Definitions

  • the invention relates to an electrical connector which is constructed in two parts, the two cuboid parts being slidable against one another and being able to be latched to one another in two stages, wherein a housing part made from stamped sheet metal parts stores insulation displacement contacts formed in housing chambers, the insulation displacement terminals of which protrude from the housing and in the other housing part are electrical individual lines, which are contacted with the insulation displacement contacts of the insulation displacement contacts when the housing is locked in the second stage, and wherein the plug has openings for engaging through mating contact elements of a mating connector or the like electrical component for contacting contact spring arms of the insulation displacement contacts.
  • the latching means in one housing part are designed as latching brackets which engage behind the latching webs on the other housing part.
  • These locking means require a relatively long design of the connector. When the housing parts are pushed together, tilting of the housing parts cannot be ruled out, especially since the locking brackets are not stiff enough to act as a guide element. Tilting can lead to incorrect contacts.
  • the object of the invention is in such an electrical Small-sized plug to create a relatively short design, which enables easy assembly of the plug, ensures reliable, uniform electrical contact with the insulation displacement contacts of the insulation displacement contacts and with a mating contact element, and permits automatic checking or checking of the insulation displacement contact.
