AI Technical Summary
Technical Problem
Existing flexible flat cables are difficult to bend flexibly in a limited space, leading to localized stress concentration, which affects signal transmission quality and device stability.
Method used
The flexible flat cable is divided into multiple pin-separated flat cables with gaps between adjacent cables. These cables are then secured with adhesive tape to create overlapping areas, increasing flexibility. Conductive cloth is used for shielding.
Benefits of technology
This allows the flexible flat cable to be easily bent without changing its cross-sectional width, avoiding localized stress and ensuring signal transmission quality and connection stability.

Abstract
This disclosure provides a bendable flexible flat cable structure and an electronic device. The structure includes a first fixing tape, a bendable flexible flat cable body, and two conductive cloths. The bendable flexible flat cable body includes a first connecting portion, an intermediate transition portion, and a second connecting portion. The intermediate transition portion has multiple branch pins, with a reserved gap between two adjacent branch pins to insulate the multiple branch pins from each other. Partial areas of the multiple branch pins overlap to form an overlapping area. The first fixing tape is wrapped around and bonded to the overlapping area. In this way, although the cross-sectional width of the bendable flexible flat cable body is not changed, the cross-sectional width of the branch pins is smaller after branching. Therefore, compared with the flexible flat cable before branching, the bendable flexible flat cable body of this solution is easier to bend and will not generate local stress. It can be properly wired when connecting two PCB boards, ensuring signal transmission quality.
