Claims

[Scope of utility model registration request]

(1) A joint 14.22 is provided on at least one side of the main body 12.20 of the bushing 5.6 formed by integrally forming two bottomed cylinders back to back, and the connecting conductor 7 or fixed contact 10 is connected to each terminal. The portions 7a and lea are embedded and fixed in the bottom portion 1-6° 24 along the axis line so as to protrude outward from the main body 12.20, and the joint portions 14° and 22 are provided with a cylindrical body or a bottomed cylinder. A bushing characterized in that it is formed by connecting an auxiliary insulator 15.23 consisting of a body.

(2) The bushing according to claim 1, wherein the joint portion 14.22 consists of a groove 13 formed in the end face of the bushing body 12.20.

(3) A flange 17.17 in which the joint portion 14.22 protrudes near one end of the main insulator 12.20 and the auxiliary insulator 15.23.
Bushing 1 (4) auxiliary insulator 15.23 according to claim 1 of the utility model registration claim, characterized in that it consists of:
The bushing according to claim 1, characterized in that the bushing is made of a cylinder with a bottom, and has a through hole 19 in the bottom thereof through which the bus bar 8 or the conductor 9 can pass.
