본 발명은 인쇄회로기판에 관한 것으로서, 보다 상세하게는 인쇄회로기판의 측면 도금을 이용하여 복수의 인쇄회로기판을 결합시키는 인쇄회로기판의 연결 구조에 관한 것이다. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed circuit board, and more particularly, to a connection structure of a printed circuit board that couples a plurality of printed circuit boards by using side plating of the printed circuit board.

휴대용 단말기는 가정용 전화기와 달리 장소의 제약 없이 휴대하면서 통화할 수 있는 통신 기기이다. Unlike a home telephone, a portable terminal is a communication device that can carry and talk without restriction of place.

최근의 휴대용 단말기에서는 기본적인 기능인 위와 같은 통화 기능과 더불어서, 사진이나 동영상 촬영, 동영상 게임 및 방송 시청 등의 멀티미디어 기능이 접목되어 강화되어 가고 있는 추세이다.In recent years, in addition to the above call function, which is a basic function, the portable terminal has been strengthened by integrating multimedia functions such as photography, video recording, video game, and broadcast watching.

이러한 추세에 따라, 휴대용 단말기의 내부에 장착되는 인쇄회로기판(PCB)도 한 장만 사용하던 것이 여러 장이 사용되는 형태로 바뀌어 가고 있다.According to this trend, the use of only one printed circuit board (PCB) mounted inside the portable terminal is changing to a form in which several sheets are used.

이러한 여러 장의 인쇄회로기판을 연결하기 위해서는 인쇄회로기판에 별도의 커넥터를 납땜 방식으로 실장한 후에, 플렉시블 서킷 프린트(F-PC)이나 와이어(Wire)를 사용하여 각 인쇄회로기판을 연결해주어야 한다.In order to connect these multiple printed circuit boards, a separate connector is mounted on the printed circuit board by soldering, and then each printed circuit board is connected by using a flexible circuit print (F-PC) or a wire.

그러나, 이러한 방식에 따르면, 별도의 플렉시블 서킷 프린트나 와이어가 필요하고 인쇄회로기판에 커넥터를 납땜하여 실장하는 공정 등이 필요하게 되어, 제품 단가가 상승하고 제조 공정이 복잡해질 뿐만 아니라, 휴대용 단말기의 전체적인 부피도 커지게 되는 문제점이 있다.However, according to this method, a separate flexible circuit print or wire is required, and a process of soldering and mounting a connector on a printed circuit board is required, which increases the cost of the product and complicates the manufacturing process. There is a problem that the overall volume also increases.

상기와 같은 문제점을 해결하기 위하여 안출한 것으로서, 본 발명은 별도의 보조 부품없이도 복수의 인쇄회로기판들을 연결할 수 있는 인쇄회로기판의 연결 구조를 제공하는 것을 목적으로 한다. In order to solve the above problems, an object of the present invention is to provide a connection structure of a printed circuit board that can connect a plurality of printed circuit boards without a separate auxiliary component.

상기와 같은 목적을 달성하기 위하여, 본 발명의 일 측면에 따른 인쇄회로기판의 연결 구조는 인쇄회로기판에 일정 간격을 두고서 요입된 요입부와 그에 따 라 돌출한 연결돌기부로 이루어지는 연결부와; 상기 연결부의 연결돌기부의 측면에 도포된 도금층을 포함하여 이루어진다. In order to achieve the above object, a connection structure of a printed circuit board according to an aspect of the present invention is a connection portion consisting of a concave indentation and a convex projection projecting according to a predetermined distance to the printed circuit board; It comprises a plating layer applied to the side of the connecting projection of the connection portion.

여기서, 상기 연결부는 상기 인쇄회로기판의 일 측면부에 형성되는 것이 바람직하다.Here, the connection portion is preferably formed on one side portion of the printed circuit board.

본 발명의 다른 측면에 따른 인쇄회로기판의 조립체는 위와 같은 연결 구조를 가지는 인쇄회로기판과 그러한 구조를 가지는 다른 인쇄회로기판이 결합 시에 직각을 형성하여 이루어진다. The assembly of a printed circuit board according to another aspect of the present invention is formed by forming a right angle when the printed circuit board having the above connection structure and the other printed circuit board having such a structure are combined.

이하, 본 발명의 바람직한 실시예에 따른 인쇄회로기판의 연결 구조에 대하여 첨부한 도면을 참조하여 상세히 설명한다. Hereinafter, a connection structure of a printed circuit board according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 바람직한 일 실시예에 따른 인쇄회로기판의 연결 구조를 도시한 사시도이고, 도 2는 도 1의 구조를 가지는 인쇄회로기판들이 결합된 인쇄회로기판 조립체를 도시한 사시도이다.1 is a perspective view illustrating a connection structure of a printed circuit board according to an exemplary embodiment of the present invention, and FIG. 2 is a perspective view illustrating a printed circuit board assembly to which printed circuit boards having the structure of FIG. 1 are coupled.

도시한 바와 같이, 본 발명의 바람직한 일 실시예에 따른 인쇄회로기판의 연결 구조는 인쇄회로기판(1,2)의 일측에 일정한 간격을 두고서 요입된 요입부(13,33)와, 그러한 요입부(13,33)에 형성에 따라 상대적으로 돌출한 형태로 형성되는 연결돌기부(15,35)를 포함한다.As shown, the connection structure of the printed circuit board according to the preferred embodiment of the present invention is the recessed portion 13, 33 and the recessed portion at regular intervals on one side of the printed circuit board (1, 2), The connection protrusions 15 and 35 which are formed in a relatively protruding shape according to the formation at the 13 and 33 are included.

나아가, 이러한 연결돌기부(15,35)의 측면부에는 도금을 통하여 도금층(21,41)이 형성된다.Furthermore, plating layers 21 and 41 are formed on side surfaces of the connection protrusions 15 and 35 through plating.

이러한 구성에 따라, 이들 제1 및 제2 인쇄회로기판(1 및 2)를 결합하여 전기적으로 연결한 상태는 도 2와 같은 상태가 된다.According to this configuration, the state in which these first and second printed circuit boards 1 and 2 are coupled and electrically connected is in a state as shown in FIG.

다시 말하자면, 제1 인쇄회로기판(1)의 연결부(11)와 제2 인쇄회로기판(2)의 연결부(31)가 서로 교차하여 결합하는 것이다. In other words, the connecting portion 11 of the first printed circuit board 1 and the connecting portion 31 of the second printed circuit board 2 intersect with each other.

보다 구체적으로 기술하면, 제1 인쇄회로기판(1)의 연결부(11)의 연결돌기부(15)은 제2 인쇄회로기판(2)의 요입부(33)에 삽입되고, 제2 인쇄회로기판(2)의 연결부(31)의 연결돌기부(15)는 제1 인쇄회로기판(1)의 요입부(13)에 삽입된다.In more detail, the connecting protrusion 15 of the connecting portion 11 of the first printed circuit board 1 is inserted into the recess 33 of the second printed circuit board 2, and the second printed circuit board ( The connecting protrusion 15 of the connecting portion 31 of 2) is inserted into the recess 13 of the first printed circuit board 1.

이때, 제1 인쇄회로기판(1)의 연결돌기부(15)에 도포된 도금층(21)이 제2 인쇄회로기판(2)의 연결돌기부(35)에 도포된 도금층(41)과 접촉하여 인쇄회로기판들(1 및 2)가 전기적으로 연결된다.At this time, the plating layer 21 coated on the connecting protrusion 15 of the first printed circuit board 1 contacts the plating layer 41 coated on the connecting protrusion 35 of the second printed circuit board 2 to print the printed circuit. The substrates 1 and 2 are electrically connected.

그에 따라 형성된 인쇄회로기판 조립체는 결합된 두 개의 인쇄회로기판(1 및 2)이 대략 직각을 이루도록 결합되는 것이 바람직하다. 그에 따라 구적인 안정성이 확보되고, 전기적인 연결도 보다 안정적으로 이루어질 수 있기 때문이다. 그러나, 반드시 직각에 한정되는 것은 아님은 당업자라면 충분히 이해할 것이다.The printed circuit board assembly thus formed is preferably combined such that the two printed circuit boards 1 and 2 are joined at approximately right angles. As a result, quadrature stability can be secured and electrical connection can be made more stably. However, those skilled in the art will fully understand that they are not necessarily limited to the right angle.

이상과 같은 구성에 따르면, 복수의 인쇄회로기판의 사용이 날로 필수화되어 가는 현재의 휴대용 단말기에 있어서, 복수의 인쇄회로기판간의 연결에 필요한 F-PC나 케이블, 그리고 커넥터 등의 별도의 부품이 필요하지 않게 된다. 즉, 인쇄회로기판 자체에 형성된 톱니 형상의 연결부를 서로 결합해 주기만 하면, 그에 도포된 도금층에 의해 서로 간의 전기적인 연결이 이루어진다.According to the above-described configuration, in the current portable terminal where the use of a plurality of printed circuit boards becomes essential, separate components such as an F-PC, a cable, and a connector required for the connection between the plurality of printed circuit boards are required. You will not. That is, as long as the coupling portion of the saw-tooth formed on the printed circuit board itself is coupled to each other, the electrical connection between each other is made by the plating layer applied thereto.

그에 따라, 제조 원가가 감소하며, 커넥터를 인쇄회로기판에 실장하기 위한 납땜 공정 및 연결 공정 등이 보다 간단화되어 전체적인 제조 공정이 단순해지고, 휴대용 단말기의 전체 부피도 줄어들게 된다.As a result, manufacturing costs are reduced, and a soldering process and a connection process for mounting a connector on a printed circuit board are simplified, thereby simplifying the overall manufacturing process and reducing the overall volume of the portable terminal.

이상에서 설명한 바와 같이, 본 발명에 따른 인쇄회로기판의 연결 구조는 인쇄회로기판들을 전기적으로 연결하기 위한 별도의 보조 부품을 사용하지 않고서도 인쇄회로기판간에 직접적인 연결이 가능하여, 인쇄회로기판이 2 이상 사용되는 휴대용 단말기 등의 제조 단가를 낮추고 제조 공정을 단순화할 수 있는 등의 효과가 있다. As described above, the connection structure of the printed circuit board according to the present invention can be directly connected between the printed circuit boards without using a separate auxiliary component for electrically connecting the printed circuit boards, the printed circuit board 2 It is possible to reduce the manufacturing cost of the portable terminal and the like used above and to simplify the manufacturing process.
