Socket connector with anti-rotation device

A socket connector comprising:

• a base defining a first main body and a first head portion;
• a plurality of passageways defined in the first main body;
• a plurality of terminals disposed in the corresponding passageways, respectively;
• a cover mounted upon the base and moveable along a front-to-back direction relative to the base, and defining a second main body and a second head portion in alignment with the first main body and the first head portion, respectively;
• a plurality of through holes formed in the second main body in alignment with the corresponding passageways, respectively;
• complementary interengaging means formed between the first head portion and the second head portion to prevent the second head portion from laterally moving relative to the first head portion;
• and
• an actuator disposed in both said first head portion and said second head portion and being rotatable about a vertical axis to drive the cover to move in said front-to-back direction relative to the base.
