Definitions

  • the present invention relates to a plug connector with insulation displacement contact, the plug connector comprising a first and a second housing part according to the preamble of claim 1.
  • WO2013 / 111083A1 discloses a connector in which the wires are pressed into the insulation displacement terminals, which are connected to a contact circuit board, with a separate pressing part suitable for this purpose. Then the contact circuit board with the insulation displacement terminals and the separate pressing part is inserted into a first housing part and closed with a second housing part. Overall, the connector comprises a large number of individual parts that are expensive.
  • DE102013209327B4 discloses a connector with the insulation displacement terminals, wherein the housing consists essentially of three complex parts, wherein two housing parts are rotatably attached to a first housing part. The rotary movement of the two housing parts around the first housing part results in a circular insertion movement when the wires are clamped in the respective insulation displacement connector, so that the insulation displacement terminals and the wires are inevitably bent. As a result, the respective insulation displacement terminal and wire are unnecessarily stressed, which means that the reliability of the contact connection suffers.
  • WO2008 / 071917A1 also discloses a connector with the insulation displacement terminals, wherein the housing consists essentially of three complex parts and the two housing parts are rotatably attached to the first housing part.

  • the at least one tension and pressure relief means preferably comprises the first leaf spring element 5 and at least one further leaf spring element 5, which are connected to one another in one piece and directly without an intervening connecting section.
  • the first central part 50 of the first leaf spring element 5 has the third bending edge 55 laterally and parallel to the central part longitudinal axis, which at the same time represents a connection to a next side of the respective further central part 50 of the further leaf spring element 5. All of the respective central part axes are parallel to one another.
  • the first and the further leaf spring element 5 are bent towards one another via the third bending edge 55 in such a way that the respective central perpendicular of the respective central part 50 points to the longitudinal axis of the cable duct.
  • a plurality of leaf spring elements 5 are preferably connected to one another in this way.
  • the first mechanical contact element 57 is preferably arranged in one of the middle parts 50 or in one of the connecting sections 54.
  • the cutting inlet direction Z and a longitudinal direction of the insertion slot of the insulation displacement terminal 40, in which the wire is inserted or pressed in have the same orientation.
  • the wire itself preferably runs essentially perpendicular to the cutting inlet direction Z, with deviations being conceivable, as is known to the person skilled in the art from the prior art.
  • the plug contact is preferably understood to be an electromechanical plug contact for electrical connection to a matching other plug contact of another plug connector corresponding to the plug connector.
  • the respective plug contact in an assembled state is preferably connected both mechanically and electrically to the respective insulation displacement terminal (40).
  • insulation displacement connector is synonymous with the term insulation displacement contact.
  • the core comprises at least one wire and outer insulation.
