[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0025] The utility model embodiment provides a wire material, such as Figure 1As shown, the wire material includes a coating layer 1, a core 2 and a first filler 3 for enhancing structural strength; the core 2 is coated in the coating layer 1. The core 2 includes a first core wire 21 and a second core wire 22, both of which are coated with a conductor 26, and the first filler 3 is filled in the first core wire 21 and the second core wire 22.

[0026] The wire of the utility model is filled with a first filler 3 in the first core wire 21 and the second core wire 22. The first filler 3 can be used to enhance the structural strength, thereby enhancing the structural strength of the first core wire 21 and the second core wire 22, and further enhancing the overall structural strength of the wire, thereby increasing the service life of the wire.

[0027] The first filler 3 can enhance the structural strength of the wire, which means that the wire can better resist the influence of external forces, such as stretching and compression, thereby reducing the stress and fatigue of the internal conductor 26 and extending the service life of the wire. The filling of the first filler 3 can also increase the bending life of the wire, because the first filler 3 can absorb and disperse the force generated during bending and folding.

[0028] Specifically, the first filler 3 is any one or a combination of nylon thread, nylon rope, fiber thread, cotton thread, and bulletproof thread. As fillers, nylon thread, nylon rope, fiber thread, cotton thread, and bulletproof thread all have good elasticity and toughness, improve the structural strength of the wire, allow the wire to maintain its shape and integrity when subjected to tensile or compressive forces, absorb and disperse the stress in the wire, protect the conductor 26 inside the wire from damage, and the wire is frequently bent and folded, and it is not easy to cause the internal conductor 26 to break or fatigue.

[0029] Specifically, when the first filler 3 is nylon thread or nylon rope, nylon thread or nylon rope is a synthetic fiber with high strength and wear resistance, and also has good elasticity and flexibility. As fillers, they can provide good tensile strength and protect the conductor 26 inside the wire from being stretched or bent. Fiber filaments refer to filaments made of a variety of natural or synthetic materials, such as cotton, linen, polyester, etc. When the first filler 3 is fiber filaments, the fiber filaments have good hygroscopicity and air permeability, can absorb and remove moisture inside the wire, and protect the conductor 26 from corrosion. Cotton thread is made of cotton fiber, has good hygroscopicity and ventilation, can protect the conductor 26 inside the wire from being affected by moisture. When the first filler 3 is cotton thread, cotton thread has good tensile resistance and can improve the structural strength of the wire. Bulletproof wire is made of high-performance materials such as ultra-high molecular weight polyethylene (UHMWPE) or aramid, and has extremely high strength and wear resistance. Using the bulletproof wire as the first filler 3 can provide extremely high tensile strength and have a certain degree of flexibility, thereby increasing the bending resistance life of the wire.

[0030] Specifically, the material of the conductor 26 can be selected from materials with good electrical conductivity, such as copper or aluminum. In addition, the conductor 26 can be arranged by twisting, weaving or other methods to improve the flexibility and bending life of the data line. The material of the conductor 26 can be any of copper wire, tinned copper, copper clad steel, and aluminum-magnesium wire. As one of the materials of the conductor 26, copper wire has excellent electrical conductivity and good thermal stability. Tinned copper is a layer of tin plated on the surface of the copper wire to prevent the copper wire from oxidizing, which can improve the corrosion resistance and weldability of the wire, and will not significantly reduce the conductivity, and can be used in application scenarios that require long-term stability. Copper clad steel wire is a composite wire composed of a steel wire coated with a layer of copper, which combines the good conductivity of copper and the high strength of steel, and can be used in applications that require high strength and good conductivity. Aluminum-magnesium wire is a wire made of aluminum and magnesium alloy, which has good conductivity and is lighter than copper wire, and can be used in weight-reducing applications.

[0031] The first core wire 21 is a VBUS core wire. The VBUS core wire is the power line in the USB data cable, which is responsible for providing the power supply voltage. In the USB specification, VBUS is the line that provides power between the USB device and the host, usually +5V DC. In the USB Type-C specification, the VBUS line can support higher voltage and current to achieve faster charging speed and higher power output. In the utility model, there are two VBUS core wires, and the two VBUS core wires are centrally symmetrical and spaced. In the existing high-current wire, the two VBUS core wires are closely arranged, which makes the wire hardness large and the softness poor. In this scheme, the two VBUS core wires are centrally symmetrical and spaced, and the VBUS core wires are separated, thereby improving the softness of the wire and improving the bending resistance life of the wire. In addition, the two VBUS core wires are centrally symmetrical and spaced, which can enhance the structural stability of the cable. This structural design can better balance the mechanical stress of the cable during use, avoid deformation of the cable due to eccentric load, and the two core wires are spaced, which can also reduce electromagnetic interference between each other, which is conducive to ensuring the stability and accuracy of data transmission. The spacing between the two VBUS core wires can improve the heat dissipation performance of the cable. This is very important for cables with high current transmission, because high current transmission will generate a lot of heat. If the heat cannot be dissipated in time, it may affect the performance of the cable and even cause the cable to overheat and be damaged.

[0032] The second core wire 22 is a signal wire, which can transmit data packet signals, protocol communication signals, etc. Further, the wire core 2 also includes a third core wire 23, which is coated with a conductor 26, and the first filler 3 is filled in the third core wire 23. The presence of the first filler 3 can increase the softness of the third core wire 23, thereby making the wire easier to bend and shape, and can also improve the bending resistance life of the cable. At the same time, the first filler 3 in the third core wire 23 can increase the overall stability of the core 2, prevent the conductor 26 from moving or deforming when subjected to external force, thereby protecting the conductor 26 and extending the service life of the cable. The third core wire 23 is a CC (Charging Circuit) core wire used to transmit charging-related signals and power. These lines are usually used to connect mobile devices (such as mobile phones, tablets) and charging devices (such as chargers, computer USB ports) to realize the charging function and data transmission of the device. CC core wires play an important role in USB charging and data transmission. Different USB standards (such as USB 2.0, USB 3.0, USB-C) may have CC lines with different configurations and uses. Although both CC and VBUS core lines involve power transmission, CC lines are more focused on charging negotiation and data transmission, while VBUS lines focus on providing direct power. In summary, CC lines are used for charging negotiation and data transmission, while VBUS lines are used to directly provide power to devices.

[0033] The wire core 2 includes a fourth core wire 24, and the fourth core wire 24 includes a conductor 26 formed by twisting, and the first filler 3 is filled in the conductor 26. The presence of the first filler 3 can increase the structural strength of the fourth core wire 24. Taking the conductor 26 as a copper wire as an example, multiple copper wires are twisted together to form the conductor 26 through a copper twisting process, and the first filler 3 is added during the twisting process to be twisted together, so that the first filler 3 is filled in the multiple conductors 26.

[0034] Specifically, the fourth core wire 24 is a ground wire, and the ground wire is a conductor 26 without an insulating layer 25. The current ground wire is generally coated with a plastic layer, which results in a large hardness and poor flexibility of the ground wire, thereby affecting the overall flexibility of the wire. Since the ground wire itself only needs to be grounded, the ground wire in this solution removes the plastic layer, which will not cause safety problems while reducing its hardness and improving its flexibility, thereby improving the overall flexibility of the wire. The first core wire 21, the second core wire 22, and the third core wire 23 can be wrapped with an insulating layer 25 such as PP, FEP, PE, and TPEE. Taking the conductor 26 as copper wire as an example, the conductor 26 of the first core wire 21, the second core wire 22, and the third core wire 23 can also be formed by twisting multiple copper wires into one body through a copper twisting process, and the first filler 3 is added during the twisting process to be twisted together, so that the first filler 3 is filled therein.

[0035] Furthermore, the first filler 3 is also directly filled in the internal space 15 of the coating layer 1. The internal space 15 of the coating layer 1 is the space for coating the first core wire 21, the second core wire 22, the third core wire 23 and the fourth core wire 24. That is, in this scheme, in addition to the first core wire 21, the second core wire 22, the third core wire 23 and the fourth core wire 24 being filled with the first filler 3, the coating layer 1 is also filled with the first filler 3, which can further improve the structural strength of the wire. The first filler 3 can also reduce the internal stress of the cable when it is bent and extend the bending life of the cable. The filler filled in the coating layer 1 can fill the gap in the coating layer 1, enhance the fixation of the first core wire 21, the second core wire 22, the third core wire 23 and the fourth core wire 24, enhance the structural stability of the cable, and prevent the cable from being deformed during use, thereby improving the reliability and durability of the cable.

[0036] On the other hand, the coating 1 includes a first shielding layer 11 and a second shielding layer 12, the core 2 is coated in the first shielding layer 11; the second shielding layer 12 coats the first shielding layer 11, and the first filler 3 is filled in the second shielding layer 12, which can further improve the structural strength of the wire. The first filler 3 is filled in the second shielding layer 12, and can also provide additional physical protection to prevent the cable from being damaged under stretching, bending or other physical stresses. The first shielding layer 11 coating the core 2 can effectively isolate the core 2 from electromagnetic interference from the external environment. The second shielding layer 12 further coats the first shielding layer 11, providing additional anti-interference protection. This double shielding design can provide a higher level of anti-interference performance. Specifically, the first filler 3 is filled on the outside and inside of the second shielding layer 12, which can greatly improve the structural strength.

[0037] Specifically, the first shielding layer 11 is any one or a combination of aluminum foil, graphene aluminum foil, and conductive cloth. Aluminum foil, as a shielding material, can prevent electromagnetic interference and has the advantages of low cost, light weight, good conductivity and reflectivity. Graphene aluminum foil is a special shielding material that combines graphite and aluminum foil, which can provide a higher level of anti-interference performance while also improving the strength and durability of the shielding layer. Conductive cloth is a cloth made of conductive material (such as copper or silver), which has high strength and good flexibility, is suitable for wires of various shapes and sizes, and has good conductivity and anti-interference performance.

[0038] The second shielding layer 12 is any one or a combination of copper wire and aluminum-magnesium wire. As a shielding material, copper wire has excellent electrical conductivity and can effectively reduce electromagnetic interference. Copper wire can appear in a woven form. This structure provides good durability and flexibility and can adapt to various complex wire shapes. Aluminum-magnesium wire is a wire made of aluminum and magnesium alloy, combining the advantages of both. Aluminum-magnesium wire is stronger than pure aluminum wire and lighter than copper wire. It has good electrical conductivity and can effectively reduce electromagnetic interference.

[0039] Specifically, the coating 1 also includes an outer coating 13 and a decorative braided layer 14; the outer coating 13 covers the second shielding layer 12, and the decorative braided layer 14 covers the outer coating 13. The outer coating 13 is coated on the second shielding layer 12, which can provide protection to prevent the internal shielding layer and core wire from being physically damaged and corroded by environmental factors such as moisture, chemicals, etc., and provide good insulation performance and wear resistance. The decorative braided layer 14 is coated on the outer coating 13, in addition to providing additional physical protection, increasing the wear resistance and tensile strength of the cable, it can also provide an aesthetic appearance to make the cable more attractive. The outer coating 13 can be any one of PVC, TPE, and TPU, and the decorative braided layer 14 can be any one of nylon yarn, fiber yarn, and low-elastic yarn or a combination thereof.

The data cable can be used for data transmission or charging of electronic devices such as mobile phones.

For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present utility model.
