Description
본 고안은 기판과 기판을 연결하는데 쓰이는 커넥터에 관한 것으로, 특히 두께가 얇으면서도 결합커넥터와 쉽고 확실하게 연결할 수 있는 기판-기판 커넥터에관한 것이다.The present invention relates to a connector used to connect a board to a board, and more particularly, to a board-to-board connector that can be easily and securely connected to a mating connector while being thin.
전자장치는 점차 부피가 작아지는 경향이 있고, 그에 따라 그에 쓰이는 부품도 점차 작아지는 경향이 있다. 그렇지만 부피가 작은 부품을 제조하고 정밀하게 조립하기 위해서는 많은 어려움이 따르게 된다. 그리고, 부피가 작은 기판과 기판을 연결하는 커넥터(이하 기판-기판 커넥터라 함)는 일반적으로 결합커넥터와 결합되기 위해 인쇄회로기판(PCB)에 조립되게 되는바, 이 경우 기판-기판 커넥터와 결합커넥터 사이에 이탈이 일어나지 않아야 한다. 이러한 이탈이 방지되도록 하기 위한 종래의 기술로는, 접속단자에 잠금부가 갖춰지도록 된 것이 미국특허 제5975916호에 기재된 것을 들 수 있다.Electronic devices tend to become smaller in volume, and the parts used therein also tend to become smaller. Nevertheless, it is difficult to manufacture small parts and assemble them precisely. In addition, a connector connecting a board with a bulky board (hereinafter, referred to as a board-to-board connector) is generally assembled to a printed circuit board (PCB) to be combined with a coupling connector. There should be no separation between the connectors. As a conventional technique for preventing such detachment, the one described in US Pat.
그러나, 이와 같은 종래의 기판-기판 커넥터는 다음과 같은 결점을 갖게 되는바, 즉 종래의 기판-기판 커넥터는 도 6에서 볼 수 있듯이 복수의 역U자 형상의 접속단자(50)를 갖도록 되어 있어서, 이들 접속단자(50)를 제조하기 위해서는 금속스트립을 찍어 재단하고서 접어야 한다. 그리고, 각 접속단자(50)는 충돌부(53)와 이 충돌부(53)로부터 연장되어 굽혀진 접촉부(51) 및 이 접촉부(51)의 한쪽 끝 부분에 해당하는 얇은 두께의 단부(52)로 구성되어 있다. 이들 접속단자(50)는 크기가 대단히 작고 또 그 단부(52)가 결합커넥터(도시되지 않음)와 견고하게 잠겨져 고정되도록 하기 위해서는 두께가 너무 얇도록 되어 있다.However, such a conventional board-to-board connector has the following drawbacks, i.e., the conventional board-to-board connector has a plurality of inverted U-shaped connection terminals 50 as shown in FIG. In order to manufacture these connection terminals 50, a metal strip must be cut and folded. Each connecting terminal 50 has a collision portion 53, a contact portion 51 extending from the collision portion 53 and bent, and an end portion 52 having a thin thickness corresponding to one end portion of the contact portion 51. Consists of These connection terminals 50 are extremely small in size and are made too thin in order that their ends 52 are securely locked and fixed with the mating connector (not shown).
더구나, 상기 접촉부(51)는 가요성을 갖도록 충돌부(53)로부터 간극을 갖도록 떨어져야 하므로, 상기 접촉부(51)와 충돌부(53) 사이의 거리를 줄일 수가 없게 된다. 또한, 접속단자(50)의 형상이 역U자 형상으로 되어 있어서 높이를 줄일 수도 없다. 이상과 같은 형상의 특징으로 말미암아 접속단자(50)의 크기를 작게 할 수가 없다는 것이 결점으로 되고 있다.In addition, since the contact portion 51 must be spaced apart from the impact portion 53 so as to have flexibility, the distance between the contact portion 51 and the impact portion 53 cannot be reduced. In addition, since the shape of the connection terminal 50 becomes an inverted U-shape, height cannot be reduced. It is a drawback that the size of the connection terminal 50 cannot be made small by the characteristic of the shape mentioned above.
본 고안의 목적은, 결합커넥터의 결합단자에 확실하게 결합될 수 있는 크기가 작은 기판-기판 커넥터를 제공함에 있다.It is an object of the present invention to provide a small board-to-board connector that can be securely coupled to a coupling terminal of a coupling connector.
