Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic shielding technology, and in particular to a shielding assembly. Background Technology
[0002] Shielding assemblies are key components used in electronic devices to reduce electromagnetic interference. Shielding covers can be made of different structures depending on the object and requirements: for example, copper-aluminum solid shells are used to protect against interference from small instruments or devices; magnetic materials such as iron or beryllium-molybdenum alloys are used to make shells for low-frequency electromagnetic interference; and superconducting material shielding covers are used to protect against interference from precision electromagnetic measurements at low temperatures. These are common in daily life.
[0003] Existing technologies, such as the utility model patent with publication number CN221807568U, disclose an electronic shielding cover assembly. This patent includes a lower cover, an upper cover, and an adjusting screw. The lower cover has mounting holes at its four corners, and lower columns are evenly fixed to its sides. A through hole is formed between two sets of lower columns. An internal locking block is fixed to the lower part of each upper column. Heat dissipation strips are provided on the upper surface of the upper cover. Upper connecting blocks are fixed to the lower corners of the upper cover, and the adjusting screw is connected to the lower part of each upper connecting block. An internal locking groove is formed inside the surface of each lower column. This electronic shielding cover assembly allows the adjusting screw to move the upper connecting blocks upwards, enabling the corner locking blocks below the upper cover to engage and slide within the internal locking grooves of the lower column and the internal locking blocks below the upper column. This allows adjustment of the height between the lower and upper covers, thus adjusting the depth of the device and improving its usability.
[0004] In daily use, it has been found that when using shielding covers for protection, there will be situations where it is necessary to install the shielding cover on the surface of electronic components. The shielding cover is used to protect the electronic components. However, the installation of ordinary shielding covers is relatively cumbersome and it is easy to encounter problems with the installation limit of the shielding cover. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies where shielding covers are installed on the surface of electronic components to protect them. However, conventional shielding covers are often cumbersome to install and have inconvenient installation limits.
[0006] To solve the above-mentioned technical problems, this utility model provides a shielding cover assembly, including: a mounting plate, on the surface of which electronic components are disposed, and a shielding cover body is mounted on the surface of the mounting plate corresponding to the positions of the electronic components. Mounting mechanisms are provided at both ends of the mounting plate corresponding to the shielding cover body. Each mounting mechanism includes a fixing frame, the bottom end of which is fixedly connected to the surface of the mounting plate. Connecting blocks are rotatably connected to both ends of the inner wall of the fixing frame. A common fixing ring slides through the inner walls of the two connecting blocks. Springs are fitted onto the arc surfaces of both ends of the fixing ring, and the two ends of the springs are fixedly connected to the connecting blocks and the fixing ring, respectively. A fixing block is fixedly connected to the surface of the shielding cover body at the position corresponding to the fixing ring. The cross-section of the fixing block is U-shaped. An extrusion column is fixedly connected to the arc surface of the fixing ring, and the arc surface of the extrusion column abuts against the inner wall of the fixing block.
[0007] The effect achieved by the above components is as follows: during the operation and use of electronic components, it is necessary to use the shielding cover body in the electronic equipment to reduce electromagnetic interference. At this time, in order to facilitate the installation and fixation of the shielding cover body, an installation mechanism can be used for auxiliary operation, which facilitates the replacement and limit protection of the position of the shielding cover body.
[0008] Preferably, a protective sleeve is fixedly connected to the arc surface of the extrusion column, and the surface of the protective sleeve is provided with anti-slip texture.
[0009] The effect achieved by the above components is that the protective sleeve on the surface of the extrusion column can effectively increase friction, making it easier to extrude and fix.
[0010] Preferably, a connecting plate is fixedly connected to the surface of the fixing ring, and a pressing rod is threaded through the surface of the connecting plate. A pressing pad is fixedly connected to one end of the pressing rod near the fixing block.
[0011] The effect achieved by the above components is that after the position of the fixed ring is stretched and limited by the spring, the position can be extended and retracted by the extrusion rod on the surface of the connecting plate, thereby limiting the movement distance of the fixed ring by the extrusion rod.
[0012] Preferably, a coil spring is fitted onto the arc surface of one end of the connecting block near the fixing frame, and the two ends of the coil spring are fixedly connected to the connecting block and the fixing frame, respectively.
[0013] The effect achieved by the above components is that the torsional force generated by the coil spring can compress and limit the position of the connecting block.
[0014] Preferably, limit holes are formed on the four corner surfaces of the shielding cover body, and limit posts are fixedly connected to the surface of the mounting plate at the positions corresponding to the limit holes, with the arc surface of the limit posts inserted into the inner wall of the limit holes.
[0015] The effect achieved by the above components is that the shielding cover body can be temporarily fixed and protected by the insertion and limiting between the limiting post and the limiting hole.
[0016] Preferably, a protective plate is fixedly connected to the upper surface of the shielding cover body, and the protective plate is a stainless steel plate.
[0017] The effect achieved by the above components is that the stainless steel protective plate fixed on the upper surface of the shielding cover can effectively reflect or absorb electromagnetic waves, thereby performing shielding operations.
[0018] Preferably, the fixing ring is a cemented carbide ring, and the cross-sectional dimensions of the fixing ring are adapted to the cross-sectional dimensions of the fixing block.
[0019] The effect achieved by the above components is that the fixed ring made of hard alloy can be used for a long time, avoiding deformation of the fixed ring, and can be matched and fixed with the inner wall of the fixed block.
[0020] Compared with related technologies, the shielding cover assembly provided by this utility model has the following beneficial effects:
[0021] This utility model provides a shielding cover assembly. By operating the installation mechanism, it achieves protection for electronic components. The shielding cover body is used for fixed and limited protection. During this process, the fixing ring inside the fixing frame, which slides through the connecting block, is engaged with the fixing block on the surface of the shielding cover body by means of the fixing brackets on both sides of the mounting plate. At the same time, the tensile force generated by the spring is used to squeeze and fix the position between the fixing ring and the fixing block, which effectively and conveniently limits the installation of the entire shielding cover body.

[0028] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0029] Please see Figures 1 to 4 The present invention provides a shielding assembly, comprising: a mounting plate 1, an electronic component 3 disposed on the surface of the mounting plate 1, a shielding body 2 mounted on the surface of the mounting plate 1 corresponding to the position of the electronic component 3, and mounting mechanisms 4 disposed on both ends of the surface of the mounting plate 1 corresponding to the positions of the shielding body 2.
[0030] In the embodiments of this utility model, please refer to Figure 2 , Figure 3 and Figure 4The installation mechanism 4 includes a fixing frame 401, the bottom end of which is fixedly connected to the surface of the mounting plate 1. Connecting blocks 408 are rotatably connected to both ends of the inner wall of the fixing frame 401. A single fixing ring 403 slides through the inner walls of the two connecting blocks 408. Springs 409 are fitted onto the arc surfaces of both ends of the fixing ring 403, and the two ends of the springs 409 are fixedly connected to the connecting blocks 408 and the fixing ring 403 respectively. A fixing block 402 is fixedly connected to the surface of the shielding cover body 2 at a position corresponding to the fixing ring 403. The fixing block 402 has a U-shaped cross-section. A pressing column 404 is fixedly connected to the arc surface of the fixing ring 403. The arc surface of the pressing column 404 abuts against the inner wall of the fixing block 402. A protective sleeve 405 is fixedly connected to the arc surface of the pressing column 404. The surface of the protective sleeve 405 has anti-slip textures. The fixing ring 403... A connecting plate 410 is fixedly connected to the surface of the shielding cover body 2. A pressing rod 411 is threaded through the surface of the connecting plate 410. A pressing pad 412 is fixedly connected to one end of the pressing rod 411 near the fixing block 402. A coil spring 413 is sleeved on the arc surface of the connecting block 408 near the fixing frame 401. The two ends of the coil spring 413 are fixedly connected to the connecting block 408 and the fixing frame 401 respectively. Limiting holes 406 are opened on the four corner surfaces of the shielding cover body 2. Limiting posts 407 are fixedly connected to the surface of the mounting plate 1 at the positions corresponding to the limiting holes 406. The arc surface of the limiting post 407 is inserted into the inner wall of the limiting hole 406. A protective plate 414 is fixedly connected to the upper surface of the shielding cover body 2.

[0031] The working principle of the shielding cover assembly provided by this utility model is as follows: In the process of electromagnetic interference shielding protection for electronic component 3, it is necessary to fix and limit the position of the shielding cover body 2 with the help of the mounting mechanism 4. At this time, the entire shielding cover body 2 is first inserted into the limiting post 407 fixed on the surface of the mounting plate 1 through the limiting hole 406, so that the shielding cover body 2 protects the electronic component 3. Then, the fixing ring 403 in the fixing bracket 401 at both ends of the mounting plate 1 is pulled, so that the fixing ring 403 slides along the inner wall of the connecting block 408. At the same time, the tension force generated by the spring 409 is used to squeeze and limit the position of the fixing ring 403. Then, the pressing post 404 at one end of the fixing ring 403 is locked and fixed with the inner wall of the connecting block 408. Finally, the pressing rod 411 threaded through the connecting plate 410 on the surface of the fixing ring 403 is rotated, so that the pressing rod 411 moves towards the fixing block 402, thereby preventing the entire fixing ring 403 from easily falling off and separating from the fixing block 402.
