Abstract (en)

The connection (V) uses a friction welding method for connecting the end of an Al cable (1) with individual filament wires (2) to a Cu cable termination (4) enclosing the latter, e.g. a battery terminal clamp (5), with the friction heat between the 2 materials used for melting the latter so that they are welded together. An Independent claim for a cable termination connection method is also included.

Abstract (de)

Eine Verbindung (V) des elektrischen Aluminiumkabels (1) mit einem Anschlußstück (4) aus anderem Metall, insbesondere Kupfer oder einer Kupferlegierung, wird durch Zusammendrücken der das Aluminiumkabel (1) bildenden Drähte (2) im Endbereich und Verschweißen mit dem Anschlußteil (4), insbesondere durch ein Reibschweißverfahren, bewirkt. Dabei wird die Reibwärme zwischen den Materialien genutzt, um beide Materialien zu schmelzen und ohne Zusatzschweißstoff miteinander zu verbinden. Das Aluminiumkabel (1) wird dazu mit einer mit ihm verpreßten Stützhülse (13) versehen, die die einzelnen Drähte (2) an der Verbindungsstelle praktisch zu einer vollen Fläche macht und selbst mit dem Anschlußteil (4) mitverschweißt wird. Somit können Anschlußteile aus Kupfer dicht und elektrisch gut leitend verbunden werden, ohne daß im Verbindungsbereich eine Korrosionsgefahr aufgrund unterschiedlich edler oder unedler Metalle besteht. <IMAGE>
