Composite flexible circuit board for capacitive touch screen

Abstract

The invention relates to the technical field of composite flexible circuit boards, in particular to a composite flexible circuit board for a capacitive touch screen, which comprises a circuit board body. A fixing structure is arranged on the circuit board body; a connecting structure is arranged on the inner side of the fixing structure; a furling structure penetrates through the circuit board body; a retaining structure is arranged on the inner side of the furling structure; and the side surface of the circuit board body is provided with a layered structure. The connecting position of the circuit board body and the port is protected through the fixing structure, the interface is prevented from being damaged by pulling, the circuit board body is conveniently disassembled and assembled through the connecting structure, the circuit board body with the redundant length is wound through the winding structure, and the internal space of the device shell is saved. The condition that the rolled circuit board body rotates is avoided through the retaining structure, and a gap between the circuit board bodies which are arranged on the two sides in an overlapped mode is supported through the layered structure, so that attachment is avoided.

Description

technical field [0001] The invention relates to the technical field of composite flexible circuit boards, in particular to a composite flexible circuit board for a capacitive touch screen. 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 flexi...

Problems solved by technology

[0003] However, traditional flexible circuit boards only rely on the packaging film on the surface to protect the internal circuits, so that if the flexible circuit board part is repeatedly bent or pulled during machine repair and maintenance, it is easy to make the flexible circuit board Breakage or even damage to the connection port. At the same time, if multi-layer flexible circuit boards are used for stacking, it is not convenient for the heat dissipation of the circuit board. At the same time, it may increase the corrosion of the circuit board and affect the service life.
