AI Technical Summary
The coils of existing control and protection switches lack isolated support structures, leading to magnetic field coiling and affecting the accuracy and stability of electromagnet operation.
Multiple rows of inclined through holes are provided on the front and rear sides of the housing. The front and rear parts of each coil are inserted into the corresponding through holes to ensure coil positioning and prevent coil merging.
This improves the accuracy and stability of the electromagnet's moving iron core's movement and enhances the coil's positioning stability.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical switch technology, and specifically to a coil separation support structure for controlling and protecting switches. Background Technology
[0002] The coils of existing control and protection switches mostly consist of a housing and a coil frame inside the housing. Multiple turns of coil are wound on the coil frame. In this structure, the coils are not separated or have a supporting structure. When the coil is energized, the magnetic field can easily cause the coils to coil together. When the coils are coiled together, the magnetic force is insufficient, which leads to inaccurate and unstable operation of the moving iron core of the electromagnet. Summary of the Invention
[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a coil separation support structure for a control and protection switch that provides coil positioning.
[0004] Therefore, this utility model is implemented using the following technical solution:
[0005] A coil-separated support structure for a control and protection switch includes a housing and a coil frame disposed within the housing, wherein multiple turns of coil are wound on the coil frame. The characteristic feature is that multiple rows of through holes are provided on the front and rear sides of the housing, and the front and rear parts of each turn of the coil are inserted into the corresponding through holes.
[0006] Furthermore, the through hole is inclined.
[0007] After adopting the above technical solution, the front and rear parts of each coil are inserted into the corresponding through holes, so that the coil is positioned. After the coil is energized, there will be no phenomenon of coils merging, thus making the movement of the electromagnet's moving iron core more accurate and stable. Attached Figure Description
[0008] The present invention includes the following figures:
[0009] Figure 1 This is a three-dimensional structural diagram of the present invention.
[0010] Reference numerals: 1. Housing; 2. Coil; 3. Through hole. Detailed Implementation
[0011] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0012] Referring to the above figures, the coil separation support structure of the control and protection switch provided by this utility model includes a housing 1 and a coil frame disposed in the housing 1. Multiple turns of coil 2 are wound on the coil frame. The characteristic is that multiple rows of through holes 3 are provided on the front and rear sides of the housing 1. The front and rear parts of each turn of the coil 2 are inserted into the corresponding through holes 3. The through holes 3 are inclined.
[0013] In this embodiment, the front and rear parts of each coil 2 are inserted into the corresponding through hole 3 to position the coil 2. After the coil 2 is energized, there will be no coiling phenomenon, which makes the movement of the electromagnet's moving iron core more accurate and stable. In addition, the through hole 3 is tilted in the same direction as the oblique winding of the coil 2, which increases the contact area between the coil 2 and the through hole 3, further improving the positioning stability of the coil 2.
[0014] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
