[0029] See also Figure 1 and Figure 2 The shielding cover 100 includes a frame 1 and a cover 2. The frame 1 is provided with a receiving space 10. The cover 2 is arranged on the frame 1. The cover 2 covers one end of the receiving space 10 to close the one end of the receiving space 10. The cover 2 and the frame 1 are slidably connected.

[0030] For frame 1 above, see Figures 3 to 6 The frame 1 includes a side plate 11 and a receiving plate 12. The side plate 11 includes a first side plate 111, a second side plate 112, a third side plate 113 and a fourth side plate 114. The first side plate 111, the second side plate 112, the third side plate 113 and the fourth side plate 114 are connected end to end in sequence and enclose a receiving space 10. The first side plate 111 and the third side plate 113 are parallel to the first direction x, and the second side plate 112 and the fourth side plate 114 are parallel to the second direction y. The outer surfaces of the first side plate 111 and the third side plate 113 facing away from the receiving space 10 are provided with convex strips 13, and the length of the convex strips 13 is less than or equal to the length of the first side plate 111. The fourth side plate 114 extends along the third direction z with a clamping plate 14, which is perpendicular to the fourth side plate 114, and the surface of the clamping plate 14 facing the receiving space 10 is provided with a first clamping block 141, and the first clamping block 141 is used to abut and fix with the cover plate 2. The receiving plates 12 are vertically connected to the first side plate 111 , the second side plate 112 , the third side plate 113 and the fourth side plate 114 . The receiving plates 12 extend into one end of the receiving space 10 . The receiving plates 12 are used to support the cover plate 2 .

[0031] Among them, the first direction x is the length direction of the frame 1, the second direction y is the width direction of the frame 1, and the third direction z is the height direction of the frame 1. The first direction x and the second direction y are perpendicular to each other, and the third direction z is perpendicular to the first direction x and the second direction y.

[0032] In some embodiments, first limiting notches 115 are provided at both ends of the first side panel 111, second limiting notches 116 are provided at both ends of the third side panel 113, first limiting blocks 117 are provided at one end of the second side panel 112 and one end of the fourth side panel 114, and second limiting blocks 118 are provided at the other end of the second side panel 112 and the other end of the fourth side panel 114. The first limiting block 117 cooperates with the first limiting notch 115, and the second limiting block 118 cooperates with the second limiting notch 116 to connect the first side panel 111, the second side panel 112, the third side panel 113 and the fourth side panel 114 end to end. Moreover, the limiting blocks and the limiting notches are connected in a coordinated manner, which has better anti-deformation ability than an integrated or straight connection, thereby improving the mechanical stability of the frame 1.

[0033] For cover 2 above, see Figures 7 to 9 , along the second direction y, connecting plates 21 extend from both side edges of the cover plate 2, and the connecting plates 21 are provided with slide grooves 211, which are used to slide with the convex strips 13, so that the cover plate 2 slides along the convex strips 13, thereby realizing the sliding of the cover plate 2 relative to the frame 1. The direction from the bottom of the slide groove 211 to the notch is parallel to the second direction y, and the width of the notch of the slide groove 211 is equal to the distance between the convex strip 13 and the edge of one end of the receiving space 10, so that the cover plate 2 can be tightly covered on one end of the receiving space 10. A second clamping block 22 is provided at one end of the cover plate 2 facing away from the surface of the receiving space 10, and the abutting direction of the second clamping block 22 is opposite to that of the first clamping block 141, and the second clamping block 22 is used to abut against the first clamping block 141 to fix the cover plate 2 to the frame 1.

[0034] In some embodiments, a limiting plate 23 is extended from the other end of the cover 2 away from the second clamping block 22, and the limiting plate 23 is perpendicular to the surface of the cover 2. When the cover 2 is installed on the frame 1, the limiting plate 23 contacts the second side plate 112. The limiting plate 23 increases the stability of the cover 2 and provides a certain sealing effect, thereby reducing the possibility of external dust or debris entering the receiving space 10.

[0035] It is understandable that the structure of the frame 1 and the cover plate 2 is not limited to the above, and can also be other structures. For example, the convex strip 13 is only provided on the first side plate 111 or the third side plate 113, and accordingly, the cover plate 2 is only provided with a slide groove 211, or the frame 1 and the cover plate 2 are not provided with the first clamping block 141 and the second clamping block 22, and the frame 1 and the cover plate 2 are fixed by screws.

[0036] When the cover 2 is installed on the frame 1, one end of the cover 2 with the first block 141 is firstly arranged at the end of the frame 1 away from the second block 22, and the convex strip 13 is received in the slide groove 211. The cover 2 slides toward the other end of the frame 1, and the slide groove 211 slides relative to the convex strip 13 until the first block 141 and the second block 22 abut against each other.

[0037] It is understandable that the clamping plate 14 is made of elastic material. When the cover plate 2 is removed from the frame 1 , the cover plate 2 is dragged along the frame 1 to disengage the first clamping block 141 from the second clamping block 22 , and then the cover plate 2 can be slidably removed.

[0038] It should be noted that the shielding cover 100 is made of metal or other materials with electromagnetic shielding function.

[0039] In the embodiment of the utility model, the shielding cover 100 includes a frame 1 and a cover plate 2. The frame 1 includes a side plate 11. The side plate 11 encloses a receiving space 10. The surface of the side plate 11 facing away from the receiving space 10 is provided with a convex strip 13. One end of the frame 1 is provided with a first clamping block 141. The cover plate 2 is provided at one end of the receiving space 10 to close one end of the receiving space 10. A connecting plate 21 extends from the edge of the cover plate 2. The connecting plate 21 is provided with a slide groove 211. The slide groove 211 and the convex strip 13 are slidably matched to enable the cover plate 2 to slide relative to the frame 1. One end of the cover plate 2 is provided with a second clamping block 22. The second clamping block 22 is used to abut against the first clamping block 141 to fix the cover plate 2 to the frame 1. In the above manner, the cover plate 2 is slidably connected to the frame 1, which is convenient for installation and disassembly.

[0040] The present invention also provides a circuit board assembly 400 embodiment, see Fig.10 The circuit board assembly 400 includes a circuit board 200, an electronic component 300 and the above-mentioned shielding cover 100. The shielding cover 100 and the electronic component 300 are both arranged on the circuit board 200. The shielding cover 100 covers the electronic component 300. The electronic component 300 is located in the receiving space 10. The shielding cover 100 plays an electromagnetic shielding role for the electronic component 300. For the structure and function of the shielding cover 100, please refer to the above-mentioned embodiment, which will not be described one by one here.

[0041] In the embodiment of the utility model, the frame 1 and the cover plate 2 of the shielding cover 100 are slidably connected. When the electronic component 300 in the receiving space 10 needs to be repaired or replaced, there is no need to remove the shielding cover 100 as a whole. The electronic component 300 can be operated by only sliding and removing the cover plate 2, which reduces maintenance costs and improves maintenance efficiency.

[0042] The utility model further provides an electronic device embodiment, the electronic device includes the above-mentioned circuit board assembly 400, the structure and function of the circuit board assembly 400 can refer to the above-mentioned embodiment, and will not be described in detail here.
