An environmentally protected electrical socket and plug assembly (10) retains environmental security throughout repeated connections and disconnections. The socket and plug assembly includes a socket 100 containing an electrical conductor 85 and adapted to insertably receive a plug 90, an environmental sealant 140 at least partially filling the socket so that the sealant is at least partially displaced from the socket when the plug is inserted into the socket, and an elastomeric containment means 40 having an inset dimple 50 for being outwardly deflected to contain displaced sealant when the plug is inserted into the socket and to urge the sealant back into the socket when the plug is removed.
