Definitions

  • the present invention relates to a longitudinally sheathed, elongate item, in particular a sheathed cable harness, with a cable bundle, comprising one or more electrical lines, and with an electromagnetically shielding covering for the cable bundle, the covering comprising an adhesive tape with a carrier and with an adhesive layer, and wherein an electrically conductive layer is present in the envelope.
  • the invention relates to the use of a covering for the production of an electromagnetically shielding longitudinal covering of elongate goods, in particular a cable harness.
  • Electrical lines in particular lines through which alternating current flows, emit electromagnetic waves that form interference fields and thus influence electrical or electronic components and can induce interference currents in other electrical lines.
  • the frequency range of such electromagnetic waves caused by electric drives extends from a few Hz up to approx. 25 kHz.
  • WLAN Wireless Local Area Networks
  • TPMS tire pressure monitoring systems
  • Shielding is therefore regularly used, especially in the case of lines that are heavily energized or lines that are particularly sensitive to alternating electromagnetic fields, such as antenna cables or - more recently - in particular cables for digital image and sound transmission (HDMI: High Definition Multimedia Interface).
  • HDMI High Definition Multimedia Interface
  • the insulated current-carrying conductors are usually covered with a close-meshed copper mesh and/or with aluminum foil, which in turn are grounded and thus prevent radiated interference.
  • electrical cables can be protected from external electromagnetic radiation.
  • Typical shielding attenuation values of such sheathed cables are > 60 dB in a frequency range of 0.1 MHz - 500 MHz.
  • the shields mentioned are usually held in place and electrically insulated by an outer, extruded plastic jacket.
  • the cables In order to mechanically protect the plastic sheath and the underlying shielding and the actual insulated conductor, the cables often have to be additionally protected by protective hoses or cable wrapping tapes applied in a helical manner. In this way, several lines running in parallel can also be bundled into a line set.
  • the wiring harnesses then consist, e.g. B. especially in the automotive industry, from a variety of cable bundles that can branch at short intervals.
  • sheathed cables in which several cables running in parallel are already bundled during cable manufacture, are suitable for such branched constructions poorly suited.
  • individual cables are usually bundled and branched according to the requirements and only finally encased in a cable protection system.
  • the prior art also includes hoses and sleeves made from conductive fabrics or combinations of conductive fabrics with layers of plastic that enclose these fabrics. What they have in common is that they are comparatively complex to manufacture and have a fixed inner diameter.
  • the disadvantage is that such coverings either have to be precisely adapted to the outer circumference of the item to be covered or that, if a uniform diameter is used for the covering, low filling levels may have to be accepted.
  • low fill levels not only mean an excessive use of material, but also imply insulating layers of air, which in the case of lines with high currents mean that the heat can be poorly dissipated and the heating leads to an undesirable increase in the conductor resistance. It is therefore desirable to have thin protective layers that fit as closely as possible to the item to be wrapped.
  • Copper braiding in particular, but also the subsequent steps for grounding, protection or bundling are not only complex and expensive, but also contribute significantly to the weight of a wiring harness.

  • the electromagnetically shielding intermediate layer can consist of a conductive fabric or a metal foil and is completely covered on both sides by the textile layers.
  • the cover is laboriously sewn on one longitudinal edge and thus forms a channel through which cables can be pulled.

  • Mention is also made of a grounding wire, e.g. B. can be formed by a weft of a conductive fabric.
