Definitions

  • a flexible electrical conductor which consists of a tensile non-metallic element (1) and a plurality of metallic wires (2) extending helically around the element (1), the diameter of the metallic wires (2) being many times smaller as the diameter of the element (1), and the surface of the element (1) is only partially covered by the metallic wires (2).
  • the invention relates to a flexible electrical conductor according to the preamble of claim 1.
  • a flexible electrical line having at least one electrical conductor.
  • the conductor consists of a tensile non-metallic element and a plurality of arranged around the element metallic wires of good electrical conductivity material.
  • the tensile element consists of a loose composite of a plurality of aramid threads whose cross section corresponds to the cross section of the individual wire.
  • the conductor is surrounded by electrical insulation.
  • the flexible cable described is preferably used in motor vehicles. It must therefore be well bendable and tensile strength and must also be able to withstand high mechanical loads even at elevated temperatures.
  • the EP 1 089 299 shows a tensile cable in which a plurality of wires are made of a good electrically conductive material around a central element herumversilt.
  • the central element consists of several stranded threads of a tensile material embedded in a metallic matrix.
  • a common insulating layer is applied over the layer of electrically conductive wires.
  • the present invention has for its object to improve the above-mentioned lines to the effect that the bending resistance is significantly improved.
  • the cross section of the central element is many times greater than the cross section of the individual metallic wires.
  • the cross-section of the conductor be asymmetric, i. H. is a one-sided "open" design and by appropriate selection of lay length, wire diameter and wire number, the surface of the central element is only partially covered by the metallic wires. Due to the relatively large diameter of the central element, the metallic wires experience a lower bending load at the same bend than in the lines according to the prior art. Due to the one-sided "open" cross-section, the metallic wires can slip on the upsetting side, whereby a crushing and thus damage to the metallic wires is prevented.
  • 1 denotes a central element consisting of a plurality of monofilaments 1a.
  • the monofilaments 1a are made of a plastic with a high tensile strength. Monofilaments 1a of aramid or polyester are preferred.
  • On this central element 1 a plurality of metal wires 2 is stranded. The metal wires 2 are combined to form a group 2a. The diameter of the metal wires 2 and the lay length of the group 2a are selected so that a space 3 remains between two adjacent turns of the group 2a.
  • metal wires for example, copper, aluminum or their alloys but also steel can be used depending on the application.
  • wires 2 made of copper-plated steel wire Such wires consist of a steel core 2b, which is covered with a thin copper layer 2c.
  • the individual metal wires 2 can slide freely on the surface of the central element 1 without appreciable impairment, so that in the case of a bending stress, the metal wires 2 on the upsetting side can move in the direction of the free space 3.
  • a conductor made with copper-clad, work-hardened steel wires made according to the teachings of the invention had the following dimensions: Diameter of the central element 1 0.54 mm Diameter of the metal wires 0.06 mm Number of metal wires 21 Lay length of the metal wires 3.4 mm Distance between two turns 0.8 mm
