An electrical connector for use with flexible printed circuit (FPC) includes a casing having an interior chamber defined by two side walls and a bottom and having a top opening. The chamber has a plurality of slots formed therein for receiving conductive terminal members having a base from which two opposite arms extend. Each slot has a bottom section for receiving the base of the respective conductive terminal member and a side section defined by a recess formed on each of the side walls to receive therein one of the arms. Each of the arms has an inclined outer edge defining a gap with the side wall of the casing to allow the arms to be bent toward the side walls, forming an increased spacing between the arms for receiving therein the FPC. A shortened central arm, having sideward projected paws, is also provided on the base of the terminal members to be received within a central channel formed on the bottom of the chamber to retain the terminal member within the slot. A driver member having a plate to be inserted into the chamber with a sufficient gap formed between the plate and the side walls of the chamber for receiving and retaining therein the FPC is provided to be movable relative to the casing along an insertion direction to be inserted into the interior chamber.
