Problems solved by technology

[0005] Overall, however, such a twisting or stranding process is very costly, which results in higher costs, for example, compared with a core wire with a solid wire instead of a stranded conductor

Embodiment Construction

[0038] exemplarily described below and in figure 1 The line 2 of the single-core wire shown in the not-to-scale cross-sectional view is formed by the core wire 4 .

[0039] The line here comprises a wire harness 6 which is sheathed by an insulating sheath 8 made of plastic. In the exemplary embodiment, each strand 6 here consists of seven individual wires 10 with a diameter d1<1 mm, wherein six individual wires 10 rest on the central individual wire 10 at the periphery.

[0040] as in figure 1 As shown in , the wire harness 6 is embodied as a compressed wire harness 6 , and the individual wires 10 are correspondingly pressed against one another. Therefore, the thickness of each wire bundle 6 or the diameter of each wire bundle 6 is reduced, and the cross-sectional shape of each single wire 10 also deviates from a circular shape due to the deformation each single wire 10 undergoes during the pressing of the wire bundle 6 . The overall diameter d2 of the harness 6 is, for exa...

Abstract

The invention relates to a cable (2) and a method for producing a corresponding cable (2), the cable having a bundle (6) of individual wires (10) and an insulating sheath (8), Therein, the strand (6) is guided in the delivery region along a central longitudinal axis (20) through a shaping element (18) directly before the extruder (16) in order to predetermine and guide the cross-sectional shape of the strand , wherein the shaping element (18) is rotated around the central longitudinal axis (20), and wherein the insulating sheath (8) is subsequently applied to the wire harness (6) by means of the extruder (16).

Description

technical field [0001] The invention relates to a method for producing an electrical circuit having at least one core wire with a bundle of individual wires and an insulating sheath surrounding the bundle. The invention also relates to such an electrical line and to a motor vehicle electrical system having a corresponding electrical line. Background technique [0002] Such a method and such an electrical circuit are known, for example, from US 4,471,161. This document describes stranded wires and their production, in which a plurality of individual wires are twisted together to form a stranded wire by means of a twisting machine. The litz wires produced in this way are also sheathed with a sheath extruded onto them to form the core. Such core wires with stranded conductors are used in particular in applications where a high degree of flexibility of the line is desired. This flexibility is due to the fact that stranded conductors have multiple individual wires compared to ...
