[0002] In fields such as optical fiber communication cables, automotive equipment, railway tracks, military industry, shipbuilding and locomotive manufacturing, as well as general industrial manufacturing, there are wires that require double protection. During operation, equipment often experiences high-frequency or large-amplitude vibrations. During these vibrations, the wire harness can easily rub against the contacting equipment. Prolonged friction can damage the wire harness and cause equipment malfunctions. To protect the cables, braided mesh is used for wiring, so that the internal cables will not be damaged during vibrations, thus providing protection.

[0003] Traditional PET braided tubing only has basic protective functions and has significant shortcomings in flame retardancy, antistatic properties, wear resistance, and heat insulation. It cannot cope with extreme working conditions such as high temperature, flammability, and strong electromagnetic interference, making it less practical.

[0004] In view of this, we propose a flame-retardant PET braided tubing. Utility Model Content

[0018] This utility model provides the following technical solution: Example

[0019] Please refer to Figure 1-4 A flame-retardant PET braided tubing, comprising: The braided tube body 1 has a connector seat 2 fixedly installed on the left side, a connector head 3 fixedly installed on one side of the connector seat 2, an internal thread 4 fixedly installed on the inner wall of the connector head 3, a connector seat 5 fixedly installed on the right side of the braided tube body 1, a connector head 6 fixedly installed on one side of the connector seat 5, an external thread 7 fixedly installed on the outer wall of the connector head 6, and several reinforcing ribs 8 fixedly installed inside the braided tube body 1. A performance enhancement component is located inside the braided tube body 1 and is used to enhance the performance of the braided tube body 1.

[0020] The wire is inserted into the braided tube body 1 through the connector 3, and the entire device is installed together by the internal thread 4 in the connector 3 and the external thread 7 on the connector 6, thus completing the connection of the whole device. The reinforcing ribs 8 are set to evenly distribute the load and avoid local stress concentration, thereby improving the compressive strength and tensile strength of the braided tube body 1, protecting the internal wire, and thus extending its service life. The performance enhancement components ensure that the braided tube body 1 has multiple functions such as flame retardancy, wear resistance, antistatic properties, heat insulation, and basic protection, providing comprehensive protection for the wire from mechanical damage, static electricity hazards, high temperature effects, and fire threats, while combining high efficiency, safety, and economy.

[0021] In this embodiment, the performance enhancement component includes: The flame-retardant coating 9 has an internal abrasion-resistant woven layer 10, an internal antistatic layer 11, an internal heat insulation layer 12, and an internal PET woven base layer 13.

[0022] The braided tube body 1 is equipped with a flame-retardant coating 9, a wear-resistant braided layer 10, an antistatic layer 11, a heat insulation layer 12, and a PET braided base layer 13. This ensures that the braided tube body 1 has multiple functions such as flame retardancy, wear resistance, antistatic properties, heat insulation, and basic protection. It provides comprehensive protection for the wire from mechanical damage, static electricity hazards, high temperature effects, and fire threats, while also being efficient, safe, and economical.

[0023] In this embodiment, the flame-retardant coating 9, the wear-resistant braided layer 10, the antistatic layer 11, the heat insulation layer 12, and the PET braided base layer 13 are bonded together with adhesive.

[0024] The flame-retardant coating 9, the wear-resistant woven layer 10, the antistatic layer 11, the heat insulation layer 12, and the PET woven base layer 13 are bonded together using the provided adhesive.

[0025] In this embodiment, the flame-retardant coating 9 is made of melamine cyanurate, and the thickness of the flame-retardant coating 9 is 5μm-10μm, and the thickness of the wear-resistant woven layer 10 is 0.1mm-0.5mm.

[0026] Among them, the flame-retardant coating 9, made of melamine cyanurate, can slow down the spread of flames or even self-extinguish when a fire occurs around the wire or when it comes into contact with an open flame, thus preventing the fire from spreading. The wear-resistant braided layer 10, made of PET and aramid fiber, can withstand high-intensity friction when the wire passes through the braided tube body 1 or needs to move frequently, preventing the outer layer of the wire from being worn through. At the same time, the high strength of the aramid fiber allows the braided layer to resist the puncture of sharp objects, preventing the wire from exposing the internal conductor due to mechanical damage and reducing the risk of short circuits or leakage.

[0027] In this embodiment, the antistatic layer 11 is made of metal fiber coated with an antistatic agent, and the thickness of the antistatic layer 11 is 30μm-50μm. The heat insulation layer 12 is made of glass fiber cotton, and the thickness of the heat insulation layer 12 is 0.5mm-1mm.

[0028] Among them, the antistatic layer 11 is made of metal fiber coated with antistatic agent. During the use of the wire, especially in high-speed movement or friction scenarios, the antistatic layer 11 can conduct away the static electricity generated on the surface of the wire in time, avoiding electrostatic discharge from damaging precision electronic components. The heat insulation layer 12 is made of glass fiber cotton. When there is a high temperature source around the wire, the glass fiber cotton can effectively block the heat transfer to the wire, prevent the wire insulation layer from aging and melting due to high temperature, and avoid the risk of short circuit. The porous structure of glass fiber cotton has a certain degree of elasticity, which can absorb the impact of external vibration on the wire and reduce the breakage of the internal conductor or the damage to the insulation layer caused by vibration.

[0029] In this embodiment, the PET woven base layer 13 is made of polyethylene terephthalate, and the thickness of the PET woven base layer 13 is 0.5mm-1mm.

[0030] Among them, the PET braided base layer 13 is made of polyethylene terephthalate and serves as the bottom structure of the braided tube. It forms a mesh skeleton through warp and weft weaving, providing basic shape support for the wire and preventing the wire from deforming due to external pressure or bending. PET itself is wear-resistant, oil-resistant, and solvent-resistant, and can block minor external friction and scratches, preventing the outer layer of the wire from directly contacting sharp objects or rough surfaces.

[0031] In this embodiment, connector 1 2 and connector 2 5 are symmetrically arranged about the center line of the braided tube body 1.

[0032] The symmetrical arrangement of connector 1 (2) and connector 2 (5) ensures uniform stress on the braided tube body 1, preventing loose connections, leaks, or structural damage due to installation misalignment. It also facilitates standardized production and interchangeability, improving installation efficiency and operational stability.

[0033] In actual operation, when this device is used, the wire is inserted from connector 3 into the braided tube body 1, and then the entire device is installed together by using the internal thread 4 in connector 3 and the external thread 7 on connector 6, thereby completing the connection of the whole device. The reinforcing ribs 8 are set to evenly distribute the load and avoid local stress concentration, thereby improving the compressive strength and tensile strength of the braided tube body 1, protecting the internal wire, and thus extending its service life. The flame-retardant coating 9, made of melamine cyanurate, slows the spread of flames and can even self-extinguish when a fire occurs around the wire or it comes into contact with an open flame, preventing the fire from spreading. The wear-resistant braided layer 10, made of PET and aramid fibers, withstands high-intensity friction when the wire passes through the braided tube 1 or needs frequent movement, preventing the outer layer of the wire from being worn through. The high strength of the aramid fibers also allows the braided layer to resist punctures from sharp objects, preventing mechanical damage that could expose the internal conductors and reducing the risk of short circuits or leakage. The antistatic layer 11, made of metal fibers coated with an antistatic agent, effectively conducts static electricity generated on the wire surface during use, especially in high-speed movement or friction scenarios, preventing electrostatic discharge from damaging precision electronic components. Finally, the heat insulation layer 12, made of fiberglass wool, can effectively conduct static electricity generated on the wire surface during use, especially in high-speed movement or friction scenarios, preventing damage to precision electronic components from electrostatic discharge. When a high-temperature source exists around the wire, the fiberglass wool can effectively block heat transfer to the wire, preventing the insulation layer from aging and melting due to high temperatures, thus avoiding the risk of short circuits. The porous structure of the fiberglass wool has a certain degree of elasticity, which can absorb the impact of external vibrations on the wire, reducing the risk of internal conductor breakage or insulation layer damage caused by vibration. The PET braided base layer 13, made of polyethylene terephthalate, serves as the bottom layer structure of the braided tube. Through warp and weft weaving, a mesh skeleton is formed, providing basic shape support for the wire and preventing deformation due to external pressure or bending. PET itself is wear-resistant, oil-resistant, and solvent-resistant, and can block minor external friction and scratches, preventing the outer layer of the wire from directly contacting sharp objects or rough surfaces. Through the above devices, the braided tube body 1 is ensured to have multiple functions such as flame retardancy, wear resistance, antistatic properties, heat insulation, and basic protection, providing comprehensive protection for the wire from mechanical damage, static electricity hazards, high temperature effects, and fire threats, combining high efficiency, safety, and economy.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
