Abstract: A coupling member for a connector component that includes an inner sleeve configured to surround a shell and that sleeve is rotatable with respect to the shell in a tightening direction to mate with the mating component and a release direction opposite the tightening direction. The inner sleeve has an interface portion and an engagement member. A spring member is wrapped around the shell adjacent the inner sleeve. The spring member has a first tab end that engages the engagement member. When the inner sleeve is rotated with respect to the shell in the tightening direction, the inner sleeve pushes the first tab of the spring member, thereby loosening the spring member around the shell allowing the inner sleeve to rotate in the tightening direction to engage the mating connector component. The first tab end of the spring member prevents the inner sleeve from rotating in the release direction.

Abstract: The internally threaded coupling ring or nut of a conventional rotational coupling system is replaced with a multi-tined locking ring that traverses the threads in an axial direction and locks onto the external threads of the mating half. The tines are positioned such that the forces are evenly distributed around the connector periphery and an anti-decoupling sleeve is extended over the tines and arranged such that, when the sleeve is in a first position, tangs extending inwardly from the tines are prevented from escaping the threads of the externally threaded mating half, and such that the sleeve may be pulled in an axial direction to permit the tines to more easily clear the threads and thereby facilitate decoupling.

Abstract: An automatically locking bayonet coupling mechanism includes, a linear guide structure for preventing relative rotation between the coupler halves, a sleeve rotatably mounted on one of the coupler halves, a spring captured between the sleeve and the coupler half on which it is mounted to generate a torsional force between the sleeve and the coupler half, an L-shaped groove in the other of the coupler halves, and a bayonet pin extending from the sleeve and arranged to engage cam surfaces defined by edges of the groove. As the coupler halves are pushed together linearly, engagement between the bayonet pin and a first of the cam surfaces causes the sleeve to rotate against the force of the spring. Subsequently, the bayonet pin is caused to engage a second of the cam surfaces that forms a locking ramp.
