[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] Embodiment one, please refer to Figure 1 Figure 4 In the embodiments of the present application, a coaxial cable double-layer protection structure includes a conductor 100, the outer side of the conductor 100 is wrapped with an insulating layer 200, the top of the insulating layer 200 is provided with a jack 210 capable of allowing the conductor 100 to be movably inserted, the outer side of the insulating layer 200 is wrapped with a fireproof material 300, the outer side of the fireproof material 300 is wrapped with a shielding layer 400, the outer side of the shielding layer 400 is wrapped with an outer protective layer 500, the inner part of the outer protective layer 500 is axially uniformly embedded and fixed with a reinforcing iron wire 510, a protective rubber sleeve 600 is fixedly sleeved between two coaxial cables, and a plurality of supporting rubber strips 610 are uniformly fixed at the inner middle position of the protective rubber sleeve 600 in a ring shape.

[0029] Specifically, the jack 210 is provided in the insulating layer 200 of the traditional coaxial cable, which facilitates the insertion and installation of the conductor 100 into the insulating layer 200 when the two coaxial cables are butt-jointed and installed, thereby improving the efficiency of the butt-joint installation of the coaxial cables, the fireproof material 300 is filled between the shielding layer 400 and the insulating layer 200, which can prevent the conductor 100 from causing a fire due to a short circuit, the protective rubber sleeve 600 is sleeved at the connection position of the two coaxial cables, which will be fixed at the connection position of the two coaxial cables under the condition of heating, and meanwhile, the plurality of supporting rubber strips 610 in the protective rubber sleeve 600 can support the connection position of the two cables, which is conducive to improving the tensile and bending resistance of the cables to achieve the effect of multi-layer protection of the coaxial cables.

[0030] The conductor 100 is made of copper or copper alloy material, which can efficiently transport current, and the insulating layer 200 is made of flame-retardant polyethylene material, which is conducive to improving the insulation and fireproof performance of the conductor 100.

[0031] For example Figure 4 ​As shown, in this embodiment, the shielding layer 400 is a metal foil woven mesh structure, and the fireproof material 300 is filled and fixed between the insulating layer 200 and the shielding layer 400, so that the shielding layer 400 can resist electromagnetic interference and noise.

[0032] like Figure 4 As shown, in this embodiment, the outer sheath 500 is made of wear-resistant plastic material, and a waterproof layer 520 is fixed between the outer sheath 500 and the shielding layer 400. The waterproof layer 520 can effectively prevent external moisture from entering the cable and avoid short circuits and other situations inside the cable.

[0033] like Figure 1 As shown, in this embodiment, the inner diameter of the protective sleeve 600 is larger than the diameter of the outer sheath 500, so that the protective sleeve 600 can be fitted and installed between two cables to be connected.

[0034] In the above embodiment, during the installation of the protective sleeve 600, the protective sleeve 600 is first fitted onto the outside of the outer sheath 500 of a cable. After the conductors 100 and shielding layers 400 of the two cables are connected, the protective sleeve 600 is moved and fitted onto the connection position of the two cables. Then, a lighter or other heating device is used to heat the protective sleeve 600 so that the protective sleeve 600 supports the connection position of the two cables.

[0035] like Figure 4 As shown, in this embodiment, an extension is fixed on the outer side of the insulating layer 200, and a socket 210 is opened at the extension position, so that the conductor 100 can be conveniently inserted into the socket 210. In the initial state, the inner diameter of the socket 210 is smaller than the diameter of the conductor 100, which facilitates the deformation of the socket 210 position of the insulating layer 200 during the insertion of the conductor 100, thus firmly binding the position of the conductor 100.

[0036] like Figure 4 As shown, in this embodiment, the inner side of the fireproof material 300 is provided with an arc-shaped recessed area, and the extension of the outer side of the insulating layer 200 is embedded in the arc-shaped recessed area, so that the fireproof material 300 can adapt to the shape of the insulating layer 200 and be embedded and fixed together with the insulating layer 200.
