ABSTRACT:
A plug for terminating a cord includes an unipartite, non-hinged, dielectric housing with a free end and a cord-input aperture in the other end and with internal surfaces defining a cavity. A jacket anchoring member is formed integrally of the housing and has a surface which protrudes into the cavity slightly beyond the adjacent surface of a portion of the remainder of the housing adjacent the cord-input aperture when the anchoring member is in an initial position. Forces are applied to the anchoring member to partially disconnect it from the housing and move it into an actuated position with substantially all of the protruding surface in clamping engagement with the jacket and with a portion of another surface of the anchoring member into locking engagement with a portion of the remainder of the housing adjacent the cord-input end of the housing. Another portion formed integrally with the housing is reformed into a strain relief element in engagement with the conductors. Terminals are inserted into terminal-receiving openings in the dielectric housing to move internal contacting portions thereof into engagement with conductors of the cord. External contacting portions of the terminals engage electrically associated components of a telephone apparatus when the plug is inserted thereinto. The arrangement is such that the locking engagement of the anchoring member with the remainder of the housing is maintained during the application of retrograde forces to the cord by a customer during use.
