일반적으로 각 가정에는 외부로 부터 인입되는 전원 입력선의 배전반에 누전차단기가 설치되어 집안 내에서 누전이 발생하였을 경우에는 누전차단기의 보턴이 하측으로 작동하여 누전차단기에 의하여 외부의 전원이 차단되어 전기적으로 발생하는 불의의 사고를 미연에 방지할 수 있도록 하였으나 누전차단기가 각 가정에 인입되는 입력선의 배전반에만 공통적으토 설치되어 있으므로 집안내에서 누전이 발생하였을 경우에는 집안 내의 모든 전원이 차단되는 등의 문제점이 있었다.In general, each home has an earth leakage breaker installed in the switchboard of the power input line that is input from the outside. When an electric leakage occurs in the house, the button of the earth leakage breaker operates downward and the external power is cut off by the earth leakage breaker. Although it was possible to prevent inadvertent accidents occurring, the earth leakage breaker is installed only in the switchboard of the input line that enters each home. Therefore, when a short circuit occurs in the house guide, all the power inside the house is cut off. there was.

도면에 도시한 바와 같이, 본 발명의 콘센트는 누설 전류를 검출하는 영상 변류기(ZCT(Zero Current Transformer); 30), 미약한 누설 전류를 증폭하는 누설 전류 증폭부(40), 누설 전류의 양을 판단하여 이하 기술하는 동작부의 동작을 지시하는 판단부(50), 상기 판단부(50)에서 동작 지시를 받을 경우 플러그를 밀어 이탈시키는 기능을 하는 동작부(60)를 포함한다. 상기 동작부(60)의 핵심 기능은 플러그를 삽입할 때 스프링(64)의 기계적 힘이 축적되고, 누전이 발생되면 축적된 스프링(64)의 락이 풀리게 하여 스프링의 반발력으로 플러그를 이탈하게 하는 장치이다. 도면에서 70은 플러그이고, 71은 플러그 구멍이며, 72는 전원선이다. 동작부(60)는 누전시 자기력에 의해 이동하는 전자석(61), 상기 전자석을 밀어내는 철편(62), 누전이 안되는 정상 상태시, 걸림홈(65)에 걸려 있는 걸림부(63), 누전 차단시 플러그(70)를 플러그 구멍(71)으로부터 밀어내는 플러그 방출부(66), 상기 플러그 방출부(66)에 연결되어 있는 스프링(64)을 구비한다. 걸림부(63)의 형태는 본 발명에서는 갈고리 형태로 도시하였으나, 이에 한정되지 않으며, 여러 가지로 수정 및 변형실시될 수 있다. 걸림부(63)는 기다란 장방형의 바(63a)에 연결되어 있으며, 바(63a)는 철편(62)에 수직으로 연결되어 있다. As shown in the figure, the outlet of the present invention includes a zero current transformer (ZCT) 30 for detecting leakage current, a leakage current amplifier 40 for amplifying a weak leakage current, and an amount of leakage current. Determination unit 50 to determine the operation of the operation unit to be described below, and the operation unit 60 to function to push out the plug when receiving the operation instruction from the determination unit 50. The core function of the operation unit 60 is a device that allows the mechanical force of the spring 64 to be accumulated when the plug is inserted, and if a short circuit occurs, the lock of the accumulated spring 64 is released to release the plug by the repulsive force of the spring. to be. In the figure, 70 is a plug, 71 is a plug hole, and 72 is a power supply line. The operation unit 60 includes an electromagnet 61 which moves by magnetic force when a short circuit occurs, an iron piece 62 that pushes the electromagnet, and a stopping part 63 that is caught in the locking groove 65 in a normal state where a short circuit does not occur. It is provided with a plug discharge part 66 which pushes the plug 70 out of the plug hole 71 at the time of interruption, and a spring 64 connected to the plug discharge part 66. Although the shape of the locking portion 63 is illustrated in the form of a hook in the present invention, it is not limited thereto and may be modified and modified in various ways. The engaging portion 63 is connected to the elongated rectangular bar 63a, and the bar 63a is connected to the iron piece 62 vertically.

도 4는 본 발명의 동작부의 동작원리를 설명하는 도면이다. 4 is a view for explaining the operation principle of the operation unit of the present invention.

먼저 도 3의 누전량을 검출하는 판단부(50)가 누설전류 30mA 또는 15mA 이상 검출될 시 증폭부(40)로 신호를 전달한다. 그러면 증폭부(40)에서는 미약한 누설전류를 증폭하여 동작부(60)의 전자석(61)으로 전달한다. 그러면 전자석(61)의 철편(62)이 자기력에 의해 도 4에서 아래쪽으로 도시한 방향으로 이동하여 걸림부(63)가 걸림홈(65)에서 빠지게 된다. 그러면 스프링(64)에 의해 반발력이 작용하여 플러그(70)를 플러그 삽입 구멍으로부터 이탈시키게 되어 누전시 플러그를 자동으로 이탈시킬 수 있다. 또한 누전이 해결된 후 플러그를 삽입할 경우 플러그 이탈 버튼을 밀어넣어 다시 스프링이 복귀되고, 다시 걸림부(63)가 다시 걸림홈(65)에 걸리게 된다. First, when the determination unit 50 detecting the leakage amount of FIG. 3 detects a leakage current of 30 mA or 15 mA or more, the signal is transmitted to the amplifier 40. Then, the amplifier 40 amplifies the weak leakage current and transfers it to the electromagnet 61 of the operation unit 60. Then, the iron piece 62 of the electromagnet 61 is moved by the magnetic force in the direction shown in FIG. 4 downward so that the locking portion 63 is pulled out of the locking groove 65. Then, the repulsive force acts by the spring 64 to detach the plug 70 from the plug insertion hole, so that the plug can be automatically released when the short circuit occurs. In addition, when the plug is inserted after the short circuit is solved, the spring is returned again by pushing the plug release button, and the catching portion 63 is caught by the catching groove 65 again.
