Problems solved by technology

[0006] Furthermore, when using aluminum cables, electrical taps are always at risk of an increased transition resistance due to oxidation of the aluminum conductor and electrical power loss at this transition resistance leading to undesired heating of the conductors

Embodiment Construction

[0053] Figure 1a An electrical cable 2 with metallic stranded conductors 4 and insulation 6 is shown.

[0054] The metal conductor 4 is preferably a stranded conductor and is especially resistant to bending. The conductor 4 is preferably a round conductor. The material of the litz wires of the conductor 4 is preferably aluminum, in particular aluminum 99.5. The bending resistance of the cable 2 is obtained if the cable 2 does not undergo plastic deformation due to its own weight. A force greater than gravity is required to cause plastic deformation of the cable 2 .

[0055] The insulation 6 preferably consists of PVC or silicone.

[0056] Such as Figure 1b As shown, the cable 2 is stripped of its insulation in an intermediate region, ie away from its respective distal ends, to form a stripped region 8 . In the stripped region 8 the conductor 4 is free of the insulation 6 .

[0057] After the stripped region 8 has been produced, the cable 2 or its conductor 4 can be den...

Abstract

The invention relates to a method for establishing a connection between an electric connection element for a motor vehicle electrical system and a cable of the motor vehicle electrical system, in which method: the cable (2) is provided with a metal stranded conductor (4); then the metal stranded conductor is mechanically compressed such that a planar region is formed, an integral connection beingformed between strands of the stranded conductor (4) during said compression; and subsequently the connection element is integrally bonded to the planar region.

Description

technical field [0001] The invention relates to a method for establishing a connection between an electrical connection element for an on-board electrical system of a motor vehicle and a cable of an on-board electrical system of a motor vehicle. The invention also relates to a cable and the use of the cable. Background technique [0002] In the on-board electrical system of a motor vehicle, the electrical output to the load needs to be carried out from the main energy line which is directly connected to the positive pole of the battery. Due to the large number of electrical loads to be connected into the on-board power system, extensive branching of the on-board power system lines is required. Some loads require high power from the battery and must therefore be connected to the distribution network via cables with large conductor cross-sections. Usually several groups of loads have to be protected by means of a common fuse, and on the other hand it is also necessary to pro...
