Definitions

  • the invention relates to a flexible electrical line according to claim 1.
  • Such flexible electrical lines are used for example as elevator lines or as so-called drag chain line.
  • the cables are constantly moved, especially in drag chains.
  • the cables are either shielded or unshielded, whereby the shielded version is used if special requirements for electromagnetic compatibility are made.
  • a practiced solution for extreme demands consists in a flat cable construction with laterally arranged steel cables. Such a conduit requires an increased space requirement.
  • Another solution consists in a conventional round construction of the line, wherein the jacket consists of a so-called steel / polyurethane composite construction.
  • the disadvantages of this line consist in a poor connection of the support element to the drag chain and in a difficult assembly.
  • From the DE-C-42 18 707 is a flexible cable for power supply of cutting machines known, which consists of a stranding of three arranged around a central element energy core. The stranding between the energy wires are filled with jute tears. The stranded bandage designed in this way is enclosed by an inner jacket. The inner casing is surrounded by a braided steel braid and an outer jacket made of polychloroprene.
  • the cable for use in operating rooms which has a reinforcement intended to protect the sheath against attack by sharp surgical equipment.
  • the cable consists of a cable core of electrically insulated conductors and a shield surrounding the conductors made of a metallic wire mesh.
  • the cable core is surrounded by an inner sheath, an applied on the inner sheath reinforcement of metal wires and an outer sheath.
  • the outer jacket penetrates the spaces between the metal wires and is connected to the inner jacket.
  • the coverage of the reinforcement is up to 50%.
  • the present invention has set itself the task of providing a flexible electrical cable for extreme loads, for travel distances of over 30 meters with speeds up to 500 m / min and accelerations or
  • each wire bundle is stranded, each consisting of three wires 8, 9 and 10.
  • Each wire consists of a conductor 11, z. B. a stranded conductor and insulation 12 z. B. from a two-layer insulation, as described in the earlier German patent application 100 36 610.4 dated 27. 07. 2000 is described.
  • thermoplastic polyurethane which fills the gusset between the wire bundles.
  • central element 1- in some cases, however, in addition to this - can be provided in the gussets not shown tensile and compression stable elements.
  • the inner jacket 13 is surrounded by a winding 14, which preferably consists of a nonwoven ribbon.
  • a Arm michsgeflecht 15 which is applied with an optical coverage of 30 - 80%, so that the material of the outer shell 16 can penetrate the Arm michsgeflecht 15 and penetrate to the winding 14.
  • Outer jacket 16 and reinforcement mesh 15 form a unit that can be easily lifted off the inner jacket 13 and the winding 14 in the assembly of the cable ends.
  • the reinforcing braiding 15 forming elements 17 are preferably flat elements that are extremely flexible, yet tensile and stably stable.
  • a flat element 17 consists of four juxtaposed elongated objects 18, which are jointly surrounded by a plastic sheath 19, preferably made of polyamide.
  • the objects 18 are either folded steel wires or flat polyamide (Kevlar), glass or carbon fiber fibers or fiber bundles running in a matrix of polyamide.
  • the outer jacket 16 is made with particular advantage of thermoplastic polyurethane by extrusion.
