[0012] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0013] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention. Example
[0014] See attached Figure 1 As shown, a fire-resistant communication cable with high-density wiring includes a core 5 and an external protective structure. Six cores 5 are arranged in two rows and three columns, and two cross protection frames 6 are provided between the cores 5. A hard coating layer 4 is provided on the periphery of the core 5. A filling layer 4 is provided between the hard coating layer 4 and the core 5 and the cross protection frame 6. A flame retardant layer 2 and a waterproof membrane 3 are provided on the outside of the hard coating layer 1 in sequence.

[0017] Working principle: The wire core parts are separated by two groups of cross protection frames 6, and the wire cores are separated by polyethylene strips and inorganic microbeads. The outside of the wire core is fixed with a hard coating layer 1, which improves the integrity and density of the cable, avoids quality problems caused by wire core extrusion, and improves the adaptability to the environment. A flame retardant layer 2 and a waterproof membrane 3 are provided on the outside of the hard coating layer 1 to improve the waterproof and flame retardant properties of the cable. It has good usage capabilities and effects in a relatively single wiring environment or a long-distance environment, and meets the needs of high density.
[0018] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description. Therefore, it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model, and any figure marks in the claims should not be regarded as limiting the claims involved.
[0019] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution.
