  • Patent number: 5496189
    Abstract: An electrical connector assembly (10) of the type having a pair of mateable cylindrical plug and receptacle shells (18,22) secured together by a rotatable coupling ring (16). The connector assembly is provided with a decoupling retardation mechanism which includes engageable teeth (34) on the interior of the coupling ring (16) and a pair of leaf spring members (46,72) mounted to the plug shell (18) inwardly of the teeth (34). The leaf spring member (46,72) includes a fixed beam portion (62,82) having a projection (64,84) which engages the teeth (34). The sides of the teeth and the projection are steeper on one side than the other. The steeper side is the one which is engaged when the coupling ring (16) is rotated in the direction to decouple the shells (18,22). Accordingly, greater torque is required to decouple the shells than to couple the shells.
