Buffering and vibration isolation structure of annular circuit board

Abstract

The invention relates to a buffering and vibration isolation structure of an annular circuit board. The buffering and vibration isolation structure comprises n baffle plates, n rubber rings, and a box body pedestal. After the first rubber ring is embedded into the periphery of a first circuit board, the first circuit board is arranged at a first step of the box body pedestal and the first baffle plate is fixedly connected to a second step of the box body pedestal, wherein the lower surface of the first baffle plate compresses the first rubber ring; after the second rubber ring is embedded into the periphery of a second circuit board, the second circuit board is arranged at the upper surface of the first baffle plate and the second baffle plate is fixedly connected to a third step of the box body pedestal, wherein the lower surface of the second baffle plate compresses the second rubber ring; after the third rubber ring is embedded into the periphery of a third circuit board, the third circuit board is arranged at the upper surface of the second baffle plate, and so on; and then the nth baffle plate is fixedly connected with the upper end surface of the box body pedestal and compresses the nth rubber ring. According to the buffering and vibration isolation structure, a buffering and vibration isolation problem of a circuit board in a narrow and small mounting space can be solved; the good buffering and vibration isolation effect of a circuit board can be guaranteed; and rapid installation and dismounting of the circuit board can be realized.

Description

technical field [0001] The invention relates to a buffer and vibration isolation design structure of a circuit board in a product with a very harsh mechanical environment, in particular to a ring circuit board buffer vibration isolation structure. Background technique [0002] For various types of equipment in certain application fields, the application environment is generally relatively harsh, usually accompanied by a large number of vibrations and shocks, low-frequency bands, high-frequency bands, explosion shocks, etc. In this case, in order to ensure the harsh mechanical In order for the circuit to work normally under environmental conditions, it is generally necessary to use a vibration isolator on the circuit board to reduce the impact of the external mechanical environment on the normal operation of the circuit. At present, the commonly used circuit board buffer vibration isolation measures mainly use vibration isolators, such as "T" type vibration isolators. This vi...

AI Technical Summary

Problems solved by technology

At present, the commonly used buffer vibration isolation measures for circuit boards mainly use vibration isolators, such as "T" type vibration isolators. This vibration isolator has good vibration isolation effect, but requires a large installation space. The vibration isolator circuit board usually adopts multi-point installation. The disadvantage of multi-point installation is that it is easy to cause the amplification of external excitation. Circuit board damage and failure due to local excitation amplification
