Abstract
The utility model relates to a heat-resistant, wear-resistant, compound, insulated, and light-duty flexible wire used for space flight and aviation. The flexible wire is characterized in that the flexible wire comprises an inner conductor made up of multistrand strands of silver-coated copper wires in a twisted bundle, wherein a layer of polytetrafluoroethylene film insulation layer and a layer of polyimide/ F 46 laminated film cover layer are lapped in sequence outside the inner conductor. The flexible wire has the characteristics that because the cover layer of the conducting wire adopts lapped polyimide/ F 46 laminated film, the wearing resistance of the conducting wire is improved, and the conducting wire has the traits of softness and radiation resistance, thereby being suitable for the flight environment of space flight and aviation.
Description
Technical field
The utility model relates to a kind of space flight and aviation with the light-duty flexible cord of high temperature resistant, wear-resisting compound inslation.
Background technology
The wrapped type insulated flexible cord of China all adopts polytetrafluoroethylene film at present, because this film resistance to wear is relatively poor, only is applicable in the environment that fixedly lays.In aircraft, because electric wire vibration environment of living in, friction is unavoidable between the lead, so lead should have resistance to wear.
Summary of the invention
In view of the deficiency that prior art exists, the utility model provides a kind of space flight and aviation with the light-duty flexible cord of high temperature resistant, wear-resisting compound inslation.
The utility model for achieving the above object, the technical scheme of being taked is a kind of space flight and aviation with the light-duty flexible cord of high temperature resistant, wear-resisting compound inslation, it is characterized in that: comprise by the stranded bunchy of multiply silver-coated copper wire constituting inner wire wrapped successively one deck polytetrafluoroethylene film insulating barrier, wrapped one deck polyimides/F46 laminated film sheath outside inner wire.
Characteristics of the present utility model are: because the sheath of lead adopts wrapped polyimides/F46 laminated film, the lead resistance to wear is improved, and possess softness, radiotolerant characteristic, be applicable to the Aero-Space flight environment of vehicle.
Description of drawings
Fig. 1 is the utility model cross section structure schematic diagram and as Figure of abstract.
Embodiment
As shown in Figure 1, space flight and aviation is with the light-duty flexible cord of high temperature resistant, wear-resisting compound inslation, comprise by the stranded bunchy of multiply silver-coated copper wire constituting inner wire 1, inner wire 1 outside wrapped one deck polytetrafluoroethylene film insulating barrier 2, outside insulating barrier 2 wrapped again one deck polyimides/F46 laminated film sheath 3.
Claims (1)
