Embodiment Construction

[0011] Embodiment 1 of the assembly structure of the insulator and the outer flange of the present invention, such as Figure 1-4 Shown: The assembly structure of the insulator and the outer flange, including a concentric disc-shaped insulator 1 and a circular outer flange 2, the outer flange 2 is set on the periphery of the insulator 1, and the inner periphery of the outer flange 2 There is a gap between the outer surface of the outer flange 2 and the outer peripheral surface of the insulator 1, and there are four flanges evenly distributed along the circumferential direction between the inner peripheral surface of the outer flange 2 and the outer peripheral surface of the insulator 1, which are used to provide radial The pressing force is to make the insulator 1 tightly fix the leaf spring 3 located in the center of the outer flange 2. The leaf spring 3 is a bow-shaped structure. The leaf spring 3 has a convex part and two supporting parts that are respectively matched with t...

Abstract

The invention relates to an assembly structure of an insulator and an external flange. The assembly structure comprises the insulator and the external flange, wherein the external flange is mounted at the periphery of the insulator in a sleeving manner; at least three plate springs which are uniformly distributed in a circumferential direction and used for providing radial pressing forces for the external circumferential surface of the insulator to allow the insulator to be fastened and located in the center of the external flange are arranged between the internal circumferential surface of the external flange and the external circumferential surface of the insulator in a fastening manner; the plate springs are in arched structures; each plate spring is provided with a bulge and two supporting parts which are matched with the insulator and the external flange in a supporting manner; clamping grooves used for locating and clamping the plate springs are formed in the internal circumferential surface of the external flange or the external circumferential surface of the insulator; each clamping groove is provided with two groove walls which are oppositely arranged and circumferentially or axially matched with the two supporting parts in a blocking manner; and the clamping grooves are provided with groove bottoms radially matched with the supporting parts in a supporting manner. The assembly structure has the advantages of easy, simple and reliable assembly and simple assembly structure; the working efficiency is improved; and the reliability of the structure is improved.

Description

technical field [0001] The invention relates to an assembly structure of an insulator and an outer flange. Background technique [0002] The assembly structure of the insulator and the outer flange plays a vital role in the reliable operation of the gas-insulated metal-enclosed switchgear. In the prior art, the insulator has a disc-shaped structure, and the outer flange has an annular structure. There is an annular gap between the outer peripheral surface of the insulator and the inner peripheral surface of the outer flange, and the gap is equipped with uniformly distributed along the circumferential direction. Three springs, the springs extend in the radial direction, and the insulator is fixed at the center of the outer flange under the compression force of the springs. However, when the insulator is assembled with the outer flange, at least three people are required to cooperate to assemble the three springs synchronously. It is difficult to assemble into the above-menti...
