종단접속재는 가공과 지중이 만나는 부분에 설치하는 접속재이다. The end connection material is a connection material that is installed in the area where the processing and the underground meet.

종단접속재가 주로 사용되는 부분은 한전 배전선로(가공과 지중이 만나는 곳)와 고객 책임 분계점 이후(가공으로 전기를 공급받아 지중으로 구내에 전기를 공급하는 곳)에 주로 사용한다.Termination materials are mainly used for distribution lines of KEPCO (where processing meets the ground) and after the customer responsibility threshold (where electricity is supplied through processing and supplies electricity to the premises through the ground).

이러한 종단접속재는 도체단부가 가공전선의 도체단부와 결합볼트를 통해 단순 체결된다.In such a termination material, the conductor end is simply fastened through the conductor end of the overhead wire and the coupling bolt.

다시 말해서 결합볼트가 종단접속재의 도체단부와 가공전선의 도체단부를 관통하여 결합너트와 체결됨에 따라 전기적으로 연결된다.In other words, as the coupling bolt penetrates the conductor end of the termination member and the conductor end of the overhead wire and is fastened with the coupling nut, it is electrically connected.

그런데, 도 1에 도시된 것처럼 시공 완료후 시간이 경과함에 따라 결합볼트와 결합너트 사이가 풀리게 되고, 이에 따라 종단접속재의 도체단부와 가공전선의 도체단부 사이가 비틀어지게 되며, 종단접속재의 도체단부와 가공전선의 도체단부 사이에 이격으로 인한 접촉불량으로 과열 현상이 발생하는 문제점이 있었다.However, as shown in Fig. 1, as time elapses after construction is completed, the connection between the coupling bolt and the coupling nut is loosened, and accordingly, the conductor end of the termination member and the conductor end of the overhead wire are twisted, and the conductor end of the termination member There is a problem that overheating occurs due to poor contact between the and the conductor end of the overhead wire.

또한, 겨울에 수축하고 여름에 팽창함을 반복하면서 결합볼트와 결합너트 사이가 이격되어 접촉불량이 발생하는 문제점이 있었다.In addition, while contracting in winter and expanding in summer repeatedly, there is a problem in that contact failure occurs due to separation between the coupling bolt and the coupling nut.

또한, 도 2에 도시된 것처럼, 시공시 결합볼트와 결합너트를 작업자가 일일이 조립함에 따라 느슨하게 체결되거나 2개의 결합볼트 중 어느 한쪽에는 와셔가 조립되고 나머지 한쪽에는 와셔가 누락되는 등의 시공불량이 발생하고, 시공불량 부위에서 종단접속재의 도체단부와 가공전선의 도체단부 사이에 이격으로 인해 과열 현상이 발생하는 문제점이 있었다.In addition, as shown in Figure 2, as the operator assembles the coupling bolt and the coupling nut one by one during construction, it is loosely fastened or a washer is assembled to one of the two coupling bolts, and a washer is omitted at the other. There is a problem that overheating occurs due to the separation between the conductor end of the termination material and the conductor end of the overhead wire at the site of poor construction.

The twist between the and the second compression connection 220 is prevented.

이러한 돌출부(130)는 제1압착접속부(120)에 다양한 형태로 하나 또는 복수 개로 구비될 수 있으며, 일예로 도면에 도시된 것처럼 제1압착접속부(120)의 폭방향의 가운데 부분에서 돌출되어 길이방향으로 형성될 수 있다.One or more of these protrusions 130 may be provided in various forms on the first crimp connection unit 120, and as an example, as shown in the drawing, the protrusion 130 protrudes from the middle portion in the width direction of the first crimp connection unit 120 It can be formed in any direction.

또한, 돌출부(130)의 돌출된 단부가 제1압착접속부(120)의 제2압착접속부(220)와 맞닿는 면과 평행한 평면으로 형성되며 돌출부(130)의 양측면이 수직한 평면으로 형성되어, 돌출부(130)의 돌출된 단부와 양측면이 오목부(230)의 내측면에 지지된다.In addition, the protruding end of the protruding portion 130 is formed in a plane parallel to the surface abutting the second compression connecting portion 220 of the first compression connecting portion 120 and both sides of the protruding portion 130 are formed in a vertical plane, The protruding ends and both side surfaces of the protruding portion 130 are supported on the inner surface of the concave portion 230.

또한, 도 5 내지 도 6에 도시된 것처럼, 제1도체터미널(100)과 제2도체터미널(200)은 제1압착접속부(120)와 제2압착접속부(220) 사이가 이격되지 않도록 돌출부(140)와 오목부(240)의 형상으로 한번 체결되고, 결합유닛(300)으로 한번더 체결되는 이중체결 구조로 마련될 수도 있다.In addition, as shown in Figs. 5 to 6, the first conductor terminal 100 and the second conductor terminal 200 have a protrusion ( 140) and the concave portion 240 is fastened once in the shape, and may be provided in a double fastening structure that is fastened once more with the coupling unit 300.

이러한 돌출부(140)는 돌출된 단부로 갈수록 폭이 넓어지게 형성된다.The protrusion 140 is formed to have a wider width toward the protruding end.

그리고, 오목부(240)는 돌출부(140)와 대응되는 형상으로 제2압착접속부(220)에 함몰되게 형성되되 제2압착접속부(220)의 길이방향의 단부 측으로 개구되도록 형성되며, 개구된 부분을 통해 돌출부(140)가 끼움 결합된다.In addition, the concave portion 240 is formed to be recessed in the second compression connection portion 220 in a shape corresponding to the protrusion portion 140 and is formed to be opened toward the end side in the longitudinal direction of the second compression connection portion 220, and the opened portion Through the protrusion 140 is fitted.

즉, 돌출부(140)의 양측면이 경사면으로 형성되는데 경사면과 제1압착접속부(120) 사이에 공간이 형성되게 하는 경사면으로 형성되며, 경사면과 제1압착접속부(120) 사이의 공간에 제2압착접속부(220)가 삽입된다.That is, both sides of the protrusion 140 are formed as an inclined surface, which is formed as an inclined surface that allows a space to be formed between the inclined surface and the first compression connection 120, and the second compression is applied to the space between the inclined surface and the first compression connection 120 The connection part 220 is inserted.

오목부(240)의 양쪽 내측면도 경사면으로 형성되는데 양쪽 내측면에서 삼각돌기가 돌출 형성되게 하는 경사면으로 형성되어 돌출부(140)의 경사면에 맞닿는다.Both inner surfaces of the concave portion 240 are also formed as inclined surfaces, and are formed as inclined surfaces for protruding triangular protrusions from both inner surfaces to contact the inclined surface of the protrusion 140.

이에 따라 돌출부(140)의 경사면과 제1압착접속부(120) 사이의 공간에 오목부(240)의 양쪽 내측면의 삼각돌기가 삽입되고, 돌출부(140)의 경사면과 오목부(240)의 경사면이 맞닿아 서로 지지되어 가체결된다. 그리고 결합유닛(300)을 통해 한번더 체결된다.Accordingly, triangular protrusions on both inner surfaces of the concave part 240 are inserted into the space between the inclined surface of the protruding part 140 and the first compression connection part 120, and the inclined surface of the protruding part 140 and the inclined surface of the concave part 240 They come into contact and are supported and temporarily fastened.
