Problems solved by technology

However, at present, the cable insulation used in transmission cables in aerospace and other fields is thick, bulky, heavy, and the insulation is easily cracked and aged after being subjected to high-energy electron radiation in outer space, and has poor safety and reliability in high-temperature environments.
Therefore, the existing aviation cables can no longer meet the requirements of aerospace products in the direction of miniaturization, light weight, and high reliability.

Embodiment Construction

[0014] Such as figure 1 as shown, figure 1 It is a structural schematic diagram of an extrusion-resistant and high-temperature-resistant multifunctional cable for aviation proposed by the present invention.

[0015] refer to figure 1 , an extrusion-resistant and high-temperature-resistant multifunctional cable for aviation proposed by the present invention, including a cable core, a wrapping layer 3, a shielding layer 4, and a sheath layer 5;

[0016] The above-mentioned cable core includes a wire 1 and four signal wires 2. The wire 1 includes an insulating support tube 11 located in the middle. The insulating support tube 11 is made of thermoplastic elastomer material. Copper wires are wound to form a conductor layer 12, thereby forming a circular cross-section. Utilizing the principle of the skin of the copper conductor, while ensuring the electrical conductivity of the cable, the amount of copper used is reduced, and the total weight of the cable is reduced. In addition, ...

Abstract

The invention discloses an extrusion-resistant high-temperature resistant multifunctional cable for aviation. A cable core comprises a lead located in the middle part; the lead comprises an insulating support pipe, a conductor layer, a first insulating layer and an epoxy resin coating from inside to outside; signal lines with arc-shaped sections are uniformly distributed around the lead; each signal line internally comprises multiple signal bodies which are parallel and spaced mutually, and the axial lines of the signal bodies are located at the same arc-shaped surface; a second insulating layer is extruded on the outer parts of all the signal bodies of each signal line. The extrusion-resistant high-temperature resistant multifunctional cable for aviation disclosed by the invention is light in weight, compact in structure, extrusion-resistant and good in high-temperature resistant performance.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an extrusion-resistant and high-temperature-resistant multifunctional cable for aviation. Background technique [0002] With the development of aerospace technology, the requirements for the safety performance, radiation resistance, insulation performance and volume weight of the wire and cable wiring system in the aircraft are getting higher and higher. However, at present, the cable insulation used in transmission cables in aerospace and other fields is thick, bulky, and heavy, and the insulation is easily cracked and aged after being exposed to high-energy electron radiation in outer space, and has poor safety and reliability in high-temperature environments. Therefore, the existing aviation cables can no longer meet the requirements of the development of aerospace products in the direction of miniaturization, light weight and high reliability. [0003] In particular, in the e...
