Electrical connector having terminals with reliable retention protrusions

An electrical connector for electrically connecting an electronic package with a circuit substrate, the electrical connector comprising:

• an insulative housing defining a plurality of passageways therein, each of the passageways comprising a retention space bounded by a first wall, a pair of side walls, and a pair of second walls;
• and
• a plurality of terminals received in the passageways, each of the terminals comprising a retention portion and a plurality of retention protrusions extending from the retention portion, the retention portion comprising a first main face, a second main face, and a pair of side faces, each of the protrusions comprising a first interference portion and a second interference portion;
• wherein each of the protrusions of each of the terminals protrudes beyond either the first main face or the second main face and beyond a respective side face of the retention portion, the first interference portions of the protrusions interferentially engage with the side walls of a corresponding passageway, and the second interference portions of the protrusions interferentially engage with any one or more of the first and second walls of the corresponding passageway respectively, whereby the terminal can be securely received in the corresponding passageway.
