[0025] The present utility model provides a shielding cover. Figure 1 and Figure 2 is a specific embodiment of the shielding cover provided by the present utility model.

[0026] Referring to Figure 1 and Figure 2 , the shielding cover includes a cover main body 1 and a cover plate 2. The cover main body 1 is used for welding with a PCB board. A surrounding frame 11 is provided on a side of the cover main body 1 away from the PCB board. An opening 12 is formed inside the surrounding frame 11. The cover plate 2 is used for closing the opening 12.

[0027] Interleaved baffle plates 21 and elastic pieces 22 are provided on the side surface of the cover plate 2. The baffle plate 21 is attached to one side of the surrounding frame 11, and the elastic piece 22 extends into the opening 12 and is attached to the other side of the surrounding frame 11.

[0028] In this embodiment, by arranging alternating baffle plates 21 and elastic pieces 22 on the side surface of the cover plate 2, the baffle plates 21 and the elastic pieces 22 are respectively attached to both sides of the enclosure. Through the elastic force of the elastic pieces 22, the baffle plates 21 and the elastic pieces 22 can generate a clamping force on the enclosure, so that the cover plate 2 can be fixed on the cover body 1. This fixing method is simple, and the cover plate 2 does not need to be sleeved on the cover body 1, which will not thicken the side wall of the shielding cover and is beneficial to the heat dissipation of the shielding cover; moreover, the size of the cover plate 2 only needs to be sufficient to close the opening 12, with less material used and lower cost.

[0029] Furthermore, a rivet 211 is provided on the baffle plate 21, and a rivet hole 111 corresponding to the position of the rivet 211 is formed in the frame 11, and the rivet 211 is riveted to the rivet hole 111. In this embodiment, on the basis that the cover plate 2 and the cover body 1 are fixed by the elastic pieces 22 and the baffle plates 21, they can also be fixed by riveting the rivet 211 and the rivet hole 111. This design can further increase the fixing stability of the cover plate 2 and the cover body 1, ensuring that the cover plate 2 is firmly fixed on the cover body 1 and is not easy to loosen or fall off; specifically, a gasket is provided on the fitting surface of the baffle plate 21, and the gasket can make the baffle plate 2 fit more closely with the enclosure, making the force on the baffle plate 2 and the enclosure more uniform, thereby increasing the connection stability between the cover plate 2 and the cover body 1.

[0030] Furthermore, a through hole 23 is formed in the cover plate 2, and the through hole 23 is located between the baffle plate 21 and the elastic piece 22. In this embodiment, by providing the through hole 23, it can help the electronic components in the cover body 1 dissipate heat, increase the heat dissipation efficiency, and facilitate the processing of the baffle plate 21 and the elastic piece 22 on the cover plate 2, and also make the assembly between the cover plate 2 and the enclosure easier.

[0031] Furthermore, a positioning post is provided on the fitting surface of the baffle plate 21, and a positioning hole (not shown in the figure) for the positioning post to extend into is formed in the frame 11. In this embodiment, by providing a positioning post on the baffle plate 21 and forming a corresponding positioning hole in the frame 11, precise positioning between the baffle plate 21 and the frame 11 can be achieved. The positioning post can accurately guide the installation position of the baffle plate 21, ensuring the alignment and fitting between the baffle plate 21 and the frame 11. It can also improve the connection stability between the baffle plate 21 and the frame 11. The positioning post provides additional support and fixing points, which can prevent the baffle plate 21 from loosening or shifting during use, ensuring the structural stability and reliability of the shielding cover.

[0032] Furthermore, a guiding structure is provided at the end of the positioning post. Specifically, the guiding structure is set as a hemispherical structure. In this embodiment, the hemispherical structure has an arc-shaped surface. During the assembly process of the positioning post and the positioning hole, the arc-shaped surface can play a guiding role, making it easier for the positioning post to extend into the positioning hole and making the assembly simpler.

[0033] Further, the fitting surface of the elastic piece 22 is set as an inclined surface, and the inclined surface inclines towards the surrounding frame 11 from one end close to the side surface of the cover plate 2 to the end far from the side surface of the cover plate 2. For the convenience of description, here, it is taken that the PCB board is located on the lower side of the cover body 1, and the retaining piece 21 and the elastic piece 22 are respectively located on the upper side and the lower side of the enclosure. It can be understood that during assembly, the elastic piece 22 will be bent and deformed, specifically, it inclines downward from the end close to the cover plate 2 to the end far from the cover plate 2. In this embodiment, by setting the fitting surface of the elastic piece 22 to incline upward from the end close to the side surface of the cover plate 2 to the end far from the side surface of the cover plate 2, the elastic piece 22 can be more closely fitted with the enclosure, and the force on the elastic piece 22 and the enclosure is more uniform, thereby increasing the fixing stability between the cover plate 2 and the cover body 1.

[0034] Further, the cover body 1 is set as a bending and forming structure. In this embodiment, setting the cover body 1 as a bending and forming structure can increase the strength and rigidity of the cover body 1, enabling it to withstand external impacts and vibrations, better protecting the internal electronic components, and the bending and forming structure usually has a relatively simple manufacturing process. This design can reduce production costs, improve production efficiency, and reduce the number of parts, simplifying the overall structure of the cover body 1.

[0035] Further, the number of the retaining pieces 21 is set to at least four. Specifically, the number of the retaining pieces 21 is set to four, and the four retaining pieces 21 are respectively arranged at the four corners of the cover plate 2. In this embodiment, by arranging the four retaining pieces 21 at the four corners of the cover plate 2, the overall force on the cover plate 2 can be more uniform, which is beneficial to the fixing stability between the cover plate 2 and the cover body 1.

[0036] Further, the number of the rivets 211 is set to at least four. Specifically, the number of the rivets 211 is set to four, and the four rivets 211 are respectively arranged on the four retaining pieces 21 located at the four corners of the cover plate 2. In this embodiment, by arranging the rivets 211 at the four corners of the cover plate 2, the riveting between the cover plate 2 and the cover body 1 can be more stable.

[0037] The above are only the optional embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. All equivalent structural transformations made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present utility model.
