[0002] Magnetic charging cables are charging cables with magnetic attraction function, usually used for charging devices, such as smartphones, tablets, Bluetooth headsets, etc. Their main feature is that the end of the charging plug is attached with magnets, which can be adsorbed on the charging port of the device, thus simplifying the plug-in and unplugging operations and improving the convenience of use.

[0003] Publication number CN208782175U discloses a magnetic charging cable, including a power input end, a power output end and a connecting line. The power input end is a USB interface, and the USB interface includes a male interface and a packaging rubber seat. The wiring part of the male interface is composed of a wiring circuit board, one end of the wiring circuit board is electrically connected to the power line and the ground line, and the other end of the wiring circuit board is electrically connected to the insertion part. A chip self-resetting fuse and a resistor are provided on the wiring circuit board, so that the charging cable of the utility model has a power-off protection function. The power output end includes a male end shell and a male end magnetic suction connector arranged in the male end shell. The male end magnetic suction connector is composed of a hollow annular magnet, a plastic column and a spring ejector pin, so that the spring ejector pin is connected and conducted with the corresponding female pin pin. The magnetic suction area of ​​the annular magnet is large, and power can be directly supplied after connection. The operation is convenient and the connection can be achieved without any plugging and unplugging action. In addition, the structure is simple, the assembly is convenient, and the docking is stable. However, this type of magnetic charging cable is not equipped with a winding mechanism. When the charging cable is not in use, the charging cable is always exposed, which will accelerate the aging of the surface and thus shorten the service life of the charging cable. In addition, the charging cable is prone to getting tangled or folded during carrying, which will also shorten the service life of the charging cable and reduce its durability, which needs to be improved.

[0034] Embodiment 2

[0035] See also Figure 1-5 A mounting frame 16 is fixedly installed on the surface of the storage shell 4, and a T-shaped slot 17 is opened on the inner side of the mounting frame 16. A T-shaped plate 18 is inserted on the inner side of the T-shaped slot 17, and a frame plate 19 is fixedly installed on the side of the T-shaped plate 18. The frame plate 19 is ∩-shaped, and bristles 20 are arranged on the inner side of the frame plate 19. During the process of winding the wire body 1, it will pass through the mounting frame 16.

Then, after the wire body 1 is wound up, the block 9 will pop out under the action of the spring 10 and reset inside the adjacent groove 11. At this time, the storage and fixation of the wire body 1 is completed. , and thus can provide effective protection. During the winding process of the wire body 1, it will pass through the mounting frame 16, and under the action of the bristles 20, the impurities and dust on the surface of the wire body 1 will be brushed off, thereby preventing the dust and impurities on the surface of the wire body 1 from being brought into the storage shell 4, and the cleaning effect of the wire body 1 can be improved. When it is necessary to clean and maintain the bristles 20, first rotate the limiting piece 21 so that it no longer presses against the T-shaped plate 18, and then pull out the frame plate 19 and the T-shaped plate 18 along the T-shaped slot 17, so that the bristles 20 can be maintained. During installation, first align the T-shaped plate 18 with the T-shaped slot 17 and insert it downward, and then rotate the limiting piece 21 so that it presses against the top of the T-shaped plate 18, so that the installation of the frame plate 19 can be completed.
