Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, and in particular to a multilayer circuit board capable of preventing the circuit board from moving and colliding. Background Art

[0002] The names of circuit boards include: circuit board, PCB board, aluminum substrate, high-frequency board, PCB, ultra-thin circuit board, ultra-thin circuit board, printed circuit board, etc. Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout; with the rapid development of electronic technology, the requirements for electronic products are getting higher and higher, the functions are increasing, and the integration of chips is getting higher and higher. Correspondingly, the design requirements for circuit boards are also getting higher and higher. The existing multi-layer circuit boards that can prevent movement and collision are not convenient for installing circuit boards of different sizes, and have poor versatility. In addition, the corners of the multi-layer circuit boards are easily collided during movement, which causes damage to the circuit boards.

[0003] After searching, the Chinese patent announcement number is CN215499730U, which discloses a multi-layer circuit board that can prevent movement and collision. In this patent, when the first rotating knob is rotated to rotate forward or reverse, the right threaded rod and the left threaded rod are driven to rotate forward or reverse, thereby driving the symmetrical moving plates on the right threaded rod and the left threaded rod to move left or right, so that the spacing between the lower clamping plate and the upper clamping plate symmetrical in the horizontal direction can be adjusted, so that circuit boards of different lengths can be clamped and fixed; by rotating the second rotating knob to drive the support rod to rotate, the upper clamping plate located in the threaded area moves upward or downward, thereby adjusting the spacing between the lower clamping plate and the upper clamping plate, so that circuit boards of different thicknesses can be clamped and fixed, solving the problem of inconvenience in installing and disassembling circuit boards of different sizes and thicknesses, and having strong versatility, convenience of use, and strong practicality;

[0004] However, during use of the above device, because the support rod is fixedly connected to the lower clamping plate, and the support rod is rotatably connected to the upper clamping plate through a thread, when in use, the support rod rotates to drive the upper clamping plate to move up and down, and cooperates with the lower clamping plate to fix the circuit board. However, the rotation of the support rod will also drive the fixedly connected lower clamping plate to rotate, thereby affecting the fixation of the circuit board, and thus cannot effectively fix circuit boards of different thicknesses. At the same time, the method of fixing circuit boards of different sizes by rotation and other methods of the above device is too cumbersome and the fixing effect is poor. Utility Model Content
