Description

모니터 회로기판의 지지부재(A member for supporting a PCB in monitor)A member for supporting a PCB in monitor

본 고안은 모니터의 회로기판을 받쳐주는 지지부재에 관한 것으로, 보다 상세하게는, 낙하테스트시, 모니터가 외부로부터 충격을 받아, 모니터에 내장된 회로기판이 파손되는 것을 방지한 모니터 회로기판의 지지부재에 관한 것이다.The present invention relates to a support member for supporting a circuit board of a monitor, and more particularly, to support a monitor circuit board which prevents the monitor from being damaged by an external shock during the drop test, thereby damaging the circuit board built into the monitor. It is about absence.

일반적으로, 모니터에 내장되는 회로기판에는 다수개의 전자부품을 비롯하여 여러가지 구조물이 실장이 되는 바, 이 구조물들 중에는 트랜스포머(transformer)나 방열체와 같이 부피가 크고 무거운 구조물이 있어, 이 중량의 구조물에 의해 회로기판이 아래로 휘어지게 하지 않도록 하는 것이 회로기판의 안정성을 위해 필요하다.In general, a circuit board embedded in a monitor includes various electronic components and various structures. Among these structures, there are bulky and heavy structures such as transformers and heat sinks. It is necessary for the stability of the circuit board to prevent the circuit board from bending downward.

특히, 모니터에 내장되는 회로기판은 모니터외함의 바닥면 전체에 걸쳐 장착될 정도로 넓은 면적을 차지하기 때문에, 회로기판이 휘어져 변형되지 않도록 회로기판의 하부면을 고루 받쳐 주는 것이 요구된다.In particular, since the circuit board embedded in the monitor occupies a large area enough to be mounted over the entire bottom surface of the monitor enclosure, it is required to support the lower surface of the circuit board evenly so that the circuit board is not bent and deformed.

따라서, 이러한 요구에 부응하여 당업계에서는, 회로기판의 하부면을 고루 받쳐 주기 위해, 회로기판을 감싸고 지지하는 지지프레임의 바닥면에 별도의 지지수단을 형성시켜 회로기판을 지지해주고 있기는 하나, 이 지지수단은 단순히 지지프레임의 일부를 변형시켜 형성시킨 것으로서, 모니터 제품이 낙하 테스트를 받거나 사용자의 부주의로 모니터 제품에 충격이 가해질 때 그 충격이 상기 지지프레임의 지지수단을 통해 직접 회로기판에 전달되어져 회로기판이 손상되는 문제점이 있었다.Therefore, in order to meet the demands in the art, in order to support the lower surface of the circuit board evenly, by supporting a circuit board by forming a separate support means on the bottom surface of the support frame surrounding and supporting the circuit board, This support means is formed by simply deforming a part of the support frame, and when the monitor product is subjected to the drop test or the user's inadvertent impact on the monitor product, the shock is transmitted directly to the circuit board through the support means of the support frame. There was a problem that the circuit board is damaged.

예컨대, 종래 회로기판을 지지하기 위한 지지수단이 도 3에 도시되어 있는 바, 본 도면에는 회로기판(50)의 양측부를 지지하는 한편 회로기판(50)이 착탈가능하게 안내홈이 형성된 가이드레일(51)과, 이 가이드레일(51)이 양측으로 부착되어 있고, 회로기판(50)의 하부를 받쳐 주도록 직각절곡된 지지편(52)이 바닥면에 다수개 형성된 상자형태의 지지프레임(53)이 나타나 있다.For example, a supporting means for supporting a conventional circuit board is shown in FIG. 3. In this figure, a guide rail having a guide groove formed thereon to support both sides of the circuit board 50 and to which the circuit board 50 is detachably attached ( 51 and the guide rail 51 are attached to both sides, and the support frame 53 is formed in the form of a box having a plurality of support pieces 52 which are bent at right angles to support the lower part of the circuit board 50. Is shown.

여기에서, 상기 지지편(52)은 도시된 바와 같이, 직각 절곡된 상단면이 회로기판(50)의 바닥면에 접촉된 채 스크류(54)를 매개로 하여 견고하게 연결되어 회로기판(50)이 휘어지지 않도록 회로기판(50)의 하부면을 받쳐 주고 있다.Here, as shown in the support piece 52, the perpendicularly bent top surface is firmly connected via the screw 54 while being in contact with the bottom surface of the circuit board 50, the circuit board 50 The lower surface of the circuit board 50 is supported so as not to be bent.

그런데, 상기한 종래의 기술 구성에 의하면, 상기 지지프레임(53)이 모니터외함(미도시함)의 내측바닥면에 고정되어 있기 때문에, 모니터 낙하테스트시 모니터외함에 가해진 충격은 지지프레임(53)에 그대로 전달되어지고, 이 지지프레임(53)에 가해진 충격은 다시 지지편(52)을 통해 회로기판(50)에 전달되기 때문에, 회로기판(50)이 소손되어, 회로기판(50)에 실장된 전자부품이 아울러 손상되거나, 회로기판(50)의 회로연결선이 단락되는 등 모니터 제품의 신뢰성 및 성능이 크게 저하되고 마는 문제점이 있었다.By the way, according to the prior art configuration, since the support frame 53 is fixed to the inner bottom surface of the monitor enclosure (not shown), the impact applied to the monitor enclosure during the monitor drop test is not supported by the support frame 53. Since the impact applied to the support frame 53 is transmitted to the circuit board 50 again through the support piece 52, the circuit board 50 is burned out and mounted on the circuit board 50. In addition, there is a problem that the reliability and performance of the monitor product are greatly reduced, such as damaged electronic components or short circuit connection lines of the circuit board 50.

이에 본 고안은 상기의 문제점을 해결하기 위해 안출된 것으로서, 모니터 낙하테스트시, 모니터외함에 가해진 충격이 회로기판에 전달되지 않게 하여 회로기판을 보호하는 한편, 회로기판이 안정되게 모니터에 내장될 수 있도록 하여 모니터 제품의 신뢰성을 확보할 수 있도록 한 모니터 회로기판의 지지부재를 제공함에 그 목적이 있다.Therefore, the present invention was devised to solve the above problems, and during the monitor drop test, the shock applied to the monitor enclosure is not transmitted to the circuit board to protect the circuit board, and the circuit board can be stably embedded in the monitor. The purpose of the present invention is to provide a support member of the monitor circuit board to ensure the reliability of the monitor product.

상기의 목적을 달성하기 위해 본 고안은, 모니터외함에 내장된 회로기판을 지지하는 지지프레임에 있어서, 상부면이 상기 회로기판의 하부면과 고정되는 제 1 지지판과, 하부면이 상기 회로기판을 지지하는 상기 지지프레임의 바닥면에 고정되는 제 2 지지판 및, 상기 제 1, 2 지지판의 사이에서 상측부가 상기 제 1 지지판의 하부면에 고정되고, 하측부가 상기 제 2 지지판의 상부면에 고정되는 지지스프링으로 이루어져 있다.In order to achieve the above object, the present invention provides a support frame for supporting a circuit board embedded in a monitor enclosure, the first support plate of which an upper surface is fixed to a lower surface of the circuit board, and a lower surface of the support frame. The second support plate is fixed to the bottom surface of the support frame to support, the upper side is fixed to the lower surface of the first support plate between the first, second support plate, the lower side is fixed to the upper surface of the second support plate It consists of a support spring.

따라서, 상기한 기술 구성에 의하면, 회로기판과 지지프레임의 사이에 충격 흡수가 용이한 스프링이 구비된 지지판이 설치되어지게 함으로써, 모니터 낙하 테스트시 모니터외함이 받는 충격이 직접적으로 회로기판에 전달되지 않도록 하여 모니터제품의 신뢰성이 유지되는 잇점이 있는 것이다.Therefore, according to the above technical configuration, a support plate with a spring which is easy to absorb shock is provided between the circuit board and the support frame, so that the impact of the monitor enclosure during the monitor drop test is not directly transmitted to the circuit board. In other words, the reliability of the monitor product is maintained.

여기에서, 상기 지지스프링(5)은 상기한 바와 같이 그 양측부가 제 1, 2 지지판(2,4)에 각각 고정되어 있는 바, 이때, 이 지지스프링(5)은 상기 지지판(2,4)에 각각 형성된 고정돌기(2a, 4a)에 의해 고정된다.Here, the support springs 5 are fixed to both side portions of the first and second support plates 2 and 4 as described above. In this case, the support springs 5 are the support plates 2 and 4. It is fixed by the fixing protrusions 2a and 4a respectively formed in the.

즉, 이 고정돌기(2a, 4a)는 상기 지지판(2,4)의 일측면에서 상단부위가 곡면으로 돌출되어 있도록 가공되어, 끼움홈(2b, 4b)이 형성되도록 이루어져, 이 끼움홈(2b, 4b)에 지지스프링(5)의 선단 양측부가 끼워져 고정되는 것이다.That is, the fixing protrusions 2a and 4a are processed so that the upper end portion protrudes from one side surface of the support plates 2 and 4 to the curved surface, so that the fitting grooves 2b and 4b are formed. , 4b) is fitted to both ends of the front end of the support spring (5).

따라서, 본 고안에 따른 지지부재는 한 쌍의 지지판(2, 4)이 지지스프링(5)을 매개로 서로 결합되는 구조로 이루어져 있다.Therefore, the support member according to the present invention has a structure in which a pair of support plates 2 and 4 are coupled to each other via a support spring 5.

이와같이 이루어진 지지부재에 의해 모니터의 회로기판(1)이 지지된 상태가 도 2에 도시되어 있는 바, 상기 제 1 지지판(2)이 회로기판(1)과 스크류체결되어 있는 한편, 상기 제 2 지지판(4)이 지지프레임(3)과 스크류체결되어 있는 상태가 나타나 있다.The state in which the circuit board 1 of the monitor is supported by the support member thus formed is shown in FIG. 2, wherein the first support plate 2 is screwed into the circuit board 1, and the second support plate is supported. The state in which (4) is screwed with the support frame 3 is shown.

이와같은 기술 구성에 의해, 모니터가 낙하테스트를 받게 되면, 모니터외함이 받는 충격은 그대로 상기 지지프레임(3)에 전달되어지나, 이 지지프레임(3)에 전달되어진 충격이 회로기판(1)에 전달되기 위해서는 상기 지지부재를 거쳐야 되므로, 이 충격이 상기 지지부재의 지지스프링(5)에 의해 감쇄되어질 수 있는 것이다.According to this technical configuration, when the monitor is subjected to the drop test, the shock received by the monitor enclosure is transmitted to the support frame 3 as it is, but the shock transmitted to the support frame 3 is transmitted to the circuit board 1.
