CONTACT FOR AN ELECTRICAL CONNECTOR PROTECTED BY A POLYMER FILM AND ITS PRODUCTION PROCESS

摘要

The invention relates to a contact for an electrical contactor protected by a polymer film and to its production process. This contact (3 or 7) has a contact resistance of at the most 10 ohms and incorporates a base metal coated by a 5 to 500 nm, homo- geneous, adhesive organic polymer film. The polymer film can be deposited by the electropolymerization of a monomer such as acrylo- nitrile, followed by a heat treatment or irradiation to improve its electrical conductivity, so that a contact resistance not exce- eding 10 ohms is obtained.
