[0002] With the development of science and technology, various electronic devices have begun to appear, providing convenience for people's production and life. Among them, electronic devices need cables to transmit current and transmit electrical signals. For example, the cables on mobile phone data cables can be used to charge mobile phones and transmit data.

[0003] Currently, cables are often subjected to external forces such as pulling and bending during use, which can easily lead to fatigue fractures and make them unusable. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] After long-term research, the inventors found that electronic devices need cables to transmit current and electrical signals. For example, the cables on mobile phone data cables can be used to charge mobile phones and transmit data. At present, cables are often subjected to external forces such as pulling and bending during use, so they are prone to fatigue fracture and cannot be used. In order to solve this technical problem, the present application provides the following embodiments.

[0023] like Figures 1 to 5 As shown, the cable 10 described in the cable embodiment of the present application includes a sub-cable 100 and at least one reinforcement structure 200, and the sub-cable 100 has a conductive conductor part 110. Each reinforcement structure 200 includes a fiber part 201 and at least one metal part 202, the fiber part 201 extends along the extension direction of the sub-cable 100, and the at least one metal part 202 spirally extends along the extension direction of the fiber part 201 and surrounds the outer periphery of the fiber part 201.

[0024] The cable 10 is often subjected to external forces such as pulling and bending during use, so that the conductor part 110 inside the cable 10 is prone to fatigue fracture and cannot be used. By providing the reinforcement structure 200, the risk of fatigue fracture of the conductor part 110 can be reduced, and the ability of the cable 10 to resist fatigue fracture can be enhanced.

[0025] Specifically, the fiber part 201 has a high tensile strength. By setting the fiber part 201 to extend along the extension direction of the sub-cable 100, the fiber part 201 can share the tensile stress of the conductor part 110 when the cable 10 is pulled or bent, and the tensile stress of the conductor part 110 is small, thereby increasing the number of times the conductor part 110 can withstand the stretching and bending effects, so that the conductor part 110 is not easily broken. By setting at least one metal part 202 to extend spirally along the extension direction of the fiber part 201, the metal part 202 can have a large deformation margin, be easy to bend and deform, be subjected to small shear force when bending, and have small resistance to the bending of the cable 10, which is conducive to maintaining the soft and easy-to-bend characteristics of the cable 10. When the cable 10 is bent, the metal part 202 can reduce the occurrence of stress concentration on the conductor part 110, reduce the probability of generating breakpoints on the conductor part 110, and make the conductor part 110 not easily broken due to bending.

[0026] The metal part 202 is spirally wound around the outer circumference of the fiber part 201, which is beneficial for the relative fixation of the metal part 202 and the limiting part, so that the reinforcement structure 200 exists as an integral structure. During the production process of the cable 10, it is convenient to introduce the reinforcement structure 200 into the cable 100, thereby improving production efficiency.

[0027] Alternatively, if Figure 3 and Figure 4As shown, the two metal parts 202 extend spirally along the extending direction of the fiber part 201 and surround the outer circumference of the fiber part 201. The winding directions of the two metal parts 202 can be the same or opposite.

[0028] Optionally, the metal part 202 is made of copper, aluminum, stainless steel or other alloy materials.

[0029] Optionally, the fiber portion 201 includes at least one of nylon fiber, PET fiber, aramid fiber, and PE fiber.

[0030] Optionally, the conductor part 110 may be one of a ground conductor and a core conductor. The ground conductor is used for grounding, and the core conductor is used for transmitting electric energy and electric signals.

[0031] Alternatively, if Figure 1 and Figure 6 As shown, a plurality of reinforcement structures 200 surround the outer circumference of at least one sub-cable 100 to form a protective layer 210. The plurality of reinforcement structures 200 are arranged side by side so that the cross section of the protective layer 210 along the direction perpendicular to the axis of the sub-cable 100 is an annular structure.

[0032] By arranging multiple reinforcement structures 200 to surround the outer circumference of at least one sub-cable 100, the multiple reinforcement structures 200 can protect the sub-cable 100 inside the protective layer 210 in multiple directions. When the sub-cable 100 is pulled or bent in different directions, the protective layer 210 can protect the sub-cable 100, thereby improving the protection effect of the sub-cable 100 inside the protective layer 210 and reducing the risk of fatigue fracture of the conductor part 110.

[0033] Furthermore, a plurality of reinforcing structures 200 may be arranged along the circumference of the sub-cable 100 so as to abut against each other, thereby increasing the arrangement density of the reinforcing structures 200 and improving the protection effect on the sub-cable 100 .

[0034] Optionally, the protective layer 210 may surround a single sub-cable 100 or more than two sub-cables 100, and one protective layer 210 or at least two protective layers 210 may be provided in the cable 10. Different protective layers 210 may be provided independently of each other or may be nested with each other.

[0035] Optionally, each reinforcement structure 200 is wound around at least one sub-cable 100 along the extension direction of the sub-cable 100. Further, each reinforcement structure 200 is spirally extended along the extension direction of the sub-cable 100 and is wound around at least one sub-cable 100.

[0036] That is, the reinforcing structure 200 has a two-stage spiral structure, that is, on the basis of the metal part 202 spirally wrapping around the outer periphery of the fiber part 201 along the extension direction of the fiber part 201, the metal part 202 and the fiber part 201 spirally extend along the extension direction of the sub-cable 100 and are wound on the sub-cable 100. Such a configuration can achieve a preliminary fixation of the reinforcing structure 200 on the sub-cable 100 after being wound on the sub-cable 100, and prevent the reinforcing structure 200 from falling off from the sub-cable 100, which is conducive to improving the stability of the cable 10 production process.

[0037] Alternatively, if Figure 1 and Figure 7 As shown, the sub-cables 100 are all located in the annular structure formed by the protective layer 210. That is, there is a protective layer 210 in the cable 10 surrounding all the sub-cables 100 of the cable 10. In this way, the protective layer 210 can protect all the sub-cables 100 of the cable 10, which is conducive to improving the overall protection effect of the cable 10.

[0038] For example, the cable 10 may include 6 or 7 sub-cables 100 , and the 6 or 7 sub-cables 100 are all located in the annular structure formed by the protective layer 210 .

[0039] Alternatively, if Figures 8 to 10 As shown, at least one of the sub-cables 100 is located in the annular structure formed by the protective layer 210, and at least one other is located outside the protective layer 210. In other words, a protective layer 210 surrounds part of the sub-cables 100 of the cable 10 in the cable 10. In this way, the protective layer 210 can provide enhanced protection for the sub-cables 100 that are easily broken.

[0040] For example, Figure 8 As shown, the cable 10 may include 7 sub-cables 100 and a protective layer 210, 4 sub-cables 100 are located in the ring structure formed by the protective layer 210, and 3 sub-cables 100 are located outside the protective layer 210. For another example, Fig. 9 As shown, the cable 10 may include 6 sub-cables 100 and two protective layers 210, wherein two sub-cables 100 are arranged in the ring structure formed by each protective layer 210, and the remaining two sub-cables 100 are located outside the two protective layers 210. Fig.10 As shown, the cable 10 may include seven sub-cables 100 and three protective layers 210 , three sub-cables 100 are respectively located in the ring structure formed by the three protective layers 210 , and the remaining four sub-cables 100 are located outside the protective layers 210 .

[0041] In some embodiments, the cable 10 may include at least two protective layers 210, wherein all sub-cables 100 and the remaining protective layers 210 are disposed in a ring structure formed by one of the at least two protective layers 210, and at least one sub-cable 100 is disposed in each of the ring structures formed by the remaining protective layers 210. Figure 7 As shown, the cable 10 may include 7 sub-cables 100 and two protective layers 210 , wherein a sub-cable 100 is disposed in the annular structure formed by one of the protective layers 210 , and the 7 sub-cables 100 and one of the protective layers 210 are both located in the annular structure formed by the other protective layer 210 .

[0042] Alternatively, if Figure 1 and Figure 6 As shown, the cable 10 further includes an encapsulation layer 300, which surrounds the outer periphery of the protective layer 210. By providing the encapsulation layer 300, the protective layer 210 can be stably fixed to the outer periphery of the sub-cable 100, which is conducive to improving the stability of the production process. For example, the protective layer 210 can be a film wrapping tape or a plastic injection molding layer. Further, the encapsulation layer 300 can have an insulating effect.

[0043] Furthermore, the cable 10 may include at least two protective layers 210 and one packaging layer 300, and the packaging layer 300 surrounds the outer periphery of one of the protective layers 210. Alternatively, the number of packaging layers 300 and the number of protective layers 210 are the same and correspond one to one, and each packaging layer 300 surrounds the outer periphery of the corresponding protective layer 210.

[0044] Alternatively, if Figure 1 As shown, the cable 10 includes a shielding layer 400, which surrounds the outer circumference of at least one sub-cable 100. The shielding layer 400 surrounds the outer circumference of the protective layer 210.

[0045] The shielding layer 400 can reflect and absorb electromagnetic radiation, and can limit interference signals from entering the shielding layer 400, so as to reduce the loss of the signal transmitted by the sub-cable 100 inside the shielding layer 400. The shielding layer 400 can also protect the sub-cable 100, and reduce the risk of fatigue fracture of the sub-cable 100.

[0046] Optionally, the shielding layer 400 is located in the annular structure formed by the protective layer 210. In some embodiments, the shielding layer 400 surrounds the periphery of a single sub-cable 100 to limit mutual interference between the sub-cables 100. In some embodiments, the shielding layer 400 surrounds the periphery of all sub-cables 100 to limit interference of external signals on the sub-cables 100.

[0047] Optionally, the cable 10 includes two or more shielding layers 400 .

[0048] Alternatively, if Fig. 9 As shown, the shielding layer 400 includes shielding wires 401 and reinforcement structures 200 arranged along the circumference of the shielding layer 400. In the shielding layer 400, the ratio of the number of reinforcement structures 200 to the number of shielding wires 401 ranges from 5% to 10%.

[0049] The shielding wire 401 is made of metal or plastic with a metal coating. The shielding wire 401 can extend along the extension direction of the cable 10 or the sub-cable 100. The shielding wires 401 along the circumference of the shielding layer 400 abut against each other to achieve a dense arrangement, which can enhance the shielding effect of the interference signal. By providing the reinforcement structure 200 in the shielding layer 400, it is beneficial to improve the protection effect of the sub-cable 100.

[0050] Since the metal part 202 extends in a spiral shape, the reinforcing structure 200 itself has more gaps, and the shielding effect of the reinforcing structure 200 is weaker than that of the shielding wire 401. Therefore, the number of reinforcing structures 200 on the shielding layer 400 should not be too high, and the ratio of the number of reinforcing structures 200 to the number of shielding wires 401 should not exceed 10%. Too few reinforcing structures 200 on the shielding layer 400 will affect the protection effect, so the ratio of the number of reinforcing structures 200 to the number of shielding wires 401 should not be less than 5%.

[0051] For example, in the shielding layer 400 , the ratio of the number of the reinforcement structure 200 to the number of the shielding wires 401 is in the range of 2% or 5%.

[0052] Alternatively, if Figure 8 As shown, there are at least two sub-cables 100 , and the reinforcement structure 200 is located in the gap between the sub-cable 100 and the shielding layer 400 as a first filling component 220 , and the first filling component 220 and the sub-cable 100 are twisted into one.

[0053] The diameter of the sub-cable 100 may be greater than the diameter of the reinforcement structure 200. Different sub-cables 100 may be twisted together, and there is a gap between the twisted sub-cable 100 and the shielding layer 400. By arranging the reinforcement structure 200 at the position of the gap and twisting it together with the sub-cable 100, the reinforcement structure 200 can protect the sub-cable 100, which is conducive to improving the space utilization inside the cable 10.

[0054] Optionally, in the cable 10 , the first filling component 220 and the sub-cable 100 may also be twisted together with a filling material (such as fiber, soft cotton thread, etc.) to reduce the risk of fatigue fracture of the conductor part 110 .

[0055] Alternatively, if Figure 1 and Figure 7As shown, the number of sub-cables 100 is at least three, and the reinforcement structures 200 are scatteredly arranged between the sub-cables 100 as second filling components 230 , and the second filling components 230 and the sub-cables 100 are twisted together.

[0056] The diameter of the sub-cable 100 may be greater than the diameter of the reinforcing structure 200. Different sub-cables 100 may be twisted together, and there are gaps between the twisted sub-cables 100. By arranging the reinforcing structure 200 at the position of the gap and twisting it together with the sub-cable 100, the reinforcing structure 200 may protect the sub-cable 100, which is beneficial to improving the space utilization inside the cable 10.

[0057] Alternatively, if Figure 1 and Figure 7 As shown, at least three sub-cables 100 are spirally extended along the extension direction of the cable 10 to form a spiral battery core structure (not marked). At least three sub-cables 100 are arranged in sequence along the extension direction perpendicular to the cable 10, so that the cross-section of the battery core structure along the extension direction perpendicular to the cable 10 is annular. The reinforcement structure 200 is scattered between the sub-cables 100 in the battery core structure.

[0058] Specifically, at least three sub-cables 100 are twisted to extend spirally along the extension direction of the cable 10 to form a spiral battery core structure. By arranging at least three sub-cables 100 in sequence perpendicular to the extension direction of the cable 10, sufficient deformation space can be provided between different sub-cables 100, so that different sub-cables 100 can be twisted together.

[0059] Optionally, in the cable 10 , the second filling component 230 and the sub-cable 100 may also be twisted together with a filling material (such as fiber, soft cotton thread, etc.) to reduce the risk of fatigue fracture of the conductor part 110 .

[0060] Alternatively, if Fig.11 As shown, the sub-cable 100 further includes an insulating layer 120 surrounding the conductor portion 110. The conductor portion 110 includes a plurality of conductor wires 111. The reinforcement structure 200 is arranged between the plurality of conductor wires 111. By providing the insulating layer 120, short-circuit contact between different sub-cables 100 can be prevented. The insulating layer 120 can also protect the sub-cable 100 and reduce the risk of fatigue fracture of the sub-cable 100.

[0061] The conductor wire 111 is often subjected to external forces such as pulling and bending during use, and is prone to fatigue fracture and cannot be used. By providing a reinforcement structure 200 inside the sub-cable 100, the risk of fatigue fracture of the conductor wire 111 can be reduced and the ability of the conductor wire 111 to resist fatigue fracture can be enhanced.

[0062] Specifically, the fiber portion 201 of the reinforcement structure 200 has a high tensile strength. When the conductor line 111 is pulled or bent, the fiber portion 201 can share the tensile stress of the conductor line 111. The tensile stress of the conductor line 111 is small, thereby increasing the number of times the conductor line 111 can withstand the stretching and bending effects, making it difficult for the conductor line 111 to be broken. In addition, the metal portion 202 of the reinforcement structure 200 has a large deformation margin, is easy to bend and deform, and is subject to a small shear force when bending. When the conductor line 111 is bent, the metal portion 202 can reduce the occurrence of stress concentration on the conductor line 111, reduce the probability of generating breakpoints on the conductor line 111, and make it difficult for the conductor line 111 to break due to bending.

[0063] Alternatively, if Fig.12 As shown, a plurality of reinforcement structures 200 surround the outer periphery of the conductor portion 110 to form an inner protection layer 240 , and the insulation layer 120 surrounds the outer periphery of the inner protection layer 240 .

[0064] By arranging multiple reinforcement structures 200 to surround the outer circumference of the conductor part 110, the multiple reinforcement structures 200 can protect the conductor part 110 inside the inner protective layer 240 in multiple directions. When the conductor part 110 is pulled or bent in different directions, the inner protective layer 240 can protect the conductor part 110, thereby improving the protection effect of the conductor part 110 and reducing the risk of fatigue fracture of the conductor part 110.

[0065] Furthermore, a plurality of reinforcing structures 200 may be arranged along the circumference of the conductor portion 110 so as to abut against each other, thereby increasing the arrangement density of the reinforcing structures 200 and improving the protection effect on the conductor portion 110 .

[0066] Optionally, there are multiple sub-cables 100 , wherein the insulating layer 120 is disposed on the periphery of the conductor portion 110 of at least one sub-cable 100 , and the insulating layer 120 is not disposed on the periphery of the conductor portion 110 of at least another sub-cable 100 .

[0067] In other embodiments, the conductor portion 110 is a single copper wire or a single copper wire with a coating, such as a tinned copper wire, a silver-plated copper wire, etc.

[0068] Optionally, the conductor wire 111 is a thin copper wire or a thin copper wire with a coating, such as a tin-plated copper wire, a silver-plated copper wire, etc.

[0069] Optionally, in the sub-cable 100 , the ratio of the number of the reinforcement structure 200 to the number of the conductor wires 111 is 1% to 10%.

[0070] Since the metal part 202 extends in a spiral shape and has a large bending degree, the ability of the metal part 202 to transmit current or electrical signals is weaker than that of the conductor line 111. Therefore, the number of reinforcement structures 200 added to the sub-cable 100 should not be too high, and the ratio of the number of reinforcement structures 200 to the number of conductor lines 111 should not exceed 10%. Too few reinforcement structures 200 in the sub-cable 100 will affect the protection effect, so the ratio of the number of reinforcement structures 200 to the number of conductor lines 111 should not be less than 1%.

[0071] For example, in the sub-cable 100 , the ratio of the number of the reinforcement structure 200 to the number of the conductor wires 111 is 2% or 5%.

[0072] Optionally, in the sub-cable 100 , the reinforcement structure 200 and the conductor wire 111 may be twisted together with a filling material (eg, nylon fiber, etc.) to reduce the risk of fatigue fracture of the conductor part 110 .

[0073] Alternatively, if Figure 4 As shown, perpendicular to the extension direction of the metal part 202 , the cross section of the metal part 202 is a circular structure, and the diameter dimension D1 of the circular structure ranges from 0.03 mm to 0.20 mm.

[0074] Further, the diameter size D1 of the circular structure ranges from 0.05 mm to 0.15 mm. For example, the diameter size D1 of the circular structure ranges from 0.06 mm to 0.10 mm.

[0075] Such a configuration can not only ensure that the metal portion 202 has sufficient mechanical strength, but also reduce the radial dimension of the reinforcement structure 200 so as not to occupy too much space in the sub-cable 100 .

[0076] Alternatively, if Figure 2 As shown, perpendicular to the extension direction of the metal part 202, the cross section of the metal part 202 is a flat structure, the width dimension L1 of the flat structure ranges from 0.1mm to 1.0mm, and the thickness dimension L2 of the flat structure ranges from 0.01mm to 0.1mm. For example, the width dimension L1 of the flat structure is 0.2mm or 0.6mm, and the thickness dimension L2 of the flat structure is 0.02mm, 0.05mm or 0.07mm. Further, the thickness direction D2 of the flat structure is perpendicular to the extension direction of the fiber part 201.

[0077] The width dimension L1 of the flat structure is greater than the thickness dimension L2 of the flat structure. In this way, the width dimension L1 of the flat structure is larger, the metal part 202 has sufficient mechanical strength, and the thickness dimension L2 of the flat structure is smaller, so that the radial dimension of the reinforcement structure 200 is smaller and does not occupy too much space in the sub-cable 100. For example, the flat structure is rectangular.

[0078] Alternatively, if Figure 1 As shown, the surface of the cable 10 is provided with a skin layer 600 , which can have the functions of insulation and mechanical protection. The skin layer 600 can also reduce the risk of fatigue fracture of the sub-cable 100 .

[0079] like Fig.13 As shown, the charging data cable 1 described in the embodiment of the charging data cable of the present application includes a cable 10. Specifically, the charging data cable 1 includes a first connector 20, a second connector 30 and a cable 10. The cable 10 is connected between the first connector 20 and the second connector 30. The first connector 20 and the second connector 30 can be connected through the cable 10. For example, the cable 10 can be connected to a power source and a computer through the first connector 20. The cable 10 can be connected to devices such as mobile phones and headphones through the second connector 30.

[0080] Optionally, the first connector 20 is a USB interface, for example, the first connector 20 is a Standard type-A interface, a Mini type-A interface, a Micro type-A interface, a Standard type-B interface, a Mini type-B interface, a Microtype-B interface or a type-C interface.

[0081] Optionally, the second connector 30 is a micro USB interface, a type-C interface, or a lighting interface.

[0082] In summary, this embodiment can reduce the risk of fatigue fracture of the conductor part 110 and enhance the ability of the cable 10 to resist fatigue fracture. The fiber part 201 has a high tensile strength. When the cable 10 is pulled or bent, the fiber part 201 can share the tensile stress of the conductor part 110. The tensile stress of the conductor part 110 is small, thereby increasing the number of times the conductor part 110 can withstand the stretching and bending effects, making it difficult for the conductor part 110 to be broken. The metal part 202 has a large deformation margin, is easy to bend and deform, and is subject to small shear force when bending. When the cable 10 is bent, the metal part 202 can reduce the occurrence of stress concentration on the conductor part 110, reduce the probability of generating breakpoints on the conductor part 110, and make it difficult for the conductor part 110 to be broken due to bending.

[0083] The above descriptions are merely embodiments of the present application and are not intended to limit the patent scope of the present application.
