[0002] PCBs, also known as printed circuit boards (PCBs), are essential components in the electronics industry. Virtually every electronic device, from small electronic watches and calculators to large computers, communications equipment, and military weapon systems, that incorporates integrated circuits and other electronic components, requires a PCB to interconnect them. To prevent radiation from the electronic circuits on PCBs during operation and to shield electronic components from interference, shielding covers are often installed on the outside of the PCBs during production.

[0003] When inspecting the circuit connection in the shielding area of the motherboard, the shielding cover needs to be removed. However, due to the product structure, the connection between the shielding cover and the motherboard is very tight. Removing the shielding cover is time-consuming and labor-intensive. In addition, the shielding cover is damaged after removal and cannot be reused. Therefore, we propose a motherboard shielding cover structure. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 , the utility model provides a technical solution:

[0028] A motherboard shielding cover structure includes a motherboard body 10, and further includes: fixing blocks 101 fixedly connected to both sides of the motherboard body 10, the motherboard body 10 is rectangular, the fixing blocks 101 are arranged oppositely, and are fixedly connected in two groups, elastic plates 201 are respectively provided on both sides of the outside of the shielding cover body 20, the shielding cover body 20 is movably connected to the fixing blocks 101 through the elastic plates 201, and the number of elastic plates 201 is the same as the number of fixing blocks 101, and a fixing assembly 11 is provided between the shielding cover body 20 and the motherboard body 10 so as to clamp the elastic plates 201 inside the fixing blocks 101 to fix the shielding cover body 20 to the motherboard body 10, and an alignment assembly 12 is provided between the two oppositely arranged groups of elastic plates 201 to align the shielding cover body 20 with the motherboard body 10 and guide the fixing assembly 11;

[0029] The alignment assembly 12 can realize the quick alignment of the shield cover body 20 and the mainboard body 10 , thereby facilitating the quick installation and quick disassembly between the fixing block 101 and the elastic plate 201 , and between the fixing block 101 .

[0030] The fixing assembly 11 includes a slot 111 formed on one side of the fixing block 101, a block 112 fixedly connected to one side of the elastic plate 201, the slot 111 matching the block 112, and guide surfaces 113 formed on both sides of the block 112. A guide groove 114 is formed on one side of the fixing block 101 close to the slot 111, and the guide groove 114 forms an angle with the side wall of the fixing block 101. A guide sliding surface 115 is provided on one side of the elastic plate 201 for matching with the guide groove 114.

[0031] The fast disassembly and assembly between the shielding cover body 20 and the mainboard body 10 is achieved by the cooperation between the clamping block 112 and the clamping slot 111 .

[0032] The alignment assembly 12 includes an alignment plate 121 fixedly connected to both sides of the main board body 10, and an alignment groove 122 is formed on the alignment plate 121. A plug-in plate 123 is fixedly connected between the two sets of elastic plates 201 of the shielding plate body, and an alignment column 124 is fixedly connected to the plug-in plate 123, and the alignment column 124 matches the alignment groove 122. The plug-in plate 123 is integrally formed with the elastic material. The alignment column 124 is provided in two groups and is symmetrically arranged along the length direction of the plug-in plate 123, and the alignment column 124 is triangular in shape.

[0033] In order to facilitate the rapid alignment of the shielding cover body 20 and the mainboard body 10 and avoid deviation between the two during installation and disassembly, which affects the stability of the connection between the two, the alignment column 124 on the plug-in board 123 is aligned with the alignment slot 122, and the alignment column 124 is triangular in shape and can also play a limiting role to avoid deviation during the alignment process, so that the position is determined once it is aligned, thereby facilitating the fixed connection between the block 112 and the slot 111.

[0034] Both sides of the shielding cover body 20 are fixedly connected with arc-shaped pull plates 202 for disassembly and assembly, which can facilitate the shielding cover body 20 to be separated from the mainboard body 10 by lifting the arc-shaped pull plates 202 during maintenance.

[0035] Specific implementation process:

[0036] During installation, first align the alignment column 124 and the plug board 123 to align the alignment groove 122. Since the alignment column 124 is triangular, the alignment column 124 and the plug board 123 can quickly determine the connection position between the main body 10, and the alignment plate 121 is made of elastic material. The alignment plate 121 can not only limit the plug board 123, but also the alignment groove 122 can limit the alignment column 124. Therefore, once the position is determined, there is no need to adjust the position of the shield cover body 20. Apply a downward pressure to the shield cover body 20. At this time, the elastic plate 201 Under the limiting effect of the fixing blocks 101 on both sides, the guide sliding surface 115 of the elastic plate 201 contacts the guide groove 114, so that the elastic plate 201 can gradually deform in the opposite direction, and the downward pressure is continuously applied until the clamping block 112 moves along the inner side wall of the fixing block 101 to the position of the clamping groove 111. At this point, the clamping groove 111 just releases the limiting effect on the clamping block 112. Under the elastic restoring force of the elastic plate 201, the clamping block 112 is clamped in the position of the clamping groove 111, thereby completing the fixation and realizing the quick connection between the shielding cover body 20 and the mainboard body 10.

[0037] When disassembling, one only needs to pull the curved handle with his hand to apply an upward pulling force to the shielding cover body 20, so that the elastic plate 201 is subjected to force, and the opposite movement mentioned above occurs, thereby enabling rapid disassembly between the shielding cover body 20 and the mainboard body 10, thereby solving the problem that the shielding cover is damaged after disassembly and cannot be reused.
