A matrix board-to-board connector includes a plurality of contacts and an insulating housing. Each contact has a retaining board, a first contacting portion defined at a bottom end of the retaining board, and a second contacting portion defined at an opposite end of the retaining board. The second contacting portion spirals up and defines a second pressing portion at the top end. A plurality of receiving cavities are formed in the insulating housing for receiving the contacts. The first contacting portion of the connector is connected to the lower circuit board by soldering. The second contacting portion elastically presses the upper circuit board to ensure a firm electrical connection between the upper circuit board and the lower circuit board.
