As described above in the embodiments, according to the connector with the disengagement mechanism of the present invention, when the actuator is operated in the fitting / disengaging direction, the tip portion is swung to the left and right, and the dismounting mechanism member side. Since the actuator moves only in parallel planes after being separated after being positioned at, the thin space can be configured. Further, the actuator and the base insulator slide with the base insulator with a very small force (a force due to the rotational force), and therefore wear is small.

Further, since the actuator drives the switch member fixed to the base insulator at a position where the actuator and the disengagement mechanism member are disengaged from each other, the switch can be operated before the mating connector is disengaged. it can.

Further, a protrusion protruding in the fitting direction is provided on one of the steps of the base insulator, and a shoulder protruding in the opposite direction is provided on the shoulder of the actuator engaging with the protrusion. The operation of the switch can be ensured, and the timing from the operation of the switch to the disconnection of the mating connector can be freely set.

Further, the tip of the actuator is divided into two parts in the thickness direction, and these are configured as slopes that selectively abut the separation mechanism member and the switch member and easily move to the next actuator posture. Therefore, the operation of the actuator can be ensured.
