본 고안은 전자제품의 메인 PCB기판 조립구조에 관한 것으로, 특히 샤시에 조립되는 메인 PCB기판의 선단 중간부를 받쳐주어 메인 PCB기판의 처짐을 방지하여 스위치 동작일정하게 유지, 제품의 품질안정을 유지하는 동시에 작업의 단순화를 도모하도록 안출한 전자제품의 메인 PCB기판의 처짐방지장치에 관한 것이다.The present invention relates to the assembly structure of the main PCB board of electronic products, and in particular, it supports the middle part of the front end of the main PCB board to be assembled to the chassis to prevent sagging of the main PCB board to maintain a constant switch operation and to maintain product quality stability. At the same time, the present invention relates to a sag prevention device of a main PCB substrate of an electronic product designed to simplify the work.

일반적으로 모니터, TV 등 전자제품은 내부 바닥면에 메인 PCB기판이 조립되어 있다.In general, the main PCB board is assembled on the inner bottom of electronic products such as monitor and TV.

예컨대, 메인 PCB기판을 조립하고자 할 때, 본체에 고정설치된 샤시의 양측에 메인 PCB기판의 양측단을 조립나사로 조립하거나, 샤시의 양측벽에 조립된 기판레일에 메인 PCB기판을 끼워서 조립하도록 되어 있다.For example, when assembling the main PCB board, both ends of the main PCB board are assembled on both sides of the chassis fixed to the main body with assembly screws, or the main PCB boards are fitted to the board rails assembled on both sides of the chassis. .

그런데 메인 PCB기판의 중간부는 별도로 지지하여 주는 구조가 없어 조립 후 메인 PCB기판의 자중 및 부품의 중량에 의하여 중간부가 처지게 되므로 타부품과 접촉되어 오동작의 원인이 되거나 PCB기판의 기능을 충분히 발휘할 수 없는 문제점이 있었다.However, since the middle part of the main PCB board does not support a separate structure, the middle part sags due to the weight of the main PCB board and the weight of the parts after assembly. There was no problem.

본 고안은 이러한 종래의 문제점을 해결하고자 하는 것으로, 샤시에 조립되는 메인 PCB기판의 선단 중간부를 받쳐주어 메인 PCB기판의 처짐을 방지하는 동시에 작업의 단순화를 도모하고자 전자제품의 메인 PCB기판의 처짐방지장치를 제공하는 데 그 목적이 있다.The present invention is intended to solve such a conventional problem, and to prevent sagging of the main PCB substrate by supporting the intermediate portion of the front end of the main PCB substrate to be assembled to the chassis, and to prevent the sagging of the main PCB substrate of the electronic products to prevent the sagging. The object is to provide a device.

본 고안은 이러한 목적을 달성하기 위하여, 전방벽의 상부에 형성되는 걸림홈과, 걸림홈의 직하방에 위치되도록 바닥면에 형성되는 끼움홈으로 구성된 샤시와; 샤시의 걸림홈에 탄력있게 끼워져서 걸리도록 하는 걸림턱이 형성된 탄력핀과, 중간부에 메인 PCB기판의 선단 중간부를 받쳐주어 처짐을 방지하는 기판삽입홈과, 샤시의 끼움홈에 끼워서 빠지지 않도록 저면에 돌출되는 끼움돌기로 구성된 기판받침구로 전자제품의 메인 PCB기판의 처짐방지장치를 구성한 것이 본 고안의 특징이다.The present invention is a chassis consisting of a locking groove formed on the upper portion of the front wall, and a fitting groove formed on the bottom surface to be located directly below the locking groove to achieve this object; Resilient pins formed with locking jaws that snap into the locking grooves of the chassis, the substrate insertion grooves that support the middle portions of the front end of the main PCB to prevent sag, and the bottom surface of the chassis so as not to be pulled out. It is a feature of the present invention that the deflection prevention device of the main PCB substrate of the electronic product is constituted by a substrate support formed of a fitting protrusion protruding from the main body.

상기 샤시에는 메인 PCB기판을 조립나사로 조립하거나 별도의 기판레일을 이용하여 조립한다.In the chassis, the main PCB board is assembled with assembly screws or assembled using a separate board rail.

이하 본 고안을 첨부도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도면 제1도 내지 제4도는 본 고안의 실시예로서, 전방벽(11)의 상부에 형성되는 걸림홈(11a)과, 걸림홈(11a)의 직하방에 위치되도록 바닥면(12)에 형성되는 끼움홈(12a)으로 구성된 샤시(10)와; 샤시(10)의 걸림홈(11a)에 탄력있게 끼워져서 걸리도록 하는 걸림턱(21a)이 형성된 탄력핀(21)과, 중간부에 메인 PCB기판(30)의 선단 중간부를 받쳐주어 처짐을 방지하는 기판삽입홈(22)과, 샤시(10)의 끼움홈(12a)에 끼워서 빠지지 않도록 저면에 돌출되는 끼움돌기(23)로 구성된 기판받침구(20)로 전자제품의 메인 PCB기판의 처짐방지장치를 구성한다.1 through 4 are embodiments of the present invention, and are formed on the bottom surface 12 so as to be positioned directly below the locking groove 11a and the locking groove 11a formed in the upper portion of the front wall 11. A chassis 10 composed of fitting grooves 12a; An elastic pin 21 having a locking jaw 21a formed to elastically fit in the locking groove 11a of the chassis 10 and a middle portion of the front end of the main PCB 30 to prevent sagging. Preventing sagging of the main PCB substrate of the electronic product by the substrate support hole 20 composed of a substrate insertion groove 22 to be inserted into the fitting groove 12a of the chassis 10 and a fitting protrusion 23 protruding from the bottom so as not to fall out. Configure the device.

상기 샤시(10)에는 메인 PCB기판(30)을 양측벽(13)에 각각 조립된 별도의 기판레일(40)에 끼워서 조립한다.The chassis 10 is assembled by inserting the main PCB board 30 into separate board rails 40 respectively assembled on both side walls 13.

이와 같이 구성된 본 고안은, 샤시(10)의 전방벽(11)에 형성된 걸림홈(11a)과 바닥면(12)에 형성된 끼움홈(12a)에 기판받침구(20)의 탄력핀(21)과 끼움돌기(23)를 각각 끼워서 분리되지 않도록 조립한다.The present invention configured as described above, the elastic pin 21 of the substrate support hole 20 in the engaging groove (11a) formed in the front wall 11 of the chassis 10 and the fitting groove (12a) formed in the bottom surface 12. And fitting projections (23) are assembled so as not to separate respectively.

즉, 기판받침구(20)의 끼움돌기(23)를 샤시(10)의 끼움홈(12a)에 끼운 상태에서 기판받침구(20)의 탄력핀(21)이 샤시(10)의 걸림홈(11a)에 탄력있게 삽입한 뒤 탄력핀(21)의 걸림턱(21a)이 걸려서 이탈되지 않도록 조립하면 되는 것이다.That is, in the state in which the fitting protrusion 23 of the substrate support hole 20 is inserted into the fitting groove 12a of the chassis 10, the elastic pin 21 of the substrate support hole 20 is engaged with the locking groove of the chassis 10 ( 11a) is inserted into the elastic resilient pin 21 is to be assembled so as not to be caught off the locking jaw (21a) of the catch.

그 후, 메인 PCB기판(30)을 샤시(10)의 기판레일(40)에 끼워서 전단이 기판받침구(20)의 기판삽입홈(22)에 끼워지도록 함으로써, 메인 PCB기판(30)의 양측단은 양측 기판레일(40)에 지지되도록 하고 전단은 기판받침구(20)에 받쳐지도록 하여 메인 PCB기판(30)의 중간부가 자중에 의하여 처지지 않도록 한다.Thereafter, the main PCB board 30 is inserted into the board rail 40 of the chassis 10 so that the front end is inserted into the board inserting grooves 22 of the board support 20, thereby providing both sides of the main PCB board 30. Ends are supported by both substrate rails 40 and shears are supported by the substrate support holes 20 so that the intermediate part of the main PCB board 30 is not sag due to its own weight.

따라서 샤시(10)에 조립되는 메인 PCB기판(30)의 선단 중간부를 기판받침구(20)가 받쳐주어 메인 PCB기판(30)의 처짐을 방지하는 동시에 강도를 보강할 수가 있는 것이며, 또한 메인 PCB기판(30)의 선단 중간부를 기판받침구(20)의 기판삽입홈(22)에 삽입시키면 되므로 작업의 단순화를 도모할 수가 있는 것이다.Accordingly, the substrate support hole 20 supports the middle portion of the front end portion of the main PCB board 30 assembled to the chassis 10, thereby preventing the main PCB board 30 from sagging and reinforcing strength. Since the intermediate part of the front end of the board | substrate 30 needs only to be inserted into the board | substrate insertion groove | channel 22 of the board | substrate support opening 20, work can be simplified.

이와 같이 본 고안은 샤시에서 조립되는 메인 PCB기판의 선단 중간부를 받쳐주어 메인 PCB기판의 처짐을 방지하는 동시에 작업의 작업의 단순화를 도모할 수 있어 제품의 품질을 높일 수가 있는 것이다.As such, the present invention supports the middle part of the front end of the main PCB board assembled in the chassis, thereby preventing sagging of the main PCB board, and at the same time, simplifying the work, thereby improving the product quality.
