Abstract

A system includes a polymeric housing and a first connector in electrically conductive connection with a first component within the housing. The first connector includes a first extending member formed from a conductive loaded polymeric material. The first extending member is formed such that an interior thereof includes conductive elements within a matrix of the polymeric material so that the interior is electrically conductive and an exterior surface thereof comprises the polymeric material and is less conductive than the conductive interior. The conductive interior of the first extending member is in electrically conductive connection with the first component. The first connector further includes a first extending conductive element in electrical connection with the conductive interior of the first extending member. The first extending conductive element extends from the first extending member to pass through the polymeric housing. A sealing bond is formed between the polymeric material of the first extending member and the polymeric housing.
