ABSTRACT:
A tubular female receptacle receives the projecting end of a cylindrical male plug shell having a radial shoulder intermediate of its ends, which bears against the end face of the receptacle. The plug shell carries a tubular coupling ring with cam grooves in its inner surface to act against bayonet pins mounted to the periphery of the receptacle. When the coupling ring is rotated onto the receptacle the cam grooves and bayonet pins cause the coupling ring to advance axially over the receptacle, and because the coupling ring is carried by the plug shell, the coupling ring causes the plug shell to advance into the receptacle. The cam grooves must necessarily end in detents to prevent the bayonet pins from backing down the ramps defined by the grooves. A threaded fitting threaded into the back end of the coupling ring is tightened into the coupling ring to lock the bayonet pins in the detents and at the same time to rigidly lock the plug shell, via its radial shoulder, to the receptacle, in metal-to-metal contact with the same.
