[0002] With the development of wireless charging technology, foldable wireless charging devices with multiple charging positions are becoming more and more popular. Since the charging cables connecting various wireless charging devices are often bent and twisted multiple times due to usage or storage needs, the charging cables are easily broken when FPC soft cables are used, and the charging cables often have defects such as twisting and bulging when large-diameter wire cores are used. Twisting and bulging not only affect the appearance of the charging cable, but also are accompanied by the twisting and deformation of the wire core. If used for a long time, there is a risk of burning the wire. Therefore, the charging cable can use a small-diameter wire core to solve the above problems. However, the small-diameter wire core has the problems of not being resistant to pulling and not being able to withstand pulling and not having enough power. Therefore, wireless charging devices with multiple charging positions are in urgent need of providing a charging cable structure that can prevent bulging while being resistant to pulling and having sufficient power.
