  • the movement of the bushing section 14 limited by the jaws 22, provided that the socket section 14 in Direction of the connecting portion 12 is moved.
  • opposite Direction is the movement of the bushing section 14 by the above arranged clamping element 58, on which the spring element 20 with the end face of its end section 26 comes to rest.
  • a twisting of the connector in the connector 10 is through the two Preventing tensioning elements 58 and 60, which are under slight prestress rest on the connector pin of the connector.
  • the depressions 44 on the contact springs 42 ensure that the Connector pin of the connector, which is usually a rectangular or has a square cross-sectional shape, only in the sections of the Clamping area rests laterally on the recess 44 of each contact spring 42.
  • the holding forces caused by the contact springs 42 engage laterally offset to the axis of symmetry of the contact springs 42 on the connector pin so that any forces acting transversely on the connector plug on the connector pin the distance of the point of application of the holding forces Axis of symmetry corresponding holding torque is generated, the pivoting of the connector pin between the contact springs 42 prevented.
  • any transverse forces that may occur on the connector of the contact springs holding the connector pin in a defined position 42 of the socket section 14 transferred to it, which in turn forwards the absorbed transverse forces to the spring element 20, that deforms accordingly.
  • bracket 62 of the sleeve 48 By the distance of the bracket 62 of the sleeve 48 to the elevations 46 on the contact springs 42 between the movement of the socket portion 14 allows the brackets 62 so that the socket portion 14 in a defined range of movement predetermined by the brackets 62 can move relative to the connecting portion 12, wherein the spring element 20 allows movement in the direction of the three spatial axes. Only if that Movement of the bushing section 14 in one direction is so great that one of the elevations 46 of the contact springs 42 on one of the brackets 62 System comes, the movement of the bushing section 14 is limited. In this way, overloading of the spring element 20 is avoided.
  • FIG. 7 shows a diagram in which the restoring force F r caused by the spring element 20 is shown as a function of the deflection of the socket section 14 relative to the connection section 12, which increases with a constant progression from the zero point. Furthermore, the diagram shows the holding force F h exerted by the two contact springs 42, which runs parallel to the legal value axis of the diagram in FIG. 7. If the restoring force F r of the spring element 20 does not exceed the holding force F h of the contact springs 42, the plug pin of the connection plug is not moved with respect to the contact springs 42, but only the socket section 14 is displaced with respect to the connection section 12. Since the connector in this case remains in its predetermined, defined plug position with respect to the contact springs 42 during the movement of the socket section 14, the formation of fretting corrosion is avoided, as indicated in FIG. 7 by the area A in the diagram.
  • a third force F v is shown in the diagram according to FIG. 7, which occurs in a conventional connection socket without a spring element when vibrations occur at the plug connection between the conventional connection socket and the connection plug.
  • the comparative force F v defines the elasticity of the material of the conventional connection socket, which likewise achieves a spring effect, albeit a very small one.
  • the slope of the comparison force F v is very much greater than that of the restoring force F r of the spring element 20 of the connecting socket 10.
  • the comparative force F v exceeds the restoring force F r of the connecting socket 10 according to the invention with a significantly smaller deflection of the socket section, the holding force F h of the contact springs of the conventional connection socket, so that there are relative movements between the plug pin of the connection plug and the contact springs of the conventional connection socket. Consequently, the relative movements in a conventional connection socket compared to a connection socket 10 according to the invention lead to fretting corrosion even with significantly smaller deflections of the socket section.
  • Fig. 8 shows an enlarged perspective view of the connector 10, in which a modified sleeve 90 made of spring steel is used becomes.
  • the structure of the sleeve 90 corresponds essentially to that of the sleeve 48, but with the difference that instead of the L-shaped curved Clamping elements 58 and 60 two clamping elements 92 and 94 on the sleeve 90 are formed, which are spirally curved in cross section and in protrude the connection opening 40 of the socket 10.
  • tensioning elements 92 and 94 are intended to be in addition to those of the contact springs 42 caused holding forces on the connector pin of the connector clamping forces directed transversely to these holding forces on the plug pin be applied, the twisting of the connector pin in Prevent bushing section 14.
