  • the solution according to the invention allows the arrangement of a carrier body between the input side and the output side of a connector, which can be specifically designed to reliably absorb forces, such as torsional forces, and which can also (optionally) also be used as a stop and locking means for other components, such as for an outer conductor of the connector, and to hold at least one electrical component that is to be placed on the connector.
  • the cable-side and the output-side contact elements can be connected to the carrier area directly or indirectly (e.g. via an electrical component arranged on the carrier area).
  • the output-side contact elements can be spaced apart from the cable-side contact elements along a longitudinal direction (e.g. the longitudinal direction of the connector, along which the connector is intended to be plugged onto a mating connector); and the two support sections can extend from the respectively associated connection section of the carrier body in directions opposite to one another transversely to the longitudinal direction.
  • the two support sections can, in particular, each run in an arc.
  • the support sections can each have a free end, the free ends of the support sections facing each other.

  • the carrier body and the cable-side and output-side contact elements are arranged at least in sections in the interior space defined thereby.

  • One can respective drain wire 21, 22 may be formed by a core made of steel, which is coated with copper. The coating can be done, for example, by electroplating.

  • each drain wire 21, 22 contains a material with such magnetic properties that the drain wire 21, 22 can be separated from the cores 11, 12 of the cable 1 under the influence of magnetic forces. That is, the magnetic properties of the drain wire 21, 22 must differ from those of a respective wire 11, 12.
  • a support crimp 16 is applied to the plug-side end of the cable 1, which is (optionally) surrounded by a casting 18, for example in the form of a ferrite core filter encapsulation can be.
  • a cable-side (ferrite core) filter functions here as a sheath wave filter, in particular for suppressing sheath waves in the form of high-frequency common-mode interference, which are caused, for example, by electrical devices and which propagate along the cable 1 . That filter is therefore used to eliminate or reduce common-mode interference that occurs in phase on the two parallel wires 11, 12 or the electrical lines 11a, 12a and that in the present example are caused in particular by standing waves.
