Folding circuit board structure with buffer function

Abstract

The invention discloses a folding circuit board structure with a buffer function. The folding circuit board structure comprises a printed board, a flexible circuit board is fixedly arranged on the printed board, the flexible circuit board is folded into a bottom layer, a middle layer and an upper layer, the upper layer is connected with the middle layer through the bottom layer, one end of the bottom layer is connected with one end of the upper layer through a bending plate I, the other end of the upper layer is connected with the middle layer support through a buffer assembly I, the other end of the bottom layer is connected with one end of the middle layer through a bending plate II, the other end of the middle layer is connected with the bottom layer support through a buffer assembly II, and the bottom layer is fixedly arranged on the printed board. The flexible circuit board is folded into the bottom layer, the middle layer and the upper layer, the space of the circuit board is effectively saved, the purpose of miniaturization is achieved, and the buffer assembly I and the buffer assembly II are supported among the bottom layer, the middle layer and the upper layer, so the stability and vibration resistance of the layers are improved, the folding assembly process is simplified, and normal use of the circuit board is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of circuit boards, and in particular relates to a foldable circuit board structure with a buffer function. Background technique [0002] In order to make electronic information technology develop in the direction of high speed, multi-function, large capacity, small volume, thinner, and lighter weight, flexible circuit boards are currently used as circuit connections for components. Since the flexible circuit board has the characteristics of high wiring density, light weight, thin thickness, and good bendability, the flexible circuit board can significantly save space by folding and layering. [0003] After retrieval, the Chinese Patent Literature Announcement No. CN210381463U, dated April 21, 2020, discloses a multifunctional foldable flexible circuit board. The first part of the circuit board, the second part of the circuit board, the third part of the circuit board and the fourth part of the circuit board...
