An electrical connector having a receptacle including a receptacle shell and a plug including a plug housing, a coupling nut threaded on the plug housing and engaged with a coupling ring, the coupling nut having threaded engagement with the plug housing and the coupling ring having locking flanges engageable with cooperable locking lands on the receptacle shell, the plug and receptacle being adapted to be fully electrically mated and locked by rotation of the coupling ring through about 90 degrees. An arcuate detent member subtending an angle of about 180 degrees is keyed to the plug housing for relative axial movement of the plug housing, and is received within an annular groove in the coupling ring for resilient forcible selective engagement of opposite radially outwardly enlarged ends of the arcuate detent member with two sets of radially outwardly formed recesses in the coupling ring. When the coupling ring is rotated to the fully locked position of the plug and receptacle means, the ends of the arcuate member are forcibly snapped into one set of recesses to indicate attainment of the locked and fully mated position by sound and by feel. Rotation of the coupling ring in the opposite direction unlocks the plug and receptacle and the enlarged ends of the detent member are released from the first set of recesses to engage a second set of recesses in the coupling ring to audibly and tactilely indicate attainment of the unlocked position. The resilient arcuate member comprises an enlarged center portion forming a key which is designated to mate with and ride in a keyway on the plug housing with an enlarged portion of the keyway defining a dog-leg in the path of the axial travel of the plug housing. The key makes audible contact with a terminal wall of the dog leg producing an intensified audible snap when the fully mated and locked position of the connector is attained.

In an electrical connector having receptacle means including a receptacle shell; a plug means including a plug housing; a coupling nut threaded onto said plug housing; a coupling ring keyed to said coupling nut; electrical contact elements carried within said receptacle shell and said plug housing for electrical mating and unmating; lock means on said coupling ring and said receptacle shell for releasably holding said contact elements in mating relation; means for audibly indicating fully mated and locked relationship of said receptacle means and plug means, said indicating means including an annular groove in said coupling ring, a keyway on said plug housing, and an arcuate spring detent in said annular groove and having a key engaged in said keyway, said detent having radially outwardly directed end portions carried by resilient arcuate arms which are bent when the end portions thereof are between spaced sets of radially outwardly directed recesses in said annular groove during turning of said coupling housing, whereby said end portions snap into a set of recesses to produce an audible sound to indicate fully locked or unlocked position of the receptacle means and plug means, the improvement comprising: an enlarged portion defining a dog-leg in said keyway in the path of axial travel of said plug housing whereby said key makes audible contact with a terminating wall of said dog-leg so as to produce an intensified audible snap indicating attainment of the fully mated and locked position of the connector.
