Description

A magnetic absorption nano data cable Technical Field

[0001] This application relates to the field of data cable technology, specifically to a magnetically absorbed nano data cable. Background Technology

[0002] The purpose of data cables is to meet the dual needs of data transmission and charging between electronic devices. Through an internal conductive cable and an external connector, they can connect devices to power sources or other devices, thereby achieving efficient data transmission and a stable power supply. However, data cables are usually designed to be quite long, such as 1.5 meters, to facilitate connection and use by users, which to some extent makes data cable storage inconvenient.

[0003] Most data cables sold on the market are stored and organized by manually winding and freely placing them. Data cables are not easy to store, and they become messy after being coiled. They are also bulky and inconvenient to use.

[0004] Utility Model Content

[0005] The application provides a magnetically absorbable data cable that can be naturally magnetically attracted when folded, which can shorten the length of the data cable during use and reduce the size of the data cable when stored, making it convenient to use and carry.

[0006] This application provides a magnetically absorbent data cable, which includes a cable body and connecting plugs located at both ends of the cable body;

[0007] The line includes a first segment, a dividing segment, and a second segment connected sequentially along its length. The dividing segment is non-magnetic. The first segment includes a first magnetic attraction surface and a second magnetic attraction surface that are oppositely arranged and have opposite magnetic properties. The second segment includes a third magnetic attraction surface and a fourth magnetic attraction surface that are oppositely arranged and have opposite magnetic properties. The first segment is folded along the dividing segment and stacked on the second segment. The first magnetic attraction surface faces the third magnetic attraction surface, and the first magnetic attraction surface and the third magnetic attraction surface are magnetically attracted to each other.

[0008] The magnetically absorbent data cable provided in this application can be folded for storage. In the folded state, the first and second segments attract each other, and the user can adjust the length of the data cable according to the actual usage scenario. In the stored state, the user can fold the first and second segments and then coil them into a shape, making the data cable more neat and compact after storage. Since the first magnetic surface of the first segment can magnetically attract the third magnetic surface of the second segment, the user can achieve automatic magnetic attraction of the data cable after folding the cable bundle, making the data cable neater and improving the convenience of cable bundle organization and storage.

[0009] In some embodiments, the magnetically absorbed data cable is wound into a disc shape, and the second magnetic surface is stacked on the fourth magnetic surface along the winding direction and magnetically attracted to the fourth magnetic surface.

[0010] In some embodiments, the magnetically absorbed data cable is wound and stored in a disc shape, starting from the end where the dividing segment is located.

[0011] In the above solution, the magnetic absorption data cable is wound into a disc shape, which makes the data cable more neat and convenient to carry after storage.

[0012] In some embodiments, the connectors at both ends of the cable are exposed outside the disc-shaped body formed by winding and storing the magnetically absorbed data cable.

[0013] In the above solution, when using it, the data cable can be quickly unfolded by pulling the connector protruding from the disc-shaped body, making it convenient to use.

[0014] In some embodiments, the connector includes a plug body connected to the cable and a plug portion protruding from the plug body, wherein the inner surface of the plug body is configured as an arc-shaped concave surface, and the inner surface is one side surface facing the center of the disc-shaped body formed by the magnetic absorption data cable being wound and stored.

[0015] In the above solution, the inner surface of the plug-in body is constructed as an arc-shaped concave surface, which can fit more closely with the outer surface of the disc-shaped body, and the data cable is neater after being stored.

[0016] In some embodiments, the outer surface of the plug-in body is configured as an arcuate convex surface, the outer surface being the side surface away from the center of the disc-shaped body formed by the magnetic absorption data cable being wound and stored.

[0017] In some embodiments, the connector body is provided with a magnetic connector that magnetically attracts the cable. Understandably, because the connector body has a magnetic connector, it can magnetically attract the cable, resulting in a neater cable bundle.

[0018] In some embodiments, the first segment is pre-bent relative to the second segment along the dividing segment, and the first magnetic attraction surface forms a first pre-compression angle relative to the third magnetic attraction surface, the first pre-compression angle being less than or equal to 90°.

[0019] In the above scheme, since a first pre-compression angle is formed between the first magnetic attraction surface and the third magnetic attraction surface, the existence of the first pre-compression angle is beneficial for the user to quickly wind and shape the wire harness.

[0020] In some embodiments, the first segment includes a pre-compression segment and a winding segment, the pre-compression segment being connected between the separating segment and the winding segment, the winding segment being pre-compression bent relative to the pre-compression segment along the winding direction, and the second magnetic attraction surface of the winding segment forming a second pre-compression angle relative to the second magnetic attraction surface of the pre-compression segment, the second pre-compression angle being less than or equal to 90°.

[0021] In some embodiments, the wire is a flat wire. The first and second segments of the wire are more easily magnetically attracted to each other, and the wire bundle is more neat and orderly after being attracted together.

[0022] In some embodiments, the first segment further includes a first surface and a second surface connected between the first magnetic surface and the second magnetic surface, and the second segment further includes a third surface and a fourth surface connected between the third magnetic surface and the fourth magnetic surface, wherein the area of ​​the first magnetic surface is larger than the area of ​​the first surface, and the area of ​​the third magnetic surface is larger than the area of ​​the third surface.

[0023] In the above scheme, since the area of ​​the first magnetic attraction surface is larger than the area of ​​the first surface, the first segment and the second segment of the wire are more easily magnetically attracted along the larger area of ​​the first magnetic attraction surface, and the wire bundle is more neat and orderly after being attracted together.

[0024] In some embodiments, the wire body includes, from the inside out, a plurality of core wires and an insulating layer covering the plurality of core wires, the insulating layer containing magnetic powder.

[0025] In some embodiments, the wire body further includes a protective layer located outside the insulation layer.

[0026] In the above solution, the protective layer is wrapped around the insulation layer. The protective layer can improve the service life of the insulation layer, protect the insulation layer from damage, and enhance the durability of the data cable.

[0027] In some embodiments, a fireproof layer is further provided between the insulating layer and the protective layer.

[0028] In the above solution, the addition of a fireproof layer can reduce the probability of the data cable spontaneously combusting at high temperatures, thereby improving the safety of the data cable.

[0029] In some embodiments, one end of the cable is provided with a connector plug, and the other end is provided with at least two connector plugs, which are electrically connected to the cable respectively.

[0030] In the above solution, the data cable can be adapted to more electronic device connectors, thus expanding the scope of application of the data cable.

[0031] In some embodiments, the dividing segment is located in the middle of the line along the length direction, and the length of the dividing segment is 0.2cm to 1cm.

[0032] After adopting the above technical solution, this application has at least the following technical effects compared with the prior art:

[0033] The magnetically absorbent data cable provided in this application can be folded for storage. In the folded state, the first and second segments attract each other, and the user can adjust the length of the data cable according to the actual usage scenario. In the stored state, the user can fold the first and second segments and then coil them into a shape, making the data cable more neat and compact after storage. Since the first magnetic surface of the first segment can magnetically attract the third magnetic surface of the second segment, and the second magnetic surface can magnetically attract the fourth magnetic surface, the user can achieve automatic magnetic attraction of the data cable after folding the cable bundle, making the data cable more neat and improving the convenience of cable bundle organization and storage.

Embodiments of the present invention

[0050] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0051] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0052] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0053] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0054] This application provides a magnetic absorption data cable. Figure 1 is a schematic diagram of the structure of the magnetic absorption data cable provided in Embodiment 1 of this application. As shown in Figure 1, the magnetic absorption data cable includes a cable body 10 and connecting plugs 20 located at both ends of the cable body 10.

[0055] The line 10 includes a first segment 11, a dividing segment 13, and a second segment 12 connected sequentially along its length. The dividing segment 13 is non-magnetic. The first segment 11 includes a first magnetic attraction surface 111 and a second magnetic attraction surface 112 that are arranged opposite to each other and have opposite magnetic properties. The second segment 12 includes a third magnetic attraction surface 121 and a fourth magnetic attraction surface 122 that are arranged opposite to each other and have opposite magnetic properties. The first segment 11 is folded along the dividing segment 13 and stacked on the second segment 12. The first magnetic attraction surface 111 faces the third magnetic attraction surface 121 and the first magnetic attraction surface 111 and the third magnetic attraction surface 121 are magnetically attracted to each other.

[0056] The magnetically absorbent data cable provided in this application can be folded for storage. In the folded state, the first and second segments attract each other, and the user can adjust the length of the data cable according to the actual usage scenario. In the stored state, the user can fold the first and second segments and then coil them into a shape, making the data cable more neat and compact after storage. Since the first magnetic surface of the first segment can magnetically attract the third magnetic surface of the second segment, and the second magnetic surface can magnetically attract the fourth magnetic surface, the user can achieve automatic magnetic attraction of the data cable after folding the cable bundle, making the data cable more neat and improving the convenience of cable bundle organization and storage.

[0057] As shown in Figure 1, the magnetic absorption data cable includes a cable body 10 and connectors 20 located at both ends of the cable body 10. The connectors 20 can be MICRO USB connectors, LIGHTNING connectors, or USB Type-C connectors. The connector plug, etc., can adapt to the charging needs of various devices. For example, connector plug 20 can be two identical lightning plugs.

[0058] Please refer to Figure 1. Along the length direction, the wire 10 includes a first segment 11, a dividing segment 13, and a second segment 12 that are connected. It should be noted that there is no obvious dividing line between the first segment 11, the second segment 12, and the dividing segment 13. The length of the first segment 11 can be the same as or different from that of the second segment 12. In order to stagger the two connecting plugs in the winding state, the length of the first segment 11 is different from that of the second segment 12. The length difference can be 1cm to 5cm, and no limitation is made here.

[0059] In some embodiments, the dividing segment 13 is located at the middle of the line body 10 along its length, with the first segment 11 and the second segment 12 located on either side of the dividing segment 13. The dividing segment 13 is non-magnetic, allowing the first segment 11 and the second segment 12 to each have independently set different magnetic poles. Furthermore, by using a non-magnetic dividing segment, the magnetic poles of the first and second segments can be effectively isolated, preventing their magnetic fields from interfering with each other. This maintains the independence and stability of the magnetic field in each part.

[0060] Specifically, the length L of the dividing segment can be 0.2cm to 1cm, such as 0.2cm, 0.5cm, 0.8cm, or 1cm, etc., and is not limited here. If the length of the dividing segment is too large, the central hole will be too large during winding, resulting in an increase in the diameter of the data cable after winding. If the length of the dividing segment is too small, the processing precision requirements are high, and the process is difficult.

[0061] Furthermore, the dividing segment 13 can be located within ±3cm of the middle of the thread 10 along the length direction. In this way, the lengths of the first segment 11 and the second segment 12 tend to be consistent after folding, and most of the thread can be attracted to each other after winding, which is more conducive to storage.

[0062] Figure 2 is a schematic diagram of the magnetic pole distribution of the magnetic absorption nanodata line provided in Embodiment 1 of this application. As shown in Figure 2, the line body 10 is a flat line body. The first magnetic absorption surface 111 of the first segment 11 has an S pole, and the second magnetic absorption surface 112 has an N pole. The third magnetic absorption surface 121 of the second segment 12 has an N pole, and the fourth magnetic absorption surface 122 has an S pole.

[0063] In other embodiments, the first magnetic surface 111 may have an N pole, the second magnetic surface 112 may have an S pole, the third magnetic surface 121 of the second segment 12 may have an S pole, and the fourth magnetic surface 122 may have an N pole; this is not limited here. Understandably, it is sufficient that the magnetism of adjacent magnetic surfaces of the wire body is different in the folded state. Due to the different magnetism, adjacent first and second segments will be magnetically attracted to each other, thereby enabling quick wire storage and improving the user experience.

[0064] Figure 3 is a schematic diagram of the storage state of the magnetic absorption data cable provided in Embodiment 1 of this application. As shown in Figures 2 and 3, in the storage state, the magnetic absorption data cable is wound into a disc shape, and the second magnetic surface 112 is stacked on the fourth magnetic surface 122 along the winding direction and magnetically attracted to the fourth magnetic surface 122. Specifically, the magnetic absorption data cable is wound into a disc shape starting from the end where the dividing segment 13 is located. The connectors 20 at both ends of the cable body 10 are exposed outside the disc-shaped body formed by the winding of the magnetic absorption data cable. As shown in Figure 2, in use, the user only needs to pull the connectors 20 exposed outside the disc-shaped body to quickly unfold the data cable, making it convenient to use.

[0065] To facilitate quick winding and storage of the magnetically absorbed data cable, as shown in Figures 3 and 4, the first segment 11 is pre-bent relative to the second segment 12 along the dividing segment 13, and the first magnetic surface 111 forms a first pre-compression angle 110 relative to the third magnetic surface 121. The first pre-compression angle 110 is less than or equal to 90°, and can specifically be 90°, 80°, 70°, 60°, etc., without limitation. For example, the magnetically absorbed data cable can be pre-bent to form the first pre-compression angle 110 through a hot-pressing process. Because the first pre-compression angle 110 is formed between the first and third magnetic surfaces, it facilitates quick winding and shaping of the cable harness by the user.

[0066] Figure 4 is a schematic diagram of the storage state of the magnetic absorption data cable provided in Embodiment 1 of this application. As shown in Figure 4, in some embodiments, the first segment 11 includes a pre-compression segment 11a and a winding segment 11b. The pre-compression segment 11a is connected between the separating segment 13 and the winding segment 11b. The winding segment 11b is pre-compressed and bent relative to the pre-compression segment 11a along the winding direction, and the second magnetic attraction surface of the winding segment 11b forms a second pre-compression angle 120 relative to the second magnetic attraction surface of the pre-compression segment 11a. The second pre-compression angle 120 is less than or equal to 90°. With the combined action of the first pre-compression angle 110 and the second pre-compression angle 120, the user can quickly wind and store the magnetic absorption data cable. After storage, the overall structure is compact and orderly, making it convenient to carry. Furthermore, since the first segment of this application can be magnetically attracted to the second segment after folding, the thickness of the magnetically absorbed data cable does not increase. The thickness after storage is comparable to the width of the cable bundle. Due to the different length designs of the data cable, the diameter D of the rolled-up disc-shaped magnetically absorbed data cable also varies. Compared to data cables that are stacked and wound along the thickness direction, the magnetically absorbed data cable provided by this application is more regular and orderly in its stored state. The thickness of the rolled-up disc-shaped data cable is the same as or nearly the same as the width of the cable body. Users can reduce the space required for storage during travel or storage, thus improving portability.

[0067] Figure 5 is a cross-sectional schematic diagram of the magnetically absorbed data cable provided in Embodiment 1 of this application. As shown in Figure 5, the cross-section of the cable 10 is approximately square, and the areas of the first magnetic surface 111 and the second magnetic surface 112 are approximately the same. The first segment 11 also includes a first surface 113 and a second surface 114 connected between the first magnetic surface 111 and the second magnetic surface 112. The areas of the first surface 113 and the second surface 114 are approximately the same. The areas of the first magnetic surface 111 and the second magnetic surface 112 are larger than the areas of the first surface 113 and the second surface 114, respectively. In the above scheme, since the areas of the first magnetic surface 111 and the second magnetic surface 112 are larger, the magnetic attraction is greater than that of the first and second surfaces on the sides. As long as the distance between the first segment and the second segment of the cable is appropriate, automatic adsorption can be achieved. During the winding process, the cable can also be wound along the first magnetic surface, which is beneficial for quick storage.

[0068] Similarly, the second segment 12 also includes a third surface and a fourth surface connected between the third magnetic surface 121 and the fourth magnetic surface 122. The areas of the third surface and the fourth surface are approximately the same, and the areas of the third magnetic surface 121 and the fourth magnetic surface 122 are respectively larger than the areas of the third surface and the fourth surface.

[0069] Please refer to Figure 5. The wire body 10 includes a plurality of core wires 101 from the inside out and an insulating layer 102 covering the plurality of core wires 101. The insulating layer 102 contains magnetic powder.

[0070] The insulating layer 102 can be formed by extrusion molding of a mixture of plastic and magnetic powder, and further magnetized to give it magnetic attraction. After magnetization, the magnetic powder located at the first magnetic attraction surface 111 and the magnetic powder located at the second magnetic attraction surface 112 in the insulating layer 102 have different magnetic properties, the magnetic powder located at the third magnetic attraction surface 121 and the magnetic powder located at the fourth magnetic attraction surface 122 have different magnetic properties, and the magnetic powder located at the first magnetic attraction surface 111 and the magnetic powder located at the third magnetic attraction surface 121 have the same magnetic properties.

[0071] In some embodiments, the cable body 10 further includes a protective layer 103 located outside the insulation layer 102. The protective layer 103 wraps around the insulation layer 102, and the provision of the protective layer 103 can improve the service life of the insulation layer 102, protect the insulation layer 102 from damage, and enhance the durability of the data cable.

[0072] The protective layer 103 can be a braided layer formed by weaving, and the material of the braided material can be a polymer, such as polyethylene, polypropylene, rubber, etc. The braided layer has a certain degree of flexibility and tensile strength, which can further protect the data cable, reduce the impact of external substances on the insulation layer, reduce the decrease in magnetic attraction of the insulation layer 102 due to friction, scratches, etc. The braided layer can also reduce the tangling and twisting of the data cable, and improve the durability of the data cable.

[0073] Figure 6 is another cross-sectional schematic diagram of the magnetic absorption data cable provided in Embodiment 1 of this application. As shown in Figure 6, a fireproof layer 104 is also provided between the insulation layer 102 and the protective layer 103. The fireproof layer 104 covers the surface of the insulation layer 102. Since the fireproof layer 104 can improve the fire resistance of the data cable, it can reduce the probability of the data cable spontaneously combusting at high temperatures and improve the safety of the data cable.

[0074] In some implementations, the protective layer 103 can also be a waterproof layer, which can prevent moisture from entering the data cable and affecting the safety of the data cable.

[0075] Furthermore, one end of the magnetic absorption data cable 10 is provided with a connector 20, and the other end is provided with at least two connectors 20, which are electrically connected to the cable 10 respectively.

[0076] Figure 7 is a schematic diagram of the winding state of the magnetic absorption data cable provided in Embodiment 2 of this application. As shown in Figure 7, one end of the cable body 10 is provided with two connectors 20, which can be a Lightning connector and a USB Type connector, respectively. c. Connector plug.

[0077] Figure 8 is a schematic diagram of the winding state of the magnetic absorption data cable provided in Embodiment 3 of this application. As shown in Figure 8, one end of the cable body 10 is provided with three connectors 20, which can be a MICRO USB connector, a LIGHTNING connector, and a USB Type connector, respectively. The C connector plug enables the data cable to be multifunctional, allowing it to be compatible with different electronic devices and expanding its application range.

[0078] Figure 9 is a schematic diagram of the connector of the magnetic absorption data cable provided in Embodiment 4 of this application. As shown in Figure 9, the connector 20 includes a plug body 22 connected to the cable body 10 and a plug portion 21 protruding from the plug body.

[0079] In this embodiment, the inner surface 221 of the plug-in body 22 is constructed as an arc-shaped concave surface, and the inner surface 221 is the side surface facing the center of the disc-shaped body formed by winding and storing the magnetically absorbed data cable. In the winding state, the arc-shaped concave surface of the plug-in body 22 can fit more closely with the outer surface of the disc-shaped body, and the stored data cable is more neat.

[0080] To facilitate a more stable fixation of the connector 20, a magnetic connector (not shown) is provided inside the plug body 22, which magnetically attracts the cable 10. In the wound-up storage state, the connector 20 can also magnetically attract the cable 10, resulting in a more neat and orderly overall appearance.

[0081] In some embodiments, the outer surface 222 of the plug-in body 22 is constructed as an arc-shaped convex surface, which is the side surface away from the center of the disc-shaped body formed by the magnetic absorption data cable being wound and stored. This design can improve the aesthetics of the entire connector. As shown in Figure 2, the magnetic absorption data cable provided in this application can, in the use state, be magnetically attracted by folding the first segment 11 and the second segment 12 together with the separator segment 13 as the center, and then wound up, according to the distance between the charging plug and the electronic device. The length of the first segment 11 and the second segment 12 is reserved according to the required distance, which can achieve orderly storage of the cable bundle in the use state and improve the tidiness of the desktop. As shown in Figure 3, in the storage state, the first segment 11 and the second segment 12 are magnetically attracted by folding them together with the separator segment 13 as the center, and then wound up and stored into a disc shape, which can make the data cable more neat and compact after storage, easy to carry, and improve the convenience of use.

[0082] As shown in Figures 10-13, in one embodiment of this application, the magnetic absorption data cable includes a cable body 10 and a connector 20 connected to the end of the cable body 10. The cable body 10 includes a core wire 101 and an insulating layer 102. The insulating layer 102 is arranged in parallel with the core wire 101. The insulating layer 102 includes a plurality of folded segments 123 arranged sequentially along its length and an elastic bending segment 124 for connecting two adjacent folded segments 123. The folding shape of two adjacent folded segments 123 ultimately determines the storage folding shape of the magnetic absorption data cable. The elastic bending segment 124 is pre-shaped and bent (as shown in Figure 11). The cable body 10 also includes a protective layer 103, which covers the periphery of the insulating layer 102 and the core wire 101. The protective layer 103 includes a magnetic absorption layer.

[0083] In the above technical solution, the insulating layer 102 includes a plurality of folded segments 123 arranged sequentially along its length and an elastically bent segment 124 connecting two adjacent folded segments. That is, the insulating layer 102 is composed of segments of different types connected together. The elastically bent segment 124 is pre-shaped and bent. After being stretched, the elastically bent segment 124 has a restoring elastic force that returns to its pre-shaped bent form (as shown in Figure 11). When the two ends of the magnetic absorption data cable are pulled, the two adjacent folded segments 123 and the elastically bent segment 124 are pulled apart by an angle. After being stretched, the two adjacent folded segments 123 can retract and fold back to a certain angle without being subjected to a tensile force, relying on the restoring elastic force of the elastically bent segment 124. At this time, the elastically bent segment 124 returns to its pre-shaped bent form (as shown in Figure 11). The two adjacent folding segments are then magnetically attached together by the magnetic layer to fold, making the entire storage process fully automatic without manual intervention. The adjacent folding segments 123 can fit tightly together, allowing the data cable to be automatically folded into a compact state when not in use, greatly reducing the volume of the data cable after storage. This makes it convenient for users to put it into small spaces such as backpacks and pockets, avoiding the inconvenience and space-consuming problems caused by tangling of traditional data cables. The entire storage process does not require manual intervention, providing users with a more convenient user experience and saving users time and effort in organizing and storing data cables. The pre-shaped elastic bending segment 124 provides a stable support point for the folding of the data cable, allowing the folded data cable to maintain a neat and regular shape without wrinkles or twists, further improving the storage effect and aesthetics of the data cable.

[0084] As shown in Figure 13, in one embodiment of this application, the insulating layer 102 is a covering layer that covers the core wire 101. In other embodiments, the insulating layer 102 may also include at least one linear skeleton disposed on the outside of the core wire 101. The insulating layer 102 is designed to support the folded shape of the core wire 101. There is no restriction that the insulating layer 102 must be a covering structure, which provides multiple options. The appropriate insulating layer 102 structure can be selected according to different usage requirements and application scenarios. The covering layer structure can better protect the core wire 101 and prevent it from being worn and interfered with by the outside world.

[0085] As shown in Figure 13, in one embodiment of this application, the cable 10 further includes a protective layer 103. The protective layer 103 covers the periphery of the insulation layer 102. The protective layer 103 provides an additional layer of protection for the insulation layer 102 and the core wire 101, which can effectively prevent external physical damage, such as friction, scratches, and squeezing. It can also resist the influence of external environmental factors, such as dust, moisture, and chemical corrosion, thereby further extending the service life of the data cable and improving its reliability in various complex environments.

[0086] In one embodiment of this application, the protective layer 103 includes a magnetic layer, which is made of samarium iron nitride magnetic material or samarium iron nitride magnetic material with flame retardant properties (the detailed manufacturing process has been disclosed in Chinese patent application number 202410975794.7, which will not be repeated here). The magnetic layer allows two adjacent folded segments 123 to be attracted to each other and folded. More specifically, two adjacent folded segments 123 are magnetically attached through the magnetic layers at their respective middle ends, and the magnetic poles of the magnetic layers at the middle ends of the two adjacent folded segments 123 are opposite, so that the adsorption and folding can be completed with the fewest magnetic layers. The magnetic layer is made of samarium iron nitride magnetic material with flame retardant properties, and the insulating layer 102 also has flame retardant properties, which improves the safety of the data cable. In other embodiments, the protective layer 103 may also include a braided layer or only include a braided layer. The braided layer is made of fibrous material to improve the toughness of the data cable. When the protective layer 103 only includes a braided layer, two adjacent folded segments 123 are magnetically attached by magnetic attractors at their respective middle ends.

[0087] In one embodiment of this application, the insulation layer 102 is made of thermoplastic polyurethane or thermoplastic polyurethane with flame-retardant properties (the detailed manufacturing process has been disclosed in Chinese patent application number 201510630909.X, which will not be repeated here). Thermoplastic polyurethane has good physical properties such as elasticity, wear resistance, oil resistance and low temperature resistance, which enables the insulation layer 102 to maintain stable performance in various environments, ensuring that the data cable will not experience aging, wear, or breakage during long-term use, thereby extending the service life of the data cable. Thermoplastic polyurethane with flame-retardant properties can effectively prevent the spread of fire, reduce the burning speed and heat release of the data cable in dangerous situations such as fires, buy users more escape time and reduce fire losses, and improve the safety of the data cable during use. In addition, since the insulation layer 102 is made of thermoplastic polyurethane, the elastic bending section 124 can be easily pre-shaped by heating and bent. After being stretched, the elastic bending section 124 can have the restoring elasticity to return to the pre-shaped bending form (as shown in the bending state in Figure 11).

[0088] As shown in Figure 12, in one embodiment of this application, the cable 10 further includes a magnetic attractor 14 disposed at each of the folded segments 123. The magnetic attractors 14 on two adjacent folded segments 123 are correspondingly arranged. More specifically, a plurality of magnetic attractors 14 are equally spaced along the length extension direction of each folded segment 123. The equally spaced plurality of magnetic attractors 14 can make the magnetic attraction force between adjacent folded segments 123 more uniform, thereby improving the stability of adsorption and avoiding the phenomenon of loosening or misalignment between folded segments 123 due to uneven magnetic attraction force, ensuring that the data cable always remains neat and compact during storage. In other embodiments, a magnetic attractor 14 is provided at the middle of each folded segment 123, which can complete the adsorption folding with the minimum number of magnets to assist the magnetic attractor layer.

[0089] As shown in Figure 12, in one embodiment of this application, the magnetic chuck 14 is ring-shaped and is a magnet. The magnetic chuck 14 is built into the wire body 10. The magnetic poles of the magnetic chuck 14 at the corresponding locations of two adjacent folded segments 123 are opposite. The ring-shaped magnetic chuck 14 is built into the wire body 10, making the overall structure of the data cable more compact without adding extra volume. At the same time, it does not affect the appearance and normal use of the data cable, achieving a perfect integration of magnetic attraction function and data cable structure. In other embodiments, the magnetic chuck 14 can be sleeved on the outside of the wire body 10, and the setting method is simple and flexible.

[0090] As shown in Figure 13, in one embodiment of this application, the core wire 101 includes signal lines 115 and power lines 116. In another embodiment, the core wire 101 includes three signal lines 115 and two power lines 116, which are arranged side by side, with the signal lines 115 positioned between the power lines 116. This arrangement of the signal lines 115 and power lines 116 facilitates a one-to-one correspondence between the signal lines 115 and standard pins, preventing jumper issues. Furthermore, it eliminates the need for pre-embedded wiring during data cable manufacturing, reducing manufacturing steps and simplifying processing.

[0091] As shown in Figure 13, in one embodiment of this application, the insulating layer 102 is a covering layer that simultaneously covers the signal line 115 and the two power lines 116. Of course, in other embodiments, the insulating layer 102 may also be a covering layer that separately covers the signal line 115 and the two power lines 116, which can be set according to actual needs.

[0092] As shown in Figure 13, in one embodiment of this application, the core diameter of the power cord 116 is larger than that of the signal cord 115. The power cord 116 is an enameled wire, and the outer surface of the core of the power cord 116 is provided with an insulating varnish layer. The insulating varnish layer of the enameled wire is relatively thin. Compared with other types of power cords, it can effectively reduce the cross-sectional size of the wire body 10 while ensuring conductivity, thereby making the data cable thinner and lighter, easier to store and carry, and also reducing the volume of the wire body 10 after folding, further improving the storage effect, saving the amount of material used in the wire body 10, and reducing the manufacturing cost of the wire body 10.

[0093] As shown in Figures 10-11, in one embodiment of this application, each of the folded segments 123 is of equal length, requiring less space after the cable 10 is stored, and is easy to fold by adsorption. The equal-length folded segments 123 can form a neat and regular folded shape when stored, making the data cable look more beautiful and tidy, improving the appearance quality of the product, and also making it easier for users to quickly find the required part during storage and use. The cross-sectional shape of the cable 10 is rectangular, which allows the data cable to better fit the shape of the storage space after folding, further improving space utilization. In other embodiments, the cross-sectional shape of the cable 10 can also be circular. The type of the connector 20 is a Type-C connector. As a widely used connector standard, the Type-C connector has advantages such as reversible insertion, fast transmission speed, and support for multiple functions. It is compatible with most modern electronic devices and meets the user's needs for data transmission and charging between different devices. In other embodiments, the connector 20 can be either a USB-A connector or a Lightning connector.

[0094] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
