Abstract

The invention discloses a flat cable with a retractor for preventing stacking and bending. Active connection, the take-up center shaft includes side brackets, main brackets, correction limit bars, and rotating cores. When the flat cables are reeled, the cables can be rotated and reeled along the surface of the main bracket.
