Definitions

  • the invention relates to a flexible electrical line with at least two electrical wires, each of which has a stranded conductor surrounded by an insulation and which are combined in a soul, which is surrounded by a protective cover ( DE 100 36 610 A1 ).
  • Such flexible lines can be used for example as connecting lines between portable consumers and a voltage or signal source. They then serve, for example, as connecting lines for cranes, machine tools and robots.
  • the lines can also be used in medical technology or as connecting lines in motor vehicles. They should be able to withstand high mechanical loads in all possible applications and remain flexible over a wide temperature range, for example between -90 ° C and + 200 ° C.
  • the well-known line after the above-mentioned DE 100 36 610 A1 is intended for use in drag chains.
  • the insulation of the wires is designed in two layers.
  • the two layers are made of different materials based on polypropylene.
  • the two stranded cores are surrounded by a gusset between them filling inner sheath.
  • an outer jacket made of a high-quality insulating material is arranged. It consists for example of a thermoplastic elastomer.
  • the invention has for its object to make the line described above so that it can be used in a wide temperature range, has a high mechanical strength, is resistant to abrasion and can be manufactured inexpensively.
  • the protective cover has a soul surrounding layer of unsintered polytetrafluoroethylene, over which a same tightly enclosing braid of high-strength and abrasion-resistant threads is attached with an optical coverage of at least 90%.
  • the protective cover of this line consists essentially of unsintered polytetrafluoroethylene (PTFE).
  • PTFE polytetrafluoroethylene
  • This PTFE layer is almost completely surrounded by a likewise belonging to the protective cover high-strength and abrasion-resistant braid.
  • the PTFE can be used under all conceivable environmental conditions, since this material is resistant to all known materials, in a wide temperature range, for example, from -90 ° C to + 200 ° C.
  • the line is highly flexible in spite of the material "PTFE", which in itself is known to be stiff, since the layer surrounding the core consists of unsintered and therefore still relatively soft PTFE.
  • the high-strength and abrasion-resistant threads of the braid can very tightly enclose the PTFE layer, whereby the threads can press into the layer and are then virtually embedded in the PTFE.
  • the line is also protected by the braid as a whole against mechanical stress, especially against abrasion.
  • the line according to Fig. 1 has three stranded cores 1, 2 and 3, each of which has an electrical conductor 5 surrounded by an insulation 4.
  • the gaps (gusset) between the wires 1, 2 and 3 are filled with existing existing insulating filler 6 so that a total of a soul 7 results in at least approximately circular cross-section.
  • the core 7 is surrounded by a protective covering which consists of a layer 8 of unsintered PTFE and a mesh 9 surrounding it.
  • a thin protective layer 10 may be applied over the mesh 9.
  • the cable should have at least two wires that can be stranded together.
  • the wires can also be mounted parallel to one another in the core 7 and, for example, be connected to one another in the form of a flat cable in a common casing.
  • the conductors 5 of the wires 1, 2 and 3 are designed as flexible stranded conductors whose individual wires can be made of copper. As individual wires but also surrounded by a copper layer steel wires can be used. The individual wires may be arranged around a high-strength core wire 11, which consists for example of a chromium / nickel steel. A stranded conductor formed in this way can be silver-plated or nickel-plated.
  • the insulation 4 of the wires 1, 2 and 3 may consist of a temperature-resistant insulating material, such as ethylene tetrafluoroethylene (ETFE), fluorinated ethylene propylene (FEP), PTFE or polyfluoroalkoxy (PFA).
  • ETFE ethylene tetrafluoroethylene
  • FEP fluorinated ethylene propylene
  • PFA polyfluoroalkoxy
  • the filling material 6 may be, for example, a material based on silicone and applied by extrusion. In the interstices between the wires 1, 2 and 3 but also existing PTFE filling yarn can be arranged.
  • the layer 8 is advantageously made of at least one ribbon-shaped sheet of unsintered PTFE, which is wrapped in an overlapping manner around the core 7, preferably with an overlap of about 50%.
  • two or more films for the layer 8.
  • the two films 12 and 13 may be wound in accordance with Fig. 2 with the same sense of winding.
  • the overlapping areas of the lower film 12 are expediently covered by the overlying film 13 so that the overlapping areas of both films are shifted in the axial direction against each other.
  • the two films 12 and 13 can also be wound up with opposite winding sense. For example, they have a thickness lying between 25 ⁇ m and 200 ⁇ m. Their width can be between 1.5 mm and 5.0 mm. But they can also be much wider, for example, with large diameters, for example, up to 80 mm.
  • the braid 9 made of high-strength threads is applied under firm contact with the layer 8 of unsintered PTFE, preferably so that the threads penetrate at least slightly into the outer film 13 of the layer 8.
  • the mesh 9 is designed so tight that results in an optical coverage of the layer 8 of at least 90%.
  • the optical coverage is advantageously 93% to 95%.
  • the threads of the braid 9 consist for example of an aramid yarn, which is surrounded by a shell of high temperature resistant material, in particular PEEK (polyetheretherketone).
  • aramid yarn a steel wire or a carbon fiber yarn may be used.
  • the diameter of aramid yarn can be between 0.1 mm and 0.3 mm.
  • the shell may have a wall thickness of 50 microns.
  • the threads of the braid 9 are expediently applied to the layer 8 with a very short pitch, which corresponds to a braiding angle lying between 35 ° and 65 ° to the line axis.
  • the braiding angle is advantageously 54 °.
  • a so-called nano-coating material based on PTFE can be applied as a very thin protective layer 10.
  • its thickness may be between 50 nm and 30 ⁇ m, preferably 20 ⁇ m. It can serve the additional sealing and also offers the possibility of a color coding of the line. It may be colorless or colored, preferably black.
  • Layer 8, braid 9 and protective layer 10 are resistant to almost all organic and synthetically produced media, such as oils, acids, alkalis, cold cleaners.
  • the additional protective layer 10 can also be designed to be water-repellent.
  • the individual elements and layers of the line according to FIGS. 3 and 4 are constructed analogously to the line according to FIGS. 1 and 2.
  • the line according to FIG. 3 has four cores 14, 15, 16 and 17 with a stranded conductor 5, which are wound around a tensile core element 18.
  • This line, including the filling material 6 has an at least approximately circular core 7, over which the layer 8, the braid 9 and optionally the protective layer 10 are attached.
  • the above-described structure of the line applies in principle to the line of FIG. 4. It has three wires 19, 20 and 21, each of which is surrounded by an electric screen 22.
  • the screen 22 may for example consist of an overlapped wound, plastic-laminated metal foil with the metal layer outside or from a copper wire umseilung with a surface coverage of at least 90%, optimally 95% exist.
  • the shielded wires 19, 20 and 21 are in the stranded state in contact with each other.
  • For secure electrical connection can be arranged in at least one of the gusset between the wires a copper wire 23, which rests against the two shields 22 of the adjacent wires.
  • a winding of a semiconductive plastic film may be applied. It can consist of a semiconducting, overlap-wound PTFE film.
  • an insulating layer 24 is arranged, which consists either of a multilayer winding of plastic films, for. As sintered and or unsintered PTFE films, or from an extruded layer, for. B. silicone, may exist.
  • the insulating layer 24 ensures a defined dielectric strength between the shields 22 of the wires 19, 20 and 21 and an overall shield 25 which is mounted over the insulating layer 24.
  • the overall shield 25 can be made, for example, as a copper wire mesh with an optical coverage of at least 85%, optimally 90%, be executed.
  • the protective layer consisting of the layer 8 and the mesh 9 is arranged. Again, the additional protective layer 10 may be appropriate.
  • the line according to the invention can be used in particular in the embodiment of FIG. 4, for example as a high-temperature safety line for hybrid drives of motor vehicles, z. B. as Hochwoodsmotor- or generator line or in 2-wire flat form as high voltage battery line.
  • the wire shields in the cable can be used for protective conductor systems or for special sensor systems with an applied low-voltage auxiliary voltage. In case of violation of the line, z. B. in a puncture, a short circuit between the screens of the line leads to a safe shutdown.
  • the single core shielding ensures that every phase of the cable is safely protected.
