Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a high-temperature resistant signal transmission cable. Background Art

[0002] In many fields such as modern industry, aerospace, and automobile manufacturing, the stability and reliability of signal transmission are crucial. However, in some special working environments, such as high temperature and high wear, traditional signal transmission cables often cannot meet the requirements.

[0003] In high-temperature environments, the insulation materials of ordinary cables are prone to aging, deformation, or even melting, resulting in signal transmission interruption or failure. At the same time, in some environments with wear and tear such as friction and scratching, the cable sheath is easily damaged, so improvements are needed. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that cables are prone to aging, deformation or even melting in a high-temperature environment, and to propose a high-temperature resistant signal transmission cable.

[0005] In order to achieve the above-mentioned objectives, the utility model adopts the following technical solution: a high-temperature resistant signal transmission cable, comprising a cable core, an insulating layer fixedly installed on the outer wall of the cable core, a mica tape wrapping layer fixedly installed on the outer wall of the insulating layer, a shielding layer fixedly installed on the outer wall of the mica tape wrapping layer, an aerogel insulation layer fixedly installed on the outer wall of the shielding layer, a high-temperature resistant layer fixedly installed on the outer wall of the aerogel insulation layer, a ceramic fiber layer fixedly installed on the outer wall of the high-temperature resistant layer, a wear-resistant layer fixedly installed on the outer wall of the ceramic fiber layer, a reinforcing layer fixedly installed on the outer wall of the wear-resistant layer, and an outer sheath layer fixedly installed on the outer wall of the reinforcing layer.

[0006] Preferably, the cable core is made of a highly conductive metal material such as copper or aluminum, and the insulation layer is made of a high-temperature resistant insulating material such as polytetrafluoroethylene or cross-linked polyethylene. The cable core, made of a highly conductive metal material such as copper or aluminum, is responsible for transmitting electrical signals. Copper and aluminum have excellent electrical conductivity, ensuring efficient signal transmission. The insulation layer, made of a high-temperature resistant insulating material such as polytetrafluoroethylene or cross-linked polyethylene, is wrapped around the cable core to provide insulation and prevent current leakage and signal interference.

[0007] Preferably, the mica tape wrapping layer is made of mica sheets bonded to a substrate such as glass fiber cloth or polyester film via an adhesive such as a high-temperature resistant silicone resin, and the shielding layer is a metal braided mesh woven from copper wire or tinned copper wire. Here, the mica tape wrapping layer, which is made of mica sheets bonded to a substrate such as glass fiber cloth or polyester film via an adhesive such as a high-temperature resistant silicone resin, has high-temperature and corona resistance properties, and can prevent the occurrence of corona discharge while preventing external high-temperature air, dust, etc. from entering the interior of the cable, thereby protecting the internal signal transmission structure. The shielding layer of the metal braided mesh woven from copper wire or tinned copper wire can reduce the impact of external electromagnetic interference on signal transmission. The metal braided mesh can effectively reflect and absorb electromagnetic radiation, thereby ensuring the stability of signal transmission.

[0008] Preferably, the aerogel insulation layer is made of a nanoporous material such as silica aerogel encapsulated in a carrier material such as fiber felt or polymer film, and the high-temperature resistant layer is made of a high-performance material such as ceramic silicone rubber or polyimide. Here, the aerogel insulation layer, which is made of a nanoporous material such as silica aerogel encapsulated in a carrier material such as fiber felt or polymer film, has an extremely low thermal conductivity coefficient. It can effectively prevent heat transfer, isolate heat outside the cable, and protect the internal signal transmission structure from high temperature. The high-temperature resistant layer, made of high-performance materials such as ceramic silicone rubber or polyimide, can maintain the structural stability and performance of the cable in high-temperature environments. These materials have excellent high-temperature resistance and can withstand the test of high-temperature environments.

[0009] Preferably, the wear-resistant layer is made of a wear-resistant material such as nitrile rubber or polyurethane, and the reinforcement layer is made of a high-strength material such as steel wire or aramid fiber. The wear-resistant layer acts as a buffer and isolation layer, reducing friction between the internal structure and the outer sheath, enhancing the overall structural stability of the cable and indirectly protecting the outer sheath. The reinforcement layer, made of a high-strength material such as steel wire or aramid fiber, improves the mechanical strength of the cable and prevents damage from stretching, bending, and other conditions.

[0010] Preferably, the outer sheath layer is made of chloroprene rubber or low-smoke halogen-free polyolefin, etc. Here, the outer sheath layer made of chloroprene rubber or low-smoke halogen-free polyolefin, etc., can protect the internal structure of the cable and has certain high temperature resistance and wear resistance.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] In the utility model, through the synergistic effect of specific materials in each layer, the cable can effectively prevent heat transfer and aging and deformation in a high-temperature environment, and adapt to harsh working conditions. At the same time, through the design of wear-resistant materials, the service life of the cable is improved. This design meets the strict requirements of modern industry, aerospace, automobile manufacturing and other fields for signal transmission cables in special environments, and provides a strong guarantee for carrying out signal transmission work.
