[0025] See also Figure 1 and Figure 2 The shielding cover 1000 includes a frame 1 and a cover 2. The frame 1 is provided with a receiving space 10. The cover 2 is provided on the frame 1. The cover 2 covers one end of the receiving space 10 to close one end of the receiving space 10. The cover 2 and the frame 1 are slidably connected.

[0026] For frame 1 above, see Figure 3 and Figure 4The frame 1 includes a side panel 11 and a receiving panel 12. The side panel 11 includes a first side panel 111, a second side panel 112, a third side panel 113, and a fourth side panel 114. The first side panel 111, the second side panel 112, the third side panel 113, and the fourth side panel 114 are connected end to end to form a receiving space 10. The first side panel 111 and the third side panel 113 are parallel to the first direction x, and the second side panel 112 and the fourth side panel 114 are parallel to the second direction y. The first side panel 111 and the third side panel 113 are each provided with an elongated through hole 13. The elongated through hole 13 is parallel to the first direction x and connects to the receiving space 10. The elongated through hole 13 is provided with a mounting hole 14 at one end near the second side panel 112. The diameter of the mounting hole 14 is greater than the width of the elongated through hole 13. The second side panel 112 is provided with connecting holes 1120 for screws to secure the cover panel 2 to the frame 1. The support plate 12 is perpendicularly connected to the first side panel 111, the second side panel 112, the third side panel 113, and the fourth side panel 114. The support plate 12 extends into one end of the receiving space 10 and supports the cover panel 2. The first direction x represents the length of the frame 1, and the second direction y represents the width of the frame 1. The first direction x and the second direction y are perpendicular to each other.

[0027] It can be understood that the long through holes 13 provided on the first side plate 111 and the third side plate 113 constitute guide rails of the frame 1 , and the guide rails are used for sliding connection with the cover plate 2 .

[0028] In some embodiments, a first limiting notch 115 is provided at both ends of the first side panel 111, a second limiting notch 116 is provided at both ends of the third side panel 113, a first limiting block 117 is provided at one end of the second side panel 112 and one end of the fourth side panel 114, and a second limiting block 118 is 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 strain resistance than an integrated or straight connection, thereby improving the mechanical stability of the frame 1.

[0029] For cover 2 above, see Figure 5Along the second direction y, connecting plates 21 extend from both sides of the cover plate 2. The connecting plates 21 are used to close the elongated through-hole 13. A guide block 22 is provided at one end of the connecting plate 21. The guide block 22 has a limiting groove 220. The limiting groove 220 is used to cooperate with the edge of the elongated through-hole 13 to enable the guide block 22 to slide along the elongated through-hole 13, thereby achieving the sliding of the cover plate 2 relative to the frame 1. A fixing plate 23 extends from the edge of the cover plate 2 away from the guide block 22. The fixing plate 23 has fixing holes 230 for screws to pass through to secure the cover plate 2 to the frame 1.

[0030] It can be understood that the structure of the guide rail and the guide block 22 is not limited to the above-mentioned limitations, and can also be other structures. For example, the guide rail is a long through hole 13 provided only on the first side plate 111 or the third side plate 113, and accordingly, the number of the guide block 22 is also one, or the guide rail is a long groove provided on the first side plate 111 and / or the third side plate 113, or the guide block 22 is provided at both ends of the connecting plate 21.

[0031] When the cover plate 2 is installed on the frame 1, the guide block 22 of the cover plate 2 is inserted into the mounting hole 14 at one end of the elongated through hole 13, and the edge of the elongated through hole 13 is snapped into the limit groove 220 of the guide block 22. Then, the cover plate 2 slides along the elongated through hole 13 until it slides to the other end of the elongated through hole 13. At this time, the fixing plate 23 contacts the second side plate 112. Finally, screws are sequentially passed through the fixing holes 230 of the cover plate 2 and the connecting holes 1120 of the second side plate 112 to fix the cover plate 2 to the frame 1. When removing the cover plate 2 from the frame 1, after loosening the screws, move the cover plate 2 so that the guide block 22 moves from the other end of the elongated through hole 13 to the one end, and then withdraws from the mounting hole 14 to remove the cover plate 2 from the frame 1.

[0032] It should be noted that the shielding cover 1000 is made of metal or other materials with electromagnetic shielding function.

[0033] In the embodiment of the present invention, the shielding cover 1000 includes a frame 1 and a cover 2. The frame 1 includes side panels 11, which enclose a receiving space 10. The side panels 11 are provided with guide rails. The cover 2 is provided at one end of the receiving space 10 to close the receiving space 10. A connecting plate 21 extends from the edge of the cover 2. A guide block 22 is provided at one end of the connecting plate 21. The guide block 22 can slide within the guide rail to enable the cover 2 to slide relative to the frame 1. In this manner, the cover 2 is slidably connected to the frame 1, facilitating installation and removal of the cover 2 and the frame 1.

[0034] The present invention also provides an embodiment of a circuit board assembly 4000, see Figure 6The circuit board assembly 4000 includes a circuit board 2000, an electronic component 3000 and the above-mentioned shielding cover 1000. The shielding cover 1000 and the electronic component 3000 are both arranged on the circuit board 2000. The shielding cover 1000 covers the electronic component 3000. The electronic component 3000 is located in the receiving space 10. The shielding cover 1000 performs an electromagnetic shielding effect on the electronic component 3000. For the structure and function of the shielding cover 1000, please refer to the above-mentioned embodiment and will not be described here one by one.

[0035] In an embodiment of the present invention, the frame 1 and the cover 2 of the shielding cover 1000 are slidably connected. When the electronic component 3000 in the receiving space 10 needs to be repaired or replaced, there is no need to remove the shielding cover 1000 as a whole. The electronic component 3000 can be operated by simply sliding and removing the cover 2, which reduces maintenance costs and improves maintenance efficiency.

[0036] The present invention further provides an embodiment of an electronic device, which includes the above-mentioned circuit board assembly 4000.
