15 an die Stirnwand 12 der Verbindungskappe 10 angelegt und an den Kontaktteil 1 und die Verbindungskappe 10 eine elektrische Spannung angelegt wird, um den Kontaktteil 1 und den Leiter 7 mit der Verbindungskappe 10 durch ein Widerstandsschweißverfahren miteinander zu verschweißen. Gleichzeitig werden der Kontaktteil 1 und die Verbindungskappe 10 gegeneinander gedrückt.The connection of the
Da das Aluminium oder die Aluminiumlegierung einen geringeren Schmelzpunkt aufweist als das Kupfer oder die Kupferlegierung, beginnt die Stirnwand 12 im Kontaktbereich mit der Stirnwand 15 des Kontaktteils 1 zu schmelzen, der Kontaktteil 1 selbst aber nicht, so dass der Vorsprung 14 durch die Stirnwand 12 durch und in weiterer Folge auch in den Leiter 7 hinein schmilzt, wenn diese Teile immer weiter zusammen gedrückt werden. Die Wandstärke der Stirnwand 12 ist bevorzugt etwas kleiner als die Wandstärke der Hülse 11, damit sie beim Schweißprozess leichter durchschmolzen werden kann, die Hülse 11 aber ausreichen stabil ist bzw. bleibt.Since the aluminum or the aluminum alloy has a lower melting point than the copper or the copper alloy, the
Da der Mittelbereich gegenüber dem Randbereich der Stirnfläche 15 vorsteht, beginnt die Schmelze des Leiters 7 zum Randbereich hin abzufließen und füllt den freien Raum zwischen der Verbindungskappe 10 und dem Leiter 7, da die Stirnwand 12 verhindert, dass Schmelze in nennenswertem Ausmaß nach außen abfließt. Da der Leiter 7 bevorzugt ein Litzenkabel ist, kann die Schmelze auch zwischen die Litzen fließen und sich dort verteilen, sodass insgesamt eine äußerst großräumige, kompakte und feste Schweißverbindung zwischen dem Kontaktteil 1 und dem Leiter 7 und auch der Verbindungskappe 10 entsteht, sodass die Schweißverbindung auch nur einen geringen elektrischen Widerstand aufweist und gegen Korrosion geschützt ist.Since the central region protrudes from the edge region of the
