41, one end 53 of the actuator 40.
The contact surface 55 of the actuator 40 provided on the opposite side
It is in contact with the detachment mechanism member. Such a state is shown in FIG.
And FIG. Due to such deflection of the actuator 50, the one end 53 of the actuator 50 and the detachment mechanism member are engaged with or disengaged from the lever 60.

In the state shown in FIG. 17, the contact surface 55 of the actuator 50 is connected to the first cam surface 24d of the cam member 24.
Is in contact with The engagement piece 72 is pushed in the fitting direction by the front end face of the mating connector 120 on the fitting side, and the plate 70 is located at the back of one side of the base insulator 20. At this time, since the locking piece 61 has also moved to the back with the plate 70, the receiving plate 62 has moved in the detaching direction about the shaft hole 63 as an axis.

The first and second shoulders 51 and 52 of the actuator 50 are mutually engaged with the engagement projection 122 and the fourth step 114, and on their left side (left side of the paper), substantially Since the downward force is received from the spring member 130, the actuator 50 receives a force to turn to the left on the paper surface, and the one end 53 of the actuator 50 is moved to the base insulator 2.
0 Eject button mounting part 20g Right mounting wall 2
It hits the 0x plane and is balanced. Further, when the eject button 40 is slightly pressed from this state, the state shown in FIG. 18 is obtained.

In the state shown in FIG. 18, the distal end surface 54 of the actuator 50 presses the second cam surface 24d of the base insulator 20. At this time, the actuator 50
At one end 53, a force almost directly above is received, and at a slightly lower left portion of the drawing, a force substantially lower than the spring member 130 is received. Therefore, the actuator 50 receives a force to turn to the left of the drawing. I have. When the eject button 40 is further pressed from here, as shown in FIG. 19, the first shoulder portion 51 is disengaged from the engagement projection 122, the actuator 50 turns to the left on the paper, and the tip end surface 54 also moves to the left. The fourth cam surface 2

When the force applied to the eject button 40 starts to be loosened, the actuator 50 moves in the detaching direction together with the eject button 40, and only the second shoulder 52 is in the fourth position of the eject button mounting portion 20g. Step 11
4 is abutted in the detaching direction, and further movement in the detaching direction is prevented. Further, when the pressing on the eject button 40 is completely released, the force directly above the one end 53 of the actuator 50 disappears as shown in FIG.
The second shoulder 52 receives an upward force from the fourth step 114.

The force received from the spring member 130 is on the right (right side of the paper) of the second shoulder 52 and is a substantially downward force. Become. Here, the one end 53 of the actuator 50 is tilted to the right of the paper surface, and is located at a position where the receiving plate portion 62 of the lever 60 and the contact surface 55 of the actuator 50 face each other.

When the ejection button 40 starts to be pressed again, the state shown in FIG. 21 is established, and the curved surface portion 62a of the lever 60 is pushed by the contact surface 55, and the lever 60 rotates to the right of the paper surface. It comes off from the receiving plate part 62. At this time, the plate 70 moves in the detaching direction from the back of the base insulator 20 by the rotation of the lever 60, and the engaging piece 72 of the plate 70 is
The user starts to pull out the tip end surface 20 in the detaching direction. At this time,
In the actuator 50, the contact portion 53 is provided with the eject button 4
0, and tries to turn to the right on the paper to receive a substantially downward force from the spring member 130, and the second shoulder 5
1 gets over the engaging projection 122.

When the pressing force in the fitting direction to the eject button 40 is released, the first shoulder 51 on the right side of the actuator 50 receives a force from right below, contrary to FIGS. An attempt is made to rotate and the state shown in FIG. 22 is obtained. In this state, since the mating connector 120 has been discharged, the mating connector 120 can be taken out by hand. When the mating connector 120 is fitted again from this state, the state returns to the fitted state in FIG.

Further, since the actuator drives the switch member fixed to the base insulator at the position where the engagement between the actuator and the detachment mechanism member is released, the switch can be operated before detaching the mating connector. it can.

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

The distal end portion of the actuator is divided into two parts in the thickness direction, and these are constituted by inclined surfaces which selectively contact the detachment mechanism member and the switch member and are easy to shift to the next actuator posture. Therefore, the operation of the actuator can be ensured.
