Problems solved by technology

This prevents cold welding of the intervening individual wires from occurring, thereby reducing not only the reliability of the mechanical connection of the contact part to the strand, but also the electrical conductivity of the connection

Embodiment Construction

[0021] Preferred embodiments are explained in the following description. But of course, the invention can also be applied to other cables, with stranded conductors made of other materials and for other contact parts. It is also conceivable to connect the contact part not integrally with the support or the pin as described below, but alternatively also with the sleeve or with both parts. It is also possible for the connection to be formed not in one piece, but eg in a material fit, force fit and / or form fit.

[0022] exist figure 1A cable 1 is shown in simplified form in the middle. In the illustrated embodiment the cable 1 is a round conductor with a substantially circular cross-section. The cable 1 has a litz conductor 4, which consists of a plurality of individual wires. The litz conductor 4 can be formed twisted differently from the illustration or, as shown, can be formed from wires running parallel to one another. Furthermore, the cable includes insulation 5 in the u...

Abstract

A method is provided for prefabricating a cable. The method involves introducing an elongate, pin-shaped abutment at the end of a cable between exposed individual wires of a litz-wire conductor of the cable, positioning a sleeve around the outer circumference of the exposed litz-wire conductor, such that the sleeve surrounds at least one partial length of the exposed litz-wire conductor and of the abutment, and compressing the sleeve so that a contact part, which is connected to the sleeve and / or the abutment, is electrically connected to the litz-wire conductor. A cable prefabricated with this method is also provided.

Description

technical field [0001] The present invention relates to prefabricated cables. The invention relates in particular to a cut-in cable comprising light metal strands, for example aluminum strands. However, the invention can also be transferred to other strand materials, for example magnesium and copper strands or strands made of alloys of one or more of the abovementioned or other suitable materials. Such cables are mainly used in automobiles to supply electrical consumers with electrical energy. This cable is also used for grounding of electrical systems. Besides the method of prefabricating cables, the invention also relates to prefabricated cables. Background technique [0002] There has long been a desire, mainly in the automotive sector, to produce cables from light metals, such as magnesium or aluminum and alloys thereof, in order to reduce weight and replace expensive materials with cost-effective alternatives. When these cables are electrically connected to the cont...
