An electrical connector assembly for connecting a first contact to a second contact is disclosed including a receptacle member and a plug member. The receptacle member has a recess at one end defined by a resilient wall having an outer end terminating in an inwardly projecting lip and includes means for supporting the first contact in a manner such that the contact extends into the recess. The plug member has a projection at one end defined by a neck portion having an inner end terminating in a contact-receiving face and includes means for supporting the second contact in a manner such that the contact extends within the projection. The plug member also has a collar positioned along the neck portion so that the first contact mates with the second contact prior to engagement of the lip with the collar. With these features of construction, the neck portion is formed no larger in transverse dimension than the lip whereby the neck portion can be inserted into the recess free of interference until after the critical mating function has occurred.

Environmental connector assembly

An electrical connector assembly having plug and receptacle members and a bayonet-type coupling mechanism is constructed to provide improved shielding from electromagnetic interference (EMI). The shells of the plug and receptacle members abut in metal-to-metal, continuous peripheral contact and the uniquely configured interfacial seal of the assembly is designed to assure the achievement of the metal-to-metal engagement. A peripheral face seal is also provided again to assure metal-to-metal abutment and enhance EMI shielding.
