Technical Field

[0001] The present application relates to the technical field of communication cables, and in particular to a flame-retardant communication cable. Background Art

[0002] At present, cables are widely used in power transmission, distribution, and the transmission of various signals, and are applicable to various occasions such as power stations, power grids, industrial and mining enterprises, railway transportation, buildings, subways, telegraph offices, etc. Cables are usually used to conduct electric power and communication signals, and are generally divided into two types: power cables and communication cables.

[0003] Regarding the above related technologies, the inventor believes that for existing flame-retardant communication cables, in some humid environments, during the connection between cables or during the connection and installation between a cable and a cable connector, the connection steps of the cable are too complex, resulting in too low installation efficiency when multiple cables are connected and installed.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will further describe the present application in detail Figures 1-3 with reference to the accompanying drawings.

[0021] The embodiment of the present application discloses a flame retardant communication cable. Refer to Figures 1-3, a flame-retardant communication cable, comprising a communication cable body 1. A waterproof sleeve 12 is slidably connected to the outer wall of the communication cable body 1, and a threaded ring 11 is fixedly connected to the side outer wall of the waterproof sleeve 12. The threaded ring 11 is slidably connected to the communication cable body 1. By passing the communication cable body 1 through the waterproof sleeve 12 and the threaded ring 11, the waterproof sleeve 12 facilitates the sealing of the connection between two cables and is convenient for waterproofing in a humid environment. A threaded sleeve 10 is slidably sleeved on the outer wall of the communication cable body 1 on one side of the waterproof sleeve 12, and the threaded sleeve 10 is threadedly connected to the threaded ring 11. By threadedly connecting the threaded sleeve 10 and the threaded ring 11, the sealing degree of the waterproof sleeve 12 is improved. At the same time, the contact between the threaded sleeve 10 and the communication cable body 1 is closely fitted. A connecting sleeve 13 is provided between the two waterproof sleeves 12, and the connecting sleeve 13 is threadedly connected to both waterproof sleeves 12. By threadedly connecting the two waterproof sleeves 12 and the connecting sleeve 13, a relatively sealed environment is formed, thereby sealing the cable connection;

[0022] The communication cable body 1 includes an outer sheath 101, and an armor layer 102 is bonded to the inside of the outer sheath 101. The armor layer 102 facilitates protection against rats, insects and animals from gnawing. A flame-retardant layer 103 is bonded to the inside of the armor layer 102. The flame-retardant layer 103 facilitates protection against high-temperature flame impact, thereby improving the flame retardancy of the cable and enabling the cable to have a fireproof line. A compressive inner layer 104 is bonded to the inside of the flame-retardant layer 103. The compressive inner layer 104 is made of a soft elastic material. The compressive inner layer 104 facilitates the elastic effect inside the communication cable body 1, enabling the cable to receive a buffering effect. A plurality of insulating layers 106 are provided inside the compressive inner layer 104, and a plurality of cable cores 107 are provided inside the insulating layers 106. The insulating layers 106 play an insulating role for the plurality of cable cores 107.

[0023] A fixed filling layer 105 is filled on one side of the inner wall of the compressive inner layer 104 where the plurality of insulating layers 106 are located. The fixed filling layer 105 supports and fixes the plurality of insulating layers 106.

[0024] The flame-retardant layer 103 is made of a fiberglass fabric material, preferably the CYB26-PF-2540H type. This material can withstand high-temperature flame impact of 1400 degrees.

[0025] A male-female joint 9 is provided on the side outer wall of the communication cable body 1, and the cable core 107 is electrically connected to the male-female joint 9. The male-female joint 9 facilitates the connection between two cables and enables them to be connected in the connecting sleeve 13.

[0026] Sealing rings 14 are sleeved on both sides of the connecting sleeve 13. The sealing rings 14 facilitate improving the sealing between the connecting sleeve 13 and the waterproof sleeve 12.

[0027] The implementation principle of a flame-retardant communication cable in an embodiment of the present application is as follows: First, the communication cable body 1 is passed through the threaded sleeve 10 and the threaded ring 11 into the waterproof sleeve 12. Then, the threaded sleeve 10 and the threaded ring 11 are threadedly connected. Next, the male buckle in the male-female joint 9 on the communication cable body 1 is connected to the female buckle on another cable, thereby connecting the two cables. At the same time, two sealing rings 14 are sleeved on both sides of the connecting sleeve 13, so that the waterproof sleeves 12 on both sides of the connecting sleeve 13 are threadedly connected to the connecting sleeve 13, thus completing the sealed installation of the two cables. At the same time, the flame-retardant layer 103 in the communication cable body 1 enables the cable to have the properties of high-temperature resistance and flame retardancy, protecting the cable core 107 inside the communication cable body 1 and facilitating the improvement of the fire resistance of the communication cable.
