Abstract

The invention provides an ultra-thin easy-lock and easy-unlock connector which can connect a printed circuit board and a flexible flat cable with a notch. The ultra-thin easy-locking and easy-unlocking connector includes a terminal, a shell, an insulator and a plurality of locking members. The shell is provided with a plurality of shrapnel to correspond to the locking members. Each of these locking members provides a hook arm and a hook part. When the hook part is subjected to a first external force generated by the flexible cable, the hook arm rotates at an angle in a first direction until the notch corresponds to the hook part, so that the hook part receives the elastic force of each of the shrapnel so that the hook arm faces a first direction. Rotating in second direction allows the hook to snap into the notch; in addition, the hook is subjected to a second external force generated by the flexible cable to cause the hook arm to rotate in the first direction to allow the notch to slide out of the hook to unlock.
