Fig. 1 is a schematic structural diagram of a data line 100 according to an embodiment of the present invention.
As shown in fig. 1, the data line 100 of the present embodiment includes a data line insulating layer 10, a data line shielding layer 20, a power line 30, a signal line 40, an electronic line 50, a ground line 60, a fiber line 70, and a fiber line 80.
The data line insulating layer 10 is located at the outermost layer, which is located outside the data line shielding layer 20 and covers the data line shielding layer 20. The data line insulating layer 10 serves to insulate various core lines within the data line 100, such as the power line 30, the signal line 40, the electronic line 50, the ground line 60, and the like, from the outside, thereby preventing leakage and interference. The data line insulating layer 10 may be made of an organic insulating material, such as plastic, and coated with an insulating varnish on the outer surface.

The power line 30 is used for transmitting electric energy, and in this embodiment, a single power line in the original data line is split into more than 2 power lines, for example, 2, 3, or 4 power lines. Exemplarily, in the present embodiment, the data line 100 includes 3 power lines 30. Because the power lines are split into more than 2, the resistance of the core wires of the power lines can be improved equally when the length is the same, so that the related electrical performance requirements can be met even if the data lines with the length of more than 1m are manufactured, the wire diameter of each power line is smaller, and when all the core wires are twisted together, the core wires and the core wires can be tightly attached together, so that the overall wire diameter of the data lines is thinned, and the structure is more compact; and when the data line is bent and flexed in the use process, the stress in the data line can be released towards the same direction, so that the data line is very soft, and the use hand feeling of the data line is improved.

Further, a plurality of core wires in the core wire group can be directly twisted together, or can be divided into a plurality of groups of core wires, then each group of core wires are respectively twisted, namely, the core wires in each group of core wires are twisted with each other, then each group of core wires are twisted with each other, and of course, each group of core wires can be untwisted. In the present embodiment, since the core wire set includes a plurality of strands of core wires 32, the wire diameter of each strand of core wire 32 becomes smaller, and when all the core wires are twisted together, the core wires and the core wires can be closely attached together, which makes the power wire 30 and the data wire 100 become more flexible.
Further, in this embodiment, a fiber wire may be added to each core wire set of the power line 30, and the fiber wire is filled to further enhance the mechanical performance of the power line 30, and further enhance the mechanical performance of the data line, so that the data line becomes softer and more resistant to folding. Illustratively, the material of the fiber thread includes aramid fiber, nylon yarn, or high-strength polyethylene fiber.
It should be understood that the number of fiber strands filled in the core assembly is premised on not affecting the electrical properties of the core.

Wherein the fiber line 70 is arranged at an edge position of the cavity and the fiber line 80 is arranged at the center of the cavity, i.e., surrounded by the power line 30, the signal line 40, the electronic line 50 and the ground line 60. The fiber thread 80 has a larger thread diameter and the fiber thread 70 has a smaller thread diameter. Illustratively, the material of the fiber thread includes aramid fiber, nylon yarn, or high-strength polyethylene fiber.
In this embodiment, since the fiber wire added to the data wire 100 has the characteristics of high strength and low elongation, it is possible to bear a strong tensile force during the stress process of the metal conductor to protect the metal conductor, and thus the reliability and the service life of the data wire 100 can be increased by such a structure. Meanwhile, the space occupied by the non-metal material in the core conductor is very limited, so that the conductive effect of the core conductor cannot be influenced.
Further, in this embodiment, the power line is split into a plurality of core wires with smaller wire diameter, and the fiber filler is added in the gap between the core wires, so that a tightly arranged structure is formed between the core wires, and the stress point of the data line 100 is not concentrated at a certain point when the data line is bent and flexed, so that the data line 100 is not easily broken, and the reliability and durability of the data line are further increased.

According to the data line and the charger, a new power line core wire structure is adopted, and the power lines are disassembled into 2 or more than 2, so that the resistance of the power line core wires can be equally improved when the length is the same, the wire diameter of each power line core wire is reduced, when all the core wires are twisted together, the core wires and the core wires can be tightly attached together, the overall wire diameter of the data line is reduced, and the structure is more compact; when the data line is bent and flexed in the use process, the stress in the data line can be released towards the same direction, so that the data line is very soft; meanwhile, due to the close arrangement structure of the core wires, stress points of the data wire cannot be concentrated at a certain point when the data wire is bent and flexed, so that the data wire cannot be broken easily. In addition, because the added fillers such as Kevlar fibers and the like have the characteristics of high strength and low elongation, the added fillers can bear strong tensile force in the stress process of the metal conductor to protect the metal conductor, and therefore the structure can simultaneously increase the reliability and prolong the service life of the data line. Meanwhile, the space occupied by the non-metal material in the core conductor is very limited, so that the conductive effect of the core conductor cannot be influenced.
