Description

Technical Field

[0001] This utility model relates to the field of shielding technology, and in particular to an electromagnetic interference-enhanced shielding cover. Background Technology

[0002] Electronic devices typically contain circuit boards, conductive wires, and electronic components. These components generate high-frequency electromagnetic waves during normal operation. These electromagnetic waves can interfere with electromagnetic waves generated by other electronic components and can also radiate into the outside world, potentially harming the human body. To reduce the interference and radiation caused by these electromagnetic waves, a shielding enclosure is usually designed to house these electronic components, thereby shielding them from the electromagnetic waves they generate.

[0003] Traditional shielding covers are usually installed on shielding frames using screws. When it is necessary to replace electronic components or perform repairs, the disassembly process of traditional shielding covers fixed with screws is usually quite cumbersome. If the operation is not done properly, it may cause the shielding cover to deform or even be damaged, affecting subsequent use. In order to address the above problems, we have introduced an electromagnetic interference-enhanced shielding cover. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0025] The electromagnetic interference-enhanced shielding cover disclosed in this utility model is mainly used in shielding cover applications.

[0026] Reference Figures 1 to 6 An electromagnetic interference-resistant enhanced shielding cover includes: a shielding frame 1, a shielding cover 2 on the top of the shielding frame 1, a hinge between the shielding frame 1 and one side of the shielding cover 2, a locking assembly inside the shielding frame 1 for fixing the shielding cover 2, and an anti-touch assembly on one side of the shielding frame 1.

[0027] The locking assembly includes a groove 3, which is formed inside the shielding frame 1. A pressing plate 4 is provided inside the groove 3. Two mounting rods 5 are fixedly connected to one side of the pressing plate 4. The outer sides of the two mounting rods 5 are slidably connected to the inside of the shielding frame 1. One end of the mounting rod 5 extends into the inside of the shielding frame 1 and is fixedly connected to a connecting plate 6. A fixing plate 7 is fixedly connected to the top of the connecting plate 6.

[0028] The bottom of the shielding cover 2 is provided with a fixing groove 8, and the bottom of the fixing plate 7 abuts against the bottom of the inner wall of the fixing groove 8;

[0029] A connecting rod 9 is fixedly connected to one side of the connecting plate 6. Two limiting rings 10 are fixedly connected to the outer side of the connecting rod 9. A fixing block 11 is fixedly connected to one side of the inner wall of the shielding frame 1. Rubber bands 12 are fixedly connected at equal intervals inside the fixing block 11. The outer side of the rubber bands 12 abuts against the outer side of the connecting rod 9.

[0030] The anti-touch component includes two mounting blocks 13, both of which are fixedly connected to one side of the shielding frame 1. A movable groove 14 is provided on one side of the mounting block 13, and a baffle 15 is slidably connected inside the movable groove 14.

[0031] A plate 16 is fixedly connected to one side of the baffle 15. A slot is provided on one side of the inner wall of the movable groove 14. The outer side of the plate 16 is slidably connected to the inside of the slot. Two rubber pads 17 are fixedly connected to one side of the baffle 15. Protrusions 18 are fixedly connected at equal intervals to one side of the baffle 15.

[0032] In the above technical solution, considering that traditional shielding covers are usually installed on shielding frames using screws, the disassembly process of traditional screw-fixed shielding covers is usually cumbersome when replacing electronic components or performing repairs. Improper operation may lead to deformation or even damage of the shielding cover, affecting subsequent use. To solve this problem, the specific operation is as follows: Using locking components and anti-contact components, the shielding frame 1 is fitted onto the electronic component through the bottom opening and installed on the equipment using screws. This covers the electronic component. Then, the shielding cover 2 is placed on top, and the corner of its fixing groove 8 contacts the top inclined surface of the fixing plate 7. Under pressure, the fixing plate 7 will be pushed open, and the pressing plate 4, mounting rod 5, connecting plate 6, connecting rod 9 and limiting ring 10 will all move. The rubber band 12 is stretched until the fixing plate 7 can enter the fixed plate. In the fixed slot 8, the shielding cover 2 and the shielding frame 1 can be completely closed. Under the elasticity of the rubber band 12, the pressing plate 4, the mounting rod 5, the connecting plate 6, the connecting rod 9 and the limiting ring 10 are driven to reset, so that one end of the fixing plate 7 abuts against the inside of the fixed slot 8, thereby fixing the shielding cover 2. When it is necessary to replace electronic components or perform maintenance, simply press the baffle 15 to compress the rubber pad 17, and the insert plate 16 is disengaged from the slot. Push the baffle 15 down to the bottom, and the pressing plate 4 is fully exposed. Then press the pressing plate 4, and the pressing plate 4, the mounting rod 5, the connecting plate 6, the connecting rod 9 and the limiting ring 10 move again until the fixing plate 7 can be misaligned with the fixed slot 8. Then open the shielding cover 2 to replace electronic components or perform maintenance. After maintenance, cover the shielding cover 2, and then press the baffle 15 and push it up to let the insert plate 16 enter the slot. By utilizing the fixing plate 7 and elastic rubber band 12 in the locking assembly, the shielding cover 2 can be opened and closed quickly, eliminating the tedious screw disassembly and assembly steps and greatly shortening maintenance time. By utilizing the baffle 15 and insert plate 16, the shielding cover 2 can block the pressing plate 4 after being closed, preventing accidental opening or loosening and ensuring the continuity of electromagnetic shielding effect.

[0033] Reference Figures 1 to 6 In a preferred embodiment, the surfaces of the shielding frame 1 and the shielding cover 2 are provided with a silver plating layer; covering the surfaces of the shielding frame 1 and the shielding cover 2 with a layer of silver can improve conductivity and corrosion resistance, and further enhance the shielding effect.

[0034] Working principle: In use, the shielding frame 1 is placed over the electronic component through the bottom opening and installed on the equipment with screws, thus covering the electronic component. Then, the shielding cover 2 is placed on top, with the corner of its fixing groove 8 contacting the top inclined surface of the fixing plate 7. Under pressure, the fixing plate 7 is pushed open, causing the pressing plate 4, mounting rod 5, connecting plate 6, connecting rod 9, and limiting ring 10 to move. The rubber band 12 is stretched until the fixing plate 7 can enter the fixing groove 8, and the shielding cover 2 and shielding frame 1 can be completely closed. Under the elasticity of the rubber band 12, the pressing plate 4, mounting rod 5, connecting plate 6, connecting rod 9, and limiting ring 10 are reset, allowing one end of the fixing plate 7 to rest against the fixing groove 8. Inside, the shield 2 is fixed in place. When it is necessary to replace electronic components or perform maintenance, simply press the baffle 15 to compress the rubber pad 17, causing the insert plate 16 to exit the slot. Push the baffle 15 down to the bottom, fully exposing the pressing plate 4. Then press the pressing plate 4, and the pressing plate 4, mounting rod 5, connecting plate 6, connecting rod 9, and limiting ring 10 will move again until the fixing plate 7 can be misaligned with the fixing slot 8. Then open the shield 2 to replace electronic components or perform maintenance. After maintenance, cover the shield 2, and then press the baffle 15 and push it upward to allow the insert plate 16 to enter the slot.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
