An electrical connector, configured to be electrically connected to a mating plug, the mating plug being provided with a substrate and a plurality of conducting portions protruding downward from the substrate, and the electrical connector comprising:

• an insulating body;
• a plurality of terminals, respectively accommodated in the insulating body, wherein each of the terminals is provided with a contact portion;
• a cover, covering the insulating body in a front-rear sliding manner and having a hollow portion to accommodate the substrate, wherein the hollow portion has a virtual center line extending in a left-right direction, the cover is provided with a pulling portion to abut the substrate forward, and the pulling portion is located in front of the virtual center line;
• and
• a driving member, provided with a driving portion located in front of the hollow portion,
• wherein after the substrate of the mating plug is mounted downward into the hollow portion, the driving portion drives the cover to move horizontally forward relative to the insulating body, and the pulling portion pulls the substrate forward, such that the conducting portions move forward to be in contact with the contact portions of the terminals.
