Description

Technical Field

[0001] This utility model relates to the field of electromagnetic shielding technology, specifically to an electromagnetic shielding structure for a power switch. Background Technology

[0002] During operation, power switches generate significant electromagnetic radiation due to sudden current changes and high-frequency switching. This radiation can interfere with surrounding electronic equipment, affecting their normal operation. For example, in a system containing multiple electronic devices, if the power switch is not electromagnetically shielded, its electromagnetic radiation may interfere with the signal transmission of other devices, leading to data errors or equipment malfunctions. Typically, a metal shield is installed on the outside of the power switch for electromagnetic shielding.

[0003] However, when using the power switch, the cover still needs to be opened for control. When the cover is opened, the power switch loses its electromagnetic shielding function. Therefore, an electromagnetic shielding structure for the power switch is proposed. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a technical solution: an electromagnetic shielding structure for a power switch. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 3 ,include:

[0026] The outer casing 1 has a switch 2 at its front end and a metal plate 3 outside the switch 2.

[0027] A metal outer ring shell 4 is disposed at the front end outside the metal plate 3. A metal round cover 5 is disposed inside the front end of the metal outer ring shell 4, and the metal round cover 5 is movably connected to the metal outer ring shell 4. An inner slide rod 13 is disposed on one side inside the metal round cover 5, and a cylinder 14 is slidably disposed outside the inner slide rod 13.

[0028] The limiting bolt 15 is located inside the cylinder 14, and the limiting bolt 15 is connected to the cylinder 14 by a threaded connection;

[0029] The identification sticker 6 is affixed to the outside of the metal round cover 5.

[0030] Please see Figure 2 and Figure 3 The metal plate 3 is connected to the outer shell 1 by screws, and the metal outer ring shell 4 is welded to the metal plate 3.

[0031] Please see Figure 2 and Figure 3 The metal round cover 5 has a washer 9 inside, and the washer 9 is rotatably connected to the metal round cover 5.

[0032] Please see Figure 2 and Figure 3 Telescopic rods 11 are provided on both the upper and lower sides inside the washer 9. A metal inner ring shell 12 is provided at the end of the telescopic rod 11 away from the washer 9. The telescopic rod 11 serves to limit the movement of the return spring 10. The metal inner ring shell 12 is used to improve the electromagnetic shielding function of the connection between the metal round cover 5 and the metal outer ring shell 4.

[0033] Please see Figure 2 and Figure 3 The telescopic rod 11 is provided with a return spring 10 on its outside, and the two ends of the return spring 10 are connected to the metal inner ring shell 12 and the washer 9. The return spring 10 enables the metal round cover 5 to have automatic reset property.

[0034] Please see Figure 2 and Figure 3 The outer edge of the metal round cover 5 is provided with anti-slip ridges 7, and the upper and lower sides of the metal round cover 5 are provided with levers 8. The anti-slip ridges 7 improve the anti-slip performance of the metal round cover 5, and the levers 8 are used to rotate the metal round cover 5.

[0035] This solution involves: loosening the limiting bolt 15, then adjusting the position of the cylinder 14 by sliding it outside the inner slide rod 13 according to the position of the switch 2, so that the position of the cylinder 14 corresponds to that of the switch 2. Next, tighten the limiting bolt 15 and attach the identification sticker 6 to the outside of the metal cover 5 at the position corresponding to the cylinder 14. Then, install the metal plate 3 on the outside of the outer casing 1. When the switch 2 needs to be used, press the metal cover 5. The metal cover 5 will be forced and move towards the switch 2, causing the cylinder 14 to move and touch the switch 2. One end of the switch 2 will be forced, and the other end will tilt upwards. When the tilted part of the switch 2 needs to be pressed, rotate the metal cover 5 using the toggle plate 8 and the anti-slip ridge 7. Use the identification sticker 6 to determine the rotation angle of the cylinder 14. Rotate the cylinder 14 to the tilted end of the switch 2, and push the metal cover 5 to touch the tilted end of the switch 2.
