The screw hole 21, through the screw hole 31 of the heater member 30 in order to fit through.

이후, 그 위에 누전배선차단기의 몸체(10)를 위치하여 몸체(10)에 형성된 체결공(12)을 통해 고정볼트(40)를 끼워 상기 고정볼트(40)가 핀돌기(111)의 상단부를 가압하면서 상기 히터부재(30)의 나사공(31), 바이메탈(20)의 나사공(21), 리드선(90) 연결단자(91)의 관통공(92)을 순차적으로 거쳐 너트고정돌기(114)에 거치된 너트(41)에 체결되도록 한다.Subsequently, the fixing bolt 40 is inserted through the fastening hole 12 formed in the body 10 by placing the body 10 of the ground fault circuit breaker thereon, and the fixing bolt 40 has an upper end portion of the pin protrusion 111. While pressing, the nut fixing protrusion 114 is sequentially passed through the screw hole 31 of the heater member 30, the screw hole 21 of the bimetal 20, and the through hole 92 of the connecting wire 91 of the lead wire 90. It is to be fastened to the nut 41 mounted on the).

즉, 상기 핀돌기(111)는 탄성수단(113)에 의해 탄지되어 있는바, 상기 고정볼트(40)가 핀돌기(111)의 상단을 가압하며 하강하면서 연결단자(90)와 바이메 탈(20) 및 히터부재(30)의 나사공(21)(31)에 끼워져 있던 부분이 고정볼트(40)로 대체되며 상기 고정볼트(40)가 너트(41)에 완전히 밀착되어 결과적으로 연결단자(90), 바이메탈(20), 히터부재(30)가 누전배선차단기의 몸체(10)에 완전히 고정되는 상태가 되는 것이다.That is, the pin protrusion 111 is supported by the elastic means 113, the fixing bolt 40 while pressing down the upper end of the pin protrusion 111, the connecting terminal 90 and the bimetal ( 20) and the part inserted into the screw holes 21 and 31 of the heater member 30 are replaced by the fixing bolt 40, and the fixing bolt 40 is completely adhered to the nut 41, and consequently, the connection terminal ( 90), the bimetal 20, the heater member 30 is to be completely fixed to the body 10 of the earth leakage circuit breaker.

그리고, 몸체(10)에 형성된 체결공(11)을 통해 볼트(45)를 삽입하여 트립어셈블리(70)를 고정하면 누전배선차단기가 완성된다.Then, when the bolt assembly 45 is inserted through the fastening hole 11 formed in the body 10 to fix the trip assembly 70, an earth leakage circuit breaker is completed.

이상에서 본 발명의 실시예에 따른 누전배선차단기 제조장치와 그 방법에 대해 설명하였으나 본 발명은 이에 한정하지 아니하며 당업자라면 그 응용과 변형이 가능함은 물론이다.Although the above-described leakage circuit breaker manufacturing apparatus and method thereof according to an embodiment of the present invention have been described, the present invention is not limited thereto, and those skilled in the art can of course apply and modify them.

예를 들어, 본 실시예는 적용대상을 PCB가 붙어있는 누전배선차단기로 도시하여 설명하고 있으나 PCB가 없는 통상의 과전류차단기의 경우 PCB(80)와 이에 포함되는 리드선(90)의 연결단자(91) 부분을 제외하고 그대로 적용하면 될 것이다.For example, in the present embodiment, the application target is illustrated as an earth leakage circuit breaker having a PCB. However, in the case of a general overcurrent circuit breaker without a PCB, the connection terminal 91 of the PCB 80 and the lead wire 90 included therein is shown. Except for the) part.
