Abstract
Description
Technical Field
[0001] The utility model belongs to the field of data cables, and particularly relates to a data cable with high torsional rotation resistance. Background Art
[0002] With the increasing number of electronic devices and the popularization of Type-C interfaces, various electronic devices (such as mobile phones, laptops, chargers) need to be charged or transfer data at any time. The data cable includes head and tail connectors and the middle cable body. There is a transition from hard to flexible material between the connectors and the cable body. After twisting for a period of time or twisting significantly, the data cables on the market are prone to cracking at the SR, making the data cable unable to be used continuously. In order to meet the market demand, it is necessary to develop a data cable with high torsional resistance. Content of the Utility Model
[0003] The purpose of the utility model is to provide a durable data cable with high torsional rotation resistance.
[0004] To achieve the above purpose, the utility model provides a data cable with high torsional rotation resistance, including two interactive connectors and a cable body located between the two interactive connectors. A PCB wiring board that only supports the USB 2.0 protocol is arranged in the interactive connector. The cable body includes several inner core wires and an inner rubber layer that wraps all the inner core wires. An insulating layer is coated on the surface of each inner core wire, and the cross-sectional area of each inner core wire is 0.05 - 0.06 square millimeters.
[0005] As an improvement of the above solution, the area where several inner core wires are arranged does not exceed half of the radius length of the cable body.
[0006] As an improvement of the above solution, a corrugated tube made of nylon is sleeved outside the inner rubber layer, and an outer rubber layer is arranged outside the corrugated tube.
[0007] As an improvement of the above solution, the interactive connector includes a Type-C port at the head and a hard plastic shell at the tail. The hard plastic shell wraps at least 5 - 10 mm of the end of the cable body.
[0008] As an improvement of the above solution, the cross-section of the hard plastic shell is oblong, and the cable body is located at the center of the hard plastic shell.
[0009] The utility model has the following beneficial effects: The solution adopts an inner core wire with an extremely fine wire diameter, which can avoid tearing at the outermost side of the inner core wire when the wire body is bent, reducing stress fatigue. At the same time, the transmission power of the data cable is limited to the usb2.0 protocol, reducing the risk of melting of the extremely fine inner core wire. The combination of the above two not only meets the design indicators and satisfies the normal functions of the data cable, but also greatly increases the number of bending times of the data cable. The number of times of twisting from 720° to the left to 720° to the right is greater than 3000 times. BRIEF DESCRIPTION OF THE DRAWINGS

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0015] In the description of the present invention, the meaning of "several" is one or more, the meaning of "multiple" is two or more, and understandings such as "greater than", "less than", "exceeding" do not include the present number, and understandings such as "above", "below", "within" include the present number.

[0016] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "linkage", and "setting" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following will describe the embodiments of the present utility model based on its overall structure.
[0017] Referring to Figures 1 to 3 , the present utility model discloses a data cable with high torsional rotation, which includes two interaction connectors 11 and a cable body 12 located between the two interaction connectors 11. A PCB wiring board 22 that only supports the usb2.0 protocol is provided in the interaction connector 11. The cable body 12 includes a plurality of inner core wires 31 and an inner rubber layer 32 that wraps all the inner core wires 31. An insulating layer is coated on the surface of each inner core wire 31, and the cross-sectional area of each inner core wire 31 is 0.05 - 0.06 square millimeters.
[0018] The solution adopts inner core wires 31 with an extremely fine wire diameter, which can avoid the tearing of the outermost side of the inner core wires 31 when the cable body 12 is bent, and reduce stress fatigue; as Figure 3 shown, when magnifying the cable body 12, it can be found that the position with a larger diameter is stretched longer after bending. At the same time, the transmission power of the data cable is limited to the usb2.0 protocol, which reduces the risk of the extremely fine inner core wires 31 being fused and reduces the load on the inner core wires 31. The combination of the above two not only meets the design requirements and satisfies the normal functions of the data cable, but also greatly increases the number of bending times of the data cable. The number of times of twisting from 720° to the left to 720° to the right is greater than 3000 times.
[0019] As an improvement to the above solution, the area where the plurality of inner core wires 31 are arranged does not exceed half of the radius length of the cable body 12. By adopting the above solution, being in a position close to the center of the circle can reduce the stretching degree of the inner core wires 31.
[0020] As an improvement to the above solution, a corrugated tube 33 made of nylon is sleeved outside the inner rubber layer 32, and an outer rubber layer 34 is provided outside the corrugated tube 33. The corrugated tube 33 itself has appropriate strength and is used to increase the difficulty of large-angle bending of the data cable.
[0021] As an improvement to the above solution, the interaction connector 11 includes a typec port 21 at the head and a rigid plastic shell 23 at the tail. The rigid plastic shell 23 wraps at least 5 - 10 mm of the end of the cable body 12.
[0022] As an improvement of the above solution, the cross-section of the rigid plastic shell 23 is oblong, and the wire body 12 is located at the center of the rigid plastic shell 23.
[0023] The foregoing description of the specific exemplary embodiments of the present invention is for purposes of illustration and exemplification. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is apparent that many changes and variations are possible in light of the above teaching. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical applications, so that those skilled in the art can implement and utilize the various different exemplary embodiments of the present invention, as well as various different selections and changes. The scope of the present invention is intended to be defined by the claims and their equivalents.
