Abstract:
In case of using multi-contacts or flat braided wires for constituting a current carrying structure of a movable part in a vacuum relay, problems tend to appear, which are enlargement of a control mechanism, complication, increased operation force and the like. The vacuum relay 1 includes an insulating cylinder 2, a first relay connecting portion 4 that is connected to one open end of the insulating cylinder 2 and has on its inner surface a first contact 3, a second relay connecting portion 5 that is arranged in the insulating cylinder 2 to face the first relay connecting portion 4, a movable member 7 that is movably arranged between the first and second relay connecting portions 4 and 5 and has a second contact that is brought into contact with the first contact when the movable member is moved toward the first relay connecting portion, and a control mechanism 8 that moves the movable member 7 in both directions to establish and break the contact between the two contacts. Between the movable member 7 and the second relay connecting portion 5, there is provided a bellows 11 through which the movable member 7 and the second relay connecting portion 5 are electrically connected.
