Description

Technical Field

[0001] The utility model relates to the technical field of electrical switches, in particular to an auxiliary module for controlling and protecting switches. Background Art

[0002] The auxiliary module of the existing control and protection switch generally includes a shell and various components (contact support, static contact piece, moving contact bridge, etc.) arranged in the shell. The shell of this auxiliary module is integrally formed. When installing, all the components need to be assembled and then inserted into the shell from the through hole at the bottom. This installation method is relatively cumbersome, and the components are easy to detach during the installation process, resulting in installation failure. Summary of the invention

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the utility model is to provide an auxiliary module of a control and protection switch which is easy to install.

[0004] To this end, the utility model is implemented by adopting the following technical solutions:

[0005] The auxiliary module of the control and protection switch comprises an auxiliary shell, wherein the auxiliary shell and the base are detachably connected, and the auxiliary shell comprises a detachably connected shell body and a cover plate.

[0006] Furthermore, a plurality of columns are provided in the shell, threaded holes are provided on the columns, through holes aligned with the threaded holes are provided on the cover plate, and screws threadedly connected to the threaded holes are passed through the through holes.

[0007] Furthermore, mounting plates are provided downwardly at the front and rear sides of the shell, buckle holes are provided on the mounting plates, and buckles that are buckled with the buckle holes are provided on the base.

[0008] After adopting the above technical solution, the auxiliary shell includes a detachably connected shell and a cover plate. The auxiliary shell is changed from an integrally formed structure to a detachable structure. During installation, each component is installed into the shell and then the cover plate is installed. The installation process is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0013] Referring to the above-mentioned drawings, the auxiliary module of the control and protection switch provided by the utility model includes an auxiliary shell 1, and the auxiliary shell 1 and the base 2 are detachably connected, and its characteristics are: the auxiliary shell 1 includes a shell 3 and a cover plate 4 that are detachably connected, a plurality of columns are arranged in the shell 3, threaded holes 5 are arranged on the columns, the cover plate 4 is provided with a through hole 6 aligned with the threaded hole 5, the through hole 6 is penetrated by a screw threadedly connected to the threaded hole 5, the front and rear sides of the shell 3 are downwardly provided with a mounting plate 7, a buckle hole 8 is arranged on the mounting plate 7, and a buckle 9 buckled with the buckle hole 8 is arranged on the base 2.

[0014] In this embodiment, the components are first installed into the shell 3, and then the cover plate 4 is covered, and the screws are screwed to fix the cover plate 4 and the shell 3. Finally, the auxiliary module is installed by connecting with the base 2 and the buckle 9 through the buckle hole 8. The installation process is simple and convenient, and the structure has good stability.

[0015] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
