Definitions

  • the invention relates to an electrical line with insulation, with a multi-wire conductor made of metal formed into a strand or a rope and with a tension-resistant, fibrous element arranged centrally in the conductor.
  • DE-25 19 687-A 1 shows a method for producing a stranded conductor for electrical mains connection lines and the like, in which a thin thread of glass thread is stranded centrally when the individual wires are stranded.
  • the line conductors consist of approximately 30 to 60 individual conductors which are choked together.
  • the centrally inserted glass thread increases the tensile strength of the strands in particular without appreciably increasing their cross-section, since it is embedded in the cavities (gusset) between the individual conductors when stranded.
  • the invention has for its object to provide an electrical line that can withstand an extreme tensile load with a small cross section, is easy to manufacture and can be further processed. Furthermore, if desired, it should be able to be designed to be longitudinally watertight in a simple and permanent manner.
  • the fibrous element is formed from a bundle of carbon fiber filaments (carbon fibers).
  • Advantageous embodiments of the invention are characterized in the other claims. If the bundle is divided into at least 800, but depending on the design, also 1,000 to 12,000 individual filaments with a diameter of max.
  • the carbon fiber can optimally distribute 0.007 millimeters in the inner gusset and fill all cavities. The highest tensile forces are absorbed when the bundle shows no rotation.
  • the carbon fiber filament can be formed into a yarn with a twist of up to about 60 d / m (twists per meter).
  • the bundle can be treated with a size, e.g. B.
  • the conductor is constructed from an annular layer of at least 6 individual wires or the like, which surround the bundle with radial pressure, so that the inner gusset is completely filled with the individual filaments of the bundle. Additional wires or other line components can also be applied over the layer of individual wires. If the demands on the line are increased, the bundle can be filled with a liquid, pasty or powdery material. Such a filler greatly reduces the friction between the individual filaments and therefore has a positive effect on the flexibility of the line and on the durability of the filaments in the event of bending loads.
  • Fillers can be used, which also provide a longitudinal sealing of the line by forming a barrier to the liquid when water or any other liquid enters through swelling, foaming or another reaction.
  • Such fillers are based on petroleum jelly, petro jelly, silicones, cellulose and other materials.
  • a method for producing a line according to the invention provides that at least one layer of wires is stranded or stranded around a central bundle of carbon fiber filaments, that these wires lie tightly around the bundle and that insulation is arranged around the wires. Additional wire layers or other line components, e.g. B. for reinforcement, shielding and the like.
  • the method steps according to claim 9 are provided for producing a filled line.
  • the bundle can be filled according to claim 10. If further line elements are introduced, they would either have to be free of voids or should also be provided with an appropriate filling compound. It is recommended that the bundle is passed through a filling device immediately before the (first) layer of wires is applied, in which the bundle is soaked with the filler.
  • the invention creates an electrical line that can be made extremely thin or withstands extreme tensile loads. It can be produced economically, can be further processed without problems and can be designed to be longitudinally watertight and resistant to bending. Further advantages result from the example description below.
  • Figure 1 shows a conventional electrical line in cross section.
  • Figure 2 shows an electrical line according to the invention in cross section.
  • Figure 3 shows a section of the central, fibrous element with 3 individual filaments.
  • an electrical line 1 which consists of a stranded copper strand 2 with the structure 1 + 6 + 12 wires 3 with a diameter of 0.18 mm and an insulation 4 made of polyvinyl chloride.
  • the diameter of the line is 1.5 mm and its cross-sectional area is 1.77
  • FIG. 2 shows an electrical line 10, which consists of a central carbon fiber bundle 11 with a diameter of approximately 0.2 mm, which consists of approximately 1,000 individual filaments 12 with a diameter of approximately 7,000ths of a millimeter.
  • the individual filaments 12 have a size 13 based on polymer, which allows the individual filaments 12 to adhere to one another, and about 7 d / m (rotations per m).
  • the bundle 11 is surrounded by a layer 14 made of six copper wires 15.
  • the copper wires 15 have a diameter of about 0.2 mm, so that a conductor cross-section
  • the layer 14 of the copper wires 12 is insulated
  • Tear strength is 120 Newtons.
  • the new line accordingly shows a reduction in the diameter by 21% and the cross-sectional area by 38% with approximately the same tear strength. These are values which represent a significant advantage in special applications in which space or weight savings are important.
  • the new line can be processed without any problems since the central carbon fiber does not interfere. Cutting, stripping, crimping, welding and soldering are still possible without impairment, so that this line is particularly suitable for the production of all types of cable sets.
  • the six copper wires 15 and the carbon fiber bundle 11 are fed to a stranding device. Before the stranding point, the bundle 11 is filled and coated with a filling compound 16 in a stuffing device. In the stranding device, the wires 15 are stranded around the centrally entering bundle 11. The lay length is approx. 15 mm.
  • the individual filaments 12 of the bundle 11 are pressed together radially by the wires 15, so that all inner gussets or the entire space enclosed by the wires 15 are bundled by the bundle 11, ie by the individual filaments 12 and the filler 16 is filled out.
  • the resulting rope structure is then passed through an extruder and coated with plastic insulation 17 such as PVC under radial pressure.
  • the insulating material fills all outer gussets 18 without any cavities.
  • the exemplary embodiment described shows only a simple application of the invention.
  • the invention is also applicable to multi-core, round or flat cables which can serve a wide variety of purposes, e.g. B. for energy or message transmission, for control or measurement purposes.

Abstract

Pour permettre de réduire au minimum la surface de section ou le diamètre d'un conducteur électrique sollicitable en traction, il est proposé un élément central fibreux constitué d'un faisceau de fibres de carbone (11). Cette forme d'execution se réalise dans une version à étanchéité longitudinale à l'eau et se met en oeuvre sans problème par exemple sur des faisceaux de câbles.
