본 발명은 플러그를 내부플러그와 외부플러그로 구분하여 구성함으로서 100볼트용 또는 220볼트용으로 선별하여 사용할 수 있도록 된 100볼트/220볼트 절환용 플러그에 관한 것이다.The present invention relates to a 100 volt / 220 volt switching plug that can be used to select the 100 volts or 220 volts by separating the plug into an internal plug and an external plug.

종래의 플러그는 100볼트 전용 또는 220볼트 전용으로 되어 있었기 때문에 별도의 전원선과 플러그를 준비해 두어야 하는 불편이 있었다.Since the conventional plug is dedicated to 100 volts or 220 volts, it is inconvenient to prepare a separate power line and plug.

본 발명은 상기와 같은 불편을 해소하기 위하여 플러그를 외부플러그와 내부플러그로 구분하며, 조립할 수 있도록 하고 내부플러그에 100볼트용과 220볼트용의 단자를 형성하여 선택적으로 사용할 수 있도록 함으로서 하나의 플러그로 100볼트 및 220볼트에 겸용할 수 있도록 함에 목적이 있다.The present invention is to separate the plug into an external plug and an internal plug in order to solve the above inconvenience, to be assembled and to form a terminal for 100 volts and 220 volts in the inner plug can be selectively used as one plug The purpose is to be compatible with 100 volts and 220 volts.

본 발명을 첨부된 예시도면과 함께 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings.

본 발명은 외부플러그(1)의 상·하부케이스(2), (3)내에 내부단자(4)를 형성하고, 상부케이스(2)에는 스프링(5)에 탄지되어 축(6)을 중심으로 회동될 수 있는 고정편(7)을 설치하며, 내부플러그(8)를 외부플러그(1)의 개구부(9)로 삽입하여 결합할 수 있도록 하되, 내부플러그(8)의 상·하부케이스(10), (11)내에는 내부단자(12)를 설치하여 외향돌부(13)가 상·하부케이스(10), (11)의 측면 천공부(14)로 노출되도록 하며, 상부케이스(10)의 상면에는 장방형의 걸림홈(15)을 형성한 것이다.The present invention forms the inner terminal (4) in the upper and lower cases (2), (3) of the outer plug (1), the upper case (2) is supported by a spring (5) centered around the shaft (6) The fixing piece 7 which can be rotated is installed, and the inner plug 8 is inserted into the opening 9 of the outer plug 1 to be coupled, but the upper and lower cases 10 of the inner plug 8 The inner terminal 12 is installed in the 11 and 11 so that the outward protrusion 13 is exposed to the upper and lower cases 10 and the side perforations 14 of the 11, and the upper case 10 A rectangular locking groove 15 is formed on the upper surface.

도면중 미설명부호 16은 고정편(7)의 누름부, 17은 고정편(7)의 후크부, 18은 고정편(7)을 설치하기 위한 고정편 설치호울, 19는 내부단자(4)의 내향돌부, 20은 100볼트용 접속단자, 21은 220볼트용 접속단자, 22는 리드선, 23은 결합 보울트이다.In the drawings, reference numeral 16 is a pressing part of the fixing piece 7, 17 is a hook portion of the fixing piece 7, 18 is a fixing piece mounting hole for installing the fixing piece 7, and 19 is an inner terminal 4. The inward projection of 20 is a connection terminal for 100 volts, 21 is a connection terminal for 220 volts, 22 is a lead wire, and 23 is a coupling bolt.

본 발명은 예시도면 제5도 또는 제6도와 같은 상태로 내부플러그(8)를 외부플러그(1)내에 결합하여 사용하는 것으로서, 내부플러그(8)를 외부플러그(1)내에 결합하게 되면, 외부플러그(1)내의 내부단자(4)와 내부플러그(8)내의 내부단자(12)가 접속된다. 즉, 내부단자(4)의 내향돌부(19)가 탄성을 갖고 내측으로 돌출되어 있으므로 이 부분이 내부플러그(8)의 외향돌부(13)에 밀접되는 것이다.The present invention uses the inner plug 8 in the outer plug 1 in the state shown in FIG. 5 or FIG. 6, and when the inner plug 8 is coupled in the outer plug 1, The internal terminal 4 in the plug 1 and the internal terminal 12 in the internal plug 8 are connected. That is, since the inward protrusion 19 of the inner terminal 4 is elastic and protrudes inward, this portion is in close contact with the outward protrusion 13 of the inner plug 8.

내부플러그(8)를 외부플러그(1)로부터 분리하고자 할때는 고정편(7)의 누름부(16)를 외부에서 누르면 축(6)을 중심으로 스프링(5)에 탄지되어 있던 고정편(7)이 회전되면서 걸림홈(15)에 걸려있던 후크부(17)가 걸림홈(15)으로부터 이탈되므로 용이하게 내부플러그(8)를 외부플러그(1)로부터 분리할 수 있게 된다.When the inner plug 8 is to be detached from the outer plug 1, when the pressing portion 16 of the fixing piece 7 is pushed from the outside, the fixing piece 7 supported by the spring 5 around the shaft 6 is held. Since the hook 17 is caught in the locking groove 15 while being rotated is separated from the locking groove 15, the inner plug 8 can be easily separated from the outer plug 1.

본 발명은 외부플러그(1)로부터 내부플러그(8)를 결합, 분리할 수 있도록 되어 있어서, 필요에 따라 100볼트용 접속단자(20) 또는 200볼트용 접속단자(21)를 외측으로 돌설시켜 선택적으로 사용할 수 있는 효과가 있다.According to the present invention, the inner plug 8 can be coupled and separated from the outer plug 1, so that the 100-volt connection terminal 20 or the 200-volt connection terminal 21 can be turned outward as needed. It can be used as an effect.
