제1도는 본 고안의 구성요부를 나타낸 사시도.1 is a perspective view showing the main components of the present invention.

제2도는 본 고안의 정상 접점상태를 나타낸 측면도.Figure 2 is a side view showing a normal contact state of the present invention.

제3도는 본 고안에 과부하가 걸려 단락된 상태를 나타낸 측면도.3 is a side view showing a state in which the present invention is overloaded with a short circuit.

본 고안은 정격전압을 필요로 하는 모우터 등에 부착 사용하는 과부하차단기를 110V와 220V 겸용으로 사용할 수 있게 한 과부하 차단기에 관한 것이다.The present invention relates to an overload circuit breaker that can be used as a 110V and 220V for the overload circuit breaker attached to the motor requiring a rated voltage.

종래에도 과부하가 걸림을 방지하기 위한 차단기가 제안 사용되었으나 이는 정격전압에 따라 110V와 220V용을 각기 구입하여 부착 사용해야 했기 때문에 정격 전압에 맞추어 구입해야 하는 경제적 문제점이 많았던 것으로 현재와 같이 110V와 220V를 겸용으로 사용하고 있는 시점에서는 하나의 차단기를 가지고도 임의로 조작 사용할 수 있는 과부하 차단기의 출현을 갈망하고 있는 실정인 것이다.Conventional circuit breakers have been proposed and used to prevent overloading. However, since 110V and 220V were purchased separately and used according to the rated voltage, there were many economic problems to purchase according to the rated voltage. At the time of dual use, the situation is eager for the emergence of an overload circuit breaker that can be arbitrarily operated even with one circuit breaker.

본 고안은 상기한 바와 같은 문제점을 시정코져 제안된 것으로 모우터로 흐르는 전류계 설정전압이상인 과전류가 흘러 과부하가 걸리게 되며 열선이 가열되므로서 바이메탈을 작동시켜 자동으로 전원을 단락시켜 주어 모우터에 과부하가 걸리지 않게 하므로서 모우터 소손 등 사용불능의 문제점을 미연에 방지할 수 있는 것으로 110V와 220V 등 어느 것이든 하나의 차단기로 조작 사용할 수 있게 함에 목적이 있다.The present invention is proposed to correct the problems described above, the over-current flows over the ammeter set voltage flowing to the motor is overloaded and the heating wire is heated to automatically short-circuit the power supply to operate the bimetal, so that the motor is overloaded It is possible to prevent unused problems such as motor burnout by preventing it from being caught, and has the purpose of enabling one to operate one breaker such as 110V and 220V.

본 고안의 내용을 첨부도면에 의해 상세히 설명하면 다음과 같다.If the content of the present invention will be described in detail by the accompanying drawings as follows.

즉, 과부하 차단기(1)를 구성하는 바이메탈(2)의 상단부에 110V용 열선(3)을 배선하고 외측에 220V용 접점편(4)을 직립시키며 바이메탈 하측에 위치케 한 220V용 열선(5)의 일단(5a)을 동 접점편(4)에 나착연결하며 타단(5)은 탄발스위치 접점판(6)과 접점케 된 공동접점편(7)에 나착 고정시켜 되는 110V/22V 겸용 과부하 차단기인 것이다.That is, the 220V heating wire 5 in which the 110V heating wire 3 is wired to the upper end of the bimetal 2 constituting the overload circuit breaker 1, the 220V contact piece 4 is erected on the outside, and the bimetal 2 is placed below the bimetal. End (5a) is a 110V / 22V combined overload circuit breaker that is fixedly attached to the copper contact piece (4) and the other end (5) is fixed to the joint contact piece (7) contacted with the bullet switch contact plate (6) will be.

미설명부호 8은 110V용 접점편, 9는 접점버튼, 10은 바이메탈에 부착된 가압돌기, a.b.c는 인입전선을 표시한다.Reference numeral 8 denotes a contact piece for 110V, 9 denotes a contact button, 10 denotes a pressing protrusion attached to a bimetal, and a.b.c denotes an incoming wire.

본 고안의 작동효과를 설명하면 다음과 같다.Referring to the operation effect of the present invention is as follows.

예시도면 제2도에서 보는 바와 같이 접점버튼(9)을 가압시켜 탄발스위치 접점판(6)이 공동접점편(7)에 밀접되게 하여 전류가 흐르게 하며 110V용 모우터에 사용할 경우에는 110V용 접점편(8)에 배선된 전선(a)와 탄발스위치 접점판(6)에 배선된 전선(b)을 연결 사용하면 110V용 열선(3)으로 전류가 흐르게 되므로 과전류로 인해 과부하가 걸리게 되면 열선(3)에 고열이 생기면서 바이메탈(2)을 작동시켜 하향되므로서 예시도면 제3도에서와 같이 가압돌기(10)가 스위치 접점판(6)을 가압하므로서 공동 접점편(7)으로부터 떨어져 전원이 단락되어지는 것이다. 따라서 모우터에 과전류로 인한 과부하를 미연에 차단시켜 주어 모우터의 소손등 위험을 배제할 수 있는 것이다.As shown in FIG. 2, the contact button 9 is pressed to bring the bullet switch contact plate 6 close to the common contact piece 7 so that current flows, and when used in a 110V motor, the 110V contact. When the wire (a) wired on the piece (8) and the wire (b) wired on the bullet switch contact plate 6 are used, current flows through the 110V heating wire 3, so if an overload occurs due to overcurrent, the heating wire ( As the high temperature is generated in 3), the bimetal 2 is moved downward, and as shown in FIG. 3, the pressing protrusion 10 presses the switch contact plate 6 so that the power source is separated from the common contact piece 7. It is shorted. Therefore, by overloading the overload due to the overcurrent in the motor can be eliminated the risk of damage to the motor.

220V용 모우터에 사용할 경우에는 220V용 접점편(4)에 배선된 전선(c)과 탄발스위치 접점판(6)에 배선된 전선(b)을 연결 사용하면 상술한 바와 같이 220V용 열선(5)으로 전류가 흘러 정상작동되든 것이 과전류가 흐르면 열선(5)에 고열이 생기면서 바이메탈(2)에도 열이 가해져 작동되므로서 스위치 접점판(6)을 공동접점편(7)으로부터 떨어져 전원이 단락되어지게 되는 것이다.In case of using for 220V motor, if wire (c) wired to 220V contact piece (4) and wire (b) wired to carbon switch contact plate 6 are used, the 220V heating wire (5) When the current flows through the current to normal operation, if the overcurrent flows, the heating wire 5 is heated and the bimetal 2 is heated to operate the switch contact plate 6 away from the common contact piece 7 to short-circuit the power supply. It will be done.

이와 같이 작동되는 본 고안의 과부하 차단기를 사용하면 정격모우터에 과전류로 인한 과부하현상을 배제하므로서 모우터의 소손을 방지할 수 있고, 하나의 차단기를 가지고도 110V나 220V등 임의로 연결 실시할 수 있는 경제적이고 실용적인 고안인 것이다.By using the overload circuit breaker of the present invention operated as described above, the motor can be prevented from being burned by eliminating the overload phenomenon caused by the overcurrent in the rated motor, and can be arbitrarily connected such as 110V or 220V even with one circuit breaker. It is an economical and practical design.
