ABSTRACT:
Connectors with a lever in which a pair of male and female connectors are mated with and disconnected from each other by rotating the lever. The lever having cam grooves and a lock portion is rotatably attached to the female connector. Cam pins are attached to the male connector. When both connectors are initially mated with each other, the cam pins engage with the cam grooves, and when the lever is rotated in a direction in which both connectors are mated with each other, the male connector moves toward the female connector. An elastic locking member is interposed between the lever and the female connector. An operational portion, reverse spring portions for urging the lever toward a direction opposite to that in which both connectors are mated, and lock spring portions to be engaged with the lock portion of the lever so as to maintain the lever in a locked position, are all integrally formed in the elastic locking member. The elastic locking member is elastically displaced by pressing the operational portion so as to disengage the lock portion of the lever from the lock spring portions of the elastic locking member. The reverse spring portions retain the lever in the released position. The locking member for locking the lever and the reverse spring portions for retaining the lever in a released position are integrally formed.
