Description

TECHNICAL FIELD [0001] The present invention relates to a method of manufacturing a shielded coating shield wire and a shielded coating shield wire using the shielded coating shield wire,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire manufacturing method, and more particularly, to a method of manufacturing a shielded coating shield wire.

In general, wiring harness used in automobiles is a wiring installed in a vehicle body for ignition, lighting, and charging of automobiles, and a plurality of individually insulated wires are covered together to form a simple and clean bundling Lt; / RTI >

Such a wiring harness is connected to various items such as an electric device, a protector, a fuse box, etc. mounted on a vehicle, and serves to supply an electric signal or power to be supplied from a control unit.

At this time, as described above, the electric wire used in the wiring harness usually has a conductor in which a current flows in the center, and surrounds the conductor with an insulator.

However, electromagnetic waves are emitted from such electric wires, and noise is generated because electromagnetic waves penetrate into electric wires from the outside.

Accordingly, shielding wires coated with an insulating layer have been developed and used to form a conductive layer for shielding on the conductor of the electric wire to prevent the noise as described above, and to reduce the dangers of the electric shock.

Such shielded wires are difficult to emit electromagnetic waves from the outside because electromagnetic waves generated from the conductor through which current flows are shielded by the conductive layer for shielding, and it is difficult for electromagnetic waves to flow from the outside into the wires.

Conventionally, twist wires or copper braided shielded wires are used as the wiring harnesses for preventing noise in a vehicle signal circuit, and shielding layers of these wires are grounded to prevent noise.

1 is a perspective view showing a structure of a conventional shielded wire.

As shown in Fig. 1, a conventional shielded electric wire 10 has a structure in which a conductive layer 3 is coated on an insulating layer 2 and an insulating layer 4 is coated thereon to reduce the risk of electric shock .

Since the conventional shielding wire having such a structure shields the electromagnetic wave by the conductive layer 3 for shielding the electromagnetic wave generated from the conductor 1 through which the current flows, electromagnetic waves are not emitted to the outside, Can be prevented from flowing into the wire.

However, in such a conventional shielded wire, since the conductive layer 3 is separately formed by using a metal material such as aluminum or copper in order to impart shielding performance to the electric wire, not only the thickness of the electric wire itself is increased, There is a problem in that the weight of the wire increases and the time required to manufacture the wire takes much time, resulting in a decrease in the production amount.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a shielding structure for shielding a wire by using paint or paint in place of a shield layer formed of a conventional metal material, And a method of manufacturing a shielded coating shield wire capable of increasing the production amount of electric wires.

Here, the first step may be such that the conductor is extruded outside the first extrusion molding machine in a state where the conductor is drawn and simultaneously an insulator is applied to the outer surface of the conductor.

In the second step, the shielding coating material may be sprayed on the outer surface of the conductor extruded to the outside of the first extrusion molding machine in a 360 ° direction by using a spray so that the conductor has shielding performance.

Also, between the second step and the third step, a heat treatment process for drying the shielding coating material coated on the outer surface of the conductor may be performed.
