일상생활에서 사용되는 전기, 전자제품이 증가함에 따라서, 제한된 수의 전원??에 더 많은 전자제품을 연결하여 전원을 인가하기 위하여 제안된 것이 멀티 콘센트로서, 보통 멀티콘센트는 하나의 플러그와 둘 이상의 소켓을 구비하고, 상기 플러그와 둘 이상의 소켓은 병렬로 연결하여 구성되며, 상기 멀티콘센트의 플러그를 발전소의 전력선에 연결되어 항시 상용전원이 인출 가능한 고정된 전원소켓에 인가하면, 해당 교류전원이 상기 멀티콘센트의 플러그에 연결된 전원소켓들로 인가되어, 둘 이상의 전자제품에 동시에 전원을 인가할 수 있게 된다.As the number of electrical and electronic products used in everyday life increases, a multi-outlet has been proposed to connect more electronic products to a limited number of power sources, usually with one plug and two or more plugs. And a plug, and the plug and two or more sockets are connected in parallel, and when the plug of the multi-outlet is connected to a power line of a power plant and applied to a fixed power socket capable of drawing a commercial power at all times, the corresponding AC power is It is applied to power sockets connected to the plugs of the multi-outlets, so that power can be applied to two or more electronic products at the same time.

그리고, 그 사용이 보편화되어 있는 컴퓨터는 프린터, 스캐너, 스피커등 다양한 주변장치가 연결되어 함께 사용되며, 컴퓨터 뿐만 아니라 이런 많은 주변기기에 동시에 전원을 공급하기 위해서 멀티콘센트가 많이 이용된다.In addition, the computer is widely used, and various peripheral devices such as printers, scanners, and speakers are connected and used together, and multi-outlets are widely used to supply power to not only computers but also many such peripheral devices at the same time.

If you do not use the computer, you must turn off each device. If you do not use the computer, turn off the computer. Often throw away.

그렇기 때문에, 각 주변장치로 계속 인가되는 대기전력에 의해 불필요한 전력소모가 존재하며, 이러한 전력낭비는 에너지문제가 심각한 현대에 있어 개선되어야 할 문제이다.Therefore, unnecessary power consumption exists due to the standby power continuously applied to each peripheral device, and this waste of power is a problem that should be improved in the present day when the energy problem is serious.

The input unit is also configured to be combined with a PC power cord.

도 1은 본 발명에 따른 절전형 멀티 콘센트의 구성을 블럭도로서, 외부 상용교류전원을 입력받는 AC전원입력부(11)와, 상기 AC전원입력부(11)를 통해 인가된 상용교류전원을 외부 장치로 인가하기 위한 PC전원인가부(12)와, 상기 AC전원입력부(11)에서 PC전원인가부(12)로 흐르는 전류 량을 검출하는 전류검출부(14)와, 상기 전류검출부(14)에서 검출된 전류검출치에 따라서 AC전원입력부(11)를 통해 입력된 전원을 다수의 AC전원소켓으로 이루어진 멀티콘센트부(15)에 인가하거나 차단시키는 교류제어부(13)와, 상기 교류제어부(13)를 통해 상기 AC전원입력부(11)에 연결되는 다수의 AC전원소켓으로 이루어진 멀티콘센트부(15)를 구비한다.1 is a block diagram of a power-saving multi-outlet according to the present invention, the AC power input unit 11 for receiving an external commercial AC power and the commercial AC power applied through the AC power input unit 11 to an external device. PC power supply unit 12 for applying, a current detection unit 14 for detecting the amount of current flowing from the AC power input unit 11 to the PC power supply unit 12, and detected by the current detection unit 14 In accordance with the current detection value through the AC power input unit 11 through the AC control unit 13 for applying or blocking to the multi-outlet unit 15 consisting of a plurality of AC power sockets, and through the AC control unit 13 It is provided with a multi-outlet unit 15 consisting of a plurality of AC power sockets connected to the AC power input unit 11.

상기와 같이 구성된 절전형 멀티 콘센트는 다음과 같이 동작한다.The power-saving multi-outlet configured as described above operates as follows.

전류검출부(13)는 상기 AC전원입력부(11)와 PC전원인가부(12)를 연결하는 전원라인(도선)에 설치되어 상기 AC전원입력부(11)에서 PC전원인가부(12)로 흐르는 전류에 비례한 전압을 출력하는 CT(Current Transformer) 전류센서(13a)를 포함하여 이루어진 것으로서, 항상 상기 AC전원입력부(11)와 PC전원인가부(12) 사이에 흐르는 전류 량을 검출한다.The current detection unit 13 is installed on a power line (conductor) connecting the AC power input unit 11 and the PC power supply unit 12 to flow the current from the AC power input unit 11 to the PC power supply unit 12. It includes a CT (Current Transformer) current sensor (13a) for outputting a voltage proportional to the, and always detects the amount of current flowing between the AC power input 11 and the PC power supply 12.

그리고, 교류제어부(14)는 상기 전류검출부(13)의 출력전압에 따라 동작하는 것으로, 상기 AC전원입력부(11)와 PC전원인가부(12) 사이에 흐르는 전류가 없어 상기 전류검출부(13)로부터 출력되는 전압이 없는 경우, 상기 AC전원입력부(11)로 인가된 전원이 멀티콘센트부(15)에 인가되지 않도록 전원라인을 단락 시키고, 상기 AC전원입력부(11)와 PC전원인가부(12) 사이에 흐르는 전류가 있어 상기 전류검출부(13)로부터 소정의 전압이 출력되는 경우, 상기 AC전원입력부(11)로 인가된 전원이 멀티콘센트부(15)로 인가되도록 전원라인을 연결시킨다.The AC controller 14 operates according to the output voltage of the current detector 13, and there is no current flowing between the AC power input 11 and the PC power supply 12, so that the current detector 13 If no voltage is output from the AC power input unit 11, the power line is shorted so that the power applied to the AC power input unit 11 is not applied to the multi-outlet unit 15, and the AC power input unit 11 and the PC power supply unit 12 When there is a current flowing between) and a predetermined voltage is output from the current detection unit 13, the power line is connected so that the power applied to the AC power input unit 11 is applied to the multi-outlet unit 15.

상기에서, PC전원인가부(12)는 퍼스널컴퓨터 본체에 구비된 전원플러그와 결합되고, 상기 AC전원입력부(11)는 PC전원코드의 소켓과 결합되는 형태로 이루어지며, 멀티콘센트부(15)는 일반적인 멀티콘센트와 같이 표준형 전원플러그가 결합될 수 있는 표준 전원소켓들로 이루어진다.In the above, the PC power supply unit 12 is coupled to the power plug provided in the personal computer body, the AC power input unit 11 is made of a form that is coupled to the socket of the PC power cord, the multi-outlet unit 15 The standard consists of standard power sockets that can be combined with standard power plugs, such as multi-outlets.

즉, 상기 PC전원인가부(12)가 퍼스널컴퓨터 본체의 전원소켓(도시생략)에 결합되고, 상기 AC전원인가부(11)가 기존에 상기 퍼스널 컴퓨터 본체의 전원소켓에 연결되던 PC전원코드의 플러그(도시생략)와 결합되고, 상기 PC전원코드의 다른 쪽 플러그가 상용전원이 출력되는 전원소켓에 결합된다.That is, the PC power supply unit 12 is coupled to a power socket (not shown) of the personal computer main body, and the AC power supply unit 11 is connected to a power socket of the personal computer main body. It is coupled with a plug (not shown), and the other plug of the PC power cord is coupled to a power socket through which commercial power is output.

상기 상태에서, 퍼스널 컴퓨터의 전원버튼을 온 시키면, 교류전원이 본 발명에 의한 절전형 멀티콘센트의 AC전원입력부(11) 및 PC전원인가부(12)를 통해 PC본체로 흘러 들어간다.In this state, when the power button of the personal computer is turned on, AC power flows into the PC main body through the AC power input unit 11 and the PC power supply unit 12 of the power saving type multi-outlet according to the present invention.

따라서, 상기 AC전원입력부(11)와 PC전원인가부(12) 사이의 도선에는 소정 레벨이상의 전류가 흐르고, 상기 전류는 전류검출부(13)의 전류센서(13a)에 의해 검출된다. 이때, 전류검출부(13)로부터 상기 AC전원입력부(11)와 PC전원인가부(12) 사이의 도선에 흐르는 전류 치에 비례하는 소정 전압이 출력되고, 이는교류제어부(14)로 입력된다.Therefore, a current of a predetermined level or more flows in the conductive line between the AC power input unit 11 and the PC power applying unit 12, and the current is detected by the current sensor 13a of the current detection unit 13. At this time, a predetermined voltage is output from the current detection unit 13 in proportion to the current value flowing in the conductive line between the AC power input unit 11 and the PC power supply unit 12, which is input to the AC controller 14.

이때, 교류제어부(14)가 동작하여 상기 AC전원입력부(11)와 멀티콘센트부(15)를 연결시키고, 이에 상기 AC전원입력부(11)로 입력된 전원이 상기 PC측으로 뿐만아니라 멀티콘센트부(15)의 각 전원소켓들에게까지 연결되어 해당 전원소켓에 연결된 PC의 주변장치에 전원을 공급한다.At this time, the AC control unit 14 operates to connect the AC power input unit 11 and the multi-outlet unit 15 so that the power inputted to the AC power input unit 11 is connected to the PC side as well as the multi-outlet unit ( It connects to each power socket of 15) and supplies power to the peripheral device of PC connected to the corresponding power socket.

반대로, 퍼스널컴퓨터의 전원버튼을 오프하는 경우, PC본체로부터의 전원차단으로 인해서, 상기 AC전원입력부(11)와 PC전원인가부(12) 사이의 도선에 흐르는 전류는 0이 된다. 이때, 전류검출부(13)로부터 소정레벨 이하, 예를 들어 0V가 교류제어부(14)로 출력되고, 이에, 교류제어부(14)는 AC전원입력부(11)와 멀티콘센트부(15) 사이의 전원인가를 차단시킨다.On the contrary, when the power button of the personal computer is turned off, the current flowing through the conducting wire between the AC power input unit 11 and the PC power applying unit 12 becomes zero due to the power cutoff from the PC main body. At this time, a predetermined level or less, for example, 0 V, is output from the current detector 13 to the AC controller 14, whereby the AC controller 14 supplies power between the AC power input 11 and the multi-concentrator 15. Block authorization

따라서, 퍼스널 컴퓨터의 전원이 오프되면, 상기 절전형 멀티콘센트의 멀티콘센트부(15)에 연결된 주변장치들로의 전원도 차단되는 것이다.Therefore, when the power of the personal computer is turned off, power to peripheral devices connected to the multi-outlet 15 of the power-saving multi-outlet is also cut off.

도 2는 상술한 절전형 멀티 콘센트의 일실시예를 보이는 상세회로도로서, PC전원코드의 플러그(도시생략)와 결합되는 제1AC소켓(J1), PC본체의 전원소켓과 결합되는 AC플러그(J2), PC의 주변장치의 전원플러그가 결합되는 제2AC소켓(J3)을 병렬로 연결하고, 상기 제1AC소켓(J1)과 AC플러그(J2)의 사이에 전류센서(J4)를 설치하고, 상기 전류센서(J4)의 출력단을 정류브릿지회로(U2)의 입력단에 연결하고, 상기 정류브릿지회로(U2)의 출력단에는 정류콘덴서(C1) 및 포토커플러(U1)의 발광부를 병렬로 연결하고, 상기 포토커플러(U1)의 발광부에는 전류제한용 저항(R1)을 직렬로 연결하며, 상기 포토커플러(U1)의 수광부는 스위칭동작하는 트라이액(Q1)의게이트에 전압을 인가하도록 연결하고, 상기 트라이액(Q1)은 상기 제2AC소켓(J3)과 연결에 직렬로 연결하여 구성한다.Figure 2 is a detailed circuit diagram showing an embodiment of the power-saving multi-outlet described above, the first AC socket (J1) coupled with the plug (not shown) of the PC power cord, AC plug (J2) coupled with the power socket of the PC body The second AC socket J3 coupled to the power plug of the peripheral device of the PC is connected in parallel, and the current sensor J4 is installed between the first AC socket J1 and the AC plug J2, and the current The output terminal of the sensor J4 is connected to the input terminal of the rectifying bridge circuit U2, and the light emitting part of the rectifying capacitor C1 and the photo coupler U1 is connected in parallel to the output terminal of the rectifying bridge circuit U2, and the photo is connected. A current limiting resistor R1 is connected in series to the light emitting unit of the coupler U1, and the light receiving unit of the photocoupler U1 is connected to apply a voltage to a gate of the triac Q1 that operates switching. Liquid Q1 is configured by connecting in series with the second AC socket J3.

즉, 상기와 같은 회로는 전원이 제1AC소켓(J1)과 AC플러그(J2)를 통해 퍼스널 컴퓨터로 인가되는 경우, 그에 따라 발생된 전류가 전류센서(J4)에 검출되어 정류브릿지회로(U2)로 인가되고, 상기 검출전류는 소정의 전압으로 변환되어 출력된다. 상기 정류브릿지회로(U2)로부터 출력된 전압은 포토커플러(U1)의 발광부에 인가되어 발광부를 동작시키고, 이에 수광부에 전류가 발생하여 트라이액(Q1)의 게이트에 소정 전류를 인가한다. 그 결과 트라이액(Q1)이 턴 온 동작하여 상기 제2AC소켓(J3)을 상기 제1AC소켓(J1)에 연결시킨다.That is, in the circuit as described above, when power is applied to the personal computer through the first AC socket J1 and the AC plug J2, the generated current is detected by the current sensor J4 and the rectifying bridge circuit U2 is applied. The detection current is converted into a predetermined voltage and output. The voltage output from the rectifying bridge circuit U2 is applied to the light emitting portion of the photocoupler U1 to operate the light emitting portion, and a current is generated in the light receiving portion to apply a predetermined current to the gate of the triac Q1. As a result, the triac Q1 is turned on to connect the second AC socket J3 to the first AC socket J1.

그리고, 상기 AC플러그(J2)와 결합된 PC본체에서 전원차단에 의해서 제1AC소켓(J1)과 AC플러그(J2)사이에 흐르는 전류 값이 소정 레벨이하로 떨어지면, 정류브릿지회로(U2)의 출력단으로 출력되는 전압레벨도 그에 비례하여 떨어진다. 이렇게 상기 전압레벨이 발광부의 동작전압이하로 떨어지면, 즉 거의 0이 되면 포토커플러(U1)가 동작하지 않고, 그에 따라 트라이액(Q1)이 턴 오프되어, 제2AC소켓(J3)으로 전원이 인가되지 못하게 한다.When the value of the current flowing between the first AC socket J1 and the AC plug J2 falls below a predetermined level in the PC main body coupled with the AC plug J2, the output terminal of the rectifying bridge circuit U2 is lowered. The voltage level output by the controller drops in proportion to it. When the voltage level falls below the operating voltage of the light emitting unit, i.e., almost zero, the photocoupler U1 does not operate. Accordingly, the triac Q1 is turned off to supply power to the second AC socket J3. Do not let it.

상술한 바와 같이 동작하도록 구성된 절전형 멀티 콘센트는 도 3에 도시한 바와 같이, 정면(31)에 주변장치의 전원플러그와 결합되는 다수의 AC소켓부(31a)와 PC의 전원플러그와 결합되는 PC전원소켓부(31b)가 형성되고, 그 후면(33)에는 상기 PC전원소켓부와 연결되며 PC본체에 설치된 전원소켓에 결합되는 PC전원플러그부(33a)가 구비되는 형태로 구현되며, 이와 같이 구현된 절전형 멀티콘센트는 실제 PC본체에 도 4에 도시한 바와 같이 장착될 수 있다.As shown in FIG. 3, the power-saving multi-outlet configured to operate as described above includes a plurality of AC socket portions 31a coupled to a power plug of a peripheral device and a PC power source coupled to a power plug of a PC, as shown in FIG. 3. The socket portion 31b is formed, and the rear surface 33 is implemented in a form in which the PC power plug portion 33a is connected to the PC power socket portion and coupled to the power socket installed on the PC body. The power saving multi-outlet can be mounted on the actual PC main body as shown in FIG. 4.
