Description

Technical Field

[0001] This utility model relates to the field of circuit board technology, specifically to a multilayer circuit board. Background Technology

[0002] In the rapid development of modern electronic devices, multilayer circuit boards have been widely used in various electronic products due to their significant advantages such as high integration and space saving.

[0003] A search revealed CN218735172U, a multilayer circuit board comprising a multilayer circuit board body, a mounting plate disposed below it, and a heat sink disposed above the multilayer circuit board body. It also includes a fixing member disposed between the heat sink and the multilayer circuit board body for fixing the multilayer circuit board body. This invention, through the cooperation of the various components, allows the multilayer circuit board body to be installed by moving a trapezoidal block via a connecting rod fixedly connected to the lower surface of the heat sink, thus engaging it with a trapezoidal groove. This achieves the installation and fixing of the multilayer circuit board and facilitates subsequent disassembly.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Please see Figure 1-4 As shown, this utility model is a multilayer circuit board, comprising:

[0031] Circuit board housing 100;

[0032] The adjustment component includes a base plate 200, a top plate 201, a guide rod 202, a horizontal plate 203, and a guide ring 204. The base plate 200 is located below the circuit board housing 100, the top plate 201 is located above the circuit board housing 100, the guide rod 202 is fixed to the top of the base plate 200, the horizontal plate 203 is disposed on both sides of the outer surface of the circuit board housing 100, and the guide ring 204 is fixed to the top and bottom of the horizontal plate 203 and is movably connected to the outer surface of the guide rod 202.

[0033] The guide ring 204 is fitted and movable on the outer surface of the guide rod 202, so that multiple circuit board housings 100 can be installed between the base plate 200 and the top plate 201. By moving the guide ring 204 outside the guide rod 202, the spacing between the circuit boards can be flexibly adjusted according to actual needs. For some equipment with high heat dissipation requirements, the heat dissipation efficiency can be improved by increasing the spacing between the circuit board housings 100, while for equipment with more compact space, the spacing between the circuit board housings 100 can be reduced to achieve more efficient space utilization.

[0034] A fastening ring 205 is threaded onto the upper part of the outer surface of the guide rod 202, and the fastening ring 205 is pressed against the top and bottom of the top plate 201;

[0035] After the top plate 201 is installed on the upper part of the outer surface of the guide rod 202, the fastening ring 205 is fixed by threads and blocks the top and bottom of the top plate 201 to fix the top plate 201.

[0036] It also includes a fixing component, which includes a side plate 301, an internal threaded ring 302, a threaded rod 303 and a handle 304. The side plate 301 is welded to one side of the outer surface of the horizontal plate 203, the internal threaded ring 302 is fixed to the outside of the side plate 301, the threaded rod 303 is threaded to the middle of the internal threaded ring 302, and the handle 304 is rotatably connected to the outside of the threaded rod 303.

[0037] Rotating the handle 304 drives the threaded rod 303 to rotate, applying pressure to the rubber block 300, which is then clamped to the outside of the guide rod 202, thus fixing the position of the circuit board housing 100 after it has moved.

[0038] A rubber block 300 is bonded to the other side of the outer surface of the threaded rod 303, and the rubber block 300 is clamped and connected to one side of the outer surface of the guide rod 202.

[0039] Working principle: First, the guide ring 204 is sleeved on the outer surface of the guide rod 202 and can move flexibly on the guide rod 202. In practical applications, according to the specific requirements of different electronic devices, the smooth sliding of the guide ring 204 on the outside of the guide rod 202 allows for flexible adjustment of the spacing between the circuit board housings 100. For devices with high heat dissipation requirements, increasing the spacing between the circuit board housings 100 allows the heat generated during operation to be dissipated more efficiently, effectively preventing problems such as performance degradation or even damage to electronic components due to heat accumulation, and ensuring stable operation of the device. For devices with more compact space, reducing the spacing between the circuit board housings 100 allows for more efficient layout within a limited space, improving device integration. After adjusting the spacing of the circuit board housing 100, the top plate 201 is installed on the upper part of the outer surface of the guide rod 202. The fastening ring 205 is tightened, and the fastening ring 205 will block the top and bottom of the top plate 201 respectively, forming a stable limiting structure, thereby firmly fixing the top plate 201 to the guide rod 202. Then, the handle 304 is turned to drive the threaded rod 303 to rotate. As the threaded rod 303 rotates, it will apply pressure to the rubber block 300, causing the rubber block 300 to deform and tightly clamp to the outside of the guide rod 202. The friction between the rubber block 300 and the guide rod 202 can effectively prevent the circuit board housing 100 from moving, thereby firmly locking the circuit board housing 100 in the adjusted position, ensuring the stability and reliability of the multilayer circuit board during long-term use.

[0040] Please see Figure 1 , Figure 3 , Figure 5 As shown, this embodiment, based on the above embodiment, further includes:

[0041] An insulating component, comprising an insulating plate 400 and a clamping frame 403, wherein the insulating plate 400 surrounds the bottom of the circuit board housing 100, and the clamping frame 403 is fixed to both ends of the outer surface of the insulating plate 400 and clamps and connects to both ends of the outer surface of the circuit board housing 100.

[0042] The circuit board housing 100 generates electromagnetic signals during operation. The insulating plate 400 installed at the bottom has good electromagnetic shielding performance and can effectively isolate the electromagnetic fields generated by each circuit board.

[0043] The top of the clamping frame 403 is provided with an inner groove 404, and the two ends of the circuit board housing 100 are fixed with positioning rods 401, which are embedded in the inner groove 404.

[0044] The clamping frame 403 is clamped on the outside of the circuit board housing 100 to install the insulating board 400.

[0045] A locking ring 402 is fastened to the outer surface of the positioning rod 401, and the locking ring 402 is attached to the outer surface of the clamping frame 403;

[0046] The positioning rod 401 is embedded inside the inner groove 404, while the locking ring 402 is fastened to the outside of the positioning rod 401 to fix the positioning rod 401.

[0047] Working principle: The clamping frame 403 is designed to fit the shape of the circuit board housing 100, tightly clamping the outside of the circuit board housing 100, so that the insulating plate 400 is installed at the bottom of the circuit board housing 100. The inner side of the clamping frame 403 is provided with an inner groove 404, and one end of the positioning rod 401 is precisely embedded in the inner groove 404. The locking ring 402 is screwed on the outside of the positioning rod 401. Through the threaded engagement between the locking ring 402 and the positioning rod 401, sufficient fastening force is generated to firmly fix the positioning rod 401 on the clamping frame 403, thereby achieving a stable installation of the insulating plate 400. When the circuit board housing 100 is put into operation, the internal electronic components will continuously generate electromagnetic signals. The insulating plate 400 installed at the bottom of the circuit board housing 100 has good electromagnetic shielding performance and can effectively isolate the electromagnetic fields generated by each circuit board.
