Abstract: A card edge connector includes a connection part and a position guider. The connection part includes a plurality of terminals disposed in parallel to electrically connect to contacts of a daughter board. The position guider disposed inside the connection part includes a guiding structure formed at two opposing lateral sides of the position guider. The guiding structure includes two slant surfaces extending respectively away from the left and right sides of the position guider. The slant surfaces are used to align the daughter board into a desired position to reduce a misalignment shift between the terminals of the connection part and the contacts of the daughter board.
