본 발명은 전자기기의 키버튼에 관한 것으로서, 특히 키버튼들의 부품을 하나로 일체화된 프레임으로 제작하여 조립하기 용이하게한 키버튼에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key button of an electronic device, and more particularly, to a key button which is easy to assemble by fabricating parts of the key buttons into an integrated frame.
종래에는 제1도에 도시한 바와 같이 각각의 키버튼(21)을 제작하기 위하여 금형에서 사출하면 러너(22)의 각각 게이트(23) 끝단에 일체로된 키버튼(21)들이 형성된다.Conventionally, as shown in FIG. 1, when the mold is ejected from the mold in order to manufacture the respective key buttons 21, the key buttons 21 are integrally formed at the ends of the gates 23 of the runners 22, respectively.
상기와 같은 각각의 키버튼(21)을 본체 하우징(24)에 형성된 구멍(25)에 조립하기 위해서 각각의 키버튼(21)을 러너(22)의 게이트(23)에서 분리하여 제2도와 같이 본체하우징(24)의 구멍(25)에 각각 키버튼(21)을 삽입하고 인쇄회로기판(26)에 형성된 접점(27)의 상면에는 도전막(29)과 탄성부를 가지는 접촉고무(28)를 배치한 후 상기 키버튼(21)이 접촉고무(28)의 상면에 위치하도록 조립하여 사용하였다.In order to assemble each key button 21 as described above into the hole 25 formed in the main body housing 24, each key button 21 is separated from the gate 23 of the runner 22, as shown in FIG. The key buttons 21 are respectively inserted into the holes 25 of the main body housing 24, and the contact rubber 28 having the conductive film 29 and the elastic part is formed on the upper surface of the contact 27 formed on the printed circuit board 26. After the arrangement, the key button 21 was assembled to be positioned on the upper surface of the contact rubber 28.
이와같이 구성된 종래의 키버튼 장치는 키버튼(21)을 누르면 이와 접촉하고 있는 접촉고무(28)가 하강하며 저면의 도전막(29)이 인쇄회로기판(26)의 접점(27)을 도통시켜 신호를 출력하게 되는데 이와같은 장치는 각각의 키버튼이 별도로 형성되어 있어 본체하우징(24)에 하나씩 별개로 조립하여야 하므로 조립 능률의 저하를 초래하며 숙련자가 않일경우 키버튼을 오 조립하는 경우가 발생하였다.In the conventional key button device configured as described above, when the key button 21 is pressed, the contact rubber 28 in contact with it is lowered, and the conductive film 29 on the bottom conducts the contact 27 of the printed circuit board 26 to signal. Since such a key button is formed separately, each device must be assembled separately one by one in the main housing (24), resulting in deterioration of the assembly efficiency. .
본 발명은 이와같은 문제점을 해소하기 위하여 안출된 것으로 본 발명의 목적은 각각의 키버튼을 일체로 형성하여 본체하우징에 키버튼을 조립시 다수개가 일체로된 키버튼 전체를 조립하여 조립능률을 향상시킬 수 있으며, 미숙련자도 쉽고 정확하게 조립할 수 있도록 키버튼을 제공함에 있다.The present invention has been made in order to solve the above problems, the object of the present invention is to form the respective key button integrally when assembling the key button assembling the whole of the key housing in the main body housing to improve the assembly efficiency The key button is provided so that even an inexperienced person can assemble easily and accurately.
상기와 같은 목적을 달성하기 위한 본 발명은 버튼 프레임에 다수개의 키버튼을 일체로 형성하되 각각의 키버튼은 탄력있는 텐션리브로 연결됨과 동시에 이탈을 방지하기위해 걸림턱이 형성됨을 특성으로 한다.The present invention for achieving the above object is characterized in that a plurality of key buttons are integrally formed in the button frame, but each key button is connected to an elastic tension rib and at the same time a locking jaw is formed to prevent separation.
상기와 같은 본 발명의 바람직한 실시예를 첨부된 도면에 의거 상세히 설명되어질 것이다.Preferred embodiments of the present invention as described above will be described in detail with reference to the accompanying drawings.
제3,4도를 참조하여 본 발명의 구성을 설명하면, 인쇄회로기판(9)상면에 설치된 접촉고무(10)를 눌러주며 본체하우징(7)에 설치되는 버튼 프레임(1)에 공간부(2)를 이룬 중앙에 위치하도록 다수개의 키버튼(3)을 일체로 형성하되, 상기 각각의 키버튼(3)들은 상면으로 돌출되며, 하단 외측에 이탈을 방지하기 위한 걸림턱(4)과 양단에 탄력있는 텐션리브(5)를 각각 형성한다.Referring to FIGS. 3 and 4, the structure of the present invention is described by pressing the contact rubber 10 installed on the upper surface of the printed circuit board 9 and having a space portion in the button frame 1 installed in the main body housing 7. 2) A plurality of key buttons 3 are integrally formed so as to be positioned at the center, each of the key buttons 3 protruding to the upper surface, and the locking jaw 4 and both ends to prevent the separation from the lower side. Resilient tension ribs 5 are respectively formed on the back side.
상기 텐션리브(5)가 각각 반대축의 버튼 프레임(1)에 일체화되게 형성하고, 상기 버튼 프레임(1)에 오조립 방지를 위해 비대칭으로 고정구멍(6)이 형성된 것이다.The tension ribs 5 are formed integrally with the button frame 1 of the opposite axis, respectively, and the fixing holes 6 are asymmetrically formed in the button frame 1 to prevent misassembly.
상기 텐션리브(5)는 탄성을 가지도록 폭을 1㎜ 두께를 0.7㎜로 하며, 본체하우징(7)에 키버튼(3)이 가로, 세로 방향으로 다수개 형성된 버튼 프레임(1)을 조립할때는 조립성이 더 우수한 것이다.The tension rib 5 has a width of 1 mm and a thickness of 0.7 mm so as to have elasticity, and when assembling the button frame 1 in which a plurality of key buttons 3 are formed in the body housing 7 in the horizontal and vertical directions, The assembly is better.
이와 같이 구성된 본 발명의 작용 및 효과는 다음과 같다.The operation and effects of the present invention configured as described above are as follows.
본체하우징(7)에 형성된 각각의 구멍(8)과 대응되는 위치에 버튼 프레임(1)에 형성된 각각의 키버튼(3)을 삽입한 후 인쇄회로기판(9)상에 설치된 접촉고무(10)에 위치하도록 버튼 프레임(1)을 설치한다.The contact rubber 10 installed on the printed circuit board 9 after inserting each key button 3 formed in the button frame 1 at a position corresponding to each hole 8 formed in the main body housing 7. Install the button frame (1) to be located at.
이때 버튼 프레임(9)에 다수개의 키버튼(3)이 일체로 형성되어 있음므로 하나의 부품 본체하우징(7)에 설치하므로 조립이 완료된다. 그러므로 버튼 프레임(1)을 조립시 자동화 시스템에 적용할 수 있는 것이다.In this case, since a plurality of key buttons 3 are integrally formed in the button frame 9, the assembly is completed since the key frame 3 is installed in one component main body housing 7. Therefore, the button frame 1 can be applied to the automation system when assembling.
상기와 같은 상태에서 본체하우징(7)의 구멍(8)을 통하여 상면으로 돌출된 키버튼(3)을 누르게 되면 키버튼(3)이 하강하면서 접촉고무(10)를 눌러주므로 접촉고무(10) 하면의 도전막(11)이 인쇄회로기판(9)의 접점(12)을 도통시켜 신호를 출력할 수 있게 된다.When the key button 3 protruding to the upper surface through the hole 8 of the main body housing 7 in the above state is pressed, the key button 3 is lowered and the contact rubber 10 is pressed down so that the contact rubber 10 is pressed. The conductive film 11 on the lower surface conducts the contacts 12 of the printed circuit board 9 to output a signal.
이때 키버튼(3)은 상부에서 눌러주므로 하강할때 양단에 반대측으로 일체화되게 형성된 탄성을 갖는 텐션리브(5)의 탄력에 의해 누르는 키버튼(3)만 하강하는 것이며 주위의 다른 키버튼은 작동하지 않게 된다.At this time, since the key button 3 is pushed from the upper side, only the key button 3 pressed by the elasticity of the tension rib 5 having elasticity formed to be integrally opposite to both ends when descending, and the other key buttons around You will not.
이후 키버튼(3)을 누르고 있던 힘을 제거하면 텐션리브(5)가 자체 탄력에 의해 원위치로 복원되며 키버튼(3)이 상향으로 이동하여 원위치된다. 이때 버튼 프레임(1)에 일체로 형성된 키버튼(3)의 하단 외측에 형성된 걸림턱(4)이 본체하우징(7)의 하단에 닿게되므로 키버튼(3)이 본체하우징(7)의 구멍(8)에서 약간 돌출되며 더이상 외부로 이탈되는 것을 방지하게 된다.After removing the force holding the key button 3, the tension rib 5 is restored to its original position by its elasticity and the key button 3 is moved upward to its original position. At this time, the locking jaw (4) formed on the bottom outer side of the key button (3) integrally formed in the button frame (1) touches the bottom of the main body housing (7), so that the key button (3) is a hole of the main body housing (7) In 8) it protrudes slightly and prevents it from falling out anymore.
상기와 같은 본 발명에 의하면 다수개의 키버튼을 하나의 버튼 프레임에 일치화하여 본체하우징에 설치함으로써 부품수를 줄여 조립성이 단순화될 뿐아니라 미숙련자도 쉽고 정확하게 조립할 수 있어 키버튼의 오조립을 방지할 수 있으므로 작업능률을 향상시킬수 있으며, 키버튼의 연결을 텐션리브로 형성하여 항상 본체하우징에 지지되도록 하여 흔들림을 방지하고 키버튼이 일정한 간격으로 인해 키버튼의 위치를 균일하게 할 수 있어 기기의 신뢰성을 향상시킬수 있는 잇점이 있다.According to the present invention as described above, by matching a number of key buttons to a single button frame and installed in the body housing, not only the number of parts can be simplified, but also the assemblability can be simplified, even inexperienced users can be easily and accurately assembled to prevent the misassembly of the key buttons. It is possible to improve work efficiency, and it is possible to make the key button connection by tension rib so that it is always supported by the main body housing to prevent shaking and the key button can be uniformly positioned due to the regular interval. There is an advantage that can be improved.
