[0031] The specific implementation methods of the present application are further described in detail below with reference to the accompanying drawings.

[0032] like Figures 1 to 3As shown, this embodiment provides a tearable high-speed parallel wire 100 , including an outer sheath 20 and a plurality of parallel wire pairs 10 .

[0033] For the convenience of subsequent reading, the present application introduces a first direction Z, a second direction X, and a third direction Y to describe the embodiments of the present application. The first direction Z, the second direction X, and the third direction Y may be three non-parallel linear directions in space; further, the first direction Z, the second direction X, and the third direction Y may be three mutually perpendicular directions in a three-dimensional coordinate system (three-dimensional Cartesian coordinate system). In the subsequent embodiments, the first direction Z is the Z-axis direction of the coordinate axis of the three-dimensional coordinate system, the second direction X is the X-axis direction of the coordinate axis of the three-dimensional coordinate system, and the third direction Y is the Y-axis direction of the coordinate axis of the three-dimensional coordinate system.

[0034] The extension direction of the outer sheath 20 is parallel to the third direction Y, and a housing cavity 201 is provided in the outer sheath 20, so that the entire outer sheath 20 is arranged in a circular ring structure. A first tearing groove 202 is provided on the outer circumference of the outer sheath 20, and a first positioning groove 203 is provided on the inner circumference of the outer sheath 20. A plurality of parallel line pairs 10 are arranged in the housing cavity 201, and a plurality of parallel line pairs 10 are arranged parallel to each other, and the extension direction of the parallel line pairs 10 is parallel to the third direction Y. The parallel line pairs 10 include a line pair body 11 and at least two rotating members 12. A rotating groove 114 is provided on the outer circumference of the line pair body 11. The rotating groove 114 is arranged around the axis of the line pair body 11. At least two rotating members 12 are partially rotatably arranged in the rotating groove 114, so that each rotating member 12 can rotate around the axis of the line pair body 11. The first positioning groove 203 is configured to accommodate at least a portion of the rotating member 12 outside the rotating groove 114 , and at least one rotating member 12 of the parallel line pair 10 is configured to abut against the rotating member 12 of the adjacent parallel line pair 10 .

[0035] Thus, the tearable high-speed parallel line 100 of the present application is convenient for the user to tear the outer sheath 20 at the first tearing groove 202 and take out the parallel line pair 10 inside by setting the first tearing groove 202 on the outer peripheral surface of the outer sheath 20. In addition, the parallel line pair 10 is composed of a line pair body 11 and a rotating member 12, and the rotating member 12 can rotate around the line pair body 11, so that when the parallel line pair 10 is disassembled and assembled into a new high-speed parallel line for use, the position of the rotating member 12 of each parallel line pair 10 can be adjusted. On the one hand, the rotating member 12 of each parallel line pair 10 is aligned with the first positioning groove 203 to limit the position of each parallel line pair 10, and on the other hand, the rotating members 12 between each parallel line pair 10 are abutted against each other to support each parallel line pair 10, or a shielding structure 40 is formed between each parallel line pair 10 through the rotating member 12 to avoid signal crosstalk and other problems between two adjacent parallel line pairs 10.

[0036] Please combine again Figures 1 to 3 In one embodiment, the wire pair body 11 includes two wire cores 111, a sheath layer 112, and a ground wire 113. The two wire cores 111 are arranged in parallel, and the extension direction of the wire cores 111 is parallel to the third direction Y. The sheath layer 112 is wrapped around the outer circumference of the two wire cores 111, so that the two wire cores 111 are protected by the sheath layer 112. The ground wire 113 is arranged in the sheath layer 112, and the ground wire 113 is located between the two wire cores 111, which can reduce the interference between the two wire cores 111 and ensure the stability of signal transmission.

[0037] The wire core 111 includes a wire 1111 and an insulating layer 1112 wrapped around the outer circumference of the wire 1111. The wire 1111 is an aluminum wire or the like. The insulating layer 1112 may be made of a polytetrafluoroethylene (PTFE) composite material or a polyimide (PI) composite material to ensure that the insulating layer 1112 has excellent electrical insulation performance. The provision of the insulating layer 1112 of the two wire cores 111 can preliminarily ensure signal crosstalk between the two wire cores 111.

[0038] Furthermore, the sheath layer 112 includes a first shielding layer 1121, a second shielding layer 1122 and an inner shielding layer 1123 which are sequentially wrapped around the outer circumference of the two cores 111. The first shielding layer 1121 and the second shielding layer 1122 are made of materials with electromagnetic shielding functions such as aluminum or copper. Through the composite shielding structure of the first shielding layer 1121 and the second shielding layer 1122, the two cores 111 can be well protected from interference and the normal operation of the cores 111 can be ensured. The inner shielding layer 1123 is wrapped around the outer circumference of the second shielding layer 1122, which can well protect the second shielding layer 1122 and avoid damaging the second shielding layer 1122. The inner shielding layer 1123 is made of materials such as polyethylene or polytetrafluoroethylene, which has good insulation. In addition, the inner shielding layer 1123 is made of such a material, which can have a certain structural strength to support the rotating member 12 to rotate around it.

[0039] Please combine again Figures 1 to 3In one embodiment, the rotation groove 114 is provided on the outer circumference of the inner sheath 1123, and the rotation groove 114 extends inward from the outer circumference of the inner sheath 1123, and the extension depth is about 1 / 3 to 1 / 2 of the thickness of the inner sheath 1123, and the first shielding layer 1121 and the second shielding layer 1122 are provided in cooperation with each other to prevent the portion of the rotating member 12 installed in the rotation groove 114 from exerting a large pressure on the wire core 111 and causing damage to the wire core 111. The rotation groove 114 is provided around the outer circumference of the inner sheath 1123 to ensure that the rotating member 12 can rotate around the outer circumference of the inner sheath 1123. Along the third direction Y, the inner walls of the opposite sides of the rotation groove 114 are provided with limiting grooves 115, and the two limiting grooves 115 are provided around the outer circumference of the inner sheath 1123. Along the first direction Z, the depth of the limiting groove 115 is less than the depth of the rotating groove 114, and the bottom wall of the limiting groove 115 is coplanar with the bottom wall of the rotating groove 114, so that the cross-sectional shape of the groove body formed after the rotating groove 114 and the limiting groove 115 are connected is roughly "convex".

[0040] Furthermore, the rotating member 12 includes a first rotating portion 121 and a second rotating portion 122 , and the first rotating portion 121 and the second rotating portion 122 are integrally formed.

[0041] The first rotating portion 121 is generally a rectangular structure, one end of which is rotatably disposed in the rotating groove 114. Along the third direction Y, the extension length of the first rotating portion 121 is the same as the extension length of the rotating groove 114. The second rotating portion 122 is generally a cylindrical structure, which is located outside the rotating groove 114 and is integrally formed at the other end of the first rotating portion 121. The first positioning groove 203 at least partially accommodates the second rotating portion 122, so as to limit the position of the second rotating portion 122 through the first positioning groove 203, and further limit the position of the parallel line pair 10 where the second rotating portion 122 is located. The shape of the groove wall of the first positioning groove 203 is generally a curved surface, so as to adapt to the shape of the second rotating portion 122. The second rotating portions 122 of multiple parallel line pairs 10 can abut against each other, so as to limit the position of the parallel line pairs 10 where each second rotating portion 122 is located through the second rotating portions 122 abutting against each other.

[0042] Along the third direction Y, the first rotating part 121 is provided with a limiting column 1210 at two opposite ends thereof, and the limiting column 1210 is roughly a cylindrical structure. The two limiting columns 1210 are rotatably arranged in the two limiting grooves 115, so that the limiting columns 1210 can rotate around the inner protective layer 1123 in the limiting grooves 115. In addition, along the radial direction of the inner protective layer 1123, the two opposite sides of the limiting column 1210 respectively abut against the two inner walls of the limiting groove 115, so as to limit the first rotating part 121 in the radial direction of the inner protective layer 1123. Along the third direction Y, the two opposite ends of the two limiting columns 1210 respectively abut against the inner walls of the two limiting grooves 115, so as to limit the first rotating part 121 in the third direction Y.

[0043] Please combine again Figures 1 to 3 In one embodiment, the tearable high-speed parallel wire 100 further includes an inner sheath 30, which is disposed in the accommodating cavity 201, and the inner sheath 30 is spaced apart from the outer sheath 20. The inner sheath 30 is provided with a parallel wire pair 10, and the inner sheath 30 and the outer sheath 20 are provided with a parallel wire pair 10, so that the plurality of parallel wire pairs 10 are arranged in layers, which can avoid problems such as signal crosstalk caused by too many parallel wire pairs 10 being arranged in the same layer.

[0044] A plurality of parallel line pairs 10 are provided between the inner sheath 30 and the outer sheath 20. The plurality of parallel line pairs 10 are arranged around the outer circumference of the inner sheath 30 and around the axis of the inner sheath 30, and the plurality of parallel line pairs 10 abut against each other. When the plurality of parallel line pairs 10 abut against each other, the plurality of parallel line pairs 10 between the inner sheath 30 and the outer sheath 20 can form a ring structure after abutting against each other, thereby improving the position stability of these parallel line pairs 10. For example, the plurality of parallel line pairs 10 between the inner sheath 30 and the outer sheath 20 are arranged at intervals from each other along the circumferential direction, and a rotating member 12 is provided on the adjacent side of two adjacent parallel line pairs 10, and the two rotating members 12 are located in the space between the two adjacent parallel line pairs 10, and the two rotating members 12 abut against each other, so as to realize the abutment between the plurality of parallel line pairs 10 between the inner sheath 30 and the outer sheath 20, and the plurality of parallel line pairs 10 abut against each other through the rotating member 12, because the rotating member 12 can rotate relative to the parallel line pairs 10 When the tearable high-speed parallel wire 100 is affected by external factors such as impact, the rotating parts 12 between each parallel wire pair 10 can be relatively offset to play a buffering role, thereby protecting the parallel wire pairs 10, and through a small deflection of the rotating parts 12 relative to the parallel wire pairs 10, it can also ensure that the parallel wire pairs 10 will not be offset due to external forces such as impact, thereby ensuring the parallelism between the parallel wire pairs 10, thereby improving the impact resistance, bending performance, and signal transmission stability of the entire tearable high-speed parallel wire 100.

[0045] The outer circumference of the inner sheath 30 is provided with a second positioning groove 32, and the second positioning groove 32 at least partially accommodates the second rotating part 122. The second positioning groove 32 extends inward from the outer circumference of the inner sheath 30, and the groove wall of the second positioning groove 32 is a curved surface to match the shape of the second rotating part 122, thereby ensuring the stability of the second rotating part 122 when it is limited in the second positioning groove 32.

[0046] There are multiple second positioning grooves 32, and the multiple second positioning grooves 32 are evenly and spacedly arranged around the outer circumference of the inner sheath 30. The multiple first positioning grooves 203 are arranged one-to-one with the multiple second positioning grooves 32, and the number of the second positioning grooves 32 and the first positioning grooves 203 is the same as the number of the parallel line pairs 10 between the inner sheath 30 and the outer sheath 20, so that the two rotating members 12 on any parallel line pair 10 between the inner sheath 30 and the outer sheath 20 are respectively clamped in the corresponding first positioning grooves 203 and the second positioning grooves 32.

[0047] It is worth noting that the parallel line pair 10 located between the inner sheath 30 and the outer sheath 20 cooperates with the second positioning groove 32 of the inner sheath 30 and the first positioning groove 203 of the outer sheath 20 through two rotating parts 12, so that the parallel line pair 10 can swing to a certain extent relative to the inner sheath 30 and the outer sheath 20 around the axis of the second rotating part 122. When the tearable high-speed parallel line 100 is subjected to a large external force, the parallel line pair 10 located between the inner sheath 30 and the outer sheath 20 is subjected to a large external force and swings to a certain extent, thereby reducing the impact of the external force on it, avoiding the parallel line pair 10 directly being subjected to a large external force and breaking and other problems, and improving the service life of the parallel line pair 10 located in the tearable high-speed parallel line 100. In addition, the line connecting the first positioning groove 203 and the second positioning groove 32 corresponding to any parallel line pair 10 located between the inner sheath 30 and the outer sheath 20 passes through the center point of the parallel line pair 10 to ensure that the swing amplitude of the parallel line pair 10 when swinging to either side is roughly consistent, thereby improving the stability of the parallel line pair 10 during positioning and swinging.

[0048] Furthermore, the outer circumference of the inner sheath 30 is provided with a plurality of second tearing grooves 31, which are evenly and spaced apart around the outer circumference of the inner sheath 30, and the plurality of second tearing grooves 31 are alternately spaced apart with the plurality of second positioning grooves 32. Along the radial direction of the inner sheath 30, any second tearing groove 31 is located at the middle position of two adjacent parallel line pairs 10.

[0049] The cross-sectional shape of the second tear groove 31 is substantially an isosceles triangle, and the extending direction of the second tear groove 31 is parallel to the third direction Y, so as to facilitate taking out the parallel wire pair 10 in the inner sheath 30 after tearing the inner sheath 30 through the second tear groove 31 .

[0050] In this embodiment, there are multiple first tearing grooves 202, and multiple second tearing grooves 31 are arranged one by one corresponding to the multiple first tearing grooves 202. The cross-sectional shape of the first tearing groove 202 is roughly an isosceles triangle, and the extension direction of the first tearing groove 202 is also parallel to the third direction Y, so that the parallel wire pair 10 located between the outer sheath 20 and the inner sheath 30 can be taken out after the outer sheath 20 is torn open from the first tearing groove 202. In this way, the present application adopts this structural form of layered arrangement of parallel line pairs 10 and tear wire grooves on both the outer sheath 20 and the inner sheath 30. When a problem occurs with the parallel line pairs 10 outside the inner sheath 30 but no problem occurs with the parallel line pairs 10 inside the inner sheath 30, only the outer sheath 20 is torn open to take out the parallel line pairs 10 outside the inner sheath 30, and the inner sheath 30 and the parallel line pairs 10 inside can be used separately as double-pair high-speed parallel lines or can be recycled and then parallel line pairs 10 are arranged outside and then covered with a new outer sheath 20 for continued use, further improving the service life and flexibility of use of the tearable high-speed parallel line 100 of the present application.

[0051] Please combine again Figures 1 to 3 In one embodiment, the outer sheath 20 includes a first outer sheath 21, a third shielding layer 22, and a second outer sheath 23. The first outer sheath 21 is arranged to form a receiving cavity 201, and the parallel line pair 10 is located in the first outer sheath 21. The third shielding layer 22 is wrapped around the outer circumference of the first outer sheath 21, and the second outer sheath 23 is wrapped around the outer circumference of the third shielding layer 22.

[0052] The third shielding layer 22 is made of a material with electromagnetic shielding function such as aluminum or copper, which can provide good anti-interference protection for the parallel line pairs 10 located in the third shielding layer 22 and ensure the normal operation of the parallel line pairs 10 .

[0053] It is understandable that the number of the third shielding layers 22 may also be two, and the combination of the two third shielding layers 22 can enhance the electromagnetic shielding function.

[0054] The third shielding layer 22 is sandwiched between the first outer sheath 21 and the second outer sheath 23, which can provide good protection for the third shielding layer 22 and avoid damage to the third shielding layer 22. The first outer sheath 21 and the second outer sheath 23 are made of polyethylene or polytetrafluoroethylene, which has good insulation.

[0055] The first positioning groove 203 is formed on the inner circumference of the first outer sheath 21, and the first tearing groove 202 is formed on the outer circumference of the second outer sheath 23. The first outer sheath 21 has good structural strength to ensure that it can stably limit the rotation member 12 in the first positioning groove 203.

[0056] Please combine again Figures 1 to 3In one embodiment, two parallel line pairs 10 are disposed in the inner sheath 30, and the two parallel line pairs 10 are spaced apart along the first direction Z. The second rotating portions 122 of the plurality of rotating members 12 of the two parallel line pairs 10 are located between the two parallel line pairs 10. And along the second direction X, the second rotating portions 122 of the plurality of rotating members 12 of the two parallel line pairs 10 are staggered and abut against each other, so as to form a shielding structure 40 between the two parallel line pairs 10.

[0057] Among the two parallel line pairs 10 located in the inner sheath 30, the two second rotating parts 122 of one parallel line pair 10 are arranged at intervals along the second direction X, and the two second rotating parts 122 of the other parallel line pair 10 are arranged at intervals, and one of the second rotating parts 122 is located between the two second rotating parts 122 of the aforementioned parallel line pair 10. The rotating member 12 is made of a material with electromagnetic shielding function. When the four second rotating parts 122 are arranged closely in sequence along the second direction X, the shielding structure 40 formed by the four second rotating parts 122 can prevent the two parallel line pairs 10 located in the inner sheath 30 from having problems such as signal crosstalk. In addition, the adjacent sides of the two parallel line pairs 10 are abutted against each other through the second rotating parts 122, and the opposite sides of the two parallel line pairs 10 are both pressed against the inner circumferential surface of the inner sheath 30, so that the position limiting between the two parallel line pairs 10 located in the inner sheath 30 is also achieved through the rotating member 12.

[0058] It can be understood that in other embodiments, the parallel line pairs 10 located in the inner sheath 30 can also be provided with three rotating parts 12 or other numbers of rotating parts 12. The shielding structure 40 is formed by staggered arrangement of the second rotating parts 122 of six rotating parts 12 in total of two parallel line pairs 10. The length of the shielding structure 40 in the second direction X can be increased to fill more areas between the two parallel line pairs 10, thereby improving the ability of the shielding structure 40 to resist signal crosstalk.

[0059] Please combine again Figure 4 , and see Figure 1 and Figure 2 In one embodiment, two groups of parallel line pairs 10 are provided in the inner sheath 30, and the two groups of parallel line pairs 10 are arranged in sequence along the second direction X. Each group of parallel line pairs 10 includes two parallel line pairs 10, and the two parallel line pairs 10 are arranged at intervals along the first direction Z. The second rotating parts 122 of the multiple rotating members 12 of the two parallel line pairs 10 are located between the two parallel line pairs 10, and along the second direction X, the second rotating parts 122 of the multiple rotating members 12 of the two parallel line pairs 10 are staggered and abut against each other, so as to form a shielding structure 40 between the two parallel line pairs 10. The structure and principle of the shielding structure 40 are the same as those of the above-mentioned shielding structure 40, and will not be repeated here.
