ABSTRACT:
An electrical connector comprises first and second connector components, each component having a generally circular cross-section oriented perpendicular to a central axis that is common to both components. A rotatable coupling ring is retained on and substantially axially aligned with the first component. This coupling ring has a first end for engaging the second component and axially advancing the first component relative to the second component to urge the contacts of the first and second components into enngagement. The coupling ring also has a second end with a retainer groove that encircles the interior of the second end and that has a bearing surface in a plane substantially perpendicular to the common central axis of the first and second components. A retainer ring snugly engages the interior of the retainer groove. The retainer ring has a resiliently collapsible gap and also has an exterior retainer surface generally parallel to and engaging the bearing surface of the retainer groove. The retainer ring further has a formed lip extending from the exterior retainer surface of the retainer ring toward the common central axis and an interior retainer surface in the plane generally parallel to the exterior retainer surface but facing in the opposite direction. A thrust washer snugly engages the interior retainer surface and the formed lip of the retainer ring. A resilient washer interposed between the retainer ring and a flange on the first component urges the contacts of the first and second components together.
