DETAILED DESCRIPTION

[0030] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can easily recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, this is to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0031] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0032] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0033] The applicant has found that the control board of the connecting terminal in the data cable in the prior art extends out of the shell and is connected to the cable. To connect the shell and the insulating layer, it is inevitable to pass through the exposed part of the control board, and often cover the exposed part of the control board, which will cause the risk of damaging the circuit structure on the control board, and then the final product may have quality problems. At the same time, the connection between the connecting terminal and the cable body has poor resistance to external forces. In order to solve the above problems, the present application provides a data cable and a data cable production and preparation process, which improves the structure of the data cable and makes adaptive improvements to the production and preparation process, so that the structure of the data cable is more reasonable.

[0034] First, please refer to Figure 1-Figure 4The present application provides a data cable 100, which includes a cable body 20, a shell 10, a connection terminal 30 and a fixing part 40. The cable body 20 includes an insulating layer 21 and a plurality of cables, the plurality of cables are coated in the insulating layer 21, one end of the cables extends out of the insulating layer 21, and the shell 10 is an integrally formed part; along the length direction of the data cable 100, the shell 10 is directly connected to the insulating layer 21, the fixing part 40 is arranged in the shell 10, and the fixing part 40 connects the shell 10 and the insulating layer 21. Along the length direction of the data cable 100, the connection terminal 30 is sleeved with the shell 10, and the connection terminal 30 is accommodated in the shell 10 as a whole. The connection terminal 30 includes a control board 32 and a plug-in terminal 31 for plugging and matching with a docking device, one end of the control board 32 is connected to the cable, and the other end is connected to the plug-in terminal 31. Wherein: a positioning structure is provided between the housing 10 and the connecting terminal 30 , and the connecting terminal 30 is fixed in the housing 10 through the positioning structure, or the connecting terminal 30 is fixed in the housing 10 through the positioning structure and the fixing member 40 .

[0035] The present application has improved the overall structure of the data line 100, which is reflected in the increase in the matching size of the connection terminal 30 and the shell 10 in the length direction, and the connection terminal 30 is accommodated in the shell 10 as a whole, that is, along the length direction of the data line 100, the length of the shell 10 is greater than the length of the connection terminal 30, and the two opposite end faces of the connection terminal 30 are not exposed relative to the shell 10. The shell 10 and the connection terminal 30 constitute the plug-in interface of the data line 100. The shell 10 is assembled last, so when the fixing part 40 is formed or assembled, there is no shielding and obstruction of the shell 10. Through reasonable size design and structural design, the influence of the fixing part 40 on the effective structure on the control board 32 can be reduced to a certain extent, thereby effectively improving the functional stability of the connection terminal 30. Along the length direction of the data line 100, the shell 10 is directly connected with the insulating layer 21, which can be understood as the shell 10 and the insulating layer 21 are not separated in the length direction, so that after the insulating layer 21 and the shell 10 are connected and fixed, the fixing part 40, the extended cable and the control board 32 are completely encapsulated in the shell, meeting the safety requirements. The fixing part 40 supports and positions the shell 10 inside the shell. Since the shell 10 is an integrally formed part and has good rigidity, the shell 10 and the plug-in terminal 31 are used together to plug and cooperate with the docking device. The shell 10 can significantly improve the structural strength of the entire plug-in interface, making the connection between the shell 10, the fixing part 40 and the cable body 20 more stable, improving the ability to resist deformation, eliminating additional reinforcement structures, simplifying the structure of the data cable 100, and reducing production costs.

[0036] It should be noted that the length direction of the cable body 20 is consistent with the length direction of the data line 100, and the length direction can be understood as the length direction of the cable body 20, or the length direction of the data line 100. The above-mentioned multiple cables refer to two or more cables, and the multiple cables are integrated together through the insulating layer 21.

[0037] “The connecting terminal 30 is fixed in the housing 10 by a positioning structure” means that the positioning structure determines the extreme position of the plug-in between the connecting terminal 30 and the housing 10, and prevents the connecting terminal 30 and the housing 10 from being separated from each other. At this time, the fixing member 40 and the control board 32 can be connected or separated, and the connection includes a fixed connection and a contact connection. “The connecting terminal 30 is fixed in the housing 10 by a positioning structure and a fixing member 40” means that the positioning structure determines the extreme position of the socket connection between the connecting terminal 30 and the housing 10, and the fixing member 40 acts on the housing 10 to prevent the connecting terminal 30 from being separated from the housing 10. At this time, the fixing member 40 can only abut the end face of the control board 32 away from the terminal, or it can be directly connected and fixed to the control board 32.

[0038] Secondly, other structures of the connecting terminal 30 and the housing 10 that are not described can refer to the prior art, and this embodiment will not be repeated. For example, the insulation solution between the connecting terminal 30 and the housing 10 that is not specifically described in this embodiment, please refer to Figure 2 and Figure 3 The connecting terminal 30 also includes an insulating sleeve 33 that is wrapped around the plug-in terminal 31 and positioned and connected to the plug-in terminal 31, and insulation between the connecting terminal 30 and the housing 10 is achieved by the insulating sleeve 33; for example, the drawings of the present application do not fully illustrate functional structures such as probes on the control board 32.

[0039] In addition, cables generally have their own insulating sheath. When designing the specific structure, it is also necessary to consider the insulation between the fixing part 40 and the cable and control board 32. The specific insulation scheme can be adaptively adjusted according to actual needs. For example, the fixing part 40 can be directly an insulating component, etc. This embodiment does not limit this.

[0040] There are many ways to connect the fixing member 40 to the insulating layer 21. In some embodiments, the end of the fixing member 40 close to the insulating layer 21 can be sleeved outside the insulating layer 21. In some other embodiments, the fixing member 40 and the insulating layer 21 can also be fixed by connecting the end faces to the end faces. The fixing scheme of the fixing member 40 and the insulating layer 21 includes but is not limited to any feasible method such as bonding, integral connection after curing molding, etc., and this application does not limit it.

[0041] In some embodiments, please refer to Figure 4 and Figure 5The outer shell 10 and the insulating layer 21 are sleeved together to facilitate production and reduce difficulty. The structural strength of the data line 100 can also be further improved through the sleeved portion of the outer shell 10 and the insulating layer 21.

[0042] The manner in which the fixing member 40 is connected and fixed to the housing 10 includes, but is not limited to, welding, bonding, clamping, and the like. For example, in some embodiments, the fixing member 40 is bonded to the housing 10, and the fixing member 40 is bonded to the insulating layer 21. In other words, during assembly, the fixing member 40 is sticky and fixes the housing 10 and the insulating layer 21. In other embodiments, the fixing member 40 may include a welding portion and an insulating portion covering the welding portion, the insulating portion being connected and fixed to the insulating layer 21, and the welding portion being welded to the housing 10. After welding, the appearance may be improved and insulation safety may be ensured by applying an insulating coating or by adding an insulating protective cover to the welding portion of the housing 10.

[0043] In some embodiments, the fixing member 40 may be made of a colloid that can be converted from a fluid state to a solid state, such as a fluid glue that can be cured after being heated, a UV glue, etc. The fixing member 40 is a colloid component formed on the housing 10 and the cable body 20 through a curing process, that is, the fixing member 40 itself has sufficient viscosity after being formed. Before the fixing member 40 is cooled and completely formed, the assembly of the housing 10 is completed, and injection molding can be eliminated, which reduces the difficulty and cost of production and is conducive to improving production efficiency.

[0044] In some embodiments, the fixing member 40 may also be an injection molded part, and the connection and fixation between the injection molded part and the housing 10 and the insulating layer 21 is achieved by coating the surface of the injection molded part with glue or adhesive having sufficient bonding strength.

[0045] In some embodiments, to further position the connection terminal 30, the insulating layer 21 and the housing 10, please refer to Figure 6 and Figure 7 The fixing member 40 is formed on the end surface of the insulating layer 21 close to the circuit board, the fixing member 40 covers the cable, and the fixing member 40 covers the end of the control board 32 welded to the cable, so as to improve the connection stability between the connecting terminal 30 and the housing 10 under the action of the positioning structure and the fixing member 40.

[0046] Since the shell 10 and the insulating layer 21 are directly connected, the shell 10 can provide sufficient structural strength. The fixing part 40 mainly plays the role of fixed connection and can provide sufficient connection strength. It does not need to have a high structural strength. It is different from the connecting components used to bear and ensure the connection strength in the prior art. On the basis that the shell 10 and the insulating layer 21 can provide sufficient structural strength, the distance between the control board 32 and the insulating layer 21 can be shortened as much as possible along the length direction, which is beneficial to extend the size of the shell 10 without significantly increasing the total length of the limited plug-in interface of the data cable 100.

[0047] In some embodiments, please refer to Figure 3-Figure 5 The outer shell 10 is a through-hole shell, the outer surface of the outer shell 10 is a smooth surface, the end of the outer shell 10 away from the cable body 20 is a closing portion 11, and the inner cavity size of the closing portion 11 gradually decreases from the direction of the outer shell 10 away from the cable body 20; the positioning structure includes the closing portion 11, and when the outer shell 10 and the connecting outer shell 10 are assembled, the closing portion 11 gradually approaches the connecting terminal 30, and finally the closing portion 11 abuts the terminal, defining the socket limit position of the outer shell 10 and the connecting terminal 30, the outer surface of the closing portion 11 is also smooth and the size gradually decreases, the closing portion 11 can play a role in auxiliary positioning during the assembly process, and the smooth closing portion 11 can effectively avoid scratching the user.

[0048] In some embodiments, please refer to Figure 2 Along the length direction, the housing 10 includes an insertion section 12 and an extension section 13 connected to each other. The insertion section 12 is used to be plugged into and matched with the circuit terminal. The length of the extension section 13 is greater than or equal to the length of the insertion section 12, so as to effectively balance the improvement of structural strength and the improvement of resistance to external forces.

[0049] It should be noted that the length of the insertion section 12 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 12, and the total length of the shell 10 of a general interface will not exceed 1.5 times the length of the insertion section 12.

[0050] This embodiment does not limit the specific type of the interface formed by the connecting terminal 30 and the housing 10. In some embodiments, the interface can be a type-c interface, a lightning interface, or a micro-b interface. In other embodiments, the interface can also be other interfaces in the prior art.

[0051] For example, taking the interface as a type-c interface, the length of the insertion section 12 is 5.7 mm, and the length of the extension section 13 can be within the range of 5.7 mm-30 mm, such as 6 mm, 6.5 mm, 6.7 mm, 22 mm, 23 mm, etc. In some embodiments, the length of the extension section 13 can be within the range of 15 mm-30 mm, such as 15.5 mm, 16 mm, 17 mm, 18 mm, 20 mm, 22 mm, 25 mm, 27 mm, 28 mm, etc. The extension section 13 is sleeved with the insulating layer 21, and the extension section 13 has sufficient length. By increasing the sleeve length of the extension section 13 and the insulating layer 21, the high strength characteristics of the extension section 13 can be utilized to protect the cable body 20. In some embodiments, the length of the extension section 13 can be between 8 mm and 15 mm, such as 8 mm, 8.2 mm, 9 mm, 9.5 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 14.5 mm, 15 mm, etc.

[0052] In some embodiments, please refer to Figure 1 and Figure 2 In order to take into account both the structural strength of the interface and the operability of the production process, the ratio of the length of the extension section 13 interface to the length of the insertion part is in the range of 1.1-2.5. For example, the length of the extension section 13 interface can be 1.1 times, 1.2 times, 1.5 times, 2 times or 2.5 times the length of the insertion part.

[0053] The present invention does not impose any specific limitation on the appearance of the housing 10 , and it can be adaptively adjusted according to requirements as long as its function can be achieved.

[0054] In some embodiments, please refer to Figure 1 and Figure 5 The cross-sectional shape of the outer surface of the extension section 13 is the same as the cross-sectional shape of the outer surface of the insertion section 12. The extension section 13 includes a fixed-size section and a variable-size section. The cross-sectional size of the outer surface of the fixed-size section is larger than the cross-sectional size of the outer surface of the insertion section 12. The variable-size section smoothly connects the outer surface of the fixed-size section and the outer surface of the insertion section 12, and the size of the variable-size section gradually increases from the insertion section 12 to the fixed-size section. In other words, the outer surface of the extension section 13 protrudes outward compared to the outer surface of the insertion section 12, so that the shell has obvious segmentation in appearance, which is convenient for users to observe and use.

[0055] For example, in some embodiments, the cross-sectional shape of the outer surface of the extension section 13 is the same as the cross-sectional shape of the outer surface of the insertion section 12, and the cross-sectional size of the outer surface of the extension section 13 is the same as the cross-sectional size of the outer surface of the insertion section 12, that is, the outer shell 10 is a fixed-size component at this time, and the outer surface sizes of various parts of the outer shell 10 remain consistent.

[0056] It should be noted that the above only limits the cross-sectional shape formed by the outer surface of the extension section 13 and the outer surface of the insertion section 12. The present invention does not limit the size relationship and change relationship between the shape and size of the inner cavity of the extension section 13 and the shape and size of the inner cavity of the insertion section 12. The inner cavity of the outer shell 10 can be designed according to actual needs.

[0057] In some embodiments, please refer to Figure 3 The insulating layer 21, the outer shell 10, the connecting terminal 30 and the connecting piece are all flat. Along the width direction of the cable body 20, multiple cables are arranged at intervals. The outer shape of the insulating layer 21 is flat, and the overall shape of the cable body 20 is also flat. The flat cable body 20 is easy to store and wind, and can reduce the size of the cable body 20 in the thickness direction. At the same time, since the multiple cables are staggered in the width direction of the cable body 20, the thickness of the multiple cables will not overlap in the thickness direction. By reasonably setting the distribution position of the cables, the overall thickness of the cable body 20 can be effectively controlled, which has the effect of reducing the size. The insulating layer 21, the outer shell 10, the connecting terminal 30 and the connecting piece of the data cable 100 are adapted to each other, which effectively reduces the size of the data cable 100 in the thickness direction and the overall volume, and has the advantages of simple structure, compact structure and convenient use.

[0058] In some embodiments, along the thickness direction of the cable body 20, the corresponding parts of multiple cables wrapped in the insulating layer 21 are distributed in one or two planes parallel to the control board 32. By arranging multiple cables in at most two planes in the thickness direction of the cable body 20, the thickness dimension of the cable body 20 can be effectively controlled.

[0059] In some embodiments, please refer to Figure 1 and Figure 2 , both ends of the cable body 20 are connected to the housing 10, the connection terminal 30 and the fixing member 40. In other words, a first interface 51 is formed at the first end of the cable body 20, and a second interface 52 is formed at the second end of the cable body 20. The first interface 51 and the second interface 52 can be the same or different, as long as the function of data transmission can be realized. In some embodiments, the first interface 51 and the second interface 52 can also be different types of interfaces, but the components and the connection relationship between the components can be the same.

[0060] In some embodiments, in order to facilitate the determination of whether the insertion section 12 of the housing 10 is properly plugged into the docking device, please refer to Figure 1-Figure 2 An observation slot 14 may be provided at the end position of the housing 10 corresponding to the insertion section 12 .

[0061] In a second aspect, based on the same inventive concept, the present application also provides a data line 100 production process for producing the above-mentioned data line 100, and the data line 100 production process includes the following steps:

[0062] The portion of the cable extending out of the insulating layer 21 is welded and fixed to the control board 32 in the prepared connection terminal 30. Please refer to Figure 6 ;

[0063] The fixing member 40 is formed on the insulating layer 21 by curing molding, and the fixing member 40 is bonded to the insulating layer 21. Please refer to Figure 7 ;

[0064] The housing 10 is mounted outside the control board 32 and the connection terminal 30, and the relative positions of the housing 10 and the control board 32 are determined by the positioning structure, and the housing 10 is directly connected to the insulating layer 21, and the housing 10 and the fixing member 40 are connected and fixed to the housing 10, and the connection terminal 30 is fixed in the housing 10 as a whole. Please refer to Figure 1 .

[0065] In summary, the present invention has at least the following beneficial effects:

[0066] On the one hand, the overall structure of the data cable 100 has been improved, which is reflected in the increase in the matching size between the connecting terminal 30 and the shell 10 in the length direction. The connecting terminal 30 is accommodated in the shell 10 as a whole, that is, along the length direction of the data cable 100, the two opposite end faces of the connecting terminal 30 do not extend out of the shell 10. The shell 10 and the connecting terminal 30 constitute the plug-in interface of the data cable 100. The shell 10 can significantly improve the structural strength of the entire plug-in interface, making the connection between the shell 10, the fixing part 40 and the cable body 20 more stable.

[0067] On the other hand, the production process has been improved. First, the cable is welded to the control board 32 of the connecting terminal 30, and then the fixing part 40 is molded and installed so that the fixing part 40 is at least connected to the insulating layer 21. Then, the shell 10 is mounted on the connecting terminal 30, and the shell 10 is in direct contact with the insulating layer 21. Under the action of the positioning structure and the fixing part 40, the shell 10, the cable body 20 and the connecting terminal 30 are connected as a whole and the relative positions are fixed. The shell 10 can protect the control board 32 to a certain extent, reduce the probability of displacement of the circuit structure on the control board 32 and connection failure, and thus improve the quality and stability of the product.
