An electrical connector having means providing a signal when the connector members are fully engaged. The coupling nut on one connector member carries a detent pin which engages a mating recess in the shell of the connector member when the member is fully coupled to its mating connector member. When the detent pin engages the recess, an electrical indicator circuit is closed providing a signal that the connector members are mated. A releasable lock ring is also provided on the coupling nut which maintains the detent pin engaged with the recess.

DETAILED DESCRIPTION According to the principal aspect of the present invention, there is provided an electrical connector in which one of the connector members has a coupling nut thereon to effect interengagement of the two members.
When the coupling nut fully engages the two connector members, the contacts are fully mated and the peripheral and interfacial seals are established.
Detent means is carried on the coupling nut which is releasably engaged with the shell on which the coupling nut is mounted.
Releasable means locks the detent means into engagement with the shell when the connector members are mated.
When the detent means lockingly engages the shell, a clicking noise results providing an audio indication of the fully mated condition of the connector.
In the preferred embodiment, when the detent means is so engaged, an electrical circuit is closed energizing a signalling device providing an additional indication that the connector members are fully mated.
The fully mated condition may also be noted by free rotation of the lock means on the coupling nut.
Thus, the invention provides redundant signalling means for indicating the full engagement of an electrical connector.
