Abstract
The invention relates to a flexible cable for controlling electronic signals. The flexible cable comprises three strands of insulating cable cores, wherein the three strands of insulating cable cores are mutually stranded. In each insulating cable core, a polyester film layer is arranged in the innermost layer of the insulating cable core, a total braided shielding layer coats the polyester film layer, and an insulating sheath layer further coats the total braided shielding layer. The cable for controlling electronic signals is made of flexible stranded copper wires and flexible polyether type TPU resin, so that the cable for controlling electronic signals can adapt to mobile occasions. By the adoption of the polyethylene insulating layers, low dielectric loss is beneficially achieved; by the adoption of the total braided shielding layers, the effect of highly resisting electromagnetic interference is achieved; by the adoption of the polyether type TPU resin, the flexible cable for controlling electronic signals can have the advantages of being good in flexibility and flexing resistance, low in smoke, free of halogen flame retardant, good in insulating stability, and capable of resisting acid, alkali, hydrolysis and aging.
