Description

전원 플러그{POWER PLUG}Power plug {POWER PLUG}

본 발명은 전원 플러그에 관한 것으로, 더욱 상세하게는 전원코드에 과열이나 과부하가 발생되면 전원공급을 자동으로 차단하여 누전 및 화재를 방지할 수 있도록 이루어진 전원 플러그에 관한 것이다.The present invention relates to a power plug, and more particularly, to a power plug that is configured to automatically cut off the power supply when an overheat or overload occurs in the power cord to prevent a short circuit and a fire.

일반적으로 전원 플러그는 코드와 배선의 접속기구로서, 일반 가정에서 사용되는 가전제품이나 또는 산업현장에서 사용되는 산업용 기기(이하 "전기기구"라 칭함)에 전원을 공급하기 위한 접속기구로서 사용되고 있다.In general, the power plug is used as a connecting device for cords and wires, and is used as a connecting device for supplying power to home appliances used in ordinary homes or industrial devices (hereinafter, referred to as "electric appliances") used in industrial sites.

이러한 전원 플러그는, 전기기구와 연결된 코드의 선단부에 연결되며, 콘센트의 삽입구와 대응되는 구조를 갖추어 플러그를 콘센트에 삽입하면, 전원이 전기기구에 인가될 수 있도록 되어 있다.The power plug is connected to the distal end of the cord connected to the electric appliance, has a structure corresponding to the insertion hole of the outlet, and when the plug is inserted into the outlet, the power can be applied to the electric appliance.

그리고 상기 전기기구에는 전원 스위치가 설치되어 인가된 전원을 온/오프할 수 있도록 되어 있으며, 전기기구의 사용이 완료된 후에는 전원 스위치를 오프하여 전원 공급이 차단되도록 하고 있다.In addition, the electric appliance is provided with a power switch to turn on / off the applied power, and after the use of the electric appliance is completed, the power supply is turned off to cut off the power supply.

그러나 이러한 경우 전기기구는 예비전력이 소모되는 경우가 있는데, 이러한 예비전력의 소모를 방지하여 전기료를 절약할 수 있도록, 전원 스위치를 오프한 후에는 전원 플러그를 콘센트에서 뽑도록 권장하고 있다.However, in such a case, the electric appliance may consume extra power, and it is recommended that the power plug be unplugged from the outlet after the power switch is turned off to prevent the consumption of the spare power.

따라서, 전기기구를 사용하기 전에는 콘센트에 플러그를 삽입하고, 전기기구를 사용한 후에는 삽입된 플러그를 빼는 과정을 반복하는 경우가 많이 있다.Therefore, the plug is inserted into an outlet before using the electric appliance, and the process of removing the inserted plug is often repeated after using the electric appliance.

그러나 이렇게 콘센트에 전원 플러그를 삽입할 경우, 전원 플러그가 완전히 삽입되지 않은 상태에서 전기기구를 사용하면 접속부분에 과전류가 흘러 코드의 과열로 인하여 화재가 발생하는 문제점이 있다.However, when the power plug is inserted into the outlet, when the electric appliance is used in a state where the power plug is not completely inserted, there is a problem that a fire occurs due to overheating of the cord due to an overcurrent flow in the connection part.

그러한 것은 전력소모량이 많은 전기기구인 경우 코드가 과열될 가능성이 더욱 높다.This is more likely to cause the cord to overheat in electrical appliances with high power consumption.
