Description

Technical Field

[0001] This application belongs to the field of cable manufacturing technology, specifically relating to a new type of high roundness cable. Background Technology

[0002] In existing technologies, cables play a crucial role in many fields such as power transmission and communication. They effectively enable long-distance transmission of electrical energy or signals, ensuring the normal operation of various equipment and systems. However, traditional cables often suffer from insufficient roundness in practical applications. In scenarios where high roundness is required, the hexagonal strands can lead to uneven outer diameters, affecting the overall performance and appearance of the cable. For example, when cables are used inside precision machinery or in locations where aesthetically pleasing wiring is paramount, an uneven outer diameter can cause unnecessary interference with surrounding components or negatively impact the overall layout. Furthermore, poorly rounded cables may exhibit suboptimal protective effects during subsequent protective treatments, such as sheathing and threading, due to the uneven outer diameter, potentially increasing operational difficulty and costs. Therefore, improvements are urgently needed to comprehensively enhance the performance and applicability of cables, meeting the demands of diverse application scenarios and improving their reliability and practicality.

[0016] Combination Figure 1 The following description further illustrates the technical solution proposed in this application. This application provides a novel high roundness cable, comprising a conductor 1, an insulation layer 2 covering the outer periphery of the conductor 1, a shielding layer 3 covering the outer periphery of the insulation layer 2, and a sheath layer group 4 covering the outer periphery of the shielding layer 3. The conductor 1 includes a first conductor 10, multiple second conductors 11 wound around the outer periphery of the first conductor 10, and multiple third conductors 12 wound around the outer periphery of the second conductors 11. The third conductors 12 include a fourth conductor 13 and a fifth conductor 14, which are alternately arranged around the outer periphery of the second conductors 11. The cross-sectional diameter of the fourth conductor 13 is smaller than the cross-sectional diameter of the fifth conductor 14.

[0017] This application provides a novel high roundness cable, comprising a conductor, an insulation layer surrounding the conductor, a shielding layer surrounding the insulation layer, and a sheath layer surrounding the shielding layer. The conductor includes a first conductor, multiple second conductors wound around the first conductor, and multiple third conductors wound around the second conductors. The third conductors include a fourth conductor and a fifth conductor, which are alternately arranged around the second conductor. The cross-sectional diameter of the fourth conductor is smaller than that of the fifth conductor. By alternately winding fourth and fifth conductors of different diameters, the internal gaps within the conductor are reduced, effectively improving the roundness of the cable and avoiding the uneven outer diameter problem caused by traditional hexagonal stranded wires. This improves the overall performance and appearance of the cable, offering advantages such as novel structure, convenient processing, and ease of implementation.

[0018] In this embodiment, the second conductor 11 has a total of 6 strands, the third conductor 12 has a total of 12 strands, and the number of strands of the fourth conductor 13 is equal to the number of strands of the fifth conductor 14.

[0019] In this embodiment, the cross-sectional diameter of the first conductor 10 is defined as R1, the cross-sectional diameter of the second conductor 11 is defined as R2, the cross-sectional diameter of the fourth conductor 13 is defined as R4, and the cross-sectional diameter of the fifth conductor 14 is defined as R5. R1, R2, R4, and R5 satisfy the following relationship: R1=R2, 1.25≤R5 / R4≤1.75.

[0020] In this embodiment, the first conductor 10 is formed by twisting 15-25 strands of first wire monofilament, the second conductor 11 is formed by twisting 10-15 strands of second wire monofilament, the fourth conductor 13 is formed by twisting 10-15 strands of fourth wire monofilament, and the fifth conductor 14 is formed by twisting 15-25 strands of fifth wire monofilament.

[0021] In this embodiment, the cross-sectional diameter of the first conductor filament is 0.3mm-0.4mm, the cross-sectional diameter of the second conductor filament is 0.1mm-0.2mm, the cross-sectional diameter of the fourth conductor filament is 0.1mm-0.2mm, and the cross-sectional diameter of the fifth conductor filament is 0.1mm-0.2mm.

[0022] In actual implementation, the cross-sectional diameter of the first conductor filament is 0.4 mm, the cross-sectional diameter of the second conductor filament is 0.2 mm, the cross-sectional diameter of the fourth conductor filament is 0.15 mm, and the cross-sectional diameter of the fifth conductor filament is 0.2 mm.

[0023] In actual implementation, by alternating the fourth conductor 13 and the fifth conductor 14, with the cross-sectional diameter of the fourth conductor 13 being smaller than that of the fifth conductor 14, conductors of different diameters fill the gaps during the stranding process of the wire core 1, forming a more compact and regular wire core structure. Compared to traditional cables, this structure effectively improves the roundness of the cable, avoids gaps and depressions caused by uneven conductor arrangement, and thus improves the overall performance and appearance quality of the cable.

[0024] In this embodiment, the first conductor 10 is twisted in the left direction, the second conductor 11 is twisted in the right direction, and the fourth conductor 13 and the fifth conductor 14 are both twisted in the left direction.

[0025] In practical implementation, by designing the stranding directions of the first, second, fourth, and fifth conductors separately, the torsional stress during cable manufacturing and use can be effectively reduced, improving the overall stability and roundness of the cable. During cable manufacturing, conductors with different stranding directions restrain each other, resulting in a tighter bond between the entire core. This reduces gaps and depressions caused by uneven conductor arrangement, thereby improving the roundness of the cable and avoiding the uneven outer diameter problem caused by traditional hexagonal stranded wires.

[0026] In this embodiment, a filling unit 5 is also included, which is filled between the wire core 1 and the insulation layer 2. The filling unit 5 is made of any one of rubber particles, polyester fiber, glass fiber, polyurethane particles, or aramid fiber.

[0027] In actual implementation, polyurethane particles are selected as the material for the filling unit. This choice has the following advantages:

[0028] Firstly, the structure of cable cores is relatively complex, and there may be some irregular shapes or gaps. Polyurethane particles can fill these gaps, making the core shape more complete and full.

[0029] Secondly, the polyurethane granules provide additional support for the cable, making the conductor more stable during cable manufacturing. This helps prevent deformation or displacement of the conductor during winding or stranding, thereby improving the cable's roundness.

[0030] Thirdly, during cable manufacturing, uneven shrinkage may occur due to the different coefficients of thermal expansion of different materials. The addition of polyurethane particles can alleviate this uneven shrinkage, allowing the cable to maintain a more rounded shape after cooling.

[0031] Fourth, the filling of polyurethane particles makes the cable shape more regular, reducing the problem of uneven outer diameter caused by irregular core shapes. This helps to improve the overall performance of the cable, making it more compliant with high standards.

[0032] Fifth, the filling of polyurethane particles can enhance the flexibility of the cable, enabling it to maintain good roundness when bent or twisted, and preventing cable deformation caused by excessive bending.

[0033] In this embodiment, the material of the shielding layer 3 is selected from any one of aluminum foil, copper foil, aluminum wire woven mesh, copper wire woven mesh, and steel wire woven mesh.

[0034] In actual implementation, aluminum foil is selected as the material for the shielding layer.

[0035] In this embodiment, the sheath layer group 4 includes a first sheath layer 40 covering the outer periphery of the shielding layer 3, and a second sheath layer 41 covering the first sheath layer 40. The material of the first sheath layer 40 is selected from any one of polyvinyl chloride, polyethylene, ethylene propylene rubber, and mica tape, and the material of the second sheath layer 41 is selected from any one of polytetrafluoroethylene, polyurethane, and nylon.

[0036] This application provides a novel high roundness cable, comprising a conductor, an insulation layer surrounding the conductor, a shielding layer surrounding the insulation layer, and a sheath layer surrounding the shielding layer. The conductor includes a first conductor, multiple second conductors wound around the first conductor, and multiple third conductors wound around the second conductors. The third conductors include a fourth conductor and a fifth conductor, which are alternately arranged around the second conductor. The cross-sectional diameter of the fourth conductor is smaller than that of the fifth conductor. By alternately winding fourth and fifth conductors of different diameters, the internal gaps within the conductor are reduced, effectively improving the roundness of the cable and avoiding the uneven outer diameter problem caused by traditional hexagonal stranded wires. This improves the overall performance and appearance of the cable, offering advantages such as novel structure, convenient processing, and ease of implementation.
