상기한 바와 같은 목적을 달성하고 종래의 결점을 제거하기 위한 과제를 수행하는 본 발명의 전자파 차단기는 전원 라인의 한쪽이 접지가 되어 있다는 원리에 착안해서 전원 라인 AC1과 AC2 중 어떠한 쪽이 접지와 연결 되어 있는지 찾아내어서 그곳에 접지선을 연결해 줌으로써 전자파를 차단할 수 있는 것이다.The electromagnetic wave breaker of the present invention, which achieves the above object and accomplishes the problem of eliminating the conventional drawback, is connected to the ground of any one of the power lines AC1 and AC2 based on the principle that one side of the power line is grounded. You can cut off the electromagnetic waves by finding out if there is a connection and connecting a ground wire to it.
이하 본 발명의 실시예인 구성과 그 작용을 첨부도면에 연계시켜 상세히 설명하면 다음과 같다.Hereinafter, the configuration and the operation of the embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도 1 은 본 발명에 따른 전자파 차단기 회로도로서,1 is a circuit breaker circuit diagram according to the present invention,
도 1 에 도시된 바와 같이 본 발명의 전자파 차단기는 전자제품에 전원을 공급하는 양단의 교류전원공급단자(AC1)(AC2)에 각각 직렬 연결된 저항(R2)(R3)과,As shown in FIG. 1, the electromagnetic wave breaker of the present invention includes resistors R2 and R3 connected in series to AC power supply terminals AC1 and AC2 at both ends for supplying power to electronic products.
전자제품의 접지단자(G1)와 직렬 연결된 스위치(SW1)와 시정수회로(R1,C2) 사이에 직렬 연결되는 피티씨(PTC)(RT1)와,PTC (RT1) connected in series between the switch (SW1) and time constant circuit (R1, C2) connected in series with the ground terminal (G1) of the electronic product,
과전류에 의한 사용자의 감전 방지용 저항(R4,R5)를 통해 상기 피티씨(RT1)와 시정수회로(R1,C2)사이에 접속되어 전자파의 차단 여부를 경고하는 네온램프(LP1)와,Neon lamp (LP1) connected between the PTC (RT1) and the time constant circuit (R1, C2) through the resistance (R4, R5) for preventing electric shock of the user due to overcurrent, and warns whether the electromagnetic wave is blocked;
상기 교류전원공급단자(AC1)(AC2)에 연결된 저항(R2)(R3)과 제1단 및 제3단이 각각 연결되고 상기 피티씨(RT1)에 직렬 연결된 시정수회로(R1,C2)에 제2단이 연결되며 상기 네온램프(LP1)과 직렬 연결된 저항(R4)과 제4,5단이 연결되어 볼륨스위치를 통하여 저항값을 조절하는 가변저항(VR1)으로 구성되는 것이다.The resistors R2 and R3 connected to the AC power supply terminals AC1 and AC2 and the first and third terminals are respectively connected to time constant circuits R1 and C2 connected in series to the PTC RT1. A second stage is connected, and the resistor R4 connected in series with the neon lamp LP1 and the fourth and fifth stages are connected to each other, and are configured as a variable resistor VR1 for adjusting a resistance value through a volume switch.
여기서, 상기 교류전원공급단자(AC1)(AC2)에 각각 직렬 연결된 저항(R2)(R3)은 전자제품의 구동전원으로부터 전자파 차단율과 가변저항(VR1)을 보호하는 것이고, 상기 피티씨(RT1)는 시정수회로(R1,C2)의 시정수에 의해 동작시간이 결정되며 접지선과 전원 라인의 잘못된 접지라인으로 인한 회로보호 소자인 것이다.Here, the resistors R2 and R3 connected in series to the AC power supply terminals AC1 and AC2 respectively protect the electromagnetic wave blocking rate and the variable resistor VR1 from the driving power of the electronic product. The operation time is determined by the time constants of the time constant circuits R1 and C2 and is a circuit protection device due to an incorrect ground line of the ground line and the power line.
그리고 상기 네온램프(LP1)는 전자파 발생시 사람의 알파파와 작용하여 빛을 발산하는 소자로써 사용자가 가변저항(VR1)을 네온램프(LP1)가 빛을 발생하지 않는 위치에 돌려줌으로써 전자파 차단 여부를 확인할 수 있는 것이다.The neon lamp LP1 is a device that emits light by acting on an alpha wave of a person when an electromagnetic wave is generated. The user turns the variable resistor VR1 to a position where the neon lamp LP1 does not generate light to check whether the electromagnetic wave is blocked. It can be.
즉, 상기와 같이 구성된 본 발명의 전자파 차단기의 동작설명을 하면 다음과같다.That is, the operation of the electromagnetic wave breaker of the present invention configured as described above is as follows.
사용자가 전원 콘센트에 본 발명의 전자파 차단기가 내장된 전원코드를 전자제품에 연결하여 전원이 공급되면 사용자는 네온램프(LP1)에 신체의 일부를 접촉하여 네온램프(LP1)가 점등되는지를 확인한다.When the user connects the power cord with the electromagnetic wave breaker of the present invention to the electrical outlet and the power is supplied, the user contacts a part of the body with the neon lamp LP1 to check whether the neon lamp LP1 is turned on. .
만약, 네온램프(LP1)가 점등되면 교류전압단자(AC1)(AC2)로부터 공급되는 교류전원이 네온램프를 거쳐 전자제품의 접지단자(G1)가 접지기준전압(0V)을 갖는 단자에 연결되지 않아 접지되지 못함으로써 전자파가 발생되고 있음을 나타낸다.If the neon lamp LP1 is turned on, AC power supplied from the AC voltage terminals AC1 and AC2 is not connected to the terminal having the ground reference voltage (0 V) via the neon lamp. Therefore, it cannot be grounded, indicating that electromagnetic waves are being generated.
이때 가변저항(VR1)의 특성을 이용하여 가변저항 1단과 2단 사이의 저항과, 3단과 2단 사이의 저항값을 조절함으로써 가변저항(VR1) 2단에서의 전압이 낮아지면 접지단자(G1)를 통하여 전자제품에서 전송되는 부하잔류전원이 2단측의 전압으로 접지되어 동작되는 것이다. 여기서 시정수회로(R1,C2)의 시정수에 의해 동작시간이 결정되는 피티씨(RT1)는 접지선과 전원 라인의 잘못된 접지라인으로 인한 회로를 보호하는 것이고 네온램프(LP1)를 통한 접지단자(G1)로 전원이 공급되지 않음으로서 네온램프가 소등되어 전자파 차단 여부를 확인할 수 있는 것이다.At this time, by adjusting the resistance value between the first and second stages of the variable resistor and the resistance value between the third and second stages using the characteristics of the variable resistor VR1, the ground terminal G1 when the voltage at the second stage of the variable resistor VR1 is lowered. The load residual power transmitted from the electronic product through) is grounded to the voltage of the second stage. Here, PTC RT1, whose operation time is determined by time constants of time constant circuits R1 and C2, protects a circuit caused by an incorrect ground line of a ground line and a power line, and is connected to a ground terminal through a neon lamp LP1. Since the power is not supplied to G1), the neon lamp is turned off to check whether electromagnetic waves are blocked.
본 발명은 상술한 특정의 바람직한 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형실시가 가능한 것은 물론이고, 그와 같은 변경은 청구범위 기재의 범위 내에 있게 된다.The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.
상기와 같이 구성되고 동작하는 본 발명의 전자파 차단기는 네온램프를 통하여 전자파의 발생 유무를 용이하게 확인할 수 있고, 간단한 전자파차단스위치(가변저항)의 조작을 통하여 전자파를 효과적으로 차단할 수 있으며, 전자파 차단기의 구조가 간단하여 소형으로 제작이 가능함으로서 전선이나 전원 플러그 등 전원코드에 용이하게 설치할 수 있는 유용한 발명이다.The electromagnetic wave breaker of the present invention constructed and operated as described above can easily check the occurrence or absence of the electromagnetic wave through the neon lamp, and can effectively block the electromagnetic wave through a simple operation of the electromagnetic wave cutoff switch (variable resistor). It is a useful invention that can be easily installed in a power cord such as an electric wire or a power plug because the structure is simple and can be manufactured in a small size.
