Description

Technical Field

[0001] This utility model belongs to the field of shielding cover technology and relates to a high-frequency anti-interference shielding cover structure. Background Technology

[0002] Electronic products radiate electromagnetic waves when they are working, and are also subject to interference from external electromagnetic waves. Currently, due to factors such as the increasingly dense electromagnetic spectrum, the sharp increase in electromagnetic wave power density per unit volume, and the widespread use of high- and low-level devices or equipment, electromagnetic interference is becoming increasingly serious. Electromagnetic shielding is a method of confining electromagnetic waves to a certain area using shielding bodies such as shells, boxes, and plates made of metal. This method is one of the important means to solve the problem of electromagnetic interference. At present, many electronic devices cover their internal electronic components with electromagnetic shielding covers to protect them from electromagnetic interference. However, different electronic components have different heights, making it impossible to use electromagnetic shielding covers of the same specifications, which increases the required cost and fails to meet market demands, thus requiring improvement. Summary of the Invention

[0003] The purpose of this invention is to provide a high-frequency anti-interference shielding structure to solve the problems mentioned in the background art.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A high-frequency anti-interference shielding structure includes a circuit board, an electromagnetic shielding cover, a heightening pad, and side support frames. Side support frames are provided on both sides of the circuit board. An inner sliding groove is formed inside each side support frame, and an inner sliding seat is slidably disposed within the inner sliding groove. A lifting cavity is formed inside the inner sliding seat, and a support arm is movably disposed within the lifting cavity. The top of the support arm is connected to the electromagnetic shielding cover. The electromagnetic shielding cover is made of metal and has electromagnetic shielding effect. The electromagnetic shielding cover is a commercially available device known to those skilled in the art; we are only using it here without making any structural or functional improvements, and we will not elaborate further.

[0006] In the above-mentioned high-frequency anti-interference shield structure, an outer sliding groove is provided on the outer side of the side support frame, and an outer slider is slidably arranged inside the outer sliding groove, and the outer slider is connected to the end of the inner sliding seat.

[0007] In the above-mentioned high-frequency anti-interference shield structure, the outer side of the outer slider is threaded with a locking screw, and one end of the locking screw passes through the inner slide block and is pressed against the outer side of the support arm.

[0010] Compared with the prior art, the advantages of the high-frequency anti-interference shield structure of this utility model are as follows:

[0011] This application provides a side support frame on the side of the circuit board to support the electromagnetic shielding cover. Inside the side support frame is an inner slide block that slides inside an inner groove. By sliding the inner slide block, the position of the electromagnetic shielding cover can be adjusted. The height of the support arm inside the lifting cavity can also be adjusted, thereby adjusting the height of the electromagnetic shielding cover. In this way, targeted adjustments can be made to fit taller electronic components.
