Embodiment
Illustrate content of the present invention below in conjunction with accompanying drawing 1～5 and embodiment.
Novel aviation cable protective jacket 30 provided by the invention is formed by monofilament 3 braidings, described monofilament 3 is take aramid fiber bundle 1 as heart yearn, twine silver-plated copper flat filament line 2 outward, described aramid fiber bundle 1, be PPTA, the preferred industrial aramid fiber long filament of 420dtex (1dtex is the diameter that this fiber material of 1g pulls into the silk of the long even thickness of ten thousand metres, and 420dtex is that the aramid fiber that a synnema is 1.5dtex by 420 every thicknesses forms); In the preferred embodiment of the present invention, the line density of aramid fiber bundle 1 used (dtex) is 448, fracture strength (CN/dtex) is 19.1, elongation at break (%) 2.47; The ultimate strength CV(% of described silver-plated copper flat filament line 2) be 2.39, elongation at break (%) is 3.24.
Fig. 1 is the looping process schematic diagram that monofilament is used in Novel aviation cable protective jacket braiding of the present invention, adopt high-speed wrapping machine, under the rotating speed of 30000 rev/mins, aramid fiber bundle 1 and silver-plated copper flat filament line 2 are revolved to twist with the fingers mutually be wound in monofilament, silver-plated copper flat filament line 2 specifications are 0.17mm * 0.05mm, and the 100mm wire is wound around number of times 120～130, winding direction to the right, finished product external diameter 0.25mm～0.29mm, weight is not more than 0.12g/m, twines wrap angle sigma=tg
-1h
/π (D+d); H is the pitch that is wrapped (mm), and D is aramid fiber bundle 1 external diameter approximation (mm), and d is silver-plated copper flat filament line 2 external diameter approximations (mm); In monofilament 3 braiding processes, aramid fiber bundle 1 must not have any distortion, must not twist, and silver-plated copper flat filament line 2 wants tight looping on aramid fiber bundle 1, and the looping pitch is even, and silver-plated copper flat filament line 2 must not fracture, arch camber, loose or knotting, damage etc.
Fig. 2 is Novel aviation cable protecting jacket structure schematic diagram of the present invention, can see the A-A cross section monofilament situation of arranging; Fig. 5 is Novel aviation cable protective jacket weaving parameter list of the present invention, press product requirement and formulate weaving, monofilament 3 has been compiled into certain density with identical rule of arranging, have the Novel aviation cable protective jacket of 2 * 4,3 * 6,6 * 10,24 * 32 4 kinds of specifications, the weaving parameter as shown in Figure 5.
Fig. 4 is that Novel aviation cable protective jacket of the present invention uses view, Fig. 3 is traditional metal protective jacket partial cables assembly schematic diagram, and wherein 10 is adapters, the 20th, and the metal protection cover, compare with the traditional metal protective jacket, Novel aviation cable protective jacket advantage of the present invention is as follows:
First, quality gently makes novel cable be superior to other engine cables, need between the traditional metal protective jacket to realize cable branch with metal adaptor 10, and novel cable as shown in Figure 4 cable branch realize with the wrapping line, the crust of whole cable all need not the intervention of metal object, and then having alleviated the weight of engine, the novel cable assembly is 72% of metal protection cover cable assembly weight.
The second, good assembling, the Novel aviation cable protective jacket is very soft, can be arbitrarily crooked, thereby can be crooked fixing flexibly in the process of making cable, have more flexibility.
The 3rd, core has more the repetition maintainability, and the bifurcation of metal protection cover cable has adapter 10, and the wire core is kept in adapter, will take adapter in maintenance process apart and could use the surplus core, causes inconvenient maintenance; Novel cable employing wrapping line is branch fixedly, and quality is soft, and length requirement is loose, its core and two directly is contained in cable, and neither impact assembling can needn't be decomposed cable again when maintenance, directly place under repair at the cable branch place, and can repeat to repair, so maintainability is strong.
The above is only preferred embodiment of the present invention, is not to limit application range of the present invention; All other do not break away from the equivalence of completing under disclosed essence and change or modify, and all should be included in following claims scope.
