The insulating layer 3 is composed of materials such as epoxy resin and is used to isolate the circuit board body 1 from other electrical equipment to prevent electrical short circuit. When the circuit board body 1 is used, the heat generated by the circuit board body 1 enters the heat dissipation slot 5 and is conducted out of the insulating layer 3 through the copper column 6. Since the copper columns 6 are independently arranged on the insulating layer 3, the air flow is more unobstructed, and at the same time, the driving motor 10 works, and the heat dissipation fan 11 rotates at high speed, thereby increasing the air flow speed around the copper column 6, making the heat flow away from the copper column 6 with the air flow, and further improving the heat dissipation effect of the circuit board body 1. The dust cover 12 is arranged on the connecting frame body 8, which can reduce the entry of dust and foreign matters, thereby reducing the cleaning frequency of the heat dissipation fan 11.

[0028] By corresponding the plug-in plate 16 and the installation groove 13, the insulating layer 3 is pressed downward, the plug-in plate 16 is slid in the installation groove 13, the plug-in plate 16 and the positioning block 19 are relatively slid along the slope angle due to the fact that the bottom of the plug-in plate 16 and the top of the positioning block 19 are provided with the slope surface, the positioning block 19 is moved inward in the installation groove 13, the adjusting rod 17 and the reset spring 18 are extruded and contracted, after moving downward by a certain depth, the top of the plug-in plate 16 is flush with the bottom of the positioning block 19, at this moment, the positioning block 19 returns to the original position under the elastic force of the reset spring 18 and limits the plug-in plate 16, thereby the position of the insulating layer 3 and the installation bottom plate 7 is fixed, the sliding block 20 is pulled to the two sides, the positioning block 19 is slid in the installation groove 13 and separated from the plug-in plate 16, the circuit board body 1 is pulled upward and can be taken off from the installation bottom plate 7, thereby the installation and dismounting of the circuit board body 1 are facilitated.

At the same time, the elastic force of the connecting spring 22 causes the fixing pressure plate 23 to move down and contact the circuit board body 1, thereby limiting the circuit board body 1 in the longitudinal direction. When the circuit board body 1 is working, the heat generated by it enters the heat dissipation groove 5 and is discharged from the insulating layer 3 through the copper pillar 6. At the same time, the drive motor 10 is working and the cooling fan 11 rotates at high speed, thereby accelerating the air flow around the copper pillar 6 and causing the heat to be removed from the copper pillar 6 with the air flow.
