[0028] Reference Figure 1-3 The utility model provides a high-strength communication cable, comprising:

[0029] The main unit 100 includes a protective sleeve 101, an aramid composite layer 104 is disposed inside the protective sleeve 101, and an empty groove 206 is opened inside the aramid composite layer 104;

[0030] The internal unit 200 includes a silicone soft rod 201 arranged inside 106, and five groups of silicone soft rods 203 are arranged on the sides of the silicone soft rod 1 201. Each group of silicone soft rods 203 is fixedly connected to a plurality of groups of silicone soft rods 202 on one side of the silicone soft rod 1 201, and the other ends of the silicone soft rods 202 are fixedly connected to the silicone soft rod 1 201. A cable body 204 is arranged between every two groups of silicone soft rods 202, and a constraint layer 205 is arranged on the surface of the cable body 204. The side of each group of silicone soft rods 203 facing away from the silicone soft rod 1 201 is in contact with the inner wall of the empty groove 206.

[0031] The interior of the empty slot 206 is filled with nitrogen, and the nitrogen is in contact with the surface of the constraining layer 205, which has the function of isolating temperature, so that the operating temperature of the cable body 204 will not be conducted outward.

[0032] Furthermore, five groups of cable bodies 204 are evenly arranged in a circle with the silicone soft rod 201 as the center, and the outer surface of each group of constraint layers 205 is in contact with the silicone soft rod 202, so that the five groups of cable bodies 204 are evenly distributed inside the empty groove 206, and can be displaced to disperse the pressure when squeezed.

[0033] Furthermore, a flame retardant layer 103 is provided on the surface of the aramid composite layer 104, and the flame retardant layer 103 is made of flame retardant polyurethane and is used to prevent fire and self-extinguishing. It can not only protect the cable body 204 from damage by fire, but also has good heat resistance and can remain stable at high temperatures.

[0034] Furthermore, the surface of the flame retardant layer 103 is provided with an anti-cutting layer 102, and the anti-cutting layer 102 is made of steel brushed weaving, which is used to isolate external electromagnetic radiation and interference signals. It can not only shield external signal interference to a limited extent, but also prevent cutting and protect the internal cable body 204.

[0035] Furthermore, a plurality of anti-skid particles 109 are fixedly connected to the outer side of the protective cover 101, and the anti-skid particles 109 are made of rubber material, so they will not slide during installation, and are convenient for workers to hold.

[0036] During use, under the protection of the anti-cutting layer 102 and the flame retardant layer 103, the high temperature generated by the cable body 204 during operation will be blocked by nitrogen by the internal unit 200, thereby reducing the conduction capacity to the outside world, preventing the internal temperature of the protective sleeve 101 from being too high and causing internal damage to the protective sleeve 101. At the same time, with the setting of the silicone soft rod 1 201, the silicone soft rod 202 and the silicone soft rod 2 203, when the protective sleeve 101 is squeezed, the cable body 204 will be dislocated and deflected to disperse and transfer the pressure.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
