[0025] To more clearly illustrate the technical solutions in the embodiments of this application or related technologies, a clear and complete description will be provided below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0026] Data cables are generally quite long, and they easily get tangled when carried, making it inconvenient for users to untangle them and also affecting access to other items. While some users use storage bags or boxes to store data cables, this method increases the overall weight and size, making it even less convenient for users to carry around.

[0027] In view of the above situation, please refer to Figures 1-3. This application proposes a data cable 1, including an electromagnetic shielding shell 10, a wire core assembly 20 and a magnetic adhesive layer 30.

[0028] The core assembly 20 is located inside the electromagnetic shielding shell 10. The electromagnetic shielding shell 10 can ensure the stability of the signal transmitted in the core assembly 20 and reduce external electromagnetic interference. The core assembly 20 is used to transmit current or signals. That is, the data cable 1 can charge electronic devices or transmit data through the core assembly 20. The electromagnetic shielding shell 10 can be made of metal materials or metal and plastic composite materials. Metal materials include copper wire braided mesh, copper wire winding layer, etc. Metal and plastic composite materials can be made of plastic film and conductive materials, such as PET and aluminum foil composite materials, PET and graphene composite materials, etc.

[0029] The magnetic adhesive layer 30 is arranged around the outer periphery of the electromagnetic shielding shell 10 and connected to the electromagnetic shielding shell 10. Specifically, the magnetic adhesive layer 30 can be made of a composite material of magnetic powder and plastic, such as the ratio of magnetic powder to plastic being between 5% and 85%, so that the magnetic adhesive layer 30 has the insulating physical properties of general plastic, which can protect the internal electromagnetic shielding shell 10 and the wire core assembly 20, reduce the external wear of the electromagnetic shielding shell 10 and the wire core assembly 20, and provide insulation protection for the wire core assembly 20. At the same time, the magnetic powder can be some magnetic metal oxides (such as iron oxide Fe2O3, nickel oxide NiO, etc.), so that the magnetic adhesive layer 30 also has magnetism, and the magnetic adhesive layer 30 can still maintain its insulation while having magnetism. When the data cable 1 is coiled, the wire part of the data cable 1 can come closer to each other under the magnetic attraction force of the magnetic adhesive layer 30, so that the coiling process can be completed more easily. Specifically, the coiled cable storage of data cable 1 refers to the data cable being stacked together in a spiral shape, layer by layer (as shown in Figure 1).

[0030] As shown in Figure 1, the data cable 1 also includes a first connector 51 and a second connector 52. The first connector 51 and the second connector 52 are electrically connected to the opposite ends of the wire core assembly 20, respectively. The first connector 51 is used to be electrically connected to the power supply, and the second connector 52 is used to be electrically connected to the electronic device. The data cable 1 can charge the electronic device or transmit data through the first connector 51, the second connector 52 and the wire core assembly 20.

[0031] It should be noted that, in this embodiment, a magnetic adhesive layer 30 with both plastic and magnetic properties is provided on the outer periphery of the electromagnetic shielding shell 10. This allows the adjacent layers of the data cable 1 to attract each other under magnetic attraction when the data cable 1 is coiled up (as shown in Figures 1 and 3), reducing the probability of the data cable 1 becoming tangled during storage and facilitating its storage, thus making it easier for users to carry. Simultaneously, the plastic properties of the magnetic adhesive layer 30 ensure its elasticity and cushioning effect, reducing the possibility of breakage or tearing of the magnetic adhesive layer 30 when the data cable 1 is coiled up.

[0032] It should also be noted that in this embodiment, no additional magnets or coil springs are required; magnetic adsorption is sufficient to coil and store the data cable 1, thereby reducing the change in the volume of the data cable 1. Furthermore, this embodiment does not impose specific limitations on the cross-sectional dimensions of the data cable 1 or the thickness of the magnetic adhesive layer 30. For example, the cross-section of the data cable 1 can be circular, with a diameter ranging from 3.0 mm to 6.0 mm, and the thickness of the magnetic adhesive layer 30 can range from 0.3 mm to 2.0 mm.

[0033] As shown in Figure 2, in some embodiments of this application, the data line 1 further includes a filler material 40, which extends along the length of the core assembly 20, is located inside the electromagnetic shielding shell 10, and is twisted together with the core assembly 20.

[0034] Specifically, twisting connection refers to twisting multiple filler materials 40 of the same or different diameters and wire core assembly 20 together around a twisting shaft in a certain rotation direction, making the filler material 40 and wire core assembly 20 a whole. The filler material 40 can be used to enhance the internal structure of the data cable 1. The filler material 40 and wire core assembly 20 are arranged and twisted together, thereby improving the strength of the wire core assembly 20. The filler material 40 can be plastic fiber (nylon fiber, bulletproof fiber, polyethylene fiber, etc.) or cotton thread, etc.

[0035] Please refer to Figures 3-4. In some embodiments of this application, the outer peripheral side of the magnetic adhesive layer 30 includes a first plane 31 and a second plane 32. The first plane 31 and the second plane 32 are disposed opposite to each other and extend along the length direction of the data line 1.

[0036] As can be understood, as shown in Figure 1, when the data cable 1 is coiled, it is coiled up. As shown in Figure 3, adjacent layers of data cables 1 are stacked by magnetic attraction. At this time, the first plane 31 of the first layer of data cables 1 is in contact with the second plane 32 of the second layer of data cables 1. The planar design makes the data cable 1 more stable when coiled. In some other embodiments, the outer periphery of the magnetic adhesive layer 30 can also be set as an arc surface to improve the user's feel when holding the data cable 1.

[0037] The first plane 31 and the second plane 32 can be arranged at an angle or parallel to each other, depending on the specific situation. In some embodiments, the first plane 31 and the second plane 32 are arranged parallel, which makes it easier to stack the data cable 1 when coiling it up. For example, as shown in FIG5, the cross-section of the magnetic adhesive layer 30 is square, thereby increasing the plane on which the data cable 1 can be easily stacked, thus allowing the data cable 1 to be coiled up from more angles.

[0038] Please refer to Figures 6 and 7. In some embodiments of this application, the magnetic adhesive layer 30 is provided in multiple layers, arranged sequentially away from the electromagnetic shielding shell 10. The magnetic powder content in each magnetic adhesive layer 30 is different, so the magnetic force of each magnetic adhesive layer 30 is also different. The magnetic powder content in each magnetic adhesive layer 30 can be arbitrarily set. In this embodiment, the relationship between the magnetic powder contents of each magnetic adhesive layer is not limited. For example, the magnetic adhesive layer 30 is provided in three layers, which are, from the innermost to the outermost, a first magnetic adhesive layer 33, a second magnetic adhesive layer 34, and a third magnetic adhesive layer 35. The magnetic powder content in the first magnetic adhesive layer 33 is 20%, the magnetic powder content in the second magnetic adhesive layer 34 is 70%, and the magnetic powder content in the third magnetic adhesive layer 35 is 25%.

[0039] Alternatively, in some embodiments, the magnetic powder content in each magnetic adhesive layer 30 is the same, so the magnetic force of each magnetic adhesive layer 30 is also the same. For example, the magnetic powder content in the first magnetic adhesive layer 33, the second magnetic adhesive layer 34, and the third magnetic adhesive layer 35 is all 45%.

[0040] In some embodiments of this application, the magnetic force of the magnetic adhesive layer 30 is inversely proportional to the distance between the magnetic adhesive layer 30 and the electromagnetic shielding shell 10.

[0041] Specifically, the magnetic force of the magnetic adhesive layer 30 refers to the magnetic attraction force of the magnetic adhesive layer 30. The wire parts of the data cable 1 can approach each other under the action of this magnetic attraction force. The innermost layer of the multi-layer magnetic adhesive layer 30 is the layer closest to the electromagnetic shielding shell 10, and the outermost layer is the layer farthest from the electromagnetic shielding shell 10. The greater the distance between the magnetic adhesive layer 30 and the electromagnetic shielding shell 10, the smaller the magnetic force of the magnetic adhesive layer 30. That is to say, the magnitude of the magnetic force generated by the magnetic adhesive layer 30 decreases from the innermost layer to the outermost layer, and the magnetic force of the magnetic adhesive layer 30 is greater the closer it is to the electromagnetic shielding shell 10.

[0042] It should be noted that the ratio of magnetic powder to plastic in the magnetic adhesive layer 30 is between 5% and 85%. The higher the proportion of magnetic powder in the magnetic adhesive layer 30, the stronger the magnetic force of the magnetic adhesive layer 30, but the lower the reliability of the magnetic adhesive layer 30. In other words, the magnetic adhesive layer 30 with a higher proportion of magnetic powder is more prone to damage. Therefore, the outermost magnetic adhesive layer 30 has the lowest content of magnetic powder and the weakest magnetic force, which makes the outermost magnetic adhesive layer 30 more reliable and reduces the probability of damage to the outermost magnetic adhesive layer 30. The innermost magnetic adhesive layer 30 has the highest content of magnetic powder and the strongest magnetic force, which makes the magnetic adhesive layer 30 have sufficient magnetic force to ensure the coiled storage of the data cable 1. For example, the magnetic forces of the three magnetic adhesive layers 30 are as follows: the magnetic force of the first magnetic adhesive layer 33 > the magnetic force of the second magnetic adhesive layer 34 > the magnetic force of the third magnetic adhesive layer 35, and the magnetic powder content in the first magnetic adhesive layer 33 is 85%, the magnetic powder content in the second magnetic adhesive layer 34 is 45%, and the magnetic powder content in the third magnetic adhesive layer 35 is 5%.

[0043] Alternatively, in some embodiments, the magnetic force of the magnetic adhesive layer 30 is proportional to the distance between the magnetic adhesive layer 30 and the electromagnetic shielding shell 10. That is, the magnitude of the magnetic force generated by the magnetic adhesive layer 30 increases sequentially from the innermost layer to the outermost layer, and the magnetic force of the magnetic adhesive layer 30 decreases as it gets closer to the electromagnetic shielding shell 10. For example, the magnetic forces of the three magnetic adhesive layers 30 are as follows: the magnetic force of the third magnetic adhesive layer 35 > the magnetic force of the first magnetic adhesive layer 33 > the magnetic force of the second magnetic adhesive layer 34, and the magnetic powder content in the first magnetic adhesive layer 33 is 5%, the magnetic powder content in the second magnetic adhesive layer 34 is 45%, and the magnetic powder content in the third magnetic adhesive layer 35 is 85%.

[0044] Furthermore, please continue to refer to Figures 6-7. In some embodiments of this application, the thickness of the magnetic adhesive layer 30 is inversely proportional to the distance from the magnetic adhesive layer 30 to the electromagnetic shielding shell 10.

[0045] Specifically, the greater the distance between the magnetic adhesive layer 30 and the electromagnetic shielding shell 10, the smaller the thickness of the magnetic adhesive layer 30. In other words, the thickness of the magnetic adhesive layer 30 decreases sequentially from the innermost layer to the outermost layer, with the outermost layer being thicker than the innermost layer. This reduces the magnetic resistance of the outermost magnetic adhesive layer 30 to the innermost layer. It can be understood that when the magnetic force of the magnetic adhesive layer 30 is inversely proportional to the distance between it and the electromagnetic shielding shell 10, the outermost layer has a smaller magnetic force, so its thickness is also smaller, thus reducing the magnetic resistance to the other inner layers.

[0046] As shown in Figure 7, the thicknesses of the first magnetic adhesive layer 33, the second magnetic adhesive layer 34, and the third magnetic adhesive layer 35 are H1, H2, and H3, respectively. The thicknesses of the three magnetic adhesive layers 30 are in the order of H1 > H2 > H3. For example, the thickness of the first magnetic adhesive layer 33 is 2 mm, the thickness of the second magnetic adhesive layer 34 is 0.8 mm, and the thickness of the third magnetic adhesive layer 35 is 0.3 mm.

[0047] Please refer to Figure 8. In some embodiments of this application, the wire core assembly 20 includes multiple wire cores 22, and the magnetic adhesive layer 30 is in the shape of a flat tube. The multiple wire cores 22 are arranged sequentially along the length direction of the cross-section of the magnetic adhesive layer 30. It can be understood that by designing the overall shape of the magnetic adhesive layer 30 as a flat tube, the electromagnetic shielding shell 10 can also be in the shape of a flat tube. On the basis that the electromagnetic shielding shell 10 has enough space to accommodate the wire cores 22, the overall thickness of the magnetic adhesive layer 30 and the electromagnetic shielding shell 10 can be designed to be thinner, so that the thickness of the data cable 1 can also be designed to be thinner. This makes it easier to coil and store the data cable 1, and the bending performance is stronger, making it more convenient to coil and store the data cable 1.

[0048] Alternatively, please refer to Figures 9-10. In some embodiments of this application, the wire core assembly 20 includes multiple wire core groups 21, each wire core group 21 includes at least one wire core 22, the magnetic adhesive layer 30 is in the shape of a flat tube, and the multiple wire core groups 21 are arranged sequentially along the length direction of the cross-section of the magnetic adhesive layer 30.

[0049] Specifically, as shown in Figure 9, taking the wire core assembly 20, which includes two wire core groups 21, as an example, the first wire core group 211 of the two wire core groups 21 includes one wire core 22, which is used for control signal transmission. The second wire core group 212 of the two wire core groups 21 includes four wire cores 22, which can be the charging positive electrode wire core 22, the charging negative electrode wire core, the data transmission D+ wire core, and the data transmission D- wire core, respectively. The first wire core group 211 and the second wire core group 212 are arranged along the length direction of the cross-section of the electromagnetic shielding shell 10. As shown in Figure 10, taking the wire core assembly 20, which includes three wire core groups 21, as an example, the first wire core group 211 of the three wire core groups 21 includes one wire core 22, which is used for control signal transmission. The second wire core group 212 of the three wire core groups 21 includes two wire cores 22, which can be the charging positive electrode wire core 22 and the charging negative electrode wire, respectively. The third wire core group 213 of the three wire core groups 21 includes two wire cores 22, which can be the data transmission D+ wire and the data transmission D- wire, respectively. The first wire core group 211, the second wire core group 212 and the third wire core group 213 are arranged along the length direction of the cross-section of the electromagnetic shielding shell 10.

[0050] Furthermore, the first core group 211 of the plurality of core groups 21 includes a plurality of cores 22, and the plurality of cores 22 in the first core group 211 are twisted together. As shown in FIG10, the core 22 includes a conductor 221 and an insulation layer 222, the insulation layer 222 being disposed around the outer periphery of the conductor 221 and connected to the conductor 221.
