ABSTRACT:
A connector accessory for electrical connectors containing a detent or locking member or members for preventing disconnection from an attached connector when the assembly is subjected to vibration, shock or other stresses. The accessory consists of a coupling and a body containing the accessory which in one form is a detent and in another form serves as a detent in one direction of rotation and a permanent or temporary lock in the other direction of rotation. The coupling is provided with screw threads to engage an accessory thread at the rear of an electrical connector and the body contains features which are required to provide proper mechanical and environmental interface characteristics to mate with various electrical connectors, i.e., teeth, splines, seals, etc. When the accessory is mated to an electrical connector, the rotation of the coupling is restricted by a spring and tooth mechanism interfacing between the coupling and the body to prevent the coupling from counter-rotating and allowing the accessory to become loosened or separate from the back of the connector. This concept may also be employed on a connector coupling ring as well.
