[Prior art]
Due to the rapid development of the knotbook, its size is gradually becoming smaller, so the signal transmission device will be correspondingly smaller, lighter and more portable. It is. In the first place, the electronic card connectors in the early knotbooks were individually mounted on the circuit board, and when two or more electronic card connectors were applied to the same computer, they adopted a parallel-parallel structure. However, the number of components in the system has become too large, and the required space has been increased, which has greatly contributed to the miniaturization of the knotbook.
[0003]
Thereafter, a stacked electronic card connector was devised, for example, an electrical connector as disclosed in US Pat. No. 5,324,204. The electrical connector simply overlaps the first connector and the second connector, and switches signal transmission between the electronic card and the system by means of both rows of terminals, in which case the space required in the horizontal direction is reduced. However, the overall height of the electrical connector has been increased, and the signal transmission through both rows of terminals has increased the difficulty in mounting the terminals or increased the manufacturing cost, despite the fact that the number of members could not be reduced. is there. Therefore, how to design a stack-type electronic card connector that can reduce the number of members and save space is a problem to be overcome.
