ABSTRACT:
An electrical connector assembly in which the electrical connectors may be quickly and easily coupled and decoupled, with a mechanism for preventing accidental decoupling of the connectors as a result of vibration. The connector assembly includes first and second connectors, which are coupled by the provision of a coupling nut mounted on one connector and having an internal screw thread which is adapted to receive a screw thread on a second connector. The mechanism for preventing accidental decoupling includes a spring mounted to the coupling nut and having a plastic forward face for engaging ratchet teeth carried on the edge of the housing. The ratchet teeth are more steeply on the leading edge engaged during decoupling and more gradually angled on the leading edge during coupling, allowing for easy coupling and a greater resistance to decoupling.
