A socket connector includes an insulating body having a base body and a holding body extending upward from a front of the base body. The holding body defines a terminal fillister spread to the base body. A plurality of openings is opened in a front face of the holding body and communicates with the terminal fillister. A terminal group molding in the terminal fillister of the insulating body has a plurality of elastic touching arms stretching outside the insulating body, and a plurality of contact slices exposed through the openings respectively. A magnetic body defines a window. The magnetic body is mounted to a front of the insulating body with the window facing the openings to further expose the contact slices therethrough. The terminal group has a ground terminal elastically projecting forward out of the insulating body to electrically abut against a rear face of the magnetic body.
