본 고안은 콘센트에 있어서 특히 평상시에는 전원이 차단상태로 되어 있다가 스위치를 눌러 프로그래머블타이머에 신호를 가해주므로서 일정한 주파수발진을 받아들여 카운터하기 시작하여 트랜지스터를 동작하여 릴레이를 구동시킨 후 출력전압을 오프시켜 릴레이구동을 멈추게하여 정해진 시간만큼 부하측에 전원을 공급할 수 있게한 시간제어회로 내장형 콘센트에 관한 것이다.The present invention, especially in the power outlet, the power supply is cut off, and presses a switch to give a programmable timer a signal to accept a constant frequency oscillation, start to count, operate the transistor to drive the relay and then output the voltage The present invention relates to an outlet having a built-in time control circuit which stops the relay driving to supply power to the load by a predetermined time.

종래의 일반적인 콘센트는 접점부위까지 전류가 흐르게 되어 있어 어린이들이 금속성막대나 장난감등을 콘센트에 끼웠을 경우에 전류가 흘러 감전사고등의 위험이 뒤따랐으며, 또한 전기기구를 콘센트에 끼워서 사용하고 난후 콘센트에서 코드를 분리하지 않고 기기자체 스위치만 오프(OFF)시키게 되면 기기내부에 미소전류가 항상 흘러 부품의 내구성이 결여되고 제품의 수명단축 내지는 파손등의 염려가 있고 잔여전류가 흘러 전력소모가 증가할 뿐만 아니라 기기의 과열로 인한 화재의 위험성을 안고 있었던 것이다.Conventional outlets have a current that flows to the contacts, so when children insert metal rods or toys into the outlets, electric current flows, and there is a risk of electric shock. If only the device's own switch is turned off without disconnecting the cord, the micro-current always flows inside the device, resulting in lack of durability of the parts, shortening of the product's lifespan or damage, and increase of power consumption due to residual current. In addition, there was a risk of fire due to overheating of the device.

또한 본인의 선출원 등록된(실용신안공고89-9127)제어회로가 내장된 절전형 콘센트는 타이머회로부와 병렬 접속된 릴레이를 이용한 회로를 구성하여 RC상수에 의한 시간결정방식을 사용하였으므로 잡음(NOISE)이 많이 발생되어 이로인해 시간오차가 많고(3-10% 이상) 전원유입상태를 콘센트에서 한쪽극만 오프시키므로서 기기내의 기판에는 언제나 미소전류가 흘러 부품의 내구성이 떨어지고 불필요한 전력소모를 초래하였으므로 보다 신뢰성 있는 절전형 콘센트의 개발이 절실히 요구되었던 것이다.In addition, the power-saving receptacle with a built-in control circuit registered in the previous application (Utility Model Notification 89-9127) has a circuit using a relay connected in parallel with the timer circuit part, so that the time constant method by RC constant is used. Due to the large number of errors caused by this, there is a large time error (more than 3-10%), and by turning off only one pole of the power supply, the micro-circuit always flows to the board in the device, resulting in poor durability and unnecessary power consumption. Development of power-saving outlets was urgently needed.

따라서 본 고안에서는 상기와 같은 제반 결점을 해소하기 위하여 안출된 것으로서 그 목적으로는 프로그래머블타이머에 의한 주파수카운터방식을 이용하여 두개의 릴레이로 출력단을 제어하여 2선(+, -)을 모두 오프시켜줌으로 출력단에 AC전류가 흐르지 않게 하고 스위치를 거쳐 인가된 전원에 의해 프로그래머블타이머가 구동되어 트랜지스터와 릴레이를 작동시켜 전원을 부하에 공급하지만 상기 프로그래머블타이머에 정해진 시간이 흐른뒤 릴레이를 프시켜서 출력단을 제어함과 동시에 프로그램머블타이머에 공급되는 전원도 차단하여 오차를 (1%이하)을 줄이며 부품의 내구성을 증가시키고 전력소모를 줄일 수 있는 회로를 제공하는데 있다.Therefore, the present invention was devised to solve the above-mentioned shortcomings, and for this purpose, by controlling the output terminal with two relays using the frequency counter method by a programmable timer, the two wires (+,-) are turned off. Programmable timer is driven by the power applied through the switch to prevent the AC current from flowing through the output stage. The transistor and the relay are operated to supply power to the load, but after the predetermined time has passed to the programmable timer, the relay is controlled by controlling the output stage. At the same time, it cuts off the power supplied to the programmable timer to reduce the error (less than 1%), increase the durability of the component and reduce the power consumption.

이를 첨부된 도면에 의해 설명하기로 한다. 전원(AC)을 인가하는데 있어 스위치(SW)와 병렬접속된 저항(R1)과 콘덴서(C1)를 브릿지다이오드(BD)에 각각 연결하고, 브릿지다이오드(BD)를 콘덴서(C2)와 저항(R2)과 제너다이오드(ZD)를 통해 프로그래머블타이머(10)에 접속하고 브릿지다이오드(BD)를 다이오드(D2)(D1)를 거쳐 트랜지스터(TR) 콜렉터 및 릴레이(RY2)(RY1)를 통해 부하(20)와 연결되게 하며 상기 프로그래머블타이머(10)에 가변저항(VR)과 콘덴서(C3)와 저항(R3)를 접속하고 프로그래머블타이머(10)를 저항(R4)을 경유하여 트랜지스터(TR)베이스에 연결하여서된 시간제어회로 내장형 콘센트인 것이다.This will be described with reference to the accompanying drawings. In applying the power source AC, a resistor R 1 and a capacitor C 1 connected in parallel with the switch SW are connected to the bridge diode BD, and the bridge diode BD is connected to the capacitor C 2 . The resistor (R 2 ) and the Zener diode (ZD) are connected to the programmable timer 10 and the bridge diode (BD) is connected to the transistor (TR) collector and relay (RY 2 ) (through diode (D 2 ) (D 1 ) ( RY 1 to be connected to the load 20 and the variable timer (VR), the capacitor (C 3 ) and the resistor (R 3 ) is connected to the programmable timer (10) and the programmable timer (10) is a resistor (R 4) It is a socket with built-in time control circuit connected to transistor (TR) base via)

이하 첨부된 도면에 본 고안의 작용 및 효과를 설명한다. 전원(AC)를 인가한후 사용자가 스위치(SW)를 누르면 병렬접속된 저항(R1)과 콘덴서(C1)를 경유하여 전압을 다운시킨후 브릿지다이오드(BD)와 콘덴서(C2)에 의해 릴레이(RY1)(RY2) 구동전압(Vccc1)이 만들어지고 다시 릴레이(RY1)(RY2) 구동전압(Vcc1)을 저항(R2)과 제너다이오드(ZD)에 의해 프로그래머블타이머(10) 구동전압(Vcc)이 만들어진다.Hereinafter, the operation and effects of the present invention will be described in the accompanying drawings. When the user presses the switch (SW) after applying the power (AC), the voltage is lowered via the resistor (R 1 ) and the capacitor (C 1 ) connected in parallel to the bridge diode (BD) and the capacitor (C 2 ). The relay (RY 1 ) (RY 2 ) drive voltage (Vccc 1 ) is created and the relay (RY 1 ) (RY 2 ) drive voltage (Vcc 1 ) is programmable by the resistor (R 2 ) and zener diode (ZD). The timer 10 driving voltage Vcc is made.

따라서 상기 프로그래머블타이머(10)는 전원(AC)이 인가되면 가변저항(VR)과 콘덴서(C3)와 저항(R3)에 의해 정해진 일정 주파수를 발생시키는 한편 발생된 주파수를 카운터하기 시작하며 동시에 출력전압이 저항(R4)을 경유하여 트랜지스터(TR) 베이스에 인가되어 상기 트랜지스터(TR)를 도통시켜 릴레이(RY1)(RY2)가 구동되므로 부하(20)에 전원(AC)이 공급되는 것이다.Therefore, when the power supply AC is applied, the programmable timer 10 generates a predetermined frequency defined by the variable resistor VR, the capacitor C 3 , and the resistor R 3 , and starts to count the generated frequency. The output voltage is applied to the transistor TR base via the resistor R 4 to conduct the transistor TR so that the relay RY 1 and RY 2 are driven to supply the power AC to the load 20. Will be.

이때 프로그래머블타이머(10)는 가변저항(VR)과 콘덴서(C3)와 저항(R3)에 의해 일정시간 동안 정해진 주파수만큼 카운터한후 출력전압을 오프(OFF)시켜 트랜지스터(TR) 베이스에 전압을 인가하지 못하게 되므로 릴레이(RY1)(RY2)가 구동되지 않아 부하(20)에 전원(AC)을 공급하지 못하게 된다.At this time, the programmable timer 10 counters the predetermined frequency for a predetermined time by the variable resistor VR, the capacitor C 3 , and the resistor R 3 , and then turns off the output voltage to turn off the voltage at the base of the transistor TR. Since the relay is not applied, the relay RY 1 and RY 2 are not driven, thereby preventing the power supply AC from being supplied to the load 20.

또한 평상시에는 콘센트 양극(+, -)에 전원이 공급되지 않지만 반드시 사용자가 스위치(SW)를 누름과 동시에 프로그래머블타이머(10)와 릴레이(RY1)(RY2)가 구동되어야만 전원(AC)이 부하(20)에 공급되므로 평소 소비되는 전력이 없다.In addition, power is not supplied to the positive pole (+,-) at normal times, but the user must press the switch (SW) and the programmable timer (10) and the relay (RY 1 ) (RY 2 ) must be driven to supply power (AC). Since it is supplied to the load 20, there is no power normally consumed.

상술한 바와 같이 본 고안을 전기기기등을 사용하지 않을때 전원(AC)이 공급되는 콘센트의 양극(+, -)을 모두 오프(OFF)시키므로 사용자가 기기를 사용하고 난후 콘센트에서 코드를 분리하지 않고 자체스위치만 오프시켜도 기기내의 부품에 전류가 흐르지 않게 되어 불필요한 전력소모를 줄이고 부품의 내구성을 향상시킬 수 있으며 유아 또는 어린이들의 감전사고를 미연에 방지할 수 있는 유익한 고안이다.As described above, when the electric device is not used, the present invention turns off both the positive and negative poles of the outlet to which the power is supplied. It is an advantageous design to prevent unnecessary electric power consumption, improve the durability of parts, and prevent electric shocks of infants or children, even if only the switch is turned off and no current flows to the parts in the device.
