본 고안은 TV 수상기나 오디오기기, 비디오 기기 등 각종 가전제품에 내장된 터치식 택트스위치(Tact Switch)를 작동시키기 위한 놉의 구조에 관한 것으로, 특히 놉이 거의 직선운동을 하면서 진퇴되게 하여 스위치의 작동이 확실히 이루어질 수 있게 한 것이다.The present invention relates to a structure of a knob for operating a touch-type tact switch (Tact Switch) built in various home appliances such as TV receivers, audio equipment, video equipment, in particular, the knob is moved in a straight line to move back and forth It is to make sure that it works.

종래에 일반적으로 사용되어온 택트스위치용 놉은 제3도 및 제4도에 도시한 바와 같이 기기의 샷시에 고정되는 몸체(11)와 몸체(11)의 일측에 연결되어 힌지작용을 하는 탄성부(12), 그리고 탄성부(12)의 끝부분에 연결되어 직접 택트스위치에 접속하는 버튼부(13)로 구성되어 있다.Conventionally used tact switch knobs are connected to one side of the body 11 and the body 11 fixed to the chassis of the device as shown in FIGS. 12) and a button portion 13 connected to the end of the elastic portion 12 and directly connected to the tact switch.

따라서 사용자가 버튼부(13)를 누르면 버튼부(13)가 전진하여 P.C.B(9)에 고정된 스위치(7)의 접점(8)과 접속하여 스위치를 온시키고 버튼부(13)를 누름상태에서 해제하면 탄성부(12)에 의해 버튼부(13)가 다시 원위치로 되돌아오게 된다.Therefore, when the user presses the button portion 13, the button portion 13 advances and is connected to the contact point 8 of the switch 7 fixed to the PCB 9 to turn on the switch and press the button portion 13. When released, the button portion 13 is returned to the original position by the elastic portion 12.

그러나 이러한 종래의 놉은 버튼부(13)가 단지 탄성부(12)의 연결점을 중심으로 회전운동을 하면서 스위치를 작동시키는 구조이어서 장기간 사용시 탄성부(12)의 연결점 부분이 약화되어 파손될 우려가 있으며, 버튼부(13)의 회전 작동시 곡률반경이 작고 이에 따라 제4도와 같이 버튼부(13)의 후면이 스위치(7)의 접점(8)에 부분적으로 접속하는 경우가 많아 스위치의 작동이 정확히 이루어지지 않을 우려가 많다.However, such a conventional knob has a structure in which the button 13 only operates the switch while rotating around the connection point of the elastic part 12, so that the connection point part of the elastic part 12 may be weakened and damaged when used for a long time. When the button 13 is rotated, the radius of curvature is small, and as a result, as shown in FIG. 4, the back of the button 13 is partially connected to the contact 8 of the switch 7. There is a lot of fear that it will not work.

또한 제4도와 같이 버튼부(13)의 후면과 스위치(7)의 접점(8)이 점접촉을 이루므로 장기간 사용시 버튼부(13) 후면이 비정상적으로 마모되어 스위치의 작동이 더욱 불안해지며, 장기간 사용시 버튼부의 원위치 작동이 불안정하여 2개 이상의 놉이 설치되는 경우 제품의 외관이 불량해는 문제도 있다.In addition, as shown in FIG. 4, since the back of the button 13 and the contact point 8 of the switch 7 make point contact, the back of the button 13 is abnormally worn when used for a long period of time, thereby making the operation of the switch more unstable. In case of using two or more knobs because of unstable operation of the button part, the appearance of the product is poor.

본 고안은 종래의 이와 같은 문제점을 해소하기 위해 탄성부의 곡률반경을 최대한으로 크게 하여 버튼부가 거의 직선적으로 작동할 수 있게 한 것인 바, 이를 첨부된 도면 제1도 내지 제2도에 의해 더욱 상세히 설명하면 다음과 같다.The present invention is to solve the problems of the prior art by the maximum radius of curvature of the elastic portion to enable the button portion to operate almost linear, which is described in more detail by the accompanying drawings 1 to 2 The explanation is as follows.

놉 몸체(1)의 일측에 대략 ""자 형으로 된 탄성부(2)를 대향되게 형성하여 각 탄성부(2)의 상향 절곡된 끝부분에 버튼부(3)를 연결하고 버튼부(3)의 후면에는 접점 가이드돌기(4)를 형성하여서 된 것이다.Approximately one side of the knob body 1 "The elastic portion (2) formed in the shape of the opposite to connect the button portion (3) to the upper bent end of each elastic portion (2) and the contact guide projection (4) on the back of the button portion (3) It was formed by forming.

도면 중 미 설명부호 5는 기판 또는 전면판넬, 6은 보스, 10은 놉 체결용 스크류이다.In the drawings, reference numeral 5 denotes a substrate or a front panel, 6 a boss, and 10 a screw for fastening a knob.

이와 같이 구성된 본 고안은 몸체(1)의 일측에 ""자 형으로 된 한쌍의 탄성부(2)가 서로 대향되게 연결되어 있고 각 탄성부(2)의 상향 절곡된 끝부분에 버튼부(3)가 연결되어 있으므로 버튼부(3)를 누를 때 탄성부(2)에 걸리는 원운동이 상,하로 균등하게 작용하게 되고 이에 따라 탄성부(2)의 곡률반경이 최대한으로 크게 되어 버튼부(3)가 거의 직선운동을 하게 된다.The present invention configured as described above has one side of the body (1). "A pair of elastic parts (2) of the shape of the elastic is connected to each other and the button portion (3) is connected to the upper bent end of each elastic portion (2) elasticity when pressing the button portion (3) The circular motion applied to the part 2 acts equally up and down, and accordingly, the radius of curvature of the elastic part 2 is maximized to make the button part 3 almost linearly move.

따라서 버튼부(3)를 누르면 제2도 (b)와 같이 버튼부(3)의 후면이 스위치(7)의 접점(8)과 거의 전체적으로 접속하게 되므로 스위치를 정확히 동작시킬 수 있게 되고 버튼부(3)의 후면에 형성된 접점 가이드 돌기(4)에 의해 스위치의 작동이 더욱 확실해지며, 장기간 사용시에도 탄성부(2)가 파손될 우려가 없음은 물론 버튼부(3)가 비정상적으로 마모될 우려가 없다.Therefore, when the button portion 3 is pressed, the back of the button portion 3 is almost entirely connected to the contact point 8 of the switch 7, as shown in FIG. 2 (b), so that the switch can be operated correctly and the button portion ( The contact guide protrusions 4 formed on the rear side of 3) make the operation of the switch more reliably, and there is no fear that the elastic portion 2 will be damaged even during long-term use, and there is no fear that the button portion 3 will be abnormally worn. .

또한 장기간 사용시에도 버튼부(3)가 항상 일정한 위치로 원위치하게 되어 제품의 외관이 양호해지는 이점이 있다.In addition, there is an advantage that the appearance of the product is good because the button portion 3 is always in the original position even when used for a long time.
