Abstract
A high voltage connector assembly is disclosed for use with high power apparatus including x-ray devices. The present connector is a pancake-style connector, and interconnects a high voltage cable with the cathode of the x-ray tube. The present connector includes a housing, a socket assembly, and insulating material surrounding the socket assembly to insulate it from the housing. The socket assembly comprises a potting-filled conductive sleeve having a continuously shaped, smooth terminal end. The terminal end of the sleeve forms a triple junction with the insulating material and air present near the sleeve. The continuously smooth terminal sleeve end prevents electrical arcing to occur at the triple junction by reducing field strength at the terminal end and urging the electric field of the socket assembly away from the triple junction. The reduction in electrical arcing propensity allows the x-ray device to operate at relatively higher operating voltages.
