Abstract
Abstract A card edge connector to be surface-mounted on a circuit board having a plurality of conductors, which includes an insulation housing (100) having a base section (111) with a slot (112) for receiving a card edge on which a plurality of contact pads are provided; a plurality of bent-type contact elements arranged in the slot on at least one side (114) on which the connector is to be mounted on the circuit board; a plurality of movable arms (301) having contact points (307) for contact with the contact pads of the card; a plurality of fixing arms (303) having connection sections for connection to the conductors of the circuit boards and fixing sections (500) to be fixed to the insulation housing; a plurality of central arms (302) for connecting the movable arms and the fixing arms to form the substantially C-shaped, flexible contact elements; the connection sections of the fixing arms being at positions opposite to the central arms with respect to the fixing sections (500); and the contact points of the movable arms being at positions above the fixing sections or opposite to the central arms with respect to the fixing sections.
