A high-speed data transmitting electric connector with dual shield functions comprises a plug connector and a socket connector which is in butt joint with the plug connector, wherein the socket connector utilizes a dual shield structure, namely respectively arranging ground shield plates between rows and columns of each differential contact element pair, arrangement of the shield plate rows and columns is realized by laminates in the socket connector, shield plates among rows and columns are connected by interference forced fit of stitches and flexible contact at the transition end or direct forced fit, thereby realizing reliable electric connection, and achieving the purposes of controlling impedance of each differential pair, reducing mutual interference of each differential pair, and realizing high-speed data transmission.
