Abstract:
An electric plug connection comprising:a plug pin and a plug receiver for receiving the plug pin, (said pin having a cylindrical wall terminating in a section of reduced diameter) said plug receiver comprising an axially compressible coil spring and a receiving chamber enclosing individual turns of the coil spring;wherein at least one of the turns of said coil spring is a smaller diameter contact turn having a diameter smaller than a diameter of said plug pin for making contact with said pin upon insertion of said pin into said receiver;wherein other ones of said turns of said spring are larger diameter turns having substantially equal diameters which are larger than a diameter of said pin in a case of non-insertion of said pin into said receiver; andlarger diameter turns of said spring which are situated ahead of said at least one contact turn, in a direction of insertion of the pin, are axially spaced apart from each other, the longitudinal of said smaller diameter turn is displaced laterally from the longitudinal of said larger diameter turns prior to insertion of the plug pin thereby to improve contact between the pin and a larger diameter turn upon insertion of the pin into the smaller diameter turn.
