Zero insertion force contact and socket connector having the contact

A socket connector, used for connecting with a CPU (Central Processing Unit), comprising:

• a base defining a plurality of passageways;
• an insualtive cover attached onto the base and moveable between an open position and a closed position, the insulative cover defining a plurality of openings corresponding to the passageways;
• an actuating element for causing the movement of the insulative cover relative to the base;
• and
• a plurality of contacts partly received in the passageways and partly extending into the openings of the cover for connecting pins of the CPU, each contact comprising:
• a fixed portion;
• a soldering portion bending from a lower end of the fixed portion;
• an inversed U-shaped extension portion extending from an upper end of the fixed portion and facing to the soldering portion, the extension portion having a first arm portion connecting to the fixed portion, a second arm portion parallel to the first arm portion, and a connecting portion connecting with the first arm portion and the second arm portion;
• a first elastic portion connecting to the first arm portion;
• and
• a second elastic portion connecting to the second arm portion;
• wherein
• the first elastic portion and the second elastic portion laterally extend from a same side of the extension portion.
