Insulated wire coded by entity color bars and preparation method thereof

Abstract

The invention discloses an insulated wire coded by entity color bars and a preparation method thereof. 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 asto 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 [0001] The invention relates to a color-coded wire and a preparation method thereof, more specifically to a color-coded wire mainly used in electronic engineering in the field of aerospace for high-density wiring and a preparation method thereof. Background technique [0002] Color-coded wires are high-grade products in the wire and cable field, which are mainly used in electronic engineering in the aerospace field. [0003] At present, the wire identification methods used in a large number of high-density wiring projects are as follows: one is to print the logo on the surface of the wire; the other is to put marking sleeves on both ends of the wire; However, these methods of differentiation have the following disadvantages: [0004] 1. The printed logo on the surface of the wire is easy to be worn during use. It is difficult to print the logo on the wire with an outer diameter of less than 1mm, and it is impossible to print the logo on the surface of the fl...

AI Technical Summary

Problems solved by technology

[0004] 1. The printed logo on the surface of the wire is easy to be worn during use. It is difficult to print the logo on the wire with an outer diameter of less than 1mm, and it is impossible to print the logo on the surface of the fluorine plastic insulated wire;

[0005] 2. Both ends of the wires are equipped with marking sleeves. Since the marking sleeves occupy a certain space, the distance between the wires is forced to increase, so the wiring density is limited. In addition, there are no markings on other parts of the wires, which is inconvenient for actual installation and maintenance;

But this limits the total amount of color codes, for example, there are only 36 color codes represented by three digits

[0011] In addition, since the coated color stripes are arranged in parallel along the wire axis, it is difficult to see all the color stripes on the surface of the wire when wiring, and the color stripes have poor adhesion and are easy to fall off during installation and use.
