Title (EN) CONTACT TERMINAL STRUCTURE
(FR) STRUCTURE DE BORNE DE CONTACT
(JA) 接触端子構造
Abstract:
(EN) [Problem] To provide a contact terminal structure having excellent durability, which is not susceptible to increase in the contact resistance even if on/off operations are repeated in cases where the contact terminal structure is applied to a movable contact terminal. [Solution] A contact terminal structure which is characterized by being obtained by forming a first plating layer on the surface of the base and forming a second plating layer, which serves as the outermost layer, on the surface of the first plating layer. This contact terminal structure is also characterized in that: the first plating layer is formed of a silver tin alloy; the second plating layer is formed of silver or an alloy mainly composed of silver; and the hardness of the first plating layer is larger than the hardness of the second plating layer. The first plating layer has a Vickers hardness of 250-400, and the second plating layer has a Vickers hardness of 80-200.
(FR) La présente invention concerne une structure de borne de contact qui présenterait une excellente durabilité et dont la résistance de contact ne serait pas susceptible d'être augmentée même si des opérations de marche/arrêt sont répétées dans des cas où la structure de borne de contact est appliquée à une borne de contact mobile. L'invention concerne donc une structure de borne de contact qui est caractérisée en ce qu'elle est obtenue par formation d'une première couche de revêtement sur la surface de la base et d'une seconde couche de revêtement, qui sert de couche la plus externe, sur la surface de la première couche de revêtement. Cette structure de borne de contact est également caractérisée en ce que la première couche de revêtement est formée d'un alliage d'argent-étain, la seconde couche de revêtement est formée d'argent ou d'un alliage principalement composé d'argent et la dureté de la première couche de revêtement est supérieure à la dureté de la seconde couche de revêtement. La première couche de revêtement présente une dureté Vickers de 250 à 400 et la seconde couche de revêtement une dureté Vickers de 80 à 200.
(JA) 【課題】可動接触端子に適用した場合、オンオフ操作を繰り返しても接触抵抗が増大しにくい耐久性に優れた接触端子構造を提供する。 【課題を解決するための手段】基体の表面に第一のメッキ層が形成され、該第一のメッキ層の表面に最外層として第二のメッキ層が形成されてなり、前記第一のメッキ層が銀錫合金からなり、前記第二のメッキ層が銀、または銀を主成分とする合金からなり、前記第一のメッキ層の硬度が前記第二のメッキ層の硬度より大きいことを特徴とする接触端子構造であり、また、前記第一のメッキ層のビッカース硬度が250~400であり、前記第二のメッキ層のビッカース硬度が80~200である接触端子構造である。
