  • Patent number: 5241746
    Abstract: A molded receptacle including an interior wall surface and screw threads formed on the interior wall surface by a mold core. The threads have a predetermined thread profile including root radii substantially corresponding to a desired thread standard and crest radii which are smaller than the root radii. The crests of the threads are deformable after molding to enable the mold core forming the threads to be stripped from the receptacle in a direction substantially perpendicular to the major axis of the threads to provide crests which are deformed from their original molded shape yet dimensioned to fall within the desired thread standard. The receptacle is utilized as a threaded socket having one or more electrical contact members. The socket includes a housing which can be formed as stated above including an interior side wall having the threads, a first closed end, a second open end and a first aperture formed through a portion of the housing.
