[0031] The utility model provides a data cable, comprising a wire body, a first interface and an insulating member, for solving the technical problems in the prior art of large plug-in ends of data cables and inconvenience in use. The data cable has the advantages of compact structure and easy use.

[0032] Please refer to Figure 1-Figure 3 The wire body 10 includes a wrapping layer 11 and a plurality of conductors 12. Along the length of the wire body 10, the conductors 12 include a first portion 121 and a second portion 122. The first portion 121 is enclosed within the wrapping layer 11, and the second portion 122 extends outside the wrapping layer 11, so that the plurality of conductors 12 are integrated together through the wrapping layer 11. The conductors 12 are used for external electrical connection. Along the width direction of the wire body 10, the plurality of conductors 12 are arranged at intervals. The plurality of conductors 12 are staggered in the width direction of the wire body 10, so that the plurality of conductors 12 do not overlap in thickness. By properly arranging the distribution position of the conductors 12, the overall thickness of the wire body 10 can be effectively controlled, thereby achieving a size reduction effect.

[0033] Please refer to Figure 3-Figure 5 The first interface 20 includes a circuit board 21 and a housing 22. The circuit board 21 is mounted within the housing 22. The end of the circuit board 21 near the cable body 10 extends outside the housing 22 and is electrically connected to the second portion 122 of the wire 12. An insulating member 30 covers the housing 22 and circuit board 21 at one end and the cable body 10 at the other end. The insulating member 30 securely connects the cable body 10 to the first interface 20. The insulating member 30 encapsulates the end of the first interface 20 near the cable body and the portion of the circuit board 21 exposed outside the housing 22 and connected to the wire 12, thereby connecting the housing 22, circuit board 21, and cable body 10 into one. The insulating member 30 also improves the overall rigidity and strength of the plug-in end of the data cable 100, effectively preventing the circuit board 21 and the second portion 122 of the wire 12 from breaking, and ensuring insulation of the circuit board 21.

[0034] The data cable 100 provided by this utility model, please refer to Figure 1 、 Figure 3 and Figure 4 The wrapping layer 11, the first interface 20, and the insulating member 30 are all flat. The flat shape of the wrapping layer 11 also results in a flat overall shape for the wire body 10. The flat shape of the wire body 10 facilitates storage and winding, reducing the thickness of the wire body 10. Simultaneously, the overall shape of the first interface 20 and the insulating member 30 are also flat, effectively reducing the thickness of the first interface 20. The wire body 10 and insulating member 30 of the data cable 100 are both compatible with the flat first interface 20, effectively reducing the thickness and overall volume of the data cable 100, resulting in a simple, compact, and easy-to-use structure.

[0035] It should be noted that the aforementioned multiple conductors 12 refer to two or more conductors 12. In addition, the drawings of this application do not fully illustrate the conductive structure on the circuit board 21. The circuit board 21 has structures such as probes that implement its functions. The structure of the circuit board 21 can refer to the existing technology and will not be described in detail in this embodiment.

[0036] In some embodiments, the insulating member 30 can be a prefabricated structural member that is assembled by gluing or other means. In some embodiments, the insulating member 30 is an injection-molded insulating member 30 that is integrally formed on the wire body 10 and the first interface 20 through an injection molding process after the wire 12 is welded to the circuit board 21 of the first interface 20. After the injection molding is completed, the insulating member 30 directly covers the wire body 10 and the first interface 20, and exposes the portion of the first interface 20 that is plugged into and docked with the device, so that the circuit board 21, the housing 22, the solder joints between the wire 12 and the circuit board 21, and the wire body 10 are integrally formed, and the circuit board 21 is ensured to be insulated from the outside.

[0037] In some embodiments, in order to further optimize the layout and connection scheme of the wire body 10 and the first interface 20, please refer to Figure 2 and Figure 3 Since the wire body 10 is a flexible structure, its positional relationship with the first interface 20 is different in different postures. Therefore, for the sake of convenience of description, the state in which the first portion 121 is parallel to the circuit board 21 is used as a reference. At this time, when the wrapping layer 11 is parallel to the circuit board 21, or in other words, when the wrapping layer 11 is parallel to the circuit board 21, the first portion 121 of the wire 12 is parallel to the circuit board 21, so that the wrapping layer 11, the first portion 121 and the circuit board 21 are arranged in a mutually parallel posture, which can further reduce the thickness of the wire body 10. At the same time, along the thickness direction of the wire body 10, the multiple first portions 121 corresponding to the multiple wires 12 are distributed in one or two planes parallel to the circuit board 21. By arranging the multiple wires 12 in at most two planes in the thickness direction of the wire body 10, the thickness of the wire body 10 can be effectively controlled.

[0038] In some embodiments, in the thickness direction of the wire body 10, multiple first parts 121 can be distributed simultaneously in a plane parallel to the circuit board 21, and the multiple first parts 121 are spaced apart along the width direction of the wire body 10 to avoid the first parts 121 from overlapping in the thickness direction, which can significantly reduce the thickness of the wire body 10.

[0039] In some embodiments, in order to protect the insulating member 30, to avoid exposure of the internal structure caused by wear or damage of the insulating member 30, and to improve the safety performance of the data cable 100, please refer to Figure 5 and Figure 6 The outer circumference of the insulating member 30 is provided with a limiting step 31, which is arranged around the circumference of the insulating member 30. The data cable 100 also includes a protective cover 40, which is sleeved over the insulating member 30 and positioned by the limiting step 31. The protective cover 40 covers the area between the plug-in portion of the first interface 20 and the wrapping layer 11, effectively protecting the electrical connection structure between the first interface 20 and the cable body 10. At the same time, the protective cover 40 can be quickly replaced for maintenance.

[0040] In some embodiments, please refer to Figure 1 and Figure 5 The limiting step 31 is located at one end of the insulating part 30 close to the wrapping layer 11, and the end of the protective cover 40 away from the limiting step 31 has a smooth closing portion 41. The closing portion 41 completely wraps the end of the insulating part 30 away from the limiting step 31 to avoid exposure of the end of the insulating part 30 away from the limiting step 31, thereby protecting the insulating part 30.

[0041] In some embodiments, please refer to Figure 5 and Figure 7The protective cover 40 may be a metal protective cover 40 , so that the structural strength of the protective cover 40 is improved by the metal material, so that the protective cover 40 will not be easily damaged.

[0042] In some embodiments, the protective cover 40 can be a flat hollow sleeve with a wall thickness of 0.1mm-1mm. By controlling the wall thickness of the protective cover 40 to 0.1mm-1mm, the overall size of the plug end of the data cable 100 can be further controlled for ease of use.

[0043] In some embodiments, the technical feature that "the protective cover 40 can be a metal protective cover 40" and the technical feature that "the protective cover 40 can be a flat hollow sleeve, and the wall thickness of the protective cover 40 is 0.1mm-1mm" can exist at the same time.

[0044] In order to install and fix the protective cover 40 , glue or the like may be applied to the outer surface of the insulating member 30 and / or the inner surface of the protective cover 40 before assembly to improve the connection strength between the protective cover 40 and the insulating member 30 .

[0045] In some embodiments, please refer to Figure 1 and Figure 5 The shell 22 includes an insertion section 221, a transition section 222 and a cut-off section 223. The insertion section 221 is used to cooperate with the plug interface of the device. The cut-off section 223 is closer to the wrapping layer 11 than the insertion section 221. The outer surface of the cut-off section 223 protrudes outward than the outer surface of the insertion section 221. The transition section 222 smoothly connects the insertion section 221 and the cut-off section 223. The opening size of the cut-off section 223 is larger than the size of the insertion section 221, so that there is sufficient circumferential sleeve fitting clearance between the circuit board 21 and the cut-off section 223, which is convenient for the assembly of the shell 22 and the circuit board 21. The total length of the cut-off section 223 and the transition section 222 does not exceed the length of the insertion section 221, and sufficient operating space is reserved for the welding work of the circuit board 21 and the second part 122 of the wire 12, so as to ensure that there is sufficient contact area between the insulating member 30, the shell 22 and the circuit board 21, so as to ensure the connection strength between the insulating member 30, the shell 22 and the circuit board 21.

[0046] In some embodiments, please refer to Figure 5 The total length of the cut-off section 223 and the transition section 222 does not exceed 1 / 2 of the length of the insertion section 221, so that the length of the circuit board 21 extending out of the cut-off section 223 can be relatively longer, further improving the connection strength between the insulating member 30, the shell 22, and the circuit board 21.

[0047] In some embodiments, please refer to Figure 1 and Figure 5The shell 22 is a flat tube, and the end of the circuit board 21 away from the wire body 10 is accommodated in the shell 22. The end of the shell 22 away from the wire body 10 has a smooth necked portion 224. The necked portion 224 can play an auxiliary positioning role during the assembly process of the shell 22 and the circuit board 21. At the same time, the smooth necked portion 224 can effectively avoid scratching the user.

[0048] This embodiment does not limit the specific type of the first interface 20. The first interface 20 can be a type-c interface, a lightning interface, a micro-b interface, or other interfaces in the prior art.

[0049] In some embodiments, please refer to Figure 1 and Figure 2 The data cable 100 further includes a second interface 50, and the first interface 20 and the second interface 50 are electrically connected to opposite ends of the cable body 10. The second interface 50 can be the same as or different from the first interface 20, as long as the data transmission function is achieved. In some embodiments, the first interface 20 and the second interface 50 can be different types of interfaces, but the components and the connection relationship between the components can be the same.

[0050] The preparation method and process of the data cable 100 provided by the present invention are as follows:

[0051] 1. Solder the second portion 122 of the wire body 10 to the assembled circuit board 21 of the first interface 20 .

[0052] 2. Place the welded wire body 10 and the first interface 20 into an injection mold, and form an insulating member 30 by injection molding, so that the insulating member 30 covers the wire body 10 , the circuit board 21 and the housing 22 .

[0053] 3. Put the protective cover 40 on the insulating member 30.

[0054] In summary, in the data cable 100 provided by the present invention, the conductor 12 extends out of the second portion 122 of the wrapping layer 11 and is electrically connected and fixed to the circuit board 21, forming a conductive transmission route. The wire body 10, the housing 22, and the circuit board 21 are directly and stably connected through the insulating member 30. The housing 22 wraps around part of the circuit board 21 structure, while the insulating member 30 wraps around the ends of the wire body 10 and the first interface 20 that are close to each other. Under the joint action of the housing 22 and the insulating member 30, the first interface 20 and the connection portion of the wire body 10 are encapsulated and fixed. The outer shape of the wrapping layer 11 is flat, so the overall shape of the wire body 10 is also flat. The flat wire body 10 is easy to store and can reduce the size of the wire body 10 in the thickness direction. At the same time, the overall shape of the first interface 20 and the insulating member 30 is also flat, which can effectively reduce the size of the first interface 20 in the thickness direction. The wire body 10 and the insulating member 30 of the data cable 100 are both adapted to the flat first interface 20, effectively reducing the size of the data cable 100 in the thickness direction and the overall volume, and having the beneficial effects of compact structure, easy use, simple processing technology and low cost.

[0055] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
