Abstract
Abstract A connector plug includes a plurality of contact pins carried by an insulating body which is installed in a cylindrical metal cover. The cylindrical metal cover has a semi-cylindrical rear portion which is engaged with a semi-cylindrical metal cover piece into a cylindrical form. A separately molded insulating cap is assembled onto the cylindrical metal cover. Within the insulating cap, a cable clamp member having a thickness greater than that of the cylindrical metal cover is secured to a rear end extension of the cover. A cable connected to the contact pins is clampedly held by the cable clamp member.
