이하, 본 고안의 구성을 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the configuration of the subject innovation in detail as follows.
제 1 도는 본 고안 기판고정장치의 구조를 설명하기 위한 분리 사시도이고, 제 2a,b,c 도는 평면도 및 단면도로써, 원통형의 본체(1) 하부에 샤시(2)의 걸림구멍(2a)으로 걸림되는 걸림홈(3)을 형성시킨 탄성편(4a) (4b)이 형성되고, 이 탄성편(4a), (4b)의 중앙으로 절취홈(5)이 형성되어 상기 탄성편(4a) (4b)에 탄성력이 부여되며, 상기 본체(1)의 내부에는 안내구멍(6)이 형성되어 이 안내구멍(6)의 원주방향으로 요홈(7)이 형성되고, 상기 요홈(7) 양측에서 안내구멍(6)의 길이방향으로 슬라이드 홈(8a), (8b)면상에는 단턱(9a) 및 누름턱(9b)이 형성된다.1 is an exploded perspective view for explaining the structure of the substrate fixing apparatus of the present invention, and 2a, b, and c are plan views and cross-sectional views, which are caught by the locking holes 2a of the chassis 2 under the cylindrical body 1. The elastic pieces 4a and 4b which form the engaging grooves 3 to be formed are formed, and the cutout groove 5 is formed in the center of these elastic pieces 4a and 4b, and the elastic pieces 4a and 4b are formed. ) Is provided with an elastic force, a guide hole 6 is formed inside the main body 1, and a groove 7 is formed in the circumferential direction of the guide hole 6, and guide holes are formed at both sides of the groove 7. Steps 9a and 9b are formed on the slide grooves 8a and 8b in the longitudinal direction of (6).
또한, 상기 안내구멍(6)에 안내되는 레버(10)의 원통부(11)에 걸림돌기(11a) (11b)가 양측으로 형성되어 요홈(7)에 끼워지고, 상기 원통부(11)를 돌리거나 누르도록 되고 기판(12)의 삽입구(12a)에 끼워지는 누름편(13)이 원통부(11)와 축(14)으로 연결된 구성이다.In addition, the engaging projections 11a and 11b are formed on both sides of the cylindrical portion 11 of the lever 10 guided by the guide hole 6 so as to fit in the groove 7 and the cylindrical portion 11 is closed. The pressing piece 13 to be turned or pressed and fitted into the insertion hole 12a of the substrate 12 is connected to the cylindrical portion 11 by the shaft 14.
이와같이 구성된 본 고안은 전기, 전자제품이나 정보통신분야등의 기기본체 내부에 각종부품이나 회로패턴들이 장착되는 기판을 샤시에 고정시킴에 있어서, 제 1 도 내지 제 3 도에서와 같이 기판(12)에 레버(10)의 누름편(13)이 일방향으로만 끼워질수 있는 삽입구(12a)를 형성하고, 상기 기판(12)이 고정되는 샤시(2)에는 본체(1)의 탄성편(4a), (4b)이 끼워질수 있는 걸림구멍(2a)을 형성시킨 다음, 제 3 도와 같이 샤시(2)의 걸림구멍(2a)에 본체(1)의 탄성편(4a), (4b)을 끼우게 되면 이 탄성편(4a), (4b)은 절취홈(5)에 의해 탄성이 부여되므로 탄성편(4a), (4b)의 걸림홈(3)이 걸림구멍(2a)에 약간 걸림유지된 상태로 끼워지게 된다.The present invention configured as described above secures a substrate in which various components or circuit patterns are mounted in a chassis of an apparatus such as an electric, electronic product, or information and communication field in the chassis. As shown in FIGS. The pressing piece 13 of the lever 10 is formed in the insertion hole 12a which can be fitted in only one direction, the chassis 2 to which the substrate 12 is fixed to the elastic piece 4a of the main body 1, When the engaging holes 2a into which the 4b can be fitted are formed, and then the elastic pieces 4a and 4b of the main body 1 are inserted into the engaging holes 2a of the chassis 2 as shown in the third diagram. The elastic pieces 4a and 4b are provided with elasticity by the cutout grooves 5, so that the locking grooves 3 of the elastic pieces 4a and 4b are slightly held in the locking holes 2a. Will be fitted.
상기와 같이 샤시(1)의 걸림구멍(2a)에 본체(1)가 끼워진 상태에서 기기내에 설치할 기판(12)의 삽입구(12a)를 레버(10)의 누름편(13)에 끼우고 누름편(13)을 좌,우 어느한쪽으로는 90°회전시키게 되면 제 2b 도에서와 같이 본체(1)의 안내구멍(6)에 형성된 요홈(7)상에 있던 원통부(11)양측의 걸림돌기(11a), (11b)가 슬라이드홈(8a), (8b)을 따라 하강하게 된다.As described above, the insertion hole 12a of the substrate 12 to be installed in the apparatus is inserted into the pressing piece 13 of the lever 10 while the main body 1 is fitted into the locking hole 2a of the chassis 1. When the 13 is rotated 90 ° to either of the left and right sides, as shown in FIG. 2B, the protrusions on both sides of the cylindrical portion 11 on the groove 7 formed in the guide hole 6 of the main body 1 are shown. 11a and 11b are lowered along the slide grooves 8a and 8b.
따라서, 제 3 도에 나타낸 가상선 상태와 같이 원통부(11)의 걸림돌기(11a), (11b)가 하강하면서 슬라이드홈(8a), (8b)상에 형성된 단턱(9a)을 지나 누름턱(9b)을 누르게 되므로, 절취홈(5)에 의해 탄성력이 부여된 탄성편(4a), (4b)이 밀려 샤시(2)의 걸림구멍(2a)에 더욱 밀착되고, 걸림구멍(2a)의 내측에 걸림홈(3)이 끼워지면서 눌리어 고정되며, 레버(10)의 누름편(13)이 90°회전된 것에 의해 기판(12)의 삽입구(12a)와 어긋나 걸림유지 되어 기판이 빠지지 않게되므로 제 4 도와 같이 샤시(2)에 기판(12)이 견고히 고정된 상태가 된다.Accordingly, as shown in FIG. 3, the pressing projections 11a and 11b of the cylindrical portion 11 descend as they pass through the stepped portions 9a formed on the slide grooves 8a and 8b. Since 9b is pressed, the elastic pieces 4a and 4b to which the elastic force is imparted by the cutting groove 5 are pushed further to be in close contact with the locking holes 2a of the chassis 2. As the locking groove 3 is fitted into the inner side, it is pressed and fixed, and the pressing piece 13 of the lever 10 is rotated by 90 ° so as to be disengaged from the insertion hole 12a of the substrate 12 so that the substrate is not pulled out. Therefore, the substrate 12 is firmly fixed to the chassis 2 as in the fourth diagram.
또한, 상기와 같이 샤시(2)에 기판(12)이 고정된 상태에서 기판(12)을 분리하고자 할 경우는 레버(10)의 누름편(13)을 잡아당기게 되면, 슬라이드홈(8a), (8b)의 누름턱(9b)을 누르고 있던 원통부(11)의 걸림돌기(11a)(11b)가 상승하게 되므로 탄성편(4a), (4b)이 눌림해제되어 원위치되고(제 3 도의 실선상태), 이어서 당기고 있던 누름편(13)을 좌, 우 어느한쪽으로 90°회전시키면 기판(12)의 삽입구(12a)와 레버(10)의 누름편(13)이 일치되어 기판(12)은 레버(10)로 부터 분리되며, 샤시(2)의 걸림구멍(2a)에서 몸체(1)의 탄성편(4a), (4b)이 누림해제 되어 있으므로 샤시(2)와 몸체(1)를 쉽게 분리시킬수가 있다.In addition, when the substrate 12 is fixed to the chassis 2 as described above, when the substrate 12 is to be removed, when the pressing piece 13 of the lever 10 is pulled out, the slide groove 8a, Since the engaging projections 11a and 11b of the cylindrical portion 11 holding down the pressing jaw 9b of (8b) are raised, the elastic pieces 4a and 4b are released to their original positions (solid line in Fig. 3). State), and then, when the pressing piece 13 that is being pulled is rotated 90 degrees to either the left or the right side, the insertion hole 12a of the substrate 12 and the pressing piece 13 of the lever 10 coincide with each other. It is separated from the lever 10, and since the elastic pieces 4a and 4b of the body 1 are released from the engaging holes 2a of the chassis 2, the chassis 2 and the body 1 are easily removed. Can be separated
이상에서와 같이 본 고안의 기판고정장치는 본체에 형성된 탄성편과 이 본체내에서 작동하는 레버의 누름편으로서, 샤시에 간단한 조작으로 기판을 고정 및 분리시킬 수 있게 됨에 따라 조립공정의 시간을 단축시킬 수 있어 조립능률 및 생산성이 증대되고, 종래의 나사로 고정하는 방법에 의한 불량생산이 줄어 손실이 절감되며, 아프터써비스(A/S)등 소비자의 신뢰도를 향상시킬 수 있는 고안인 것이다.As described above, the substrate fixing device of the present invention is an elastic piece formed on the main body and a pressing piece of a lever operating in the main body, and thus the substrate can be fixed and separated by simple operation in the chassis, thereby shortening the assembly process time. It is possible to increase the assembly efficiency and productivity, to reduce the loss by reducing the poor production by the conventional screw fixing method, it is designed to improve the customer's reliability, such as after-sales (A / S).
