DETAILED DESCRIPTION

Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods.

For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0029] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0030] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0031] The present application provides a data cable, including a wire, a first interface and an insulating member, which is used to solve the technical problems of the data cable plug-in end having a complex structure, large size and inconvenient use in the prior art. The data cable has the advantages of a compact structure, easy use and high structural strength.

[0032] Please refer to Figure 1 and Figure 8The first interface 20 includes a circuit board 21, a terminal 23 and a shell 22. The circuit board 21 includes a body 211 and a welding portion 212 for welding. Along the length direction, the welding portion 212 is provided at one end of the body 211 close to the wire 10, and the terminal 23 is provided at one end of the body 211 facing away from the wire 10; the shell 22 is an integrally formed part, the circuit board 21 and the shell 22 are sleeved, the terminal 23 and the body 211 are located in the shell 22, and the welding portion 212 is exposed outside the shell 22; the wire 10 is welded and fixed to the welding portion 212; the insulating member 30 at least covers the welding portion 212 and is connected to the circuit board 21, the wire 10 and the shell 22.

[0033] According to the data cable 100 of the above embodiment, the wire 10 is electrically connected and fixed to the circuit board 21 to form a conductive transmission route. The wire 10, the shell 22 and the circuit board 21 are directly and stably and fixedly connected through the insulating member 30. The electrically connected part of the first interface 20 and the wire 10 is encapsulated to achieve insulation between the data cable 100 and the outside, ensuring safe use. Compared with the prior art, an integrated shell 22 is adopted, and the length of the shell 22 is increased. The shell 22 not only covers the terminal 23, but also covers the main body 211 of the circuit board 21, with only the welding part 212 exposed from the shell 22 and welded and fixed to the wire 10. On the one hand, the length of the shell 22 is extended, and the structural strength of the shell 22 itself is relatively high, which can effectively improve the overall rigidity and structural strength of the first interface 20 and improve the anti-deformation ability, and can eliminate additional reinforcement structures, simplify the structure of the first interface 20, and reduce production costs; on the other hand, the expansion of the length of the shell 22 is convenient for manual gripping, welding and other operations during production and assembly, and can also increase the connection area and connection strength between the shell 22, the insulating part 30 and the circuit board 21 to a certain extent, which is beneficial to extending the service life of the data cable 100.

[0034] In some embodiments, please refer to Figure 3 and Figure 5 In order to better improve the structural strength and external force resistance of the first interface 20, the shell 22 includes an insertion section 221 and an extension section 222 connected along the length direction. The insertion section 221 is used to mate with the circuit terminal. The terminal 23 is located in the insertion section 221, the welding portion 212 extends outside the extension section 222, the body 211 is located in the extension section 222, and the extension section 222 is greater than or equal to the length of the insertion section 221.

[0035] It should be noted that the length of the insertion section 221 of the interface of the data cable 100 corresponds to a standard length such as the national standard length. Each type of interface has a standard length of the insertion section 221, and the total length of the shell 22 of a general interface will not exceed 1.5 times the length of the insertion section 221. Therefore, compared with the prior art, the present application increases the length of the shell 22 without changing the design scheme of the circuit board 21 extending out of the shell 22, thereby achieving the technical effect of directly improving the overall structural strength of the first interface 20 through the extension section 222 without changing the original manufacturing process. At the same time, the insulating part 30 plays a role in assisting in improving the overall stiffness and strength of the plug-in end of the data cable 100, which can effectively prevent the connection between the circuit board 21 and the wire 10 from breaking and ensure the insulation of the circuit board 21.

[0036] This embodiment does not limit the specific type of the first interface 20. In some embodiments, the first interface 20 can be a type-c interface, a lightning interface, or a micro-b interface. In other embodiments, the first interface 20 can also be other interfaces in the prior art.

[0037] For example, taking the first interface as a type-c interface, the length of the insertion section is 5.7mm, and the length of the extension section can be in the range of 5mm-10mm, such as 5.2mm, 5.5mm, 6mm, 6.7mm, 7mm, 7.2mm, 7.5mm, 8mm, 8.2mm or 9mm, etc.

[0038] In some embodiments, please refer to Figure 4 and Figure 5 In order to take into account both the structural strength of the first interface 20 and the operability of the production process, the ratio of the length of the extension section 222 to the length of the insertion portion is in the range of 1-1.5. For example, the length of the extension section 222 can be 1.1 times, 1.2 times, 1.4 times or 1.5 times the length of the insertion portion. In this way, the high strength characteristics of the shell 22 can be utilized to significantly increase the connection area and connection strength between the shell 22, the insulating member 30 and the circuit board 21 without significantly increasing the length of the first interface 20, thereby effectively improving the anti-fracture ability of the connection part between the circuit board 21 and the wire 10.

[0039] The present application does not impose any specific limitation on the shape of the housing 22 , and it can be adaptively adjusted according to needs, as long as it can meet the function of the first interface 20 .

[0040] For example, in some embodiments, please refer to Figures 8-10The cross-sectional shape of the outer surface of the extension section 222 is the same as the cross-sectional shape of the outer surface of the insertion section 221. The extension section 222 may include a fixed-size section 223 and a variable-size section 224. The cross-sectional size of the outer surface of the fixed-size section 223 is larger than the cross-sectional size of the outer surface of the insertion section 221. The variable-size section 224 smoothly connects the outer surface of the fixed-size section 223 to the outer surface of the insertion section 221, and the size of the outer surface of the variable-size section 224 gradually increases from the insertion section 221 to the fixed-size section 223. In other words, the outer surface of the extension section 222 protrudes outward compared to the outer surface of the insertion section 221, so that the first interface 20 can have obvious segmentation in appearance, which is convenient for users to observe and use.

[0041] For example, in some embodiments, please refer to Figure 2-Figure 4 The cross-sectional shape of the outer surface of the extension section 222 is the same as the cross-sectional shape of the outer surface of the insertion section 221, and the cross-sectional dimensions of the outer surface of the extension section 222 are the same as the cross-sectional dimensions of the outer surface of the insertion section 221, that is, the shell 22 at this time is a fixed-size component, and the outer surface dimensions of various parts of the shell 22 are consistent.

[0042] It should be noted that the above only defines the cross-sectional shape formed by the outer surface of the extension section 222 and the outer surface of the insertion section 221. The present application does not define the size relationship and variation relationship between the shape and size of the inner cavity of the extension section 222 and the shape and size of the inner cavity of the insertion section 221. The inner cavity of the shell 22 can be designed according to actual needs.

[0043] In some embodiments, please refer to Figure 2 The wire 10 includes a wrapping layer 11 and a plurality of conductive wires 12. Along the length of the wire 10, the conductive wires 12 include a first portion 121 and a second portion 122. The first portion 121 is encased within the wrapping layer 11, while the second portion 122 extends outside the wrapping layer 11 and connects to the soldering portion 212. Along the length of the data cable 100, the wrapping layer 11 and the circuit board 21 are spaced apart to integrate the plurality of conductive wires 12 together through the wrapping layer 11. The conductive wires 12 are used for external electrical connection. The insulating member 30 includes a main body section 32 exposed between the housing 22 and the wrapping layer 11. The main body section 32 covers the protruding portions of the conductive wires 12 and the soldering portion 212, and the main body section 32 connects the wrapping layer 11 and the housing 22. The insulating member 30 is directly exposed at the interface end of the data cable 100. This increases the length of the housing 22, directly improving the structural strength of the first interface 20, eliminating the need for other insulating components or components for enhancing structural strength.

[0044] 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 main body 211 of the circuit board 21 also has probes, electronic devices, and other structures 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.

[0045] In some embodiments, please refer to Figure 2-Figure 4 The insulating member 30 also includes an extension section 31. The main body section 32 is integrally formed with the extension section 31. The ends of the main body section 32 abut and smoothly connect with the end faces of the wrapping layer 11 and the end faces of the housing 22, respectively. In other words, along the length of the data cable 100, the wrapping layer 11, the main body section 32, and the end faces of the housing 22 abut and connect in sequence, forming a single piece of the circuit board 21, the housing 22, the solder joints between the conductors 12 and the circuit board 21, and the wire 10, ensuring insulation of the circuit board 21 from the outside. The extension section 31 extends into the housing 22, covering a portion of the main body 211 and connecting the main body 211 and the housing 22, thereby increasing the effective connection area between the circuit board 21 and the housing 22. At the same time, it effectively controls the thickness of the insulating member 30, making the portion where the first interface 20 connects to the wire 10 thinner, more compact, and easier to use.

[0046] 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 can be an injection-molded insulating member 30 that is integrally formed with the wire 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. In some embodiments, after the injection molding is completed, the insulating member 30 can also directly cover the wrapping layer 11 and the extension section 222, and expose 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 10 are integrally formed, and the circuit board 21 is ensured to be insulated from the outside.

[0047] In other embodiments, the insulating member 30 may also be a cured adhesive member formed by curing UV glue, or a connecting member formed by other feasible methods other than injection molding and curing.

[0048] In some embodiments, please refer to Figure 6 and Figure 7 The first interface 20 and the insulating member 30 are both flat, and the insulating member 30 is adapted to the flat first interface 20 in appearance, which can effectively reduce the size of the first interface 20 in the thickness direction, thereby effectively reducing the size of the data line 100 in the thickness direction and the overall volume.

[0049] In some embodiments, please refer to Figure 1 and Figure 8The wrapping layer 11 is flat, and multiple conductors 12 are arranged at intervals along the width direction of the wire 10. The multiple conductors 12 are staggered with each other in the width direction of the wire 10, so that the multiple conductors 12 will not overlap in thickness direction. By reasonably setting the distribution position of the conductors 12, the overall thickness of the wire 10 can be effectively controlled, thereby reducing the size.

[0050] In some embodiments, please refer to Figures 1-4 、 Figure 6-Figure 8 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 10. The flat shape of the wire 10 facilitates storage and winding, reducing the thickness of the wire 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 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. This provides the advantages of a simple and compact structure and ease of use.

[0051] In some embodiments, in order to further optimize the layout and connection scheme of the wire 10 and the first interface 20, please refer to Figure 2 、 Figure 7 and Figure 9 Because the wire 10 is a flexible structure, its positional relationship with the first interface 20 varies in different postures. For ease of description, the state in which the first portion 121 is parallel to the circuit board 21 is used as a reference. In this state, 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. This allows the wrapping layer 11, the first portion 121, and the circuit board 21 to be arranged in a mutually parallel posture, which can further reduce the thickness of the wire 10. At the same time, along the thickness direction of the wire 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 along the thickness direction of the wire 10, the thickness of the wire 10 can be effectively controlled.

[0052] In some embodiments, in the thickness direction of the wire 10, multiple first parts 121 can be simultaneously distributed 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 10 to avoid the overlapping of the first parts 121 in the thickness direction, which can significantly reduce the thickness of the wire 10.

[0053] In an optional embodiment, the shell 22 is a flat tube, and the end of the circuit board 21 away from the wire 10 is accommodated in the insertion section 221. The end of the insertion section 221 away from the wire 10 has a smooth necking portion 225. The necking portion 225 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 necking portion 225 can effectively avoid scratching the user.

[0054] In some embodiments, please refer to Figure 1 and Figure 8 The data cable 100 further includes a second interface 40, and the first interface 20 and the second interface 40 are electrically connected to opposite ends of the wire 10. The second interface 40 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 40 can be different types of interfaces, but the components and the connection relationship between the components can be the same.

[0055] In some embodiments, in order to facilitate the judgment of whether the insertion section 221 of the first interface 20 is properly plugged into the docking device, please refer to Figure 1-Figure 5 , an observation slot 24 can be opened at the end position of the shell 22 corresponding to the insertion section 221.

[0056] The following describes the preparation method and process of the data cable 100 provided in this application, taking the insulating member 30 as an injection-molded insulating member as an example:

[0057] 1. Weld the second portion 122 of the wire 10 to the welding portion of the circuit board 21 of the first interface 20. The first interface 20 can be a prefabricated component that has been preassembled, or it can be assembled on-site at the production site.

[0058] 2. Place the welded wire 10 and the first interface 20 into an injection mold and form an insulating member 30 by injection molding. The insulating member 30 covers the circuit board 21 and the second portion 122 of the wire 12, and extends into the extension section 222 to connect the circuit board 21 and the housing 22. The insulating member 30 is respectively in contact with the end surfaces of the wrapping layer 11 and the extension section 222 that are close to each other, so as to connect the wire 10 and the first interface 20 as a whole.

[0059] In summary, the data cable 100 provided in this application increases the length of the housing 22 compared to the prior art, without changing the design of the circuit board 21 extending outside the housing 22. This achieves the goal of enclosing the body 211 of the circuit board 21 with only the soldering portion 212 of the circuit board 21 exposed outside the housing 22, without changing the original manufacturing process. This results in the technical effect of directly improving the overall structural strength of the first interface 20 through the higher strength of the housing 22. On the one hand, the increased length of the housing 22 facilitates manual handling and soldering operations during production and assembly, and also increases the connection area and connection strength between the housing 22, the insulating member 30, and the circuit board 21 to a certain extent, eliminating the need for additional reinforcement structures, simplifying the structure of the first interface 20, and helping to reduce production costs. At the same time, the insulating member 30 ensures a stable and fixed connection between the wire 10, the housing 22, and the circuit board 21. The insulating member 30 also helps to improve the overall rigidity and strength of the plug-in end of the data cable 100, effectively preventing breakage at the connection between the circuit board 21 and the wire 10, and ensuring the insulation of the circuit board 21.

[0060] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
