The preparation method is characterized in that an outermost layer rubber jacket is set as fan-shaped entity zones with different colors in a zoning mode on the cross section of a wire; and the fan-shaped entity zones with the different colors are helical in the axial direction of the wire so as to form helical color bars at the periphery of the wire. The color bars of the invention can not drop and has exact color code and large coding capacity; and the preparation method of the invention is simple and reliable and has high production efficiency.
Description
Technical field
The present invention relates to colour coding electric wire and preparation method thereof, make colour coding electric wire of high-density wiring and preparation method thereof in a kind of electronic engineering that is mainly used in aerospace field of more specifically saying so.
Background technology
The colour coding electric wire is the high-grade product in the electric wire field, and this series products is mainly used in the electronic engineering of aerospace field.
The wiring zone point-score that uses at present a large amount of high-density wiring engineerings has: the one, in electric wire surface spray printing sign; The 2nd, at electric wire two ends suit sign sleeve pipe; The 3rd, electric wire adopts different colours to distinguish.But there is following shortcoming in these differentiating methods:
1, electric wire surface spray printing sign in use is worn easily, and external diameter is difficult to the spray printing sign less than the electric wire of 1mm, and the fluoroplastic insulation electric wire can't be in surperficial spray printing sign;
2, electric wire two ends suit sign sleeve pipe owing to the sign sleeve pipe has occupied certain space, forces between electric wire and the electric wire and strengthen at interval, so wiring density is limited, does not identify inconvenient actual installation and maintenance in addition at other positions of electric wire;
3, electric wire adopts color not to distinguish to comprise with the color of monochrome and distinguishes and distinguish at the surface applied vitta: in order to improve the monochromatic definition of distinguishing, adopt 10 kinds of monochromes usually, see the following form;
Color and colour coding
| Color | Black | Palm fibre | Red | Orange | Yellow | Green | Blue | Purple | Ash | In vain |
| Colour coding | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
Differentiating method as for surface applied vitta color, in insulated the easily influence of primary colours of the vitta of electric wire surface applied, in addition, because technology and equipment does not also have ability to ensure that vitta abuts against with vitta now, what therefore adopt is coating at interval, as shown in Figure 1, periphery at conductor wire core 10, spaced surface in white base 11 applies blue vitta 12 and red vitta 13, but when colour code is represented with colour coding, this 9 kind 9692,6929,9296,2969 (four positional representations), 962,926,629,296,269 (three positional representations) colour coding all is correct, has therefore caused sign chaotic.
Unite States Standard MIL-STD-681D is in order to get rid of the influence of primary colours to vitta, white is decided to be primary colours, and the regulation basic stimulus is listed as the 1st in colour coding is represented, and does not repeat, the vitta colour coding can only be arranged in order from small to large, and therefore colour coding shown in Figure 1 is 926.But this has just limited the colour coding total amount, and for example the colour coding of three bit representations has only 36 kinds.
Because the coating vitta is to arrange along the electric wire axially parallel, therefore when wiring, be difficult to see all vittas on full electric wire surface, and its vitta adhesive force is bad, installs and uses in the process to come off easily in addition.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, insulated electric conductor of the entity vitta coding that a kind of vitta can not come off, colour coding accurate, the codified amount is big and preparation method thereof being provided.
The design feature of the insulated electric conductor of entity vitta coding of the present invention is: on the cross section of electric wire, outermost layer gum cover subregion is set to the fan-shaped entity area of different colours; The fan-shaped entity area of described different colours forms the helical form vitta of electric wire outer surface at the axially shape in the shape of a spiral of electric wire.
The design feature of the insulated electric conductor of entity vitta coding of the present invention also is:
In the helical form vitta of described electric wire outer surface, be the twice of other vitta width as the white entity area of primary colours body.
The helical form vitta of described electric wire outer surface is the rotation of left-hand axle.
The preparation method's of the insulated electric conductor of entity vitta coding of the present invention characteristics are to carry out according to the following procedure:
A, each chromoresin of the fan-shaped entity area of different colours in the outermost layer gum cover is added in the preformation type tube repressed tubular insulation base by setting regions;
B, employing are pushed equipment cable core are extruded line base just with the insulation base; Described line base just becomes the line base through high temperature sintering; Subsequently, the line base is cooled to normal temperature;
C, the line base adopted at normal temperatures add the machine of turning round and reverse, make the vitta curl on line base surface by the lay ratio of setting, the helix base; With described helix base by high-temperature shaping, again through the natural cooling colour coding electric wire that gets product.
Preparation method's of the present invention characteristics are that also described outer gum cover is to be material with the polyflon, in the described step 2 first line base being become the sintering temperature of line base through high temperature sintering is 200 ℃～380 ℃, high-temperature shaping temperature in the step 3 is 150～400 ℃, and fixing time is 3～5 minutes.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention is provided with the entity vitta, has avoided the influence of primary colours to other vitta, and each road vitta can be arranged continuously, need be with the primary colours body as the interval; There is not the problem that comes off because of wearing and tearing in the body colour bar in fact;
2, the present invention demarcates initial code with the primary colours body of different in width, need not to limit colour coding size arrangement mode, the colour coding reading of helical form vitta has uniqueness, has improved the colour coding total amount greatly, double-colored sign indicating number can have 90, three look colour codings to have 720, has increased the colour coding total amount greatly.
3, the present invention is provided with electric wire periphery helical form vitta and is the rotation of left-hand axle, makes electric wire can both know identification electric wire colour coding in any position and direction.
4, preparation method of the present invention is simple, reliable, the production efficiency height.
