Description

Technical Field

[0001] The utility model relates to the technical field of USB data transmission cables, in particular to an in-mold braided data cable. Background Art

[0002] USB is the most widely used external bus standard in the PC industry, regulating the connection and communication between computers and external devices. The USB interface supports plug-and-play and hot-swapping capabilities. With the rapid development of computer hardware and related electronic devices, the use of USB has increased the speed of data transmission between external devices. USB data cables are used to connect and communicate between computers and external devices, as well as charging mobile phones and connecting to external data. In other words, they are used for both data transmission and charging.

[0003] USB Type-C is a USB interface standard that is smaller than Type-A and Type-B. It can be used in both PCs (host devices) and external devices (slave devices, such as mobile phones).

[0004] With the development of USB Type-C, mobile phones and other electronic devices now essentially all use data cables with this interface terminal for charging or data transmission. For ease of use, data cables are typically provided in relatively long lengths. However, during daily use, cables often bend and may even bend slightly, especially when users use their phones while charging. Since the plug-in terminal is inserted into an external device and is fixed, the bending of the cable body and the plug-in terminal can create a bending conflict, which can easily cause the connection between the plug-in terminal and the cable body to break, shortening the service life of the data cable.

[0005] Therefore, there is a need to improve the data cable so that it can be easily bent, thereby extending its service life. Utility Model Content

[0006] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0007] The utility model provides an in-mold braided data cable, comprising a cable body and plug-in terminals located at both ends of the cable body, wherein the cable body is electrically connected to the plug-in terminals at both ends respectively, the outer wall of the plug-in terminals is provided with a metal shell, and an auxiliary part is provided between the cable body and the metal shell, wherein the auxiliary part forms a fixed connection between the metal shell and the cable body respectively, and the auxiliary part is manufactured by adopting an injection mold and an in-mold injection molding process.

[0008] As a further solution of the present invention: the auxiliary component is made of a plastic material with a certain elasticity.

[0009] As a further solution of the present invention: a plurality of grooves are provided on the outer periphery of the auxiliary component, so that a convex strip protruding from the bottom of the groove is formed between two grooves.

[0010] As a further solution of the present invention: a certain inclination angle is formed between the convex strip and the axial direction of the auxiliary component.

[0011] As a further solution of the present invention: the inclination angle is set to 30 degrees to 65 degrees.

[0012] As a further solution of the present invention: a countersink of a certain depth is provided at the bottom of the groove, the countersink being used to reduce the thickness of the auxiliary component and making it easier to bend. The countersink is provided as an elongated strip and extends a certain length along the bottom of the groove.

[0013] As a further solution of the present invention: the depth of the countersunk hole is smaller than the distance between the bottom of the groove and the outer wall of the cable body.

[0014] As a further solution of the present invention: a plurality of metal wires are provided inside the cable body, and an insulating layer is provided on the outer periphery of the metal wires to insulate the metal wires.

[0015] As a further solution of the present invention: the multiple metal wires are in contact with each other and are located at the center of the cable body. An outer sheath is provided on the outer periphery thereof, and the outer sheath is used to protect the multiple metal wires.

[0016] As a further solution of the present invention: the outer periphery of the outer sheath is provided with a braided mesh, which is woven with a wear-resistant material, thereby forming a protective effect on the periphery of the cable body.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. By installing auxiliary parts between the cable body and the plug-in terminal, the bending performance is improved, making it easier to bend to a certain angle, thereby extending the service life of the data cable. In addition, the auxiliary parts are made using an in-mold injection molding process and are made of a plastic material with a certain elasticity. This can not only make the connection between the cable body and the plug-in terminal more stable, but also provide better bending performance, thereby improving the service life of the entire cable.

[0019] 2. Grooves can also be provided on the periphery of the auxiliary component, and convex strips can be formed, so as to increase the anti-slip property and reduce the thickness of the auxiliary component, making it easier to bend and preventing it from breaking during long-term use.

[0020] 3. A countersink can also be provided at the bottom of the groove to further reduce the thickness of the auxiliary component, thereby improving its bending performance, preventing breakage, and increasing its service life.

[0021] 4. A braided mesh is also set on the outer periphery of the cable body to strengthen the cable body. This can not only prevent the internal metal wire from breaking, but also enhance its anti-tensile performance, further extending the service life of the data cable.

[0022] Therefore, through the above-mentioned improvements, the present invention can provide an in-mold braided data cable, which has improved bending performance, prevents it from breaking during long-term use, and thus extends its service life.

[0031] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1 to 4 In an embodiment of the present invention, an in-mold braided data cable includes a cable body 10 and plug-in terminals 20 located at both ends of the cable body 10. The cable body 10 is electrically connected to the plug-in terminals 20 at both ends. A metal shell 21 is provided on the outer wall of one end of the plug-in terminal 20. An auxiliary component 30 is provided between the cable body 10 and the metal shell 21. The auxiliary component 30 forms a fixed connection between the metal shell 21 and the cable body 10. The auxiliary component 30 is manufactured using an injection mold and an in-mold injection molding process. The auxiliary component 30 is made of a plastic material with a certain degree of elasticity.

[0033] Specifically, statistics show that most existing data cables are damaged at the connection between the cable body 10 and the plug-in terminal 20, as this connection is located between the relatively flexible cable body 10 and the relatively rigid plug-in terminal 20. In actual use, data cables are typically used on different devices and in different locations. For ease of use, data cables typically have a relatively long cable body 10. During use, few people tend to keep the cable body 10 neatly arranged; they simply bend it randomly, as long as it works properly.

[0034] Secondly, during normal bending, since the plug-in terminal 20 is often plugged into and unplugged from other devices, it forms a relatively stable fixed connection, while the cable body 10 is relatively flexible. During the pulling and bending process, the bending force of the cable body 10 is essentially at the connection position where the auxiliary component 30 is located. Therefore, optimizing the position of the auxiliary component 30 and extending its service life is closely related to the service life of the entire data cable.

[0035] Therefore, the present invention uses a plastic material with a certain elasticity to manufacture the auxiliary component 30, and utilizes an in-mold injection molding process to strengthen the connection between the auxiliary component 30, the plug-in terminal 20, and the cable body 10, thereby increasing the service life of the auxiliary component 30 and the service life of the entire data cable. The entire plug-in terminal 20 can be manufactured using the corresponding metal terminal 22 and metal housing 21 of existing products. It is understood that the metal terminal 22 is also equipped with corresponding insulating materials and corresponding metal conductive clips inside, so that it can transmit data or power.

[0036] like Figure 2 and Figure 3 As shown, preferably, a plurality of grooves 31 are provided on the outer periphery of the auxiliary member 30 , so that a convex strip 32 protruding from the bottom of the groove 31 is formed between two grooves 31 .

[0037] Specifically, the groove 31 can reduce the thickness of the auxiliary member 30, making it easier to bend, thereby improving the bending performance between the cable body 10 and the plug terminal 20 and preventing the portion between the cable body 10 and the plug terminal 20 from breaking during use. The ridge 32 also provides an anti-slip effect, allowing the user to maintain a certain grip on the auxiliary member 30 while plugging or unplugging the plug terminal 20, thereby enhancing its friction with the plug terminal 20 and preventing slipping.

[0038] like Figure 3 As shown, preferably, a certain inclination angle is formed between the convex strip 32 and the axial direction of the auxiliary member 30. The inclination angle is set to 45 degrees to 75 degrees, preferably 67 degrees.

[0039] Specifically, the primary function of the ridges 32 is to increase friction. While friction is maximized when the angle is set directly to 90 degrees, this also places the ridges 32 in a parallel position with the radial direction of the auxiliary component 30, which can reduce the bending performance of the auxiliary component 30. In this parallel position, the bending occurs entirely within the groove 31. While this makes the groove 31 easier to bend, it also makes it more susceptible to breakage. However, when the ridges 32 are tilted at a certain angle, when the groove 31 bends to a certain degree, they will inevitably cause the ridges 32 to bend synchronously. Furthermore, the ridges 32 are thicker and less prone to breakage, further extending the life of the data cable.

[0040] Secondly, the grooves 31 and countersunk holes 33 are provided to enhance the bending performance of the auxiliary member 30. This means that even when the bending stress generated by the cable body 10 during bending is relatively small, the auxiliary member 30 can be bent to a certain extent, thereby reducing the risk of the cable body 10 breaking. When the bending stress is relatively large, to prevent the auxiliary member 30 from breaking, the ridges 32 inclined at a certain angle can be used to reinforce the auxiliary member 30, allowing it to withstand relatively large bending stress and thus making it less likely to break.

[0041] like Figure 2 and Figure 3 As shown, preferably, a countersink 33 of a certain depth is provided at the bottom of the groove 31 to reduce the thickness of the auxiliary member 30 and make it easier to bend. The countersink 33 is set as a long strip-shaped countersink 33 and extends a certain length along the bottom of the groove 31.

[0042] Specifically, since the data cable may bend to a certain extent during use, especially when the user is using a mobile phone while charging, it is more likely to bend. The plug-in terminal 20 is inserted into an external device and is in a fixed state, and a bending contradiction will be formed between the bent cable body 10 and the plug-in terminal 20, which may easily cause the connection between the plug-in terminal 20 and the cable body 10 to break. Therefore, a groove 31 can be provided at the position of the auxiliary part 30 to reduce the plastic material in the groove 31 area, so that the auxiliary part 30 can have a certain bending performance. In order to enhance this bending performance, a countersunk hole 33 can be provided at the bottom of the groove 31. The countersunk hole 33 is used to further reduce the thickness of the auxiliary part 30, making it easier to bend, thereby reducing the bending contradiction between the cable body 10 and the plug-in terminal 20 and extending the service life of the cable.

[0043] Furthermore, the depth of the countersunk hole 33 is less than the distance between the bottom of the groove 31 and the outer wall of the cable body 10. That is, the depth of the countersunk hole 33 does not penetrate the auxiliary member 30, leaving a certain thickness of elastic plastic between the outer wall of the cable body 10 and the bottom of the countersunk hole 33, thereby maintaining the surrounding and protection of the cable body 10.

[0044] like Figure 4 As shown, preferably, the cable body 10 is provided with a plurality of metal wires 11 inside, and the outer periphery of the metal wires 11 is provided with an insulating layer 12 to insulate the metal wires 11. The plurality of metal wires 11 are abutted against each other and are located at the center of the cable body 10. The outer periphery of the plurality of metal wires 11 is provided with an outer layer 13, which is used to protect the plurality of metal wires 11. The outer periphery of the outer layer 13 is provided with a braided mesh 14, which is woven from a wear-resistant material, thereby protecting the outer periphery of the cable body 10.

[0045] Specifically, to transmit data or power, the cable body 10 is further provided with a plurality of corresponding metal conductors 11. For insulation, an insulating layer 12 may be provided around each conductor, such as a PE insulating rubber sheath. To enhance the overall strength and bending performance of the data cable, an outer sheath 13 may be provided around the combined cable formed by the multiple conductors, such as a TPE plastic sheath. The braided mesh 14 may be woven from a wear-resistant fabric or injection-molded into a braided shape from a wear-resistant plastic material.

[0046] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced within the present invention.
