[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3 This utility model provides a technical solution:

[0022] A plug-in multilayer circuit board includes a socket 1 and a multilayer circuit board body 6. The top surface of the socket 1 has three sets of slots 2 for the multilayer circuit board body 6 to be inserted, and guide grooves 3 are fixedly installed at both ends of the top of the slots 2. A bracket 4 is installed on the top of the socket 1, and the slots 2 and guide grooves 3 are located in the inner cavity of the bracket 4. Limiting seats 5 are fixedly installed at the center of both sides of the inner side of the bracket 4. The inner surface of the limiting seats 5 has three sets of limiting grooves 501 for limiting the multilayer circuit board body 6. The multilayer circuit board body 6 is engaged with the inside of the slot 2 through one end of the limiting grooves 501 and guide grooves 3.

[0023] This utility model uses a combination of components such as a socket 1, a slot 2, a guide groove 3, a bracket 4, a limit seat 5, a limit groove 501, and a multi-layer circuit board body 6 to facilitate the snap-fit ​​fixing of the multi-layer circuit board body 6, thereby improving the efficiency of disassembly, maintenance, and installation. Furthermore, the combination of the guide groove 3 and the limit groove 501 further enhances the stability of the snap-fit ​​of the multi-layer circuit board body 6.

[0024] Furthermore, by hand, the multi-layer circuit board body 6 is picked up and passed through the limiting groove 501 and the guide groove 3 on both sides in sequence. Then, it is inserted into the slot 2 and fixed in place. This not only fixes the multi-layer circuit board body 6 in place, but also limits and blocks its movement, thereby improving its stability during installation. Conversely, by operating in the opposite direction, the multi-layer circuit board body 6 can be removed from the socket 1, enabling quick disassembly, inspection, and replacement of the multi-layer circuit board body 6.

[0025] The top of the bracket 4 is provided with a dustproof assembly for covering the multi-layer circuit board body 6 to prevent dust. The dustproof assembly includes a dustproof plate 7, a shield 701 and a vent 702. The shield 701 is installed on the front and back ends of the bottom of the dustproof plate 7, and the surface of the shield 701 has several sets of vents 702 for ventilation.

[0026] This utility model uses components such as a dustproof plate 7, a shielding plate 701, and a ventilation opening 702 to provide dust protection for the top of the multilayer circuit board body 6, thereby reducing the likelihood of dust accumulation on the multilayer circuit board body 6 and improving its service life and performance.

[0027] The dustproof plate 7 has support rods 8 fixedly installed around its bottom perimeter, and locking posts 801 are fixedly installed at the bottom of the support rods 8. The top perimeter of the bracket 4 has grooves 802, and locking posts 801 are engaged inside the grooves 802, with the grooves 802 and locking posts 801 fitting together. By providing locking posts 801 and grooves 802, the dustproof plate 7 can be easily disassembled and installed, and the multi-layer circuit board body 6 on the socket 1 can also be easily removed.

[0028] Furthermore, by hand, the dustproof plate 7 is picked up and the support rods 8 around its bottom are aligned with the corresponding column grooves 802 around the top of the bracket 4. Then, the locking posts 801 at the bottom of the support rods 8 are inserted into the column grooves 802 to lock the dustproof plate 7 in place. At the same time, the shielding plates 701 on the front and back of the bottom of the dustproof plate 7 cover the outer ends of the multilayer circuit board body 6 and the bracket 4, thereby facilitating the dustproof effect of the multilayer circuit board body 6.

[0029] The multilayer circuit board body 6 is configured with three layers, and the layers are fixed together around the perimeter by connecting rods 601 and fasteners 602. One end of the connecting rod 601 passes through the multilayer circuit board body 6 and engages with the fastener 602. By using the connecting rod 601 and the fastener 602, the multilayer circuit board body 6 can be easily disassembled and replaced.
