본 고안은 220V 프러그 및 110V 아덥터 프러그에 관한 고안인 것이다.The present invention relates to a 220V plug and a 110V adapter plug.

종래의 110V용 아덥터 프러그는 220V 프러그에 바로 꽂아 110V 콘센트에 사용하는 것들로서 사용기기 내부의 절환스위치를 반드시 사용전압에 맞추워 절환해야 하는 불편이 있었으며, 내부기기를 110V로 전환하고 110V용 아덥터 프러그를 꽂아 사용하다가 우연한 경우 아덥터 프러그가 제거되면 220V 프러그만 남게 되어 그대로 220V에 꽂아 사용할 수 있게 되는 위험이 있었던 것이다.Conventional 110V adapter plugs are plugged directly into 220V plugs and used for 110V outlets.They had to be inconvenient to switch by switching the switch inside the equipment to the required voltage.The internal equipment was switched to 110V and the 110V adapter plug was used. If you accidentally plug in and use the adapter, if the adapter is removed, only 220V plugs remain and there is a risk that the plug can be used at 220V.

본 고안은 이러한 폐단을 제거키 위하여 즉, 기기내부의 절환스위치(사용전압에 맞추는)의 절환의 필요없이 220V 프러그 하나만 있는 상태에서는 220V에, 그리고 110V용 아덥터 프러그를 삽입하며 110V에 각각 사용할 수 있도록 내부회로가 구성되게 한 것으로서 도면에 의해 상세히 설명하면 다음과 같다.The present invention eliminates these closed ends, that is, 220V plugs with only one 220V plug without the need to change the switching switch (in accordance with the operating voltage) inside the device, and 110V can be used for 110V plugs. When the internal circuit is configured as described in detail by the drawings as follows.

제1도에서와 같이 공지의 220V용 프러그의 접촉 핀쪽 중앙에 삽입구(7)를, 그리고 내부에는 공간부(6)를 형성하여 전기접점(2")(2"') 및 접점(3")(3"')이 접합된 금속탄성체(2)(3)를 접점(2")(3")가 서로 접하게 착설하고, 금속탄성체(2)(3)이 탄성운동을 할때 접점(2"')(3"')와 각각 단락될 수 있도록 접점(1"')(4"')를 각각 형성고착하여 접촉핀(1)(4)과 전선(1")(4"')로 각각 연결하며, 접촉핀(1)(4) 및 금속탄성체(2)(3)를 비닐 전선(1')(4')(2')(3')로 각각 연결하여 전선코드로 하고, 한편, 220V 프러그(5)와 접촉되는 110V용 아덥터 프러그는 공지의 110V용 아덥터 프러그의 220V 접촉핀 접촉구중앙에, 제1도의 220V 프러그 접속핀 중앙의 삽입구(7)에 삽입되고, 삽입되면 내부에서 금속탄성체를 좌우로 탄성운동을 시킬 수 있는 절연 삽입봉(7')를 형성하여서 제2도와 같이 하여서 된 것이다.As shown in Fig. 1, an insertion hole 7 is formed in the center of the contact pin side of the known 220V plug and a space 6 is formed therein, so that the electrical contacts 2 ", 2" 'and the contact 3 "are formed. (2 "and 3") are attached to each other and the metal elastic bodies (2) and (3 ") are bonded to each other, and the metal elastic bodies (2) and (3) are elastically moved. Contacts 1 "'and 4"' are formed so as to be shorted with '3' ', respectively, and contact pins 1 and 4 and wires 1 and 4 "respectively. Connect the contact pins (1) (4) and the metal elastic bodies (2) (3) with vinyl wires (1 '), (4'), (2 ') and (3'), respectively, The 110V adapter plug in contact with the 220V plug 5 is inserted in the center of the 220V contact pin contact hole of the known 110V adapter plug, and inserted into the insertion hole 7 in the center of the 220V plug connecting pin of FIG. By forming an insulating insertion rod (7 ') capable of elastic movement of the elastic body to the left and right, as shown in FIG.

이들의 동작원리를 설명하면, 제1도와 같이 220V 프러그만 있을시는 금속탄성체(2)(3)의 탄력에 의해 접점(2"')(3"')는 서로 접하게 되어 제3도와 같이 전류는 접촉핀(1)→코드내부 전선(1')→부하(L1)→전선(3')→금속탄성체(3)→접점(3")→접점(2")→금속탄성체(2)→전선(2")→부하(L2)→전선(4')→접촉핀(4)로 흐를 수 있게 되어 부하(L1)(L2)가 각각 110V용인 경우 220V에 사용할 수 있게 되는 것이다.When explaining the operation principle, when only 220V plug as shown in Fig. 1, the contacts 2 "'and 3"' are brought into contact with each other due to the elasticity of the metal elastic bodies 2 and 3, so that the current is as shown in Fig. 3. Silver contact pin (1) → Cord inner wire (1 ') → Load (L 1 ) → Wire (3') → Metal elastomer (3) → Contact (3 ") → Contact (2") → Metal elastomer (2) → wire (2 ") → load (L 2 ) → wire (4 ') → contact pin (4) can flow, so if the load (L 1 ) (L 2 ) for each 110V can be used for 220V .

한편, 110V용 아덥터 프러그(10)를 220V 프러그에 삽입하면 접촉핀(1)은 접촉구(8)에 접촉핀(4)은 접촉구(9)에 각각 삽입되어 접촉핀(8')(9')와 110V용 아덥터 프러그몸체(10)의 내부에서 연결되며, 또한 돌설된 절연삽입봉(7')은 삽입구(7)에 삽입되면서 금속탄성체(2)(3)를 좌우로 각각 벌리게 되어 접점(2")(3")은 떨어지게 되고, 접점(2"')(3"')는 접점(1"')(4"')와 각각 접하게 되어 부하(L1)(L2)는 병렬연결이 되어, 110V에 사용할 수 있게 되는 것이다.On the other hand, when the 110V adapter plug 10 is inserted into the 220V plug, the contact pin 1 is inserted into the contact hole 8, and the contact pin 4 is inserted into the contact hole 9, respectively. ') And the internal insulation plug body 10 for 110V, and the insulated insertion rod 7', which is protruding, is inserted into the insertion hole 7 and the metal elastic bodies 2 and 3 are opened to the left and right, respectively. (2 ") (3") are dropped, and the contacts 2 "'and 3"' are in contact with the contacts 1 "'and 4"' respectively so that the load L 1 and L 2 are parallel. The connection is made, and it can be used for 110V.

한편, 본 고안은 코드전선(1')(2')(3')(4')가 있어 공지의 겸용 코드전선(2선식)보다 전선(동)의 소비를 갖어오는 것처럼 생각되나 부하(L1)는 코드전선(1)(3') 및 부하(L2)는 코드전선(2)(4')에 각각 연결되어 있음으로 코드전선(1')(2')(3')(4')는 부하(L1) 또는 부하(L2)의 전류만 흐르게 되어, 공지의 겸용 전선이 110V 사용시 전류는 부하(L1)(L2)의 합한 전류가 허용되는 굵기의 전선이어야 함에 반하여 본 고안에서는 그 굵기의 반이면 족하게 되어 전선(동)의 소비가 없는 것이다.On the other hand, the present invention has cord wires (1 '), (2'), (3 ') and (4'). 1 ) the cord wires (1) (3 ') and the load (L 2 ) are connected to the cord wires (2) (4'), respectively. ') Flows only the current of the load (L 1 ) or load (L 2 ), when the known combined wire 110V is used, the current should be a wire of the thickness that allows the combined current of the load (L 1 ) (L 2 ) In this invention, half of the thickness is enough, and there is no consumption of electric wires (copper).

이와 같은 본 고안은 110V, 220V겸용 기기(기기의 내부회로가 각각 110V용의 쌍 회로의 여하한 회로)에 널리 사용될 수 있는 것으로서 기기내부의 110V, 220V 절환스위치의 절환이 필요없이 110V용 아덥터 프러그만 삽입하면 자동적으로 110V에, 그리고 아덥터 프러그만 제거하면 역시 자동으로 220V에 사용될 수 있음으로 기기의 소손등 위험없이 사용할 수 있는 대단히 유용한 고안인 것이다.The present invention can be widely used for 110V, 220V combined devices (internal circuit of the device, any circuit of a pair circuit for 110V respectively), 110V, 220V adapter plug without the need to switch between 110V, 220V switching switch inside the device It is a very useful design that can be used at 110V automatically by inserting it and automatically used at 220V only by removing the adapter plug.
