[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figures 1-3This utility model provides a technical solution: a halogen-free, low-smoke, flame-retardant, and fire-resistant communication power flexible cable, including a conductor 1, which has multiple conductors 1, each conductor 1 including multiple strands of fine copper wires, the multiple strands of copper wires being twisted together to form a flexible structure; a wrapping structure 2 is wrapped around the outside of the conductor 1; the halogen-free, low-smoke, flame-retardant, and fire-resistant communication power flexible cable also includes a buffer structure 4, the buffer structure 4 being disposed outside all the wrapping structures 2, and a filling structure 3 filling the space between the wrapping structures 2 and the buffer structure 4.

[0027] An insulating sleeve 5 is fitted over the outside of the buffer structure 4, and a fire-resistant structure 6 is provided over the outside of the insulating sleeve 5.

[0028] The wrapping structure 2 uses mica tape, which is wrapped around the outside of the core 1.

[0029] The filling structure 3 uses halogen-free, low-smoke, flame-retardant rope. Through tight filling, the overall structure composed of core 1, wrapping structure 2, and filling structure 3 is rounded. The filling structure 3 uses halogen-free, low-smoke, flame-retardant rope to achieve buffering and support functions, thereby enhancing the overall mechanical properties.

[0030] The buffer structure 4 includes a buffer sleeve 41, which is fixedly covered on the outside of the filling structure 3. The buffer structure 4 can be made of elastic materials such as rubber or silicone, which can improve the buffering effect and thus enhance the protection of its internal structure.

[0031] The insulation sleeve 5 is made of halogen-free, low-smoke, flame-retardant polyolefin material, and the fire-resistant structure 6 is made of halogen-free, low-smoke, flame-retardant wrapping tape. The halogen-free, low-smoke, flame-retardant wrapping tape is wrapped around the outside of the insulation sleeve 5 to improve the overall flame-retardant performance of the cable and prevent the flame from spreading inside the cable.

[0032] In this embodiment, the flame-retardant and fire-resistant performance of the entire cable is improved by setting the wrapping structure 2 and the fire-resistant structure 6; at the same time, the filling structure 3 and the buffer structure 4 are set to enhance the buffering effect and improve the protection of the conductor 1.

[0033] Example 2 Please see Figures 1-5 Based on Embodiment 1, this embodiment has a plurality of elongated holes 42 on the buffer sleeve 41, which are arranged in a circular array. At the same time, two L-shaped buffer strips 43 are provided inside each elongated hole 42, and the two L-shaped buffer strips 43 inside each elongated hole 42 are arranged symmetrically at the center. The L-shaped buffer strips 43 and the buffer sleeve 41 are integrally formed, and the L-shaped buffer strips 43 and the buffer sleeve 41 are made of the same material.

[0034] In this embodiment, by providing an elongated hole 42 on the buffer sleeve 41, the elastic deformation of the buffer sleeve 41 is facilitated; at the same time, an L-shaped buffer strip 43 is provided, which facilitates the elastic deformation of the two L-shaped buffer strips 43 when the buffer sleeve 41 is compressed, thereby enhancing the buffering effect.

[0035] Example 3 See again Figures 1-3 Based on Embodiment 2, this embodiment adds an outer sheath 7 to the outside of the fire-resistant structure 6. The outer sheath 7 is made of halogen-free, low-smoke, flame-retardant polyolefin material, which is used to improve the mechanical strength of the entire cable and protect its internal structure from external environmental corrosion.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
