Circuit boards can be called printed circuit boards or printed circuit boards. FPC circuit boards are also called flexible circuit boards. Flexible circuit boards are made of polyimide or polyester film as substrates. They are highly reliable and extremely flexible printed circuit boards with high wiring density, light weight, thin thickness, and good bending properties. The birth and development of rigid-flexible boards and PCBs gave birth to a new product, rigid-flexible boards. Therefore, rigid-flexible boards are flexible circuit boards and rigid circuit boards. After lamination and other processes, they are combined according to relevant process requirements to form circuit boards with FPC characteristics and PCB characteristics.

[0003] However, it still has some disadvantages. For example, the circuit board is usually in direct contact with the equipment during use. Because the material of the circuit board is relatively fragile, if it is not protected during installation or maintenance, the surface of the circuit board will be broken, rendering the circuit board unusable, thereby increasing the cost of using the circuit board. In addition, dust will accumulate on the surface of the circuit board under long-term operation. If it is not cleaned regularly, a large amount of dust will accumulate on the surface of the circuit board, which is not conducive to the use of the circuit board. In addition, the circuit board will have the problem of overheating after long-term operation. Once the temperature is too high, the circuit board will be damaged.

[0023] In this embodiment, Figure 4 As shown, a heat sink 18 is movably connected to the outer surface of the lower end of the protective outer cover 1, a fixing frame 19 is fixedly connected to the outer surface of the lower end of the protective outer cover 1, a placement groove 20 is provided on the outer surface of the upper end of the protective outer cover 1, a positioning column 21 is fixedly connected to the outer surface of the upper end of the placement groove 20, a ventilation groove 22 is provided on the left outer surface of the protective outer cover 1, and a shielding film 23 is movably connected to the outer surface of the upper end of the protective outer cover 1.

[0024] Working principle:

[0025] In the present device, the upper end of the circuit board 2 is provided with a relay 3, a main control chip 4, a flat cable 5, a diode 6 and a resistor 7, which is the upper basic setting of the circuit board 2, and the circuit board 2 is located inside the protective cover 1, and a positioning column 21 is provided inside the protective cover 1.

A heat sink 18 and a venting groove 22 are respectively provided at the lower end and around the protective cover 1, and a shielding film 23 is provided at the upper end of the protective cover 1. The protective cover 1 is connected to the device through a fixing frame 19.
