본 고안은 전자 키보드(key board)에서 건반 및 건반 접점부를 조립하는 것으로, 특히 상면과 저면에 건반의 상하 동작을 부드럽게 해주는 스폰지와 부직포를 각각 부착한 샤시의 중심부인 건반이 돌기와 접하는 위치상에 접점 고무의 접점부가 돌출되는 구멍을 형성하고, 구멍의 저면에 형성된 삽입홈에 끼워진 접점 고무의 아래에는 배면의 끼움홈을 통해 인쇄 회로기판을 삽입하여 본체의 주 회로기판과 연결하여서 샤시의 전,후방에 다수 형성한 나사공을 통하여 본체에 고정하도록 함으로써 부품의 수를 줄이고 스크류의 사용을 줄여 조립공정이 간단해지도록 한 전자 키보드의 건반에 관한 것이다.The present invention is to assemble the keyboard and the keyboard contact portion in the electronic keyboard (key board), in particular, the contact point on the position where the keyboard, which is the center of the chassis attached to the sponge and non-woven fabric to smooth the vertical movement of the keyboard on the upper and lower surfaces, respectively, the contact with the projection A hole is formed in which the rubber contact portion protrudes, and a printed circuit board is inserted under the contact rubber inserted into the insertion groove formed in the bottom of the hole through the rear insertion groove and connected to the main circuit board of the main body to connect the front and rear of the chassis. The present invention relates to a keyboard for an electronic keyboard, which reduces the number of parts and uses screws to simplify the assembly process by fixing to a main body through a plurality of screw holes formed therein.
종래에는 전자 키보드의 건반과 접점부가 함께 이루어진 구조가 아니므로 브래킷 등을 이용하여 건반을 본체에 조립 고정하고 본체의 내부에서 접점 고무와 회로기판으로 구성된 건반 접점부를 여러개의 나사로 고정하였으나 이는 건반의 조립과 건반 접점부의 조립이 별도로 이루어져 건반의 조립 공정이 복잡해짐은 물론, 건반을 조립하기 위해 많은 스크류를 사용하고, 다시 접점부를 별도의 스크류를 사용하여 조립 고정해야 하고, 건반과 접점부를 일치시키기 위해 신경을 써야 하는등 조립과정에 많은 불편함이 있으며 수리나 부품을 교환할때에도 많은 번거로움이 있었다.Conventionally, since the keyboard and the contact part of the electronic keyboard are not formed together, the keyboard is fixed to the main body by using a bracket or the like, and the key contact part composed of the contact rubber and the circuit board is fixed inside the main body with several screws. As the assembly of the keyboard contacts is performed separately, the assembly process of the keyboard is complicated, and a large number of screws are used to assemble the keyboard, and the contacts must be assembled and fixed again using a separate screw. There are a lot of inconveniences in the assembly process, such as the need to pay attention, and a lot of trouble in repairing or replacing parts.
이와 같은 종래의 단점을 보완하기 위한 본 고안은 상면과 저면에 스폰지와 부직포를 접착한 샤시의 중앙부에는 백색, 흑색의 건반의 저면에 형성한 돌기와 접하는 위치에 구멍을 뚫어야 저면의 삽입홈에 끼워진 접점 고무의 접점이 돌출되도록 하는 한편, 접점고무는 끼움홈을 통해 삽입된 인쇄 회로기판이 아래에서 지지하도록 하고, 인쇄회로 기판과 본체의 주회로 기판과 아래에서 지지하도록 하고, 인쇄회로 기판과 본체의 주회로 기판과 연결한 상태에서 샤시의 전,후방의 나사공을 이용해 스크류로 본체에 고정함으로써 건반과 건반 접점부가 함께 조립되고 부품의 수를 줄이면서 스크류의 사용을 줄여 조립 공정이 간단해지도록 한 것으로, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention for compensating the above disadvantages is a contact point inserted into the insertion groove of the bottom should be punched in the position in contact with the projection formed on the bottom of the white, black keys in the center of the chassis bonded to the sponge and the non-woven fabric on the top and bottom While the rubber contacts protrude, the contact rubber supports the printed circuit board inserted through the fitting groove from below, and supports from below the main circuit board of the printed circuit board and the main body, By connecting the main circuit board to the main body with screws on the front and rear of the chassis, the keyboard and the keyboard contacts are assembled together, reducing the number of parts and simplifying the assembly process. If this is described in detail by the accompanying drawings as follows.
샤시(1)의 상면과 하면에 스폰지(2)와 부직포(3)를 각각 부착하여 건반(4)의 하면과 샤시(1)의 안내홈(1-1)을 통한 걸림턱(4-1)이 부드럽게 접촉되도록하고, 건반(4)의 저면에 형성한 돌기(4-2)와 접하는 위치인 샤시(1)의 중앙부에 구멍(1-2)을 다수 천공하여 하부의 삽입홈(1-3)을 통하여 삽입되는 접점고무(5)의 접점(5-1) 이 돌출되도록하며, 접점고무(5)의 아래에는 주회로기판(6)과 콘넥터(7)를 연결되어 신호를 전달하며 전자부품(8-1)과 단자(8-2)가 다수 부착된 인쇄회로 기판(8)이 샤시(1)의 끼움홈(1-4)을 통해 끼워지면서 유지하도록하고, 전방의 나사공(1-5)을 통해 스크류(9)로 본체(10)에 고정되는 샤시(1)의 후방은 건반(4)의 끝단(4-3)이 단턱(1-6)에 걸리도록한 상태에서 나사공(1-7)을 통해 스크류(11)로 나사조임하여 건반(4)과 같이 본체(10)에 고정한 것이다.Attaching the sponge 2 and the nonwoven fabric 3 to the upper and lower surfaces of the chassis 1, respectively, the locking jaw 4-1 through the lower surface of the keyboard 4 and the guide groove 1-1 of the chassis 1; In the center of the chassis 1, which is in contact with the projection 4-2 formed on the bottom surface of the keyboard 4, by making a plurality of holes 1-2. Contact 5-1 of the contact rubber (5) inserted through the) to protrude, and the main circuit board 6 and the connector (7) is connected to the bottom of the contact rubber (5) to transmit a signal (8-1) and the printed circuit board (8) having a plurality of terminals (8-2) attached to each other through the fitting grooves (1-4) of the chassis (1). 5, the rear of the chassis 1, which is fixed to the main body 10 with a screw 9, is screwed in a state where the end 4-3 of the keyboard 4 is caught by the step 1-6. 1-7) is screwed into the screw 11 and fixed to the main body 10, like the keyboard (4).
이와같은 본 고안은 전자 키보드에서 샤시(1)의 후방에 형성한 단턱(1-6)에 건반(4)의 끝단(4-3)이 걸리도록한 상태에서 건반(4)의 돌기(4-2)와 접하는 샤시(1)의 구멍(1-2)에 접점고무(5)의 접점(5-1)을 돌출시키고, 접점고무(5)의 아래쪽에는 접점(5)과 단자(8-2)가 접하는 인쇄회로기판(8)를 끼움홈(1-4)을 통해 삽입한 것으로, 사용자가 건판(4)을 누르면 제2도에 도시된 바아 같이 건반(4)의 저면이 스폰지(2)와 접하면서 부드럽게 하향 이동하여 돌기(4-2)가 접점고무(5)의 접점(5-1)을 눌러 주면서 접점고무(5)의 내부에 내장된 도전성 고무와 인쇄회로기판(8)의 단자(8-2)가 서로 접속되도록하고, 이에 따라 이 신호가 전자부품(8-1)을 통하고 콘넥터(7)를 통해 주회로 기판(6)으로 전달된다.The present invention as described above is a projection (4-) of the keyboard 4 in a state in which the end 4-3 of the keyboard 4 is caught by the step 1-6 formed at the rear of the chassis 1 in the electronic keyboard. 2) The contact 5-1 of the contact rubber 5 protrudes through the hole 1-2 of the chassis 1 in contact with the chassis, and the contact 5 and the terminal 8-2 are disposed below the contact rubber 5 ) Is inserted into the printed circuit board (8) through the fitting groove (1-4), when the user presses the dry plate 4, the bottom surface of the keyboard (4) is sponge (2) as shown in FIG. The terminal of the conductive rubber and the printed circuit board (8) embedded in the contact rubber (5) while the projection (4-2) presses the contact (5-1) of the contact rubber (5) while gently touching (8-2) are connected to each other, and thus this signal is transmitted to the main circuit board 6 through the electronic component 8-1 and through the connector 7.
그리고 사용자가 건반(4)을 누르던 상태에서 손을떼면 건반(4)의 자체 탄성으로 원 상태로 환원되면서 접점고무(5)의 접점(51)을 접속시키던 상태에서 해제되고, 건반(4)의 걸림턱(4-1)이 샤시(1)의 하면에 부착한 부직포(3)와 접하면서 부드럽게 상향 이동이 중단되는 것이다.Then, when the user releases his hand while pressing the key 4, the key 4 is released to its original elasticity and released in the state of connecting the contact 51 of the contact rubber 5, and the key 4 While the engaging jaw (4-1) is in contact with the nonwoven fabric (3) attached to the lower surface of the chassis (1) is to smoothly stop the upward movement.
이와같이 건반(4)의 돌기(4-2)와 접하는 샤시(1)의 구멍(1-2)에는 인쇄회로기판(8)에 지지되며 단자(8-2)와 접하는 접점고무(5)의 접점(5-1)이 돌출되도록하고, 샤시(1)의 상면과 저면에 스폰지(2)와 부직포(3)를 접착하여 건반(4)의 상하 이동이 부드럽게 이동되도록 함으로써 본체(10)에 샤시(1)를 나사조임으로 조립하고, 샤시(1)에는 접점고무(5)와 인쇄회로기판(8)을 끼워 맞추도록하여 부품수를 줄이고, 조립과 분해가 간단하여 제작이나 수리가 용이하며, 건반(4)의 상하 이동으로 인한 충격과 소음을 극소화한 것이다.In this way, the hole 1-2 of the chassis 1 in contact with the projection 4-2 of the keyboard 4 is supported by the printed circuit board 8 and is in contact with the contact rubber 5 in contact with the terminal 8-2. (5-1) to protrude, and adhere the sponge (2) and the non-woven fabric (3) to the upper and lower surfaces of the chassis 1 so that the vertical movement of the keyboard (4) is moved smoothly to the chassis ( 1) is assembled by screwing and the contact rubber (5) and the printed circuit board (8) are fitted to the chassis (1) to reduce the number of parts, and the assembly and disassembly are simple, making it easy to manufacture or repair the keyboard. The impact and noise caused by the vertical movement of (4) are minimized.
