Abstract: A method for making an electrical connector comprises the steps of configuring a housing and contact members such that the contact members may assume positions in the housing which are variable for each contact member and of assembling the contact members in the housing such that they assume positions therein giving rise to contact member coplanarity. An electrical connector so made comprises a housing defining contact member receiving channels and contact members resident in the channels, the contact members defining contact portions and contact member retaining means, the housing being configured to permit variable positioning of said contact member retaining means therein, whereby contact member contact portions may be coplanarly positioned irrespective of warp present in the housing.

Abstract: This invention is an anti-decoupling mechanism for an electrical connector assembly of the type having two housings (20, 50) connected together by a coupling ring (30). The invention is characterized by an annular member (10) that has a plurality of slots (11) around the periphery thereof that engages the projection (41) on each spring (40) mounted within a coupling ring (30).

This anti-decoupling arrangement provides a first lower pressure against the spring (40) during the initial stage of the coupling cycle and a second higher pressure against the spring during the final stage of the coupling cycle thereby reducing the wear on the anti-decoupling mechanism an increasing its effectiveness.
