The invention discloses a card edge connector, which comprises a lengthwise insulating body, a plurality of conductive terminals fixed on the insulating body and card locking pieces pivoted on the insulating body, wherein the insulating body is provided with two side walls extending along the lengthwise direction of the insulating body, a central slot positioned between the two side walls, and tower-shaped parts positioned at two ends of the central slot, the central slot is used for inserting a card module, the card locking pieces are respectively installed on the tower-shaped parts in a rotatable mode, each card locking piece is provided with a hook-shaped part for lifting the card module, the plurality of conductive terminals comprise two first conductive terminals located beside the tower-shaped parts, the hook-shaped part does not make contact with the first conductive terminals and does not enter the space between the two first conductive terminals in the process that the card locking piece rotates from a locking position for locking the card module to a releasing position for releasing the card module. Due to the design, the first conductive terminals are prevented from being damaged by the hook-shaped part.
