Abstract

A contact retention clip is provided with a B-stage epoxy resin coating. The clip is installed in the contact cavity of a plastic body under heat and pressure to cause the coating to form its final resin. The resin becomes impregnated into the wall of the cavity to seal micro cracks in the wall which otherwise may lead to voltage breakdowns.
