본 고안은 라디오, 카세트 테이프 레코더, VCR 텔리비젼등에 사용되는 푸시버튼 스위치에 관한 것으로, 특히 그 내부에 설치되는 접점판에 있어서, 고정접점과의 접속이 보다 양호하도록 함에 주안점을 둔 것이다.The present invention relates to a pushbutton switch used in a radio, a cassette tape recorder, a VCR television, and the like, and in particular, in a contact plate installed therein, the main focus is to provide a better connection with a fixed contact.

종래 푸시버튼 스위치의 접점판 구조를 살펴보면 도면 제1도 및 제2고에서와 같이 일방향으로 만곡하는 접점판(1)에 원주 방향으로 향하는 2개의 슬릿(2A, 2B)을 평행하게 절결한 사이에 가동접점부(3)를 가지며, 상기의 접점판의 슬릿(2A, 2B) 외측방으로 가동접점부(3)와 반대 방향으로 만곡시켜 상접 접점부(4A, 4B)를 일체로 연설하고 있는 접점판(1)의 양단 연설부(5A, 5B)와 상접 접점부(4A, 4B)간에 절곡선부(41, 42, 43, 44)를 형성시켜 그 절곡선부가 슬릿에 대해 하향경사 시켜서 된 구조이다.Looking at the contact plate structure of a conventional pushbutton switch, as shown in FIGS. 1 and 2, the two slit (2A, 2B) facing in the circumferential direction parallel to the contact plate (1) curved in one direction between The contact which has the movable contact part 3, and is curved in the opposite direction to the movable contact part 3 to the outer side of the said slit 2A, 2B of the said contact board, and integrally extends the upper contact parts 4A, 4B. The bent portions 41, 42, 43 and 44 are formed between the both ends 5A and 5B of the plate 1 and the upper contact portions 4A and 4B, and the bent portion is inclined downward with respect to the slit. .

한편, 도면 제2도에서와 같이 상자형의 스위치 본체(100)의 저면 양측에 제1고정접점(4A', 4B')을 둔 제1고정 단자(40)의 중앙에 제2고정접점(3')을 제2고정단자(30)를 가지며 개구된 상면에는 저부에 구상돌부(201)를 가지는 푸시버튼(200)이 상부로 이탈규제되게 삽입 설치한 커버(101)가 고정설치되어 내부에는 접점판(1)의 가동접점부(3)가 푸시버튼의 구상돌부(201)에 당접하고 그 저부에 제2고정접점(3')이 위치되며 상접 접점접점부(4A, 4B)는 저면의 제1고정접점(4A', 4B')에 상접되게 조립되어 있다.Meanwhile, as shown in FIG. 2, the second fixed contact point 3 is located at the center of the first fixed terminal 40 having the first fixed contact points 4A 'and 4B' disposed on both sides of the bottom of the box-shaped switch body 100. ') Has a second fixed terminal 30 and the cover 101 is inserted into the upper surface opened so that the push button 200 having a spherical protrusion 201 at the bottom is separated from the upper part is fixedly installed and contacts therein. The movable contact portion 3 of the plate 1 is in contact with the spherical protrusion 201 of the pushbutton, and the second fixed contact point 3 'is located at the bottom thereof, and the upper contact contact points 4A and 4B are formed at the bottom surface. It is assembled so as to be in contact with one fixed contact 4A ', 4B'.

따라서, 푸시버튼(200)을 누름에 따라 구상돌부(201)가 가동접점부(3)를 눌러 만곡반향과 반대방향으로 압압 변향시켜 가동접점부(3)가 제2고정접점(3')에 당접되게 하며, 이때 가동접점부(3)는 항시 상부로 원위치되려는 탄성력을 발휘하기 때문에 푸시버튼(200)을 누르는 힘을 해제시킴과 동시에 원상복귀된다.Accordingly, as the pushbutton 200 is pressed, the spherical protrusion 201 pushes the movable contact portion 3 to be pressure-shifted in the opposite direction to the curved echo, so that the movable contact portion 3 is connected to the second fixed contact 3 '. In this case, since the movable contact portion 3 exerts an elastic force to be always returned to the upper portion, the movable contact portion 3 releases the force for pressing the pushbutton 200 and returns to its original position.

그러나 이때, 양측 제1고정접점부(4A, 4B)는 도면 상축으로 만곡되고, Y축으로 하향경사지게 구성되므로써 제1고정접점(4A, 4B')과의 접속이 고정접점부의 양가장자리에서 점접속으로, 이루어지게 되므로써 그 접속이 불안하여 푸시버튼 스위치의 불량률이 많았던 것이다.However, at this time, since the first fixed contact portions 4A and 4B on both sides are curved to the upper axis of the drawing and are inclined downward on the Y axis, the connection with the first fixed contacts 4A and 4B 'is connected at both edges of the fixed contact portion. As a result, the connection was unstable and the defective rate of the pushbutton switch was many.

따라서 본 고안은 이상과 같은 문제점을 해결하고자 제1고정접점과 접하는 상접접점부의 양가장자리가 선접촉되게하여 제1고정 접점과 상접 접점부 간의 접속이 안정되게하여 궁극적으로는 푸시버튼 스위치의 불량률을 개선하기 위한 목적으로 안출된 것이다.Therefore, in order to solve the above problems, both of the upper contact portions of the upper contact point contacting the first fixed contact point are brought into line contact so that the connection between the first fixed contact point and the upper contact point point is stable and ultimately, the failure rate of the pushbutton switch is improved. It is intended to improve.

이하에서 이를 첨부 도면에 의해 보다 상세히 설명하면 다음과 같다.Hereinafter, this will be described in more detail with reference to the accompanying drawings.

푸시버튼 스위치의 접점판을 구성함에 있어서, 일방향으로 만곡하는 접점판(1)의 중앙에 가동접점부(3)를 가지게 2개의 슬릿(2A, 2B)을 평행하게 절결하고, 상기 슬릿(2A, 2B) 외측방의 양측 소정위치에는 슬릿과 직교되는 방향으로 절곡선부(61, 62, 63, 64)를 형성하며 가동접점부(3)와 반대 방향으로 만곡되는, 중앙에 상기 가동접점부(3)와 같은 방향으로 절곡 구성된 곡면부(71, 72)의 양측 각각에는 경사평면(81, 82, 83, 84)을 가지게 슬릿으로 부터 외측방으로 협소해지며 하향된 절곡선부(91, 92, 93, 94)를 형성하여서된 상접점부(9A, 9B)를 구비하여서 된 것이다.In constructing the contact plate of the pushbutton switch, two slits 2A and 2B are cut out in parallel to have the movable contact portion 3 in the center of the contact plate 1 curved in one direction, and the slits 2A, 2B) The movable contact portion 3 is formed at both centers of the outer side to form bent portions 61, 62, 63, and 64 in a direction orthogonal to the slit and bend in the opposite direction to the movable contact portion 3. On both sides of the curved portions 71 and 72 configured to be bent in the same direction, the bent portions 91, 92, 93, narrowed outward from the slit to have inclined planes 81, 82, 83, 84, The upper contact portions 9A and 9B formed by forming 94 are provided.

이때, 절곡선부의 슬릿에 대한 각도(θ)는 90도 보다 크고 180도 보다는 작은 범위내에서 형성된다.At this time, the angle θ with respect to the slit of the bent portion is formed within a range larger than 90 degrees and smaller than 180 degrees.

이상과 같이 구성된 본 고안의 작용효과를 살펴보면 도면 제4도 (a)의 상태에서 푸시버튼(200)을 누르면 구상돌부(201)가 가동접점부(3)를 눌러 도면 제3도의 (b)에서 표시된 "A" "B" "B'"부가 미세하게 상승되면서 상접 접점부(9A, 9B)의 중앙 곡면부(71, 72)가 도면의 화살표 방향인 외측방으로 힘이 미치면서 상접 접점부(9A, 9B)의 경사평면(81, 82, 83, 84) 가장 자리가 제1고정접점부(4A', 4B')에 안전하게 밀착되어 접속된다.Looking at the operation and effect of the present invention configured as described above when the push button 200 in the state of Fig. 4 (a) the spherical protrusion 201 by pressing the movable contact (3) in Fig. 3 (b) As the displayed "A" "B" "B '" portion is slightly raised, the center curved portions 71 and 72 of the upper contact portions 9A and 9B exert a force toward the outside in the direction of the arrow in the drawing, and the upper contact portion ( The edges of the inclined planes 81, 82, 83, 84 of 9A, 9B are securely connected to the first fixed contact portions 4A ', 4B' and connected.

이때 접속은 선접촉이 이루어지게되어 그 접속이 안정됨은 물론 절곡선부(91, 92, 93, 94)에 의해 접시 스프링의 운동형상인 크리크 음이 발생됨과 동시에 정확한 작동력이 얻어지게 된다.At this time, the connection is made in line contact, the connection is not only stable, but also the bending sound (91, 92, 93, 94) the creep sound of the movement shape of the disc spring is generated and at the same time the correct operating force is obtained.

이상과 같이 구성되고 작동되는 본 고안은 푸시버튼 스위치의 접점판에 있어서 상접 접점부의 중앙에 곡면부를 두어 접속력을 양호하게 함과 동시에 크리크 음의 발생이 확실히 이루어지게 하여 종래의 접점판의 구조상 취약점인 접속불량을 일소하게한 매우 유용한 고안인 것이다.The present invention constructed and operated as described above has a curved portion at the center of the upper contact portion in the contact plate of the pushbutton switch to improve the connection force and at the same time ensure the generation of a click sound, which is a weak point in the structure of the conventional contact plate. It is a very useful design to eliminate the poor connection.
