Abstract
Abstract A DIN-type plug connector for shielded cable has a one-piece metal shell member in which a housing member has first been inserted and secured. An inwardly-directed projection is stamped into the side surface of the shell member to secure the housing member therein, after which contact-terminated conductors of the cable are inserted through a rear section of the shell member and into housing passageways. The braid of the cable is placed around the rear shell section and a crimping ferrule is crimped therearound, terminating the braid. A rear section of the ferrule is crimped to the outer jacket cable, and an insulating cable guard placed around the assembly. A polarizing U-shaped channel can be stamped into the shell member forwardly of the housing member therewithin for polarized mating with a receptacle. The housing member can have a U-shaped recess therealong to serve as a polarizing indicator and the shell's U-shaped channel can be formed in alignment therewith becoming a polarizing means. A method is provided for assembling the plug connector.
