The present application relates to the field of electric connector, particularly to an electric connector. The electric connector comprises a fastening body, a floating body and a plurality of electric terminals. The fastening body includes stop grooves, the floating body includes stop protrusions, and the electric terminals include resilient segments. The fastening body can overlap the outside of the floating body. The two stop protrusions are respectively located at the two sides of the floating body, and are respectively clutched in the two stop grooves when the fastening body 1 overlaps the outside of the floating body. The electric terminals are divided into two sets and are plugged into the fastening body and the floating body at the same time when the fastening body overlaps the outside of the floating body. The resilient segments are respectively located at one end of the electric terminals and are made by folding each electric terminal into a two layer structure.
