Abstract

An electric connector comprises a shield casing, an insulating body held in the shield casing, and a plurality of conductive terminals accommodated in the insulating body. The shield casing includes an upper surface, a lower surface, a left surface, and a right surface. The insulating body includes a main body part, and a plug joint part vertically disposed on the main body part. The shield casing also includes a back surface formed by backwards extending and bending the left and right surfaces. The back surface includes a holding surface shielding back end of the insulating body, and a shielding surface shielding the conductive terminals. The holding surface can effectively hold the insulating body, while the shielding surface can shield the conductive terminals to avoid electromagnetic disturbance.
