Abstract: In accordance with one embodiment, an electrical contact has a mating end and a mounting end. The electrical contact includes an electrically conductive base, and a multi-layered coating disposed on an outer surface of the base at the mating end. The multi-layered coating can include a metallic layer of a noble metal or alloy thereat: a layer of anti-tarnish material disposed on the metallic layer, and a lubricant layer disposed on the layer of anti-tarnish material, the lubricant effective to seal at least some wear regions created in the layer of anti-tarnish material due to micromotion of the mating end in use.

Abstract: The invention concerns an electrical connector including a box, at least one electrically conductive track and a plurality of first electrical contacts, the first contacts being designed to come into contact with complementary second electrical contacts of a complementary connection device. In order to reduce the manufacturing cost of such an electrical connector and increase the electronic data transfer capacity through this electrical connector, the invention provides that the first electrical contacts are connected to electrically conductive tracks by joining, and that the box is formed by at least one molded plastic that is at least partially metal-coated to form the electrically conductive tracks.

Abstract: In order to metallise a support made from high temperature polymer, the melting temperature of which is higher than 180° C., it is shown that the stages of cleaning, plasma etching, grafting and then metallising in a metallisation bath can be applied. According to the invention, the metallisation bath is brought to a temperature between 50° C. and 70° C., the plasma being a nitrogenous plasma.

Abstract: Integrated unit (1) having a connector (3) mounted on a printed circuit (2), the connector having a support (4) in which are placed a first blade (5) and a second blade (10) linked to the printed circuit, the first blade having on an upper side (8) of the support, an extension (7) forming an antenna (6). This first blade is preferably formed by the metallisation of the plastic support. The second blade comes into contact with the first blade. The support has a cavity (18) to receive a coaxial plug (25) and thus to switch the connection between the first and second blades, for a new connection between this second blade and the coaxial plug.
