Claims

[Scope of utility model registration request]

A center conductor whose periphery is covered with an insulating material, a mounting flange surrounding the center conductor, and an insulated insulating pipe and an insulated insulating pipe arranged above and below the mounting flange are integrated by an elastic member attached to the center conductor. In a bushing with a center clamp structure, the mounting flange is provided with a support fitting that supports the lower end surface of the aerial insulator tube, and the upper surface of this support member has a sloped portion outward from the center of the aerial insulator tube. formed,
A sloped portion having the same slope as the upper surface of the support fitting is formed on the lower end surface of the aerial insulator tube, and a sealing material is provided on the contact surface between the lower end surface of the aerial insulator tube and the upper surface of the support fitting. Bushing features.
