Abstract: front page image
(EN)This contact member is provided with a contact layer comprising a plate-shaped porous medium having a high-melting metal as a main component, into which an infiltrant having a low-melting metal as a main component has infiltrated; a contact layer support part comprising the infiltrant; and a contact-part-holding conductor. The porous medium has an opening part at the position which is the center of the contact layer, and the infiltrant is formed continuously from inside the opening part up to the contact-part-holding conductor.
(FR)L'invention concerne un élément de contact qui est pourvu d'une couche de contact comprenant un milieu poreux en forme de plaque contenant un métal à point de fusion élevé en tant que composant principal, dans lequel un agent d'infiltration contenant un métal à bas point de fusion en tant que composant principal est infiltré; une partie de support de couche de contact comprenant l'agent d'infiltration; et un conducteur de maintien de partie de contact. Le milieu poreux a une partie d'ouverture au niveau de la position qui est le centre de la couche de contact, et l'agent d'infiltration est formé en continu depuis l'intérieur de la partie d'ouverture jusqu'au conducteur de maintien de partie de contact.
(JA)本発明の接点部材は、低融点金属を主成分とする溶浸材が溶浸された、高融点金属を主成分とする板状の多孔質体からなる接点層と、溶浸材からなる接点層支持部、接点部保持導体とを備え、多孔質体は接点層の中央となる位置に開口部を有し、溶浸材は開口部の中から接点部保持導体にまで連続して成形されているものである。
