Claims

[Scope of utility model registration request]

(1) A pair of lead rods 15 that airtightly penetrate the vacuum container 10, are arranged facing each other, and are relatively movable toward and away from each other.
．． 17 at the inner end of each electrode 15a. 17a, the fixed terminal conductor 3 is connected to the outer end of one of the pair of lead rods 17 in an intersecting direction, and the lead rod 17 is connected to a rod-shaped central conductor 171. and a pipe-shaped reinforcement body 1 that integrally surrounds this.
72, a flange 173 is fixed to the outer end of the reinforcing body 172, and a current collector 5 is fixed to the outer end of the center conductor 171 that passes through the reinforcing body 172 and the flange 173. A vacuum interrupter characterized in that one surface of the current collector 5 is brought into contact with a flange 173, and the other surface is brought into contact with the fixed terminal conductor 3.

(2) The current collector 5 has a through hole 51 in the center, and the through hole 51
The vacuum interrupter according to claim 1, which is a utility model, wherein a center conductor 171 is inserted and fixedly integrated into the vacuum interrupter.

(3) Practical use characterized in that the current collector 5 is fixed to the end face of the center conductor 171 and is provided with a circular notch 53 larger than the diameter of the center conductor 171 on at least one side of the current collector 5. A vacuum interrupter according to claim 1 of the patent registration claim.
