An electrical connector used for carrying a chip module includes an insulating body having terminals arranged in the insulating body and used for contacting the chip module, a carrying member used for carrying the chip module to the insulating body, a pressing plate used for pressing the carrying member or the chip module, and a positioning member pivoted to the carrying member through a pivoting device. The pivoting device includes a pivoting shaft and at least one elastic portion. The elastic portion includes a first elastic section and at least two limiting portions being elastic and enclosing a pivoting space. The pivoting shaft is pivoted to the pivoting space. When the electrical connector is opened, the first elastic section springs back to remove the chip module from the insulating body without damaging the terminals, so as to align and contact the chip module with the terminals without tool.
