Definitions

  • the present invention relates to a preassembled cable with the features of patent claim 1.
  • the present invention also relates to a cable connector arrangement with the features of patent claim 10.
  • the present invention relates to an electrical plug connection with the features of patent claim 15.
  • a shielded cable in which at least one inner conductor is encased by an outer conductor is typically used for the transmission of high-frequency signals.
  • the electromagnetic wave is guided in an electrically insulating insulator between the inner and the outer conductor.
  • the outer conductor also serves as a shield.
  • the shielding protects the electromagnetic wave carried in the shielded cable from high-frequency interference from the outside of the cable and at the same time prevents the electromagnetic wave carried in the shielded cable from being radiated to the outside.
  • the shielding or the outer conductor of the shielded cable is typically formed by a combination of a shielding film and a shielding mesh surrounding the shielding film.
  • the combination of shielding foil and shielding mesh combines the good shielding attenuation of the shielding foil at higher frequencies with good Shielding attenuation at low frequencies and the better mechanical properties, in particular the high breaking strength, of the shielding braid.
  • a shielding foil is typically made of a dielectric foil which is coated on both of its lateral surfaces, i. H. on its inner wall and on its outer wall, is coated with a metallic coating.
  • a shielding film designed in this way can transmit an electromagnetic wave between the two metallic coatings.
  • the two-wire system of the shielding film is connected in series to the two-wire system of the inner conductor and the inner-wall coating of the shielding film of the actual cable transmission path.
  • the overall impedance of the cable is falsified by the impedance of the two-wire system of the shielding film and no longer matches the impedance of the connector. This mismatch causes reflections and thus an additional loss of signal energy to be transmitted.
  • the object of the present invention is to specify a technical solution in which the signal losses in the actual transmission path of the shielded cable due to an undesired feeding of the high-frequency signal into the shielding film are reduced.
  • this object is achieved by a prefabricated cable with the features of claim 1.
  • the electrically conductive connection is particularly preferably formed in an end region of the shielding film on the connector side, but can in principle be formed in any region of the shielding film within the scope of the invention.
  • the metallic coating of the outer lateral surface can also be referred to as the first metallic outer coating of the film and the metallic coating of the inner lateral surface as the second metallic outer coating of the film.
  • the foil thus preferably forms, in cross-section, a stack of first metallic outer coating, followed by the dielectric material, followed in turn by the second metallic outer coating.
  • the inner lateral surface of the film runs on an outside of the film facing away from the outer lateral surface of the film; the two lateral surfaces particularly preferably extend on the outer sides of the film running parallel to one another.
  • the outer surface of the film faces away from the cable center or from the longitudinal axis of the prefabricated cable and the inner surface of the film faces the cable center or the longitudinal axis of the prefabricated cable.
  • the finding/idea on which the present invention is based consists in electrically connecting the metallic coatings of a dielectric material to one another in the shielding film of a cable via at least one electrically conductive connection.
  • the electrically conductive connection between the metallic coating on the outer lateral surface and on the inner lateral surface is preferably formed in an end region of the shielding film on the connector side.
  • the two-wire system of the shielding film is short-circuited via the electrical connection of the two metallic coatings on the plug-side end area of the shielding film.
  • An electromagnetic wave can thus advantageously no longer be fed into the shielding film from the connector in the cable transition. Parasitic guidance of the electromagnetic wave in the shielding foil is prevented.
  • the short-circuited two-wire system of the shielding film no longer falsifies the overall impedance of the cable transmission system.
  • the overall impedance of the cable transmission system is thus matched and avoids unwanted reflections of the electromagnetic wave.
  • the resonant effects that falsify the load impedance in a specific frequency range compared to the matched characteristic impedance can thus be avoided.
  • the electrical connection between the metallic coatings on the outer lateral surface and the inner lateral surface of the preferably hollow-cylindrical shielding film can preferably be formed on the plug-side end area of the prefabricated cable.
  • the braided shielding and thus also the shielding foil located radially inside the braided shielding are exposed from the cable sheath during the assembly process.
  • the shielding film is thus easily accessible in the plug-side end area of the prefabricated cable during the fabrication process and can be easily processed with regard to an electrical connection between the two metallic coatings.
  • the individual electrical connection can each be an electrically conductive connecting element, for example a metallic cap, a metallic pin, a metallic sleeve, a metallic wire, a metallic clip, a metallic platelet, a metallic spring, a Connecting element made of an electrically conductive elastomer - ie an elastomer with integrated metal particles - be a metallic wire mesh or any other electrically conductive or metallic connecting element with a suitable shape.

  • the individual electrical connection can be non-positively connected to the metallic coatings of the shielding foil (for example when crimping the shielding foil and the braided shielding with the outer conductor contact element).
  • a material connection solddering, welding or gluing (in the case of electrically conductive elastomer)
  • a form-fitting connection is also conceivable.
  • the electrical connection between the metallic coatings of the shielding film can also be realized by direct electrical contacting of the two metallic coatings by the dielectric film of the shielding film being displaced by suitable processing at a point inside or at the edge of the shielding film.
  • the metallic coatings arranged concentrically to one another are electrically connected to one another over the entire cross section.
  • the area between the two metal coatings of the shielding film is thus completely filled with metal. In this case no electromagnetic wave can couple into the shielding film at all.
  • the front end of the shielding film in particular the front end of the dielectric film of the shielding film, is completely metallically terminated for example with a metallic layer or a metallic cap.

  • folding a strip of the shielding film is understood to mean turning the strip over by 180°.
  • the two metallic coatings of the shielding foil can point in the same direction.
  • the braided shielding or a metallic element, for example the outer conductor contact element of the connector, which cover the non-folded area and a partial area of the folded area of a strip of the shielding foil at the same time and thus make electrical contact, can thus form an electrical connection between the two metallic coatings of the shielding foil .
