Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a cold-resistant and flame-retardant cable. Background Technology

[0002] Currently, people's need for rapid data and information transmission has led to a significant and rapid increase in reliance on computers, word processors, telex, sensors, and communication equipment. The emergence of new technologies has made it possible to connect and network these devices, resulting in the comprehensive development of communication systems. The use of these systems in specific fields is increasing, such as high-rise buildings, ships, airplanes, trains, drilling platforms, and mines. In order to connect these electronic components, a large number of wires and cables are needed in these structures and fields.

[0003] Currently, the outer sheath of cables is generally made of ordinary flexible materials, which are easily ignited and lack fire resistance after ignition. In cold conditions such as winter, the low external temperature and cold air penetrating the cable surface may cause the overall temperature of the cable to drop, which may affect the transmission performance of the cable itself. Therefore, it is necessary to design a cold-resistant and flame-retardant cable. Utility Model Content

[0004] The main purpose of this utility model is to provide a cold-resistant and flame-retardant cable, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A cold-resistant and flame-retardant cable includes a transmission copper wire and a second fireproof layer. An insulation layer is fixedly connected to one side of the outer surface of the transmission copper wire, and a shielding layer is fixedly connected to one side of the outer surface of the insulation layer. The shielding layer is made of copper-plated wire. A reinforcing layer is fixedly connected to one side of the outer surface of the shielding layer. The reinforcing layer is made of glass fiber. A first fireproof layer is provided on one side of the outer surface of the reinforcing layer. A filling cavity is provided on the outer surface of the first fireproof layer, and a flame retardant is provided on the inner wall of the filling cavity.

[0007] In order to enable the heating function, as a cold-resistant and flame-retardant cable of this utility model, a cable heating strip is provided on one side of the outer surface of the second fireproof layer.

[0008] To prevent heat loss, the cold-resistant and flame-retardant cable of this invention has an insulation layer on one side of the outer surface of the heating band, and the insulation layer is made of polyurethane.

[0009] To prevent external cold air from entering, the cold-resistant and flame-retardant cable of this utility model has insulation cotton on one side of the outer surface of the insulation layer.

[0010] To secure the insulation cotton, a cable tie is provided on one side of the outer surface of the insulation cotton, which is a cold-resistant and flame-retardant cable of this utility model.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. In this utility model, by setting up a transmission copper wire, a second fireproof layer, an insulation layer, a first fireproof layer and a flame retardant, in specific use, when a fire source appears on the outside of the cable, when the fire source reaches the second fireproof layer, the second fireproof layer can block the fire source and produce an initial fireproof effect. When the second fireproof layer is damaged, the flame retardant in the filling cavity is exposed and inhibits the combustion of the fire source to a certain extent. In addition, the first fireproof layer can play a secondary fireproof effect, thereby ensuring the normal operation of the cable as a whole, so that the cable itself has certain fireproof and flame-retardant properties.

[0013] 2. In this utility model, by setting up a cable heating layer, an insulation layer, insulation cotton, and cable ties, the cable heating belt can heat the cable itself to a certain extent during use, thereby enabling the cable to regulate its temperature in cold conditions such as winter. The insulation layer prevents the warm air generated by the cable heating belt from dissipating, and the cable ties fix the insulation cotton to the outer surface of the insulation layer, preventing external cold air from penetrating the cable, thus achieving better insulation and cold protection effects and improving the cable's cold resistance.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-4 As shown, a cold-resistant and flame-retardant cable includes a transmission copper wire 1 and a second fireproof layer 01. An insulation layer 2 is fixedly connected to one side of the outer surface of the transmission copper wire 1. A shielding layer 3 is fixedly connected to one side of the outer surface of the insulation layer 2. The shielding layer 3 is made of copper-plated wire. A reinforcing layer 4 is fixedly connected to one side of the outer surface of the shielding layer 3. The reinforcing layer 4 is made of glass fiber.

[0021] In this embodiment, a first fireproof layer 5 is provided on one side of the outer surface of the reinforcing layer 4, a filling cavity 6 is provided on the outer surface of the first fireproof layer 5, and a flame retardant 7 is provided on the inner wall of the filling cavity 6.

[0022] In practical use, when a fire source appears on the outside of the cable, when the fire source reaches the second fireproof layer 01, the second fireproof layer 01 can block the fire source and produce an initial fireproof effect. When the second fireproof layer 01 is damaged, the flame retardant 7 in the filling cavity 6 is exposed and suppresses the combustion of the fire source to a certain extent. In addition, the first fireproof layer 5 can play a secondary fireproof effect, thereby ensuring the normal operation of the cable as a whole. This gives the cable itself certain fireproof and flame-retardant properties. The shielding layer 3 can reduce the obstruction of the cable operation by external magnetic field and other interference signals.

[0023] In this embodiment, a cable heating strip 8 is provided on one side of the outer surface of the second fireproof layer 01.

[0024] In practical use, the cable heating belt 8 can heat the cable itself to a certain extent, thereby enabling the cable to regulate its temperature in cold conditions such as winter.

[0025] In this embodiment, an insulation layer 9 is provided on one side of the outer surface of the cable heating strip 8, and the insulation layer 9 is made of polyurethane.

[0026] In practical use, the insulation layer 9 is made of polyurethane, which has good heat insulation performance and makes it difficult for the heat generated by the cable heating strip 8 to dissipate.

[0027] In this embodiment, insulation cotton 10 is provided on one side of the outer surface of the insulation layer 9.

[0028] In practical use, the insulation cotton 10 can prevent external cold air from penetrating the inside of the cable under cold conditions.

[0029] In this embodiment, a cable tie 11 is provided on one side of the outer surface of the thermal insulation cotton 10.

[0030] In practical use, the cable ties 11 can fix the position of the insulation cotton 10, thereby improving the stability of the insulation cotton 10.

[0031] Working principle: During use, when a fire source appears on the outside of the cable, when the fire source reaches the second fireproof layer 01, the second fireproof layer 01 can block the fire source and produce an initial fireproof effect. When the second fireproof layer 01 is damaged, the flame retardant 7 in the filling cavity 6 is exposed and inhibits the combustion of the fire source to a certain extent. The first fireproof layer 5 can also play a secondary fireproof role, thereby ensuring the normal operation of the cable as a whole. This gives the cable itself certain fireproof and flame-retardant properties. The shielding layer 3 can reduce the obstruction of the cable operation by external magnetic field and other interference signals. When the cable heating belt 8 is used, it can heat the cable itself to a certain extent, thereby allowing the cable to regulate its temperature in cold conditions such as winter. The insulation layer 9 can prevent the warm current generated by the cable heating belt 8 from dissipating. The cable tie 11 fixes the insulation cotton 10 to the outer surface of the insulation layer 9, which can prevent external cold air from penetrating the cable, thereby achieving a better insulation and cold protection effect and improving the cold resistance of the cable.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
