Snap-together x-ray cable coupling nut assembly
First Claim
1. A snap-together high-voltage plug coupling nut assembly device for retaining a high voltage cable end plug in a threaded high-voltage plug receptacle with receiving sockets, wherein the device comprises:
- a high-voltage cable having an end plug including conducting end pins insertable in the receiving sockets and a protruding flange between the cable and the end plug;
a two-piece retainer ring contacting the flange when assembled and having a snap-fit built-in self-retaining means built into the two-piece retainer ring for securing the two-piece ring together around the cable adjacent to the flange so that the retainer ring is self-retaining on the cable and free to rotate around the cable after snapping together around the cable, said retainer ring having a circular groove around an exterior thereof;
an annular nut having internal threads for engaging the plug receptacle, an interior circular opening sufficiently large so that the nut fits over the flange, and a spring means for snap-fitting in said groove and securing the retainer ring in said annular nut, the retainer ring rotatably within the nut so that the nut and the retainer ring form a snap-together coupling nut assembly and the nut is free to rotate relative to the retainer ring.

Abstract
A two-piece retainer ring is snap-fit together by protruding roll pins in mating holes forming a self-connected ring around a high-voltage cable engaging a cable plug flange. Parallel spring wires intruding into a central opening of a coupling nut engage an exterior groove in the retainer ring with a snap fit forming an interconnected mutually rotatable coupling nut assembly. A bend relief sleeve between the retainer ring and the cable extends away from the retainer ring along the cable. A ridge around the bend relief sleeve engages an interior groove in the assembled retainer ring. A D-shaped cable plug flange engages a D-shaped plug receptacle opening to align plug contact pins with receptacle sockets. Mating threads on the nut and receptacle secure the plug in the receptacle with an extending sleeve on the retainer ring bearing against the flange. Protruding sloping annular surfaces inside the nut and outside the assembled retainer ring mutually engage to force the retainer ring against the plug flange insuring a tight plug fit and ground continuity between the retainer ring and the flange and between the retainer ring and the nut. Relative motion between the sloping annular surfaces and between the retainer ring and the flange breaks surface oxide enhancing ground continuity.

10. A snap-together high-voltage plug coupling nut assembly device for retaining a high voltage cable end plug in a threaded high-voltage plug receptacle with receiving sockets, wherein the device comprises:
-
a high-voltage cable having an end plug with conducting end pins insertable in the receiving sockets and a protruding flange between the cable and the end plug; a two-piece retainer ring adapted for contacting the flange when assembled and having a means built into the two-piece retainer ring for securing the two-piece ring together with a mutually engaging snap together fit around the cable adjacent to the flange so that the retainer ring is self-retaining on the cable after snapping together around the cable; an annular nut having threads for engaging the plug receptacle, an interior circular opening sufficiently large so that the nut fits over the flange, and a means for receiving and retaining, with a snap together fit allowing mutual rotation, the retainer ring rotatably within the nut so that the nut and the retainer ring form a snap-together coupling nut assembly and the nut is free to rotate relative to the retainer ring; wherein the snap-fit built-in self-retaining means of securing the two-piece retainer ring together further comprises a roll pin protruding from at least one piece of the two-piece retainer ring inserted in a tight friction snap fit within a mating hole in the other piece of the two-piece retainer ring; and wherein the connected retainer ring further comprises a circular groove around the exterior of the retainer ring and the means for snap-fitting and securing the retainer ring rotatably within the nut comprises a pair of spring wires inserted through opposing sides of the nut and protruding into the interior circular opening of the nut so that the spring wires form parallel chords within the circular opening and the spring wires engage the exterior circular groove of the retainer ring with a snap-fit allowing relative rotation of the nut and retainer ring.
