본 고안은 푸쉬버튼 스위치에 관한 것으로, 특히 고무 버튼을 누를때 고무 버튼이 편측으로 기울어져 발생되는 스틱(Stick) 현상을 방지하도록 한 푸쉬버튼 스위치의 스틱 방지장치에 관한 것이다.The present invention relates to a pushbutton switch, and more particularly, to a stick prevention device of a pushbutton switch to prevent a stick phenomenon caused by tilting the rubber button to one side when the rubber button is pressed.
종래의 푸쉬버튼 스위치는 제1(a)도, 제1(b)도에 도시한 바와같이, 고무버튼(1)이 탄성리브(2)(2')에 의해 지지되고, 고무 버튼(1)이 하면에는 고무 전도체(3)가 부착되어 있으며, 인쇄회로기판(5)에는 상기 고무 전도체(3)와 접촉되는 전도체(4)가 부착되어 있다.In the conventional pushbutton switch, as shown in FIG. 1 (a) and FIG. 1 (b), the rubber button 1 is supported by the elastic ribs 2 and 2 ', and the rubber button 1 The rubber conductor 3 is attached to this lower surface, and the conductor 4 in contact with the rubber conductor 3 is attached to the printed circuit board 5.
이러한, 푸쉬버튼 스위치는 고무 버튼(1)을 a방향에서 누를때는 탄성리브(2)(2')에 똑같은 힘이 가해져서 인쇄회로기판(5)의 전도체(4)에 고무 전도체(3)가 접촉되고, b방향에서 누를 때는 탄성리브(2)에서 먼저, c방향에서 누를때는 탄성리브(2')에서 먼저 변형이 일어나서 누른쪽의 고무 전도체(3) 모서리(3')(3")가 먼저 인쇄회로기판(5)의 전도체(4)에 접촉된다.In this pushbutton switch, when the rubber button 1 is pressed in the a direction, the same force is applied to the elastic ribs 2 and 2 'so that the rubber conductor 3 is applied to the conductor 4 of the printed circuit board 5. When pressed in the b direction, deformation occurs first in the elastic rib 2, and when pressed in the c direction, in the elastic rib 2 ', the edges 3' and 3 'of the pressed rubber conductor 3 First, it is in contact with the conductor 4 of the printed circuit board (5).
도면에서 6은 지지 고무를 보인 것이다.6 shows the supporting rubber.
종래 다른 실시형태의 푸쉬버튼 스위치는 제2(a)도, 제2(b)도에 도시한 바와같이, 고무 버튼(8)의 하면의 고무 전도체(3) 주위에 도트(7)(7')가 형성되어 있으며, 그외 구성은 제1도와 동일하게 되어 있다.The pushbutton switch of another conventional embodiment has a dot (7) (7 ') around the rubber conductor (3) of the lower surface of the rubber button (8) as shown in Figs. 2 (a) and 2 (b). ) Is formed, and other configurations are the same as those in FIG.
이러한 다른 실시형태의 푸쉬버튼 스위치는 고무 버튼(8)을 a방향에서 누를 때는 탄성리브(2)(2')에 똑 같은 힘이 가해져서 인쇄회로기판(5)의 전도체(4)에 고무 전도체(3)가 접촉되고, b방향에서 누를때는 탄성리브(2)에서 먼저 탄성 변형이 일어나 도트(7')가 먼저 인쇄회로기판(5)면에 도달되어 더 이상 이동이 일어나지 않기 때문에 반대측 탄성리브(2)의 변형이 일어나 고무 버튼(8)의 고무 전도체(3)가 인쇄회로기판(5)의 전도체(4)에 접촉되어 리모콘의 작동이 일어난다.The pushbutton switch of this other embodiment applies the same force to the elastic ribs 2, 2 'when the rubber button 8 is pressed in the a direction so that the rubber conductors on the conductors 4 of the printed circuit board 5 When (3) is contacted and pressed in the b direction, elastic deformation occurs first in the elastic rib 2 so that the dot 7 'first reaches the surface of the printed circuit board 5 and no further movement occurs. Deformation of (2) occurs so that the rubber conductor 3 of the rubber button 8 contacts the conductor 4 of the printed circuit board 5 so that the operation of the remote controller occurs.
상기한 바와같은 푸쉬버튼 스위치는 도트(7)(7')가 없을때는 경사 작동이 일어나 고무 버튼 스틱이 발생하면 다른 고무 버튼의 작동은 회로적으로 쇼트되어 작동이 일어나지 않게 되므로 사용이 불편한 결함이 있었으며, 또한 도트 (7)(7')를 구비한 것은 도트(7)(7') 구성시 고무의 탄성 수측 특성 때문에 경사 작동 현상은 감소하나 사용자가 a방향 이외에 b, c 방향으로 무리하게 누르면 도트(7)(7')가 수축되면서 편측 경사(기울어짐)현상으로 스틱이 일어나게 되어 사용이 역시 불편한 것이었다.The push button switch as described above is inclined operation when there is no dot (7) (7 '), when the rubber button stick is generated, the operation of the other rubber button is short circuited so that the operation does not occur, there is a defect that is inconvenient to use In addition, the dot 7 (7 ') is provided with a dot (7) (7') in the inclined operating phenomenon is reduced due to the elastic water-side characteristics of the rubber when the user is configured to press the force in the b, c direction other than the a direction As the dots 7 and 7 'contracted, sticks occurred due to unilateral inclination, which was also inconvenient to use.
본 고안은 상기한 바와같은 종래의 결함을 해소하기 위하여, 고무버튼을 누를 때 고무 버튼이 편측으로 기울어져 발생되는 스틱 현상을 방지하도록 안출한 것으로, 이하 이러한 본 고안을 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is designed to prevent the stick phenomenon caused by tilting the rubber button to one side when pressing the rubber button in order to solve the conventional defect as described above, it will be described in detail by the accompanying drawings of the present invention Is as follows.
제3도에 도시한 바와같이, 고무 버튼(9)이 탄성리브(2)(2')에 의해 지지되고, 인쇄회로기판(5)에는 전도체(4)가 부착되어 있으며, 고무 버튼(9)의 하면에는 고무 전도체(3)가 부착되고, 고무 전도체(3)를 주위를 감싸는 형상으로 지지리브(10)(10')가 형성되어 있다.As shown in FIG. 3, the rubber button 9 is supported by the elastic ribs 2, 2 ', and the conductor 4 is attached to the printed circuit board 5, and the rubber button 9 The rubber conductor 3 is attached to the lower surface of the bottom surface, and the support ribs 10 and 10 'are formed in a shape surrounding the rubber conductor 3.
이와같이된 본 고안에 의한 푸쉬버튼 스위치의 고무 버튼(9)을 a 방향으로 누를 때는 인쇄회로기판(5)에 구성된 전도체(4)에 고무 버튼(9)의 고무전도체(3)가 수직으로 이동되어 리모콘의 작동이 일어나게 되고, b방향에서 누를 때는 b방향 쪽에 형성된 지지리브(10')가 작동되어 지지리브(10')가 인쇄회로기판(5)면에 접촉됨과 동시에 고무 전도체(3)가 인쇄회로기판(5)의 전도체(4)에 접촉되어서 작동이 일어나게 된다.When the rubber button 9 of the push button switch according to the present invention is pressed in the a direction, the rubber conductor 3 of the rubber button 9 is moved vertically to the conductor 4 formed on the printed circuit board 5. The operation of the remote controller occurs, and when pressed in the b direction, the support ribs 10 'formed at the b direction are activated so that the support ribs 10' are brought into contact with the printed circuit board 5 surface and the rubber conductor 3 is printed. The operation occurs by contacting the conductor 4 of the circuit board 5.
이때 기울어짐 량은 제2도의 도트(7)(7')의 량과 동일하나 고무 버튼(9)의 하면에 형성된 원형 또는 타원형의 지지리브(10)(10') 때문에 고무 버튼(9)을 무리하게 누를 때 탄성리브(2)(2')의 변형이 작아서 경사작동으로 인한 스틱 현상이 발생하지 않게 된다.At this time, the amount of inclination is the same as the amount of dots 7 and 7 'of FIG. 2, but the rubber button 9 is formed due to the circular or elliptical support ribs 10 and 10' formed on the lower surface of the rubber button 9. When pressing excessively, the deformation of the elastic ribs 2 and 2 'is small so that the sticking phenomenon due to the inclined operation does not occur.
이상에서 설명한 바와 같은 본 고안은 고무 버튼의 하면에 고무 버튼의 형상과 일치된 지지리브를 형성하여 사용자가 작동시 고무 버튼에 무리한 힘을 가하도라도 경사 작동으로 인한 스틱 현상을 방지하도록 되어 있으므로 사용이 편리하고, 이에 따라 제품의 신뢰성을 향상하는 이점이 있다.The present invention as described above is used to prevent the stick phenomenon due to the inclined operation even if the user applies excessive force to the rubber button by forming a support rib matching the shape of the rubber button on the lower surface of the rubber button This is convenient and thus has the advantage of improving the reliability of the product.
