[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0023] Reference Figure 1-5 As shown, an inductor with an anti-interference structure includes a first electromagnetic shielding cover 1, a plurality of first heat sinks 2 are fixedly installed on the outer surface of the first electromagnetic shielding cover 1, a second electromagnetic shielding cover 3 is threadedly connected to the upper end of the first electromagnetic shielding cover 1, and a plurality of second heat sinks 4 are fixedly installed on the outer surface of the second electromagnetic shielding cover 3. The first heat sink 2 and the second heat sink 4 can dissipate the heat generated by the inductor 8 working for a long time. By expanding the surface area of ​​the first heat sink 2 and the second heat sink 4, a larger heat dissipation surface can be provided, thereby accelerating the heat dissipation and heat dissipation, and reducing the inductor 8. The temperature can improve its working reliability and stability and extend its service life. A connecting plate 5 is arranged on the upper side of the first electromagnetic shielding cover 1. A circular opening 6 is penetrated on the upper side of the connecting plate 5. A ventilation plate 7 is arranged inside the circular opening 6. A fixing component 9 is arranged on the upper side of the connecting plate 5. The fixing component 9 includes two mounting plates 901. The bottom ends of the two mounting plates 901 are respectively fixedly mounted on the left and right ends of the upper side of the connecting plate 5. Two rectangular openings 902 are penetrated on the outer sides of the two mounting plates 901. The interiors of the two rectangular openings 902 are slidably connected with sliding blocks 903.

[0024] Reference Figure 3-5 As shown, a handle 904 is fixedly connected to the outer side of the sliding block 903. The handle 904 is used to slide the two sliding blocks 903 in the rectangular opening 902, and the compression spring 905 can drive the fixing plate 906 to fix the inductor. The inner sides of the two sliding blocks 903 are fixedly provided with a fixing plate 906. An inductor 8 is arranged between the two fixing plates 906. The part where the fixing plate 906 abuts against the inductor 8 is arc-shaped, which is convenient for fixing the inductor 8. Two sets of compression springs 906 are fixedly arranged on the inner sides of the two mounting plates 901 and the upper and lower ends of the sliding blocks 903. 5. One end of the compression spring 905 away from the inductor 8 is fixedly arranged on the inner side of the mounting plate 901, and the other end of the compression spring 905 is fixedly arranged on the outer side of the fixing plate 906. A cooling fan 10 is fixedly installed on the inner bottom end of the first electromagnetic shielding cover 1. When the first heat sink 2 and the second heat sink 4 are dissipating heat, the cooling fan 10 is started for air cooling. The heat is conducted and diffused through the contact between the first heat sink 2 and the second heat sink 4, and the airflow of the cooling fan 10 is pushed to accelerate the heat dissipation. The inner diameter of the first electromagnetic shielding cover 1 is smaller than the diameter of the circular opening 6.

[0025] Working principle and use process of the utility model: When in use, the second electromagnetic shielding cover 3 can be removed from the first electromagnetic shielding cover 1 by rotating it. The first electromagnetic shielding cover 1 and the second electromagnetic shielding cover 3 form an electromagnetic shielding structure, which can effectively isolate external electromagnetic radiation and interference. By pulling the handles 904 on the left and right sides, the handles 904 drive the sliding block 903 to slide in the rectangular opening 902, and the compression spring 905 installed on the inner side of the sliding block 903 drives the fixing plate 906 to move. When it moves to a suitable position, the inductor 8 is placed on the connecting plate 5 , and after placing it in a suitable position, release the handle 904. Due to the elastic deformation of the compression spring 905, the fixing plate 906 fixes the inductor 8 on the upper side of the connecting plate 5. Fixing the inductor 8 can ensure the position and connection stability of the inductor 8 in the circuit. The first heat sink 2 installed on the outer surface of the first electromagnetic shielding cover 1 and the second heat sink 4 installed on the outer surface of the second electromagnetic shielding cover 3 can cooperate with the cooling fan 10 to dissipate the heat of the inductor 8. Proper heat dissipation can reduce the impact of temperature changes and thermal stress on circuits and electronic components, and improve the reliability of the system.
