Claims

[Scope of utility model registration request]

(1) When a housing recess is provided on the opposing surface of the arc electrode,
In addition, a fitting recess is provided concentrically at the bottom of the accommodation recess, and a contact is accommodated in the accommodation recess, and a joint in which the contact is concentrically protruded from the contact back surface is fitted into the fitting recess. In a vacuum interrupter electrode that is fixed to the arc electrode by a brazing material interposed between the end of the joint and the bottom of the fitting recess, the outer diameter of the contact 5 is the same as that of the housing recess 3 of the arc electrode 2. An electrode for a vacuum interrupter characterized by being formed to have a relatively small diameter compared to the inner diameter.

(2) The vacuum interrupter electrode according to claim 1, wherein the length of the joint portion 5a of the contact 5 and the depth of the fitting recess 4 of the arc electrode 2 are approximately equal.

(3) The length of the joint portion 5a of the contact 5 is set relatively larger than the depth of the fitting recess 4 of the arc electrode 2. Vacuum interrupter electrode.

(4) The distance between the outer periphery of the contact 5 and the inner periphery of the housing recess 3 of the arc electrode 2 is 0.5 to 4 m. The electrode of the vacuum interrupter according to item 3.

(5) The vacuum interrupter according to claim 1, 2, 3, or 4 of the utility model registration claim, characterized in that the opening periphery of the housing recess 3 of the arc electrode 2 is formed in a rounded shape. electrode.

(6) The vacuum interrupter according to claim 1, 2, 3, 4, or 5 of the utility model registration claim, characterized in that the outer peripheral edge of the contact 5 is formed in a rounded shape. electrode.
