[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. The utility model discloses an anti-interference integrated circuit board. By arranging filter capacitors and common-mode inductors around the power input end of the integrated circuit board, when the integrated circuit is working, the filter capacitors and the power input end work together to eliminate the power signal interference formed on the power input end of the integrated circuit, thereby improving the working efficiency and anti-interference ability of the integrated circuit. And a magnetic isolation anti-interference cover is arranged on the outer periphery of the integrated circuit board. The magnetic isolation anti-interference cover covers the top surface of the circuit support cavity seat and wraps the integrated circuit board. Furthermore, during the working process of the main chip in the integrated circuit, due to the low heat dissipation efficiency, signal interference is formed.

This setting, through the common cooperation of the circuit board component and the anti-interference component, enables the integrated circuit board to have an anti-interference signal effect, thereby extending the service life and working efficiency of the circuit board.

[0015] 2. The utility model discloses an anti-interference integrated circuit board. After the integrated circuit board is used for a long time, maintenance and repair work needs to be carried out. At this time, the operator needs to detach the magnetic isolation anti-interference cover from one side of the circuit support cavity seat for subsequent maintenance work. The user can pull the pulling block in a direction away from the circuit support cavity seat, so that the pulling block drives the connecting plate and the L-shaped plate to move in a direction away from the clamping block. The two L-shaped plates drive the two first magnets to move in a direction away from the clamping block until the first magnets are magnetically separated from the second magnets, and the first magnets are completely pulled out from the cavity grooves in front of the clamping block. At this time, the two clamping blocks lose their fixation. Subsequently, the operator can pull up the magnetic isolation anti-interference cover, and the magnetic isolation anti-interference cover drives the two clamping blocks to be pulled out of the two clamping grooves, and then the magnetic isolation anti-interference cover is detached from the circuit support cavity seat, and the integrated circuit board is exposed to the external environment, facilitating the user to carry out maintenance work. This setting enables the device not only to make the integrated circuit board have an anti-interference signal effect by using the magnetic isolation anti-interference cover, but also the magnetic isolation anti-interference cover is convenient for the user to install and detach, thereby facilitating the operator to carry out maintenance and repair work on the circuit board and improving the practicability of the device.

[0031] In summary, the working principle of the device of the present utility model: The present utility model discloses an anti-interference integrated circuit board. In the present utility model, filter capacitors 12 and common-mode inductors 14 are arranged around the power input terminal 13 of the integrated circuit board. When the integrated circuit is working, under the joint action of the filter capacitor 12 and the power input terminal 13, the power input terminal 13 of the integrated circuit can eliminate the power signal interference formed thereon, thereby improving the working efficiency and anti-interference ability of the integrated circuit. And a magnetic isolation anti-interference cover 21 is arranged on the outer periphery of the integrated circuit board. The magnetic isolation anti-interference cover 21 covers the top surface of the circuit support cavity seat 11 and wraps the integrated circuit board. Furthermore, during the working process of the main chip 112 in the integrated circuit, signal interference is formed due to the low heat dissipation efficiency. The design of the magnetic isolation anti-interference cover 21 can be used to shield the signal interference, thereby improving the anti-interference ability of the integrated circuit board; when the integrated circuit board is put into use, the circuit board can be installed at a specified position by installing the circuit support cavity seat 11, and at the same time, space should be reserved for multiple heat sinks 16 at the bottom of the circuit support cavity seat 11 to allow air to flow around the multiple heat sinks 16. In order to enable the heat generated by the integrated circuit board to be dissipated quickly during operation, multiple heat dissipation hole cavities 15 are arranged on the circuit support cavity seat 11, and the multiple heat dissipation hole cavities 15 are located at the bottom of the lead frame 111, and a heat sink 16 is arranged at the lower end of each corresponding heat dissipation hole cavity 15. Through the heat dissipation channels formed by the heat dissipation hole cavities 15 for the group of heat sinks 16, the heat dissipated by the integrated circuit can be quickly dissipated to the surrounding environment by using the heat sinks 16, achieving the purpose of rapid heat dissipation, improving the heat dissipation efficiency, and reducing signal interference. This setting, through the joint cooperation of the circuit board assembly 1 and the anti-interference assembly 2, enables the integrated circuit board to have an anti-interference signal effect, thereby extending the service life and working efficiency of the circuit board;

[0032] After long-term use, the integrated circuit board needs to be maintained and repaired. At this time, the operator needs to detach the magnetic isolation and interference protection cover 21 from one side of the circuit support cavity base 11 to facilitate subsequent maintenance work. The user can pull the pulling block 24 in a direction away from the circuit support cavity base 11, so that the pulling block 24 drives the connecting plate 25 and the L-shaped plate 26 to move in a direction away from the clamping block 22. The two L-shaped plates 26 drive the two first magnets 261 to move in a direction away from the clamping block 22 until the first magnets 261 are magnetically separated from the second magnets 221, and the first magnets 261 are completely pulled out from the cavity grooves in front of the clamping blocks 22. At this time, the two clamping blocks 22 lose their fixation. Subsequently, the operator can pull up the magnetic isolation and interference protection cover 21, and the magnetic isolation and interference protection cover 21 drives the two clamping blocks 22 to be pulled out from the two card slots 23. Thus, the magnetic isolation and interference protection cover 21 is detached from the circuit support cavity base 11, and the integrated circuit board is exposed to the external environment, facilitating the user to carry out maintenance work. If the magnetic isolation and interference protection cover 21 needs to be reinstalled subsequently, cover the magnetic isolation and interference protection cover 21 back on the top surface of the circuit support cavity base 11, and make the two clamping blocks 22 correspondingly inserted into the two card slots 23. At the same time, the two L-shaped plates 26 are respectively corresponding to the two clamping blocks 22. The worker pushes the pulling block 24 towards the inside of the circuit support cavity base 11, so that the pulling block 24 drives the L-shaped plate 26 to move towards the clamping block 22 until the two first magnets 261 are inserted back into the cavity grooves in front of the two clamping blocks 22 again. The second magnet 221 is magnetically connected and fixed to the first magnet 261, and the two L-shaped plates 26 fix the two clamping blocks 22 and the magnetic isolation and interference protection cover 21 again, making the magnetic isolation and interference protection cover 21 firmly fixed on the top surface of the circuit support cavity base 11 and continuing to protect the integrated circuit board. This setting enables the device not only to make the integrated circuit board have an anti-interference signal effect by using the magnetic isolation and interference protection cover 21, but also the magnetic isolation and interference protection cover 21 is convenient for the user to install and detach, thereby facilitating the operator to carry out maintenance and repair work on the circuit board and improving the practicality of the device.

[0033] The above embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
