Description

개량된 110V·220V 겸용 플러그의 감전 방지장치Electric shock prevention device of improved 110V and 220V plug

본 고안은 110V·220V 겸용 플러그에 관한 것으로, 더욱 상세하게는 콘센트에 110V·220V 접속단자 중 어느 하나를 콘센트에 결합하였을 때, 콘센트에 결합되지 않은 접속단자에도 전류가 흐르게 된다. 따라서, 부주의로 접속단자를 만지면 감전되게 됨으로 이러한 감전사고를 방지하기 위해 개량된 110V·220V 겸용 플러그의 감전 방지장치에 관한 것이다.The present invention relates to a 110V-220V dual plug, and more specifically, when one of the 110V-220V connection terminal is connected to the outlet, the current flows to the connection terminal that is not connected to the outlet. Accordingly, the present invention relates to an electric shock prevention device for a 110 V 220 V plug which is improved to prevent such an electric shock by inadvertently touching the connection terminal.

일반 가정이나 사무실 등에 공급되는 전원은 110V·220V가 함께 공급되고 있음으로 하여 대부분의 가전제품도110V·220V 겸용으로 생산되므로 사용자는 임으로 전압에 맞게 제품의 전압을 조절하여 사용하고 있다.Since 110V and 220V are supplied together with power supply to general homes and offices, most home appliances are also produced as both 110V and 220V, so users can adjust the voltage of the product according to the voltage.

또한, 사용자가 전압에 따라 선택적으로 사용할 수 있도록 안전장치가 구비된 110V·220V 겸용 플러그가 생산 보급되고 있다.In addition, 110V and 220V dual plugs with safety devices are widely available for users to selectively use according to voltage.

종래의 안전장치가 구비된 110V·220V 겸용 플러그는 대한민국 실용신안공고번호 제88-3306호(명칭: 110V·220V 겸용 플러그)에 상세히 개시되어 있는데, 이를 첨부된 도면을 참조하여 설명하면 다음과 같다.110V, 220V plug with a conventional safety device is disclosed in detail in Korean Utility Model Publication No. 88-3306 (name: 110V, 220V plug), which will be described below with reference to the accompanying drawings. .

Then, a pair of conductive terminals 31a, 31b, 31c, and 31d are provided on the surface to which the connection terminals 12a, 12b and 14a, 14b are coupled.

터미널(31a, 31b, 31c, 31d)은 제4a도에 도시된 바와 같이, 플러그(10)내에 접속단자들과 전기적으로 연결되어 있다.Terminals 31a, 31b, 31c, and 31d are electrically connected to connection terminals in plug 10, as shown in FIG. 4A.

터미널(31a, 31b, 31c, 31d)중 어느 하나 즉, 110V용 접속단자(12a, 12b)가 결합된 표면에 결합되어진 터미널(31c)은 220V용 접속단자(14a, 14b)중 어느 하나 즉, 14a와 전기적으로 연결되어 있고, 다른 터미널 즉, 220V용 접속단자(14a, 14b)가 결합된 표면에 결합되어진 터미널(31a)은 110V용 접속단자 중 어느 하나 즉, 12a와 전기적으로 연결되어 있다.One of the terminals 31a, 31b, 31c, and 31d, that is, the terminal 31c coupled to the surface on which the 110V connection terminals 12a and 12b are coupled, is one of the 220V connection terminals 14a and 14b. The terminal 31a, which is electrically connected to 14a and coupled to another terminal, that is, the surface on which the 220V connection terminals 14a and 14b are coupled, is electrically connected to any one of the 110V connection terminals, that is, 12a.

그리고, 나머지 터미널(31b, 31d)은 전술한 각각의 터미널(31a, 31c)과 이격되게 각각의 110V용 접속단자(12a, 12b) 및 220V용 접속단자(14a, 14b)가 결합된 면에 서로 전기적으로 연결되게 결합되어 있다. 각각의 터미널(31b, 31d)에 전기적으로 연결된 전도체에는 케이블(c)의 전선(c1)이 전기적으로 연결되어 있다.The remaining terminals 31b and 31d are mutually spaced on the surface where the respective 110V connecting terminals 12a and 12b and the 220V connecting terminals 14a and 14b are spaced apart from the respective terminals 31a and 31c described above. Are electrically connected. The electric wire c1 of the cable c is electrically connected to the conductor electrically connected to each of the terminals 31b and 31d.

아울러, 터미널과 전기적으로 연결되지 않은 나머지 110V용 접속단자(14b) 및 220V용 접속단자(12b)는 플러그(10)내에 전도체에 의해 전기적으로 연결되어 있고, 그 전도체에 전술한 케이블(c)의 나머지 전선(c2)이 전기적으로 연결되어 있다. 플러그(10)는 그 외부 표면에 걸림홈(16)이 대칭되게 형성되어 있다.In addition, the remaining 110V connection terminal 14b and 220V connection terminal 12b, which are not electrically connected to the terminal, are electrically connected to each other by a conductor in the plug 10, and the cable (c) described above is connected to the conductor. The remaining wire c2 is electrically connected. The plug 10 has a locking groove 16 symmetrically formed on an outer surface thereof.

안전커버(20)는 전술한 플러그(10) 표면에 형성된 걸림홈(16)에 착탈가능하게 결합되는 스냅피트(22)를 구비하고 있으며, 스냅피트(22)가 부설된 면에 전술한 110V용 접속단자(12a, 12b) 및 220V용 접속단자(14a, 14b)를 수용하는 삽입구(24, 26)가 형성되어 있고, 전술한 한 쌍의 터미널(31a, 31b, 31c, 31d)이 전기적으로 통하도록 접속되는 스위치(38)가 부착되어 있다.Safety cover 20 is provided with a snap fit 22 detachably coupled to the engaging groove 16 formed on the surface of the plug 10 described above, for the 110V mentioned above on the surface on which the snap fit 22 is installed Insertion holes 24 and 26 are formed to accommodate the connection terminals 12a and 12b and the connection terminals 14a and 14b for 220V, and the pair of terminals 31a, 31b, 31c and 31d described above are electrically connected. And a switch 38 connected to each other.

이와 같이 구성된 본 고안에 따른 개량된 110V·220V 겸용 플러그의 감전 방지장치에 대한 작용과 작용효과를 설명하면 다음과 같다.Referring to the operation and effects of the electric shock prevention device of the modified 110V-220V dual plug according to the present invention configured as described above are as follows.

제4a도에는 본 고안에 따른 플러그의 220V용 접속단자가 콘센트에 결합된 상태의 단면도가 도시되어 있는데, 도면에서 알 수 있는 바와 같이, 콘센트(32)에 삽입된 일측의 220V용 접속단자(14a)는 110V용 접속단자(12a, 12b)의 표면에 결합된 터미널(30c)로 전류가 유도되게 되며, 그 터미널(30c)은 안전커버(20)가 플러그(10)에 결합될 때, 자동적으로 접속되는 스위치(38)에 의해 인접한 터미널(30d)과 전기적으로 연결되어진다.Figure 4a is a cross-sectional view of the 220V connection terminal of the plug according to the present invention coupled to the outlet is shown, as can be seen, the 220V connection terminal 14a of one side inserted into the outlet 32 ) Is the current is induced to the terminal 30c coupled to the surface of the connection terminal (12a, 12b) for 110V, the terminal (30c) is automatically when the safety cover 20 is coupled to the plug 10, It is electrically connected to an adjacent terminal 30d by a switch 38 to be connected.

따라서, 스위치(38)에 의해 터미널(30c, 30d)과 전기적으로 연결되어 전류는 전도체를 따라 케이블(c)의 전선(c1)으로 유도된다.Thus, the switch 38 is electrically connected to the terminals 30c and 30d so that a current is led along the conductor to the wire c1 of the cable c.

또한, 콘센트(32)에 삽입된 타측의 220V용 접속단자(14b)와 110V용 접속단자(12b)와 케이블(c)의 전선(c2)에 전류가 유도되게 된다.In addition, a current is induced to the other terminal 220V connecting terminal 14b, 110V connecting terminal 12b inserted into the outlet 32, and the wire c2 of the cable c.

따라서, 케이블(c)로 전류가 유도되어 케이블(c)이 결합된 특정제품에 전원이 제공되게 된다. 만일, 전술한 바와 같은 안전커버(32)를 플러그(10)에서 분리시키면 스위치(38)가 터미널(30c, 30d)에서 떨어지게 되어 전류의 흐름이 차단됨으로 감전의 위험이 전혀 발생하지 않는다.Thus, current is induced into the cable c so that power is supplied to the specific product to which the cable c is coupled. If the safety cover 32, as described above, is removed from the plug 10, the switch 38 is separated from the terminals 30c and 30d so that the flow of current is blocked, so that there is no risk of electric shock.

그러므로, 설사 어린이의 장난이나 부주의로 안전커버가 분리되더라도 노출되어진 접속단자(12a, 12b)에는 전류가 흐르지 않기 때문에 누전 혹은 감전의 우려가 없다.Therefore, even if the safety cover is removed due to mischief or carelessness of a child, no current flows through the exposed connection terminals 12a and 12b, so there is no fear of an electric shock or an electric shock.

제4b도에는 본 고안에는 따른 플러그의 110V 접속단자가 콘센트에 결합된 상태의 단면도가 도시되어 있는데, 제4a도에서 설명한 바와 같이 전기적인 전류의 흐름도 동일하며, 그 작용예도 동일하다. 단지 안전커버를 220V용 접속단자에 결합한 것과 콘센트에 110V용 접속단자를 삽입하였다는 것 이외에는 모두 전술한 바와 같다. 물론 스위치(38)는 터미널(31a, 31b)에 접속된다.Figure 4b is a cross-sectional view of a state in which the 110V connection terminal of the plug according to the present invention is coupled to the outlet, as shown in FIG. It is as described above except that only the safety cover is coupled to the 220V connection terminal and the 110V connection terminal is inserted into the outlet. Of course, switch 38 is connected to terminals 31a and 31b.

이상에서 설명한 바와 같이 본 고안에 따른 개량된 110V·220V 겸용 플러그의 감전 방지장치는 전원이 유도된 상태에서 플러그로부터 안전커버가 분리되면 자동적으로 전원이 차단되어 플러그에 의해 감전사고를 방지하는 효과를 얻을 수 있다.As described above, the improved electric shock prevention device of the combined 110V and 220V plug according to the present invention is automatically cut off when the safety cover is removed from the plug while the power is induced, thereby preventing the electric shock by the plug. You can get it.
