[0024] 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.

[0025] Referring to Figure 1 And Figure 2 , the shielding cover includes a cover body 1, the cover body 1 is used for welding with a PCB board, and a plurality of first contact components 2 are arranged on the welding surface of the cover body 1. The first contact components 2 include a first patch 21 that fits the PCB board and a first elastic piece 22 arranged on one side of the first patch 21. The first elastic piece 22 abuts against the PCB board.

[0026] The cover body 1 includes a first side surface. An opening 10 is arranged on the first side surface of the cover body 1, and a plurality of second contact components are arranged on the first side surface of the cover body 1. The second contact components include second elastic pieces 32 for abutting against electrical components.

[0027] In this embodiment, through the first elastic piece 22 and the second elastic piece 32, the cover body 1 can be electrically connected to the electrical component and the PCB board respectively, so that the static electricity on the surface of the electrical component can be conducted to the PCB board through the cover body 1, avoiding continuous accumulation of static electricity, generating potential difference and affecting the working state of the electrical component; through the first patch 21, the contact area between the cover body 1 and the PCB board can be increased, making the connection between the cover body 1 and the PCB board more stable.

[0028] Specifically, the electromagnetic module of the electrical component extends into the cover body 1 from the opening 10, and the electromagnetic module is shielded by the cover body 1.

[0029] Furthermore, the second contact component further includes a second patch 31 that fits the electrical component, and the second elastic piece 32 is disposed on one side of the second patch 31. In this embodiment, by providing the second patch 31 that fits the electrical component, the contact area between the cover body 1 and the electrical component can be increased, improving the flatness and stability of the contact surface between the two. The second patch 31 can effectively disperse the pressure from the cover body 1, reducing local stress concentration, thereby protecting the surface of the electrical component and avoiding damage or deformation caused by mechanical stress.

[0030] Furthermore, positioning pieces 11 are provided at both ends of the abutting surface of the cover body 1, and positioning slots for inserting the positioning pieces 11 are provided on the PCB board. In this embodiment, through the cooperation of the positioning pieces 11 and the positioning slots, it can be ensured that the cover body 1 is accurately aligned when welded to the PCB board, avoiding deviation and ensuring precise welding; it can also increase the mechanical connection strength between the cover body 1 and the PCB board, preventing the cover body 1 from loosening or shifting due to vibration or external force during use, and improving the stability of the overall structure.

[0031] Furthermore, a plurality of through holes 12 are provided at the bottom of the side surface of the cover body 1. In this embodiment, by providing the through holes 12, the air convection inside and outside the cover body 1 can be increased, helping the electrical components inside the cover body 1 to dissipate heat and increasing the heat dissipation efficiency.

[0032] The cover body 1 is arranged as a bent and formed structure. In this embodiment, the bent and formed structure usually has a relatively simple manufacturing process. This design can reduce production costs, improve production efficiency, and reduce the number of components, simplifying the overall structure of the cover body 1. Moreover, it can increase the strength and rigidity of the cover body 1, enabling it to withstand external impacts and vibrations and better protect the internal electrical components. During the specific bending process: in the initial state, the four bending plates are in the same plane. At this time, taking the first bending plate 13 as the reference, the second bending plate 14 is bent downward so that the first bending plate 13 is perpendicular to the second bending plate 14, and then the third bending plate 15 and the fourth bending plate 16 are bent downward so that both the third bending plate 15 and the fourth bending plate 16 are perpendicular to the first bending plate 13.

[0033] Further, the cover body 1 includes a first bending plate 13, a second bending plate 14, a third bending plate 15, and a fourth bending plate 16. The third bending plate 15 and the fourth bending plate 16 are arranged oppositely, and the first bending plate 13 and the second bending plate 14 are connected and both are located between the third bending plate 15 and the fourth bending plate 16. Specifically, the first bending plate 13 is parallel to the PCB board. The third bending plate 15 and the fourth bending plate 16 are respectively arranged at both ends of the first bending plate 13 and are perpendicular to the first bending plate 13. The second bending plate 14 is perpendicular to the first bending plate 13, the third bending plate 15, and the fourth bending plate 16 respectively.

[0034] Further, clamping blocks 17 are provided at both ends of the second bending plate 14, and clamping grooves 18 for engaging with the clamping blocks 17 are provided on both the third bending plate 15 and the fourth bending plate 16. In this embodiment, after bending and forming, through the engagement of the clamping blocks 17 and the clamping grooves 18, the second bending plate 14 can be stably connected to the third bending plate 15 and the fourth bending plate 16, preventing loosening, and improving the stability of the overall structure of the cover body 1. The second bending plate 14 is engaged with the third bending plate 15 and the fourth bending plate 16 through the clamping blocks 17 and the clamping grooves 18, without the need for additional connecting parts for fixation, and the structure is simpler.

[0035] Further, limiting structures 19 for abutting against the second bending plate 14 are provided on both the third bending plate 15 and the fourth bending plate 16. In this embodiment, the limiting structures 19 can be used as a positioning reference during bending. During the bending process of the third bending plate 15 and the fourth bending plate 16, the limiting structures 19 will abut against the second bending plate 14 to ensure that the third bending plate 15 and the fourth bending plate 16 are bent to be perpendicular to the first bending plate 13, and the problem of excessive bending can be avoided.

[0036] The above are only the optional embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
