Abstract:
Apparatus for coupling together a pair of mating connectors in a bayonet-type arrangement comprising:a first mating connector shell and a second mating connector shell, the two shells having matching configurations to permit joining together of the associated mating connectors to provide an uninterrupted, hermetically sealed path through said connectors when joined; the first mating connector shell having a plurality of spiral grooves spaced about its periphery for receiving a corresponding plurality of retaining members in a releasable bayonet-type coupling; a coupling ring having a plurality of retaining members corresponding in number and spacing to said plurality of spiral grooves for engaging said spiral grooves of said first matching connector shell to establish said releasable bayonet coupling during rotation of the coupling ring relative thereto; said coupling ring and said second mating connector shell having a cooperative structural configuration which permits the ring to rotate while limiting axial movement of the ring relative to the shell such that as the coupling ring is rotated in a direction to propel said retaining members along said spiral grooves toward a locking position, the ring draws the two mating connectors and associated connector shells together to establish said coupling; a circular gasket mounted on one connector shell in a position to bear against a sealing surface on the other connector shell to establish a compression seal for the joint between the pair of mating connectors, the extent of compression of the gasket being determined by the retention of said retaining members in said bayonet-type coupling; and a coupling nut support element encircling and engaging portions of said coupling ring and said second mating connector shell for increasing the compression of said gasket against said sealing surface and rigidizing said coupling by drawing said second connector shell toward said first connector shell in a rigid juxtaposition.
