본 발명은 전력케이블의 케이블 도체(1)가 연결되는 접속부(4) 및 케이블의 애관(5)을 커버하는 잠금부(3)가 일체형 구조로 형성된 도체 인출봉(2)과, 케이블의 애관(5)의 외부로 노출된 상태로 상기 도체 인출봉(2)의 접속부(4)에 연결된 케이블 도체(1)로 구성되는 특징이 있다.The present invention provides a conductor drawing rod (2) in which the connecting portion (4) to which the cable conductor (1) of the power cable is connected, and the locking portion (3) covering the conduit (5) of the cable are integrally formed, and the conduit of the cable ( 5) is characterized in that it consists of a cable conductor (1) connected to the connecting portion (4) of the conductor withdrawing rod (2) in the state exposed to the outside.

도면과 실시예를 참조하여 본 발명을 상세하게 설명한다.The present invention will be described in detail with reference to the drawings and examples.

도 1은 종래의 도체 인출 구조의 구성도이고 도 2는 본 발명에 의한 실링 겸용 일체형 도체 인출 구조의 구성도이다.1 is a configuration diagram of a conventional conductor drawing structure, and FIG. 2 is a configuration diagram of a sealing combined integrated conductor drawing structure according to the present invention.

종단 접속함의 내부에 케이블의 애관(5)을 커버하는 원반 형상의 잠금부(3)와 일체형 구조로 이루어진 일정한 길이의 도체 인출봉(2)이 형성된다. 상기 도체 인출봉(2)의 잠금부(3)측 단부에는 케이블 도체(1)가 접속되는 접속부(4)가 형성되며 타측 단부는 종단 접속함 외부로 인출되어 가공선, 차단기, 변압기 등과 연결된다. 상기 접속부(4)는 케이블 도체(1)를 압착하여 견고하게 고정할 수 있도록 충분한 깊이를 지녀야 하고, 접속부(4)의 단면적은 케이블 도체(1)와의 접촉 저항에 의한 발열을 방지하고 연결 작업시 케이블 도체(1)가 용이하게 접속되도록 케이블 도체(1)의 단면적보다 약간 크게 형성된다.Inside the terminal junction box, a conductor-drawn rod 2 of constant length is formed, which has an integral structure with a disk-shaped locking portion 3 covering the pipe 5 of the cable. The connection part 4 to which the cable conductor 1 is connected is formed at the end of the lock-out portion 3 side of the conductor lead-out rod 2, and the other end thereof is drawn out of the terminal connection box to be connected to a overhead line, a breaker, a transformer, and the like. The connecting portion 4 should have a sufficient depth to squeeze and securely secure the cable conductor 1, and the cross-sectional area of the connecting portion 4 prevents heat generation due to contact resistance with the cable conductor 1 and at the time of connection work. It is formed slightly larger than the cross-sectional area of the cable conductor 1 so that the cable conductor 1 can be easily connected.

원반 형상인 잠금부(3)에서 애관(5)과의 접촉면에는 애관(5) 내부의충진재(6)가 팽창될 경우 충진재(6)의 누설을 방지하도록 원형 형상의 홈이 형성되고 상기 홈의 내부에 O-링 형태의 실링재(7)가 형성된다.A circular groove is formed in the disc-shaped locking part 3 to prevent leakage of the filler 6 when the filler 6 inside the annular tube 5 is expanded on the contact surface with the annular tube 5. The sealing material 7 in the form of an O-ring is formed therein.

종단 접속함의 내부에서 도체 인출봉(2)과 인접한 위치에 전력케이블의 단부가 형성된다. 상기 케이블의 도체(1)의 단부는 애관(5)의 외부로 일정 길이만큼 노출되며, 상기 애관(5)의 내부에는 일정 분량의 충진재(6)가 충진된다.An end of the power cable is formed at a position adjacent to the conductor lead-out rod 2 in the termination box. An end portion of the conductor 1 of the cable is exposed to the outside of the pipe 5 by a predetermined length, and a certain amount of filler 6 is filled in the inside of the pipe 5.

상기와 같이 애관(5)의 외부로 노출된 케이블 도체(1) 및 도체 인출봉(2)의 접속부(4)가 접속되고, 상기 접속부(4)가 압착기에 의하여 케이블 도체(1)로 압착됨으로서 도체 인출봉(2) 및 케이블 도체(1)가 서로 연결된다. 도체 인출봉(2) 및 케이블 도체(1)의 연결 작업이 애관(5)의 외부에서 이루어지므로 도체 인출봉(2) 및 케이블 도체(1)의 접속 작업과 압착기에 의한 압착 작업이 매우 용이하다.As described above, the cable conductor 1 exposed to the outside of the conduit 5 and the connection portion 4 of the conductor lead-out rod 2 are connected, and the connection portion 4 is compressed into the cable conductor 1 by a crimping machine. The conductor drawing rod 2 and the cable conductor 1 are connected to each other. Since the connection work of the conductor lead-out rod 2 and the cable conductor 1 is performed outside the conduit 5, the connection work of the conductor lead-out rod 2 and the cable conductor 1 and the crimping operation by the press are very easy. .

상기한 연결 작업을 수행하면 도체 인출봉(2)과 일체화된 잠금부(3)가 케이블의 애관(5)을 커버하게 된다. 즉 도체 인출봉(2) 및 케이블 도체(1)의 연결 작업과 애관(5)의 커버 작업이 동시에 진행된다.When the above connection operation is performed, the locking portion 3 integrated with the conductor drawing rod 2 covers the cuff 5 of the cable. In other words, the connection work of the conductor drawing bar 2 and the cable conductor 1 and the cover work of the love pipe 5 proceed simultaneously.

애관(5) 내부에 충진된 충진재(6)는 애관(5)을 커버한 원반 형상의 잠금부(3)에 의하여 애관(5) 외부로 유실되는 것이 방지된다. 어떤 이유로 충진재(6)가 팽창될 경우 잠금부(3)에 형성된 실링재(7)에 의하여 충진재(6)가 유출되는 것이 방지된다.The filler 6 filled in the pipe 5 is prevented from being lost to the outside of the pipe 5 by the disk-shaped locking part 3 covering the pipe 5. If for some reason the filler 6 is expanded, the filler 6 is prevented from leaking out by the sealing material 7 formed in the lock 3.

본 발명에 의한 실링 겸용 일체형 도체 인출 구조는 실링재가 형성된 잠금부와 일체형 구조를 이루는 도체 인출봉 및 애관의 외부로 노출된 케이블 도체가 접속 및 압착되어 연결된 구조로서 부품수가 크게 감소되어 구조가 매우 간단하고 재료비가 적게 소요되며, 도체 인출봉 및 케이블 도체가 애관의 외부에서 연결되고 애관의 커버 작업이 상기 연결 작업과 동시에 진행되므로 연결 작업이 용이하여 작업 효율이 향상된다.The integrated double conductor withdrawal structure according to the present invention is a structure in which the conductor withdrawing rod and the cable conductor exposed to the outside of the pipe are connected and crimped together to form an integral structure with a locking part formed with a sealing material. The material cost is low, and the conductor withdrawing rod and the cable conductor are connected from the outside of the pipe and the cover work of the pipe is carried out at the same time as the connection.
