Description

Technical Field

[0001] The utility model relates to the technical field of multi-layer PCB boards, in particular to a multi-layer PCB board. Background Art

[0002] A multi-layer PCB is a complex printed circuit board with multiple levels of circuits and electrical connections. Usually, it consists of at least 3 layers of copper foil and 2 layers of insulation, where the copper foil is a conductor layer for transmitting current, and the insulation layer is used to isolate different layers of copper foil to prevent short circuits between them.

[0003] Multilayer PCBs use perforations to connect different layers of copper foil to form electrical connections. These perforations allow circuits to transmit signals and currents between different layers, thereby realizing complex circuit functions. Compared with single-layer and double-layer PCBs, multilayer PCBs have higher line density and better electrical performance. They can reduce electromagnetic interference, improve signal integrity, and also improve circuit reliability and stability. In addition, multilayer PCBs also have better heat dissipation performance, which can help electronic devices dissipate heat better, improve work efficiency and lifespan.

[0004] Multilayer PCBs are usually used in high-density electronic devices, such as computers, communication equipment, mobile devices, etc., because they can accommodate more circuits and components in a limited space. At present, the existing multilayer PCBs are not convenient to install and disassemble, and do not have a heat dissipation mechanism, which reduces the practicality of the multilayer PCBs.

The number of the mounting block 4 is two, and the shape of the mounting block 4 is square. The mounting block 4 is provided to facilitate the installation of the multi-layer PCB board body 6. The same multi-layer PCB board body 6 is fixedly installed on one side of the two mounting blocks 4. A fixing mechanism is provided on the frame 5. The fixing mechanism is provided to facilitate the disassembly of the multi-layer PCB board body 6, which is conducive to the maintenance of the multi-layer PCB board body 6. A heat dissipation mechanism is provided on the mounting seat 1. The heat dissipation mechanism is provided to dissipate the multi-layer PCB board body 6 when the multi-layer PCB board body 6 is working, which is conducive to the long-term operation of the multi-layer PCB board body 6.

[0022] In detail, the installation mechanism includes a through slot 31, which is opened on the mounting seat 1. The through slot 31 is a square slot. The through slot 31 is provided to facilitate the installation of the rotating rod 35. There are two through slots 31, and the two through slots 31 are symmetrically arranged. The inner wall of the through slot 31 is rotatably connected to the rotating rod 35, and one end of the rotating rod 35 passes through the mounting seat 1.

[0023] Furthermore, the rotating rod 35 is provided with positive and negative threads. By providing the rotating rod 35 with positive and negative threads, it is convenient to drive the receiving blocks 32 on both sides to move. The receiving blocks 32 are threadedly connected to the rotating rod 35, and the receiving blocks 32 are provided with mounting holes 33. The provision of the mounting holes 33 facilitates the insertion and installation of the bolts.

[0024] Furthermore, a limiting slot 34 is provided on the side of the mounting seat 1, and the limiting slot 34 is connected to the through slot 31. The setting of the limiting slot 34 serves the purpose of receiving the sliding of the square block 36. There are two limiting slots 34, and the two limiting slots 34 are symmetrically arranged. A square block 36 is slidably arranged on the inner wall of the limiting slot 34. The square block 36 is fixedly connected to the receiving block 32, and the fixed connection can be replaced by bolts or welding. By providing the square block 36 and the limiting slot 34, when the rotating rod 35 drives the receiving block 32 to move, the movement of the receiving block 32 is limited, which is conducive to the receiving blocks 32 on both sides to slide toward or in the opposite direction.

[0025] In more detail, the fixing mechanism includes a spring 22, which is fixedly mounted on the top of the frame 5. The fixed connection can be replaced by welding. The spring 22 is provided to facilitate the installation of the latch 21. There are two springs 22, which are symmetrically arranged.

[0026] In general, a pin 21 is fixedly installed at one end of the spring 22, and the fixed connection can be replaced by welding. The cross-sectional shape of the pin 21 is T-shaped. The provision of the pin 21 facilitates plugging into the slot 23. There are two pins 21, and the two pins 21 are symmetrically arranged. One end of the pin 21 passes through the inner wall of the frame 5. A slot 23 is provided on the mounting block 4. The shape of the slot 23 is a cylindrical groove.

[0027] Finally, the heat dissipation mechanism includes a bracket 72, which is fixedly installed on the mounting base 1, and the fixed connection can be replaced by bolts or welding.

[0028] Working mode: During operation, when the multi-layer PCB board is installed, according to the installation surface conditions, the rotating rod 35 is rotated. The rotating rod 35 is provided with positive and negative threads, which will drive the receiving blocks 32 on both sides to move. Under the limiting action of the square block 36 and the limiting slide groove 34, the receiving blocks 32 on both sides will move towards or in the opposite direction until the installation through hole 33 on the receiving block 32 moves to a suitable position, and cooperates with the bolts to facilitate the installation of the multi-layer PCB board.

[0029] When the multi-layer PCB body 6 is working, the fan 71 is started. The fan 71 has a blowing function, which will blow air to dissipate the multi-layer PCB body 6, which is beneficial to the long-term operation of the multi-layer PCB body 6. When the multi-layer PCB body 6 needs to be disassembled for inspection, the latches 21 on both sides are pulled, and one end of the latch 21 is pulled away from the slot 23, so that the mounting block 4 can be taken out from the frame 5, thereby achieving the purpose of disassembling the multi-layer PCB body 6, which is beneficial to the inspection of the multi-layer PCB body 6.
