ABSTRACT:
A cord terminating plug includes an unipartite, non-hinged, dielectric housing with a free end and a cord input end which opens to a cavity and with provisions for preventing ingress of moisture and other contaminants. A cord jacket anchoring member disposed within a well is formed integrally of the housing through a connecting hinge oriented toward the free end and a frangible portion oriented inward the cord-input end. The anchoring member has two intersecting externally facing surfaces with one of the surfaces having a stop formed thereon. Forces are applied to the anchoring member to disconnect it from the housing through the frangible portion and move it pivotally into clamping engagement with the cord jacket. A portion of the anchoring member adjacent the intersection of the externally facing surfaces is compressed and then reformed with the stop engaging a wall which defines the well and with portions of the one surface engaging an inwardly facing surface of the cavity adjacent the cord-input end of the housing, the dual engagement of the stop and the one surface with the housing maintaining the anchoring member in locked engagement with the cord. Another portion formed integrally with the housing is reformed to provide strain relief for the cord conductors. Terminals inserted into the dielectric housing engage with the conductors and have external contacting portions positioned for engagement with associated components of a telephone apparatus when the plug is inserted thereinto.
