Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0020] Specific implementation examples are given below.

[0021] Please see Figure 1 and Figure 2 As shown in the embodiment of this utility model, a thermal insulation cable includes multiple cable bodies 1. A shielding layer 13 is provided on the outside of each cable body 1. A filling layer 12 is provided between the shielding layer 13 and the cable body 1. A protective layer 14 is provided outside the shielding layer 13. A reinforcing layer 15 is provided outside the protective layer 14. During operation, the filling layer 12, which can be made of rock wool, fills the spaces between the multiple cable bodies 1. Rock wool has excellent fireproof and thermal insulation properties, effectively improving the thermal insulation and fireproof performance of the cable body 1 when it generates heat. Simultaneously, the shielding layer 13, which can be made of tinned copper wire braided mesh, provides excellent electromagnetic shielding performance and flexibility, effectively protecting the internal signal transmission of the cable body 1 from external interference and reducing its outward electromagnetic interference radiation. This also ensures that the cable body 1... The cable exhibits excellent flexibility and bendability during operation, facilitating installation and use. A protective layer 14, which can be made of silicone rubber (due to its excellent flexibility, insulation, and temperature resistance), is provided outside the shielding layer 13 to effectively protect the shielding layer 13 and internal components. A reinforcing layer 15, which can be made of fiberglass braid, is then provided outside the protective layer 14. Fiberglass's tear resistance and abrasion resistance effectively protect the remaining internal components from external damage. A filling layer 12 is provided outside the cable body 1 to effectively insulate and fireproof the cable body 1, improving its safety and stability during use. The reinforcing layer 15, outside the protective layer 14, enhances the cable body 1's tear resistance while providing insulation, extending its service life.

[0022] Please see Figure 2As shown, the filling layer 12 is provided with a connecting rod 2 inside; a plurality of partitions 22 are fixedly connected to the middle of the connecting rod 2; the partitions 22 and the cable body 1 are correspondingly arranged; by filling the filling layer 12 with connecting rods 2 and partitions 22, the partitions 22 will isolate the plurality of cable bodies 1, reduce the direct contact between the cable bodies 1 during operation, and reduce the electromagnetic field interference between the cable bodies 1.

[0023] Please see Figure 2 As shown, the end of the partition 22 is provided with a top plate 3; the top plate 3 and the shielding layer 13 are in contact; the top plate 3 supports the shielding layer 13, increases the surface tension of the shielding layer 13, reduces the deformation of the shielding layer 13 caused by cable bending, and improves the structural strength of the shielding layer 13 itself.

[0024] Please see Figure 2 As shown, the surface of the partition 22 is provided with a plurality of top rods 4; the top rods 4 are equidistantly arranged; by setting the top rods 4, the top rods 4 will fill the interior of the filling layer 12, thereby improving the structural rigidity of the interior of the filling layer 12.

[0025] Please see Figure 2 As shown, there are three cable bodies 1; there are six top rods 4 located on both sides of the cable body 1; because the top rods 4 are located on both sides of the cable body 1, the top rods 4 can support the cable body 1, reduce the contact between the cable body 1 and other components during operation, and reduce wear caused by friction.

[0026] Please see Figure 2 As shown, the connecting rod 2, top plate 3, and top rod 4 are all insulated; the connecting rod 2, top plate 3, and top rod 4 are all flexible. Because the connecting rod 2, top plate 3, and top rod 4 are insulated and flexible, static electricity will not adhere to their surfaces during installation, and the flexibility of the cable will not be affected during use, thus improving its safety.

[0027] Working Principle: A filling layer 12, which can be made of rock wool, is filled between multiple cable bodies 1. Rock wool has excellent fire resistance and heat insulation properties, effectively improving the heat insulation and fire resistance of the cable body 1 when it generates heat during operation. A shielding layer 13, which can be made of tinned copper wire braid, is provided outside the filling layer 12. Tinned copper wire braid has excellent electromagnetic shielding performance and flexibility, effectively protecting the internal signal transmission of the cable body 1 from external interference and reducing its outward electromagnetic interference radiation. It also ensures the cable body 1 has good flexibility and bendability during operation, facilitating installation and use. A protective layer 14, which can be made of silicone rubber, is provided outside the shielding layer 13. Silicone rubber has good flexibility, insulation, and temperature resistance, effectively protecting the shielding layer 13 and internal components. Finally, a reinforcing layer 15, which can be made of fiberglass braid, is provided outside the protective layer 14. Fiberglass has tear resistance and abrasion resistance. The performance of the top plate 3 is as follows: it effectively protects the remaining components inside the reinforcing layer 15 from external damage; by filling the filling layer 12 with connecting rods 2 and partitions 22, the partitions 22 isolate multiple cable bodies 1, reducing direct contact between cable bodies 1 during operation and reducing electromagnetic interference between cable bodies 1; the top plate 3 supports the shielding layer 13, increases the surface tension of the shielding layer 13, reduces deformation of the shielding layer 13 due to cable bending, and improves the structural strength of the shielding layer 13 itself; by setting the top rods 4, the top rods 4 fill the interior of the filling layer 12, increasing the structural rigidity of the filling layer 12; because the top rods 4 are located on both sides of the cable body 1, the top rods 4 can support the cable body 1, reducing contact between the cable body 1 and other components during operation and reducing wear caused by friction; because the connecting rods 2, top plate 3, and top rods 4 are all insulated and flexible, static electricity will not adhere to their surfaces during installation, and the flexibility of the cable will not be affected during use, improving its safety during use.
