도 1 및 도 3을 참조하면, 본 실시 예에 따른 전선의 방수처리방법은 접속단자(20)에 결합되는 전선(10)의 일단부에 수지를 적출하는 적출단계(S100)와, 전선(10)의 내부 공기를 감압시켜 적출된 수지를 전선(10)의 내부로 침투시키는 감압단계(S200) 및 감압된 전선(10)의 내부 압력을 대기압으로 유지시킨 후 전선(10)의 내부로 공기를 공급하여 가압하는 압축단계(S300)를 포함한다.1 and 3, the waterproofing method of the electric wire according to the present embodiment includes an extraction step (S100) of extracting resin at one end of the electric wire 10 coupled to the connection terminal 20, and the electric wire 10. After decompressing the internal air of the () to infiltrate the extracted resin into the interior of the wire (10) (S200) and to maintain the internal pressure of the reduced pressure wire (10) to atmospheric pressure and air to the inside of the wire (10) It includes a compression step (S300) for supplying and pressing.

수지를 적출하는 적출단계(S100)에서는 공기압 조절부(130)를 통해 용기(110)의 내부로 압축공기를 주입하여 접속단자(20)와 전선(10)의 연결부위에 수지를 일정량 적출한다.In the extraction step (S100) of extracting the resin, compressed air is injected into the container 110 through the pneumatic pressure control unit 130 to extract a predetermined amount of resin at the connection portion between the connection terminal 20 and the wire 10.

감압단계(S200)에서는 공기압 조절부(130)를 통해 전선(10)의 내부 공기를 외부로 배출시켜 전선(10)의 내부를 감압한다(S210). 그러면, 전선(10)에 적출되어 있는 수지가 압력차에 의해 피복(13)의 내부로 흡입되면서 동선(11)과 피복(13) 사이로 주입되어 전선(10)의 내부가 밀폐된다.In the depressurization step (S200), the inside of the wire 10 is discharged to the outside through the air pressure adjusting unit 130 to depressurize the inside of the wire 10 (S210). Then, the resin extracted from the wire 10 is sucked into the inside of the sheath 13 by the pressure difference, and is injected between the copper wire 11 and the sheath 13 to seal the inside of the electric wire 10.

그리고 공기압 측정부(150)를 통해 감압되는 전선(10) 내부의 압력을 측정하여 내부 압력이 일정압력 이하로 감압되었는가를 판단하여(S220) 전선(10)의 내부 압력이 일정압력 예를 들어 -0.05 kgf/cmㅂ 이하로 감압되었으면 계속하여 압축단계(S300)를 수행하고, 전선(10)의 내부 압력이 일정압력 예를 들어 -0.05 kgf/cmㅂ 이하로 감압되지 않으면 전선에 수지를 적출하는 단계(S100)를 수행한다.Then, by measuring the pressure inside the wire 10 to be decompressed through the air pressure measuring unit 150 to determine whether the internal pressure is reduced to a predetermined pressure or less (S220), the internal pressure of the wire 10 is a constant pressure, for example- If the pressure is reduced to 0.05 kgf / cm ㅂ or less, the compression step S300 is continued. If the internal pressure of the wire 10 is not reduced to a predetermined pressure, for example, -0.05 kgf / cm ㅂ or less, the resin is extracted from the wire. Step S100 is performed.

압축단계(S300)에서는 공기압 조절부(130)를 통해 전선(10)의 내부로 외부 공기가 유입되도록 하여 전선(10)의 내부가 대기압으로 유지되도록 한다(S310). 그리고 공기압 조절부(130)를 통해 전선(10)의 내부로 공기를 공급하여 전선(10) 내 부를 압축한다(S320).In the compression step (S300) to allow the outside air to flow into the inside of the wire 10 through the air pressure control unit 130 to maintain the inside of the wire 10 at atmospheric pressure (S310). Then, the air is supplied to the inside of the wire 10 through the air pressure control unit 130 to compress the inside of the wire 10 (S320).

이후, 공기압 측정부(150)를 통해 압축되는 전선(10) 내부의 압력을 측정하여 그 내부 압력이 일정압력 이상인가를 판단하여(S330) 전선(10)의 내부 압력이 일정압력 예를 들어 1.05 kgf/cmㅂ 이상이면 전선(10)을 분리하여 탈거한다(S400).Thereafter, the pressure inside the wire 10 compressed through the air pressure measuring unit 150 is measured to determine whether the internal pressure is above a predetermined pressure (S330), and the internal pressure of the wire 10 is constant pressure, for example, 1.05. If more than kgf / cm ㅂ remove the wire 10 to remove (S400).

그리고 판단결과(S330) 전선(10)의 내부 압력이 일정압력 예를 들어 1.05 kgf/cmㅂ 미만이면 전선(10)에 수지를 적출하는 단계(S100)를 수행한다.If the internal pressure of the wire 10 is less than a predetermined pressure, for example, 1.05 kgf / cm ㅂ, the step S100 of extracting the resin from the wire 10 is performed.

상기와 같은 본 발명에 따른 전선의 방수처리방법은 전선(10)과 연결된 공기압 조절부(130)를 통해 전선(10) 내부의 공기를 감압시켜 전선(10)에 적출된 수지를 피복(13)의 내부로 흡입시키게 된다. 이로 인하여, 수지가 전선(10)의 피복(13) 내부로 일정거리 침투하면서 동선(11)과 피복(13) 사이가 수지에 의해 일정거리 완전하게 충진되므로, 전선을 완전하게 방수처리할 수 있다.Waterproofing method of the wire according to the present invention as described above 13 to cover the resin extracted to the wire 10 by reducing the air inside the wire 10 through the air pressure control unit 130 connected to the wire 10 (13) Inhaled into the body. As a result, the resin penetrates the inside of the sheath 13 of the electric wire 10 by a certain distance while the copper wire 11 and the sheath 13 are completely filled with a certain distance by the resin, so that the electric wire can be completely waterproofed. .

또한, 전선(10) 내부의 압력을 측정하여 전선(10)의 밀폐여부를 확인할 수 있으므로, 방수작업을 정확하고 빠르게 진행할 수 있다.In addition, since it is possible to check whether the wire 10 is sealed by measuring the pressure inside the wire 10, the waterproofing operation can be performed quickly and accurately.

더하여, 수지에 의해 밀폐된 즉 방수 처리된 전선(10)에 공기압 조절부(130)를 통해 그 내부로 공기를 공급하여 전선(10)의 기밀검사를 진행할 수 있으므로, 전선(10)의 방수처리 및 전선(10)의 기밀검사를 보다 빠르게 진행할 수 있다. 또한, 전선(10)의 기밀검사를 통해 전선(10)의 방수에 이상이 발생하게 되면 간편하게 방수처리 및 기밀검사를 반복적으로 진행할 수 있으므로, 전선(10)의 불량을 현저하게 줄일 수 있다.In addition, since the airtight inspection of the wire 10 can be performed by supplying air into the inside of the wire 10 sealed by the resin, that is, waterproof, through the air pressure adjusting unit 130, the waterproofing of the wire 10 is performed. And the airtight inspection of the wire 10 can proceed more quickly. In addition, if an abnormality occurs in the waterproofing of the wire 10 through the airtight inspection of the wire 10 can be repeatedly carried out simply waterproofing and airtight inspection, it is possible to significantly reduce the defect of the wire (10).
