Although these shells can provide protection to a certain extent, they still have shortcomings. Some shells have complex designs, which not only increase the difficulty of installation, but also make subsequent maintenance and replacement inconvenient. Circuit boards generate a lot of heat during operation. If the shell design is not reasonable, it is easy to cause heat accumulation, which will affect the performance of the circuit board and even cause failure.

[0026] Example 1
[0027] like Figure 1-4 As shown, this is the first embodiment of the present invention. This embodiment provides a detachable protective shell for protecting circuit boards, including a base plate 1 and a top cover 2. The base plate 1 has two base plate positioning holes 4 at its center, and circuit board mounting holes 3 are provided at the four corners of the base plate 1. The top cover 2 has top cover mounting holes 6 at the four corners of the top and bottom.
[0028] like Figure 1-4 As shown, there are four sets of screws and nuts, which are installed on the circuit board mounting holes 3 at the four corners, the circuit board mounting holes 3 and the top cover mounting holes 6, for a total of eight mounting holes. The internal circuit board is firmly fixed by the screws, and the four top cover mounting holes 6 are connected and fixed with the screws. The base plate 1 has two base plate positioning holes 4 in the middle. The screws can be installed on the outside of the base plate 1 by passing them through the base plate positioning holes 4. The clips are made of a metal or plastic material with a certain degree of elasticity to ensure that they can be firmly fastened to the slide rail. Then the slide rail is fixed in the corresponding required installation position, which is convenient for disassembly. Nails can also be used to fix it in the required installation position directly through the base plate positioning holes 4. The base plate 1 and the top cover 2 are made of high-strength engineering plastic particles and are formed by injection molding to ensure the strength of the shell.
[0029] Example 2
[0030] Reference Figure 1 , 2 3 and 4 represent the second embodiment of this utility model, which is based on the previous embodiment.
[0031] In this embodiment, the upper cover 2 has a groove 7 in the middle.
[0032] A base plate groove 5 is provided in the middle of the base plate 1.
[0033] like Figure 1 , 2As shown in Figure 3, the base plate groove 5 and the top cover groove 7 can effectively accommodate the circuit board and the copper pillar. The top cover groove 7 fixes the top cover 2 through the top cover mounting holes 6 at the four corners of the top cover 2. The base plate groove 5 fixes the circuit board and the top cover 2 through the circuit board mounting holes 3 at the top and bottom corners of the base plate 1 and the top cover mounting holes 6 at the top and bottom corners of the top cover 2.
[0034] Example 3
[0035] Reference Figure 1-3 This is the third embodiment of the present invention, which is based on the first two embodiments.
[0036] In this embodiment, the size of the base plate 1 can be adjusted according to the size of the circuit board.
[0037] The size of the groove 7 on the top cover can be set according to the size of the circuit board components.
[0038] The size of the top cover 2 is smaller than the size of the bottom plate 1.
[0039] like Figure 1-3 As shown, the length and width of the top cover 2 are set according to the size of the circuit board to facilitate subsequent wiring and debugging of the circuit board.

[0042] In this embodiment,
[0043] Both the back of the base plate 1 and the top cover 2 are coated with fire-retardant paint to improve fire resistance.
[0044] like Figure 5-6 As shown, the fire-retardant coating is an intumescent fire-retardant coating with a thickness of ≤3mm. The intumescent fire-retardant coating will expand and foam at high temperatures to form a fire-resistant and heat-insulating protective layer, improve the fire resistance of the protective shell, slow down the spread of flames, and stop combustion in a short time.
[0045] During use, the dimensions of the four circuit board mounting holes 3 on the base plate 1 are consistent with the diameter of the positioning holes on the circuit board, and the positioning holes on the circuit board are aligned with the four corner circuit board mounting holes 3 on the base plate with an error of less than 0.1mm, ensuring that the circuit board can be stably fixed on the base plate 1. Screws, nuts, single-through copper pillars, and double-through copper pillars are used to fix the circuit board through the circuit board mounting holes 3.
