ABSTRACT:
A resistor housing includes passageways to accommodate high potential electrical connectors. Connection is made from one of the connectors through a high voltage cable assembly to one output of a power supply. The cable assembly includes a length of high voltage, high-flex, shielded coaxial high voltage cable. The center conductor of the cable is finished at both ends with a banana plug. The shield of the cable is terminated. A sleeve of, for example, heat-shrinkable semi-rigid, multiple wall polyolefin, is slipped onto the stripped end of the cable over the exposed shield and the end of the cable jacket. A length of heat-shrinkable tetrafluroethylene (TFE) is slipped over the sleeve and the adjacent region of cable jacket, shrunk, and trimmed flush with the end of the polyolefin sleeve. Paint or solvent from a trigger/dump/solvent manifold is supplied through a feed tube. The feed tube is constructed from an electrically non-conductive material. Toward the feed tube's distal end, an electrically conductive pin is press fitted into a passageway which extends transversely across the longitudinal extent of the feed tube. Coating material passing through the feed tube is charged as it passes the pin owing to the close spacing of the ends of the pin to a rotary atomizer drive shaft through which the feed tube extends.
