Embodiment Construction
[0026] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0027] Specific embodiments of the contact assembly of the present invention, such as Figure 1 to Figure 2 As shown, the contact assembly is a moving contact assembly in a disconnector, which includes a moving main contact 1 whose axis extends left and right. It is made of 6063 aluminum, and the outer surface is plated with silver to reduce the contact resistance coefficient and ensure The effective electrical contact between the moving main contact 1 and the main conductive circuit, the moving main contact 1 is provided with a through hole extending along the axis, and an inner flange is arranged in the through hole near the right end, and a screw is passed on the inner flange 2 is connected with a copper contact seat 3 (that is, a conductive seat). The copper contact seat 3 is a cylindrical structure with an outer flange at one end. The copper contact...
