Description

Technical Field

[0001] This utility model relates to the field of data cable technology, and in particular to a magnetic data cable. Background Technology

[0002] The emergence of data cables aims to meet the dual needs of data transmission and charging between electronic devices. Through an internal conductive cable and an external interface, they connect devices to power sources or other equipment, enabling efficient data transmission and a stable power supply. However, data cables are typically designed to be quite long, such as 1.5 meters, for ease of connection and use, which can make data cable storage inconvenient. In response, segmented magnetic self-folding data cables have emerged to address this issue. For example, Chinese utility model patent (publication number: CN 212011529U) discloses a segmented magnetic self-folding data cable. Its technical solution involves installing a magnet at each end of each bending section of the data cable. Adjacent bending sections attract and fold together via their respective magnets, achieving automatic data cable storage. However, this design has limitations: adjacent bending sections only automatically attract when they reach a certain distance. Initially, the adjacent bending sections still need to be manually adjusted to this specific distance to complete the subsequent automatic attraction process. Therefore, existing segmented magnetic retractable data cables still require manual operation before achieving automatic retraction, and cannot achieve fully automatic retraction. Utility Model Content

[0003] The purpose of this invention is to provide a magnetic data cable that can be automatically stored, so as to avoid the need for manual operation before the data cable can be automatically stored.

[0004] To achieve the above objectives, the technical solution of this utility model embodiment is as follows:

[0005] A magnetic data cable includes a cable body and an interface connected to the end of the cable body;

[0006] The wire body includes a conductive cable and a skeleton layer. The skeleton layer is arranged in parallel with the conductive cable. The skeleton layer includes a plurality of folded segments arranged sequentially along the length extension direction and an elastic bending segment for connecting two adjacent folded segments.

[0007] The wire body also includes an outer sheath layer, which covers the skeleton layer and the outer periphery of the conductive cable;

[0008] The outer sheath includes a magnetic layer, and two adjacent folded segments are folded together by magnetic attraction through the magnetic layer.

[0009] Furthermore,

[0010] The skeleton layer is a covering layer that covers the conductive cable;

[0011] Alternatively, the skeleton layer may include at least one linear skeleton disposed on the outside of the conductive cable.

[0012] Furthermore,

[0013] Two adjacent folded segments are magnetically attached to each other through magnetic layers at their respective midpoints, and the magnetic poles of the magnetic layers at the midpoints of the two adjacent folded segments are opposite.

[0014] Furthermore,

[0015] The outer sheath includes a woven layer made of fibrous material, which covers the magnetic layer; and / or, the skeleton layer is made of thermoplastic polyurethane.

[0016] Furthermore,

[0017] The conductive cable includes a signal line and two power lines, which are arranged side by side, with the signal line positioned between the two power lines.

[0018] Furthermore,

[0019] The skeleton layer is a covering layer that simultaneously covers the signal line and two power lines;

[0020] Alternatively, the skeleton layer may be a covering layer that covers the signal line and the two power lines respectively.

[0021] Furthermore,

[0022] The core diameter of the power line is larger than that of the signal line.

[0023] And / or, the outer surface of the power cord core is provided with an insulating varnish layer.

[0024] Furthermore,

[0025] The line body also includes a magnetic attractor located at each of the folded segments, with the magnetic attractors on two adjacent folded segments being arranged correspondingly.

[0026] Furthermore,

[0027] A magnetic closure is provided at the middle of each of the folded sections;

[0028] Alternatively, each of the folded segments may be provided with a plurality of magnetic attractors at equal intervals along the length of the folded segment.

[0029] Furthermore,

[0030] The magnetic attractor is ring-shaped and is either built into the wire body or sleeved on the wire body. The magnetic poles of the magnetic attractors at the corresponding locations of two adjacent folded segments are opposite.

[0031] Compared with the prior art, the embodiments of this utility model have at least the following technical effects:

[0032] The magnetic data cable of this utility model embodiment includes a cable body and an interface connected to the end of the cable body. The cable body includes a conductive cable and a skeleton layer. The skeleton layer is arranged in parallel with the conductive cable. The skeleton layer includes a plurality of folded segments arranged sequentially along its length and an elastic bending segment for connecting two adjacent folded segments. The cable body also includes an outer sheath layer, which covers the skeleton layer and the conductive cable. The outer sheath layer includes a magnetic layer. The folding shape of two adjacent folded segments is used to determine the storage folding shape of the magnetic data cable. The elastic bending segment is pre-shaped and bent. After being stretched, the elastic bending segment has the elasticity to return to the pre-shaped bent state. After being stretched, two adjacent folded segments can first retract and fold a certain angle by relying on the recovery elasticity of the elastic bending segment without being subjected to external stretching force. At this time, the elastic bending segment returns to the pre-shaped bent state. The two adjacent folded segments are then magnetically attached by the magnetic layer and completely folded. The entire storage process of the data cable is fully automatic and does not require manual intervention. Attached Figure Description

[0042] like Figure 1-4 As shown, in one embodiment of this utility model, the magnetic data cable includes a cable body 10 and an interface 20 connected to the end of the cable body 10. The cable body 10 includes a conductive cable 11 and a skeleton layer 12. The skeleton layer 12 is arranged parallel to the conductive cable 11. The skeleton layer 12 includes a plurality of folded segments 120 arranged sequentially along its length direction and an elastic bending segment 121 for connecting two adjacent folded segments 120. The folding shape of two adjacent folded segments 120 ultimately determines the storage folding shape of the magnetic data cable. The elastic bending segment 121 is pre-shaped and bent (e.g., ...). Figure 2 As shown), the wire body 10 also includes an outer sheath layer 14, which covers the periphery of the skeleton layer 12 and the conductive cable 11, and the outer sheath layer 14 includes a magnetic layer.

[0043] In the above technical solution, the skeleton layer 12 includes a plurality of folded segments 120 arranged sequentially along its length and an elastically bent segment 121 connecting two adjacent folded segments. That is, the skeleton layer 12 is composed of segments of different types connected together. The elastically bent segment 121 is pre-shaped and bent, and after being stretched, it returns to its pre-shaped bent form (e.g., ...). Figure 2The elastic force of the bending state shown indicates that when the two ends of the magnetic data cable are pulled, the two adjacent folded segments 120 and the elastic bending segment 121 will be stretched apart. After being stretched, the two adjacent folded segments 120 can retract and fold back to a certain angle without being subjected to external stretching force, relying on the elastic force of the elastic bending segment 121. At this time, the elastic bending segment 121 returns to the pre-designed bending shape (such as...). Figure 2 (As shown in the bending state), then the two adjacent folded segments are magnetically attached together by the magnetic layer and folded. The entire storage process is fully automatic and requires no manual intervention. The adjacent folded segments 120 can fit tightly together, so that the data cable can be automatically folded into a compact state when not in use, which greatly reduces the volume of the data cable after storage. It is convenient for users to put it into small spaces such as backpacks and pockets, avoiding the problems of inconvenience and large space occupation caused by the 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 121 provides a stable support point for the folding of the data cable, so that the folded data cable can maintain a neat and regular shape without wrinkles, twists, or other phenomena, further improving the storage effect and aesthetics of the data cable.

[0044] like Figure 4 As shown, in one embodiment of this utility model, the skeleton layer 12 is a covering layer that covers the conductive cable 11. In other embodiments, the skeleton layer 12 may also include at least one linear skeleton disposed on the outside of the conductive cable 11. The skeleton layer 12 is designed to support the folded shape of the conductive cable 11. It is not limited to the skeleton layer 12 being a covering structure, which provides multiple options. The appropriate skeleton layer 12 structure can be selected according to different usage requirements and application scenarios. The covering layer structure can better protect the conductive cable 11 and prevent it from being worn and interfered with by the outside world.

[0045] like Figure 4 As shown, in one embodiment of this utility model, the cable body 10 further includes an outer sheath layer 14, which covers the periphery of the skeleton layer 12. The outer sheath layer 14 provides an additional layer of protection for the skeleton layer 12 and the conductive cable 11, effectively preventing 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.

[0046] In one embodiment of this utility model, the outer sheath 14 includes a magnetic layer, which is made of samarium iron nitride (SMR) magnetic material or a SMR magnetic material with flame-retardant properties (the detailed manufacturing process is disclosed in Chinese patent application number 202410975794.7, which will not be repeated here). The magnetic layer allows two adjacent folded segments 120 to be attracted to each other and folded. The magnetic layer uses a SMR magnetic material with flame-retardant properties, and the skeleton layer 12 also has flame-retardant properties, which improves the safety of the data cable. In other embodiments, the outer sheath 14 also includes a braided layer or only includes a braided layer. The braided layer is made of woven fiber material, which improves the toughness of the data cable. More specifically, two adjacent folded segments 120 are magnetically attached through the magnetic layers at their respective middle ends, and the magnetic poles of the magnetic layers at the corresponding middle ends of the two adjacent folded segments 120 are opposite, so that the adsorption and folding can be completed with the fewest magnetic layers.

[0047] In one embodiment of this utility model, the skeleton layer 12 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, enabling the skeleton layer 12 to maintain stable performance in various environments. This ensures that the data cable will not experience aging, wear, or breakage during long-term use, thereby extending the data cable's lifespan. Thermoplastic polyurethane with flame-retardant properties can effectively prevent the spread of fire, reduce the burning rate and heat release of the data cable in dangerous situations such as fires, provide users with more escape time, reduce fire losses, and improve the safety of the data cable during use. Furthermore, since the skeleton layer 12 is made of thermoplastic polyurethane, the elastic bending section 121 is easily pre-shaped by heating and can return to its pre-shaped bending form after being stretched (e.g., ...). Figure 2 The restoring elasticity (as shown in the bent state).

[0048] like Figure 3As shown, in one embodiment of this utility model, the cable body 10 further includes a magnetic suction member 13 disposed at each of the folded segments 120. The magnetic suction members 13 on two adjacent folded segments 120 are correspondingly arranged. More specifically, a plurality of magnetic suction members 13 are equally spaced along the length extension direction of each folded segment 120. The equally spaced plurality of magnetic suction members 13 can make the magnetic attraction force between adjacent folded segments 120 more uniform, thereby improving the stability of adsorption and avoiding the phenomenon of loosening or misalignment between folded segments 120 due to uneven magnetic attraction force, ensuring that the data cable always remains neat and compact during storage. In other embodiments, a magnetic suction member 13 is provided at the middle of each folded segment 120, which can complete the adsorption folding with the minimum number of magnets to assist the magnetic suction layer.

[0049] like Figure 3 As shown, in one embodiment of this utility model, the magnetic chuck 13 is ring-shaped and is a magnet. The magnetic chuck 13 is built into the cable body 10. The magnetic poles of the magnetic chuck 13 at the corresponding locations of two adjacent folded segments 120 are opposite. The ring-shaped magnetic chuck 13 is built into the cable 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 13 can be sleeved on the outside of the cable body 10, and the setting method is simple and flexible.

[0050] like Figure 4 As shown, in one embodiment of this utility model, the conductive cable 11 includes a signal line 110 and a power line 111. The signal line 110 and the power line 111 are arranged side by side, with the signal line 110 positioned between the power lines 111. This arrangement of the signal line 110 and the power line 111 facilitates a one-to-one correspondence between the signal line 110 and the standard pins, preventing jumpers. Furthermore, it eliminates the need for pre-embedded wiring during data cable manufacturing, reducing manufacturing steps and simplifying processing.

[0051] like Figure 4 As shown, in one embodiment of the present invention, the skeleton layer 12 is a covering layer that simultaneously covers the signal line (110) and the two power lines (111). Of course, in other embodiments, the skeleton layer (12) can also be a covering layer that separately covers the signal line (110) and the two power lines (111), which can be set according to actual needs.

[0052] like Figure 4As shown, in one embodiment of this utility model, the core diameter of the power cord 111 is larger than the core diameter of the signal cord 110. The power cord 111 is an enameled wire, and the outer surface of the core of the power cord 111 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 111, 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. It also reduces the volume of the wire body 10 after folding, further improving the storage effect, and also saving the amount of material used in the wire body 10, reducing the manufacturing cost of the wire body 10. In other embodiments, the core diameter of the power cord 111 is larger than the core diameter of the signal cord 110, and the outer surface of the core of the power cord 111 is provided with an insulating varnish layer. Users can also set it individually according to actual needs.

[0053] like Figure 1-2 As shown, in one embodiment of this utility model, each of the folded segments 120 is of equal length, the space used after the cable body 10 is stored is small, and it is easy to achieve adsorption folding. The folded segments 120 of equal length can form a neat and regular folding 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 body 10 is rectangular. The rectangular cross-sectional shape allows the data cable to better fit the shape of the storage space after folding, further improving the space utilization. In other embodiments, the cross-sectional shape of the cable body 10 can also be circular. The interface type of the interface 20 is a Type-C interface. As a widely used interface standard, the Type-C interface has the advantages of reversible plugging, fast transmission speed, and support for multiple functions. It can be compatible with most modern electronic devices and meet the user's needs for data transmission and charging between different devices. In other embodiments, the interface type of the interface 20 can be either a USB-A interface or a Lightning interface.

[0054] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model shall be determined by the protection scope of the claims.
