DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0028] The present embodiment provides a technical solution: the present solution discloses a moving contact wire row fixing structure, comprising a front base 1, a rear bottom plate 2, a moving contact 3, a moving contact wire row 4 and a fixing plate, wherein the rear bottom plate 2 is mounted on the front base 1 using screws 12 to form an internal space, the moving contact 3 is mounted in the internal space between the front base 1 and the rear bottom plate 2, the moving contact wire row 4 is mounted on the moving contact 3 and extends from the wire hole opened on the rear bottom plate 2, the fixing plate is L-shaped including a flat plate and a side plate, the fixing plate is fixedly mounted on the moving contact wire row 4 using a flat plate, the moving contact 3 is fixed in the front base 1 via a fixing plate 6, and the fixing plate is fixed to the inner side of the rear bottom plate 2 using a side plate.

[0029] The fixing plate in this embodiment includes an upper fixing plate 5 and a lower fixing plate 6. The upper fixing plate 5 and the lower fixing plate 6 are fixedly mounted on the moving contact outlet row 4 from the top and bottom using a bottom plate and a top plate respectively. The moving contact 3, the moving contact outlet row 4, the upper fixing plate 5, the lower fixing plate 6 and related fasteners together constitute a moving contact assembly 9. The moving contact 3 is fixed in the front base 1 through the lower fixing plate 6. The upper fixing plate 5 and the lower fixing plate 6 are fixed on the inner side of the rear bottom plate 2 using side plates.

[0030] This embodiment is a more reliable fixing method, and only the lower fixing plate 6 may be used.

[0031] In this embodiment, the side plate of the lower fixing plate 6 is provided with screw notches for fixing to the front base 1, and screw holes may also be provided, and screws 10 are used to fix the moving contact 3.

[0032] The side plates of the upper fixing plate 5 and the lower fixing plate 6 are provided with screw holes for fixing to the rear bottom plate 2, and nuts 7 are welded or riveted on the back of the screw holes. There are two screw holes for fixing to the rear bottom plate 2. The upper fixing plate 5 and the lower fixing plate 6 are fixed to the rear bottom plate 2 by passing through the screw holes at corresponding positions on the rear bottom plate 2 with screws 11, thereby firmly fixing the moving contact 3 to the rear bottom plate 2.

[0033] For the positioning of the fixed plate and the moving contact wire row 4, in this embodiment, the bottom plate of the upper fixed plate 5 and the top plate of the lower fixed plate 6 are provided with two circular positioning steps 8 downward, and the moving contact wire row 4 is provided with moving contact wire row positioning holes 41 at positions corresponding to the positioning steps 8 on the upper and lower surfaces. The moving contact wire row positioning holes 41 are vertical through holes, and blind holes can also be used, as long as the depth of the blind holes is greater than the height of the positioning steps 8. However, this processing method is not as convenient as the fixing method of this embodiment.

[0034] For fixing the fixing plate and the moving contact wire row 4, two screw holes for fixing to the moving contact wire row 4 are opened on the bottom plate of the upper fixing plate 5 and the top plate of the lower fixing plate 6, and nuts 7 are welded or riveted on the back of the screw holes. In this embodiment, screws 13 are used to fix the upper fixing plate 5, the moving contact wire row 4 and the lower fixing plate 6 together. Since the screws 13 are fixed from the top to the bottom in this embodiment, the nuts 7 of the upper fixing plate 5 can be omitted. Riveting can also be used to fix the moving contact wire row 4 and the upper and lower fixing plates. When riveting, the riveting shaft is used instead of the screws, and the two nuts 7 on the fixing plate can be omitted. When only the lower fixing plate 6 is used for fixing, the screw holes of the moving contact wire row 4 can be tapped or fixed by riveting.

[0035] During assembly of this embodiment, the positioning steps on the upper fixing plate 5 and the lower fixing plate 6 are first docked with the positioning holes 41 of the moving contact outlet row, and then fastened with screws 13 to assemble the upper fixing plate 5 and the lower fixing plate 6 with the moving contact outlet row 4, and then the moving contact assembly 9 is installed into the front base 1, and the moving contact 3 is fixed by screws 10 passing through the screw notches of the lower fixing plate 6, and then the rear bottom plate 2 is assembled with the front base 1 and fixed with screws 3 12, and finally, screws 11 are passed through the rear bottom plate 2 and fixed in the nuts 7 of the upper fixing plate 5 and the lower fixing plate 6 to firmly fix the moving contact 3 to the rear bottom plate 2.
