Description

Technical Field

[0001] This invention relates to the field of data cables, and more specifically to a data cable and a data cable manufacturing process. Background Technology

[0002] With the widespread use of smartphones and other portable mobile electronic devices, data cables are increasingly used daily. As an electronic accessory used for charging and data transfer of electronic products, data cables are widely used in various portable electronic products. Generally speaking, data cables are mainly used to assist mobile phones or other digital products in exchanging data with computers or to charge mobile phones or other digital products via a USB connector connected to a computer, power bank, or charger.

[0003] Commonly used data cables in the prior art are generally complex in structure and large in size. At the same time, the manufacturing process may affect the quality and stability of the final product. Therefore, there is a technical problem in this field that is unable to properly balance the structural design and manufacturing process of data cables. Summary of the Invention

[0004] The main technical problem solved by this invention is how to provide a data cable that can take into account both the structural design and manufacturing process of the data cable, thereby improving the stability and reliability of the data cable product.

[0005] According to a first aspect, a data cable is provided, including a terminal shell, wires, a terminal assembly, and a first connector; the terminal shell is an integrally formed part; the wires include an insulating layer and multiple wire cores, the insulating layer is spaced apart from the terminal shell along the length direction of the data cable, and the multiple wire cores are wrapped inside the insulating layer and extend outside the insulating layer; along the length direction, the terminal assembly is sleeved with the terminal shell, the terminal assembly is entirely housed inside the terminal shell, the terminal assembly includes a connected terminal and a circuit board, one end of the circuit board is connected to the terminal and the other end is connected to the wire cores; the first connector connects the insulating layer and the terminal shell, and the first connector covers the portion of the wire cores located between the insulating layer and the terminal shell;

[0006] The terminal housing and the terminal assembly are provided with a positioning structure. The terminal assembly is fixed in the terminal housing by the positioning structure, or the terminal assembly is fixed in the terminal housing by the positioning structure and the first connector.

[0007] In one alternative embodiment, along the length direction, the first connector is located between the end face of the insulating layer and the terminal shell, and the two ends of the first connector abut against and connect to the end face of the insulating layer and the end face of the terminal shell, respectively.

[0008] In one alternative embodiment, the data cable further includes a second connector located within a terminal housing, the second connector covering at least a portion of the circuit board, and the second connector connecting the circuit board and the terminal housing.

[0009] In one alternative embodiment, the first connector and the second connector are integrally formed, and the first connector and the second connector are connected and smoothly transitioned.

[0010] In one alternative embodiment, the first connector is exposed between the insulating sheath and the terminal housing.

[0011] In one optional embodiment, the terminal shell is a through-hole shell with a smooth outer surface and a constricted end away from the wire. The inner cavity size of the constricted portion gradually decreases from the direction away from the wire. The positioning structure includes the constricted portion.

[0012] In one alternative embodiment, along the length direction, the terminal housing includes a connected insertion section and an extension section, the insertion section being for mating with a circuit terminal, and the length of the extension section being greater than or equal to the length of the insertion section.

[0013] In one alternative embodiment, the ratio of the length of the extension to the length of the insertion portion ranges from 1.1 to 2.5.

[0014] In one alternative embodiment, the first connector is an injection-molded component formed by an injection molding process; or the first connector is a gel component formed by a curing process.

[0015] According to the second aspect, a data cable manufacturing process is provided for producing the aforementioned data cable, the data cable manufacturing process comprising the following steps:

[0016] The portion of the wire extending beyond the insulation layer is welded and fixed to the circuit board in the prepared terminal assembly;

[0017] The terminal housing is fitted onto the circuit board and the terminal, and the relative position of the terminal housing and the circuit board is determined by the positioning structure so that the circuit board is completely placed inside the terminal housing, and the terminal housing and the insulating layer are spaced apart along the length direction;

[0018] The first connector is formed by injection molding or adhesive curing molding, and the first connector connects at least the insulating layer, the wire core and the terminal shell.

[0019] The overall structure of the data cable according to the above embodiment has been improved. This is reflected in the increased fit between the terminal assembly and the terminal shell along the length of the data cable. The terminal assembly is entirely housed within the terminal shell; that is, along the length of the data cable, neither of the two opposite end faces of the terminal assembly protrudes from the terminal shell. Furthermore, the terminal shell is a one-piece molded component with good rigidity. The terminal shell and terminal assembly constitute the plug-in interface of the data cable. The terminal shell significantly enhances the structural strength of the entire plug-in interface, making the connection between the terminal shell, the first connector, and the wire more stable. On the other hand, the data cable manufacturing process has been improved. First, the wire core is soldered to the circuit board of the terminal assembly. Then, the terminal shell is fitted onto the terminal assembly, and the relative position of the terminal shell and terminal assembly is determined by a positioning structure. At this point, the insulating layer is spaced apart from the terminal shell along the length. Then, the first connector is prepared and assembled. Under the action of the positioning structure and the first connector, the terminal shell, wire, and terminal assembly are connected as a whole, with their relative positions fixed. The terminal sleeve can protect the circuit board to a certain extent, reducing the probability of circuit structure displacement and connection failure on the circuit board, thereby improving product quality and stability.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0029] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0030] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0031] The applicant discovered that in existing data cables, the circuit board of the terminal assembly extends beyond the terminal sleeve and connects to the wire core. Connecting the terminal sleeve and the insulation layer inevitably requires passing through the exposed portion of the circuit board, often covering it. This poses a risk of damaging the circuit structure on the circuit board, potentially leading to quality issues in the final product. Furthermore, the connection between the terminal assembly and the wire has poor resistance to external forces. To address these problems, this application provides a data cable and a data cable manufacturing process, improving the data cable's structure and adapting the manufacturing process to make the data cable's structure more rational.

[0032] Firstly, please refer to Figures 1-3 This application provides a data cable 100, which includes a terminal shell 10, a conductor 20, a terminal assembly 30, and a first connector 40. The terminal shell 10 is a one-piece molded part; the conductor 20 includes an insulating layer 21 and a plurality of wire cores 22. Along the length direction of the conductor 20, the insulating layer 21 is spaced apart from the terminal shell 10, and the plurality of wire cores 22 are covered inside the insulating layer 21 and extend outside the insulating layer 21; along the length direction of the data cable 100, the terminal assembly 30 is sleeved with the terminal shell 10, and the terminal assembly 30 is entirely housed inside the terminal shell 10. The terminal assembly 30 includes a connected terminal 31 and a circuit board 32. One end of the circuit board 32 is connected to the terminal 31, and the other end is connected to the wire cores 22; the first connector 40 connects the insulating layer 21 and the terminal shell 10, and the first connector 40 covers the portion of the wire cores 22 located between the insulating layer 21 and the terminal shell 10. Wherein: a positioning structure is provided between the terminal housing 10 and the terminal assembly 30, and the terminal assembly 30 is fixed in the terminal housing 10 by the positioning structure, or the terminal assembly 30 is fixed in the terminal housing 10 by the positioning structure and the first connector 40.

[0033] This application improves the overall structure of the data cable 100 by increasing the mating dimensions of the terminal assembly 30 and the terminal shell 10 in the length direction. The terminal assembly 30 is entirely housed within the terminal shell 10, meaning that along the length of the data cable 100, the length of the terminal shell 10 is greater than the length of the terminal assembly 30. Neither of the two opposite end faces of the terminal assembly 30 is exposed relative to the terminal shell 10. The terminal shell 10 and the terminal assembly 30 constitute the plug-in interface of the data cable 100. Since the terminal shell 10 is a one-piece molded part, it has good rigidity. The terminal shell 10 significantly improves the structural strength of the entire plug-in interface, making the connection between the terminal shell 10, the first connector 40, and the wire 20 more stable, improving its resistance to deformation, eliminating the need for additional reinforcing structures, simplifying the structure of the data cable 100, and reducing production costs. The first connector 40 covers the wire core 22 located between the insulation layer 21 and the terminal shell 10, and fixes the insulation layer 21 and the terminal shell 10 together, meeting safety requirements. The area of ​​the circuit structure on the circuit board 32 is a certain distance away from the end face of the terminal housing 10. Therefore, when the first connector 40 connects the terminal housing 10 and the wire 20 into one unit, the influence of the first connector 40 on the effective structure on the circuit board 32 can be reduced to a certain extent through reasonable size and structural design, thereby effectively improving the functional stability of the terminal assembly 30.

[0034] It should be noted that the length direction of the conductor 20 is consistent with the length direction of the data line 100. The length direction can be understood as the length direction of the conductor 20 or the length direction of the data line 100. The aforementioned multiple wire cores 22 refer to two or more wire cores 22, which are integrated together by the insulating layer 21.

[0035] "Terminal assembly 30 is fixed inside terminal housing 10 by positioning structure" means that the positioning structure determines the limit position of insertion between terminal assembly 30 and terminal housing 10, while preventing terminal assembly 30 and terminal housing 10 from detaching from each other. At this time, the first connector 40 can be connected to or spaced apart from the circuit board 32. The connection includes fixed connection and contact connection. "Terminal assembly 30 is fixed inside terminal housing 10 by positioning structure and first connector 40" means that the positioning structure determines the limit position of insertion between terminal assembly 30 and terminal housing 10. The first connector 40 acts on terminal 31 to prevent terminal assembly 30 from detaching from terminal housing 10. At this time, the first connector 40 can simply abut against the end face of circuit board 32 away from terminal 31, or it can be directly connected and fixed to circuit board 32.

[0036] Secondly, other undescribed structures of the terminal assembly 30 and terminal housing 10 can be referenced from existing technologies and will not be elaborated upon in this embodiment. For example, the insulation scheme used between the terminal assembly 30 and terminal housing 10, which is not specifically described in this embodiment, can be found in [reference needed]. Figure 2 and Figure 6 The terminal assembly 30 also includes an insulating sleeve 33 that covers the terminal 31 and is positioned and connected to the terminal 31, and the insulating sleeve 33 achieves insulation between the terminal assembly 30 and the terminal housing 10; for example, the accompanying drawings of this application do not fully show the functional structures such as probes on the circuit board 32.

[0037] In addition, the wire core 22 usually has its own insulating outer layer. When designing the specific structure, it is also necessary to consider the insulation between the first connector 40 and the wire core 22 and the circuit board 32. The specific insulation scheme can be adapted to actual needs. For example, the first connector 40 can be directly an insulating component. This embodiment does not limit this.

[0038] There are various ways to connect the first connector 40 to the terminal housing 10 and the insulating layer 21. Taking the connection between the first connector 40 and the insulating layer 21 as an example, in some embodiments, the end of the first connector 40 near the insulating layer 21 can be sleeved on the outside of the insulating layer 21. In other embodiments, the first connector 40 and the insulating layer 21 can also be fixed by end-to-end connection. Similarly, there are various ways to connect the first connector 40 to the terminal housing 10. In some embodiments, the end of the first connector 40 near the terminal housing 10 can be sleeved on the outside of the terminal housing 10. In other embodiments, the first connector 40 and the terminal housing 10 can also be fixed by end-to-end connection.

[0039] In some embodiments, in order to effectively control the thickness dimension of the data line 100 while improving its performance and structural strength, please refer to... Figure 1 and Figure 2 Along the length direction, the first connector 40 is located between the end face of the insulating layer 21 and the terminal shell 10, and the two ends of the first connector 40 abut against the end face of the insulating layer 21 and the end face of the terminal shell 10 respectively, so that the thickness of the terminal shell 10 and the insulating layer 21 at their close ends will not be significantly increased.

[0040] To improve the user experience, in some embodiments, the outer surface of the first connector 40 is smoothly connected to both the outer surface of the insulating layer 21 and the outer surface of the terminal housing 10, so as to effectively reduce the probability of scratching the user.

[0041] In some embodiments, please refer to Figure 1 The first connector 40 is exposed between the insulating layer 21 and the terminal housing 10. In other words, the outer surface of the first connector 40 is not provided with any other protective sleeves, protective shells or other structures. When in use, the user can directly hold the first connector 40.

[0042] In some embodiments, to improve the positioning stability between the terminal assembly 30 and the terminal housing 10, please refer to... Figures 2-4 The data cable 100 also includes a second connector 50, which is an insulating component. The second connector 50 is located inside the terminal housing 10. The second connector 50 covers at least part of the circuit board 32 and connects the circuit board 32 and the terminal housing 10 to increase the connection area between the circuit board 32 and the terminal housing 10, thereby further improving the structural strength of the data cable 100.

[0043] In some embodiments, to facilitate production and simplify the structure of the data cable 100, please refer to [reference needed]. Figure 2 and Figure 3The first connector 40 and the second connector 50 are integrally formed, and the first connector 40 and the second connector 50 are connected and smoothly transitioned.

[0044] In some embodiments, the data cable 100 may further include a third connector, which is connected to the end of the first connector 40 facing the insulating layer 21, the third connector covers the insulating layer 21, and the third connector is integrally formed with the first connector 40.

[0045] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 7 The terminal housing 10 is a through-hole housing with a smooth outer surface. The end of the terminal housing 10 away from the wire 20 is a constriction portion 11. The inner cavity size of the constriction portion 11 gradually decreases from the direction away from the wire 20. The positioning structure includes the constriction portion 11. When the terminal housing 10 and the terminal assembly 30 are assembled, the constriction portion 11 gradually approaches the terminal assembly 30 and finally abuts against the terminal 31, defining the limit position of the connection between the terminal housing 10 and the terminal assembly 30. The outer surface of the constriction portion 11 is also smooth and the size gradually decreases. The constriction portion 11 can play an auxiliary positioning role during the assembly process. At the same time, the smooth constriction portion 11 can effectively prevent scratches to the user.

[0046] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 5 Along the length direction, the terminal housing 10 includes a connecting insertion section 12 and an extension section 13. The insertion section 12 is used to plug into the circuit terminal 31, and 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.

[0047] It should be noted that the length of the insertion segment 12 of the interface of the data cable 100 corresponds to the national standard length and other standard lengths. Each type of interface has a standard insertion segment 12 length, and the total length of the terminal shell 10 of a general interface will not exceed 1.5 times the length of the insertion segment 12.

[0048] This embodiment does not limit the specific type of the interface formed by the terminal assembly 30 and the terminal 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.

[0049] For example, taking a Type-C interface as an example, the length of the insertion segment 12 is 5.7mm, and the length of the extension segment 13 can be in the range of 5.7mm-30mm, such as 6mm, 6.5mm, 6.7mm, 22mm, 23mm, etc. Preferably, the length of the extension segment 13 can be in the range of 7mm-20mm, such as 7mm, 7.2mm, 7.5mm, 16mm, 16.5mm, 17mm, etc. Further, in some embodiments, the length of the extension segment 13 can be between 8mm-15mm, such as 8mm, 8.2mm, 9mm, 9.5mm, 10mm, 11mm, 12mm, 13mm, 14mm, 14.5mm, 15mm, etc.

[0050] In some embodiments, please refer to Figures 1-3 In order to balance the structural strength of the interface and the operability of the manufacturing 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.

[0051] The first connector 40 connects the insulating layer 21 and the terminal housing 10 in ways including but not limited to injection molding, curing, and bonding. For example, in some embodiments, the first connector 40 can be an injection-molded component formed on the terminal housing 10 and the wire 20 by an injection molding process; or in other embodiments, the first connector 40 can be an adhesive component formed on the terminal housing 10 and the wire 20 by a curing process. For example, a UV-cured adhesive can be selected.

[0052] In some embodiments, please refer to Figures 1-3 The insulating layer 21, terminal shell 10, terminal assembly 30, and connectors of the data cable 100 are all flat. Multiple wire cores 22 are spaced apart along the width of the conductor 20. The flat shape of the insulating layer 21 results in a flat overall shape for the conductor 20. This flat shape facilitates storage and winding, reducing the conductor's thickness. Furthermore, the staggered spacing of the multiple wire cores 22 prevents thickness overlap. By strategically positioning the wire cores 22, the overall thickness of the conductor 20 can be effectively controlled, resulting in a smaller overall size. The compatible insulating layer 21, terminal shell 10, terminal assembly 30, and connectors of this data cable 100 effectively reduce its thickness and overall volume, offering advantages such as simple structure, compact size, and ease of use.

[0053] In some embodiments, along the thickness direction of the conductor 20, the corresponding portions of the plurality of wire cores 22 wrapped in the insulating layer 21 are distributed in one or two planes parallel to the circuit board 32. By arranging the plurality of wire cores 22 in at most two planes in the thickness direction of the conductor 20, the thickness dimension of the conductor 20 can be effectively controlled.

[0054] In some embodiments, please refer to Figure 1 and Figure 2 Both ends of the wire 20 are connected to a terminal housing 10, a terminal assembly 30, and a first connector 40. In other words, a first interface 61 is formed at the first end of the wire 20, and a second interface 62 is formed at the second end of the wire 20. The first interface 61 and the second interface 62 can be the same or different, as long as the data transmission function can be realized. In some embodiments, the first interface 61 and the second interface 62 can also be different types of interfaces, but the components and the connection relationships between the components can be the same.

[0055] In some embodiments, to facilitate determining whether the insertion segment 12 of the terminal housing 10 is properly inserted into the mating device, please refer to... Figure 1 An observation groove 14 can be opened at the end position of the insertion section 12 corresponding to the terminal housing 10.

[0056] Secondly, based on the same inventive concept, this application also provides a manufacturing process for a data cable 100, which includes the following steps:

[0057] The portion of the wire core 22 extending beyond the insulation layer 21 is soldered and fixed to the circuit board 32 in the prepared terminal assembly 30. Please refer to [reference needed]. Figure 6 ;

[0058] The terminal housing 10 is fitted onto the circuit board 32 and the terminal 31, and the relative position of the terminal housing 31 and the circuit board 32 is determined by the positioning structure, so that the circuit board 32 is completely placed inside the terminal housing 10, and the terminal housing 10 is spaced apart from the insulating layer 21 along the length direction. Please refer to [reference needed]. Figure 7 ;

[0059] The first connector 40 is formed by injection molding or adhesive curing, and the first connector 40 connects at least the insulating layer 21, the wire core 22, and the terminal shell 10. Please refer to [reference needed]. Figure 1 .

[0060] In summary, the data cable 100 provided by the present invention differs structurally from existing data cables 100, and the corresponding manufacturing process of the data cable 100 also differs from existing processes. The terminal shell 10 houses the terminal 31 and terminal assembly 30 as a whole within the terminal shell 10, and the circuit board 32 is not exposed. The integrally formed terminal shell 10 enhances the structural strength, protects the circuit board 32, and reduces the impact on the solder joints between the circuit board 32 and the wire core 22 and the effective structure on the circuit board 32 during the production process, thereby improving the reliability and stability of the product.

[0061] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the principles of this invention.
