When an element is described as "connected to" another element, it can be directly connected to the other element, or there can be one or more centered elements therebetween. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this specification are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by technicians in the technical field of the present invention. The terms used in this specification are only for the purpose of describing specific embodiments and are not used to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[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 connected by snapping.

[0030] For frame 1 above, see Figures 3 to 6The frame 1 includes a side plate 11 and a receiving plate 12. The side plate 11 encloses a receiving space 10. The receiving plate 12 is connected to the side plate 11 vertically, and the receiving plate 12 extends into the receiving space 10. A clamping hole 13 is provided at one end of the side plate 11. The number of the clamping holes 13 is at least two. The clamping holes 13 are arranged around the edge of one end of the side plate 11. The clamping holes 13 are used to be clamped and connected with the second clamping structure of the cover plate 2. The shape of the clamping hole 13 matches the shape of the second clamping structure. 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. First limiting notches 14 are respectively provided on both sides of the first side panel 111, second limiting notches 15 are respectively provided on both sides of the third side panel 113, first limiting blocks 16 are provided on one side of the second side panel 112 and one side of the fourth side panel 114, second limiting blocks 17 are provided on the other side of the second side panel 112 and the other side of the fourth side panel 114, the first limiting notch 14 and the first limiting block 16 cooperate with each other, and the second limiting notch 15 and the second limiting block 17 cooperate with each other.

[0031] It can be understood that, through the above-mentioned method, the turning point of the side panel 11 is connected by the limiting notch and the limiting block, which has better structural stability and impact resistance than the integrated side panel.

[0032] In some embodiments, a plurality of connecting protrusions 18 extend from the other end of the side plate 11 . The connecting protrusions 18 are used to be snapped onto an external device so as to fix the shielding cover 100 to the external device.

[0033] For cover 2 above, see Figure 7 and Figure 8 A block 21 extends from the cover plate 2, and the cover plate 2 is provided with notches 20 on both sides of the block 21. There are at least two blocks 21, and the blocks 21 are arranged around the edge of the cover plate 2. The plurality of blocks 21 constitute the second clamping structure of the cover plate 2. The block 21 includes an extension portion 211 and a protrusion 212. One end of the extension portion 211 is connected to the cover plate 2, and the protrusion 212 is arranged on both sides of the other end of the extension portion 211. The protrusion 212 is arc-shaped.

[0034] It is understandable that the notches 20 of the cover plate 2 on both sides of the block 21 make the block 21 more flexible, so that the block 21 can be smoothly inserted into the hole 13 of the frame 1. At the same time, the arc-shaped design of the protrusion 212 can increase the contact area between the block 21 and the hole 13, provide a stable clamping effect, and prevent the shielding cover 100 from shaking or falling off during use.

[0035] In some embodiments, the specific settings of the first clip structure and the second clip structure are not limited to the above, and may also be other structures. For example, the first clip structure is a clip hole provided in the frame 1, and the second clip structure is a clip hook extending from the cover plate 2, and the clip hook is engaged with the clip hole.

[0036] When the cover plate 2 is installed on the frame 1, the receiving plate 12 supports the cover plate 2. The setting of the receiving plate 12 enhances the connection stability between the cover plate 2 and the frame 1. The block 21 of the cover plate 2 is correspondingly inserted into the hole 13 of the frame 1. The outer surface of the block 21 does not protrude from the edge of the cover plate 2 and the surface of the side plate 11, so that the surface of the shielding cover 100 remains flat and beautiful, avoiding interference or collision of the shielding cover 100 during assembly or use.

[0037] It should be noted that the shielding cover 100 is made of metal material or other materials with electromagnetic shielding function.

[0038] 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 and a receiving plate 12. A clamping hole 13 is arranged around one end of the side plate 11. A clamping block 21 extends around the edge of the cover plate 2. The receiving plate 12 is used to support the cover plate 2. The clamping block 21 is engaged with the clamping hole 13 to clamp the cover plate 2 and the frame 1. The clamping connection between the frame 1 and the cover plate 2 makes the shielding cover 100 easy to install and disassemble. When the shielding cover 100 is used to cover electronic components and the electronic components need to be replaced or repaired, only the cover plate 2 of the shielding cover 100 needs to be disassembled, and the shielding cover 100 does not need to be disassembled as a whole, which improves work efficiency and reduces maintenance costs.

[0039] The utility model also provides a circuit board assembly 1000 embodiment, please refer to Fig. 9 The circuit board assembly 1000 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 and 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.
