An electrical connector includes an insulating body having multiple receiving slots, and multiple first terminals and multiple second terminals respectively received in the receiving slots. Each first terminal has a first connecting portion, a first elastic arm bending and upward extending from the first connecting portion, and a first conducting arm bending and extending from the first connecting portion. Each second terminal has a second connecting portion, a second elastic arm bending and extending upward from the second connecting portion, and a second conducting arm bending and extending from the second connecting portion. A bent position between each of the first connecting portions and a corresponding one of the first elastic arms is higher than a bent position between each of the second connecting portions and a corresponding one of the second elastic arms.
