본 고안은 110V용과 220V용으로 전환하여 사용할 수 있으며 전기 전자기기에 110V/220V 전환스위치를 설치할 필요가 없도록 한 110V/220V 겸용플러그에 관한 것이다.The present invention relates to a 110V / 220V dual plug that can be used to switch between 110V and 220V, and do not need to install a 110V / 220V switch in electrical and electronic equipment.

일반적인 플러그는 220V용으로 고정된 것으로 110V용으로 사용시에는 반드시 어댑터를 끼워야 했기 때문에 어댑터 만큼 길이가 길어지고 무게가 증가되어 콘센트에 꽂았을때 벽면으로 부터 길게 돌출되어 나오며 밑으로 처져서 접촉이 불량하게 되고 어댑터가 쉽게 빠져서 분실의 염려가 있는 등 폐단이 있었다.The general plug is fixed for 220V, and when it is used for 110V, the adapter must be inserted, so it is as long as the adapter and the weight is increased. When it is plugged into the outlet, it protrudes from the wall and falls down. The adapter was easily pulled out and there was a risk of loss.

또한 어댑터를 끼우고 빼는 것에 의해 플러그자체의 110V/220V 전환은 이루어지나 전기 전자기기에 설치된 110V/220V 전환스위치를 전환하지 않으면 사용할수 없게 되므로 그 전환조작이 번거롭게 되며, 전기 전자기기에 110V/220V 전환스위치를 설치함에 따른 원가 상승을 초래하게 되는 폐단이 있었다.In addition, the plug itself can be switched between 110V / 220V by plugging in and unplugging the adapter. However, if the 110V / 220V switching switch installed in the electronic device is not switched, the operation becomes cumbersome. There was a closure that caused the cost increase by installing the changeover switch.

따라서 본 고안은 이러한 종래의 제반 폐단을 해소하기 위하여 간단한 조작으로 110V용 평형단자와 220V용 환형단자가 선택적으로 돌출되게 조립할수 있도록 함으로써 별도의 어댑터를 사용하지 않고도 110V용과 220V용으로 전환하여 사용할 수 있으며, 이에 따라 플러그 전체의 길이가 짧고 경량화되어 콘센트에 꽂았을 때 길게 돌출되지 않으며 밑으로 쳐지지 않아 접속 불량을 방지 할수 있도록 한 110V/220V 겸용 플러그를 제공하려는 것이다.Therefore, the present invention allows the 110V balanced terminal and the 220V annular terminal to be selectively protruded by simple operation in order to solve the conventional closed ends, so that the switch can be used for 110V and 220V without using an additional adapter. Therefore, the whole length of the plug is short and lightweight, so that it does not protrude long when plugged into the outlet, and does not fall down to provide a 110V / 220V dual plug that prevents a poor connection.

또한 본 고안은 전기 전자기기에 접속되게 함으로써 전기 전자기기에 별도의 110V/220V 전환스위치를 설치하지 않고도 플러그만을 전환시키는 것만으로 간편하게 전환 할 수 있도록 하려는 것이다.In addition, the present invention is to be connected to the electrical electronics to be able to switch simply by switching only the plug without installing a separate 110V / 220V conversion switch in the electrical and electronics.

이하 본 고안을 첨부도면에 도시한 실시예에 따라서 상세히 설명한다.Hereinafter, the present invention will be described in detail according to the embodiment shown in the accompanying drawings.
