Patent ID: 7147498

Claim:
An electrical connector adapted to be detachably fitted with a sheet-like member, comprising: an insulative housing providing an open mouth for being inserted with the sheet-like member at a front section thereof and a support surface at a rear section thereof; a plurality of terminals side-by-side arranged in the housing, and each comprising a fulcrum portion, a contact beam extending into the open mouth from the fulcrum portion and a pivot beam extending substantially in opposite direction to the contact beam from the fulcrum portion; and an actuator rotatable between an open position and a closed position, said actuator provided with shaft portions pivotally engaging with the pivot beams, and cam portions between the shaft portions and rotatably supported on the support surface of the housing, wherein the shaft portions and the cam portions are dimensioned so that the shaft portions can urge upwards the pivot beams to force the contact beams against the sheet-like member with aid of the fulcrum portions while the actuator is rotated from the open position to the closed position; wherein the cam portion is formed with a convex exterior surface having a first point contacting the support surface when the actuator is at the open position and a second point contacting the support surface when the actuator is at the closed position, and a dimension between the first point and the axis center of the shaft portion is smaller than a dimension between the second point and the axis center of the shaft portion; wherein the actuator has bosses respectively extending from longitudinal ends thereof and the housing has a to flange and a recess below the top flange accommodating a corresponding boss; wherein the support surface is an incontinuous upper surface of a bottom wall of the housing between every two adjacent terminals; wherein the pivot beam is formed with a yoke at the end thereof for accommodating the shaft portion, the yoke substantially of a U-shape comprising an upper and a lower parts.
