[0027] To more clearly illustrate the technical solutions in the embodiments of the present application or related technologies, the following will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0028] Data cables are generally relatively long, and it is easy for them to get tangled up when carried. This not only makes it inconvenient for users to untangle the data cables, but also affects the access to other items. In related technologies, users will use some storage bags or storage boxes to store data cables, but this storage method will increase the overall weight and volume, and it is also not convenient for users to carry around.

[0029] In view of the above situation, please refer to Figures 1 - 3 , the present application proposes a data cable 1, which includes an electromagnetic shielding shell 10, a wire core assembly 20, and a magnetic adhesive layer 30.

[0030] The wire core assembly 20 is located inside the electromagnetic shielding shell 10. The electromagnetic shielding shell 10 can ensure the stability of the signals transmitted in the wire core assembly 20 and reduce external electromagnetic interference. Among them, the wire 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 wire core assembly 20, etc.; the electromagnetic shielding shell 10 can be prepared from metal materials or metal and plastic composite materials. Metal materials such as copper wire braided nets, copper wire winding layers, etc. Metal and plastic composite materials can be prepared by compounding plastic films and conductive materials, such as composites of PET and aluminum foil, composites of PET and graphene, etc.

[0031] The magnetic adhesive layer 30 is disposed around the outer periphery of the electromagnetic shielding shell 10 and is connected to the electromagnetic shielding shell 10. Specifically, the magnetic adhesive layer 30 can be prepared from a composite material of magnetic powder and plastic. For example, the ratio of magnetic powder to plastic is between 5% and 85%, so that the magnetic adhesive layer 30 has the insulating physical properties of ordinary plastic, can protect the internal electromagnetic shielding shell 10 and the wire core assembly 20, reduce the external wear on 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 while the magnetic adhesive layer 30 has magnetism, it can still ensure the insulation of the magnetic adhesive layer 30. When the data cable 1 is coiled and stored, the wire body part of the data cable 1 can approach each other under the action of the magnetic adsorption force of the magnetic adhesive layer 30, so that the process of coiling and storing the data cable can be completed more easily. Specifically, the coiling and storing of the data cable 1 means that the data cable is stacked in a spiral layer by layer (as Figure 1 shown).

[0032] Among them, as Figure 1 shown, the data line 1 further includes a first connector 51 and a second connector 52. The first connector 51 and the second connector 52 are respectively electrically connected to opposite ends of the wire core assembly 20. The first connector 51 is used to be electrically connected to a power source, and the second connector 52 is used to be electrically connected to an electronic device. The data line 1 can charge the electronic device or transmit data through the first connector 51, the second connector 52, and the wire core assembly 20.

[0033] It should be noted that in the embodiment of the present application, by providing a magnetic glue layer 30 having both plastic properties and magnetism on the outer periphery of the electromagnetic shielding case 10, when the data line 1 is coiled and stored, the wire bodies of the adjacent layers of the data line 1 can be adsorbed to each other under the action of magnetic attraction (as Figure 1 and Figure 3 shown), reducing the probability of the data line 1 being entangled during storage, which is beneficial to the storage of the data line 1 and thus convenient for the user to carry. At the same time, the plastic properties of the magnetic glue layer 30 can ensure the elasticity and cushioning and shock-absorbing effects of the magnetic glue layer 30, reducing the possibility of the magnetic glue layer 30 being broken or torn when the data line 1 is coiled and stored.

[0034] It should also be noted that in this embodiment, there is no need to additionally provide a magnet or a coil spring, and the coiling and storage of the data line 1 can be realized through magnetic adsorption, thereby reducing the volume change of the data line 1. Among them, in the embodiment of the present application, the cross-sectional size of the data line 1 and the thickness of the magnetic glue layer 30 are not specifically limited. For example, the cross-section of the data line 1 is circular, and the diameter range of the cross-section of the data line 1 is 3.0 mm to 6.0 mm, and the thickness range of the magnetic glue layer 30 is 0.3 mm to 2.0 mm, etc.

[0035] As Figure 2 shown, in some embodiments of the present application, the data line 1 further includes a filling material 40. The filling material 40 extends along the length direction of the wire core assembly 20. The filling material 40 is located inside the electromagnetic shielding case 10, and the filling material 40 is stranded and connected to the wire core assembly 20.

[0036] Specifically, the stranding connection means that a plurality of filling materials 40 with the same diameter or different diameters and the wire core assembly 20 are stranded together around a stranding shaft in a certain rotation direction, so that the filling material 40 and the wire core assembly 20 become an integral body. The filling material 40 can be used to enhance the internal structure of the data line 1. The filling material 40 and the wire core assembly 20 are arranged and stranded together, thereby improving the strength of the wire core assembly 20. Among them, the filling material 40 can be plastic fiber (nylon fiber, bulletproof silk fiber, polyethylene fiber, etc.) or cotton thread, etc.

[0037] Please refer to Figures 3 - 4, in some embodiments of the present application, the outer peripheral side of the magnetic glue layer 30 includes a first plane 31 and a second plane 32. The first plane 31 and the second plane 32 are oppositely arranged and extend along the length direction of the data line 1.

[0038] It can be understood that, as Figure 1 shown, when the data line 1 is stored in a coiled manner, the data line 1 is stored in a coiled disk shape. As Figure 3 shown, the data lines 1 in adjacent layers are stacked by magnetic attraction. At this time, the first plane 31 of the first-layer data line 1 contacts the second plane 32 of the second-layer data line 1. The setting of the plane can make the data line 1 more stable when stored in a coiled manner. In some other embodiments, the outer periphery of the magnetic glue layer 30 can also be set as an arc surface to make the user feel better when holding the data line 1.

[0039] Among them, the first plane 31 and the second plane 32 can be arranged at an angle or parallel. Here, it can be selected according to specific circumstances. In some embodiments, the first plane 31 and the second plane 32 are parallel, so that the data line 1 can be stacked more easily when stored in a coiled manner. Exemplarily, as Figure 5 shown, the cross-section of the magnetic glue layer 30 is square, so as to increase the plane where the data line 1 is likely to be stacked, so that the data line 1 can be stored in a coiled manner from more angles.

[0040] Please refer to Figures 6 - 7 , in some embodiments of the present application, multiple layers of magnetic glue layers 30 are provided. The multiple layers of magnetic glue layers 30 are arranged in sequence away from the electromagnetic shielding case 10. The magnetic powder content in each magnetic glue layer 30 is different, so the magnetic force of each magnetic glue layer 30 is also different. Among them, the magnetic powder content in each magnetic glue layer 30 can be set arbitrarily, and the relationship between the magnetic powder contents of each magnetic glue layer in this embodiment can be not limited at all. For example, three layers of magnetic glue layers 30 are provided, and the three layers of magnetic glue layers 30 are the first magnetic glue layer 33, the second magnetic glue layer 34, and the third magnetic glue layer 35 from the innermost layer to the outermost layer. The magnetic powder content in the first magnetic glue layer 33 is 20%, the magnetic powder content in the second magnetic glue layer 34 is 70%, and the magnetic powder content in the third magnetic glue layer 35 is 25%.

[0041] Or, in some other embodiments, the magnetic powder content in each magnetic glue layer 30 is the same, so the magnetic force of each magnetic glue layer 30 is also the same. For example, the magnetic powder content in the first magnetic glue layer 33, the second magnetic glue layer 34, and the third magnetic glue layer 35 is all 45%.

[0042] In some embodiments of the present application, the magnetic force of the magnetic glue layer 30 is inversely proportional to the distance between the magnetic glue layer 30 and the electromagnetic shielding case 10.

[0043] Specifically, the magnetic force of the magnetic adhesive layer 30 refers to the magnetic adsorption force possessed by the magnetic adhesive layer 30. The wire body parts of the data lines 1 can approach each other under the action of this magnetic adsorption force. The innermost layer of the multiple magnetic adhesive layers 30 refers to the layer closest to the electromagnetic shielding shell 10, and the outermost layer refers to 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 sequentially from the innermost layer to the outermost layer, and the magnetic force of the magnetic adhesive layer 30 closer to the electromagnetic shielding shell 10 is greater.

[0044] It should be noted that the ratio of magnetic powder to plastic in the magnetic adhesive layer 30 is between 5% and 85%. The greater the proportion of magnetic powder contained in the magnetic adhesive layer 30, the greater the magnetic force of the magnetic adhesive layer 30, but the lower the reliability of the magnetic adhesive layer 30. That is to say, the magnetic adhesive layer 30 with a larger magnetic powder ratio is prone to breakage. Therefore, the content of magnetic powder in the outermost magnetic adhesive layer 30 is the lowest and the magnetic force is the smallest, which makes the reliability of the outermost magnetic adhesive layer 30 better and reduces the probability of breakage of the outermost magnetic adhesive layer 30; the content of magnetic powder in the innermost magnetic adhesive layer 30 is the highest and the magnetic force is the largest, which enables the magnetic adhesive layer 30 to have sufficient magnetic force to ensure the coiling and storage of the data lines 1. Exemplarily, the magnitudes of the magnetic forces of the three magnetic adhesive layers 30 are in sequence: 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 content of magnetic powder in the first magnetic adhesive layer 33 is 85%, the content of magnetic powder in the second magnetic adhesive layer 34 is 45%, and the content of magnetic powder in the third magnetic adhesive layer 35 is 5%.

[0045] Alternatively, in some other 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 to say, 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 closer to the electromagnetic shielding shell 10 is smaller. Exemplarily, the magnitudes of the magnetic forces of the three magnetic adhesive layers 30 are in sequence: 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 content of magnetic powder in the first magnetic adhesive layer 33 is 5%, the content of magnetic powder in the second magnetic adhesive layer 34 is 45%, and the content of magnetic powder in the third magnetic adhesive layer 35 is 85%.

[0046] Furthermore, please continue to refer to Figures 6 - 7 , in some embodiments of the present application, the thickness of the magnetic adhesive layer 30 is inversely proportional to the distance between the magnetic adhesive layer 30 and the electromagnetic shielding shell 10.

[0047] Specifically, the greater the distance between the magnetic glue layer 30 and the electromagnetic shielding shell 10, the smaller the thickness of the magnetic glue layer 30. That is to say, the thickness of the magnetic glue layer 30 decreases successively from the innermost layer to the outermost layer. The closer the magnetic glue layer 30 is to the electromagnetic shielding shell 10, the greater its thickness, thereby reducing the magnetic force obstruction of the magnetic glue layer 30 in the outer layer to the magnetic glue layer 30 in the inner layer. It can be understood that when the magnetic force of the magnetic glue layer 30 is inversely proportional to the distance between the magnetic glue layer 30 and the electromagnetic shielding shell 10, the outermost magnetic glue layer 30 has a smaller magnetic force, so its thickness is also set smaller, thereby reducing the obstruction to the magnetic force of other magnetic glue layers 30 in the inner layer.

[0048] As Figure 7 shown, the thicknesses of the first magnetic glue layer 33, the second magnetic glue layer 34, and the third magnetic glue layer 35 are H1, H2, and H3 respectively. The thicknesses of the three magnetic glue layers 30 are in the order of: H1 > H2 > H3. For example, the thickness of the first magnetic glue layer 33 is 2 mm, the thickness of the second magnetic glue layer 34 is 0.8 mm, and the thickness of the third magnetic glue layer 35 is 0.3 mm.

[0049] Please refer to Figure 8 , in some embodiments of the present application, the wire core assembly 20 includes multiple wire cores 22. The magnetic glue layer 30 is in a flat tubular shape, and the multiple wire cores 22 are arranged in sequence along the length direction of the cross-section of the magnetic glue layer 30. It can be understood that by designing the overall shape of the magnetic glue layer 30 into a flat tubular shape, the electromagnetic shielding shell 10 can also be in a flat tubular shape. On the basis that the electromagnetic shielding shell 10 has enough space to accommodate the wire cores 22, the overall thicknesses of the magnetic glue layer 30 and the electromagnetic shielding shell 10 can be designed to be relatively thin, so that the thickness of the data cable 1 can also be designed to be relatively thin, thereby making it easier for the data cable 1 to be coiled and stored, and having stronger bendability, making the coiling and storage of the data cable 1 more convenient.

[0050] Or, please refer to Figures 9 - 10 , in some embodiments of the present 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 glue layer 30 is in a flat tubular shape, and multiple wire core groups 21 are arranged in sequence along the length direction of the cross-section of the magnetic glue layer 30.

[0051] Specifically, as Figure 9 shown, taking the wire core assembly 20 including 2 wire core groups 21 as an example, the first wire core group 211 in the 2 wire core groups 21 includes one wire core 22, and this wire core 22 is used for controlling signal transmission. The second wire core group 212 in the 2 wire core groups 21 includes four wire cores 22. The four wire cores 22 can be a charging positive wire core 22, a charging negative wire core, a data transmission D+ wire core, and a 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 Figure 10As shown, taking the core assembly 20 including 3 core groups 21 as an example, the first core group 211 among the 3 core groups 21 includes one core 22, and this core 22 is used for control signal transmission. The second core group 212 among the 3 core groups 21 includes two cores 22, and the two cores 22 can be a charging positive core 22 and a charging negative core wire respectively. The third core group 213 among the 3 core groups 21 includes two cores 22, and the two cores 22 can be a data transmission D+ core wire and a data transmission D- core wire respectively. The first core group 211, the second core group 212 and the third core group 213 are arranged along the length direction of the cross-section of the electromagnetic shielding shell 10.

[0052] Further, the first core group 211 among the multiple core groups 21 includes multiple cores 22, and the multiple cores 22 in the first core group 211 are stranded and connected. Among them, as Figure 10 shown, the core 22 includes a conductor 221 and an insulating layer 222. The insulating layer 222 is arranged around the outer periphery of the conductor 221 and is connected to the conductor 221.

[0053] In the drawings of this embodiment, the same or similar reference numerals correspond to the same or similar components; in the description of the present application, it should be understood that if there are terms such as "upper", "lower", "left", "right", etc. indicating the orientation or positional relationship, it is based on the orientation or positional relationship shown in the drawings.
