Abstract

The utility model discloses an entity color bar encoded insulating wire. The entity color bar encoded insulating wire is characterized in that: on the cross section of the wire, the outermost layer rubber sleeve sub-areas are set to be sectorial entity areas with different colors; and the sectorial entity areas with different colors are helical in the axial direction of the wire to form helical color bars on the peripheral surface of the wire. The color bars of the wire cannot be stripped off, and have accurate color codes and a large number of variable codes.

Description

The insulated electric conductor of entity vitta coding

Technical field

The utility model relates to the colour coding electric wire, makes the colour coding electric wire of high-density wiring 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, for example: shown in Figure 1, the primary colours body 11 of white is set in the appearance of conductor wire core 10, spaced surface at the primary colours body of white 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.

The utility model content

The utility model is for avoiding above-mentioned existing in prior technology weak point, the 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 being provided.

The design feature of the insulated electric conductor of the utility model entity vitta coding 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 the utility model entity vitta coding also is:

In described electric wire periphery helical form vitta, the primary colours body is set is white, be the twice of other vitta width as the white entity area of primary colours body.

Described electric wire periphery helical form vitta is the rotation of left-hand axle.

Compared with the prior art, the utility model beneficial effect is embodied in:

1, the utility model 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 entity vitta;

2, the utility model is demarcated 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 utility model 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.
