[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] This utility model embodiment provides a data cable, such as Figure 1 and Figure 2As shown, the device includes a core material 1 and a protective layer 2, with the protective layer 2 enclosing the core material 1. The core material 1 includes a first tensile filament 11 and several composite filaments 12. The composite filaments 12 extend along the axial direction of the first tensile filament 11 and are spirally wound around the first tensile filament 11, so that the first tensile filament 11 is located in the surrounding space 13 of the composite filaments 12. The composite filaments 12 include a second tensile filament located at the center and a metal wire spirally wound around the second tensile filament.

[0023] The core material 1 of this utility model data cable is provided with several composite wires 12, wherein the composite wires 12 extend and are laid along the axial direction of the first tensile wire 11 and are spirally wound around the first tensile wire 11, so that the first tensile wire 11 is located in the surrounding space 13 of the composite wires 12, and the data cable is formed after wrapping the protective layer 2. The first tensile wire 11 has the characteristics of being resistant to swinging, tensile strength, and high flexibility. On this basis, the composite wires 12 are spirally wound around the first tensile wire 11, and the second tensile wire and the metal wire spirally wound outside the second tensile wire are also resistant to swinging, tensile strength, and high flexibility, so that the overall swing resistance, tensile strength, and high flexibility of the data cable are better, and the data cable is not easily damaged under long-term use.

[0024] Specifically, the composite wire 12 includes a second tensile wire at the center and a metal conductor wire spirally coiled around the second tensile wire. The metal conductor wire is a copper foil wire 121, which has resistance to swaying, tensile strength, and high flexibility. The second tensile wire also has resistance to swaying, tensile strength, and high flexibility. The composite wire 12 is formed by combining the copper foil wire 121 and the second tensile wire. The composite wire 12 is spirally wound around the first tensile wire 11 in the axial direction. Both are spirally wound around the first tensile wire 11 in a cross spiral shape. The first tensile wire 11 also has resistance to swaying, tensile strength, and high flexibility, which makes the overall data cable more resistant to swaying, tensile strength, and high flexibility, and the data cable is not easily damaged even after long-term use.

[0025] Specifically, the tensile filament is a fiber or filamentous material with high tensile strength. The first tensile filament 11 and the second tensile filament can be nylon filament, bulletproof filament, hemp fiber, or other tensile materials 1212, etc. The copper foil filament 121 also has conductivity and is used for conduction or signal transmission in the data cable of this utility model. As one example, such as Figure 3 As shown, copper foil wire 121 can be formed by winding copper wire 1211 around a tensile material 1212. The tensile material 1212 can be bulletproof wire, nylon wire, hemp fiber, or other tensile materials. Copper foil wire 121 has good elasticity, flexibility, and bending strength, and its middle part bears longitudinal tensile force, therefore its swaying and bending performance is much higher than that of ordinary conductors. Copper foil wire 121 can be bare copper foil wire, tin-plated copper foil wire, tin-plated alloy copper foil wire, silver-plated copper foil wire, silver-plated alloy copper foil wire, copper-clad aluminum foil wire, etc.

[0026] The core material 1 also includes a flattening layer 14, which is located between the composite wire 12 and the protective layer 2. The flattening layer 14 is wrapped around the composite wire 12, and the protective layer 2 covers the flattening layer 14. The composite wire 12 is spirally wound around the first tensile wire 11, which may result in some gaps or unevenness. The flattening layer 14, located between the composite wire 12 and the protective layer 2, can fill these gaps or unevenness, making the surface of the composite wire 12 smoother. In this way, when wrapping the protective layer 2, the protective layer 2 can adhere more evenly and tightly to the core material 1, avoiding problems such as uneven thickness and wrinkling of the protective layer 2 caused by surface unevenness, thus improving the overall appearance quality and manufacturing process of the data cable.

[0027] Furthermore, the leveling layer 14 consists of multiple copper wires extending along the axial direction of the first tensile wire 11 and spirally wound around the composite wire 12. The multiple copper wires wound around the composite wire 12 level any unevenness in the core material 1. Simultaneously, the spiral wound copper wires around the composite wire 12 share the tensile force with the first tensile wire 11, significantly improving the overall tensile strength of the data cable. This structure makes the data cable less prone to breakage during use, especially under frequent plugging and unplugging, dragging, and other operations, maintaining a good connection. Copper wires have good conductivity; the multiple copper wires spirally wound around the composite wire 12 also serve as conductors in the data cable for conducting electricity or signal transmission.

[0028] Furthermore, the protective layer 2 includes an inner insulation layer 21, which wraps around the composite wire 12 and the first tensile wire 11. The inner insulation layer 21 directly wraps around the composite wire 12 and the first tensile wire 11, providing additional insulation protection for the conductive copper foil wire 121 and the copper wire, effectively preventing the internal copper wire from becoming loose. This effectively prevents the copper foil wire 121 and the copper wire from coming into contact with the external environment or other conductive substances during use due to wear, aging, etc., leading to safety accidents such as short circuits or leakage, thus improving the safety and insulation performance of the data cable. The inner insulation layer 21 also provides a certain degree of electromagnetic shielding, reducing interference from external electromagnetic signals to the signals transmitted inside the data cable, and also preventing electromagnetic radiation from the signals inside the data cable to the external environment, ensuring the stability and accuracy of data transmission, which is particularly important for high-speed data transmission and the connection of precision electronic equipment.

[0029] Specifically, there are multiple core materials 1, each covered with an inner insulation layer 21. The protective layer 2 includes an outer insulation layer 22, which wraps around the inner insulation layer 21 to enclose the multiple core materials 1. The inner insulation layer 21 on each core material 1 provides the first layer of insulation protection, preventing short circuits and leakage between the core materials 1. The outer insulation layer 22 provides the second layer of insulation protection, further enhancing the overall insulation performance. This multi-layered insulation design can effectively prevent electromagnetic interference from the external environment, ensuring the stability and reliability of data transmission.

[0030] The protective layer 2 includes an outer braided layer 23, which wraps around the outer insulation layer 22. The outer braided layer 23 can be made of abrasion-resistant materials such as nylon or polyester fiber, effectively reducing friction between the data cable and the external environment during use, preventing wear on the outer insulation layer 22, and thus extending the data cable's lifespan. The outer braided layer 23 increases cable depth and tensile strength, reduces the overall elongation of the outer insulation layer 22 and prevents surface damage, and further enhances the data cable's insulation performance, preventing external conductive substances from contacting the outer insulation layer 22 and causing short circuits or leakage, thus improving the data cable's safety. The outer braided layer 23 can be made of polyester, nylon, Kevlar fiber, or other polyester fibers.

[0031] Specifically, there are five core materials 1; the five core materials 1 are arranged side by side in sequence, or three of the core materials 1 are arranged side by side, and the remaining two core materials 1 are arranged side by side on one side of the three core materials 1 arranged side by side.

[0032] This utility model also discloses a power bank, including the aforementioned data cable. The data cable serves as the power bank's charging cable and is plugged into the charging port of an electronic device for charging.
