Characterized in that the made up.

As described above, according to the electric wire for preventing moisture absorption and the manufacturing method thereof, the first core is completely wrapped by the first insulator, and the second core of the outer periphery is completely wrapped by the second insulator. As a result, a structure in which moisture is hardly absorbed is obtained. Therefore, it is possible to prevent various malfunctions and failures due to moisture absorption in all wiring systems using such wires.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings such that those skilled in the art may easily implement the present invention.

Referring to FIG. 3A, there is shown a perspective view in which the insulator is partially peeled off from the wire for preventing water absorption according to the present invention. Referring to FIG. 3B, a cross-sectional view along the line b-b of FIG.

As shown, the electric wire according to the present invention includes a first core 11, a plurality of second cores 12, a first insulator 13, and a second insulator 14.

First, the first core 11 may be a conventional copper wire.

The plurality of second cores 12 are positioned at the outer circumference of the first core 11, and the material may be the copper wire as described above. In addition, eight second cores 12 are illustrated in the drawings, but the present invention is not limited thereto.

The first insulator 13 completely surrounds the first core 11. In addition, the first insulator 13 may completely wrap some of the plurality of second cores 12 and partially wrap the first insulator 13. The reason for this shape is that a plurality of second cores 12 are pressed onto the first insulator 13 during the manufacturing process. Here, the first insulator 13 may be silicon or equivalent thereof, but the material of the first insulator 13 is not limited thereto.

The second insulator 14 surrounds the entire exposed second core line 12 and the first insulator 13. Therefore, since the first core 11 and the second core 12 are both completely enclosed by the first insulator 13 or the second insulator 14, there is no absorption path of moisture. Meanwhile, the second insulator 14 may be a polymer or an equivalent thereof, but the material of the second insulator 14 is not limited thereto.

4, there is shown a cross-sectional view of the wire manufacturing apparatus for preventing moisture absorption according to the present invention.

As shown in the drawing, the wire manufacturing apparatus according to the present invention includes a coating part 20, a first crimping part 31, a second crimping part 32, and a third crimping part 33.

The coating part 20 coats and discharges a first insulator 13 such as silicon on the first core 11, which is a copper wire. That is, as the first core 11 passes through the coating unit 20, the first insulator 13 is naturally coated on the first core 11. Naturally, the first core 11 may be pulled at a constant speed at the right end of the figure.

The first crimping part 31 is positioned in a substantially funnel shape at the rear end of the coating part 20, which compresses and discharges the first insulator 13 to the first core line 11. That is, since the passage is narrower toward the end of the first crimping portion 31, the first insulator 13 is naturally compressed to the first core 11 passing therethrough.

The second crimping portion 32 is located in a substantially funnel shape on the outer circumference of the first crimping portion 31. In addition, a core wire supply passage 34 is formed between the first crimping portion 31 and the second crimping portion 32 to supply the second core wire 12, which is a plurality of copper wires. The second crimping portion 32 supplies the second core 12 to the surface of the first insulator 13 and simultaneously compresses the second core 12 to the first insulator 13 to the outside. Discharge. That is, since the passage is narrower toward the end of the second crimping portion 32, the second core 12 is pressed against the first insulator 13 passing therethrough. Here, the second core 12 may be slightly inserted or partially inserted into the first insulator 13 although it varies slightly depending on the end diameter of the second crimping portion 32. In addition, although the baby is natural, the first core line 11 and the second core line 12 may be pulled at a predetermined speed from the right end of the figure.

The third crimping portion 33 is located in a substantially funnel shape on the outer circumference of the second crimping portion 32. In addition, a plurality of insulator supply passages 35 are formed between the second crimping portion 32 and the third crimping portion 33 to supply the second insulator 14 such as a polymer. The third crimp unit 33 compresses and discharges the second insulator 14 to the first insulator 13 and the second core 12. That is, the passage is narrower toward the end of the third crimping portion 33, so that the second insulator 14 is pressed against the first insulator 13 and the second core 12 passing therethrough. Therefore, according to the electric wire manufacturing apparatus according to the present invention, the first core 11 is completely enclosed by the first insulator 13, and the first insulator 13 and the plurality of second cores 12 are again made. By being completely wrapped by the insulator 14, it is possible to manufacture an electric wire without an absorption path of moisture.

Subsequently, in the pressing of the plurality of second cores 12 on the first insulator 13, the second cores 12 are inserted such that the plurality of second cores 12 are inserted into the first insulator 13. ). Here, some of the second core 12 may be completely inserted into the first insulator 13, and some of the second core 12 may be partially inserted into the first insulator 13. Of course, the second core 12 may be completely inserted into the first insulator 13 and may be shorted to the first core 11, but the first core 11 and the second core 12 may be equipotential. Because of the flow of electricity, there is no problem in achieving the electrical function even if they are shorted to each other. (Third state in the drawing)

Finally, in the step of compressing the second insulator 14 on the surfaces of the second core 12 and the first insulator 13, a portion of the second core 12 and the first insulator (exposed to the outside) A second insulator 14, such as a polymer, is pressed onto the surface of (13).

Therefore, the first core 11 and the second core 12 are both completely enclosed by the first insulator 13 or the second insulator 14, thereby producing a wire having no water absorption path. .
