Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of data line, and particularly relates to a data line. BACKGROUND

[0002] Since one end of the plug (for example, a charging connector) of the data line is often bent or pulled during use, the core wire at the corresponding position of the end is easily pulled off. Therefore, in the prior art, as shown in FIG. 1, a circular rod 1' with relatively high rigidity is usually arranged in the central hole of the data line 10' near the end of the plug 20', and the circular rod 1' can share the pulling force of the data line 10' to prolong the service life of the data line 10'. Figure 1

[0003] However, during the bending or pulling of the data line 10', as shown in FIG. 2, the core wire 102' and the circular rod 1' in the data line 10' will slide relative to each other, so that the sharp corners of the end face of the circular rod 1' are in contact with and pressed against the core wire 102'. After the data line 10' is used frequently, the sharp corners of the end face of the circular rod 1' will scratch and pierce the core wire 102', which finally affects the service life of the data line 10'. Figure 2 SUMMARY

[0004] The present application aims to provide a data line to solve the technical problem that the core wire of the data line in the prior art is easily scratched, which finally affects the service life of the data line.

[0005] To achieve the above object, the present application provides a data line according to a first aspect, which comprises:

[0006] a plug;

[0007] a wire body connected with the plug, the wire body comprising a central hole extending in the axial direction of the wire body and a plurality of core wires surrounding the central hole;

[0008] a central rod comprising:

[0009] a rod body arranged in the central hole;

[0010] a first scratch-preventing part arranged at one end of the rod body, the first scratch-preventing part being exposed to the outside of the central hole, and the first scratch-preventing part being arranged in the plug.

[0011] Further, the first scratch-preventing part is formed in any one of a cylindrical structure, a polyhedral structure, a spherical structure and an ellipsoidal structure.

[0012] Further, the first scratch-preventing part and the rod body are in an integral molding structure.

[0013] Further, the central rod further comprises: ​​

[0014] The second anti-scratch part is located at the other end of the rod body and inside the central hole, and the second anti-scratch part is in contact with the spherical surface of the core wire.

[0015] Furthermore, the second anti-scratch part is formed into a spherical or ellipsoidal structure.

[0016] Furthermore, the rod body, the first anti-scratch part, and the second anti-scratch part are integrally formed structures.

[0017] The present invention provides a data cable according to a second aspect embodiment, the data cable being used for connection to a plug, comprising:

[0018] A wire body, the wire body including a central hole extending along the axial direction of the wire body and a plurality of core wires surrounding the central hole;

[0019] The center rod includes:

[0020] A rod body, wherein the rod body is disposed within the central hole;

[0021] A first anti-scratch part, the first anti-scratch part having at least a portion of its structure disposed within the central hole on the side facing the plug, the portion of the first anti-scratch part within the central hole contacting the spherical surface of the core wire.

[0022] Furthermore, the first anti-scratch part is formed into a spherical or ellipsoidal structure.

[0023] Furthermore, the first anti-scratch part and the rod body are integrally formed.

[0024] Furthermore, the central rod also includes:

[0025] The second anti-scratch part is located on the other side of the rod body and inside the central hole. The second anti-scratch part is in spherical contact with the multiple core wires.

[0026] Furthermore, the second anti-scratch part is formed into a spherical or ellipsoidal structure.

[0027] Furthermore, the rod body, the first anti-scratch part, and the second anti-scratch part are integrally formed structures.

[0028] The beneficial effects of this invention are:

[0029] The data cable of the present invention includes a plug, a cable body, and a central rod. The cable body is connected to the plug. The cable body includes a central hole extending along the axial direction of the cable body and multiple core wires surrounding the central hole. The main body of the central rod is disposed within the central hole. By placing the central rod within the central hole of the cable body, the pulling force of the cable body can be distributed, thereby extending the service life of the data cable. A first anti-scratch part is provided at one end of the main body. The first anti-scratch part is exposed outside the central hole and is placed inside the plug, thereby playing a limiting role and preventing the central rod from sliding within the central hole. Furthermore, by extending the first anti-scratch part of the central rod into the plug, the edge of the end face of the main body can be prevented from scratching the core wires, further extending the service life of the data cable.

[0030] The present invention also provides a data cable, including a cable body and a central rod. The cable body includes a central hole extending along the cable body axis and multiple core wires surrounding the central hole. The main body of the central rod is disposed within the central hole. At least a portion of the first anti-scratch part of the central rod is disposed within the central hole on the side facing the plug. The portion of the first anti-scratch part within the central hole makes spherical contact with the core wires. That is, when the central rod slides within the central hole, the spherical contact between the first anti-scratch part and the core wires results in very little force between at least a portion of the first anti-scratch part and the sidewall of the core wires, thereby protecting the core wires and further extending the service life of the data cable.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

For example, they can refer to a mounting connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

[0050] In the description of this invention, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0051] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0052] like Figures 3 to 7 As shown, the present invention provides a data cable according to a first aspect embodiment, which includes a plug 20, a cable body 10, and a central rod 30. The cable body 10 is connected to the plug 20. The cable body 10 includes a central hole 103 extending axially along the cable body 10, multiple core wires 102 surrounding the central hole 103, and an outer sheath 101 covering the multiple core wires 102. The central rod 30 includes a rod body 1 and a first anti-scratch part 2. The rod body 1 is disposed in the central hole 103. By disposing the central rod 30 in the central hole 103 of the cable body 10, the central rod 30 can share the pulling force of the cable body 10, thereby extending the service life of the data cable. The first anti-scratch part 2 is exposed outside the central hole 103 and is placed inside the plug 20. That is, at one end of the rod body 1 (corresponding to...) Figure 6 The upper end of the center rod 30 is provided with a first anti-scratch part 2, which serves as a limit and can prevent the center rod 30 from sliding in the center hole 103. Furthermore, by extending the first anti-scratch part 2 of the center rod 30 into the plug 20, the edge of the end face of the rod body 1 can be prevented from scratching the core wire 102, thereby further extending the service life of the data cable.

[0053] Furthermore, the first anti-scratch part 2 is formed as any one of a cylindrical structure, a polyhedral structure, a spherical structure, and an ellipsoidal structure. That is to say, the first anti-scratch part 2 can be, for example, a cylindrical structure, a polyhedral structure, a spherical structure, or an ellipsoidal structure. It is understood that the first anti-scratch part 2 is exposed inside the plug 20 outside the central hole 103. That is, it is only necessary to ensure that the first anti-scratch part 2 is always exposed outside the central hole 103. The first anti-scratch part 2 of any shape will not scratch the core wire 102. Therefore, the shape of the first anti-scratch part 2 is not limited.

[0054] Specifically, in order for the first anti-scratch part 2 to be exposed outside the central hole 103, the radial width of the first anti-scratch part 2 should be greater than the diameter of the rod body 1 and the diameter of the central hole 103, so that the first anti-scratch part 2 remains exposed outside the central hole 103 when the data cable is pulled. It can be understood that the radial width of the first anti-scratch part 2 is the dimension in the direction perpendicular to the axial direction of the rod body 1.

[0055] More specifically, taking the first anti-scratch part 2 as an example with a spherical structure, let: the diameter of the central hole 103 be D1, corresponding to Figure 8 The central hole 103 is enclosed by a dashed circle, the diameter of which is D1; ​​as shown... Figures 7 to 9 As shown, let the diameter of the rod body 1 be D2, and the diameter (radial width) of the first anti-scratch part 2 be D3; D1, D2, and D3 should satisfy: D2 = D1 + (0.01~0.08) mm, D3 = D1 + (0.01~0.15) mm. Taking the first anti-scratch part 2 as a polyhedral structure as an example, the radial width of the first anti-scratch part 2 is D3, where the direction of this radial width is perpendicular to the axial direction of the rod body 1. D1, D2, and D3 should satisfy: D2 = D1 + (0.01~0.08) mm, D3 = D1 + (0.01~0.15) mm.

[0056] like Figure 3 , Figure 8 , Figure 10 and Figure 11 As shown, the present invention provides a data cable according to a second aspect embodiment, including a cable body 10 and a central rod 30. The cable body 10 is used to connect to a plug 20. The cable body 10 includes a central hole 103 extending axially along the cable body 10 and multiple core wires 102 surrounding the central hole 103. The central rod 30 includes a rod body 1 and a first anti-scratch portion 2. The rod body 1 is disposed within the central hole 103. By disposing the central rod 30 within the central hole 103 of the cable body 10, the central rod 30 can share the pulling force of the cable body 10, thereby extending the service life of the data cable. The first anti-scratch portion 2 has at least a partial structure disposed within the central hole 103 on the side facing the plug 20. The portion of the first anti-scratch portion 2 within the central hole 103 makes spherical contact with the core wires 102. That is, on the side of the rod body 1 facing the plug 20 (corresponding to...) Figure 10 The upper end of the cable is provided with a first anti-scratch part 2, which is located inside the center hole 103 and makes contact with the spherical surface of the core wire 102. This can prevent the edge of the end face of the rod body 1 facing the plug 20 from scratching the core wire 102, thereby protecting the core wire 102 and extending the service life of the data cable.

[0057] Furthermore, the first anti-scratch part 2 is formed into a spherical or ellipsoidal structure. That is, the first anti-scratch part 2 is provided in the central hole 103. By forming a spherical or ellipsoidal structure, the first anti-scratch part 2 forms an arc-shaped outer surface. When the data cable is pulled, the side of the rod body 1 of the central rod 30 facing the plug 20 will come into contact with and squeeze the core wire 102 as the data cable twists. The first anti-scratch part 2 forms a spherical contact with the side wall of the core wire 102, which can prevent the edge of the end face of the rod body 1 facing the plug 20 from scratching the core wire 102, thus further extending the service life of the data cable.

[0058] In a preferred embodiment of the present invention, the first anti-scratch part 2 and the rod body 1 are integrally formed. That is, the first anti-scratch part 2 and the rod body 1 are formed integrally to obtain the center rod 30, which facilitates processing and simplifies the assembly process between the center rod 30 and the data cable 10. It is understood that whether the first anti-scratch part 2 is exposed outside the center hole 103 or is disposed within the center hole 103, an integral center rod 30 can be formed, thus possessing the aforementioned advantages.

[0059] In a preferred embodiment of the present invention, the center rod 30 further includes a second anti-scratch part 3, which is disposed at the other end of the rod body 1 and located within the center hole 103. The second anti-scratch part 3 is in spherical contact with the core wire 102. That is, at the other end of the rod body 1 (corresponding to...) Figure 9 and Figure 11 A second anti-scratch part 3 is provided at the lower end of the first anti-scratch part 2. The second anti-scratch part 3 is located inside the central hole 103 and makes spherical contact with the core wire 102. This can prevent the edge of the other end of the rod body 1 from scratching the core wire 102, thereby further protecting the core wire 102 and extending the service life of the data cable. It can be understood that, for both the first anti-scratch part 2 exposed outside the central hole 103 and the first anti-scratch part 2 located inside the central hole 103, a second anti-scratch part 3 can be provided on the rod body 1 at the opposite end of the first anti-scratch part 2, thereby further protecting the core wire 102 and extending the service life of the data cable.

[0060] The second scratch-resistant part 3 is formed into a spherical or ellipsoidal structure. That is, by forming a spherical or ellipsoidal structure, the second scratch-resistant part 3 has an arc-shaped outer surface. When the data cable is pulled, the other end of the central rod 30 may come into contact with and be squeezed against the core wire 102 due to the twisting of the data cable. This results in a spherical contact between the second scratch-resistant part 3 and the sidewall of the core wire 102, preventing the edge of the other end of the central rod 30 from scratching the core wire 102 and further extending the service life of the data cable. It is understandable that, whether for the first scratch-resistant part 2 exposed outside the central hole 103 or for the first scratch-resistant part 2 located inside the central hole 103, the second scratch-resistant part 3 located at the opposite end of the first scratch-resistant part 2 can be formed into a spherical or ellipsoidal structure, thereby allowing the second scratch-resistant part 3 to make spherical contact with the core wire 102 and further extending the service life of the data cable.

[0061] It is worth noting that during assembly, the other end of the center rod 30 is inserted into the center hole 103 first. That is, the other end of the center rod 30 with the second anti-scratch part 3 is inserted into the center hole 103. The spherical or ellipsoidal structure of the second anti-scratch part 3 can prevent scratching the core wire 102 during insertion (assembly), which can improve the assembly yield. In addition, the second anti-scratch part 3 also plays a guiding role, making it easier for the center rod 30 to pass into the center hole 103, which can improve the assembly efficiency. It can be understood that, whether for the first anti-scratch part 2 exposed outside the center hole 103 or for the first anti-scratch part 2 set inside the center hole 103, the spherical or ellipsoidal structure of the second anti-scratch part 3 can protect the core wire 102 and guide it, so that the data cable center rod 30 can pass into the center hole 103, thereby improving the assembly yield.

[0062] Furthermore, the rod body 1, the first anti-scratch part 2, and the second anti-scratch part 3 are integrally molded structures. That is, the first anti-scratch part 2, the rod body 1, and the second anti-scratch part 3 are formed integrally, resulting in the center rod 30. This facilitates processing and simplifies the assembly process between the center rod 30 and the data cable body 10. In addition, the integrally molded center rod 30 ensures coaxiality, preventing compression of the core wire 102 due to low axial accuracy of the center rod 30, thus affecting the lifespan of the data cable. It is understood that whether the first anti-scratch part 2 is exposed outside the center hole 103 or is located inside the center hole 103, an integral center rod 30 can be formed, thus possessing the aforementioned advantages.

[0063] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
