ELECTRIC CONNECTOR Russian patent published in 2012 - IPC H01R13/52 

FIELD: electricity.

SUBSTANCE: electric connector consists of a plug receptacle (1) with male contacts positioned (31) within its cavity and movable plug head (2) with female contacts (32) for electric conductors ends connection (25, 26). For fixation of the plug head in the plug receptacle with form closure a shape lock ring is applied that is fitted, with part of its cross section, into the plug head groove passing along the perimeter; during the electric connector locking the ring engages, with the rest of its cross section, into the groove arranged on the inner side surface of the plug receptacle. The shape of the lock ring and the grooves as well as the lock ring material are such that the plug head (2) is taken out of the plug receptacle (1) only by a pull force in excess of a certain threshold value. The plug head (2), connected in the same way, is fixed with its end in the congruent end of the plug movable body (3) with form closure ensured by the fixture ring (4). The force enabling the plug head taking out of the plug receptacle is less than the force retaining the plug head in the plug body with fixture ring connection.

EFFECT: detachable plug performing its function without damage to the plug.
