Description

TECHNICAL FIELD

[0001] The utility model relates to the field of flexible circuit board, especially relates to a spliced flexible circuit board. BACKGROUND

[0002] Flexible circuit board is also called "soft board", which is a printed circuit made of flexible insulating substrate. Flexible circuit provides excellent electrical performance, can meet the design needs of smaller and higher density installation, and also helps to reduce assembly process and enhance reliability. Flexible circuit board is the only solution to meet the requirements of miniaturization and mobility of electronic products. It can be freely bent, wound and folded, can withstand millions of dynamic bending without damaging the wire, can be arranged arbitrarily according to the space layout requirements, and can be moved and stretched arbitrarily in three-dimensional space, so as to achieve the integration of component assembly and wire connection; flexible circuit board can greatly reduce the volume and weight of electronic products, and meet the needs of the development of electronic products towards high density, miniaturization and high reliability.

[0003] In the prior art, although the flexible circuit board can be bent and folded, its length and area are still limited. By splicing, multiple flexible circuit boards can be combined together, so as to expand the length or area of the whole circuit board to meet the needs of specific applications. At present, flexible circuit boards mostly use elastic clamping or screw fixing to realize the splicing between multiple flexible circuit boards. However, after splicing by elastic clamping, the flexible circuit boards are prone to loose and separate when subjected to external pulling force, which reduces the firmness and stability of the spliced flexible circuit boards. When splicing by screw fixing, it is relatively troublesome to operate, which brings inconvenience to the splicing of flexible circuit boards. UTILITY MODEL CONTENTS
