An anti-vibration pcb board

Abstract

The invention discloses an anti-vibration PCB board, which includes a carrier board, a PCB board, a sleeve rod, a connecting shaft, a fixed shaft, a screw, a pressure plate, a guide plate, a shrapnel, a sleeve shaft, a spring, a movable shaft, a foot, a limit plate, Teeth and bumpers. The invention is simple in structure and easy to operate. By using the feet to support the carrier board, it is convenient to improve the stability when the PCB board is installed, and improves the anti-vibration effect when the PCB board is fixed, which is beneficial to the stable use of the PCB board; the invention uses screws and The design of the sleeve rod is not only convenient for fixing the PCB board, but also helps to improve the vibration reduction performance of the PCB board, avoiding the damage of the PCB board when it is dropped or collided, avoiding the problem of loose screws caused by long-term use, and improving the PCB board. The protection performance of the board; the present invention further improves the anti-vibration performance of the PCB board through the design of the buffer pad, and the elastic deformation of the buffer pad is beneficial to limit the pressure plate, which improves the stability of the PCB board when it is installed, and improves the stability of the PCB board. service life.

Description

technical field [0001] The invention relates to a PCB board, in particular to an anti-vibration PCB board, belonging to the technical field of PCB board application. Background technique [0002] PCB board is printed circuit board, also known as printed circuit board, is the provider of electrical connection of electronic components, its development has been for many years, its design is mainly layout design; Reduce wiring and assembly errors, improve automation level and production labor rate, according to the number of layers of circuit boards, it can be divided into single-panel, double-panel, four-layer board, six-layer board and other multi-layer circuit boards, which appear in printed circuit boards In the past, the interconnection between electronic components relied on the direct connection of wires to form a complete circuit. In contemporary times, circuit panels only exist as effective experimental tools, and printed circuit boards have become an absolute dominance...

AI Technical Summary

Problems solved by technology

[0003] The current PCB boards are divided into single-sided boards, double-sided boards and multi-layer boards, etc., which have the advantages of small size and light weight. For PCB boards, the PCB board is usually fixed in the device to play the role of an integrated circuit. When in use, It is not conducive to the fixing of the PCB board, and it is easy to cause the PCB board to vibrate when it falls or collides, and it is easy to cause damage to the PCB board, which affects the use effect of the PCB board
