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 tensile, 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 silk thread is stranded centrally when the individual wires are stranded.
  • the stranded conductors consist of approximately 30 to 60 individual conductors which are choked together.
  • the centrally inserted glass thread in particular increases the tensile strength of the strands without significantly increasing their cross-section, since it is embedded in the cavities (gusset) between the individual conductors when stranded.
  • an electrical line according to the preamble of claim 1 is known. It comprises insulation with a multi-wire metal conductor formed into a strand or a rope, and a tensile, fibrous support element formed centrally in the conductor from a bundle of carbon fiber filaments which are firmly connected to one another with a high-molecular, crosslinked resin.
  • the impregnation and firm connection with the high-molecular, cross-linked polymer resin reduce the elasticity of the support element and increase the breaking strength.
  • a reduction in the flexibility of the support element and thus the electrical line must be accepted.
  • the invention has for its object to provide an electrical line that withstands a small cross-section of an extreme tensile load, is easy to manufacture and process. 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) according to claim 1.
  • Advantageous embodiments of the invention are characterized in the further claims.
  • the carbon fiber can optimally distribute 0.007 millimeters in the inner gusset and fill all cavities. The highest tensile forces are absorbed if the bundle shows no rotation.
  • the carbon fiber filaments can be formed into a yarn with a twist of up to 20 d / m (twists per meter).
  • the bundle is treated with a size, e.g. B. on a polymer basis, which holds the individual filaments together, in particular glued together at their points of contact or lines. Such a size can already be applied by the manufacturer of the bundle.
  • 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, silicone, 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 the inner wires lie tightly around the bundle and that insulation is arranged around the wires.
  • other wire layers or other line components for. B. for reinforcement, shielding and the like.
  • the method steps according to claim 6 are provided for producing a filled line.
  • the bundle can be filled according to claim 7. 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.
  • 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
  • the cross-sectional area is 1.77 mm2.
  • the conductor cross-sectional area is 0.5 mm2, the tensile strength is approx. 130 Newtons.
  • 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 7,000th 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 (twists 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 approximately 0.2 mm, so that there is a conductor cross-sectional area of approximately 0.2 mm2. All cavities within the layer 14 of the wires 15 and between the individual filaments 13 of the bundle 11 are filled with a filler 16 based on petroleum jelly.
  • the layer 14 of the copper wires 12 is surrounded by insulation 17 made of polyvinyl chloride, which completely fills the outer gusset 18.
  • the diameter of the line 10 is 1.19 mm, its cross-sectional area 1.11 mm2.
  • the tear strength is 120 Newtons.
  • the new line therefore shows a reduction in diameter by 21% and in cross-sectional area by 38% with approximately the same tear strength. These are values that represent a significant advantage in special applications where space or weight savings are important.
  • the new line can be easily processed because the central carbon fiber does not interfere. Cutting, stripping, crimping, welding and soldering are still possible without any impairment, so that this cable 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 with a filling compound 16 in a stuffing device and coated. In the stranding device, the wires 15 are stranded around the centrally incoming bundle 11. The lay length is approx. 15 mm. The individual filaments 12 of the bundle 11 are radially compressed by the wires 15, so that all inner gussets or the entire space enclosed by the wires 15 is filled by the bundle 11, ie by the individual filaments 12 and the filler 16. The stranded structure produced is then passed through an extruder and coated with a plastic insulation 17, such as PVC, under radial pressure. The insulating material fills all outer gussets 18 without voids.
  • a plastic insulation 17 such as PVC
  • the exemplary embodiment described shows only a simple application of the invention.
  • the invention is also applicable to multi-core, round or flat cables that can serve a wide variety of purposes, e.g. B. for energy or message transmission, for control or measurement purposes.
