Abstract
In an electrical connector mounted onto a printed board for electrically connecting contact pads of LSI circuit and contact pads of the printed board, a plurality of generally U-shaped contacts are held in contact holes in an insulator of the connector. Each contact has a bridge portion connecting both legs of "U" and projecting out of the contact hole above the insulator, and an extension portion obliquely extending from one end of a leg of the "U" and protruding the contact hole below the insulator. The projecting portion of the bridge portion has a contact point for the contact pad of the LSI circuit and the extension portion has a contact point at extending end portion for a contact point of the printed board. Thus, the contact pad of the LSI circuit and the contact pad of the printed board are connected through a relatively short signal path defined by the leg and the extension portion of the contact which is slightly larger than the thickness of the insulator, so that the reliability of the electrical connection is graded up for a high frequency band. Further, the contact points slide on the contact pads, respectively, when the connector with the lSI circuit is mounted on the…
