Description

솔레노이드(SOLENOID)의 전압인가장치Solenoid voltage application device

제1도는 본 고안의 회로도.1 is a circuit diagram of the present invention.

제2도는 종래의 솔레노이드의 전압인가장치 회로도.2 is a circuit diagram of a voltage applying device of a conventional solenoid.

본 고안은 카세트테크의 기계적 조작이 아닌 소프트터치(SOFT TOUCH)식 데크에서 사용되는 솔레노이드의 동작을 안정되고 신뢰성있게 향상시킬 수 있는 장치에 관한 것이다.The present invention relates to a device that can stably and reliably improve the operation of solenoids used in soft touch (SOFT TOUCH) decks, rather than mechanical operations of cassette tech.

통상적으로는 제2도(b)와 같이, 스위치(SW)를 단락시키거나, (a)와 같이 트랜지스터(Tr)를 동작시켜 솔레노이드(L)에 전원전압(+B)이 그대로 인가되도록 하였는데, 이러한 방법은 솔레노이드가 일종의 인덕턴스(INDUCTANCE)이므로 전압이 걸리는 초기에는 임피던스(IMPEDANCE)가 거의 무한대에 가깝게 커지고, 정상상태시에는 임피던스가 거의 "0"에 가까와지므로, 솔레노이드를 통하여 상당량의 전류가 계속 흘러서 솔레노이드에 열이 발생하게 되어서 솔레노이드의 수명을 단축시키게 되며, 또한 솔레노이드에 이상적으로 전압을 인가하려면 초기에는 큰 전압이 걸리게 하고, 정상상태에서는 작은 전압이 걸리게 하여야 하는데, 이러기 위해서 종래에는 저항(R)을 삽입하여 주었으나 저항(R) 값이 너무 크면 초기에 솔레노이드에 걸리는 전압이 작아지고, 저항(R)값이 너무 작으면 정상상태에서 전류가 많이 흘러 효과가 없게 되어, 저항값(R)을 결정하기가 까다로운등의 많은 문제점이 있었다.Typically, as shown in FIG. 2 (b), the switch SW is shorted or the transistor Tr is operated as shown in (a) so that the power supply voltage ( + B) is applied to the solenoid L as it is. In this method, since the solenoid is a kind of inductance, the impedance becomes almost infinity at the beginning of the voltage, and the impedance approaches almost "0" in the steady state, so that a large amount of current continues to flow through the solenoid. Heat is generated in the solenoid, which shortens the life of the solenoid. Also, in order to apply an ideal voltage to the solenoid, a large voltage is initially required and a small voltage is normally applied in a normal state. If the resistance (R) value is too large, the voltage applied to the solenoid initially becomes small, and the resistance (R) value If too small, a large amount of current flows in a steady state, thereby ineffective, and it is difficult to determine the resistance value (R).

따라서, 본 고안은 이러한 결점을 해소하고자 안출한 것으로, 이를 첨부된 도면에 따라 상세히 설명하면 다음과 같다.Therefore, the present invention has been devised to solve such a drawback, which will be described in detail with reference to the accompanying drawings.

제1도와 같이, 통상의 다이오드와 솔레노이드(L)로 이뤄진 솔레노이드 전압인가회로에 있어서, 트랜지스터(Q1)의 콜렉터측은 저항(R1)을 거쳐 트랜지스터(Q2)의 콜렉터측과 솔레노이드(L)의 일측사이에 연결하고, 트랜지스터(Q1),(Q2)의 에미터측을 서로 연결하여 접지점(G)과 연결하며, 트랜지스터(Q1)의 베이스측은 저항(R2)을 거쳐 입력단자(I)와 다이오드(D1)의 애노드측에 연결하고, 캐소드 측은 저항(R3)을 거쳐 접지점(G) 및 콘덴서(C)에 연결하며, 콘덴서(C)일측은 다이오드(D2), 저항(R4), 트랜지스터(Q2)의 베이스측 사이에 연결하고, 다이오드(D2), 저항(R4)일측은 접지점(G)에 연결시켜서 된 것이다.First as help, the conventional diode and the solenoid (L) according to the solenoid voltage application circuit, the collector side and the solenoid of the side of the collector of the transistor (Q 1) resistance (R 1) a transistor (Q 2) through (L) yirwojin in The emitters of transistors Q 1 and Q 2 are connected to each other to the ground point G, and the base side of transistor Q 1 is connected to the input terminal via a resistor R 2 . I) and the anode side of the diode (D 1 ), the cathode side is connected to the ground point (G) and the capacitor (C) via a resistor (R 3 ), one side of the capacitor (C) is a diode (D 2 ), a resistor It is connected between (R 4 ) and the base side of transistor Q 2 , and one side of diode (D 2 ) and resistor (R 4 ) is connected to ground point (G).

이와 같은 구성의 본 고안은 스위치(SW)를 닫는 순간 입력단자(I)을 통한 입력신호가 "O"에서 "V"로 상승하면 다이오드(D1)를 통하여 연결된 콘덴서(C)가 초기시에 단락상태가 되므로, 이 콘덴서(C)를 통하여 전류가 흐르게 된다. 따라서 트랜지스터(Q2)는 "ON" 상태가 되어 A점이 접지(G)점의 전위로 떨어지고, 솔레노이드(L)에는 전원전압(+B)이 전부 인가된다.By this the design of such configuration is to close a switch (SW) the moment the input signal through the input terminal (I) is raised from "O" to "V" the capacitor (C) connected via a diode (D 1) in the initial Since a short circuit occurs, current flows through the capacitor C. Therefore, the transistor Q 2 is turned "ON", the point A falls to the potential of the ground (G) point, and the power supply voltage ( + B) is applied to the solenoid L entirely.

다음 정상상태에 다달으면 콘덴서(C)는 만충전으로 개방되어 버리므로 트랜지스터(Q2)는 "OFF" 된다.When the next steady state is reached, the capacitor C is opened at full charge, so the transistor Q 2 is turned off.

이때 트랜지스터(Q1)의 베이스에는 계속 전류가 흐르고 있으므로 트랜지스터(Q1)는 "ON" 상태로 남아 있으며 A점은 저항(R1)을 통하여 접지된다.At this time, since the transistor base is still current in the (Q 1) flows through the transistor (Q 1) is left in the "ON" state, and the point A is grounded through a resistor (R 1).

그러므로 솔레노이드(L)에는 저항(R1)에 의하여 분할된 전압이 걸리고 흐르는 전류도 작아져 솔레노이드(L) 동작을 유지할 수 있는 전압이 걸리면서도 열의 발생을 방지할 수 있으며, 다음 신호 전압이 "O"로 떨어졌을때 콘덴서(C)에 충전되어 있던 전하가 방전하지 못하도록 다이오드(D1)가 콘덴서(C)와 직렬로 연결되어 있다.Therefore, the solenoid L takes the voltage divided by the resistor R 1 and the current flowing also becomes small to prevent the generation of heat while taking the voltage that can maintain the solenoid L operation. The diode D 1 is connected in series with the capacitor C to prevent the charge charged in the capacitor C from discharging when it drops to "

이상과 같은 본 고안은 솔레노이드를 구동시킬때 처음 구동시 충분한 전압을 솔레노이드에 걸어서, 구동시킨 후 정상상태에서 솔레노이드에 걸리는 전압을 떨어뜨리는, 즉 초기시점과 정상상태에서 솔레노이드에 걸리는 전압이 동일전원이면서도 각기 다른 전압이 걸리도록 하여 솔레노이드 동작시 과열방지와 솔레노이드의 수명을 연장시킴은 물론 안전성과 신뢰성이 향상될 수 있는 실용적인 것이다.The present invention as described above, when driving the solenoid, the first voltage is applied to the solenoid at the time of driving, and after driving it drops the voltage applied to the solenoid in the normal state, that is, the voltage applied to the solenoid at the initial time and the normal state, By applying different voltages, it is practical to prevent overheating and extend the life of solenoid during solenoid operation, and to improve safety and reliability.
