ABSTRACT:
In a card edge connector, rotating pins are formed on the inner surfaces of the side walls of a box-shaped outer housing, while cylindrical bearings are formed on the outer surfaces of the side walls of inner housings in which electrically conductive terminals are accommodated. The inner housings are swingably held with the rotating pins engaged with the cylindrical bearings. The cylindrical bearings have cut-outs in the cylindrical walls which are opened in the direction of insertion, so that, as the inner housings are pushed into the outer housing, the rotating pins are engaged with the cylindrical bearings through the cut-outs. The inner housings are urged by spring members in such a manner that the abutting parts of the terminals are moved away from terminals formed on the connecting end portion of a printed circuit board. When the connecting end portion of the printed circuit board starts to enter the outer housing is started, the connecting end portion gently touches the abutting parts of the terminals. When the connecting end portion is fully pushed into the outer housing, introducing cams, which are formed on a hood surrounding the connecting end portion, cause the inner housings to swing towards the connecting end portion, so that the terminals are positively pushed against the abutting parts.
