SEALED RELAY
Document Type and Number:
WIPO Patent Application WO/2014/196426
Kind Code:
A1
Abstract:
When multi-contacts, flat braids, or the like, are used for the electrically conductive structure of a part on the moving side of a vacuum relay, there are problems such as increase in the size and complexity of the operation mechanism, and increase in the operating force. A vacuum relay (1) is provided with an insulating cylinder (2), a first relay contact part (4) mounted on one end of the insulating cylinder (2) and having a first contact (3) on the internal side, a second relay contact part (5) disposed inside the insulating cylinder (2) and facing the first relay contact part (4), a moving member (7) movably disposed between the first relay contact part (4) and the second relay contact part (5) and having a second contact (6) contacting the first contact (3) when moved toward the side of the first relay contact part, and an operation mechanism (8) for moving the moving member (7) in the contact open-close directions. Bellows (11) are provided between the moving member (7) and the second relay contact part (5) for electrically connecting the moving member (7) and the second relay contact part (5).
