Abstract
Abstract An electrical connector comprises a connector plug part and a connector receptacle part, each part comprising a molded insert and a metal cylindrical shell within which the insert is fitted and retained. The insert of the receptacle part has passageways therethrough in which are secured electrical pin terminals and an integral hood which extends beyond the mating face of the receptacle insert and the shell of the receptacle part also has a hood which extends forwardly beyond the insert hood. The plug part comprises an insert in which passageways extend therethrough in which are secured electrical receptacle terminals and a shell which has an internal surface that is radially spaced from the external surface of the plug insert so that when the two parts are mated, the hood of the receptacle insert will be received between the external surface of the plug insert and the internal surface of the plug shell. The hood of the receptacle shell extends over the external surface of the plug shell when the parts are mated and threads or the like on the external surface of the receptacle shell hood are engaged by threads provided on the internal surface of a metal coupling ring which is rotationally mounted on the plug shell. A pin member extends across the threads and engages a groove in the threads of the receptacle shell hood and the coupling ring to provide an audible and tactile indication of a fully-mated condition of the plug and receptacle parts.
