Description

Technical Field

[0001] The utility model belongs to the technical field of twisted-pair wires, in particular to an environmentally friendly flame-retardant twisted-pair wire. Background Art

[0002] Twisted Pair (TP) is the most commonly used transmission medium in integrated wiring projects. It is composed of two copper wires with an insulating protective layer. The two insulated copper wires are twisted together at a certain density. The radio waves radiated by each wire during transmission will be offset by the radio waves emitted by the other wire, effectively reducing the degree of signal interference. During the construction process of power engineering personnel, twisted pair cables are often needed to lay some circuits.

[0003] Although the existing environmentally friendly flame-retardant twisted pair cables have the advantages of flame retardancy and fire resistance, the outer surface of the twisted pair cables is easily rubbed during the laying process, causing damage to the outer surface of the twisted pair cables, resulting in reduced flame retardancy of the twisted pair cables, affecting the subsequent use of the twisted pair cables. Therefore, an environmentally friendly flame-retardant twisted pair cable is proposed to address the above problems. Utility Model Content

[0004] In order to solve the problems raised in the above-mentioned background technology, the utility model provides an environmentally friendly flame-retardant twisted pair cable, which can solve the problem that the outer surface of the twisted pair cable is easily subjected to friction during the laying process, causing damage to the outer surface of the twisted pair cable, resulting in reduced flame retardancy of the twisted pair cable, and affecting the subsequent use of the twisted pair cable.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an environmentally friendly flame-retardant twisted pair cable, comprising a fireproof shell, the outer surface of which is equidistantly fixedly connected with a protective ring, the interior of the fireproof shell is provided with an insulating layer, the inner wall of the insulating layer is fixedly connected with a reinforcement net, and the interior of the reinforcement net is fixedly connected with a rubber layer.

[0006] Preferably, a conductor is provided inside the rubber layer, and the conductor is made of copper alloy.

[0007] Preferably, an outer surface of the protective ring is provided with an anti-oxidation coating, and a diameter of the protective ring is larger than a diameter of the fireproof shell.

[0008] Preferably, the rubber layer is made of metal foil, and the inner wall of the rubber layer is provided with a waterproof coating for increasing the waterproof property.

[0009] Preferably, the insulating layer is made of polyvinyl chloride, and the insulating layer is used to prevent electromagnetic interference.

[0010] Preferably, the inner wall of the fireproof shell is provided with a waterproof layer for increasing the waterproof property, and the outer surface of the fireproof shell is provided with a flame retardant coating for flame retardancy.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model, through the arrangement of the fireproof shell and the protective ring, when the workers are laying the conductor, the fireproof shell rubs against the ground or the designated working position, the protective ring isolates the fireproof shell from the friction position, and then the protective ring will first touch the friction position, so that the fireproof shell can reduce friction, thereby playing a role in protecting the outer surface of the fireproof shell.

[0013] 2. The utility model, through the provision of a fireproof shell, a reinforcement net and an insulating layer, can isolate the external fire source by its fireproof shell when the conductor is in an accidental environment during use, so that the conductor has high temperature resistance, thereby meeting the needs of various application scenarios.

[0019] 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 the embodiments. 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.

[0020] like Figures 1 to 4 As shown, the utility model provides an environmentally friendly flame-retardant twisted pair cable, including a fireproof shell 1, the outer surface of which is equidistantly fixedly connected with a protective ring 2, the outer surface of which is affixed with an anti-oxidation coating, and the diameter of the protective ring 2 is larger than the diameter of the fireproof shell 1.

[0021] When using environmentally friendly flame-retardant twisted pair cables, when the line installer is laying the conductor 6, the protective ring 2 first touches the ground or the designated working position during the laying process, and then the protective ring 2 assists the conductor 6 in sliding laying, thereby reducing the occurrence of friction damage to the outer surface of the fireproof shell 1.

[0022] like Figures 1 to 4 As shown, an insulating layer 3 is provided inside the fireproof shell 1, a rubber layer 5 is fixedly connected to the inside of the reinforcement net 4, a conductor 6 is provided inside the rubber layer 5, the conductor 6 is made of copper alloy, the rubber layer 5 is made of metal foil, the inner wall of the rubber layer 5 is pasted with a waterproof coating for increasing the waterproof property, the insulating layer 3 is made of polyvinyl chloride, and the insulating layer 3 is used to prevent electromagnetic interference.

[0023] By setting the insulating layer 3, when the conductor 6 is energized, the conductor 6 starts to be energized, and then the insulating layer 3 effectively isolates the external interfering magnetic force, thereby playing a role in facilitating the normal operation of the protective conductor 6;

[0024] By setting the rubber layer 5, during the use of the conductor 6, its fireproof shell 1 often needs to be placed in the air, and the moisture in the air continuously erodes the fireproof shell 1, and then the rubber layer 5 isolates the external moisture, thereby improving the waterproofness of the conductor 6.

[0025] like Figures 1 to 4 As shown, the inner wall of the insulating layer 3 is fixedly connected with a reinforcing net 4, the inner wall of the fireproof shell 1 is provided with a waterproof layer for increasing waterproofness, and the outer surface of the fireproof shell 1 is provided with a flame retardant coating for flame retardancy.

[0026] By providing the reinforcing net 4, when the conductor 6 is accidentally bent during use, the reinforcing net 4 reinforces the interior of the fireproof shell 1, thereby preventing the conductor 6 from being squeezed and causing accidental deformation of the conductor 6.

[0027] The working principle and use process of the utility model are as follows: first, when using environmentally friendly flame-retardant twisted pair cables, during the process of laying the conductor 6, the protective ring 2 of the line installer first touches the ground or the designated working position during the laying process, and then the protective ring 2 assists the conductor 6 in sliding laying. When the conductor 6 is energized, the conductor 6 starts to be energized, and then the insulating layer 3 effectively isolates the external interfering magnetic force. During the use of the conductor 6, the fireproof shell 1 often needs to be placed in the air, and the moisture in the air continuously erodes the fireproof shell 1, and then the rubber layer 5 isolates the external moisture. Finally, when the conductor 6 is accidentally bent, the reinforcement net 4 reinforces the inside of the fireproof shell 1, thereby avoiding the conductor 6 from being squeezed and causing the conductor 6 to be accidentally deformed.
