US Patent 6932390 Swivel fitting

A swivel fitting comprising a tubular entry member and a tubular exit member, the internal diameter of the tubular exit member being larger than the internal diameter of the tubular entry member, thus facilitating the transition of an inserted cable or cable or wire bundle from the tubular entry member to the tubular exit member even when the connector is configured at an angle of less than 180 degrees. Planar, relatively rotatable and mating flanges located at the exit end of the entry member and the input end of the exit member provide a common centerline and are joined by means of a threaded collar, thereby permitting configuration of the swivel fitting at angles between about 90 and 180 degrees.
