Description

Technical Field

[0001] The utility model relates to the technical field of circuit board wiring, in particular to a bending-resistant structure for circuit board wiring. Background Art

[0002] FFC cable is a flexible flat cable, which is widely used in peripheral communication connections of electronic devices such as computers, scanners, printers, copiers, digital cameras, LCD monitors, etc. It is especially suitable for use as data transmission cables between mobile parts and motherboards, between PCB boards, and in miniaturized electrical equipment.

[0003] Most of the existing cables are composed of several flexible conductors arranged side by side, which makes the FFC cable soft and easy to bend and fold. Therefore, when the cable is folded and fixed, it is easy to form a fold in half. The folding of the cable in half can easily cause the line to break, affecting normal use. Therefore, in order to correct the above defects, we propose a bending-resistant structure for circuit board cables. Utility Model Content
