[0020] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] Please see Figures 1 to 2The first aspect of this application provides a data cable 100, which includes a terminal assembly 1, a core wire assembly 2, a braided layer 3, and a filling layer 4.

[0023] Terminal assembly 1 is used to connect electronic devices, such as mobile phones, tablets, laptops, desktop computers, chargers, etc. The type of terminal assembly 1 can be, for example, USB-A, USB-C, etc.

[0024] The core wire assembly 2 is connected to the terminal assembly 1. The core wire assembly 2 is used for conducting electricity, which can be used to charge the electronic device, transmit data to the electronic device, or transmit data while charging. Typically, terminal assemblies 1 are provided at both ends of the core wire assembly 2, and the two terminal assemblies can be of the same or different types.

[0025] A braided layer 3 covers the outer surface of the core wire assembly 2. The braided layer 3 can be made of materials such as nylon. When the user pulls the data cable 100, the braided layer 3 can withstand part of the tensile force, thereby protecting the core wire assembly 2. The braided layer 3 not only enhances the durability of the data cable 100 but also improves its appearance. The braided layer 3 can be a mesh structure woven from nylon filaments, thereby improving the toughness and abrasion resistance of the data cable 100.

[0026] It is understandable that, since the braided layer 3 is made of silk, it has multiple braiding gaps 31, including gaps between individual strands of silk. It is also understandable that, since each individual strand of silk may be woven from multiple finer strands, and there are also gaps between these finer strands, the multiple braiding gaps 31 also include gaps within each individual strand of silk. The filling layer 4 fills the multiple braiding gaps 31, thus tightly bonding with the braided layer 3. Optionally, the filling layer 4 is made of a flexible and skin-friendly material, making the data cable 100 more flexible, providing a better feel, and exhibiting better bending resistance, making it less prone to damage during bending.

[0027] In the embodiments provided in this application, a filling layer 4 is provided in a plurality of braiding gaps 31. The filling layer 4 can completely or partially fill the braiding gaps 31, thereby making it difficult for dust and stains to accumulate in the braiding gaps 31. The filling layer 4 and the braiding layer 3 together cover the core wire assembly 2, which can prevent dust and stains from entering and adsorbing in the braiding layer 3, prevent the data cable 100 from accumulating dust, and thus improve the dirt resistance of the data cable 100.

[0028] Meanwhile, since the braided layer 3 is made of silk fabric, such as polyester, nylon, or cotton yarn, it is prone to pilling. In this embodiment, the filling layer 4 is tightly bonded to the braided layer 3, and the filling layer 4 also protects the braided layer 3 to minimize pilling. In addition, the filling layer 4 can also improve the tensile strength and waterproof performance of the data cable 100.

[0029] In some embodiments of this application, the filler layer 4 is made of one or more of methyl vinyl siloxane, silica, hydrogen-containing silicone oil, and light white oil. Optionally, the filler layer 4 is made of 25-35 parts by weight of methyl vinyl siloxane, 10-20 parts by weight of silica, 10-20 parts by weight of hydrogen-containing silicone oil, and 35-45 parts by weight of light white oil. For example, the filler layer 4 is made of 25 parts by weight of methyl vinyl siloxane, 20 parts by weight of silica, 20 parts by weight of hydrogen-containing silicone oil, and 35 parts by weight of light white oil. Alternatively, the filler layer 4 is made of 35 parts by weight of methyl vinyl siloxane, 10 parts by weight of silica, 10 parts by weight of hydrogen-containing silicone oil, and 45 parts by weight of light white oil. Alternatively, the filler layer 4 is made of 30 parts by weight of methyl vinyl siloxane, 15 parts by weight of silica, 15 parts by weight of hydrogen-containing silicone oil, and 40 parts by weight of light white oil.

[0030] Hydrogen-containing silicone oil is an organosilicon oil with good lubrication properties and excellent hydrophobicity, forming a waterproof layer to prevent moisture from entering the braided gaps 31 and avoiding interference with the core wire assembly 2. Methyl vinyl siloxane not only has good lubrication and waterproof properties but also adhesive properties, allowing the filler layer 4 to be firmly connected to the braided layer 3. Furthermore, methyl vinyl siloxane has excellent sealing properties, preventing gaps between the filler layer 4 and the braided layer 3 that could allow dust to enter, thus enhancing the anti-fouling performance of the data cable 100. Among these, methyl vinyl siloxane, hydrogen-containing silicone oil, and light white oil all have lubrication properties, which not only improve the dirt resistance of the data cable 100 but also prevent the data cable 100 from developing a rough surface, thereby preventing pilling.

[0031] In some embodiments, the filler layer 4 may further comprise 5-10 parts by weight of silicone varnish. For example, the filler layer 4 comprises 25 parts by weight of methyl vinyl siloxane, 20 parts by weight of silica, 15 parts by weight of hydrosilicone oil, and 35 parts by weight of light white oil, with 5 parts by weight of silicone varnish. Alternatively, the filler layer 4 comprises 30 parts by weight of methyl vinyl siloxane, 10 parts by weight of silica, 10 parts by weight of hydrosilicone oil, and 40 parts by weight of light white oil, with 10 parts by weight of silicone varnish. Alternatively, the filler layer 4 comprises 30 parts by weight of methyl vinyl siloxane, 11 parts by weight of silica, 14 parts by weight of hydrosilicone oil, and 37 parts by weight of light white oil, with 8 parts by weight of silicone varnish. Silicone varnish has a smooth feel and a matte finish, exhibiting excellent skin-friendly properties, further enhancing the usability of the data cable 100. Furthermore, silicone varnish also has anti-allergic effects, making it more user-friendly.

[0032] It should be noted that the dirt-resistant function of the data cable 100 is achieved by filling the braid gaps 31 of the braided layer 3 with a hydrophobic filler layer 4. Therefore, the material of the filler layer 4 includes, but is not limited to, the above-mentioned formulation. In some embodiments, the material of the filler layer 4 may also include other hydrophobic nano-coatings. By the coating penetrating into the gaps of the braided layer, the coating also achieves the dirt-resistant function after curing.

[0033] In some embodiments of this application, the core wire assembly 2 includes a core wire 23, a shielding layer 22, and an insulating layer 21.

[0034] The core wire 23 can be used to conduct electricity. The core wire 23 includes, by way of example, multiple fine wires. The number of fine wires may vary depending on the type of terminal assembly 1.

[0035] The shielding layer 22 covers the core wire 23, preventing external electromagnetic interference from affecting the signal transmitted by the core wire 23. Electromagnetic interference may originate from other electronic devices, power lines, or other wireless signal sources. This interference may interfere with the weak signal transmitted in the data line 100, leading to data transmission errors or performance degradation. By providing a conductive barrier, the shielding layer 22 effectively guides these interference signals to the ground wire, thereby protecting the signal transmitted by the internal core wire 23 from being affected. Furthermore, the shielding layer 22 also reduces signal radiation outward.

[0036] The shielding layer 22 can be made of graphene, which provides effective electromagnetic shielding over a wide frequency range, offering good shielding performance from low to high frequencies. Graphene can also be combined with other materials to create a flexible shielding layer 22, improving the flexibility of the data cable 100. Graphene can be fabricated into very thin single-layer or few-layer structures, helping to reduce the weight and volume of the core wire assembly 2 of the data cable 100 while maintaining electromagnetic shielding effectiveness. The shielding layer 22 can also be covered with multi-strand nylon threads 24, improving the overall toughness of the data cable 100.

[0037] The insulating layer 21 covers the shielding layer 22, and the insulating layer 21 provides insulation to prevent leakage of the core wire 23. The insulating layer 21, wrapped around the shielding layer 22, protects the data cable 100 from external environmental factors (such as moisture and dirt) and also secures the core wire 23. The insulating layer 21 also provides a degree of physical protection, preventing mechanical damage to the core wire 23 and the shielding layer 22. The insulating layer 21 is made of one or more of silicone, thermoplastic elastomer, Teflon, H&R, or modified polypropylene. Silicone, thermoplastic elastomer, Teflon, H&R, and modified polypropylene are all high-temperature resistant materials, enabling the data cable 100 to withstand high-temperature environments. It should be noted that since applying the filler layer 4 requires a baking process, the insulating layer 21 in this embodiment is made of a high-temperature resistant material, allowing it to withstand the high temperatures of the baking process during the application of the filler layer 4.

[0038] like Figure 3 As shown, in some embodiments of this application, the terminal assembly 1 includes a connecting terminal 11, an inner mold 13, and a housing 12.

[0039] The connecting terminal 11 is connected to the core wire assembly 2. The connecting terminal 11 has a plugging direction, which is the direction in which the connecting terminal 11 is plugged into the electronic device. The connecting terminal 11 can be a male or female connector.

[0040] The inner mold 13 covers the connection between the connecting terminal 11 and the core wire assembly 2. The inner mold 13 can be a plastic inner film, and it is formed at the connection between the connecting terminal 11 and the core wire assembly 2 by injection molding. This results in a lower cost for the inner mold 13, while providing good insulation and ensuring the insulation effect at the connection between the core wire assembly 2 and the connecting terminal 11, thereby minimizing safety hazards such as short circuits or electric shocks. Moreover, the inner mold 13 can seal the connection between the core wire assembly 2 and the connecting terminal 11, which on the one hand improves the strength of the connection between the connecting terminal 11 and the core wire assembly 2 and enhances the waterproof effect at the connection between the connecting terminal 11 and the core wire assembly 2, and on the other hand helps to reduce electromagnetic interference and radio frequency interference, improving the stability and accuracy of data transmission of the core wire assembly 2.

[0041] like Figure 4 As shown, the outer casing 12 has a receiving cavity 121, and the inner mold 13 is disposed within the receiving cavity 121. The outer casing 12 can protect the inner mold 13. The outer casing 12 is exemplarily made of aluminum alloy, which results in high strength, long service life, and good heat dissipation. The outer wall of the outer casing 12 has a first surface 125 and a second surface 122 disposed opposite to each other in the insertion direction. The first surface 125 has a first opening 1251 through which the connecting terminal 11 passes, i.e., the first opening 1251 communicates with the receiving cavity 121, and the connecting terminal 11 can pass through the first opening 1251 to connect with the electronic device. The second surface 122 has a second opening 1221 through which the core wire assembly 2 passes, i.e., the second opening 1221 communicates with the receiving cavity 121, and the core wire assembly 2 can pass through the second opening 1221 to connect with the connecting terminal 11 at the other end. The surface of the second opening 1221 facing the core wire assembly 2 is a third surface 123, and the cross-section at the junction of the third surface 123 and the second surface 122 is curved. Compared to the conventional sharp edges at the junction of the third surface 123 and the second surface 122, the sharp edges of the outer casing 12 may cut the data cable 100, causing damage. In this embodiment, the cross-section at the junction of the third surface 123 and the second surface 122 is curved. The curved surface has a larger contact area with the core wire assembly 2, resulting in less pressure from the outer casing 12 on the core wire assembly 2. This reduces localized wear on the core wire assembly 2 caused by the outer casing 12 and minimizes the risk of the data cable 100 being cut by the outer casing 12.

[0042] It should also be noted that, in order to solve the problem of easy damage at the connection between the core wire assembly 2 and the outer casing 12, a stress relief sleeve made of rigid material is usually fitted at the end of the core wire assembly 2.

[0043] The data cable 100 of this application is provided with a braided layer 3 and a filling layer 4. The braided layer 3 and the filling layer 4 can improve the strength of the core wire assembly 2, making the core wire assembly 2 less prone to damage. On the other hand, a curved surface is provided at the junction of the third surface 123 and the second surface 122, thereby reducing stress concentration. In this way, the data cable 100 does not need to be provided with a stress relief sleeve, and its service life can be guaranteed, thereby making the structure of the data cable simpler.

[0044] like Figure 4 and Figure 7As shown, in some embodiments, the cross-section at the junction of the third surface 123 and the second surface 122 is an arc surface, which facilitates processing. The arc surface also provides more clearance for the core wire assembly 2. When the core wire assembly 2 bends, the contact area between the core wire assembly 2 and the outer shell 12 is smaller, thereby minimizing damage to the core wire assembly 2 and extending the service life of the data cable 100. When the core wire assembly 2 bends, the arc surface can limit the bending amplitude of the core wire assembly 2, thereby making the bending amplitude of the core wire assembly 2 more uniform throughout, minimizing the risk of breakage. The radius corresponding to the arc surface is greater than or equal to 0.15 mm and less than or equal to 0.5 mm. For example, the radius corresponding to the arc surface can be 0.15 mm, 0.2 mm, or 0.3 mm. If the radius corresponding to the arc surface is too large, the bending amplitude of the core wire assembly 2 is small, and the core wire assembly 2 is prone to friction with the outer shell 12. If the radius corresponding to the arc surface is too large, the bending amplitude of the core wire assembly 2 is too large, and the core wire assembly 2 is easily damaged.

[0045] In some embodiments, the third surface 123 abuts against the core wire assembly 2, thereby making the core wire assembly 2 more stable. When the core wire assembly 2 shakes, the impact between the core wire assembly 2 and the third surface 123 is smaller, thus making the core wire assembly 2 less prone to damage. For example, the diameter of the core wire assembly 2 is the same as the diameter of the second opening 1221, or the diameter of the core wire assembly 2 is slightly larger than the diameter of the second opening 1221, thereby ensuring the stability of the core wire assembly 2 while avoiding excessive compression of the core wire assembly 2.

[0046] like Figure 4 As shown, in some embodiments, the inner wall of the receiving cavity 121 has a fourth surface 124 connected to the third surface 123. The fourth surface 124 is perpendicular to the third surface 123, meaning that the junction of the fourth surface 124 and the third surface 123 has a sharp ridge. This helps to improve the fit between the inner mold 13 and the fourth surface 124, thereby improving the sealing effect between the outer shell 12 and the inner mold 13, preventing dust from entering the receiving cavity 121, and making it less prone to dirt accumulation inside the receiving cavity 121. In addition, the perpendicularity of the fourth surface 124 to the third surface 123 also allows the outer shell 12 to limit the inner mold 13, making the inner mold 13 more securely positioned within the receiving cavity 121.

[0047] like Figure 5 As shown, in some embodiments of this application, the inner mold 13 and the outer shell 12 are connected by an adhesive, which may include glue. To make the connection between the outer shell 12 and the inner mold 13 more secure, the outer surface of the inner mold 13 is provided with an overflow groove 132 for receiving adhesive.

[0048] When assembling the inner mold 13 and the outer shell 12, adhesive can be applied to the overflow groove 132 and the inner surface of the outer shell 12. Then, the inner mold 13 is inserted into the receiving cavity 121 of the outer shell 12, and the adhesive securely connects the outer shell 12 and the inner mold 13. The overflow groove 132 can hold a large amount of adhesive, ensuring sufficient contact between the inner surface of the outer shell 12 and the outer surface of the inner mold 13. After the adhesive cures, it not only bonds to the inner mold 13 but also engages with the overflow groove 132, thereby increasing the connection strength between the adhesive and the inner mold 13.

[0049] The overflow groove 132 includes a first groove 1321 extending along a first direction and a second groove 1322 extending along a second direction. The first direction and the second direction intersect, and the first groove 1321 and the second groove 1322 are staggered.

[0050] The staggered arrangement of the first groove 1321 and the second groove 1322 can disperse the force to other directions and to more areas, thereby improving the stability of the bonding between the outer shell 12 and the inner mold 13.

[0051] In some embodiments of this application, a first groove 1321 and a second groove 1322 enclose a protrusion 133, and the number of protrusions 133 is multiple. That is, there are multiple first grooves 1321, which are evenly spaced, and there are multiple second grooves 1322, which are also evenly spaced. The multiple first grooves 1321 and the multiple second grooves 1322 enclose a multiple protrusion 133. The protrusion 133 is approximately cubic in shape and has four surfaces intersecting the insertion direction. When using the data cable 300, the direction of the tensile force on the inner mold 13 is often the same as the insertion direction. When the inner mold 13 is pulled by an external force, the four surfaces of the protrusion 133 will share the tensile force, improving the tensile strength of the inner mold 13 and preventing the inner mold 13 from being deformed or damaged by pulling.

[0052] In some embodiments, the angle between the first direction and the insertion direction is the same as the angle between the second direction and the insertion direction. Optionally, the angle between the first direction and the insertion direction can be 45 degrees, and the angle between the second direction and the insertion direction can also be 45 degrees. The four surfaces of the protrusion 133 can be evenly stressed, and excessive local stress on the protrusion 133 can be avoided as much as possible. In this way, the tensile strength of the inner mold part 13 can be further improved.

[0053] like Figure 6As shown, in some embodiments of this application, the inner wall of the outer shell 12 is provided with an annular groove 126 surrounding the insertion direction, and the surface of the inner mold 13 facing the outer shell 12 is provided with a protruding rib 131. The protruding rib 131 is inserted into the annular groove 126 to limit its movement relative to the outer shell 12 along the insertion direction, thereby improving the data cable's tensile strength. The protruding rib 131 can be arranged around the inner mold 13. Multiple protruding ribs 131 can also be provided, spaced apart circumferentially along the inner mold 13. The annular groove 126 can have the same shape as the outer shell 12. When the outer shell 12 is racetrack-shaped, the annular groove 126 can also be racetrack-shaped, preventing the inner mold 13 from rotating around the insertion direction.

[0054] Secondly, please refer to Figure 8 This application embodiment also provides a method for manufacturing a data cable 100, the data cable including a core wire assembly 2 and a braided layer 3, the braided layer 3 covering the outer surface of the core wire assembly 2.

[0055] The method includes:

[0056] Step S10: Apply the filler coating to the woven layer 3.

[0057] The filler coating can be applied to the braided layer 3 in a variety of ways, such as by immersing the braided layer 3 in the filler coating, spraying the filler coating onto the braided layer 3, or brushing the filler coating onto the braided layer 3.

[0058] Step S20: Bake the data cable 100 with the filler coating applied.

[0059] Baking can shorten the curing time of filler coatings and improve production efficiency. It should be noted that different coatings have different curing methods. The coating selected in this application embodiment requires a baking process, while some other coatings may not require a baking process.

[0060] In order to ensure that the filler coating is fully filled into the braided layer 3, the filler coating can be first placed in an oil immersion tank, and then the data cable 100 can be completely immersed in the oil immersion tank. The filler coating in the oil immersion tank will penetrate into the braided layer 3. After soaking for a period of time, the data cable 100 is taken out and finally baked. After heating, the filler coating will solidify and fill the inside of the braided layer 3 to form a filler layer 4, thereby preventing dust from entering the inside of the braided layer 3 as much as possible and enhancing the anti-pollution ability of the data cable 100.

[0061] It should be noted that during the manufacturing process of the data cable 100, a braided layer 3 can be first woven onto the core wire assembly 2, then a filler coating can be applied to the braided layer 3, and finally the core wire assembly 2 and the terminal assembly 1 can be soldered together. In this case, when the filler coating is applied to the braided layer 3, the data cable 100 temporarily does not include the terminal assembly 1. Alternatively, during the manufacturing process of the data cable 100, the core wire assembly 2 and the terminal assembly 1 can be soldered together first, then a braided layer 3 can be woven onto the core wire assembly 2, and finally a filler coating can be applied to the braided layer 3. In this case, when the filler coating is applied to the braided layer 3, the data cable 100 includes the terminal assembly 1.

[0062] In some embodiments, the filler coating comprises one or more of methyl vinyl siloxane, silica, hydrogen-containing silicone oil, and light white oil. Optionally, the filler coating comprises 25-35 parts by weight of methyl vinyl siloxane, 10-20 parts by weight of silica, 10-20 parts by weight of hydrogen-containing silicone oil, and 35-45 parts by weight of light white oil. For example, the filler coating comprises 25 parts by weight of methyl vinyl siloxane, 20 parts by weight of silica, 20 parts by weight of hydrogen-containing silicone oil, and 35 parts by weight of light white oil. Alternatively, the filler coating comprises 35 parts by weight of methyl vinyl siloxane, 10 parts by weight of silica, 10 parts by weight of hydrogen-containing silicone oil, and 45 parts by weight of light white oil. Alternatively, the filler coating comprises 30 parts by weight of methyl vinyl siloxane, 15 parts by weight of silica, 15 parts by weight of hydrogen-containing silicone oil, and 40 parts by weight of light white oil.

[0063] In some embodiments, the filler coating may further include 5-10 parts by weight of silicone varnish. For example, the filler coating may consist of 25 parts by weight of methyl vinyl siloxane, 20 parts by weight of silica, 15 parts by weight of hydrogen-containing silicone oil, and 35 parts by weight of light white oil, with 5 parts by weight of silicone varnish. Alternatively, the filler coating may consist of 30 parts by weight of methyl vinyl siloxane, 10 parts by weight of silica, 10 parts by weight of hydrogen-containing silicone oil, and 40 parts by weight of light white oil, with 10 parts by weight of silicone varnish. Alternatively, the filler coating may consist of 30 parts by weight of methyl vinyl siloxane, 11 parts by weight of silica, 14 parts by weight of hydrogen-containing silicone oil, and 37 parts by weight of light white oil, with 8 parts by weight of silicone varnish. Silicone varnish has a smooth feel and a matte finish, exhibiting excellent skin-friendly properties, further enhancing the usability of the data cable 100. Furthermore, silicone varnish also has anti-allergic effects, making it more user-friendly.

[0064] In some embodiments, baking the data cable 100 coated with the filler coating includes baking the soaked data cable 100 at a preset temperature for 2 to 3 hours to cure the filler coating. The preset temperature can be 180-220 degrees Celsius, for example, 180 degrees Celsius, 200 degrees Celsius, 220 degrees Celsius, etc. Silica has excellent high-temperature resistance, which can further improve the high-temperature resistance of the core wire assembly 2 and also prevent the filler coating from evaporating easily in an oven at 180-220 degrees Celsius. Heating and baking for 2 to 3 hours allows the filler coating to be heated more thoroughly, resulting in more complete curing and thus more securely filling the braided layer 3.
