Abstract
Disclosed in the utility model 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
The utility model relates to cable, relates in particular to Aero-Space fluoroplastic insulation lightweight cable.
Background technology
Along with the development of China Aviation aerospace industry, the aircraft of more and more models develops, and is widely used as cable electric and that electronic equipment connection is used.Due to the particularity of Aviation cable environment for use, conventionally need cable to there is the performances such as excellent resistance to high energy electron irradiation, high-low temperature resistant impact, corrosion-resistant, chemically-resistant solution.Space flight and aviation cable product is taking GJB/ 773A-2000 " Aero-Space fluoropolymer insulated wire cable " as foundation at present, simultaneously with reference to U.S. army mark MIL-W-22759 " MILITARY SPECIFICATION SHEET " standard, but cable still has very large defect at aspect of performances such as flexibility, high temperature resistant, fire-retardant and radiation proofs.This product is to formulate according to user's particular/special requirement, take into full account its applicability and reliability, has solved the instructions for use under the particular surroundingss such as performance such as flexibility, high temperature resistant, fire-retardant and radiation proof.
Utility model content
For overcoming above-mentioned deficiency, the utility model object is to provide Aero-Space fluoroplastic insulation lightweight cable.
Scheme of the present utility model is as follows: Aero-Space fluoroplastic insulation lightweight cable, it is made up of conductor wire core, round conductor woven shield, fluoroplastic insulation layer and external sheath layer, and described conductor wire core is to be extruded on silver-gilt copper wire stranded conductor and to be formed by silicone rubber insulation layer; Described three conductor wire cores are twisted into cable core; Described cable core gap-fill has fire-retardant gasket for packing, and cable core is provided with round conductor woven shield outward; Described external sheath layer and fluoroplastic insulation layer cover on round conductor woven shield successively from outside to inside.
Described round conductor woven shield adopts proof copper-wire braided and copper strips is wrapped combines.
Described fluoroplastic insulation layer and external sheath layer all adopt cross-linking radiation ethylene-tetrafluoroethylene copolymer material.
The beneficial effects of the utility model: the utility model structural design is simple, stable performance, can meet the performance requirement of cable for aerospace, and high temperature resistant, fire-retardant and radiation-resistant feature, and cable softness, lightweight are easy to lay.
