Description

Technical Field

[0001] The utility model relates to the technical field of electrical accessories, in particular to a switch pole structure. Background Art

[0002] Currently, many versions of semi-encapsulated environmentally friendly switches are available on the market. However, the injection molding of their pole products is inconvenient. They are generally core-pulled from six directions, which makes injection molding difficult and the mold production cost high. At the same time, during installation, the elastic parts are not properly fixed due to uneven force when they are squeezed into the cavity. The fence side of the existing pole products is equipped with a horizontal bar for installing screws. During installation, the flexible connection can only be assembled by passing through the horizontal bar, making it inconvenient to assemble the entire product. Utility Model Content

[0003] In view of the deficiencies in the existing technology, the present invention aims to provide a switch pole structure.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a switch pole structure, including a large bracket and a plurality of pole cavities arranged on the large bracket, wherein the pole cavity includes a fence and an assembly cavity.

[0005] Furthermore, the fence is arranged around the outer contour of the assembly cavity, and the inner contour of the fence is slightly larger than the outer contour of the assembly cavity.

[0006] Furthermore, the fence is provided with a first notch and a second notch, and the first notch and the second notch are symmetrical with respect to the axis of the assembly cavity.

[0007] Furthermore, the fence is provided with a U-shaped notch.

[0008] Furthermore, a plurality of mounting posts are provided between the assembly cavity and the fence, and each mounting post is provided with a hole.

[0009] Furthermore, a bottom cover is provided at the bottom end of the assembly cavity, and the bottom cover is provided with a through hole.

[0010] Furthermore, the large bracket and the pole cavity are integrally injection molded.

[0011] The beneficial effects of the utility model are as follows: the utility model reduces the difficulty of injection molding and the cost of mold production; the elastic member squeezed into the cavity is evenly stressed, the elastic member has a good fixing effect and is not easy to shift; the cross piece is removed, making the assembly of the whole machine convenient.

[0015] like Figure 1-Figure 3 As shown, a switch pole structure includes a large bracket 1 and a plurality of pole cavities 2 provided on the large bracket 1 , wherein the pole cavity 2 includes a fence 21 and an assembly cavity 22 .

[0016] In the above structure, the pole cavity 2 is used to fix the arc extinguishing chamber.

[0017] In this embodiment, the fence 21 is provided around the outer contour of the assembly cavity 22 , and the inner contour of the fence 21 is slightly larger than the outer contour of the assembly cavity 22 .

[0018] In the above structure, the elastic member is evenly squeezed into the assembly cavity 22 along the circumferential opening at one end of the assembly cavity 22. At this time, the elastic member is evenly stressed and is not easily displaced.

[0019] In this embodiment, the fence 21 is provided with a first notch 211 and a second notch 212 , and the first notch 211 and the second notch 212 are symmetrical with respect to the axis of the assembly cavity 22 .

[0020] In the above structure, no crossbars are provided at the first notch 211 and the second notch 212 of the fence, and the whole product is easy to assemble.

[0021] In this embodiment, the fence 21 is provided with a U-shaped notch 213 to facilitate parameter measurement.

[0022] In this embodiment, a plurality of mounting posts 23 are provided between the assembly cavity 22 and the fence 21 , and each mounting post 23 is provided with a hole 231 .

[0023] In the above structure, the holes 231 of the plurality of mounting posts 23 can be screwed in with screws.

[0024] In this embodiment, a bottom cover 221 is provided at the bottom end of the assembly cavity 22 , and the bottom cover 221 is provided with a through hole 2211 .

[0025] In the above structure, the bottom cover 221 is provided so that the arc extinguishing chamber can be reliably fixed in the pole cavity 2 to ensure the stability of the arc extinguishing chamber when opening and closing. The through hole 2211 is used for connecting the static end conductive parts of the arc extinguishing chamber.

[0026] In this embodiment, the large bracket 1 and the pole cavity 2 are integrally injection molded.

[0027] The utility model uses its own structural characteristics to enable the large bracket 1 and the pole cavity 2 to be integrally injection-molded by core pulling from four directions, thereby reducing the difficulty of injection molding and the cost of mold production.

[0028] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Without departing from the spirit and scope of the present invention, simple modifications and substitutions by those skilled in the art are within the scope of protection of the present invention.
