In particular, the present invention relates to a power cord winding device for an electric appliance developed to simplify the structure by improving the structure of the earth terminal and to have a good connection state.
일반적으로 전기기구용 전원코드 권취장치의 동작은 코드를 인출하기 위해서 코드를 한번 당기다가 놓으면 코드가 자동으로 고정되, 사용후 코드를 내장시키고자 할때는 인출되어진 코드를 약간 당겼다가 놓으면 회전판의 회동을 탄력적으로 제어하는 스톱퍼가 걸림턱으로부터 이탈되므로 태엽에 의해 회전판이 인출된 전원코드를 권취하는 것으로, 여기에서는 전기전자기구 사용시, 전원코드를 통해 전기기구에 전달되는 각종 노이즈 및 과부하를 흡수 소멸토록하며 전기기구를 보호할 목적으로 2개의 인입선과 1개의 접지선으로된 3선코드(이하 전원코드라 함)를 적용하기 위해서 어스단자가 부설된 전기기구용 전원코드 권취장치에 관한 것이다.In general, the operation of the power cord winding device for electric appliances pulls the cord once to release the cord, and then the cord is automatically fixed.When you want to embed the cord after use, pull the drawn cord a little and release the rotation of the rotating plate.

이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
전기기구용 전원코드 권취장치가 채용된 전기기구를 전원에 연결시키기 위해서 권취장치로 부터 전원코드(5)를 인출하고자 할 경우에는 전원코드(5)에 연결된 플러그 (9)를 잡고 당기면 전원코드(5)는 회전판(l)을 회전시켜주면서 인출구(10)를 해 인출되고 이와 동시에 회전판중심축(1)의 고정홈(1d)과 본체(2)의 고정홈(2b)에 양단이 고정된 태엽(4)은 감겨지게 되는 것이다.If you want to pull out the power cord (5) from the winding device in order to connect the electric appliance adopting the power cord winding device for the electric appliance to the power source, pull the plug (9) connected to the power cord (5) and pull the power cord ( 5) is a spring which is fixed at both ends in the fixing groove (1d) and the fixing groove (2b) of the main body (2) of the rotating plate central shaft (1) and withdrawal through the outlet 10 while rotating the rotating plate (l) (4) is to be wound.
이때 권취되어진 전원코드의 플러그와 전기콘센트거리에 따라 임의대로 소요길이만큼 인출하면서 놓으면 전원코드가 인출정지된다. 상기 동작은 스톱퍼(도면에 도시되지 않음)와 걸림턱(도면에 도시되지 않음)의 유기적인 관계에 의해서 이루어진다.At this time, depending on the plug and the electrical outlet distance of the wound power cord, the power cord is pulled out and stopped if it is withdrawn as required.

In this case, the lead wire 5a of the power cord 5 is connected to the connecting terminal 1c attached to the rotating plate 1, and the ground wire 5b is connected to the leaf spring 6, and fixed. The lead wire L and the ground wire A are connected to the lead wire connection terminal 7b and the ground connection terminal 7a of the terminal fixing member 7 installed in the center of the cover 3, respectively.
따라서 전기기구 사용시 기구에 전달되는 노이즈 및 과부하는 상기와 같이 구성된 권취장치의 어스단자(8)에서 흡수 소멸토록 된 것이다.Therefore, the noise and overload transmitted to the device when using the electric device is to be absorbed and extinguished in the earth terminal 8 of the winding device configured as described above.
이상에서 본 바와같이 본 고안은 전기기구용 전원코드 권취장치의 어스단자 구성시 종래것 처럼 전원코드의 접지선을 코일 스프링에 고정시킨 후 상기 코일스프링에 접속단자를 고정시켜야 하는 번거로움이 없어 어스단자의 설치 및 구조가 간단하고 또 어스단자의 구조가 간단하여 작업능률을 향상시킬 수 있으며, 또 탄력성과 유연성이 양호한 판스프링을 이용하면서 커버의 접속 단자를 변형함으로서 양호한 접지상태를 유지하도록함등 사용 및 제작상에 여러 장점이 있다.As seen from the above, the present invention has no need to fix the connection terminal to the coil spring after fixing the ground wire of the power cord to the coil spring as in the prior art when constructing the earth terminal of the power cord winding device for electric appliances. Simple installation and structure of the earth terminal and simple structure of the earth terminal can improve the work efficiency, and maintain good grounding state by modifying the connection terminal of the cover while using the leaf spring with good elasticity and flexibility. And there are several advantages in production.
