Abstract
A high voltage connector is formed of a composite pultruded member that has an inner core including a plurality of high resistance electroconductive strands carried in a resin binder. The inner core is surrounded by an outer nonconductive shell, and extends from a laser cut end of the outer shell to a contact face. During formation of the contact using laser techniques, portions of the outer shell are removed to expose the inner core, the resin binder of the inner core may be removed, and the strands of the inner core may be fibrillated and patterned as desired. In one embodiment, the resistance of the strands of the inner core of the high voltage connector provide a load resistor for a circuit to which the connector may be connected.
