Technical Field

[0002] Circuit boards with multi-layer connection structures are usually called multi-layer circuit boards or multi-layer circuit boards. This type of circuit board is made up of multiple single-layer circuit boards connected by a certain number of internal layers, and its internal structure is invisible from the outside. The multi-layer circuit board consists of alternating conductive layers and insulating layers, and circuits on different layers can be interconnected, thus supporting complex circuit designs.

[0003] When installing the existing multi-layer circuit board, it is placed on the mounting frame like an ordinary circuit board, and the screws pass through the mounting holes on the multi-layer circuit board, and the ends of the screws are connected to the screw holes on the mounting frame, so as to fix the multi-layer circuit board. However, when installing the existing multi-layer circuit board, it often directly contacts the mounting frame, resulting in a small gap between the multi-layer circuit board and the mounting frame, which is not conducive to heat dissipation. After long-term use, the multi-layer circuit board has a high temperature and is easy to be damaged. When installing the multi-layer circuit board, it is necessary to use tools to rotate multiple screws, resulting in time-consuming and labor-intensive installation of the multi-layer circuit board. When the screws are rotated excessively, they exert a large force on the multi-layer circuit board, which easily causes damage to the multi-layer circuit board. At the same time, it is not conducive to the rapid disassembly of the multi-layer circuit board, and the operation is not convenient. Utility Model Content

At the same time, installation and disassembly are extremely convenient, which facilitates the rapid disassembly and replacement of the damaged circuit board body 1, and is highly convenient to use.

[0023] When installing the multi-layer circuit board, first fix the mounting structure 3 to a suitable place, and then install the circuit board body 1 onto the mounting structure 3. The components in the mounting structure 3 pass through the circular holes 2 on the circuit board body 1, thereby ensuring the stable installation of the circuit board body 1. At this time, there is a large space under the circuit board body 1, which is convenient for the multi-layer circuit board to dissipate heat when in use, and prevent the electronic components 4 from being overheated and damaged.

[0024] Through the above embodiment, the mounting structure 3 includes a mounting base plate 301, a socket 303, a fixing frame 305, a movable rod 306, a plug rod 307, a tightening assembly 308 and a tightening spring 309, the mounting base plate 301 is fixedly connected to the socket 303, the fixing frame 305 is fixed on the mounting base plate 301, the movable rod 306 is connected to the plug rod 307, and the movable rod 306 is arranged on the fixing frame 305, the lower end of the plug rod 307 is connected in the socket 303, the tightening assembly 308 is installed on the plug rod 307 at a position close to the movable rod 306, the tightening spring 309 is sleeved on the movable rod 306, the mounting structure 3 also includes a waist-shaped hole 302, a limiting slot 304, a top limiting plate 310 and an operating ball 311, the waist-shaped hole 302 is opened on the mounting base plate 301, the limiting slot 304 is arranged in the socket 303, a through hole is opened on the fixing frame 305, and the movable rod 306 is arranged on the fixing frame 305. The rod 306 is located in the through hole on the fixing frame 305, the lower end of the plug rod 307 is inserted into the limiting slot 304 on the socket 303, the upper end of the tightening spring 309 contacts the fixing frame 305, and the lower end of the tightening spring 309 is in contact with the tightening assembly 308, the top limiting plate 310 is fixed to the upper end of the movable rod 306, the operating ball 311 is installed on the top limiting plate 310, and the tightening assembly 308 includes an external thread 3081, The clamping plate 3082, the threaded hole 3083, the rubber pad 3084 and the through hole 3085, the external thread 3081 is set on the insertion rod 307, the threaded hole 3083 is opened on the clamping plate 3082, and the clamping plate 3082 is connected with the external thread 3081 on the insertion rod 307 through the threaded hole 3083, the through hole 3085 is opened on the rubber pad 3084, and the rubber pad 3084 and the clamping plate 3082 are fixed together by glue.

[0025] When assembling the mounting structure 3, the lower end of the movable rod 306 passes through the through hole on the fixing frame 305, and a clamping spring 309 is sleeved on the lower end of the movable rod 306. Then, the clamping plate 3082 is installed on the insertion rod 307 by means of the threaded connection between the threaded hole 3083 and the external thread 3081. The rubber pad 3084 with the through hole 3085 is connected to the lower end of the clamping plate 3082 by glue. When the mounting structure 3 is assembled, the mounting base plate 301 is placed in a suitable position, and the screws are passed through the waist-shaped holes 302 for installation and fixing, thereby completing the installation of the entire mounting structure 3. When installing a multi-layer circuit board, the movable rod 306 is lifted by the operating ball 311 on the top limiting plate 310. The movable rod 306 rises with the insertion rod 307, and the clamping assembly 308 rises together and compresses the clamping spring 309 until the insertion rod 307 moves out of the limiting slot 304 to make way. , then put the circuit board body 1 on the socket 303, ensure that the limiting slot 304 is aligned with the circular hole 2, and after releasing the operating ball 311, the movable rod 306, the plug rod 307 and other structures descend, and the plug rod 307 passes through the circular hole 2 and is inserted into the limiting slot 304, and the tightening component 308 is pressed on the circuit board body 1. Under the elastic action of the tightening spring 309, the rubber pad 3084 on the lower surface of the tightening plate 3082 exerts a large pressing force on the circuit board body 1, thereby ensuring the stability of the circuit board body 1 after installation. During the tightening process, the rubber pad 3084 plays a buffering and protective role to prevent the circuit board body 1 from being damaged due to excessive impact force. When the circuit board body 1 is installed, it can be used. When the circuit board body 1 needs to be disassembled for replacement, it is only necessary to lift the movable rod 306 and the plug rod 307 to make way by operating the ball 311, and then take away the circuit board body 1 for replacement.

[0026] Specifically, by setting the mounting structure 3 at the circular hole 2, when installing the multi-layer circuit board, the circuit board body 1 is directly placed on the socket 303, and the multi-layer circuit board is fixed by using the movable rod 306, the plug rod 307, the clamping assembly 308 and the clamping spring 309, so that the multi-layer circuit board can be installed quickly without causing damage to the multi-layer circuit board. At the same time, the circuit board body 1 is suspended through the plug socket 303, which can improve the heat dissipation effect of the multi-layer circuit board when in use. When the multi-layer circuit board is damaged, the movable rod 306 and other structures can be quickly lifted up to make way, which is convenient for quickly disassembling the multi-layer circuit board for replacement. The clamping assembly 308 is threadedly connected to the plug rod 307, which can be used for relative height adjustment and quick disassembly to replace the clamping spring 309. It has a simple structure and high flexibility and adaptability.
