Definitions

  • the invention relates to a method for producing a flexible wiring harness, in particular a wiring harness for a motor vehicle.
  • Cable strands with a predetermined tree-like structure - known as harnesses - are formed from a composite of several electrical lines and serve the electrical connection of components, consumers and assemblies.
  • the electrical lines are combined in parallel with predetermined cable outlets and preferably fixed by a winding tape or summarized by an insulating tube.
  • the wiring harness must be flexible and should be windable so that it is packageable and easier to transport and should and can be angled for installation and installation in the vehicle by 90 °. As the number of consumers and control units in modern motor vehicles increases, so does the number and possibly also the cross-section of the lines to be connected in such a wiring harness, thus reducing its flexibility.
  • the wiring harness is getting stiffer.
  • a longitudinally watertight electrical cable with a cable core constructed of plastic insulated wires and a jacket surrounding the core.
  • the cable core is filled over the entire cable length with a water-repellent substance, such as petroleum jelly or Petrolat and over the entire length of the cable core are arranged one or more elastically compressible elements, whereby the occurring during a temperature change volume expansion of the filler balanced and an unacceptable pressure in the cable is avoided.
  • the object is achieved in a wiring harness according to the preamble of claim 1 by its characterizing features, according to which the fixed cross-section of to be fixed by wrapping line network - that is the sum of LeitUngsquerroughe the lines - before wrapping by a parallel to the lines in the Composite introduced elongated line-like body is inserted with a composite variable cross-section.
  • the fixed cross-section of to be fixed by wrapping line network - that is the sum of LeitUngsquerroughe the lines - before wrapping by a parallel to the lines in the Composite introduced elongated line-like body is inserted with a composite variable cross-section.
  • the cable assembly in a known manner by machine, for example, with a winding tape, firmly wrapped.
  • the cross section of the inserted body is reduced, thereby increasing the flexibility of the wiring harness.
  • the winding process can be interrupted even after wrapping the variable in its cross-section elongated body, so that the cross-section is reliably reduced, for example by piercing or cutting the air hose, then the wrapping can be continued become.
  • the diameter of the body and thus its share of the cross-section of the cable network can be varied, whereby the flexibility of the cable harness can be varied and predetermined.
  • the body can be made of an elastic material and elastically expanded in the composite can be inserted. After wrapping it is relaxed or shrunk.
  • an inflated tube made of a thin-walled plastic or thin-walled rubber is inserted in the inflated state in the line network and from the after filling the filling gas, such as air, is let out, in particular by piercing the same.
  • the hose may protrude from the end of the wiring harness from this or be provided with a lateral approach.
  • the open tube relaxes and shrinks together, thereby reducing the fixed cross-section of the interconnect below the fixed wrap, thereby making the arrangement of the interconnections looser and the overall strand flexibility more flexible.
  • the shrunken tube remains in the wiring harness. Damage to the cable insulation, as they can occur when pulling out a stub from the wiring harness, are reliably avoided, and possibly occurring adhesions are no longer adversely noticeable.
  • a widened elongated conduit-like tube made of a thermoplastic material can also be introduced into the composite.
  • the wiring harness then only needs to be heated for a short time after the wrapping in order to trigger the shrinkage of the pipe and to cause the loosening of the arrangement of the lines and the desired increase in flexibility.
  • Fig. 1 shows four different, with a winding tape 6 on a winding machine to be connected to a flexible wiring harness lines 1 to 4.
  • the fixed cross section of the fixed to be fixed line network is the sum of the four cable cross-sections.
  • An air-filled thin tube 5 round cross-section is attached to this loose cable assembly before wrapping ( Fig. 2 ). Its cross section is about 15% of the fixed cross section of the lines.
  • This loose composite is then fed to the winding device in a known manner and firmly wrapped with winding tape 6, wherein the lines 1 to 4 are pressed against the tube 5, whereby this deformed and partially pressed into the cable gusset and also compressed in response to the winding train.
  • This condition is in Fig. 3 shown.
  • the tube 5 has an irregular cross-sectional shape 7 and still occupies about 10% of the solid cross-section, wherein the pressed into the Kauszwickel areas are detected.
  • the lines 1 to 4 are pressed together, and the wiring harness is slightly biased and stiff by the compressed tube 5 in the direction of the wrapping (6). Now, the tube 5 is opened by piercing, the air escapes, and the fixed cross-section of the cable network decreases under the wrapping (6), so that relaxes the wiring harness.
  • the lines 1 to 4 are now without pressure to each other and have a small margin to each other ( Fig. 4 ). With this state, there is a flexible wiring harness that is sufficiently flexible and thus packaged and easier to transport and easier to install.
  • Fig. 5 a section of the hose 5 is shown.
  • the tube 5 is formed from two superimposed and welded together at the edges (S) PE films.
  • the end portion 8 tapers in the inflated state to the frontal weld. This area 8 protrudes as an approach from the line network out.
  • this may contain calcium stearate or other agents. This is particularly advantageous if the wiring harness in the head area near the ears of the vehicle occupants, z. B. in the upper part of the B or C-pillar or between the sky and vehicle roof is arranged.
