Abstract: The present invention is to provide a board to board connector, which comprises an insulative housing, a plurality of electrical terminals and a pair of fastening members. The insulative housing has a plurality of terminal chambers which pass from the bottom face through the top face of the base portion thereof for accommodating the electrical terminals. Each terminal includes a contact portion, a fixing portion and a two-way multi-layer U-shaped spring portion connected therebetween. The spring portion has perfect elasticity, and the contact portion is formed with a stopping portion at the end connecting the spring portion, and on the other end forming an abutting portion, which could match with the insulative housing effectively. The fastening members are disposed in the wide slots on two side convex portions of the insulative housing to connect with the PCB to achieve signal transmission.
