Abstract
Abstract A connector for a sheet-like member includes a housing ( 1 ) providing an open mouth ( 110 ) for receiving the sheet-like member and a support surface ( 122 ); terminals ( 2, 3 ) arranged in the housing and each comprising a fulcrum portion ( 25, 35 ), a contact beam ( 22, 32 ) extending into the open mouth from the fulcrum portion and a pivot beam ( 24, 34 ) extending in opposite direction to the contact beam from the fulcrum portion; and an actuator ( 4 ) rotatable between an open and a closed positions. The actuator has shaft portions ( 41 ) pivotally engaging with the pivot beams and cam portions ( 42 ) between the shaft portions and rotatably supported on the support surface. The shaft portions will 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.
