[0002] Shielding covers are not only used in electronic equipment, but are also widely used in various high-voltage electrical and other industries to ensure that related equipment can operate normally without being affected by external interference.

[0003] After the traditional shielding cover covers the shielded object, it is connected and fixed to the base with bolts. Therefore, multiple sets of bolts are required to fix the shielding cover around it, which is inefficient. At the same time, some connection methods that connect the upper and lower cover bodies often cause the upper and lower cover bodies to deform and cannot be connected. The angle needs to be adjusted multiple times, which is more troublesome to operate. In addition, this type of connection method requires the lower cover body to be fixed around the shielding cover before it can be snap-fitted and connected, which is also inefficient.

[0026] like Figure 1-5 As shown, a snap-fit ​​shielding cover comprises a shielding cover 1, a left clamping body 2, and a right clamping body 3; a notch 1011 is provided at the bottom of the left side plate 101 of the shielding cover 1, a wedge block 4 is provided on the outer side above the notch 1011, a left buckle 5 is provided below the wedge block 4, and the left buckle 5 extends inward; a right buckle 6 is provided at the bottom of the right side plate 102 of the shielding cover 1, and the right buckle 6 extends outward;

[0027] The left clamp body 2 is composed of a fixed plate 201, a sliding plate 202, a left base 203, and a left fixed buckle 204. The fixed plate 201, the sliding plate 202, and the left fixed buckle 204 are fixed on the left base 203 from left to right in sequence. A return spring 7 is provided between the fixed plate 201 and the sliding plate 202. A wedge-shaped groove 2021 is provided on the side of the sliding plate 202 facing the wedge block, and the opening direction of the left fixed buckle 204 faces the sliding plate 202.

[0028] The right clamp body 3 is composed of a right base 301 and a right fixing buckle 302. The right fixing buckle 302 is fixed on the right base 301. The opening direction of the right fixing buckle 302 is on the same side as the opening direction of the left fixing buckle 204. After the right fixing buckle is docked, the overall shielding cover is fixed.

[0029] like Figure 2 As shown, a transverse fixing block 8 is provided at the bottom of the sliding plate 202 facing the fixing plate 201 , and a transverse wedge-shaped groove 801 is provided on the transverse fixing block 8 , and the wedge-shaped groove is used for docking with subsequent transverse wedge blocks.

[0030] like Figure 2 As shown, a transverse wedge block 9 is provided between the fixed plate 201 and the sliding plate 202. The transverse wedge block 9 slides in cooperation with the transverse wedge groove 801 to ensure that the sliding plate can move in a guided state.

[0031] like Figure 2 As shown, when the sliding plate 202 moves to contact with the left fixed buckle 204, the transverse wedge block 9 and the transverse wedge groove 801 do not disengage and remain in an engaged state; when the transverse fixed block 8 moves to the minimum stroke of the return spring, the distance between the sliding plate 202 and the left fixed buckle 204 is greater than the length of the left buckle 5, ensuring that the sliding plate can always be in a guided state when moving back and forth to avoid displacement.

[0032] like Figure 4 As shown, the lower edge of the wedge block 4 extends downward to the middle of the notch 1011, and the left buckle 5 does not conflict with the top plane of the notch 1011 and leaves a gap, and the gap height is greater than the thickness of the top plate of the left fixing buckle 204; the distance from the left buckle 5 to the bottom of the shielding cover 1 is greater than the thickness of the left base 203, and the gap between the left buckle 5 and the top plane of the notch 1011 is used for docking with the left fixing buckle, and the gap from the left buckle to the bottom of the shielding cover is used for docking with the base, ensuring that the left buckle can be inserted into the left fixing buckle.

[0033] like Figure 2 As shown, the return springs 7 are divided into two groups and are placed in sequence along the vertical direction. The two groups of springs can increase the elastic force, and one group can be used as a backup spring. After one group of springs fails, the other group of springs can still provide return force to ensure that the shielding cover can be compressed.

[0034] like Figure 3As shown, the right fixing buckle 302 is integrally connected to the right base 301, and the right fixing buckle 302 is placed on the left edge of the right base 301, that is, the right base is completely exposed outside the shielding cover, so there is no need to open a notch on the right side plate of the shielding cover, reducing the mold opening steps of the shielding cover and improving efficiency.
