Description
Technical field：
It the utility model is related to Aero-Space cable, more particularly to a kind of microlight-type cable for Aero-Space.
Background technology：
With the rapid development of aerospace field, the use to electric wire it is also proposed higher requirement.Except satisfaction
Outside requirement on electric performance, also to meet small volume, in light weight, high mechanical strength, high reliability, high temperature resistant, resistance to various space flight and aviation
With the requirement of the extremely complicated all kinds of adverse circumstances of oil.
In aerospace field, the emphasis of cable weight Aerospace Products concern always, loss of weight is also always aviation boat
The eternal theme of its industry.
The existing general silver-coated copper wire of Aero-Space cable causes the loss of weight of cable as conductor, the physical attribute of Copper base material
Almost cannot.
Utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of microlight-type electricity for Aero-Space
Cable, the requirement of Aero-Space is met, there is number of bends that is in light weight, soft, being amenable to be several times as much as existing cable etc.
Feature.
The technical solution of the utility model is as follows：
Microlight-type cable for Aero-Space, it is characterised in that including conductor, conductor uses silver-plated carbon nano-tube fibre
Or silver-plated aramid fiber is twisted bunchy and formed, ultra-low density polyethylene insulating barrier, screen layer, sintering insulated is coated with outside conductor successively
Layer, ethylene-tetrafluoroethylene copolymer external sheath layer.
The described microlight-type cable for Aero-Space, it is characterised in that described conductor uses more CNTs
Fiber or silver-plated aramid fiber are formed according to regular bundle strand.
The described microlight-type cable for Aero-Space, it is characterised in that described screen layer uses double-decker, its
Middle internal layer uses silver-gilt copper wire woven shield using silver-plated copper band lapped shielding layer, outer layer.
The described microlight-type cable for Aero-Space, it is characterised in that described sintering insulated layer is FP-carbon fluorine
Compound condensate/polyimides/wrapped the composition of FP- fluorocarbon polymer composite bands, cap rate are not less than 60%.
The utility model has the advantages that：
The utility model novel in structural design, conductor are twisted bunchy structure using silver-plated carbon nano-tube fibre or silver-plated aramid fiber
Into having rationally designed the construction of cable according to the demand of aerospace system use environment, met the use of aerospace system
It is required that effectively reduce cable overall weight on the basis of the requirement of other aerospace applications is ensured.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Embodiment：
Referring to accompanying drawing：
For the microlight-type cable of Aero-Space, including conductor 1, conductor 1 uses silver-plated carbon nano-tube fibre or silver-plated virtue
Synthetic fibre is twisted bunchy and formed, and ultra-low density polyethylene insulating barrier 2, screen layer, sintering insulated layer 5, second are coated with successively outside conductor 1
Alkene-TFE copolymer external sheath layer 6.
Conductor 1 is formed using more carbon nano-tube fibres or silver-plated aramid fiber according to regular bundle strand, the weight of conductor after stranding
For the conductor of Copper base material and alloy base material, weight declines as obvious.
Screen layer uses double-decker, and wherein internal layer uses silver-gilt copper wire using silver-plated copper band lapped shielding layer 3, outer layer 4
Woven shield.
Sintering insulated layer 5 is FP- fluorocarbon polymers/polyimides/FP- fluorocarbon polymer composite bands
Wrapped composition, cap rate are not less than 60%.
The utility model uses external insulation structure, and wherein external insulation is sintering insulated layer 5, be distributed in screen layer periphery,
In ethylene-tetrafluoroethylene copolymer external sheath layer 6, the electrical insulation capability of cable cabling is improved, meanwhile, match with inner insulating layer 3
Close and use, with excellent electrical property outside also with high mechanical strength and creep resistance performance after stranding.
