The aerospace cable has the advantages of simple structure, flexibility, light weight, high tensile strength and high electromagnetic pulse resistance, simultaneously and comprehensively has effects of power transmission, signal transmission and data transmission, and can normally work in a flame.
Description
Technical field
The invention belongs to technical field of electric wires and cables, particularly relate to a kind of Aero-Space cable.
Background technology
Cable for aerospace need under the prerequisite meeting basic purposes weight as far as possible light, be applied in fighter plane some easily by the electric wire hitting fire location require around on fire be subject to pullling more greatly stress simultaneously when still there is normal energising, communication (digital signal, analog signal) function.
Each root cable of Aero-Space has oneself corresponding weight and volume, be applied to its quality of cable in aeronautical and space technology service system and volume has certain restriction, thus make the quantity of cable also need to be limited, thus find comprehensive bunch of cables, can effectively solve cable space and weight issue.And along with the raising of people's environmental consciousness and the quickening of Chinese society economic construction paces, low-smoke halogen-free inflaming-retarding cable is widely used in each important department and public place.When a fire, during cable fire, do not discharge corrosive gas, and light transmission is good, is very helpful, can reduces casualties and property loss to a great extent to rescue work.Now need to develop a kind of composite cable, not only make wiring easily, can ensure cable-flame retardant, low temperature resistant, anti-oxidant, soft, environmental protection simultaneously, take up room little, collection data wire and holding wire are integrally, easy to install.
Summary of the invention
Main purpose of the present invention is the deficiency overcoming above-mentioned technology, and provides a kind of Aero-Space cable.Cable weight is light, and can be subject to power of pullling and normally use under playing fire environment.
The present invention for achieving the above object, by the following technical solutions: a kind of Aero-Space cable, it is characterized in that: comprise polyethylene fibre central core and be stranded in the wire harness outside described polyethylene fibre central core successively, at stranded fill gaps aramid fiber, be provided with F4/ polyimide composite film, aramid fiber layer, conductive fabric belt, F4/ polyimide composite film outward again at the intertwist body of described polyethylene fibre central core, wire harness, aramid fiber composition.
Preferably, semiconductive ceramic SiClx rubber layer is provided with between described conductive fabric belt and F4/ polyimide composite film.
Beneficial effect: structure of the present invention is simple, and cable is soft, lightweight, high resistance pulling force, high electromagnetic pulse-resisting, comprehensively has the effect of electric power transfer, Signal transmissions and transfer of data simultaneously, and normally can work in flame combustion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1, a kind of Aero-Space cable, comprise polyethylene fibre central core 1 and be stranded in the wire harness 2 outside described polyethylene fibre central core successively, at stranded fill gaps aramid fiber 3, be provided with F4/ polyimide composite film 4, aramid fiber layer 5, conductive fabric belt 6, semiconductive ceramic SiClx rubber layer 7, F4/ polyimide composite film 8 outward again at the intertwist body of described polyethylene fibre central core, wire harness, aramid fiber composition.
The full name of Wen Zhong: F4: polytetrafluoroethylene; The full name of F46: perfluoroethylene-propylene; The full name of F40: Ethylene/tetrafluoroethylene.
Central core adopts the high-modulus linear polyethylene fiber of lay configuration, described intertwist body adopts the high-modulus aramid fiber dredged around structure outward, for the main supporting course of this composite cable, described stranded space adopts high-modulus linear polyethylene fiber-filled, is the secondary supporting course of this composite cable.By the supplementary function of main supporting course two kinds of different stretch modulus material synergy and secondary supporting course, enable cable weight while bearing very high tensile stress very light.The outer aramid fiber that adopts is as the Another reason of supporting course; aramid fiber can tolerate 400 DEG C of high temperature; this cable have passed through the heat-blocking action of semiconductive ceramic silicon rubber when standing flame combustion; therefore aramid fiber still has extraordinary tensile property; aramid fiber layer has certain heat-blocking action simultaneously; together with semiconductive ceramic SiClx rubber layer, F4/ polyimide composite film layer; cut off the temperature that extraneous flame combustion produces, protection high-modulus polyethylene fibres and the intertwist body around it.
Protective layer outside intertwist body is wrapped F4/ polyimide composite film successively, and dredge around aramid fiber, wrapped conduction strap, extrudes semiconductive ceramic SiClx rubber, wrapped F4/ polyimide composite film composition.Wrapped and sintering after F4/ polyimide composite film there is fabulous corona-resistance property and high and low temperature resistance, environment and proof stress performance, can play a good protection; Conduction strap and semiconductive ceramic silicone rubber belt are worked in coordination with, and all have good shielding electricity, magnetic action at high frequency and low frequency, overcome simultaneously alloy strip that common high resistance magnetoelectricity cable generally applies as electro-magnetic screen layer make cable weight greatly, defect that hardness is too high; Semiconductive ceramic SiClx rubber both provided shielding action with conduction strap is collaborative, and can become ceramic body when flame combustion again, play and stop flame combustion and heat insulation effect, cable can normally work completely in flame combustion.
Structure of the present invention is simple, and cable is soft, lightweight, high resistance pulling force, high electromagnetic pulse-resisting, comprehensively has the effect of electric power transfer, Signal transmissions and transfer of data simultaneously, and normally can work in flame combustion.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
