본 발명은 자동취출식 플러그에 관한 것으로서, 보다 상세하게는 플러그 하우징에 이젝터봉이 탄성스프링과 함께 설치되어 버튼을 누르면 탄성스프링의 탄성 력에 의해 이젝터봉이 돌출되어 콘센트의 접속부를 밀어주므로 어린이나 노약자도 쉽게 플러그를 취출할 수 있고, 특히 플러그가 순식간에 콘센트상에서 분리되므로 플러그 취출과정에서 발생되는 감전사고가 미연에 예방되는 자동취출식 플러그에 관한 것이다.The present invention relates to a self-extracting plug, and more particularly, the ejector rod is installed in the plug housing together with the elastic spring, and when the button is pressed, the ejector rod is protruded by the elastic force of the elastic spring, thereby pushing the connection part of the outlet. The plug can be easily taken out, and in particular, since the plug is disconnected from the outlet in an instant, the present invention relates to an automatic plug type plug which prevents an electric shock occurring in the plug taking out process.

통상적으로 플러그는 옥내배선에 연결된 콘센트에 접속되어 필요로 하는 전자·전기제품에 전기를 공급하고, 사용 후 콘센트에서 분리되어 전기공급을 차단함은 물론 전자·전기제품과 함께 보관된다. 이처럼 전자·전기제품을 사용함에 있어 수시로 플러그를 콘센트에 접속 및 분리해야 하므로 사용자가 보다 쉽고 간편하게 플러그를 취출하도록 구비되어야 한다.In general, the plug is connected to the outlet connected to the indoor wiring to supply electricity to the required electronic and electrical appliances, and after use, it is separated from the outlet to cut off the electricity supply and is also stored with the electronic and electrical appliances. As such, in using electronic and electrical products, the plug must be connected to and disconnected from the outlet at any time, so that the user can be easily and conveniently taken out of the plug.

이에 따라 대한민국 특허고개번호 특1998-019438호(명칭: 전자석을 이용한 플러그 인출장치)에서 소켓으로부터 먼 곳에 위치한 상태에서도 소켓으로부터 플러그를 쉽게 뺄 수 있고, 플러그를 소켓으로부터 안전하게 인출할 수 있도록 하는 전자석을 이용한 플러그 인출장치를 선출원한바 있다. 이는 사용자가 소켓이 있는 위치까지 가지 않고도 전자석에 전류를 공급하는 전자석 단속스위치를 누르기만 하면 플러그 단자들이 소켓으로부터 인출되도록 이루어진 구성이다.Accordingly, in Korea Patent Publication No. 1998-019438 (name: plug take-out device using electromagnet), it is possible to easily remove the plug from the socket even if it is located far from the socket, and to securely pull the plug out of the socket. The previously used plug-out device has been filed. This allows the plug terminals to be drawn out of the socket simply by pressing the electromagnetism interrupt switch that supplies current to the electromagnet without going to the position where the socket is located.

하지만, 상기 전술하는 전자석을 이용한 플러그 인출장치는 전자석에 전기를 공급하기 위한 전자석 전원공급선과 전자석 단속스위치가 별도로 구비되어야 하고, 이때 전원공급선은 플러그 접속 단자들과 연결되는 전원공급선과 함께 연결케이블에 피복되어야하므로 구조가 상당히 조잡하다.However, the above-described plug extracting apparatus using an electromagnet should be provided with an electromagnet power supply line and an electromagnet intermittent switch for supplying electricity to the electromagnet, wherein the power supply line is connected to the connection cable together with the power supply line connected to the plug connection terminals. The structure is quite coarse because it must be clad.

또한, 플러그 접속 단자가 플러그 본체 내부에서 전·후방향으로 슬라이드 이송되도록 설치되므로 반복적인 유동으로 인해 전원공급선이 단락될 우려가 크고, 이는 플러그 본체 내부에 복합적으로 설치되는 플러그 접속 단자의 전원공급선 혹은 전자석 전원공급선에 접속되어 전기합선으로 인한 안전사고를 초래한다.In addition, since the plug connection terminal is installed to slide forward and backward in the plug main body, there is a high possibility that the power supply line is shorted due to repetitive flow, which is a power supply line of the plug connection terminal which is installed in the plug main body or It is connected to the electromagnet power supply line and causes safety accident due to short circuit.

한편, 상기 전술한 발명에 국한되지 아니하고 당업계에서는 영구자석 및 전자석을 이용한 플러그 인출장치를 꾸준히 연구개발하고 있지만, 플러그 취출과 같은 간단한 작업을 별도의 스위치를 통하여 자동으로 행함에 있어 번거로운 단점이 따르고, 플러그의 제조단가조차 고가이다 보니 사용자들이 외면하는 실정이다.On the other hand, the present invention is not limited to the above-described invention, but the art has been steadily researching and developing a plug-out device using a permanent magnet and an electromagnet, but it has a cumbersome disadvantage in automatically performing a simple operation such as taking out a plug through a separate switch. As a result, even the manufacturing cost of the plug is expensive, so users are ignored.

이에 따라 본 발명은 상기한 점에 착안하여 안출한 것으로서, 보다 상세하게는 플러그 하우징에 이젝터봉이 탄성스프링과 함께 설치되어 버튼을 누르면 탄성스프링의 탄성력에 의해 이젝터봉이 돌출되어 콘센트의 접속부를 밀어주므로 어린이나 노약자도 쉽게 플러그를 취출할 수 있고, 특히 플러그가 순식간에 콘센트상에서 분리되므로 플러그 취출과정에서 발생되는 감전사고가 미연에 예방되는 자동취출식 플러그를 제공하는 것을 그 목적으로 한다.Accordingly, the present invention has been made in view of the above point, more specifically, the ejector rod is installed in the plug housing together with the elastic spring, and when the button is pressed, the ejector rod is protruded by the elastic force of the elastic spring to push the connection part of the outlet. The elderly and the elderly can easily take out the plug, and in particular, since the plug is disconnected from the outlet in an instant, an object of the present invention is to provide an automatic plug that prevents an electric shock occurring in the plug taking out process.

이러한 목적을 달성하기 위해 본 발명은 플러그(P)의 접속단자(P1)와 함께 중앙부에 로드공(12a)(14a)이 형성되는 제1, 2안내부재(12)(14)가 내부에 설치되는 플러그 하우징(10); 상기 플러그 하우징(10)의 제1안내부재(12)에 수용되고, 단턱부(22)를 중심으로 일단에 탄성스프링(24b)이 개재되면서 끝단에 후크(24a)가 형성되는 로드부(24)와, 다른 일단으로 연장되어 플러그 하우징(10) 외부로 돌출되는 밀편부(26)가 구비되는 이젝터봉(20); 및 상기 플러그 하우징(10)의 제2안내부재(14)에 복귀스프링(30a)과 함께 수용되고, 일단에 플러그 하우징(10) 측면으로 돌출되는 버튼(32)과 중앙부에 이젝터봉(20)의 후크(24a)가 결속되도록 후크홈(34)이 형성되는 스톱부재(30);를 포함하여 구성되는 것을 특징으로 한다.In order to achieve the above object, the present invention is provided with first and second guide members 12 and 14 having rod holes 12a and 14a formed at the center thereof together with connection terminals P1 of the plug P.

그리고, 상기 제2안내부재(14)는 제1안내부재(12)의 선단부에 인접하도록 설 치되고, 후술하는 스톱부재(30)가 횡방향으로 슬라이드이송되도록 중앙부에 로드공(14a)과 스톱부재(30)의 버튼(32)이 플러그 하우징(10) 외측으로 노출되도록 일측에 통공(14b)이 형성된다.In addition, the second guide member 14 is installed to be adjacent to the front end of the first guide member 12, the rod member 14a and the stop in the center portion so that the stop member 30, which will be described later, slides in the transverse direction. A through hole 14b is formed at one side such that the button 32 of the member 30 is exposed to the outside of the plug housing 10.

또한, 본 발명에 따른 이젝터봉(20)은 플러그 하우징(10)의 제1안내부재(12)에 수용되고, 단턱부(22)를 중심으로 일단에 탄성스프링(24b)이 개재되면서 끝단에 후크(24a)가 형성되는 로드부(24)와, 다른 일단으로 연장되어 플러그 하우징(10) 외부로 돌출되는 밀편부(26)가 구비된다. 이젝터봉(20)은 플러그 하우징(10)의 제1안내부재(12)를 타고 슬라이드 이송되는 단턱부(22) 양단에 로드부(24)와 밀편부(26)가 일체로 형성된다.In addition, the ejector rod 20 according to the present invention is accommodated in the first guide member 12 of the plug housing 10, and hooks at the ends while the elastic spring 24b is interposed at one end about the stepped portion 22. The rod part 24 in which the 24a is formed is provided, and the push piece part 26 which extends to the other end and protrudes out of the plug housing 10 is provided. The ejector rod 20 is integrally formed with the rod part 24 and the pinnacle part 26 at both ends of the stepped portion 22 which is slide-transported through the first guide member 12 of the plug housing 10.

여기서, 상기 로드부(24)는 끝단에 후술하는 스톱부재(30)와 결속되는 후크(24a)가 형성됨과 함께 탄성스프링(24b)이 개재된 상태로 제1, 2안내부재(12)(14)상에 수용되고, 밀편부(26)는 플러그 하우징(10)의 외부로 돌출가능하게 형성된다. 이때 단턱부(22)는 제1안내부재(12) 일단에 면접된 상태로 정지되어 밀편부(26)의 돌출길이를 제안한다.Here, the rod portion 24 has a hook (24a) that is coupled to the stop member 30 to be described later at the end and the first, second guide member (12) (14) with the elastic spring (24b) is interposed ) Is received, and the pressing piece 26 is formed to protrude out of the plug housing 10. At this time, the stepped portion 22 is stopped in a state of being interviewed at one end of the first guide member 12 and proposes the protruding length of the whole piece portion 26.

이처럼, 상기 이젝터봉(20)은 제1, 2안내부재(12)(14)의 로드공(12a)(14a)에 수용된 상태로 탄성스프링(24b)의 탄성력에 의해 밀편부(26)가 플러그 하우징(10) 외부로 돌출되려는 이송력이 작용하고, 외력에 의해 이젝터봉(20)이 후방으로 이송시 탄성스프링(24b)의 탄성력이 압축된 상태로 후크(24a)가 스톱부재(30)에 결속되어 위치고정되는바, 이에 따른 스톱부재(30)의 상세한 설명은 후술하는 내용을 참조한다.As such, the ejector rod 20 is plugged by the elastic force of the elastic spring 24b in a state where the ejector rod 20 is accommodated in the rod holes 12a and 14a of the first and second guide members 12 and 14. The feed force to protrude out of the housing 10 acts, and when the ejector rod 20 is conveyed backward by the external force, the hook 24a is compressed to the stop member 30 in a state in which the elastic force of the elastic spring 24b is compressed. Bound and fixed position, the detailed description of the stop member 30 according to this reference will be described later.

또한, 본 고안에 따른 스톱부재(30)는 제2안내부재(14)의 로드공(14a)에 복귀스프링(30a)과 함께 수용되고, 일단에 플러그 하우징(10) 측면으로 돌출되는 버튼(32)과 중앙부에 이젝터봉(20)의 후크(24a)가 결속되도록 후크홈(34)이 형성된다. 스톱부재(30)는 제2안내부재(14)의 로드공(14a)에 복귀스프링(30a)과 함께 수용되어 횡방향으로 슬라이드이송되되, 이때 스톱부재(30)는 복귀스프링(30a)의 탄성력에 의해 일측으로 밀착되면서 버튼(32)이 플러그 하우징(10)의 측면에 형성된 통공(14b)을 통하여 외부로 돌출된다.In addition, the stop member 30 according to the present invention is accommodated together with the return spring 30a in the rod hole 14a of the second guide member 14, the button 32 protruding toward the plug housing 10 side at one end ) And a hook groove 34 is formed to bind the hook 24a of the ejector rod 20 to the center. The stop member 30 is accommodated together with the return spring 30a in the rod hole 14a of the second guide member 14 and slides in the transverse direction, wherein the stop member 30 is the elastic force of the return spring 30a. While being in close contact with one side by the button 32 is protruded to the outside through the through hole (14b) formed on the side of the plug housing (10).

그리고, 상기 스톱부재(30)는 중앙부에 이젝터봉(20)의 후크(24a)를 수용하면서 결속되도록 후크홈(34)이 형성된다. 후크홈(34)은 후크(24a)의 단면형상보다 크게 형성되고, 복귀스프링(30a)에 의해 일측으로 밀착되는 스톱부재(30)와 함께 이젝터봉(20)의 중심과 어긋난 상태로 대기한다. 이에 외력에 의해 이젝터봉(20)의 후크(24a)가 후크홈(34)에 진입시 스톱부재(30)가 일시적으로 횡방향으로 이송되었다가 후크(24a)의 집입이 완료되는 즉시 복귀스프링(30a)에 의해 복귀되어 후크홈(34)상에 후크(24a)가 서로 맞물린다. 그리고 사용자가 버튼(32)을 누르면 스톱부재(30)가 횡방향으로 이송되어 후크홈(34)에 결속된 후크(24a)가 이탈되므로 이젝터봉(20)이 탄성스프링(24b)의 탄성력에 의해 돌출된다.In addition, the stop member 30 has a hook groove 34 formed so as to bind while receiving the hook 24a of the ejector rod 20 at the center portion. The hook groove 34 is formed to be larger than the cross-sectional shape of the hook 24a, and stands with the stop member 30 in close contact with one side by the return spring 30a in an offset state from the center of the ejector rod 20. Accordingly, when the hook 24a of the ejector rod 20 enters the hook groove 34 by an external force, the stop member 30 is temporarily transferred in the transverse direction, and immediately after the insertion of the hook 24a is completed, the return spring 30a is completed. The hooks 24a are engaged with each other on the hook groove 34 by returning by the " And when the user presses the button 32, the stop member 30 is transferred in the transverse direction so that the hook 24a bound to the hook groove 34 is released, so that the ejector rod 20 is driven by the elastic force of the elastic spring 24b. It protrudes.

한편, 도 1 내지 3에서 이젝터봉(20)이 플러그하우징(10)의 중앙부에 독립적으로 설치된 구성을 도시하고 있지만, 이에 국한되지 않고 플러그의 취출이 보다 용이하도록 서로 대향하는 위치에 하나 이상으로 더 구비되는 구성도 가능하다.On the other hand, although the ejector rod 20 in Figures 1 to 3 is shown to be configured independently of the central portion of the plug housing 10, but is not limited to this one or more in a position facing each other to facilitate the extraction of the plug more easily. The provided structure is also possible.

작동상에 있어서, 우선 사용자가 전자·전기제품을 사용하기 위해 플러그(P) 의 전원단자(P1)를 콘센트(C)에 꽂으면, 도 3a처럼 이젝터봉(20)의 밀편부(26)가 콘센트(C)의 접속부에 면접되어 후방으로 이송되면서 탄성스프링(24b)이 압축된 상태로 후크(24a)가 스톱부재(30)의 후크홈(34)에 맞물려 결속된다. In operation, first, when the user inserts the power supply terminal P1 of the plug P into the outlet C in order to use electronic and electrical appliances, the dense portion 26 of the ejector rod 20 is opened as shown in FIG. 3A. The hook 24a is engaged with and engaged with the hook groove 34 of the stop member 30 in a state in which the elastic spring 24b is compressed while being interviewed by the connection portion of the outlet C and moved backward.

그리고 전자·전기제품의 사용을 완료한 후, 플러그(P)를 취출시 사용자가 플러그 하우징(10) 외부로 돌출된 버튼(32)을 누르면 도 3d와 같이 스톱부재(30)가 횡방향으로 이송되면서 후크홈(34)에 맞물린 후크(24a)가 이탈되고, 이어서 이젝터봉(20)이 탄성스프링(24b)의 탄성력에 의해 순간적으로 돌출되어 밀편부(26)가 콘센트(C)의 접속부를 밀어주므로 플러그(P)가 쉽고 간편하게 취출되는 이점이 있다.After the use of the electronic and electrical products, when the user pulls out the plug P, when the user presses the button 32 protruding out of the plug housing 10, the stop member 30 is transferred in the horizontal direction as shown in FIG. 3D. While the hook 24a engaged with the hook groove 34 is released, the ejector rod 20 is momentarily protruded by the elastic force of the elastic spring 24b so that the push piece 26 pushes the connection part of the outlet C. Since the plug (P) is easy and simple to take out the advantage.

이상의 구성 및 작용에 의하면, 본 발명은 플러그 하우징에 이젝터봉이 탄성스프링과 함께 설치되어 버튼을 누르면 탄성스프링의 탄성력에 의해 이젝터봉이 돌출되어 콘센트의 접속부를 밀어주므로 어린이나 노약자도 쉽게 플러그를 취출할 수 있고, 특히 플러그가 순식간에 콘센트상에서 분리되므로 플러그 취출과정에서 발생되는 감전사고가 미연에 예방되는, 유용한 효과가 있다.According to the above configuration and action, the present invention is installed in the plug housing together with the elastic spring, when the button is pressed, the ejector rod is protruded by the elastic force of the elastic spring to push the connection of the outlet, so children or the elderly can easily take out the plug. In particular, since the plug is immediately disconnected from the outlet, an electric shock occurring in the plug ejection process is prevented in advance.
