[0026] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] like Figure 1-Figure 4 A sealed pole for a vacuum circuit breaker shown in the figure includes an insulating shell 10 and a positioning boss 20 movably arranged on the back of the insulating shell 10. The back of the insulating shell 10 is also provided with a groove for the positioning boss 20 to slide. A first positioning structure 40 is provided in the groove 30 for facilitating the positioning boss 20 to limit the position. The positioning boss 20 is provided with a second positioning structure 50 that cooperates with the first positioning structure 40.

[0029] The first positioning structure 40 is a strong magnetic strip embedded in the two inner sides of the groove 30, and the positioning boss 20 is also provided with a rotatable column 60 and a cavity 70 for accommodating the column 60. The two sides of the column 60 are provided with magnetic blocks that cooperate with the strong magnetic strip for adsorption, wherein the left and right sides of the cavity 70 are also provided with through holes 90, and the two sides of the column 60 are provided with protrusions 80 that cooperate with the through holes 90 for positioning and installation. That is, the positioning boss 20 is positioned by the mutual attraction between the magnetic block and the strong magnetic strip, and when the magnetic block rotates to the top and bottom of the column 60, the positioning boss 20 and the groove are released, that is, the protrusion 80 and the two magnetic blocks are on the same side and the protrusion 80 is a hemispherical structure.

[0030] The end of the column 60 is also provided with a stopper block, and the cavity 70 is provided with a slot that cooperates with the stopper block to limit and fix the column 60. When the column 60 is rotated to the locked position or the limit is released, the stopper block can be inserted into the slot to limit the rotation of the column 60, that is, to prevent the column 60 from moving due to the attraction of magnetic force. Specifically, the slot is a slot body with a polygonal structure, and the shape of the stopper block matches the polygon, such as a triangle, a quadrilateral, a regular hexagon, etc.

[0031] It should be noted that the positioning boss 20 is only provided to facilitate the positioning of the sealed pole and the back plate of the vacuum circuit breaker, and does not need to have a certain structural strength, as long as it is stable before the bolt assembly. The purpose of this application is to increase the adaptation rate between the positioning boss 20 and its positioning groove due to process errors or structural design problems, that is, the scope of application is wider, and the position of the boss can be adjusted to adapt to the positioning groove within this range, thereby further improving the consistency rate.

[0032] The magnetic blocks are embedded on both sides of the column 60. There are two magnetic blocks, and the two magnetic blocks are symmetrically arranged. The material of the positioning boss 20 is the same as that of the insulating shell 10, both of which are epoxy resin. The column 60 is embedded in the cavity 70, and its end face is flush with the outer surface of the positioning boss 20. A cross-shaped groove is also provided on its end face so that the user can rotate the column 60 with a tool such as a screwdriver.

[0033] Example 2

[0034] like Figure 5 , Figure 6 As shown, the difference from Example 1 is that the first positioning structure 40 is a plurality of longitudinally distributed circular grooves, while the second positioning structure 50 is a hemispherical protrusion, which is an integrated structure with the positioning boss 20. The circular grooves are arranged longitudinally and linearly, so that the positioning boss 20 can be adjusted in multiple levels.

[0035] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary personnel in the field to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents of the present invention for protection have been fully recorded in the claims.
