BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an electrical connector for use with a CPU (Central Processing Unit), and particularly to the electrical contact for use within the electrical connector.

2. Description of Related Arts

U.S. Pat. No. 7,878,818 discloses an electrical connector with a plurality of contacts. Each contact has a planar main body with a pair of retaining bars on two lateral sides for engagement with the housing, and a pair of resilient contacting arms extending from opposite upper and lower ends for contacting the CPU and the PCB (Printed Circuit Board). Anyhow, the structure of the contact may not fit for high frequency transmission.

Therefore, it is desired to provide an electrical connector with corresponding contacts for high speed and high frequency transmission.

SUMMARY OF THE INVENTION

To achieve the above object, an electrical connector includes an insulative housing with a plurality of passageways extending therethrough in the vertical direction. A plurality of contacts are disposed within the corresponding passageways, 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 in a coplanar manner. In each contacting arm, the width of the oblique section is larger than the vertical section while being essentially same with a distance defined by the pair of extension arms so as to achieve the impedance matching for high frequency transmission.

Other advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
