Description

Technical Field

[0001] The present application relates to the field of cable technology, and more specifically, to a communication cable for use in a high temperature environment. Background Art

[0002] With the development of science and technology and the progress of society, people have higher and higher requirements for the speed, distance, quality and security of information transmission, which has promoted the continuous development and innovation of communication cable technology.

[0003] With the rapid development of modern communication technology, the performance requirements for communication cables are getting higher and higher. The demand for communication cables in high-temperature working environments such as high-temperature boiler rooms, high-temperature unmanned forging workshops, steel smelting and high-temperature sol machines is increasing. However, when using existing communication cables in high-temperature environments, the following technical problems will occur:

[0004] 1) Temperature changes will affect the physical properties of communication cable lines. For example, the thermal expansion coefficient of communication cables will change with temperature, which may cause changes in the length and shape of the cable. If the wire strength of the communication cable is insufficient, the change in the length and shape of the cable is uncontrollable or exceeds the design range, which may cause the cable to break or the connection to fail.

[0005] 2) Temperature changes will affect the conductor material of the communication cable, because different materials have different resistance temperature coefficients. When the ambient temperature of the communication cable increases, its resistance will also increase. The increase in resistance will cause signal attenuation and reduce the signal transmission effect of the communication cable. Utility Model Content

[0036] The first polytetrafluoroethylene tape 5 has extraordinary thermal stability and can withstand temperatures as high as 260°C, which enables the normal operation of the cable to be maintained in an extremely high temperature environment. As a coating layer of the cable core, the first polytetrafluoroethylene tape 5 has good electrical insulation, corrosion resistance, high temperature resistance and low friction coefficient; it can effectively protect the twisted wire pairs and prevent corrosion and damage to the twisted wire pairs by the external environment, thereby improving the strength of the wire; at the same time, the low dielectric constant and dielectric loss of the first polytetrafluoroethylene tape help reduce the attenuation of the signal during transmission and improve the signal transmission effect;

[0037] Filling the gaps in the cable core with Kevlar reinforcement ribs 4 can further enhance the strength of the cable; the Kevlar reinforcement ribs 4 can effectively resist tensile and compressive forces, thereby improving the overall strength of the communication cable.

[0038] The Teflon insulation layer 2 is arranged on the outside of the conductor 1, which can not only provide good electrical insulation performance, but also maintain a stable insulation effect in a high temperature environment; the high temperature resistance and excellent electrical performance of the Teflon insulation layer 2 help to reduce interference and attenuation in cable signal transmission, thereby enhancing the signal transmission effect and also enhancing its overall strength;

[0039] To sum up, a first polytetrafluoroethylene tape 5 is provided on the outside of the twisted wire pair 3 to form a cable core, and the gap of the cable core is filled with Kevlar reinforcement ribs 4. The twisted wire pair 3 includes: at least two communication line groups, and the communication line group includes: a conductor 1, and a Teflon insulation layer 2 is provided on the outside of the conductor 1. This structure not only improves the wire strength of the communication cable, but also enhances the signal transmission effect of the communication cable.

[0040] Preferably, the conductor 1 comprises: a silver-plated silver-copper alloy wire (not shown) and a Kevlar wire (not shown), wherein the silver-plated silver-copper alloy wire (not shown) and the Kevlar wire (not shown) are twisted together to form the conductor 1;

[0041] Silver-plated silver-copper alloy wire (not shown) and Kevlar wire (not shown) are interwoven to form a whole.

[0045] Preferably, the diameter of the silver-copper alloy wire (not shown) is 0.06-0.1 mm, and the thickness of the silver-plated layer (not shown) is 0.8-1.2 μm;

[0046] The diameter of the silver-copper alloy wire (not shown) is preferably 0.06-0.1 mm. Further, the diameter of the silver-copper alloy wire (not shown) is preferably 0.06 mm, 0.08 mm and 0.1 mm. Due to space limitations and for simplicity, the utility model does not exhaustively list the specific point values ​​included in the range. The silver-copper alloy wire with a smaller diameter can increase the number of conductors inside the cable, thereby increasing the conductor density of the cable. This means that more signals can be transmitted within the same cable volume, which helps to improve the efficiency and capacity of signal transmission;

[0047] The thickness of the silver-plated layer (not shown) is preferably 0.8-1.2 μm; further, the thickness of the silver-plated layer is preferably 0.8 μm, 1 μm and 1.2 μm. Due to space limitations and for the sake of simplicity, the utility model no longer exhaustively lists the specific point values ​​included in the range. The silver-plated layer is thickened to make the conductor 1 more resistant to high temperatures.

[0048] Preferably, the central gap of the cable core surrounded by the multiple twisted wire pairs 3 is filled with Kevlar reinforcement ribs 4, and the gap formed by every two adjacent twisted wire pairs 3 and the first polytetrafluoroethylene tape 5 is filled with Kevlar reinforcement ribs 4.

[0049] Preferably, the communication line groups are twisted in pairs to form twisted wire pairs 3, and the twisted wire pairs 3 have better flexibility and strength than a single wire. This structure can disperse external forces and reduce stress concentration, thereby improving the tensile strength and wear resistance of the wire.

[0050] Preferably, the outer side of the first polytetrafluoroethylene tape 5 is provided with a braided layer 6, a second polytetrafluoroethylene tape 7 and a Teflon sheath 8 in sequence from the inside to the outside;

The spring-shaped cable used in the present application has a relatively uniform stress distribution inside when subjected to external force, because the spring structure can disperse the external force to the entire cable, and it is not easy to have stress concentration and fracture of the cable;

[0056] The spring-shaped communication cable 9 for use in a high temperature environment has good elasticity and resilience. This design enables the spring-shaped communication cable 9 for use in a high temperature environment to shrink or stretch when needed, thereby reducing the space occupied when not in use; at the same time, due to its unique shape, the spring-shaped communication cable 9 for use in a high temperature environment is also easier to manage and stack during transportation and storage.
