[0002] USB data cables are used for connection and communication between computers and external devices, and can also be used to charge mobile phones and connect to the outside world. In layman's terms, they are used to transfer data and charge. USB is a commonly used PC interface with only 4 wires, two power wires and two signal wires. USB is the most widely used external bus standard in the PC field, used to regulate the connection and communication between computers and external devices. The USB interface supports the plug-and-play and hot-swap functions of devices.

[0003] For example, a Chinese patent document with announcement number CN206225739U discloses a USB data circular transmission cable, including a USB interface, a connector, a tail plug and a data cable, wherein the data cable consists of a transparent PVC sleeve, PVC insulation, a first data cable, a second data cable, a third data cable and a fourth data cable, one end of the transparent PVC sleeve is fixedly connected to the tail plug, the transparent PVC sleeve is connected to the USB interface through the connector, PVC insulation is provided on the inner side of the transparent PVC sleeve, a first data cable is provided on the inner side of the PVC insulation, a second data cable is provided on one side of the first data cable, a third data cable is provided on one side of the second data cable, and a fourth data cable is provided on one side of the third data cable.

[0004] It simply puts the data cables in close contact with each other to form a whole cable. In actual use, due to different usage environments, or the need to carry it in a bag, etc., it is easy to cause the transmission line itself to bend and entangle, or even bend and knot, which can easily bend the wires inside the cable, resulting in poor contact or breakage, seriously affecting the service life of the cable. Utility Model Content

[0006] The utility model provides an anti-twisting long-life USB cable, comprising an extension cable with a certain length, one end of the extension cable is fixedly connected to a first interface, and the other end of the extension cable is fixedly connected to a second interface, the first interface and the second interface are electrically connected through an electric conductor in the extension cable; an anti-bending wire is also arranged inside the extension cable, and the anti-bending wire and the electric conductor are cross-wound to form a twisted cable.

[0007] As a further solution of the utility model: the outer peripheral sleeve of the twisted cable is provided with an insulating outer skin, and the insulating outer skin is made of TPE plastic material.

[0008] As a further solution of the utility model: the outer periphery of the insulating outer skin is also provided with a rainbow woven mesh, and the rainbow woven mesh is made of materials of various colors that are cross-woven to form a rainbow-like gradient color.

[0012] As a further solution of the utility model: the anti-bending thread is also provided with a fourth thread, and the fourth thread is arranged on the other side of the first hemp thread and the second hemp thread relative to the third thread.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By setting an anti-bending wire inside the extension cable and utilizing the anti-bending stress of the anti-bending wire, the problem of the cable being entangled itself can be avoided, and the cable can be further prevented from bending and tangling, thereby extending the service life of the USB cable.

[0015] 2. It is also possible to further provide anti-bending wires in two groups of different functional conductors, and cross-wind the anti-bending wires with the conductors to further enhance the anti-bending stress inside the cable and enhance its anti-winding effect.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0026] See also Figures 1 to 3In an embodiment of the utility model, a tangle-resistant and long-life USB cable comprises an extension cable 10 of a certain length, one end of the extension cable 10 is fixedly connected to a first interface 51, and the other end thereof is fixedly connected to a second interface 52, the first interface 51 and the second interface 52 are electrically connected through an electrical conductor 20 in the extension cable 10; an anti-bending wire 11 is also provided inside the extension cable 10, and the anti-bending wire 11 and the electrical conductor 20 are cross-wound with each other to form a twisted cable.

[0027] Specifically, in order to prevent the cable from getting entangled with itself and from bending and tangling, an anti-bending wire 11 can be set inside the cable, and the anti-bending wire 11 with a certain hardness and resilience can be used to generate anti-bending stress on the cable, so that the cable can return to its original shape, avoiding the problem of self-entanglement or bending and tangling, thereby extending the service life of the USB cable and optimizing the user's daily use experience. Among them, the first interface 51 can be set as a USB Type-A interface, and the second interface 52 can be set as a USB Type-C interface. Of course, it can also be set as other USB universal interfaces to expand its scope of use.

[0028] Secondly, the anti-bending wire 11 is preferably made of a material with a certain hardness and good resilience, preferably polypropylene, and can also be made of polycarbonate, acrylic, ABS, etc. The anti-bending wire 11 can be combined and arranged with the electric conductor 20 of the cable itself, preferably cross-wound to form a twisted cable, so as to further optimize the bending resistance of the cable. In this embodiment, the four electric conductors 20 inside the USB cable and the anti-bending wire 11 can be uniformly arranged to form a cross-wound shape with each other, thereby forming an integral twisted cable with strong bending resistance.

[0029] like Figure 2 As shown, preferably, the outer periphery of the twisted cable is provided with an insulating sheath 41, and the insulating sheath 41 is made of TPE plastic material.

[0030] Specifically, in order to protect the electric conductor 20 in the cable, an insulating sheath 41 can be provided to wrap the electric conductor 20 and provide a certain bending resistance. At the same time, the relatively soft TPE plastic material can also protect the electric conductor 20 to prevent damage to the wire, and can also improve the feel of the cable and optimize the user experience.

[0031] like Figure 2 As shown, preferably, the outer periphery of the insulating outer skin 41 is also covered with a rainbow woven mesh 42, and the rainbow woven mesh 42 is made of materials of various colors that are cross-woven to form a rainbow-like gradient color.

[0032] Specifically, in order to further enhance the bending resistance of the cable, a braided net can be set at the outermost part, and the stress generated by the cross-weaving of the braided net can be used to protect the cable from bending. The material of the braided net can be TPE plastic material, and the color is gradient red, green and blue. Through the setting of gradient color, the cable can present different color changes, beautify the appearance of the wire, and make the user feel happy.

[0033] In another embodiment, if Figure 2 and Figure 3 As shown, preferably, the electric conductor 20 in the extension cable 10 is provided with two data conductors 21 , and the anti-bending wire 11 is provided with a first wire 12 , and the first wire 12 and the two data conductors 21 are cross-entangled with each other to form a first hemp wire 31 .

[0034] Specifically, the two data conductors 21 used for transmitting data inside the USB cable can be cross-wound with the corresponding first wires 12 to form a twisted cable, which can not only improve its bending resistance, but also optimize the electromagnetic interference between the two electrical conductors 20 and optimize the data transmission performance.

[0035] In another embodiment, Figure 2 and Figure 3 As shown, preferably, the electric conductor 20 in the extension cable 10 is provided with two power conductors 22 , and the anti-bending wire 11 is provided with a second wire 13 , and the second wire 13 and the two power conductors 22 are cross-entangled with each other to form a second hemp rope 32 .

[0036] Specifically, the two power conductors 22 for transmitting electrical energy inside the USB cable can be cross-wound with the corresponding second wires 13 to form a twisted cable, thereby further improving the bending resistance of the cable and reducing electromagnetic interference between the two power conductors 20.

[0037] In another embodiment, Figure 2 and Figure 3 As shown, preferably, the anti-bending wire 11 is further provided with a third wire 14, and the third wire 14, the first hemp wire 31 and the second hemp wire 32 are arranged parallel to each other and are sheathed inside the insulating sheath 41 to form an integral cable.

[0038] Specifically, in order to further enhance the bending resistance of the cable, an additional bending-resistant wire 11 can be provided outside the twisted cable. For example, a third wire 14 can be provided, and the diameter of the third wire 14 is greater than that of the first wire 12 or the second wire 13. That is, a relatively thick bending-resistant wire 11 can be used, so that the third wire 14, the first hemp wire 31, and the second hemp wire 32 are arranged parallel to each other along their axes, slightly in a triangular shape, forming a cable cross-section that is roughly circular, so that the insulating outer skin 41 or the braided mesh can be better sleeved on the outer periphery of the circular cable. Making the cable circular can further improve its bending resistance and is also convenient for storage.

[0039] In addition, in order to further form a roughly circular appearance and at the same time further enhance the bending resistance of the cable, two relatively thick bending-resistant wires 11 can be provided. That is, a fourth wire 15 can also be provided, and the fourth wire 15 is arranged on the other side of the first hemp wire 31 and the second hemp wire 32 relative to the third wire 14. As Figure 3 described, the four wires can be arranged slightly in a square shape, thus forming a more plump circle, which is convenient for the insulating outer skin 41 or the braided mesh to be sleeved into a circular cable.

[0040] During use, the first interface 51 is respectively inserted into the corresponding USB female socket of the device, and the second interface 52 is inserted into the USB female socket of another device, thus forming a path for data transmission or power transmission. And the cable has a certain bending resistance, so during use, there is no need to worry about the extension cable 10 in the middle part getting entangled or bent and knotted by itself.

[0041] At the same time, during storage, the cable can also be stored and carried normally after ordinary storage, without worrying about the cable getting bent and entangled or bent and knotted, which is convenient for use and can also extend the service life of the cable.

[0042] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.
