Definitions

  • the invention relates to a connector device with at least one connector, the connector having a housing, at least one connector body for connection to an outer conductor of a cable and at least one inner conductor part for connection to an inner conductor of the cable, according to the preamble of claim 1.
  • the connector When assembling cables, their conductors are typically connected with a connector.
  • the connector can be a plug, a socket or an adapter.
  • the term connector used in the context of the invention is representative of all variants.
  • the connector is used to establish an electrical connection with a correspondingly complementary further connector.
  • a plug body is generally provided which is connected to an outer conductor of the cable. Furthermore, the plug connector has at least one inner conductor part which is provided for connection to an inner conductor of the cable.
  • the number of inner conductors or inner conductor parts is not restricted in the present case, with common connectors, in particular HF connectors or connectors for coaxial cables, mostly having only one inner conductor part for connection to an inner conductor of the cable.
  • the known connectors have a housing, preferably a plastic housing, with a receptacle for inserting the at least one plug body.
  • connection of the plug body to the outer conductor of the cable or of the at least one inner conductor part to an inner conductor of the cable can take place with known measures, usually by means of soldering, gluing, clamping or crimping.
  • a connection between the cable and the plug connector can be established by stripping a section of the cable sheath in a first step. This exposes an outer conductor.
  • the outer conductor can be, for example, a braided cable shield.
  • a support sleeve is then crimped onto the braided cable shield in such a way that the braided cable shield protrudes beyond the support sleeve.
  • the protruding cable shield braid can be folded back in a next step and placed over the support sleeve.
  • the front end of the cable can then be stripped further so that an inner conductor of the cable is exposed.
  • the exposed inner conductor of the cable can then be connected to the inner conductor part of the plug connector, preferably in such a way that the inner conductor part is crimped on.
  • the connector is preferably put back on the outer conductor of the cable or the cable shielding braid, which is preferably pulled back over the support sleeve is crimped on.
  • the plug body is reliably connected to the outer conductor of the cable by crimping and the inner conductor part is protected within the plug body.
  • the cable sheath of the cable is stripped preferably 10 to 15 mm behind the connector and a metal clamp is crimped directly onto the cable shielding braid of the cable.
