Abstract
In a connector plug with a locking mechanism which can be locked to the mating socket, no matter what part of the plug may be gripped when inserting it into the mating socket, and can be unlocked only by pulling a tubular member of the plug, an insulating body holding pin contacts is disposed in a cylindrical front half portion of a metal cover whose rear half portion is semi-cylindrical. The cylindrical portion of the metal cover has cut therein U-shaped grooves, defining tongue-shaped locking pieces each having a protrusion. The semi-cylindrical portion of the metal cover has attached thereto a metal clamper for clamping a cable and is covered with a semi-cylindrical auxiliary cover to form a rear cylindrical portion. Elastic support pieces of a resin material for supporting the tongue-shaped locking pieces on the inside thereof are axially slidably mounted in the cylindrical portion of the metal cover, and the elastic support pieces are forwardly biased by a coiled spring disposed around the metal cover. The rear half portion of the metal cover and the auxiliary cover are received in a cap of a resin material, and the entire plug structure is housed in the tubular member of a resin material in such a manner that the elastic support pieces can be moved back.
