Abstract

The present invention discloses an electric connector of a plane grid array, which is used for electrically connecting a wafer die set and a circuit board. The present invention comprises an insulating basal body, a frame body which is framed on the circumferential side of the insulating basal body, a pressing cover which is movably pivoted on one end of the frame body, and a shifting rod which is arranged on the other end of the frame body, wherein the frame body comprises a bottom wall and four side walls, wherein slots are respectively arranged on the connecting points of two opposite side walls which are positioned between both ends of the pressing cover and the shifting rod, and the bottom wall. The pressing cover comprises a hollow main body board and side boards which extend from both sides of the hollow main body board to the insulating basal body, and slanting edges are arranged on both sides of each side board. When the electric connector is positioned on a closed position, the side boards of the pressing cover enter the slots of the frame body to limit the movement of the frame body corresponding to the pressing cover, and thus, accurate positioning of the wafer die set can be ensured. When a pressing rod rotates, two sides of the side boards are supported with corresponding two sides of the slots, which can prevent the wafer die set from being pressed excessively by the pressing cover or can prevent an insulating base from warping caused by pressing a boss when the boss is arranged on the insulating base.
