[0044] See Figures 1a to 4 , Figure 1a This is a structural diagram of an embodiment of a data line provided by this application. Figure 1b yes Figure 1a A local enlarged schematic diagram of area S, Figure 2 yes Figure 1a A structural diagram of an embodiment of a data cable body of a data cable is provided. Figure 3 yes Figure 1a A cross-sectional schematic diagram of an embodiment of a data line body of a data line is provided. Figure 4 yes Figure 1a A cross-sectional schematic diagram of another embodiment of a data cable body of a data cable is provided.
[0045] See also Figures 1a to 4 The present application provides a data cable 100, which includes a data cable body 1 and a connector 3. The data cable body 1 includes an insulating layer 14 and multiple core wires, and the insulating layer 14 wraps the multiple core wires. The connector 3 is connected to one end of the data cable body 1. The connector 3 includes a connector 31, which is located at the end of the connector 3 away from the data cable body 1.
[0046] See also Figures 1a to 2A plurality of protrusion pairs 11 are provided on the outer side surface of the insulating layer 14. The plurality of protrusion pairs 11 are arranged at intervals along the axial direction of the data line body 1. Each protrusion pair 11 includes a first protrusion 111 and a second protrusion 112. The first protrusion 111 and the second protrusion 112 both extend spirally around the axial direction of the data line body 1, and the spiral extension directions of the first protrusion 111 and the second protrusion 112 are opposite.
[0047] It can be understood that by providing a plurality of protrusion pairs 11 on the outer side surface of the insulating layer 14 of the data cable body 1, the first protrusion 111 and the second protrusion 112 of each protrusion pair 11 both extend in an axial spiral around the data cable body 1, and the spiral extension directions are opposite, and a specific texture design is formed on the outer side surface of the insulating layer 14, which can effectively improve the stress concentration problem of the insulating layer 14 of the data cable body 1, avoid damage to the insulating layer 14 of the data cable body 1 or breakage of the core wire in the insulating layer 14, effectively improve the bending and breakage resistance of the insulating layer 14 of the data cable body 1, and the structure is simple and the cost is low, which effectively improves the service life of the data cable 100, and solves the problem of easy damage and breakage and short service life of the data cable in the prior art.
[0048] Specifically, in some embodiments, the spiral angles of the first protrusion 111 and the second protrusion 112 of each protrusion pair 11 can be the same; in other embodiments, the spiral angles of the first protrusion 111 and the second protrusion 112 of each protrusion pair 11 can also be different, which can be designed as needed.
[0049] Specifically, in some embodiments, the helix angle of the first protrusion 111 of each protrusion pair 11 is within a range of 30-60°.

Preferably, the helix angle of the second protrusion 112 of each protrusion pair 11 is 45°. It will be understood that by setting the helix angle of the first protrusion 111 and / or the helix angle of the second protrusion 112 within a range of 30-60°, the insulating layer 14 of the data cable body 1 will be subjected to more uniform force, which can be more conducive to improving the stress concentration problem of the data cable 100, more effectively improving the data cable 100's resistance to bending and breakage, and increasing the service life of the data cable 100.
[0050] In some preferred embodiments, the helix angles of the first protrusion 111 and the second protrusion 112 of each protrusion pair 11 are both within a range of 30-60°. The helix angles of the first protrusion 111 and the second protrusion 112 of each protrusion pair 11 can be the same or different. More preferably, the helix angles of the first protrusion 111 and the second protrusion 112 of each protrusion pair 11 are the same, both being 45°. This allows the data cable body 1 to be subjected to more uniform force and to be more resistant to bending and breakage.

[0053] In some embodiments, in each protrusion pair 11, the first end 1111 of the first protrusion 111 is connected to the third end 1121 of the second protrusion 112.

It can be understood that the first parting line 101 and the second parting line 102 are respectively the first parting protrusion 12 and the second parting protrusion 13 disposed on the outer side of the insulating layer 14, which can further enhance the bending and breakage resistance of the data cable 100 and help reduce the precision requirements and manufacturing costs of the mold used to prepare the insulating layer 14 of the data cable body 1, thereby saving costs.
[0064] For details, see Figure 1a 、 Figure 1b 、 Figure 5 、 Figure 9 In one embodiment, in each protrusion pair 11, the first end 1111 and the third end 1121 are connected to the same position on the first parting protrusion 12, and the second end 1112 and the fourth end 1122 are connected to the same position on the second parting protrusion 13.

Preferably, the first protrusion 111 and the second protrusion 112 in each protrusion pair 113 have the same helix angle and lead, that is, the first protrusion 111 and the second protrusion 112 extend for the same length, which further improves stress concentration in the data cable body 1 and enhances the bending and breakage resistance of the data cable 100. In other embodiments, the first parting protrusion 12 may extend in an axial spiral around the data cable body 1, and / or the second parting protrusion 13 may also extend in an axial spiral around the data cable body 1, and the spiral angles of the first protrusion 111 and the second protrusion 112 may be different.

[0066] In other embodiments, the outer side surface of the insulating layer 14 may not be provided with the first parting protrusion 12 and the second parting protrusion 13, that is, the first parting line 101 and the second parting line 102 can be virtual lines (busbars) or solid lines on the outer side surface of the insulating layer 14, and in each protrusion pair 11, the first end 1111 and the third end 1121 can be directly located on the first parting line 101, and the second end 1112 and the fourth end 1122 can be located on the second parting line 102, or, the first end 1111 and the third end 1121 can be spaced apart on both sides of the first parting line 101, and the second end 1112 and the fourth end 1122 can be spaced apart on both sides of the second parting line 102.
[0067] In some embodiments, among the plurality of protrusion pairs 11 on the outer side surface of the insulating layer 14, the distance between any two adjacent first protrusions 111 is equal, and / or the distance between any two adjacent second protrusions 112 is equal. Preferably, the distance between any two adjacent first protrusions 111 and the distance between any two adjacent second protrusions 112 are both equal, that is, the first protrusions 111 and the second protrusions 112 of the plurality of protrusion pairs 11 are evenly distributed, so that the force applied to the data line 100 is more evenly distributed, which is more conducive to improving the problem of stress concentration, improving the data line 100's resistance to bending and breakage, and thereby extending the service life of the data line 100.
[0068] Specifically, in some embodiments, the cross-sectional shape of the first protrusion 111 and the second protrusion 112 is the same. In a specific embodiment, as shown in FIG. Figure 3 As shown, the cross-sectional shapes of the first protrusion 111 and the second protrusion 112 are both rectangular, and the sizes of the first protrusion 111 and the second protrusion 112 are equal and remain unchanged along the circumference of the insulating layer 14. Figure 4 As shown, in another specific embodiment, the cross-sectional shape of the first protrusion 111 and the second protrusion 112 are both triangular, and the heights of the first protrusion 111 and the second protrusion 112 gradually change along the circumference of the insulating layer 14. The first protrusion 111 and the second protrusion 112 can also be set to other shapes and can be designed as needed.
[0069] See also Figure 3 and Figure 4 In some embodiments, the data cable body 1 further includes a first shielding layer 15 and a second shielding layer 16, the second shielding layer 16 covers the inner surface of the insulating layer 14, the first shielding layer 15 covers the inner surface of the second shielding layer 16, and the first shielding layer 15 wraps a plurality of core wires, wherein the connector 31 of the connector portion 3 of the data cable 100 is used to connect a mobile device or a computer, and the plurality of core wires include two power lines 17, two ground lines 18, four signal lines 19 or a configuration channel electronic line (CC) 10 to achieve the purpose of data transmission and communication.
[0070] See also Figure 1a In some embodiments, the data cable 100 further includes a protective cover 2, which is disposed between the data cable body 1 and the connector portion 3, and an end of the data cable body 1 close to the connector portion 3 is inserted into the protective cover 2. The protective cover 2 can be used to protect the end of the data cable body 1 close to the connector portion 3, thereby improving the problem of damage to the data cable 100 and breakage of multiple core wires caused by stress concentration at the connection position between the data cable body 1 and the connector portion 3, thereby improving the data cable 100's resistance to bending and breakage and extending the service life of the data cable 100.
[0071] Specifically, such as Figure 1a As shown, the outer side surface of the protective sleeve 2 is provided with a plurality of groove pairs 21, and the plurality of groove pairs 21 are arranged at intervals along the axial direction of the protective sleeve 2. Each groove pair 21 includes a first groove 211 and a second groove 212. The first groove 211 and the second groove 212 both extend spirally along the axial direction of the protective sleeve 2, and the spiral extension directions of the first groove 211 and the second groove 212 are opposite.
[0072] Specifically, the spiral angles of the first groove 211 and the second groove 212 of each groove pair 21 can be the same or different, and can be designed as needed. In some embodiments, the spiral angle of the first groove 211 of each groove pair 21 is in the range of 30-60°. Preferably, the spiral angle of the first groove 211 of each groove pair 21 is 45°. In some embodiments, the spiral angle of the second groove 212 of each groove pair 21 is in the range of 30-60°. Preferably, the spiral angle of the second groove 212 of each groove pair 21 is 45°. It can be understood that by setting the spiral angle of the first groove 211 and / or the spiral angle of the second groove 212 in the range of 30-60°, the protective cover 2 will be more evenly stressed, which can be more conducive to improving the stress concentration problem of the data cable 100, more effectively improving the bending and breakage resistance of the data cable 100, and improving the service life of the data cable 100.
[0073] In some preferred embodiments, the helix angles of the first groove 211 and the second groove 212 of each groove pair 21 are both within a range of 30-60°. The helix angles of the first groove 211 and the second groove 212 of each groove pair 21 can be the same or different. More preferably, the helix angles of the first groove 211 and the second groove 212 of each groove pair 21 are the same, both being 45°. This allows the protective cover 2 to be subjected to more uniform force and to have greater resistance to bending and breakage.
[0074] Specifically, the arrangement of the first groove 211 and the second groove 212 of the groove pair 21 on the outer side surface of the protective cover 2 can refer to the arrangement of the first protrusion 111 and the second protrusion 112 of the protrusion pair 11 on the outer side surface of the insulating layer 14 in any of the above-mentioned embodiments, and can achieve the same or similar technical effects, which will not be repeated here.
[0075] In order to verify the anti-bending and anti-breakage capability of the data cable of the present application, the applicant conducted a swing test using the data cable of the present application. Specifically, the number of data cable samples is 5, and the sample structure is the same as Figure 1a The data cables shown have the same structure, and the five data cable samples are numbered 1#, 2#, 3#, 4#, and 5#. All five data cable samples were subjected to the same swing test using the same test equipment under the same test conditions. Specifically, the five data cable samples were vibrated or swung on the same test equipment, such as a swing table. The frequency, amplitude, and duration of the vibration or sway were identical for each swing test. All five data cable samples were subjected to 30,231 swing tests, resulting in the test results shown in the following table:
[0076] Sample number Number of tests Test situation 1# 30231 After testing, the data cable functions normally and has no appearance damage. 2# 30231 After testing, the data cable functions normally and has no appearance damage. 3# 30231 After testing, the data cable functions normally and has no appearance damage. 4# 30231 After testing, the data cable functions normally and has no appearance damage. 5# 30231 After testing, the data cable functions normally and has no appearance damage.
[0077] The applicant analyzed the test results and found that after subjecting all five data cable samples to the same 30,231 swing tests, all five data cable samples were tested for performance. Specifically, all five data cable samples continued to function normally, including charging, and none of the five data cable samples appeared to be damaged. These test results demonstrate that the data cable structure of the present application has excellent resistance to bending and breakage, effectively improving the stress concentration problem of data cables in the prior art and resolving the issues of easy breakage and fracture, as well as the short service life, that exist in the prior art.
