The body (10) is a tubular body having an external shape and has a jacket pressing portion for pressing the covering portion of the electric wire so as not to move, and a pressing portion composed of a nonconductor while pressing the electric conductor portion And a diaphragm 300 formed at a central position between the protrusions 400 and the body 10 and made of a conductor and connected to a conductor of the wire to transmit electricity.

그리고 결합플랜지(100)에서 90°회전된 만큼 이격되어 몸체 외측에 다수의 연결플랜지(200)가 구비되어 송배전용 전선연결 접속장치(1)를 전주에 연결된 고정대상체(2)에 고정할 수 있도록 하였다.A plurality of connection flanges 200 are provided on the outer side of the body so as to be spaced apart from each other by 90 degrees in the coupling flange 100 so that the electric connection connecting device 1 for transmission and distribution can be fixed to the fixed object 2 connected to the electric pole. Respectively.

그리고 전선연결 접속장치 내부 중앙에는 격판(300)을 구비하여 연결할 전선이 중앙의 격판을 기점으로 좌우에서 동일하게 전선연결 접속장치 내에 삽입될 수 있도록 하였다.In addition, a diaphragm 300 is provided at the center of the wire connection and connection device so that the wires to be connected can be inserted into the wire connection and connection device from the center diaphragm starting from the left and right.

또한, 전선연결 접속장치 내부에는 다수의 가압돌부(400)를 구비하여 전선을 연결할 때 전선을 가압하여 전선이 전선연결 접속장치 내부에서 이탈하는 것을 방지할 수 있도록 하였다. In addition, a plurality of pressing protrusions 400 are provided in the wire connecting and disconnection device to press the wires when connecting the wires so as to prevent the wires from being separated from the wire connecting and disconnection device.

이에 따라 한쌍으로 이루어진 반원형상의 몸체(10)는 결합플랜지(100)를 이용하여 체결하되 전선이 삽입될 수 있도록 여유를 두고 체결한다. Accordingly, the pair of semicircular bodies 10 are tightened using the coupling flange 100 with sufficient clearance so that the wires can be inserted.

이후 연결하고자 하는 전선은 끝단의 피복을 제거하여 도체부가 노출된 상태에서 전선연결 접속장치(1)의 양측으로부터 각각 삽입한다.Then, the wires to be connected are removed from both ends of the wire connecting and disconnecting device 1 with the conductor portions exposed.

이때 양측에서 삽입되는 각각의 전선의 일단은 전선연결 접속장치 내부 중앙에 구비된 격판(300)에 의해 좌우에서 동일한 길이로 전선연결 접속장치 내에 삽입된다. 또한, 도체로 이루어진 격판(300)은 전선의 도체부와 접속하여 전기가 흐르게 된다. At this time, one end of each electric wire inserted from both sides is inserted into the electric wire connecting and disconnecting device from the left and right by the diaphragm 300 provided in the center of the electric wire connecting and disconnection device. Further, the diaphragm 300 made of a conductor is electrically connected to the conductor portion of the electric wire.

이후 한쌍으로 이루어진 반원형상의 몸체를 좀 더 강하게 체결하면 전선연결 접속장치 내부에 다수 구비된 가압돌부(400)가 전선을 가압하여 전선이 전선연결 접속장치 내부에서 이탈하는 것을 방지한다.When the semicircular body of one pair is tightened more strongly, a plurality of pressing protrusions 400 provided inside the wire connection and connection device presses the wires to prevent the wires from being detached from the wire connection and connection device.

이후 송배전용 전선연결 접속장치(1)의 외측에 피복제(500)를 상하부에서 체결한다.Thereafter, the replica 500 is fastened at the upper and lower portions to the outside of the wire connection and connection device 1 for transmission and distribution.

이후 결합플랜지(100)와 90°방향으로 이격되도록 다수 구비된 연결플랜지(200)를 이용하여 송배전용 전선연결 접속장치(1)를 전주에 연결된 고정대상체(2)에 고정한다.Thereafter, the wire connecting and disconnecting device for transmission and distribution 1 is fixed to the stationary object 2 connected to the electric pole using a plurality of connection flanges 200 spaced apart from the joint flange 100 in the direction of 90 degrees.

상기와 같은 구성의 본 발명은 전선을 연결할 때 전선을 가압하여 연결함으로써 연결상태가 안정되게 유지되고 전선의 연결 작업시 작업능률을 크게 향상시키며 작업시간을 크게 줄이면서 유비보수 비용을 절감시키는 장점이 있다.
