Embodiment Construction

[0010] The present invention will be further described below in conjunction with accompanying drawing;

[0011] Such as figure 1 As shown, the fluoroplastic insulated light cable for aerospace is composed of a conductive core 1, a round conductor braided shielding layer 5, a fluoroplastic insulating layer 6 and an outer sheath layer 7. The conductive core 1 is made of silicone rubber The insulation layer 3 is extruded on the silver-plated copper wire stranded conductor 2; the three conductive wire cores 1 are stranded to form a cable core; the gap between the cable core is filled with a flame-retardant filling rope 4, and a round conductor is arranged outside the cable core The braided shielding layer 5; the outer sheath layer 7 and the fluoroplastic insulating layer 6 cover the round conductor braided shielding layer 5 sequentially from outside to inside.

[0012] The round conductor braided shielding layer 5 is formed by braiding copper wire and wrapping copper tape.

Abstract

Disclosed in the invention is a fluoroplastic insulation light cable for aerospace. The cable is formed by conductive cores, a circular conductor braiding shielding layer, a fluoroplastic insulation layer, and an outer sheath layer. Silver-plated copper wire stranded conductors are extruded by silicone rubber insulation layers to form the conductive cores; and the three conductive cores are stranded to form a cable core. The gap of the cable core is filled with a flame-retardant filling rope; the circular conductor braiding shielding layer is arranged outside the cable core; and the outer sheath layer and the fluoroplastic insulation layer successively cover the circular conductor braiding shielding layer from the outside to inside. According to the scheme, the provided cable has advantages of simple structure design, and stable performance; and the performance requirement of the cable for aerospace can be met. The provided cable has characteristics of high temperature resistance, inflaming retarding, radiation prevention, flexibility, light weight, and easy laying.

Description

technical field [0001] The invention relates to cables, in particular to fluoroplastic insulated light cables for aerospace. Background technique [0002] With the development of China's aerospace industry, more and more types of aircraft are being developed, and they are widely used as cables for connecting electrical and electronic equipment. Due to the particularity of the environment in which aviation cables are used, cables are usually required to have excellent resistance to high-energy electron radiation, high and low temperature impact resistance, corrosion resistance, and chemical solution resistance. At present, aerospace cable products are based on GJB / 773A-2000 "Fluoropolymer Insulated Wires and Cables for Aerospace" and refer to the US military standard MIL-W-22759 "MILITARY SPECIFICATION SHEET". Performance aspects such as high temperature resistance, flame retardancy and radiation protection still have great defects. This product is formulated according to ...
