Definitions

  • the invention relates to an electrical line with at least two mutually insulated conductors, which are in a common inner jacket dimensionally accurate, cylindrical outer surface are embedded, in which over the Inner sheath an electrical screen formed as a braid and an outer one above Protective layer of insulating material are arranged (DE 298 08 657 U1).
  • Such lines are used, for example, for industrial machines and in the Automotive technology used for data or signal transmission. You should just be producible and robust and have the lowest possible weight. To disturbances to exclude such lines with an effective electrical shield be provided. After all, they should be as simple as possible for connection purposes to be stripped or stripped.
  • the known line according to DE 298 08 657 U1 mentioned at the beginning fulfills such Demands as far as possible. It consists of two with different colored insulation provided electrical wires, which lie side by side as a separating layer designated wrapping are surrounded. There is an extrusion over the separation layer produced inner jacket made of polyvinyl chloride. The inner jacket is made of a braid surrounded by tinned copper wires. An outer jacket is made of mechanical protection Polyvinyl chloride provided. The effort to manufacture this line is considerable. This applies in particular to the manufacture of the wire and separation layer Core. The interface must also be removed separately for contacting purposes become.
  • EP 0567 757 A discloses a cable in which the cable according to Art a star quad twisted lines in an inner jacket made of compressible Material, e.g. made of foamed plastic, are embedded.
  • the invention has for its object to the line described above design that it is easy to manufacture and easy to strip.
  • This line can be done in a single operation with the required Establish dimensional accuracy. Because the conductors respect an insulating distance are stranded with alternating lay direction, none will be in only one Direction rotating twisted baskets equipped with coils. The one because of his compressible design as an inner layer acting as a cushion layer compared to the stranding process of constant speed in a simple manner around the stranded conductors. This also applies to those in tandem then layers "screen” and "protective layer” to be applied. After one for The stripping is carried out without contacting Additional measures directly accessible, since the inner sheath directly after cutting can be removed from the conductors.
  • Fig. 1 is a schematic side view of the core of an electrical line L with two Shaped stranding elements E shown, which twisted together with changing direction of lay are. Such stranding is also referred to in the technical field as "SZ stranding".
  • SZ stranding In the course of line L changes at reversal points U, one of which is shown in FIG. 1 is shown, the direction of stranding for the stranding elements E.
  • Such lines are advantageously not rotating in only one direction Stranding devices required in conventional technology with one of the number of stranding elements corresponding number of coils must be equipped.
  • a line 1 according to the invention has the following structure, for example:
  • each of the wires 2 and 3 consists of an electrical conductor 4 and an insulation 5 surrounding the same.
  • the conductors 4 preferably consist of Copper. They can be solid as a wire or as a stranded conductor.
  • Insulation 5 is used in a preferred embodiment, foamed material. But it can also be solid.
  • the two wires 2 and 3 are with different colored insulation 5 provided. As insulation materials are for example polyethylene and polypropylene.
  • the cores 2 and 3 are made very dimensionally. They have their full length an exactly set outer diameter that is identical for both wires. After SZ stranding has the same one twice the outer diameter of the same corresponding height H.
  • the height H is dashed according to the diameter of the drawn circle K at each point of the line 1 - in the longitudinal direction seen - consistently present.
  • the Inner jacket 6 is made of insulating material shaped, which abuts the wires 2 and 3, fills the gusset between them and has a circular outer surface with a defined radius R.
  • the distance of the outer surface of the inner shell 6 of the circle K is constant all round.
  • the Inner jacket 6 consists of a mechanically stable but compressible material, for example made of foamed polyethylene, polypropylene or silicone. He can be shaped around the two wires 2 and 3 by means of an extruder.
  • the inner jacket 6 is made from one shown in FIG. 3
  • Band 7 made of foam material, preferably based on polyurethane, which longitudinally bent into a slotted tube 8 (FIG. 4) and thus around the two wires 2 and 3 is formed around:
  • the band 7 consists of a rectangular strip 9 of foam, which is on a Carrier film 10 is attached.
  • the carrier film 10 can on one side over the whole Extend the length of the band 7 to form a tab 11.
  • the band 7 is formed longitudinally into the slotted tube 8 in which its two side edges lie against one another at slot 12.
  • the tab 11 projects over the Slot 12 out. In the final state, it lies on the outside of the carrier film 10 and can also be used the same be glued.
  • the outer contour of the slotted tube 8 has over its entire length consistent dimensions with great accuracy.
  • the foam of the Strip 9 through the veins 2 and 3 z. T. considerably compressed. But he lies down without Gap formation also in the gusset between the two wires 2 and 3.
  • a shielding film 13 is located above the inner jacket 6 in the line 1 shown in FIG. 2 attached, the longitudinally running with overlapping edges around the inner jacket 6 is formed around. It can be glued to the same.
  • the screen film 13 is from one as a braid consisting of electrically well-conducting wires, electrical screen 14 surround. Copper wires can be used for the screen 14, which are also tinned could be.
  • An outer protective layer 15 is applied over the screen 14 and consists of a first film applied lengthways with overlapping edges and one around the same helical second overlap wrapped.
  • a sufficiently dense design of the braid for the screen 14 can on the Screen film 13 can be dispensed with.
  • a screen film 13 can for example an aluminum tape coated on one side with a hot melt adhesive be used.
  • the hot melt adhesive is activated by the application of heat, so that the Screen foil 13 glued to the inner jacket 6 and thereby further stabilized the same.
  • the two films of the protective layer 15 consist, for example, of one material Polyester. They are preferably effective on one side with heat becoming coated with adhesive. For example, materials are used as the adhesive Suitable for polymer base and hot melt adhesive.
  • the adhesive layer is on the first film outside and with the second film inside. When heat is supplied, the overlapping areas of the two foils and, on the other hand, the two foils glued together so that a firmly connected protective layer 15 results.
  • the line 1 according to FIG. 2 is of such dimensions with the structure described exactly that they are, for example, with a device described in DE 195 43 390 C1 can be stripped in a single operation.
  • the knife of the device penetrates the layers of line 1 up to circle K. After a rotation of 360 ° these layers and the rest of the inner jacket 6 can be removed from the wires 2 and 3 are subtracted.
  • the line 1 can be in addition to the embodiment of FIG. 2 in addition to FIG. 5 the two wires 2 and 3 additionally have strands 16 and 17 made of plastic, which in the gussets of the two wires 2 and 3 are arranged. They preferably consist of foamed material and in particular from highly foamed polyethylene or Polypropylene. The strands 16 and 17 are together with the wires 2 and 3 in the SZ process stranded.
  • the other structure of line 1 of FIG. 5 is the same as that line 1 according to FIG. 2.
  • bare conductors are used instead of the wires used, which can again be designed as wires or strands.
  • the diameter strands 24 and 25 are larger than conductors 22 and 23. They touch each other, so that the conductors 22 and 23 lying in their gussets with a sufficient distance are isolated from each other.
  • the strands 24 and 25 are very dimensionally accurate executed. They are both the same diameter. By their common height the diameter of the circle K is determined in this embodiment of the line 1.
