Embodiment 3：
With embodiment 1, the difference of embodiment 2, it is open type metal screen layer 11, the knot of open type overcoat 13
Structure, it is specifically：Open type metal screen layer 11 is by the tin-coated copper monofilament (silver-plated copper monofilament) along warp direction and along parallel side
To the sheet material that is woven into of silver-plated copper monofilament (tin-coated copper monofilament) longitude and latitude, open type overcoat 13 is by the nylon along warp direction
(or Polyamide Yarns) and the sheet material that is woven into of Polyamide Yarns (or nylon) longitude and latitude along weft direction.
It may be noted that the open type overcoat 13 of the present embodiment is compiled according to purposes is different from special material by the way that longitude and latitude is interspersed
Type is made into, or open type overcoat 13 is specially from film made of high polymer material：
The sheet material is shaped into around axially from the hollow drum and least partially overlapped of curling, to cause drum
Sheet material can be opened in the presence of external force and be enclosed on aircraft wire harness, and automatic reduction is into drum after external force is cancelled.
It may be noted that the filament diameter of the open type metal screen layer of the present embodiment is 0.15-0.3mm, preferably 0.2mm, adopt
Formed with 6 or 8 and silk braiding.When open type overcoat selects synthetic fibers (such as nylon, Polyamide Yarns), sub-thread uses
And silk and non-stranded mode weave along warp or weft direction.Nylon, the filament diameter of Polyamide Yarns depend on the circumstances, nylon,
Polyamide Yarns belongs to common knowledge, and the present embodiment no longer describes one by one.
The present embodiment can also use monofilament, the alternate craft woven open type metal screen layer of multifilament or open type protection
Layer.The open type protective layer of the present embodiment is protected to provide antiwear enhancement to aircraft wire harness, in manufacture more
Economy, and there is the characteristics of in light weight.
The present embodiment gives weaving, is specifically：
1. together with being cross-woven by 1 warp with the first parallel of 6-8 roots and silk；2. on the basis of the step 1
The first warp thread parallel that second parallel of 6-8 roots and silk has woven with step 1 is plugged together, the second parallel causes the first parallel
Crimped around central shaft.
In braiding, latitudinal braided wires have for the open type metal screen layer of the present embodiment, open type overcoat
Part of rarefaction and compact part, the part of rarefaction and compact part are separately arranged, and latitudinal braided wires include the first parallel and the second parallel, latitude
The first parallel on direction is snakelike in bending back and forth, and the second parallel is divided on latitude direction along the multiple of longitudinal extension
Line part, the connecting portion for connecting two adjacent line part ends, line part and connecting portion are interconnected to form and carry out back bending
That rolls over is snakelike, and the distance between two adjacent line parts of compact part is less than between two adjacent line parts of part of rarefaction
Distance.It is preferred that it is in the structure that part of rarefaction and compact part are separately arranged that compact part gradually becomes comb shape along latitude direction to both sides.
The preparation method of the direction of warp and weft different materials of the present embodiment, it is each that tin-coated copper monofilament, silver-plated copper monofilament can be obtained
From the advantages of, silver-plated copper shows electric conductivity mainly for increase, anti-oxidation, and tin-coated copper is mainly for anti-oxidation, convenient braiding.
More specifically, the anti-oxidation principle of silver-plated copper and silver-plated copper is different, silver-plated is because the movable metallic of silver
Weak, silver should not aoxidize than copper.Surface Creation fine and close oxide layer when tin-coated copper is then tin oxidation, so as to prevent internal continuation oxygen
Change.
Polyamide fibre (Fypro) strength, wearability are good, occupy first of all fibres.Its wearability is the 10 of cotton fiber
Times, it is 10 times of dry state viscose rayon, is 140 times of hygrometric state fiber.Therefore, its durability is splendid.Nylon fabric elasticity and
Elastic recovery is fabulous, but yielding under small external force, therefore its fabric variable fold during wearing.
Nylon is also known as nylon, be on molecular backbone containing recurring amide radical group-[NHCO]-thermoplastic resin it is total
Claim, modified nylon, after the mechanical strength for properly increasing nylon, it is possible to reach the intensity of metal material, so as to substituted metal；
Modified nylon can also improve the wearability of nylon in itself, to adapt to wear-resisting require high occasion.Therefore, the nylon of the present embodiment
It is preferred that modification of nylon.
Nylon (polyamide) is mainly used in synthetic fibers, due to polyamide have nontoxic, light, excellent mechanical strength,
Wearability and preferable corrosion resistance.Also, the advantages of polyamide is most prominent is that wearability is higher than other all fibres, compares cotton
Wearability is high 10 times, higher than wool 20 times, and some Fypros are slightly entered in blend fabric, it is wear-resisting to be greatly improved its
Property；When being stretched to 3-6%, elastic recovery rate is up to 100%；Foldings up to ten thousand time are amenable to scratch and not broken.Fypro
Intensity is higher than cotton 1-2 times, higher than wool 4-5 times, is 3 times of viscose rayon.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded
To belong to the scope of protection of the utility model.
