Abstract
LE DISPOSITIF DE CONTACT ELECTRIQUE EST UNE VARIANTE DE CEUX QUI SONT DECRITS DANS LE BREVET PRINCIPAL. L'ENSEMBLE CONSTITUE PAR LA PAROI EN MATERIAU DIELECTRIQUE ET LE MATERIAU CONDUCTEUR FORME UN MATERIAU COMPOSITE DIELECTRIQUE-CONDUCTEUR ET LE CONDUIT EST PERCE DANS LA PARTIE DIELECTRIQUE JUSQU'A LA PARTIE CONDUCTRICE. LE MATERIAU COMPOSITE EST UN METAL EMAILLE, OU UN METAL SUR LEQUEL EST DEPOSE PAR SHOOPAGE UN DIELECTRIQUE, OU UNE PLAQUE DIELECTRIQUE SUR LAQUELLE EST DEPOSE PAR SHOOPAGE DU METAL, OU UN CERMET DONT ON A ELIMINE SUPERFICIELLEMENT LA PHASE METALLIQUE. LE CONDUIT EST CYLINDRIQUE OU CONSTITUE PAR UNE FENTE, OU PAR DES FENTES SE CROISANT A ANGLE DROIT. UTILISABLE POUR DE NOMBREUX TYPES DE CONTACT ELECTRIQUE.
