Abstract
A device for transferring electrical power between a frame and a closable member such as a door includes a first housing and face plate disposed in an opening in the frame and a second housing and face plate disposed in an opening in the closable member edge. The openings are positioned so that when the closable member is closed the openings are aligned. A hollow elbow assembly is rotatably disposed and secured in each hole. A tube having a pivot guide at each end is rotatably and axially slidable in each elbow assembly. A slot in each elbow assembly allows the tube to pivot. A wire bundle in the tube is connectable to wire leads. Boots may be supplied around the tube/elbow assemblies' junctions to exclude water. Thus, the wire bundle is fully contained within a protective, articulated, armored sheath to prevent wear, chafing, breakage, and vandalism.
