[0037] like Figures 1-5 The plastic housing panel shown is designed for easy installation of circuit boards and includes:

[0038] Door panel 1, on which mounting holes 2 are provided;

[0039] Panel 3 is detachably installed on mounting hole 2 of door panel 1. The area of ​​one side of panel 3 is larger than the area of ​​mounting hole 2. The other side of panel 3 is adapted to the mounting hole 2 and is suitable for passing through the mounting hole 2. A mounting cavity suitable for placing circuit board 14 is provided on the other side of panel 3. An insertion hole 9 is provided on the other side of panel 3. A connecting post 7 suitable for detachably connecting circuit board 14 is provided in the mounting cavity.

[0040] The fixing accessory 10 is detachably installed on the outer wall of the mounting cavity on the other side of the panel 3. The fixing accessory 10 is provided with a plug block 15 that is adapted to the plug hole 9. One end of the fixing accessory 10 is adapted to abut against the door panel 1.

[0041] This type of plastic shell panel, which facilitates the installation of circuit boards, features a panel 3 that is detachably connected to the door panel 1. The panel 3 has a mounting cavity for the circuit board 14, providing protection for it. When the panel 3 passes through the mounting hole 2 on the other side, it covers one side of the mounting hole 2, thus limiting the position of the panel 3 on one side of the door panel 1. Since one end of the fixing accessory 10 abuts against the door panel 1, the insertion block 15 on the fixing accessory 10, after being inserted into the insertion hole 9 on the side wall of the mounting cavity, also limits the position on the other side of the door panel 1. Thus, the panel 3, in conjunction with the fixing accessory 10, provides limiting on both opposite sides of the door panel 1, while simultaneously achieving a stable connection between the door panel 1 and the panel 3. When it is necessary to disconnect the door panel 1 and the panel 3, the fixing accessory 10 can be removed, disengaging the insertion block 15 from the insertion hole 9. This assembly connection structure is simple, effectively reducing assembly costs. The assembly connection method is simple and quick to operate, effectively improving assembly efficiency.

[0042] In this embodiment, the panel 3 includes a limiting plate 4 and a mounting frame 5 fixedly surrounding one side of the limiting plate 4. The side of the mounting frame 5 away from the limiting plate 4 is open, and a mounting cavity is formed inside the mounting frame 5. Specifically, two insertion holes 9 are provided on the side wall of the mounting frame 5. This arrangement can improve the connection strength between the panel 3 and the door panel 1 and prevent displacement after the panel 3 and the door panel 1 are connected. The limiting plate 4 has a button groove 6 that matches the button on the circuit board 14. Two connecting posts 7 are fixedly provided on the limiting plate 4, and threaded holes 8 are provided on the connecting posts 7.

[0043] In this embodiment, panel 3 is a plastic panel 3. This design benefits from the lightweight nature of plastic, which helps reduce the overall weight of the device; plastic has good insulation properties, effectively preventing short circuits and other electrical faults on the circuit board; plastic has a certain degree of corrosion resistance, making it suitable for use in humid or corrosive environments; plastic panel 3 can be processed through injection molding, cutting, drilling, and other processes, resulting in high production efficiency and allowing for easy design into various shapes and colors, enhancing the product's aesthetics; plastic material is recyclable and has good environmental performance; compared to metal materials, plastic panel 3 has lower costs and better economic benefits.

[0044] In this embodiment, the door panel 1 is a rectangular door panel 1, and the mounting holes 2 on it are rectangular mounting holes 2; specifically, the limiting plate 4 on the plastic panel 3 is rectangular, and the length and width dimensions of the rectangular limiting plate 4 are both larger than the length and width dimensions of the rectangular mounting holes 2; specifically, the mounting frame 5 on the plastic panel 3 forms a rectangular mounting cavity, and rectangular insertion holes 9 are provided on all four sides of the mounting frame 5, and the shape of the insertion block 15 is adapted to the shape of the insertion hole 9. Specifically, connecting posts 7 are fixedly provided on the four corners of the mounting cavity.

[0045] In this embodiment, the insert 15 is inclined, with the end of the insert 15 away from the fixing accessory 10 tilted upwards towards the side away from the door panel 1. This arrangement, while providing bidirectional positioning of the door panel 1 by the fixing accessory 10 and the panel 3, also improves the connection quality between the panel 3 and the door panel 1 through the inclined insert 15, preventing the insert 15 from slipping out of the insertion hole 9 without external force. Simultaneously, the inclined insert 15 allows the panel 3 to adapt to door panels 1 of different thicknesses, effectively improving the adaptability of the panel 3.

[0046] In this embodiment, connecting blocks 11 are provided at both ends and the middle of the fixing accessory 10. Through holes 12 are formed on the connecting blocks 11, and a connector 13 is provided on each of the three through holes 12. An insert 15 is located on the connecting block 11 in the middle. This arrangement improves the stability of the fixing accessory 10 on the panel 3 through the connectors 13. The fixing accessory 10 is securely connected to the panel 3 via the upwardly inclined insert 15, and the connectors 13 penetrate the three through holes 12, ensuring that the fixing accessory 10 is tightly abutted against the door panel 1, effectively guaranteeing the tightness and strength of the connection between the panel 3 and the door panel 1.

[0047] In this embodiment, only one end of each of the three connecting blocks 11 is fixed to the fixing accessory 10, and the three connecting blocks 11 and the fixing accessory 10 are integrally formed. The through hole 12 is a threaded connection hole, and specifically, the connecting piece 13 is a connecting bolt. This arrangement ensures the connection stability between the panel 3 and the door panel 1 through the precise fit between the connecting bolt and the threaded connection hole, and improves the ease of assembly during installation, connection, and disassembly of the door panel 1 and the panel 3 through the connecting screw and the threaded connection hole.

[0048] In summary, this type of plastic shell panel, which facilitates the installation of circuit boards, features a panel 3 that is detachably connected to the door panel 1. The panel 3 has a mounting cavity for the circuit board 14, providing protection for it. When the panel 3 passes through the mounting hole 2 on the other side, it covers one side of the mounting hole 2, thus limiting the position of the panel 3 on one side of the door panel 1. Since one end of the fixing accessory 10 abuts against the door panel 1, the insertion block 15 on the fixing accessory 10, after being inserted into the insertion hole 9 on the side wall of the mounting cavity, also provides a limiting effect on the other side of the door panel 1. Thus, the panel 3, in conjunction with the fixing accessory 10, provides limiting on both opposite sides of the door panel 1, while simultaneously achieving a stable connection between the door panel 1 and the panel 3. When it is necessary to disconnect the door panel 1 and the panel 3, the fixing accessory 10 can be removed, disengaging the insertion block 15 from the insertion hole 9. This assembly connection structure is simple, effectively reducing assembly costs. The assembly connection method is simple and quick to operate, effectively improving assembly efficiency.

[0049] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
