  • the invention relates to a connector with contacts on a circuit board etc. can be attached, a housing, an insulating body, which is arranged in the housing and carries the contacts, and at least a locking part, by means of which a complementary connector, which can be provided with a cable, locked to the connector can be.
  • the fixed connector that directly can be attached to the circuit board or to a housing, etc.
  • the contacts of the fixed connector are usually with the circuit board connected, for example by pressing and soldering or by Solder on.
  • the complementary connector can connected, which is referred to as a loose connector and is used in particular to connect in cables to the fixed connector.
  • the fixed one Connector provided with the locking part, which in particular as Mother or can be designed as a locking hook.
  • the loose connector is then provided with a screw or with complementary locking hooks, so that it can be locked to the fixed connector, whereby the two connectors cannot be unintentionally disconnected can, for example when pulling on the cable.
  • Tractive forces are via the screw and the nut or the locking hook on the fixed connector and from this to the circuit board or transfer the housing wall.
  • the object of the invention is therefore to provide a connector create, in the event of any tensile forces exerted on him are not derived from the contacts.
  • This task is performed by a connector of the type mentioned solved, which is characterized in that the locking part with at least a hook is provided, which the locking part on the circuit board etc. can anchor, and relative to the housing and the insulating body is slidable between two stops.
  • the locking part engages So directly on the component, for example on the circuit board, in which the Tensile forces are introduced from the loose connector, so that the contacts are not required for power transmission. Since also the locking part relative to the housing and the insulating part of the fixed connector is displaceable, it reliably prevents tensile forces occurring must be accommodated by the housing and the insulating part before they can be transferred to the locking part.
  • the locking part has a sleeve with an internal thread
  • a spreader pin which is received in the sleeve, and two hooks by the spreader pin from a press-in position into an anchoring position can be spread.
  • a loose connector with screws record which can then be screwed into the sleeve to the to fasten the two connectors together. Tractive forces that occur are then directly from the loose connector via the screw in the locking part and derived from this in the circuit board without that the contacts of the fixed connector are loaded.
