Description

전원 플러그{power source plug}Power plug

본 발명은 전원 플러그에 관한 것으로서, 더욱 상세하게는 콘센트로부터 원터치로 쉽게 분리할 수 있는 전원 플러그에 관한 것이다.The present invention relates to a power plug, and more particularly, to a power plug that can be easily removed from the outlet by one touch.

통상적으로, 플러그는 가정의 전기기기에 부착되어 콘센트 단자와 플러그 단자가 서로 접속 및 분리되어 전원을 공급 및 단속한다.Typically, plugs are attached to household electrical equipment so that the outlet terminals and plug terminals are connected and disconnected from each other to supply and interrupt power.

이러한 기존의 플러그의 경우에는 사용자가 플러그 몸체를 손으로 파지한 후 콘센트 단자에 삽입하거나 분리시키는 것으로, 분리시에 손에 물기가 묻어 안전사고에 노출되거나 어린이나 노약자들이 콘센트에서 플러그를 분리시키는 작업이 용이하지 않았다.In the case of such a conventional plug, the user grasps the plug body by hand, and then inserts or removes the plug into the outlet terminal. This was not easy.

이와 관련하여, 국내 실용신안등록 제255369호의 "전원 플러그"는 콘센트에 전원이 인가된 상태에서 버튼을 누르면 진출된 입력단자의 전방에 부착된 스프링의 탄발력으로 인하여 푸셔와 함께 입력단자가 플러그몸체의 후방으로 슬라이드 이동하게 되어 전원이 차단되는 것으로서, 이 경우에는 전적으로 스프링의 탄발력에 의지하여 콘센트에 삽입된 플러그의 입력단자를 후퇴시키는 충분한 힘을 얻을 수 없다는 문제점이 있다.In this regard, the "power plug" of Korean Utility Model Registration No. 255369, when the button is pressed while the power is applied to the outlet, the input terminal together with the pusher due to the elasticity of the spring attached to the front of the entered input terminal The slide is moved to the rear to cut off the power. In this case, there is a problem that it is not possible to obtain a sufficient force to retreat the input terminal of the plug inserted into the outlet solely on the spring force.

본 발명은 상기와 같은 제반 문제점을 해결하기 위하여 창안된 것으로서, 플러그의 입력단자를 후퇴시키는 충분한 힘을 얻기 위해 스프링의 탄발력과 함께 누름돌기가 구비되어 입력단자를 후퇴시키는 전원 플러그를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, to provide a power plug for retracting the input terminal is provided with a push projection with a spring force to obtain a sufficient force for retracting the input terminal of the plug. There is this.

한쌍의 입력단자(31)가 외부에 돌출되도록 구비된 전원 플러그(1)에 있어서,In the power plug 1 provided so that a pair of input terminals 31 protrude to the outside,

상기 입력단자(31)가 출몰하는 출몰공(11)이 상측에 구비되고, 하단에 힌지핀(40)이 삽입되는 핀공(12)과 좌우 양측에 버튼부(20)의 누름에 따른 상기 핀(40)축에 대한 회동 동작을 가이드하는 가이드홈(13)으로 구성된 케이스(10)와;The pin (12) is provided on the upper side, the pin hole 12, the hinge pin 40 is inserted into the lower end and the pin (12) according to the pressing of the button portion 20 on both sides of the input terminal (31) 40) a case 10 composed of a guide groove 13 for guiding a rotational motion about the shaft;

상단과 중앙에 각각 제1스프링(50)에 의해 탄력지지되는 버튼(24)과 누름돌기(21a)(21b)가 형성되며, 하단에 걸림쇠(22)와 상기 흰지핀(40)이 관통 삽입되는 핀공(23)을 구비하며, 상기 좌우 양측의 가이드홈(13)에 삽입되는 버튼부(20)와;The button 24 and the pressing protrusions 21a and 21b which are elastically supported by the first spring 50 at the upper end and the center are respectively formed, and the latch 22 and the white paper pin 40 are inserted through the lower end. A button part 20 having a pin hole 23 and inserted into the guide grooves 13 on both the left and right sides thereof;

상방의 제2스프링(60)에 의해 후방으로 탈력 설치되며, 상기 출몰공(11)에 출몰되는 입력단자(31)와 중앙에는 상기 걸림쇠(22)를 수용하는 수용공(32)이 하단에는 상기 입력단자(31)를 전방으로 밀어주는 푸셔(33)로 구성된 몸체(30); 를 포함한다.The rear end is installed by the upper second spring 60 upward, and the input terminal 31 and the center receiving hole 32 to receive the latch 22 in the central hole 11 is located at the bottom A body 30 composed of a pusher 33 for pushing the input terminal 31 forward; It includes.

바람직하게, 상기 버튼부(20)가 누름에 따라 상기 핀(40) 축에 대한 회동 동작시, 상기 케이스(10) 내에서 상기 양측의 누름돌기(21a)(21b)는 서로 교차되게 되는 것을 특징으로 한다.Preferably, as the button unit 20 is pressed, the push protrusions 21a and 21b on both sides of the case 10 intersect with each other in the rotation operation about the pin 40 axis. It is done.

이하, 첨부된 도면을 참조로 본 고안의 바람직한 실시예를 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 전원 플러그를 보여주는 분해 사시도이며, 도 2는 본 고안에 따른 전원 플러그를 보여주는 저면 사시도이며, 나아가 도 3a와 도 3b는 본 고안에 따른 전원 플러그의 작동상태를 보여주는 횡단면도이다.1 is an exploded perspective view showing a power plug according to the present invention, FIG. 2 is a bottom perspective view showing a power plug according to the present invention, and FIGS. 3A and 3B are cross-sectional views showing an operating state of the power plug according to the present invention. .

도면을 참조하면, 본 발명에 따른 전원 플러그(1)는 케이스(10) 양측에 구비된 가이드홈(13)에 삽입되는 양측의 버튼부(20)의 돌출된 버튼(24)을 동시에 누르면, 하단의 핀공(23)에 관통 삽입된 흰지핀(40)의 축을 중심으로 회동되며, 누르는 힘을 제거하게 되면, 제1스프링(50)의 탄발력에 의해 버튼(24)은 원위치되게 된다.Referring to the drawings, the power plug 1 according to the present invention by pressing the protruding button 24 of the button portion 20 on both sides to be inserted into the guide groove 13 provided on both sides of the case 10, Rotating around the axis of the white paper pin 40 inserted through the pin hole 23 of the, and when the pressing force is removed, the button 24 is returned to its original position by the elastic force of the first spring (50).

이때, 걸림쇠(22)와 푸셔(33)의 일측이 하방에서 서로 맞물려 있다가 상기와 같이 버튼(24)을 누르는 일련의 작동 과정으로 인하여 맞물려 있던 걸림쇠(22)는 흰지핀(40)의 축을 중심으로 상기한 버튼(24)의 누름 방향과 동일 회전방향으로 점차 벌어지고, 중앙에 갈고리 형상의 누름돌기(21a)(21b) 또한 흰지핀(40)을 중심축으로 동일 방향으로 회전되어 수용공(32)의 일측을 하방으로 밀어줌과 동시에, 하방으로 제1스프링(50)의 탄발력 또한 동시에 작용되어, 입력단자(31)는 콘센트 단자로부터 이탈되며, 입력단자(31)의 끝부분만 출몰공(11)에 돌출된 상태가 되게 된다.At this time, one side of the latch 22 and the pusher 33 is engaged with each other from below, and the latch 22 that is engaged due to a series of operating processes of pressing the button 24 as described above is centered on the axis of the white paper pin 40. Gradually open in the same rotational direction as the pressing direction of the button 24, and the pressing protrusions 21a and 21b of the hook shape in the center are also rotated in the same direction about the white paper pin 40 in the center of the receiving hole ( At the same time pushing the one side of the 32) downward, the elastic force of the first spring 50 also acts downwards, the input terminal 31 is separated from the outlet terminal, only the end of the input terminal 31 in the appearance The protruding state to the ball 11 will be.

도 3b의 누름돌기(21a)(21b) 부분을 인출하여 평면으로 나타낸 도면에서 보여지는 바와 같이, 양측의 누름돌기(21a)(21b)는 회동시 서로 교차되므로 간섭이 없다.As shown in the drawing in which the pusher protrusions 21a and 21b of FIG. 3B are drawn out in a plan view, both pusher protrusions 21a and 21b cross each other at the time of rotation, so there is no interference.

상기 입력단자(31)를 콘센트 단자에 연결시킬 때에는 콘센트 하측에 구비된푸셔(33)를 밀어주면, 도 3a에서와 같이 입력단자(31)가 출몰공(11)에 돌출된 상테가 되게 된다.When the input terminal 31 is connected to the outlet terminal, when the pusher 33 provided on the lower side of the outlet is pushed, the input terminal 31 becomes a top surface protruding from the hole 11 as shown in FIG. 3A.

상기와 같이 콘센트에서 플러그를 이탈시키는 충분한 힘을 얻기 위해서는 양측의 버튼(24)을 동시에 파지한 후 눌러주어야 일련의 동작이 이루어진다. 따라서, 사용자의 의도와 관계없는 실수나 우연한 접촉에 의한 오작동율은 현저하게 감소되게 된다.In order to obtain a sufficient force to remove the plug from the outlet as described above, the button 24 on both sides at the same time gripping and pressing a series of operations are made. Therefore, the malfunction rate due to mistake or accidental contact irrespective of the user's intention is significantly reduced.

덧붙여, 본문에서 미설명된 도면부호, 70은 코드이다.In addition, reference numeral 70, which is not described in the text, is a code.

이상과 같이, 본 발명은 비록 한정된 실시예와 도면에 의해 설명되었으나, 본 고안은 이것에 의해 한정되지 않으며, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해, 본 발명의 기술사상과 아래에 기재될 실용신안등록청구범위의 균등범위 내에서 다양한 수정 및 변형이 가능함은 물론이다.As described above, although the present invention has been described by means of a limited embodiment and drawings, the present invention is not limited thereto, and should be understood by those of ordinary skill in the art to which the present invention pertains. Various modifications and variations can be made within the equivalent scope of the utility model registration claims to be described below.

본 발명에 따르면, 어린이들이 콘센트의 접속단자를 접촉하여 발생되는 전기안전사고를 미연에 예방하며, 콘센트에 견고하게 결합된 플러그를 사용자의 의도에 부합하도록 작은 힘으로도 정확히 착탈시킬 수 있게 되어, 오작동율을 현저히 줄일 수 있는 효과가 있다.According to the present invention, children can prevent electrical safety accidents caused by contacting the connection terminal of the outlet in advance, and the plug firmly coupled to the outlet can be detached with a small force to meet the user's intention, There is an effect that can significantly reduce the malfunction rate.
