본 고안은 전자기기의 스위치에 관한 것으로, 특히 개량된 터치식 키보드 스위치에 관한 것이다.The present invention relates to a switch of an electronic device, and more particularly to an improved touch keyboard switch.
종래의 일반적인 터치식 키보드 스위치는 제3(b)도에 도시된 바와 같이 회로기판(14)에 전기 접속단자(13)를 설치하고, 단자설치 부위만을 제외한 나머지 부분의 회로기판(14)에 절연체(16)를 피복시킨 다음 맞은편의 접속단자(11)를 유연성이 있는 누름판(12)에 설치해 놓은 구조로 되어 있었다.In the conventional general touch keyboard switch, as shown in FIG. 3 (b), the electrical connection terminal 13 is installed on the circuit board 14, and the insulator is provided on the circuit board 14 of the remaining portions except for the terminal installation portion. (16) was coated, and the opposite connecting terminal 11 was provided on the flexible pressing plate 12. As shown in FIG.
이와 같은 종래의 터치식 키보드 스위치는 외부에서 일정한 외력을 가해야만 제3(b)도에서 처럼 양쪽 단자가 서로 접속되어 통상의 원칩마이콤에서 감지할 수 있도록 된 터치식 키보드 스위치를 제공함에 그 목적이 있다.Such a conventional touch keyboard switch is to provide a touch keyboard switch that both terminals are connected to each other and can be detected by a conventional one-chip microcomb as shown in FIG. 3 (b) only when external force is applied externally. have.
이와 같은 목적을 달성하기 위해 본 고안의 터치식 키보드 스위치는 회로기판과 누름판 사이에 접속단자와 접하도록 유리판을 설치하여 사람의 손가락과 유리판을 사이에 둔 접속단자 사이의 전류흐름을 첵크하여 누름판에 일정한 의력을 가하지 않고 손가락으로 상기 누름판에 접촉만 하여도 스위치를 ON-OFF 시킬 수 있는 구조로 되어 있다.In order to achieve the above object, the touch keyboard switch of the present invention installs a glass plate so as to contact the connection terminal between the circuit board and the pressing plate, and checks the current flow between the connection terminal between the human finger and the glass plate to the pressing plate. The switch can be turned on and off only by touching the pressing plate with a finger without applying a constant force.
이하, 본 고안을 첨부된 예시 도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 ""자형의 단자(1)가 장착된 누름판(2)과 ""형 접속단자(3)가 설치된 회로기판(4) 사이에 절연체인 유리판(5)을 부착시키되, 상기 유리판(5)의 전면부에 설치되는 단자(1)는 산화주석 또는 백금으로 코팅 처리하고, 후면부에 설치되는 단자(3)는 은 또는 탄소가 코팅 처리되어 있는 구조로 되어 있다.This design is " "Pressure plate (2) with shaped terminal (1) and" A glass plate 5, which is an insulator, is attached between the circuit boards 4 on which the “type connection terminals 3” are installed, and the terminal 1 installed on the front surface of the glass plate 5 is coated with tin oxide or platinum. The terminal 3 provided on the rear portion has a structure in which silver or carbon is coated.
이상과 같이 구성된 본 고안은 제1도 및 제2도에 도시된 바와 같이 도체인 회로기판(4)과 절연체인 누름판(2) 사이에 유리판(5)이 설치되면서, 이 유리판(5) 전면부에 ""자형의 단자(1)가 접하고, 후면부에는 ""형 접속단자(3)가 접하도록 되어 있다.The present invention constructed as described above has the glass plate 5 between the circuit board 4, which is a conductor, and the pressing plate 2, which is an insulator, as shown in FIGS. On " "Shaped terminal (1) is in contact, the rear part is" "Type connection terminal 3 is in contact.
상기 유리판(5)의 전면부에 접한 ""자형 단자(1)의 재질은 주로 산화주식 혹은 백금으로 코팅 처리되고 상기 유리판(5) 뒷면부에 접하는 ""형 접속단자(3)는 은 혹은 탄소로 코팅된다.Contacting the front part of the glass plate 5 " "The material of the female terminal 1 is mainly coated with oxide stock or platinum and is in contact with the rear portion of the glass plate (5)" "Type connection terminal 3 is coated with silver or carbon.
일반적으로 유리판(5)의 전·후면부에 전극인 단자(1)가 부착되어 있으면 유리판(5)은 절연체로서 하나의 캐퍼시터를 형성하게 되므로 본 고안에 따른 스위치에 손가락을 접촉하게 되면 제3(a)도에 도시된 화살표 방향으로 전류가 흐르게 되는 바, 이때 도면에 표시된 바와 같이 사람도 하나의 캐퍼시터 역할을 하여 전류가 몸체에 흐르게 된다.In general, when the terminal 1, which is an electrode, is attached to the front and rear surfaces of the glass plate 5, the glass plate 5 forms one capacitor as an insulator. The current flows in the direction of the arrow shown in Figure 6), and as shown in the figure, a person also acts as a capacitor so that the current flows through the body.
그러면, 제3(a)도의 등가회로도인 제6도에 도시된 바와 같이 유리판(5)의 양극 사이에 형성된 캐퍼시터(C1)(C2) 사이에 손가락을 접촉하게 되면, 또 하나의 캐퍼시터(C3)가 형성되게 되는 바, 여기서 상기 캐퍼시터(C3)는 사람의 신체가 하나의 캐퍼시터가 되어 사람의 몸으로 전류의 일부가 흐르게 되고, 또한 펄스발생기(PG)에서 송출된 -Vss 전위차를 가진 펄스가 공통전극인 ""형 접속단자(3)에 공급되고 있으며, 또 다른 캐퍼시터(C4)는 회로기판(4)의 포유 캐퍼시터로서 역할을 하게 된다.Then, as shown in FIG. 6, which is an equivalent circuit diagram of FIG. 3 (a), when a finger touches between the capacitors C 1 and C 2 formed between the anodes of the glass plate 5, another capacitor ( C 3 ) is formed, wherein the capacitor (C 3 ) is a capacitor of the human body is a part of the current flows to the human body, and also the -Vss potential difference transmitted from the pulse generator (PG) Excitation pulse is the common electrode " "Which is supplied to form the connection terminal (3), another capacitor (C 4) is to act as a mammal capacitor of the circuit board 4.
이에 따라 먼저 본 고안에 사람의 손가락이 접촉되게 되면 사람의 신체가 하나의 캐퍼시터(C3) 역할을 하게 되어 전류의 일부가 몸체로 흐르게 되므로 제5(a)도와 같이 전위차가 감소되게 되고, 그에 따라 기준전압(Vref) 보다 낮은 제5(a)도에 도시된 전압(Vpp)의 신호가 도면에 도시되지 않은 공지의 원칩마이콤에서 감지되어 스위치의 누름판(2)이 터치되었음을 알게 된다.Accordingly, when a person's finger is first touched by the present invention, the body of the person acts as one capacitor C 3 so that a part of the current flows into the body, thereby reducing the potential difference as shown in FIG. 5 (a). Accordingly, a signal of the voltage Vpp shown in FIG. 5 (a) lower than the reference voltage Vref is detected by a known one-chip microcomputer not shown in the drawing, and it is known that the pressing plate 2 of the switch is touched.
이와 달리 본 고안에 사람의 손가락이 접촉되지 않으면 유리판(5)의 양극 사이에 형성된 캐퍼시터(C1)(C2) 사이에 또 하나의 캐퍼시터(C3)가 형성되지 않아 제5(b)도와 같이 신호가 기준전압(Vref)보다 높은 전압(Vss)의 신호로서 상기 원칩마이콤에 공급되므로 스위치의 누름판(2)이 접촉되지 않았음을 알게 되는 것이다.On the other hand, if the human finger is not in contact with the present invention, another capacitor C 3 is not formed between the capacitors C 1 and C 2 formed between the anodes of the glass plate 5, and thus the fifth (b) diagram is shown. Similarly, since the signal is supplied to the one-chip microcomputer as a signal having a voltage Vss higher than the reference voltage Vref, it is known that the pressing plate 2 of the switch is not in contact.
이와 같이 종래의 터치식 키보드 스위치는 제3(b)도와 같이 탄성체로 제작된 절연체(16)를 설치하여 일정한 외력을 가해야만 작동되었으나, 본 고안은 누름판과 회로기판 사이에 단자와 접속단자가 접하는 유리판을 설치해 놓음으로서 누름판에 외력을 가하지 않고 손가락만 살짝 접촉시켜 주기만 하면 스위치를 ON-OFF시킬 수 있게 되는 것이다.As described above, the conventional touch-type keyboard switch is operated only by applying a constant external force by installing an insulator 16 made of an elastic body as shown in FIG. 3 (b). However, the present invention is in contact with the terminal and the connection terminal between the pressing plate and the circuit board. By installing the glass plate, you can turn the switch on and off simply by touching your finger slightly without applying external force to the pressing plate.
