Abstract
Description
본 발명은 인쇄회로기판(printed circuit board;PCB)의 결합구조에 관한 것으로, 상세하게는 충격을 완화하는 인쇄회로기판의 결합구조에 관한 것이다.The present invention relates to a coupling structure of a printed circuit board (PCB), and more particularly to a coupling structure of a printed circuit board to mitigate impact.
일반적으로 인쇄회로기판의 결합구조는 인쇄회로기판상에 주어지는 외부의 충격을 흡수하고 완화하는 구조를 취한다.In general, the coupling structure of a printed circuit board has a structure that absorbs and mitigates an external impact given to the printed circuit board.
종래의 인쇄회로기판의 결합구조는 크게 스크류 고정형태, 고무지지 형태, 홀더 형태으로 나눌 수 있다.The coupling structure of a conventional printed circuit board can be largely divided into a screw fixing form, a rubber support form, and a holder form.
스크류 고정형태는, 도 1에 도시된 바와 같이, 쉴드바텀(15)으로부터 연장되어 인쇄회로기판(13)으로 연결되는 지지부(14)와 상기 지지부(14)의 상단에 배치되는 상기 인쇄회로기판(13)에 스크류(11)를 관통시켜 상기 지지부(14) 하단의 너트(27)와 결합되게 함으로써 상기 인쇄회로기판(13)을 고정시킨다.Screw fixing form, as shown in Figure 1, extending from the shield bottom 15 and connected to the printed circuit board 13 and the printed circuit board disposed on the upper end of the support (14) 13 to fix the printed circuit board 13 by penetrating the screw 11 through the screw 11 to be coupled with the nut 27 at the bottom of the support 14.
고무지지 형태는, 도 2에 도시된 바와 같이, 인쇄회로기판(13)과 쉴드바텀(17)사이에 고무(17)와 같은 진동감소부재를 이용한다.The rubber support type uses a vibration reducing member such as rubber 17 between the printed circuit board 13 and the shield bottom 17, as shown in FIG.
홀더 형태는, 도 3에 도시된 바와 같이, 쉴드바텀(15)에서 인쇄회로기판(13)으로 스냅(19)을 관통시켜 상기 인쇄회로기판(13)을 고정시킨다.In the holder form, as shown in FIG. 3, the printed circuit board 13 is fixed by penetrating the snap 19 from the shield bottom 15 to the printed circuit board 13.
스크류 고정형태는, 인쇄회로기판을 구비한 제품이 바닥면으로 떨어질 때 쉴드바텀에 충격이 전달되어 인쇄회로기판상에 스크류가 고정된 부분이 쉴드바텀과 충돌하여 인쇄회로기판의 파손을 가져올 수 있다.In the screw fixing type, when a product having a printed circuit board falls to the bottom, an impact is transmitted to the shield bottom, and a portion where the screw is fixed on the printed circuit board collides with the shield bottom, resulting in damage to the printed circuit board. .
고무지지 형태는, 스크류 고정 형태와 달리, 인쇄회로기판을 구비한 제품이 떨어질 때 쉴드바텀에 전달되는 충격에 대해선 보강이 가능하다. 다만, 제품이 바닥면과 반대방향으로 떨어질 때 인쇄회로기판에 전달되는 충격을 보강하고 구조를 유지해 줄 수 있는 수단이 없다.The rubber support form, unlike the screw fixing form, can be reinforced against the impact transmitted to the shield bottom when the product with the printed circuit board falls. However, there is no means to reinforce the impact transmitted to the printed circuit board and maintain the structure when the product falls in the opposite direction to the floor surface.
홀더 형태는, 장력(tension)을 가지는 스냅(snap)을 이용하여 상기 두 가지 형태의 결합구조보다는 완충효과가 우수하다. 다만, 인쇄회로기판이 파손되기 직전의 파괴력과 평형을 이루는 장력을 얻기에는 플라스틱의 탄성력은 한계가 있다.The holder type has better cushioning effect than the two types of coupling structure by using a snap having a tension. However, the elastic force of the plastic is limited in order to obtain a tension in equilibrium with the breaking force just before the printed circuit board is damaged.
본 발명은 상기한 바와 같은 종래 기술의 문제점을 개선하기 위한 것으로, 파괴력과 평형을 이루는 장력을 제공하고 인쇄회로기판의 상부 또는 하부로 전달되는 충격을 완화하여 인쇄회로기판의 파손을 방지하는 인쇄회로기판의 결합구조를 제공하는데 그 목적이 있다.The present invention is to improve the problems of the prior art as described above, to provide a tension in equilibrium with the breaking force and to mitigate the shock transmitted to the upper or lower portion of the printed circuit board to prevent breakage of the printed circuit board The purpose is to provide a bonding structure of the substrate.

도 4는 본 발명의 실시예를 구성하는 부품들을 나타낸다.4 shows the components that make up an embodiment of the invention.
도시된 바와 같이, 본 발명에 의한 결합구조는 스크류(11)와 상기 스크류(11)에 형성되는 제1와셔(23)와 상기 스크류(11)에 조립되는 스프링(21)과 상기 스프링(21)과 인쇄회로기판(13)과의 사이에 설치되는 제2와셔(25)와 상기 스크류(11)와 쉴드바텀(15)을 결합시키는 너트(37)를 구비한다.As shown, the coupling structure according to the present invention includes a screw 11 and a first washer 23 formed on the screw 11 and a spring 21 and the spring 21 assembled to the screw 11. And a second washer 25 installed between the printed circuit board 13 and the nut 37 for coupling the screw 11 and the shield bottom 15 to each other.
도 5를 참조하면, 먼저 스크류(11)의 머리부(31)에 제1와셔(23)를 결합시켜 별도의 조립작업이 필요없게 한다. 상기 머리부(31)에 연장되는 몸통부(33)에 스프링(21)이 조립된다. 상기 스크류(11)의 몸통부(33)는 상기 스프링(21)이 자유롭게 압축될 수 있도록 골이 없는 형태로 구성한다. 상기 몸통부(33)에서 상기 스프링(21)과 인쇄회로기판(13)이 접촉하는 부분에 제2와셔(25)를 삽입한다. 상기 제2와셔(25)는 중앙으로 상기 스크류(11)가 관통하도록 한다. 상기 제2와셔(25)는 중앙에 십자형의 슬릿구조를 형성한다.Referring to FIG. 5, first, the first washer 23 is coupled to the head 31 of the screw 11 so that no separate assembly work is required. A spring 21 is assembled to the body portion 33 extending to the head 31. Body portion 33 of the screw 11 is configured in the form without a bone so that the spring 21 can be freely compressed. The second washer 25 is inserted into a portion of the body portion 33 where the spring 21 and the printed circuit board 13 are in contact with each other. The second washer 25 allows the screw 11 to penetrate to the center. The second washer 25 forms a cross slit structure in the center.
본 발명의 실시예의 조립순서는 먼저 제 1 와셔가 형성된 스크류에 스프링이조립되고 상기 스프링과 인쇄회로기판사이에 제 2 와셔를 더 구비하여 어셈블리를 이룬다. 상기 어셈블리를 상기 인쇄회로기판에 관통시켜 쉴드바텀과 너트로 결합하여 본 발명의 실시예를 완성한다.The assembly sequence of the embodiment of the present invention is a spring is first assembled to the screw on which the first washer is formed and further comprises a second washer between the spring and the printed circuit board to form an assembly. The assembly is penetrated by the printed circuit board and coupled with a shield bottom and a nut to complete an embodiment of the present invention.
본 발명의 기본 결합구조의 형태는 스크류 고정형태이다. 본 발명에 의한 구조는 바닥에 대한 충격은 열어두고 상부에 대한 충격 변위량을 완충할 수 있다. 스프링의 상하에 와셔를 배치하여 스크류의 고정을 돕고 인쇄회로기판과의 접촉면을 유지하여 충격을 완화한다. 이런 구조는 조립은 용이하나 조립 후 상기 제2와셔(25)가 빠지는 것을 방지하여 조립된 상태를 유지할 수 있도록 한다.The form of the basic coupling structure of the present invention is a screw fixing form. The structure according to the present invention can buffer the impact displacement on the top while leaving the impact on the bottom open. The washer is placed on the top and bottom of the spring to help fix the screw and to keep the contact surface with the printed circuit board to alleviate the impact. This structure is easy to assemble, but after the assembly to prevent the second washer 25 to fall out to maintain the assembled state.
상기한 설명에서 많은 사항이 구체적으로 기재되어 있으나, 그들은 발명의 범위를 한정하는 것이라기보다, 바람직한 실시예의 예시로서 해석되어야 한다.While many details are set forth in the foregoing description, they should be construed as illustrative of preferred embodiments, rather than to limit the scope of the invention.
상술한 바와 같이 본 발명의 장점은 스프링과 같은 탄성부재를 채용하여 충격에 대한 완충시간을 갖게 하고 충격을 소멸시켜 인쇄회로기판의 파손을 방지한다.As described above, an advantage of the present invention is to adopt an elastic member such as a spring to provide a shock-absorbing time and to extinguish the impact to prevent breakage of the printed circuit board.
