Accompanying drawing explanation
Fig. 1 is the cross-sectional structural representation of the winding lead of the utility model embodiment.
Mark in figure: 1 is conductor wire core; 2 is screen; 3 is oversheath; 4 is metal wire; 5 is aramid fiber yarn; 6 is the first insulating barrier; 7 is the second insulating barrier.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, be the cross-sectional structural representation of winding lead of the utility model embodiment.Winding lead comprises the many conductor wire cores twisted together 1, the screen 2 of wrapped conductor wire core 1 and the oversheath 3 of lapped shielding layer 2.Conductor wire core 1 comprises by many wires 4 and stranded conductor, the first insulating barrier 6 of wrapped conductor and the second insulating barrier 7 of wrapped first insulating barrier 6 of Duo Gen aramid fiber yarn 5.Aramid fiber yarn 5 is filled in the space of many wires 4.The diameter of the relative aramid fiber yarn 5 of diameter of metal wire 4 is comparatively large, enough in the space of therefore many wires 4 fills aramid fiber yarn 5 equably.In the present embodiment, metal wire is the one in tinned wird, silver-coated copper wire, nickel plated copper wire, silver-plated copper alloy line and nickel-clad copper alloy wire, and be preferably silver-coated copper wire, the material of aramid fiber yarn is aramid fiber 1313 or Fanglun l414.The quantity of conductor wire core 1 can be arranged according to actual needs, is set to 4 in the present embodiment, and 4 conductor wire cores 1 by predetermined strand to concentric stranding, that is, 4 conductor wire cores 1 arrange around the circumferencial direction of same axial line.After aramid fiber yarn 5 carried secretly by metal wire 4, structure is strengthened, thus had concurrently excellent electric and mechanical performance.
Screen 2 is woven by silver-plated copper coating aluminum magnesium silk and forms, and the external diameter of silver-plated copper coating aluminum magnesium silk is 0.1mm ~ 0.25mm.Oversheath 3 is polytetrafluoroethylraw raw material band, and the rate of putting up of raw material band is 50.5% ~ 54%.
First insulating barrier 6 is the composite band of polytetrafluoroethylene and polyimides, and the second insulating barrier 7 is polytetrafluoroethylraw raw material band, and the rate of putting up of composite band and raw material band is 50.5% ~ 54%.
Because conductor wire core 1 has dielectric layers 6,7 and screen 2 and oversheath 3, there is high temperature resistant, low temperature resistant, resistant to hydrolysis, opposing chemical corrosion, the advantages such as radiation resistance is superior.
When making winding lead, can many wires 4 be carried secretly many aramid fiber yarns 5 and be twisted into conductor, wrapped sintering first insulating barrier 6 and the second insulating barrier 7 obtain conductor wire core 1 successively again, and after many conductor wire core 1 strandings, braiding obtains screen 2, more wrapped sintering oversheath 3.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
