A plurality of contacts are disposed within the corresponding passageways of the housing of the electrical connector, respectively. Each contact includes a main body extending in a vertical plane with two pairs of fixing sections on two opposite lateral sides to form an X-like shape, and a pair of resilient contacting arms extending from opposite upper and lower ends of the main body for mating with the CPU and PCB. A pair of extension arms extend from the waist section of the main body in a direction perpendicular to the vertical plane. The contacting arm includes a vertical section coplanar with the main body, an oblique section extending from an upper end of the vertical section with a bulged and narrowed contacting section at the free end. Each pair of fixing sections are located by two sides of the vertical section of the corresponding contacting arm.
