will the utility model discloses a ZIF connector welds to PCB board (not shown in the figure). Before the FPC golden finger is inserted, the locking cover 3 is in an open state. When the FPC golden finger is inserted from the rear end (the end without the lock cover 3), the lock cover 3 is buckled, the lock cover rotating shaft 4 rotates 90 degrees, because the conductive terminal 2 is a conductive terminal made of elastic material, the lock cover rotating shaft 4 presses the front lower conductive terminal 22 downwards, and under the auxiliary action of the fixed shaft 6, the tail end 221 of the front lower conductive terminal and the tail end 241 of the rear lower conductive terminal are lifted simultaneously. Because the front upper conductive terminal ends 211 and the front lower conductive terminal ends 221 are staggered, the front upper conductive terminal ends 211 and the front lower conductive terminal ends 221 cannot contact with each other, and the front upper conductive terminal 21 and the front lower conductive terminal 22 cannot be conducted with each other.
