Description

[Technical Field]

[0001] The present application relates to the technical field of charging products, and in particular to cables and charging data cables. [Background technology]

[0002] With the development of science and technology, various electronic devices have appeared, which brings convenience to people's working life. Among them, electronic devices require cables to transmit electric current and electric signals, for example, the cable on a mobile phone data cable can be used for charging and data transmission of the mobile phone.

[0003] Currently, cables are often subjected to external forces such as pulling and bending during use, making them prone to fatigue fracture and unusable. Summary of the Invention [Problem to be solved by the invention]

[0004] The main technical problem that this application aims to solve is to provide a cable and a charging / data cable that can reduce the risk of fatigue fracture of the conductor portion inside the cable and improve the cable's resistance to fatigue fracture. [Means for solving the problem]

[0005] The first technical solution used by the present application to solve the above technical problems is to provide a cable. The cable includes a sub-cable having a conductive conductor portion and at least one reinforcing structure. Each reinforcing structure includes a fiber portion and at least one metal portion, the fiber portion extending along the extension direction of the sub-cable, and the at least one metal portion extending in a spiral shape along the extension direction of the fiber portion and surrounding the outer periphery of the fiber portion.

[0006] In order to solve the above technical problem, the second technical solution used by the present application is to provide a charging data cable including the cable according to the first technical solution.

[0007] The beneficial effects of the present application are as follows: Unlike the prior art, the cable includes sub-cables having conductive conductor portions and at least one reinforcing structure, each reinforcing structure including a fiber portion and at least one metal portion, the fiber portion extending along the extension direction of the sub-cable, and the at least one metal portion extending in a spiral shape along the extension direction of the fiber portion and surrounding the outer periphery of the fiber portion, thereby reducing the risk of fatigue fracture of the conductor portion and improving the fatigue fracture resistance of the cable. The fiber portion has high tensile strength and can share the tensile stress that the conductor portion experiences when the cable is pulled or bent. Because the tensile stress experienced by the conductor portion is small, the number of times the conductor portion can withstand pulling and bending can be increased, making the conductor portion less likely to tear off. The metal portion has a large deformation margin and is easily deformed by bending, but is subjected to small shear forces when bent. The provision of the metal portion reduces the concentration of stress on the conductor portion when the cable is bent, reducing the probability of breakage points occurring in the conductor portion and making the conductor portion less likely to break when bent.

[0009] Hereinafter, the technical means of the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, but it is obvious that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments, and all other embodiments that can be obtained by a person skilled in the art based on the embodiments of the present application without any creative work fall within the scope of protection of the present application.

[0010] Through long-term research, the inventor has discovered that electronic devices require cables for transmitting current and electrical signals, and that, for example, a cable like a data cable for a mobile phone can be used for charging and data transmission of the mobile phone. Currently, cables are often subjected to external forces such as pulling and bending during use, which makes them prone to fatigue fracture and unusable. To solve this technical problem, the present application provides the following embodiment.

[0011] 1 to 5, a cable 10 according to a cable embodiment of the present application includes a sub-cable 100 having a conductive conductor portion 110 and at least one reinforcing structure 200. Each reinforcing structure 200 includes a fiber portion 201 and at least one metal portion 202, the fiber portion 201 extending along the extension direction of the sub-cable 100, and the at least one metal portion 202 extending in a spiral shape along the extension direction of the fiber portion 201 and surrounding the outer periphery of the fiber portion 201.

[0012] During use, cable 10 is often subjected to external forces such as pulling and bending, which makes conductor 110 inside cable 10 prone to fatigue fracture and renders it unusable. By providing reinforcing structure 200, the risk of fatigue fracture of conductor 110 can be reduced and the fatigue fracture resistance of cable 10 can be improved.

[0013] Specifically, by providing fiber portion 201 with high tensile strength and extending along the extension direction of sub-cable 100, when cable 10 is pulled or bent, fiber portion 201 can share the tensile stress that conductor portion 110 receives, and because the tensile stress received by conductor portion 110 is small, the number of times that conductor portion 110 can withstand pulling and bending can be increased, making conductor portion 110 less likely to tear. By providing at least one metal portion 202 that extends in a spiral shape along the extension direction of fiber portion 201, metal portion 202 has a large deformation margin, is easily bent and deformed, receives only a small shear force when bent, and has low resistance to bending of cable 10, which is advantageous in that cable 10 maintains its flexibility and bendability. By providing the metal portion 202 when bending the cable 10, the concentration of stress on the conductor portion 110 is reduced, the probability of a breakage point occurring in the conductor portion 110 is reduced, and the conductor portion 110 is less likely to break when bent.

[0014] The metal part 202 spirally surrounds the outer periphery of the fiber part 201, which is advantageous for relatively fixing the metal part 202 and the position limiting part, and thereby the reinforcing structure 200 exists as an integrated structure, making it easier to introduce the reinforcing structure 200 into the inside of the cable 100 during the production process of the cable 10, improving production efficiency.

[0015] 3 and 4, the two metal parts 202 preferably extend spirally along the extension direction of the fiber part 201 and surround the outer periphery of the fiber part 201. The winding directions of the two metal parts 202 may be the same or opposite.

[0016] Preferably, the material of the metal part 202 is copper, aluminum, stainless steel, and other alloy materials.

[0017] Preferably, the fiber portion 201 includes at least one of nylon fiber, PET fiber, aramid fiber, and PE fiber.

[0018] Preferably, the conductor portion 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 electrical energy and electrical signals.

[0019] 1 and 6, the plurality of reinforcing structures 200 surround the outer periphery of at least one sub-cable 100 to form a protective layer 210. The plurality of reinforcing structures 200 are arranged in parallel so that the protective layer 210 forms a ring-shaped structure along a cross section in the axial direction perpendicular to the sub-cable 100.

[0020] By providing multiple reinforcing structures 200 to surround the outer periphery of at least one sub-cable 100, the multiple reinforcing structures 200 can protect the sub-cable 100 inside the protective layer 210 in multiple directions, and when the sub-cable 100 is pulled or bent in different directions, the protective layer 210 can protect the sub-cable 100 in all cases, thereby improving the protective effect of the protective layer 210 on the sub-cable 100 inside and reducing the risk of fatigue fracture of the conductor portion 110.

[0021] Furthermore, multiple reinforcing structures 200 can be arranged in contact with each other along the circumferential direction of the sub-cable 100, thereby improving the arrangement density of the reinforcing structures 200 and improving the protective effect on the sub-cable 100.

[0022] Preferably, the protective layer 210 may surround a single sub-cable 100, or may surround two or more sub-cables 100, and one protective layer 210 or at least two protective layers 210 may be provided within the cable 10. The different protective layers 210 may be provided independently of each other or may be nested within each other.

[0023] Preferably, each reinforcing structure 200 is wound around at least one sub-cable 100 along the extension direction of the sub-cables 100. Furthermore, each reinforcing structure 200 extends in a spiral shape along the extension direction of the sub-cables 100 and is wound around at least one sub-cable 100.

[0024] That is, the reinforcing structure 200 has a two-stage spiral structure in which the metal portion 202 spirally surrounds the outer periphery of the fiber portion 201 along the extension direction of the fiber portion 201, and then the metal portion 202 and the fiber portion 201 extend spirally along the extension direction of the sub-cable 100 and are wound around the sub-cable 100. This configuration achieves initial fixation of the reinforcing structure 200 to the sub-cable 100 after it is wound around the sub-cable 100, restricts the reinforcing structure 200 from falling off the sub-cable 100, and is advantageous for improving the stability of the production process of the cable 10.

[0025] 1 and 7, each of the sub-cables 100 is preferably located within a ring-shaped structure formed by the protective layer 210. That is, within the cable 10, there is a protective layer 210 that surrounds all of the sub-cables 100 of the cable 10. In this way, the protective layer 210 can protect all of the sub-cables 100 of the cable 10, which is advantageous in improving the overall protective effect of the cable 10.

[0026] For example, cable 10 may include six or seven sub-cables 100 all positioned within the annular structure formed by protective layer 210 .

[0027] Preferably, as shown in Figures 8 to 10, at least one of the sub-cables 100 is located within the annular structure formed by the protective layer 210, and at least one of the sub-cables 100 is located outside the protective layer 210. That is, within the cable 10, there is a protective layer 210 that surrounds some of the sub-cables 100 of the cable 10. In this way, the protective layer 210 can provide enhanced protection to the sub-cables 100 that are prone to breakage.

[0028] For example, as shown in FIG. 8, cable 10 may include seven sub-cables 100 and one protective layer 210, with four sub-cables 100 located within the annular structure formed by the protective layers 210 and three sub-cables 100 located outside the protective layers 210. Alternatively, as shown in FIG. 9, cable 10 may include six sub-cables 100 and two protective layers 210, with two sub-cables 100 located within each annular structure formed by the protective layers 210 and the remaining two sub-cables 100 located outside the two protective layers 210. Alternatively, as shown in FIG. 10, cable 10 may include seven sub-cables 100 and three protective layers 210, with three sub-cables 100 located within each annular structure formed by the three protective layers 210 and the remaining four sub-cables 100 located outside the protective layers 210.

[0029] In some embodiments, cable 10 may include at least two protective layers 210, with all sub-cables 100 and the remaining protective layers 210 disposed within an annular structure formed by one of the at least two protective layers 210, with at least one sub-cable 100 disposed within each of the remaining protective layers 210. For example, as shown in FIG. 7 , cable 10 may include seven sub-cables 100 and two protective layers 210, with one sub-cable 100 disposed within an annular structure formed by one of the protective layers 210, with all seven sub-cables 100 and one of the protective layers 210 located within an annular structure formed by another of the protective layers 210.

[0030] Preferably, as shown in Figures 1 and 6, the cable 10 further includes a sealing layer 300 surrounding the outer periphery of the protective layer 210. The provision of the sealing layer 300 allows the protective layer 210 to be stably fixed to the outer periphery of the sub-cable 100, which is advantageous in improving the stability of the production process. For example, the protective layer 210 may be a film-coated tape or a plastic injection-molded layer. Furthermore, the sealing layer 300 may have an insulating effect.

[0031] Furthermore, cable 10 may include at least two protective layers 210 and one sealing layer 300, with each sealing layer 300 surrounding the outer periphery of one of the protective layers 210. Alternatively, the sealing layers 300 and the protective layers 210 may be the same in number and in one-to-one correspondence, with each sealing layer 300 surrounding the outer periphery of the corresponding protective layer 210.

[0032] 1, the cable 10 preferably includes a shielding layer 400 that surrounds the outer periphery of at least one sub-cable 100. The shielding layer 400 surrounds the outer periphery of the protective layer 210.

[0033] The shielding layer 400 can reflect and absorb electromagnetic radiation and limit interference signals from entering the interior of the shielding layer 400, thereby reducing signal transmission loss of 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.

[0034] Preferably, shielding layer 400 is located within the annular structure formed by protective layer 210. In some embodiments, shielding layer 400 surrounds the outer periphery of a single sub-cable 100 to limit interference between the sub-cables 100. In some embodiments, shielding layer 400 surrounds the outer periphery of all sub-cables 100 to limit interference of external signals with the sub-cables 100.

[0035] Preferably, the cable 10 includes two or more shield layers 400 .

[0036] 9, the shield layer 400 preferably includes shielded cables 401 and reinforcing structures 200 arranged along the circumferential direction of the shield layer 400. In the shield layer 400, the ratio of the number of reinforcing structures 200 to the number of shielded cables 401 ranges from 5% to 10%.

[0037] The shielded cables 401 are made of a metal material or a plastic material with a metal coating. The shielded cables 401 may extend along the extension direction of the cable 10 or the sub-cable 100. By arranging the shielded cables 401 in close contact with each other along the circumferential direction of the shielding layer 400, the shielding effect against interference signals can be improved. Providing the reinforcing structure 200 within the shielding layer 400 is advantageous in improving the protection effect for the sub-cable 100.

[0038] Because the metal part 202 extends in a spiral shape, the reinforcing structure 200 itself has many gaps, and the shielding effect of the reinforcing structure 200 is weaker than that of the shielded cables 401, so the number of reinforcing structures 200 in the shielding layer 400 should not be too large, and the ratio of the number of reinforcing structures 200 to the number of shielded cables 401 should not exceed 10%. If the number of reinforcing structures 200 in the shielding layer 400 is too small, it will affect the protective effect, so the ratio of the number of reinforcing structures 200 to the number of shielded cables 401 should not be less than 5%.

[0039] For example, in the shielding layer 400, the ratio of the number of reinforcing structures 200 to the number of shielded cables 401 ranges from 2% to 5%.

[0040] Preferably, as shown in FIG. 8, the number of sub-cables 100 is at least two, and the reinforcing structure 200 is positioned in the gap between the sub-cables 100 and the shielding layer 400 as a first filling member 220, and the first filling member 220 is twisted together with the sub-cables 100.

[0041] The diameter of the sub-cables 100 may be larger than the diameter of the reinforcing structure 200. Different sub-cables 100 may be twisted together, with a gap between the twisted sub-cables 100 and the shielding layer 400. By providing the reinforcing structure 200 at the position of the gap and twisting it together with the sub-cables 100, the reinforcing structure 200 can protect the sub-cables 100. This arrangement is advantageous for improving the space utilization rate inside the cable 10.

[0042] Preferably, in the cable 10, the first filling member 220 and the sub-cable 100 may further be twisted with a filling material (e.g., fiber, soft cotton thread, etc.) to reduce the risk of fatigue fracture of the conductor portion 110.

[0043] Preferably, as shown in Figures 1 and 7, the number of sub-cables 100 is at least three, the reinforcing structure 200 is interspersed among the sub-cables 100 as second filling members 230, and the second filling members 230 are twisted together with the sub-cables 100.

[0044] The diameter of the sub-cables 100 may be larger than the diameter of the reinforcing structure 200. Different sub-cables 100 may be twisted together, with gaps between the twisted sub-cables 100. By providing the reinforcing structure 200 at the gap position and twisting the sub-cables 100 together, the reinforcing structure 200 can protect the sub-cables 100 and is advantageous in improving the space utilization rate inside the cable 10.

[0045] 1 and 7, at least three sub-cables 100 preferably extend helically along the extension direction of the cable 10 to form a helical cellular structure (not shown). The at least three sub-cables 100 are sequentially arranged along a cross section in the extension direction perpendicular to the cable 10 so that the cellular structure is annular along the cross section in the extension direction perpendicular to the cable 10. The reinforcing structures 200 are interspersed among the sub-cables 100 within the cellular structure.

[0046] Specifically, at least three sub-cables 100 are twisted together to extend in a spiral shape along the extension direction of the cable 10, forming a spiral cell structure. By providing at least three sub-cables 100 so that they are arranged in order along the extension direction perpendicular to the cable 10, sufficient deformation space can be provided between different sub-cables 100, making it easy to twist the different sub-cables 100 together.

[0047] Preferably, in the cable 10, the second filling member 230 and the sub-cable 100 may further be twisted with a filling material (e.g., fiber, soft cotton thread, etc.) to reduce the risk of fatigue fracture of the conductor portion 110.

[0048] 11 , the sub-cable 100 preferably further includes an insulating layer 120 surrounding the conductor portion 110. The conductor portion 110 includes a plurality of conductor wires 111. The reinforcing structure 200 is disposed between the plurality of conductor wires 111. The insulating layer 120 can prevent short-circuiting between different sub-cables 100. The insulating layer 120 can also protect the sub-cables 100 and reduce the risk of fatigue fracture of the sub-cables 100.

[0049] Conductor wire 111 is often subjected to external forces such as pulling and bending during use, making it prone to fatigue fracture and unusable. By providing reinforcing structure 200 inside sub-cable 100, the risk of fatigue fracture of conductor wire 111 can be reduced and the resistance of conductor wire 111 to fatigue fracture can be improved.

[0050] Specifically, the fiber portion 201 of the reinforcement structure 200 has a high tensile strength, and when the conductor wire 111 is pulled or bent, the fiber portion 201 can share the tensile stress that the conductor wire 111 receives, and because the tensile stress that the conductor wire 111 receives is small, the number of times that the conductor wire 111 can withstand pulling and bending can be increased, making the conductor wire 111 less likely to tear off. Also, the metal portion 202 of the reinforcement structure 200 has a large deformation margin, is easily deformed by bending, and receives only a small shear force when bending, which reduces the concentration of stress on the conductor wire 111 due to the metal portion 202 when the conductor wire 111 is bent, reduces the probability of a break point occurring in the conductor wire 111, and makes the conductor wire 111 less likely to break when bent.

[0051] Preferably, as shown in FIG. 12, the plurality of reinforcing structures 200 surround the outer periphery of the conductor portion 110 to form an inner protective layer 240 , and the insulating layer 120 surrounds the outer periphery of the inner protective layer 240 .

[0052] By providing multiple reinforcing structures 200 to surround the outer periphery of the conductor portion 110, the multiple reinforcing structures 200 can protect the conductor portion 110 inside the inner protective layer 240 in multiple directions, and when the conductor portion 110 is pulled or bent in different directions, the inner protective layer 240 can protect the conductor portion 110 in all cases, thereby improving the protective effect on the conductor portion 110 and reducing the risk of fatigue fracture of the conductor portion 110.

[0053] Furthermore, multiple reinforcing structures 200 can be arranged in contact with each other along the circumferential direction of the conductor portion 110, thereby improving the arrangement density of the reinforcing structures 200 and improving the protective effect on the conductor portion 110.

[0054] Preferably, the number of sub-cables 100 is plural, and an insulating layer 120 is provided on the outer periphery of the conductor portion 110 of at least one sub-cable 100, and an insulating layer 120 is not provided on the outer periphery of the conductor portion 110 of at least the other sub-cables 100.

[0055] In other embodiments, the conductor portion 110 is a single copper wire or a copper wire with a single plating layer, such as a tin-plated copper wire, a silver-plated copper wire, or the like.

[0056] Preferably, the conductor wire 111 is a thin copper wire or a thin copper wire having a plating layer, such as a tin-plated copper wire or a silver-plated copper wire.

[0057] Preferably, in the sub-cable 100, the ratio of the number of reinforcing structures 200 to the number of conductor wires 111 is 1% to 10%.

[0058] Because the metal portion 202 extends in a spiral shape, has a large degree of curvature, and has a weaker ability to transmit current or electrical signals than the conductor wires 111, the number of reinforcing structures 200 added to the sub-cable 100 should not be too large, and the ratio of the number of reinforcing structures 200 to the number of conductor wires 111 should not exceed 10%. If the number of reinforcing structures 200 in the sub-cable 100 is too small, it will affect the protective effect, so the ratio of the number of reinforcing structures 200 to the number of conductor wires 111 should not be less than 1%.

[0059] For example, in the sub-cable 100, the ratio of the number of reinforcing structures 200 to the number of conductor wires 111 is 2% or 5%.

[0060] Preferably, in the sub-cable 100, the reinforcing structure 200 and the conductor wires 111 may further be twisted with a filler material (such as nylon fibers) to reduce the risk of fatigue fracture of the conductor portion 110.

[0061] Preferably, as shown in FIG. 4, the cross section of the metal part 202 in the extending direction perpendicular to the metal part 202 has a circular structure, and the diameter dimension D1 of the circular structure is in the range of 0.03 mm to 0.20 mm.

[0062] Furthermore, the diameter D1 of the circular structure ranges from 0.05 mm to 0.15 mm. For example, the diameter D1 of the circular structure ranges from 0.06 mm to 0.10 mm.

[0063] By providing the metal portion 202 in this manner, the metal portion 202 has sufficient mechanical strength, and the radial dimension of the reinforcing structure 200 is small, so that it does not occupy much space within the sub-cable 100 .

[0064] 2, the cross section of the metal part 202 preferably has a flat structure in the extension direction perpendicular to the metal part 202, with the width dimension L1 of the flat structure ranging from 0.1 mm to 1.0 mm and the thickness dimension L2 of the flat structure ranging from 0.01 mm to 0.1 mm. For example, the width dimension L1 of the flat structure is 0.2 mm or 0.6 mm, and the thickness dimension L2 of the flat structure is 0.02 mm, 0.05 mm, or 0.07 mm. Furthermore, the thickness direction D2 of the flat structure is perpendicular to the extension direction of the fiber part 201.

[0065] The width dimension L1 of the flat structure is larger than the thickness dimension L2 of the flat structure, and by configuring it in this manner, the width dimension L1 of the flat structure can be increased, providing sufficient mechanical strength to the metal part 202, and by reducing the thickness dimension L2 of the flat structure, the radial dimension of the reinforcing structure 200 can be reduced, and it does not occupy much space within the sub-cable 100. The flat structure is, for example, rectangular.

[0066] 1, the surface of the cable 10 is preferably provided with a skin layer 600 that can provide insulation and mechanical protection. The skin layer 600 can also reduce the risk of fatigue fracture of the sub-cable 100.

[0067] As shown in FIG. 13 , the charging data cable 1 described in the charging data cable embodiment of the present application includes a cable 10. Specifically, the charging data cable 1 includes a first connector 20, a second connector 30, and the 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 may be connected via the cable 10. For example, the cable 10 may be connected to a power source and a computer via the first connector 20. The cable 10 is connected to a device such as a mobile phone, earphones, etc. via the second connector 30.

[0068] Preferably, the first connector 20 is a USB interface, such as 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 Micro Type-B interface, or a Type-C interface.

[0069] Preferably, the second connector 30 is a micro USB interface, a Type-C interface, or a lighting interface.

[0070] As described above, this embodiment can reduce the risk of fatigue fracture of the conductor portion 110 and improve the fatigue fracture resistance of the cable 10. The fiber portion 201 has high tensile strength, and when the cable 10 is pulled or bent, the fiber portion 201 can share the tensile stress that the conductor portion 110 experiences. Because the tensile stress experienced by the conductor portion 110 is small, the number of times the conductor portion 110 can withstand pulling and bending can be increased, making the conductor portion 110 less likely to tear off. The metal portion 202 has a large deformation margin, is easily deformed by bending, and experiences little shear force when bending. The provision of the metal portion 202 reduces the concentration of stress on the conductor portion 110 when the cable 10 is bent, reducing the probability of a fracture occurring in the conductor portion 110 and making the conductor portion 110 less likely to break when bent.

[0071] The above are merely examples of the present application and do not limit the scope of the patent of the present application. Any equivalent structure or equivalent flow transformation created using the contents of the specification and drawings of the present application, or any direct or indirect operation in other related technical fields, are all similarly included in the scope of patent protection of the present application.
