Electrical connector with lever

An electrical connector comprising:

• a base having an opening to which a distal end of a flexible printed circuit board is inserted formed on a front surface, a plurality of insertion holes passing from the front surface to a rear surface adjacently arranged at a predetermined pitch, and a position regulating surface of one step lower formed at an edge of an upper surface on the rear surface side;
• a connection terminal to be inserted to the insertion hole from the rear surface side, the connection terminal being arranged in a projecting manner with a substantially T-shaped operation piece having, at a first end, a movable contacting point that pressure-contacts a connecting portion adjacently arranged at the distal end of the flexible printed circuit board;
• and
• an operation lever having an upper surface of the connection terminal as a rotation supporting point, including a cam portion for driving an operation receiving portion positioned at a second end of the operation piece, and being formed with a contact portion that rides on a position regulating surface of the base at an edge of the upper surface on the front surface side;
• wherein when the operation lever is rotated for opening, the contact portion of the operation lever rides on the position regulating surface of the base before the upper surface of the operation lever contacts the edge of the upper surface on the rear surface side of the base, so that the operation lever is lifted upward.
