A socket connector includes an insulating body having a base portion and a holding portion extending upward from a front of the base portion. The holding portion defines a terminal fillister spread to the base portion. A plurality of openings is opened in a front face of the holding portion and communicates with the terminal fillister. A terminal group is molded in the terminal fillister of the insulating body. The terminal group 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 is curved from a magnetic metal board and defines a window. The magnetic body is mounted around the holding portion with the window facing the openings of the insulating housing to further expose the contact slices therethrough. The terminal group further electrically contacts with the magnetic body.
