An electrical connector for electrically connecting a central processing unit (CPU) to a printed circuit board (PCB) comprises an insulating housing having a plurality of passageways extending from a top surface to a bottom surface and a plurality of terminals received in the corresponding passageways. Each terminal includes a horizontal base portion with a solder ball attached thereto, a pair of upper legs extending upwardly from one end of the base portion and a pair of lower legs extending downwardly from the other end of the base portion. The upper legs abut against the top surface of the insulating housing and the lower legs abut against the bottom surface of the insulating housing for retaining the terminals in the insulating housing.
