Estimating the term…
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, homogeneous, adhesive organic polymer film. The polymer film can be deposited by the electropolymerization of a monomer such as acrylonitrile, followed by a heat treatment or irradiation to improve its electrical conductivity, so that a contact resistance not exceeding 10 ohms is obtained.
A contact for an electrical connector having a contact resistance of at the most 10 ohms, incorporating a base metal covered with a 5 to 500 nanometer thick homogeneous, adhesive organic polymer film consisting according to only one polymer directly polymerized on the base metal, said polymer having a cyclized and unsaturated structure, wherein said cyclized and unsaturated structure is obtained by treatment of said polymer by one of heat or radiation, the radiation being selected from the group consisting of UV radiation and the white beam of synchroton radiation.
