[0022] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application and not to limit the present application.

[0023] Referring to FIGS. 1-2, the first aspect of the embodiments of the present application provides a data line 100, which comprises a terminal assembly 1, a core wire assembly 2, a braided layer 3 and a filling layer 4.

[0024] The terminal assembly 1 is configured to connect electronic devices, for example, the terminal assembly 1 is configured to connect mobile phones, tablets, notebook computers, desktop computers, chargers, etc. The type of the terminal assembly 1 can exemplarily be USB-A, USB-C, etc.

[0025] The core wire assembly 2 is connected with the terminal assembly 1, and the core wire assembly 2 is configured to conduct electricity, which can be configured to charge electronic devices, transmit data to electronic devices, or transmit data while charging. Generally, both ends of the core wire assembly 2 are provided with the terminal assembly 1, and the types of the two terminal assemblies can be the same or different.

[0026] The braided layer 3 covers the outer surface of the core wire assembly 2, and the material of the braided layer 3 can be nylon, etc. When the user pulls the data line 100, the braided layer 3 can bear part of the pulling force, thereby protecting the core wire assembly 2. The braided layer 3 not only enhances the durability of the data line 100, but also beautifies the appearance of the data line 100. The braided layer 3 can be a mesh structure woven by nylon threads, thereby improving the toughness and wear resistance of the data line 100.

[0027] It can be understood that, since the braided layer 3 is a silk fabric, the braided layer 3 has a plurality of braided gaps 31, which include the gaps between single threads. It can also be understood that, since the single threads can be woven by a plurality of finer threads, there are also gaps between the plurality of finer threads, so the plurality of braided gaps 31 also include the gaps inside the single threads. The filling layer 4 is filled in the plurality of braided gaps 31, thereby being closely combined with the braided layer 3. Optionally, the filling layer 4 is of a flexible and skin-friendly material, so that the data line 100 is relatively soft, can provide a better hand feeling, and has good bending resistance and is not easy to be damaged when being bent.

[0028] In the embodiments provided by the present application, the filling layer 4 is arranged in the plurality of braided gaps 31, and the filling layer 4 can be completely or partially filled in the braided gaps 31, so that dust and stains are difficult to deposit in the braided gaps 31. The filling layer 4 and the braided layer 3 together wrap the core wire assembly 2, which can prevent dust and stains from entering and being absorbed in the braided layer 3, prevent the data line 100 from accumulating dust, and thereby improve the dirt resistance of the data line 100.

[0029] Meanwhile, since the braided layer 3 is a silk fabric, for example, the material of the braided layer 3 is generally polyester, nylon or cotton thread, etc., the braided layer 3 is easy to pill. The filling layer 4 of the embodiment is closely combined with the braided layer 3, and the filling layer 4 can also protect the braided layer 3 to avoid the braided layer 3 from pilling as much as possible. In addition, the filling layer 4 can also improve the tensile strength of the data line 100 and improve the waterproof performance of the data line 100.

[0030] In some embodiments of the present application, the material of the filling layer 4 includes one or more of methyl vinyl silicone, silica, hydrogen-containing silicone oil and light white oil. Optionally, the material of the filling layer 4 includes methyl vinyl silicone 25-35 parts by mass, silica 10-20 parts by mass, hydrogen-containing silicone oil 10-20 parts by mass and light white oil 35-45 parts by mass. For example, the material of the filling layer 4 includes methyl vinyl silicone 25 parts by mass, silica 20 parts by mass, hydrogen-containing silicone oil 20 parts by mass and light white oil 35 parts by mass. Alternatively, the material of the filling layer 4 includes methyl vinyl silicone 35 parts by mass, silica 10 parts by mass, hydrogen-containing silicone oil 10 parts by mass and light white oil 45 parts by mass. Alternatively, the material of the filling layer 4 includes methyl vinyl silicone 30 parts by mass, silica 15 parts by mass, hydrogen-containing silicone oil 15 parts by mass and light white oil 40 parts by mass.

[0031] The hydrogen-containing silicone oil is an organic silicone oil, which has good lubricating performance and excellent hydrophobicity, can form a waterproof layer to prevent water from entering the braided gap 31 and avoid interference with the core wire assembly 2. The methyl vinyl silicone not only has good lubricating performance and waterproof performance, but also has adhesion, which can firmly connect the filling layer 4 to the braided layer 3. In addition, the methyl vinyl silicone also has excellent sealing performance, which can avoid the gap between the filling layer 4 and the braided layer 3 that allows dust to enter, and can make the data line 100 more resistant to dirt. Among them, the methyl vinyl silicone, the hydrogen-containing silicone oil and the light white oil all have lubricating performance, which can not only improve the dirt resistance of the data line 100, but also can avoid the data line 100 from having a rough surface, thereby avoiding the data line 100 from pilling.

[0032] In some embodiments, the material of the filling layer 4 can further include silicone paint 5-10 parts by mass. For example, the material of the filling layer 4 includes methyl vinyl silicone 25 parts by mass, silica 20 parts by mass, hydrogen-containing silicone oil 15 parts by mass, and light white oil 35 parts by mass, and silicone paint 5 parts by mass. Alternatively, the material of the filling layer 4 includes methyl vinyl silicone 30 parts by mass, silica 10 parts by mass, hydrogen-containing silicone oil 10 parts by mass, and light white oil 40 parts by mass, and silicone paint 10 parts by mass. Alternatively, the material of the filling layer 4 includes methyl vinyl silicone 30 parts by mass, silica 11 parts by mass, hydrogen-containing silicone oil 14 parts by mass, and light white oil 37 parts by mass, and silicone paint 8 parts by mass. The silicone paint has the characteristics of smooth hand feeling and matte surface, has excellent skin-friendly properties, and can further improve the use of the data cable 100. Moreover, the silicone paint also has the effect of anti-allergy, which is more friendly to users.

[0033] It should be noted that the dirt-resistant function of the data cable 100 described above is achieved by filling the filling layer 4 with hydrophobic function in the weaving gap 31 of the weaving layer 3, and therefore the material of the filling layer 4 includes but is not limited to the above-mentioned formula. In some embodiments, the material of the filling layer 4 can also include other nano-coatings with hydrophobic function, which can be immersed in the gap of the weaving layer, and after the coating is cured, it also has the function of resisting dirt.

[0034] In some embodiments of the present application, the core wire assembly 2 includes a core wire 23, a shielding layer 22, and an insulating layer 21.

[0035] The core wire 23 can be provided to be conductive, and the core wire 23 exemplarily includes a plurality of fine wires, and the number of the plurality of fine wires can be different according to the type of the terminal assembly 1.

[0036] The shielding layer 22 covers the core wire 23, and the shielding layer 22 can prevent external electromagnetic interference from affecting the signals transmitted by the core wire 23. The electromagnetic interference can come from other electronic devices, power lines, or other wireless signal sources, which can interfere with the weak signals transmitted in the data cable 100, causing data transmission errors or performance degradation of the data cable 100. The shielding layer 22 can effectively guide these interference signals to the ground by providing a conductive barrier, thereby protecting the signals transmitted by the internal core wire 23 from being affected. Moreover, the shielding layer 22 can also reduce signal radiation.

[0037] The material of the shielding layer 22 can include graphene material. The graphene shielding layer 22 can provide effective electromagnetic shielding in a wide frequency range, with good shielding effect from low frequency to high frequency. The graphene material can also be combined with other materials to make a flexible shielding layer 22, improving the softness of the data line 100. The graphene material can be made into a very thin single-layer or few-layer structure, which helps to reduce the weight and volume of the core wire assembly 2 of the data line 100 while maintaining the electromagnetic shielding effect. The shielding layer 22 can also coat the plurality of nylon wire 24, which can improve the overall toughness of the data line 100.

[0038] The insulating layer 21 covers the shielding layer 22. The insulating layer 21 can provide insulation effect to prevent the core wire 23 from leaking electricity. The insulating layer 21 is wrapped outside the shielding layer 22, which can protect the data line 100 from external environment (such as moisture, dirt, etc.), and can fix the core wire 23. The insulating layer 21 can also provide a certain degree of physical protection to prevent the core wire 23 and the shielding layer 22 from being mechanically damaged. The material of the insulating layer 21 includes one or more of silicone, thermoplastic elastomer, Teflon, Hytrel or modified polypropylene. Among them, silicone, thermoplastic elastomer, Teflon, Hytrel and modified polypropylene are all high-temperature resistant materials, which can make the data line 100 able to withstand high-temperature environment. It should be noted that since the coating and filling layer 4 needs to use the baking process, the insulating layer 21 of the embodiment of the present application is made of high-temperature resistant material, so that the insulating layer 21 can withstand the high temperature of the baking process when the coating and filling layer 4 is applied.

[0039] As shown in FIG. 3, in some embodiments of the present application, the terminal assembly 1 includes a connecting terminal 11, an inner module 13 and a shell 12.

[0040] The connecting terminal 11 is connected with the core wire assembly 2. The connecting terminal 11 has a plug-in direction, which is the direction when the connecting terminal 11 is plugged with the electronic device. The connecting terminal 11 can be a male or female port.

[0041] The inner module 13 covers the connection between the connecting terminal 11 and the core wire assembly 2. The inner module 13 can be a plastic inner film, which is formed at the connection between the connecting terminal 11 and the core wire assembly 2 by injection molding, so that the inner module 13 has low cost and good insulation, which can ensure the insulation effect of the connection between the core wire assembly 2 and the connecting terminal 11, thereby avoiding safety hazards such as short circuit or electric shock as much as possible. Moreover, the inner module 13 can seal the connection between the core wire assembly 2 and the connecting terminal 11, which can improve the strength of the connection between the connecting terminal 11 and the core wire assembly 2, and improve the waterproof effect of the connection between the connecting terminal 11 and the core wire assembly 2, on the one hand, and help to reduce electromagnetic interference and radio frequency interference, and improve the stability and accuracy of data transmission of the core wire assembly 2.

[0042] As shown in FIG. 4, the shell 12 has a receiving cavity 121, and the inner module 13 is arranged in the receiving cavity 121, and the shell 12 can protect the inner module 13. The material of the shell 12 is exemplarily an aluminum alloy material, so that the shell 12 has high strength, long service life, and good heat dissipation performance. The outer wall of the shell 12 has a first surface 125 and a second surface 122 arranged oppositely in the plug-in direction, the first surface 125 is provided with a first opening 1251 through which the connecting terminal 11 passes, that is, the first opening 1251 is communicated with the receiving cavity 121, and the connecting terminal 11 can pass through the first opening 1251 and be connected with the electronic device. The second surface 122 is provided with a second opening 1221 through which the core wire assembly 2 passes, that is, the second opening 1221 is communicated with the receiving cavity 121, and the core wire assembly 2 can pass through the second opening 1221 and be connected 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, that is, the surface of the shell 12 opposite to the core wire assembly 2 at the second opening 1221 is the third surface 123, and the section of the junction of the third surface 123 and the second surface 122 is a curved surface. Compared with the junction of the third surface 123 and the second surface 122 being commonly provided with a sharp edge line, the sharp edge of the shell 12 can cut the data line 100, and the data line 100 can be damaged. The section of the junction of the third surface 123 and the second surface 122 in the embodiment of the application is a curved surface, the contact area of the curved surface with the core wire assembly 2 is larger, and the pressure of the shell 12 on the core wire assembly 2 is smaller, so that the local wear of the core wire assembly 2 by the shell 12 is reduced, and the data line 100 is prevented from being cut by the shell 12 as much as possible.

[0043] It also needs to be explained that, in order to solve the problem that the connection between the core wire assembly 2 and the shell 12 is easy to be damaged, a stress relief sleeve made of a rigid material is usually arranged at the end of the core wire assembly 2.

[0044] The data line 100 of the application is provided with the braided layer 3 and the filling layer 4 on one hand, and the curved surface is arranged at the junction of the third surface 123 and the second surface 122 on the other hand, so that the strength of the core wire assembly 2 is improved, the core wire assembly 2 is not easy to be damaged, the stress concentration is reduced, the data line 100 can have a long service life without the stress relief sleeve, and the structure of the data line is simpler.

[0045] As shown in FIG. 4 and FIG. 7, in some embodiments, the cross section of the junction between the third surface 123 and the second surface 122 is an arc surface, which facilitates processing. The arc surface can also provide more space for the core wire assembly 2 to bend, so that the contact area between the core wire assembly 2 and the shell 12 is small when the core wire assembly 2 is bent, thereby avoiding damage to the core wire assembly 2 and prolonging the service life of the data cable 100. When the core wire assembly 2 is bent, the arc surface can limit the bending amplitude of the core wire assembly 2, so that the bending amplitude of the core wire assembly 2 is more uniform, and damage to the core wire assembly 2 is avoided. 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 bendable amplitude of the core wire assembly 2 is small, and the core wire assembly 2 is prone to rubbing against the shell 12. If the radius corresponding to the arc surface is too small, the bendable amplitude of the core wire assembly 2 is too large, and the core wire assembly 2 is prone to damage.

[0046] In some embodiments, the third surface 123 abuts the core wire assembly 2, so that the core wire assembly 2 is more stable, and when the core wire assembly 2 is shaken, the impact between the core wire assembly 2 and the third surface 123 is small, so that the core wire assembly 2 is not easily damaged. 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, so as to ensure the stability of the core wire assembly 2 and avoid excessive compression of the core wire assembly 2.

[0047] As shown in FIG. 4, in some embodiments, the inner wall of the accommodating cavity 121 has a fourth surface 124 connected with the third surface 123, and the fourth surface 124 is arranged perpendicularly to the third surface 123, that is, the junction between the fourth surface 124 and the third surface 123 has a sharp edge line, which facilitates improving the fit of the inner mold 13 and the fourth surface 124, thereby improving the sealing effect between the shell 12 and the inner mold 13, preventing dust from entering the accommodating cavity 121, and preventing the accommodating cavity 121 from being easily contaminated. In addition, the perpendicular arrangement of the fourth surface 124 and the third surface 123 can also limit the inner mold 13 in the shell 12, so that the inner mold 13 is more stably located in the accommodating cavity 121.

[0048] As shown in FIG. 5, in some embodiments of the present application, the inner mold 13 and the shell 12 are connected by an adhesive, which can include glue. In order to make the connection between the shell 12 and the inner mold 13 more stable, the outer surface of the inner mold 13 is provided with a glue overflow groove 132 for accommodating the adhesive.

[0049] When assembling the inner module 13 and the outer shell 12, adhesive can be applied in the overflow groove 132 and on the inner surface of the outer shell 12, and then the inner module 13 is inserted into the accommodating cavity 121 of the outer shell 12, so that the outer shell 12 and the inner module 13 are stably connected by the adhesive. The overflow groove 132 can accommodate more adhesive, so that the inner surface of the outer shell 12 and the outer surface of the inner module 13 are fully in contact with the adhesive. After the adhesive solidifies, the adhesive not only bonds with the inner module 13, but also can be clamped with the overflow groove 132, so as to improve the connection strength of the adhesive and the inner module 13.

[0050] The overflow groove 132 includes a first groove 1321 extending in a first direction and a second groove 1322 extending in a second direction, the first direction intersects the second direction, and the first groove 1321 and the second groove 1322 are staggered.

[0051] The staggered first groove 1321 and the second groove 1322 can disperse the stress to other directions and more areas, thereby improving the stability of the bonding between the outer shell 12 and the inner module 13.

[0052] In some embodiments of the present application, the first groove 1321 and the second groove 1322 enclose a protrusion 133, and the number of the protrusions 133 is multiple. That is, the number of the first grooves 1321 is multiple, the multiple first grooves 1321 are uniformly spaced, the number of the second grooves 1322 is multiple, the multiple first grooves 1321 are uniformly spaced, and the multiple first grooves 1321 and the multiple second grooves 1322 enclose multiple protrusions 133. The shape of the protrusion 133 is approximately a cube, and the protrusion 133 has four surfaces intersecting the insertion direction. When the data line 300 is used, the direction of the pulling force on the inner module 13 is often the same as the insertion direction. When the inner module 13 is pulled by external force, the four surfaces of the protrusion 133 will jointly bear the pulling force, thereby improving the anti-pulling ability of the inner module 13, and avoiding deformation or damage of the inner module 13.

[0053] 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. Alternatively, 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 uniformly stressed, so as to avoid excessive local stress of the protrusion 133, thereby further improving the anti-pulling ability of the inner module 13.

[0054] As shown in FIG. 6, in some embodiments of the present application, the inner wall of the outer shell 12 is provided with a ring groove 126 around the plug-in direction, and the inner module 13 is provided with a convex rib 131 towards the surface of the outer shell 12, the convex rib 131 is inserted into the ring groove 126 to limit the position with the ring groove 126, so as to limit the movement of the convex rib 131 relative to the outer shell 12 along the plug-in direction to some extent, thereby improving the anti-pulling effect of the data line. Wherein, the convex rib 131 can be arranged around the inner module 13. The convex rib 131 can also be provided as a plurality of convex ribs 131, which are arranged at intervals along the circumference of the inner module 13. The ring groove 126 can be the same shape as the outer shell 12, and when the outer shell 12 is in the shape of a racetrack, the ring groove 126 can also be in the shape of a racetrack, which can prevent the inner module 13 from rotating around the plug-in direction.

[0055] In a second aspect, referring to FIG. 8, the present application also provides a manufacturing method of a data line 100, which comprises a core wire assembly 2 and a braided layer 3, and the braided layer 3 covers the outer surface of the core wire assembly 2.

[0056] The method comprises:

[0057] In step S10, the filling paint is attached to the braided layer 3.

[0058] The filling paint can be attached to the braided layer 3 in various ways, for example, the braided layer 3 can be soaked in the filling paint, or the filling paint can be sprayed on the braided layer 3, or the filling paint can be brushed on the braided layer 3.

[0059] In step S20, the data line 100 with the attached filling paint is baked.

[0060] Baking can shorten the curing time of the filling paint and improve production efficiency. It should be noted that different coatings have different curing methods. The coating selected in the present application needs baking process, while some other coatings may not need baking process.

[0061] In order to make the filling paint fully filled in the braided layer 3, the filling paint can be first contained in an oil immersion tank, and then the data line 100 is completely immersed in the oil immersion tank. The filling paint in the oil immersion tank will penetrate into the braided layer 3. After soaking for a period of time, the data line 100 is taken out, and finally the data line 100 after soaking is baked. The filling paint will be cured and filled in the braided layer 3 after heating to form a filling layer 4, thereby preventing dust from entering the braided layer 3 as much as possible and enhancing the anti-pollution ability of the data line 100.

[0062] It should be noted that in the process of manufacturing the data cable 100, the braided layer 3 can be braided on the core cable assembly 2 first, then the filling paint is attached on the braided layer 3, and finally the core cable assembly 2 is welded and assembled with the terminal assembly 1, so that the data cable 100 does not include the terminal assembly 1 temporarily when the filling paint is attached on the braided layer 3. Alternatively, in the process of manufacturing the data cable 100, the core cable assembly 2 can be welded and assembled with the terminal assembly 1 first, then the braided layer 3 is braided on the core cable assembly 2, and finally the filling paint is applied on the braided layer 3, so that the data cable 100 includes the terminal assembly 1 when the filling paint is attached on the braided layer 3.

[0063] In some embodiments, the material of the filling paint includes one or more of methyl vinyl silicone, silica, hydrogen-containing silicone oil, and light white oil. Alternatively, the material of the filling paint includes methyl vinyl silicone 25-35 parts by mass, silica 10-20 parts by mass, hydrogen-containing silicone oil 10-20 parts by mass, and light white oil 35-45 parts by mass. For example, the material of the filling paint includes methyl vinyl silicone 25 parts by mass, silica 20 parts by mass, hydrogen-containing silicone oil 20 parts by mass, and light white oil 35 parts by mass. Alternatively, the material of the filling paint includes methyl vinyl silicone 35 parts by mass, silica 10 parts by mass, hydrogen-containing silicone oil 10 parts by mass, and light white oil 45 parts by mass. Alternatively, the material of the filling paint includes methyl vinyl silicone 30 parts by mass, silica 15 parts by mass, hydrogen-containing silicone oil 15 parts by mass, and light white oil 40 parts by mass.

[0064] In some embodiments, the material of the filling paint can further include silicone paint 5-10 parts by mass. For example, the material of the filling paint includes methyl vinyl silicone 25 parts by mass, silica 20 parts by mass, hydrogen-containing silicone oil 15 parts by mass, and light white oil 35 parts by mass, and silicone paint 5 parts by mass. Alternatively, the material of the filling paint includes methyl vinyl silicone 30 parts by mass, silica 10 parts by mass, hydrogen-containing silicone oil 10 parts by mass, and light white oil 40 parts by mass, and silicone paint 10 parts by mass. Alternatively, the material of the filling paint includes methyl vinyl silicone 30 parts by mass, silica 11 parts by mass, hydrogen-containing silicone oil 14 parts by mass, and light white oil 37 parts by mass, and silicone paint 8 parts by mass. The silicone paint has the characteristics of smooth hand feeling and matte surface, has excellent skin-friendly properties, and can further improve the use of the data cable 100. Moreover, the silicone paint also has the effect of anti-allergy, which is more friendly to users.

[0065] In some embodiments, baking the data line 100 with the filling coating attached includes baking the soaked data line 100 at a preset temperature for 2-3 hours, so that the filling coating is cured. The preset temperature can be 180-220 degrees Celsius, for example, 180 degrees Celsius, 200 degrees Celsius, 220 degrees Celsius, etc. Among them, silicon dioxide has excellent high temperature resistance, which can further improve the high temperature resistance of the core wire assembly 2, and also makes the filling coating not easy to volatilize in the 180-220 degree oven. Heating and baking for 2-3 hours can make the filling coating heat more fully, so that the filling coating is more fully cured, and then the filling coating is more stably filled in the braided layer 3.
