Problems solved by technology

After the flexible circuit board is installed, due to the lack of necessary dust-proof measures, the flexible circuit board is easy to absorb dust in the air and causes dust to form on the surface of the flexible circuit board, which will affect the normal use of the flexible circuit board, and The heat generated by the flexible circuit board during use will heat the surrounding air, and the existing flexible circuit board can only dissipate heat through the cooling holes, the heat dissipation effect is not good, and it is easy for dust to adhere to the flexible circuit On the board, and in the case of excessive heat, it will affect the working efficiency of the flexible circuit board, which will seriously cause the flexible circuit board to be burned, and, due to the lack of protective measures, the flexible circuit board will be damaged by external factors

Abstract

The invention discloses a flexible circuit board with an external dustproof mechanism, which comprises a flexible circuit board body. The dustproof mechanism is arranged outside the flexible circuit board body, and the dustproof mechanism comprises an upper dustproof frame, a first dustproof net, a lower dustproof frame, a second dustproof net, a convex block and a fixed block. Connecting mechanisms are respectively arranged on the front side wall and the rear side wall of the upper dustproof frame. The invention discloses a flexible circuit board with external dustproof mechanism, which belongs to the field of flexible circuit boards, the flexible circuit board body is clamped between an upper dustproof frame and a lower dustproof frame through the mutual cooperative use of the dustproof mechanisms, and dust is blocked through a first dustproof net and a second dustproof net, dust is prevented from being attached and accumulated on the upper surface and the lower surface of the flexible circuit board body, the protection mechanism is arranged to protect the flexible circuit board body between the upper protective shell and the lower protective shell, and the problem that the flexible circuit board body is damaged due to external factors is avoided.

Description

technical field [0001] The invention relates to the field of flexible circuit boards, in particular to a flexible circuit board with an external dust-proof mechanism. Background technique [0002] Flexible circuit boards, also known as "soft boards", are printed circuits made of flexible insulating substrates. Flexible circuits provide excellent electrical performance, can meet the design needs of smaller and higher density mounting, and also help reduce assembly processes and enhance reliability. Flexible circuit boards are the only solution to meet the miniaturization and mobility requirements of electronic products. It can be bent, wound, and folded freely, and can withstand millions of dynamic bendings without damaging the wires. It can be arranged arbitrarily according to the spatial layout requirements, and can be moved and stretched in three-dimensional space, so as to achieve the integration of component assembly and wire connection. The flexible circuit board can ...
