An electrical connector includes an insulating body with multiple accommodating slots, and multiple terminals accommodated in the accommodating slots. Each terminal has an elastic arm, a floating contact portion and a conducting portion. The elastic arm and the floating contact portion are provided at an interval. One end of the elastic arm is connected with the floating contact portion through an insulating block. When each terminal is mated with a first electronic component and a second electronic component, the conducting portion is electrically connected to the first electronic component, the floating contact portion is electrically connected to the second electronic component, the elastic arm provides an elastic force such that the floating contact portion moves downward, and the floating contact portion and the conducting portion are directly electrically connected.
