Terminal for board to board connector

An electrical connector comprises a dielectric housing which defines two rows of chambers being in communication with a pair of slots and defined by a number of dividers, and a number of terminals received in the chambers. Each terminal includes a base, a soldering tail, a spring beam, a curved beam continuing the spring beam and a contacting beam. The base of each terminal has a number of embossments interferentially engaging with adjacent dividers for preventing the base from buckling during assembly and a number of barbs for securing the terminal by interferentially mating with the housing. The base further has a pair of recesses beside the spring beam for improving the compliance of the contacting beam in mating with a complementary connector. A neck is provided between the base and the soldering tail such that ensuring an even soldering of the soldering tails to a circuit board.
