An electrical connector is used to be electrically connected to a chip module having multiple pins. The electrical connector includes a body to support the chip module upward and provided with multiple accommodating holes penetrating through an upper surface and a lower surface of the body, and multiple terminals correspondingly accommodated in the accommodating holes. Each accommodating hole has a blocking wall. Each terminal includes a base, two first arms bending forward from two opposite sides of the base and extending upward, and a second arm bending forwards from the base and extending downward. The two first arms have two clamping portions and two first guiding portions extending upward from the two clamping portions and away from each other. The blocking wall covers upper ends of the two first guiding portions. The second arm has a second guiding portion and an abutting portion extending downward from the second guiding portion.
