[0032] Shielding frame 1, with elastic buckles 11 provided on all four sides of the shielding frame 1;

[0033] Cover plate 2, with extension baffles 21 provided on all four sides of the cover plate 2, and a clamping portion provided on the inner side wall of the extension baffle 21;

[0034] When the cover plate 2 is installed on the shielding frame 1, the extension baffle 21 is located outside the elastic buckle 11, and the elastic buckle 11 is clamped to the clamping portion.

[0036] Further, the clamping portion is a clamping hole 22. When the cover plate 2 is installed on the shielding frame 1, the elastic buckle 11 is clamped in the clamping hole 22.

[0037] As can be seen from the above description, by designing the clamping portion as a clamping hole 22, the elastic buckle 11 can be clamped in the clamping hole 22, providing a more stable connection method. This design can prevent the loosening of the cover plate 2 caused by vibration or impact, and ensure the long-term stability and electromagnetic shielding effect of the shielding cover.

[0038] Further, the clamping hole 22 communicates with the outer side wall of the extension baffle 21. When the cover plate 2 is installed on the shielding frame 1, the elastic buckle 11 penetrates through the clamping hole 22.

[0039] As can be seen from the above description, the design of the elastic buckle 11 allows it to penetrate through the clamping hole 22.

[0042] Further, the number of the heat dissipation grooves 12 is multiple.

[0043] As can be seen from the above description, setting multiple heat dissipation grooves 12 can further improve the heat dissipation efficiency and ensure that the shielding cover can maintain good heat dissipation performance even during high-power or long-time operation.

[0044] Further, an identification layer is provided at one end of the elastic buckle 11 that penetrates through the clamping hole 22.

[0045] As can be seen from the above description, setting an identification layer at one end of the elastic buckle 11 that penetrates through the clamping hole 22 can provide visual or tactile feedback to help the assembler quickly identify and correctly install the cover plate 2.

[0046] Further, the material of the identification layer is a reflective material.

[0047] As can be seen from the above description, using a reflective material as the identification layer can provide better visibility in a dimly lit environment, facilitating the identification and assembly by the operator.

[0048] Further, the cross-sectional shape of the elastic buckle 11 is in an S shape, a Z shape or a C shape.

[0049] As can be seen from the above description, the shape of the elastic buckle 11 can be set according to the actual application requirements.

[0050] Further, the elastic buckle 11 and the shielding frame 1 are integrally formed as an integral structure.

[0051] As can be seen from the above description, through the integral forming technology, the elastic buckle 11 and the shielding frame 1 are manufactured as a whole, reducing the number of assembled parts, simplifying the production process, and at the same time improving the product consistency and reliability.

[0052] Further, the clamping portion is a clamping boss extending towards the inner side of the extending baffle 21. When the cover plate 2 is installed on the shielding frame 1, the elastic buckle 11 is clamped on the top of the clamping boss.

[0053] As can be seen from the above description, designing the clamping portion as a clamping boss extending towards the inner side of the extending baffle 21 enables the elastic buckle 11 to be clamped on the top of the boss. This design provides additional mechanical locking and enhances the connection strength between the cover plate 2 and the shielding frame 1.

Elastic buckles 11 are provided on four sides of the shielding frame 1; Extension baffles 21 are provided on four sides of the cover plate 2, and a clamping portion is provided on the inner side wall of the extension baffle 21; When the cover plate 2 is installed on the shielding frame 1, the extension baffle 21 is located outside the elastic buckle 11, and the elastic buckle 11 is clamped to the clamping portion; Specifically, by providing elastic buckles 11 on four sides of the shielding frame 1 and providing extension baffles 21 on four sides of the cover plate 2 for limiting, it is avoided that the cover plate 2 is displaced after being installed on the shielding frame 1; By clamping the elastic buckle 11 to the clamping portion on the inner side wall of the extension baffle 21, a simple and fast buckling method is realized. This design simplifies the assembly process, improves the assembly efficiency, enhances the stability and accuracy of the installation of the cover plate 2 and the shielding frame 1, and ensures the consistency of the product; More specifically, the elastic buckle 11 and the shielding frame 1 are an integrally formed one-piece structure, and the extension baffle 21 and the cover plate 2 are an integrally formed one-piece structure, reducing the number of assembled parts, simplifying the production process, and at the same time improving the consistency and reliability of the product.

[0056] In this embodiment, the clamping portion is a clamping hole 22. When the cover plate 2 is installed on the shielding frame 1, the elastic buckle 11 is clamped in the clamping hole 22; In this way, the elastic buckle 11 can be clamped in the clamping hole 22, providing a more stable connection method. This design can prevent the cover plate 2 from loosening due to vibration or impact, ensuring the long-term stability and electromagnetic shielding effect of the shielding cover; Specifically, the clamping hole 22 communicates with the outer side wall of the extension baffle 21. When the cover plate 2 is installed on the shielding frame 1, the elastic buckle 11 penetrates through the clamping hole 22. The design of the elastic buckle 11 allows it to penetrate through the clamping hole 22. This penetration design not only provides mechanical locking, but also enables the assembler to operate the elastic buckle 11 from the outside of the extension baffle 21, facilitating the assembler to fine-tune and disassemble the elastic buckle 11; More specifically, a heat dissipation groove 12 is provided at one end of the elastic buckle 11 facing away from the extension baffle 21, and the heat dissipation groove 12 communicates with the end of the elastic buckle 11 penetrating through the clamping hole 22. It is not difficult to understand that by providing the heat dissipation groove 12 at one end of the elastic buckle 11 facing away from the extension baffle 21, the heat energy generated by electromagnetic shielding can be effectively dissipated, keeping the temperature of the electronic device stable and extending the service life of the device; In detail, the number of the heat dissipation grooves 12 is multiple. Providing multiple heat dissipation grooves 12 can further improve the heat dissipation efficiency and ensure that the shielding cover can maintain good heat dissipation performance during high-power or long-term operation.

[0057] Optionally, one end of the elastic buckle 11 passing through the clamping hole 22 is provided with an identification layer (not shown in the figure). Providing an identification layer at one end of the elastic buckle 11 passing through the clamping hole 22 can provide visual or tactile feedback to help the assembler quickly identify and correctly install the cover plate 2. Specifically, the material of the identification layer is a reflective material. In this way, better visibility can be provided in a dim environment, facilitating the operator to identify and assemble. The reflective material includes, but is not limited to, glass bead type reflective film, microprism type reflective film or fluorescent full prism reflective film, which can be specifically selected according to actual application requirements. Further, the cross-sectional shape of the elastic buckle 11 is S-shaped, Z-shaped (as Figure 3 shown) or C-shaped, and the shape of the elastic buckle 11 can be specifically set according to actual application requirements.

[0058] In addition, in some other embodiments, the clamping portion may also be a clamping boss extending towards the inner side of the extending baffle 21. When the cover plate 2 is installed on the shielding frame 1, the elastic buckle 11 is clamped on the top of the clamping boss. Designing the clamping portion as a clamping boss extending towards the inner side of the extending baffle 21 enables the elastic buckle 11 to be clamped on the top of the boss. This design provides additional mechanical locking and enhances the connection strength between the cover plate 2 and the shielding frame 1.
