Electrical contact for LGA socket connector

A socket connector for connecting a CPU to a PCB, comprising:

• an insulative housing comprising:
• a base member defining a plurality of spaced receiving cavities and mounting slits communicating with corresponding receiving cavities;
• and
• a frame assembling around the base member;
• and
• a plurality of electrical contacts each comprising:
• a retention plate received in a corresponding mounting slit;
• and
• a spring arm received in a corresponding receiving cavity and including a first curved arm extending downwards and slantsways from the retention plate, a second curved arm extending upwardly and slantways from a distal end of the first curved arm and face opposite to the first curve arm, and a third arm extending from a distal end of the second curved arm toward the retention plate;
• wherein
• the third curved arm has a top contacting end for contacting the CPU and the first curved arm has a bottom contacting end for contacting the PCB;
• wherein the spring arm further comprises a thinner connecting arm punched from the retention plate and connecting the first curved arm to retention plate;
• wherein the frame forms a plurality of resilient arms on adjacent sides thereof for securing a true position of the CPU;
• wherein the base member forms a plurality of semi-circular circles and the frame defines a plurality of indentations for receiving corresponding semi-circular circles.
