Patent ID: 7524204

Claim:
An electric connector comprising: a contact having a fixed beam and a movable beam which extend in an insertion direction of a connection object; an insulating housing which holds the contact internally; and an actuator which is positioned on an opposite side from insertion of the connection object and elastically deforms the contact so as to bring the contact in contact with the connection object, wherein the movable beam of the contact is swingably supported via a coupling spring portion joining the movable beam and the fixed beam integrally, wherein the coupling spring portion has a shape of extending in a curved manner from a joined portion thereof with the fixed beam toward a connector rear end which corresponds to a direction in which the connection object is inserted so that an insertion space for the connection object is obtained, wherein the fixed beam extends integrally from (1) a connector rear end having a connecting terminal portion connected to a printed circuit board by soldering to (2) a connector front end having a contact portion which contacts the connection object, wherein the fixed beam is attached to a bottom portion of the insulating housing such that (1) the connector rear end is provided in a fixed state from the connecting terminal portion to a joined portion of the coupling spring portion, and (2) the connector front end is provided so as to warp upwardly from the joined portion of the coupling spring to the contact portion thereby creating a space between the contact portion and the bottom portion of the insulating housing, and wherein a curved shape of the coupling spring portion is formed in an approximately crank shape or an approximately V shape.
