[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The utility model provides Figure 1-3 A composite high temperature resistant cable is shown, comprising a plurality of conductor harnesses 1, a stabilizing layer 2 arranged outside the conductor harnesses 1, and a protective cover 3 arranged outside the stabilizing layer 2:

[0028] A heat-resistant layer 4 is further provided between the protective cover 3 and the stabilizing layer 2. The heat-resistant layer 4 includes an outer layer 41 connected to the inner wall of the protective cover 3, an inner layer 42 wrapped around the outer side of the stabilizing layer 2, and a middle layer 43 provided between the outer layer 41 and the inner layer 42.

[0029] The outer layer 41 is a polyphenylene ether layer, the middle layer 43 is a glass fiber layer, and the inner layer 42 is a silicone rubber layer.

[0030] In one embodiment, the protective cover 3 is configured as a polyvinyl chloride layer, which has excellent chemical stability and corrosion resistance, and is not easy to burn, preventing the cable from being hot-melted or producing open flames, and has good safety performance. The stabilizing layer 2 is configured as a galvanized steel belt braided layer with a tight structure, which can further effectively reduce the influence of external forces and improve the overall tensile resistance of the cable.

[0031] In one embodiment, a shielding layer 5 is further provided inside the stabilizing layer 2, a filling layer 6 is provided inside the shielding layer 5, several strands of the conductor harness 1 are provided inside the filling layer 6, and an insulating layer 7 is wrapped on the outside of each strand of the conductor harness 1, the shielding layer 5 is provided as an aluminum foil braided layer, which can effectively isolate the magnetic field generated when the wire harness transmits current, thereby ensuring the normal use of the conductor harness 1, the filling layer 6 is provided as an aramid yarn interlaced layer, and the aramid yarn filling satisfies the various transverse and longitudinal compression and torsional properties of the isolation frame, thereby improving the overall torsional resistance of the cable, the insulating layer 7 is provided as a polyethylene layer, which can isolate the circuit, and cooperate with the heat-resistant layer 4 to provide high-temperature protection for the conductor harness 1.

[0032] In one embodiment, the conductor harness 1 is provided with four strands, and a base frame 8 is provided between the four strands of the conductor harness 1, the base frame 8 is provided in a cross shape, and the four ends of the base frame 8 are respectively connected to the outer layers 41 of the four insulating layers 7, and the base frame 8 is provided as a steel bar. The base frame 8 can provide support for the conductor harness, so that the cable as a whole is more solid, can resist external mechanical shock and vibration, and reduce damage. The base frame 8 is provided as a steel bar to provide the cable with anti-tensile properties, so that the cable is more stable when in use.

[0033] The specific implementation mode is as follows: when the utility model is used, the protective cover 3 made of a polyvinyl chloride layer is provided, so that the cable is not easy to burn when in use and has flame retardant performance. When the cable is used in a high temperature environment, the setting of the heat-resistant layer 4 improves the high temperature resistance of the cable, so that the cable can be used in a high temperature environment, has high adaptability, and avoids the safety hazard of skin cracking.

[0034] Specifically, the outer layer 41 made of the polyphenylene ether layer can be used in a high temperature environment, has excellent high temperature resistance, and can block the external heat from being transferred to the conductor harness 1. The middle layer 43 woven from the glass fiber layer also has good high temperature resistance, which can further prevent the external heat from damaging the conductor harness 1. The glass fiber layer can also provide a layer of physical protection for the conductor harness 1, so that the conductor harness 1 has a certain tensile resistance. At the same time, the inner layer 42 made of the silicone rubber layer has good flexibility and strong adaptability to temperature fluctuations, which can further block the heat from being transferred to the conductor harness. The conductor harness 1 is transmitted, and the excellent flexibility can protect the conductor harness 1 when it is bent for use. Therefore, the outer layer 41 made of the polyphenylene ether layer, the middle layer 43 made of the glass fiber layer, and the inner layer 42 made of the silicone rubber are spliced ​​together to form a heat-resistant layer 4, which not only improves the overall performance of the cable, but also provides all-round protection for the cable as a whole. The high-temperature resistance is strengthened layer by layer, and the external heat is not easy to be transmitted to the conductor harness 1, which effectively reduces the influence of high temperature on the conductor harness 1, so that the conductor harness 1 can be used at extreme temperatures, so that the cable has excellent high-temperature resistance;

[0035] This implementation specifically solves the problem in the prior art that the high temperature resistance of the composite cables is generally poor when in use, and when the cables are in a high temperature environment, their surface is prone to cracking, causing safety hazards.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
