[0014] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0015] Example: The accompanying drawings illustrate a specific embodiment of a power module applicable to multiple circuit boards according to this utility model. It mainly includes a sealing plate 1, a circuit board 2, a power module housing 3, an adapter plate I 4, a water baffle plate I 5, an adapter plate II 6, and a water baffle plate II 7. The circuit board 2 includes an upper single board 201 and a lower single board 202, as shown in the attached drawings. Figure 2 As shown.

[0016] For specific installation instructions, please refer to... Figure 3 , Figure 4 The upper panel 201 is detachably mounted on the adapter plate I4. The back of the upper panel 201 has several positioning tubes 201a, each with a hollow interior and communicating with the other side of the upper panel 201. The adapter plate I4 has several positioning posts 4a that correspond to and are inserted into each positioning tube 201a. Each positioning post 4a has an internal thread. The positioning post 4a is inserted into one end of the positioning tube 201a and secured by a circuit board locking bolt I8. The circuit board locking bolt I8 passes through the other end of the positioning tube 201a and engages with the positioning post 4a through a threaded connection, thus locking and securing the upper panel 201.

[0017] The assembled adapter plate I4 and the upper single plate 201 are then placed together inside the sealing plate 1. The adapter plate I4 is provided with several positioning holes 4b, and the sealing plate 1 is provided with several positioning parts 1a corresponding to each positioning hole 4b. The positioning parts 1a can pass through the positioning holes 4b for positioning and installation, thereby realizing the positioning and installation of the adapter plate I4 and the upper single plate 201.

[0018] A water-blocking plate I5 is placed at one end of an adapter plate I4, and the water-blocking plate I5 and the adapter plate I4 are fixed together to the sealing plate 1 by adapter plate locking bolts I9. Specifically, the water-blocking plate I5 has several equally spaced locking bolt holes I9a along its length, the adapter plate I4 has several equally spaced locking bolt holes I9a at both ends, and the sealing plate 1 has several equally spaced locking bolt holes I9a at both ends. By passing multiple adapter plate locking bolts I9 through the locking bolt holes I9a on the water-blocking plate I5 and the corresponding adapter plate I4 and sealing plate 1 at one end, the water-blocking plate I5 and the adapter plate I4 can be fixed together to the sealing plate 1. Then, by passing multiple adapter plate locking bolts I9 through the locking bolt holes I9a on the other end of the adapter plate I4 and the sealing plate 1, the adapter plate I4 can be completely fixed to the sealing plate 1.

[0019] When assembling the entire sealing plate assembly, first fix the upper single plate 201 to the adapter plate I4 with the circuit board locking bolt I8, then position the assembled assembly on the sealing plate 1, place the water baffle I5 at one end of the adapter plate I4, and use the adapter plate locking bolt I9 to fix the assembly (including the upper single plate 201 and the adapter plate I4) and the water baffle I5 together on the sealing plate 1. The circuit board 2 is then installed on one side.

[0020] Reference Figures 5 to 7 The lower panel 202 is detachably mounted on the adapter plate II 6. The back of the lower panel 202 has several positioning connecting tubes 202a, each with internal threads. The adapter plate II 6 has several positioning connecting holes 6a corresponding to each positioning connecting tube 202a. The positioning connecting tube 202a is positioned on one side of the positioning connecting hole 6a and fixed by a circuit board locking bolt II 10. The circuit board locking bolt II 10 passes through the positioning connecting hole 6a from the other side and engages with the positioning connecting tube 202a through a threaded locking connection, thereby achieving the locking and fixing of the lower panel 202.

[0021] The assembled adapter plate II6 and the lower single plate 202 are then placed together on the bottom plate inside the power module housing 3. A water baffle II7 is placed at one end of the adapter plate II6, and is located on the same side as the water baffle I5.

Specifically, the water baffle II7 has several equally spaced locking bolt holes II11a along its length, the adapter plate II6 has several equally spaced locking bolt holes II11a at both ends, and the bottom plate of the power module housing 3 has several equally spaced locking bolt holes II11a at both ends. By using multiple adapter plate bolts II11 to pass through the water baffle II7 and the corresponding adapter plate II6 and the locking bolt holes II11a on the power module housing 3, the water baffle II7 and the adapter plate II6 can be fixed together on the bottom plate of the power module housing 3. Then, by using multiple adapter plate bolts II11 to pass through the other adapter plate II6 and the locking bolt holes II11a on the power module housing 3, the adapter plate II6 can be completely fixed inside the power module housing 3.

[0022] The installation steps on the other side of circuit board 2 are as follows: First, fix the lower single board 202 to the adapter plate 26 with circuit board locking bolt II10. After installation, place the assembled assembly inside the power module housing 3, place the water baffle II7 at one end of the adapter plate II6, and use the adapter plate bolt II11 to fix the assembly (including the lower single board 202 and the adapter plate II6) and the water baffle II7 together inside the power module housing 3.

[0023] After both sides of the single board are assembled, connect the wires between the upper single board 201 and the lower single board 202, and then connect the connector of the circuit board 2 to the connector on the power module housing 3. After all the connecting wires are connected, attach the assembly with the sealing plate 1 onto the assembly with the power module housing 3. There is a certain distance between the upper single board 201 and the lower single board 202 of the circuit board 2. The sealing plate 1 is sealed to the power module housing 3. Figure 1 , Figure 3 As shown, a sealing ring 12 is provided between the sealing plate 1 and the power module housing 3 to ensure sealing. Finally, the sealing plate 1 is fixed to the power module housing 3 with the sealing plate locking bolt 13.
