Abstract: A releasable electrical connector consisting of a connector plug mating with a corresponding connector receptacle which may be disconnected by a separating force applied to a surrounding operating sleeve and the connectorl receptacle. The operating sleeve is shifted axially by the separating force against the bias of compression springs to a release position. The springs are received within grooves formed along the exterior of a segmented spring retaining housing, the segments forming an anchoring flange disposed within a recess formed about the connector plug. A plurality of arcuate threaded coupling segments assembled within the operating sleeve provide a threaded coupling, which segments in the nonreleasing position of the operating sleeve are positioned radially inward to mate with a corresponding thread on the receptacle and serve to create a mating force between the receptacle and plug upon rotation of the operating sleeve and to retain the connector and plug in the connected position.

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.

Abstract: An electrical connector assembly having a plastic disc (30) adjacent a moisture sealing grommet (20) to prevent radial forces applied to a wire (40) entering the grommet from deflecting the passage (21) in the grommet and allowing moisture to enter the passage (21).

Abstract: An electrical connector assembly in which the electrical connectors are capable of being quickly and easily coupled and decoupled with mechanism for preventing accidental decoupling of the connector through vibration. The coupling and decoupling is accomplished by a coupling nut mounted to one electrical connector, with the coupling nut having a screw thread adapted to receive a screw thread on a second connector. The connector assembly is adapted to remain coupled to said first housing by a spring mounted to the coupling nut and engaging ratchet teeth carried on an edge of the housing. The ratchet teeth are more steeply angled on the leading edge engaged during decoupling and more gradually angled on the leading edge during coupling, allowing for an ease in coupling and a greater resistance to decoupling.
