Patent ID: 7011536

Claim:
A connector, comprising: a housing connectable with a mating housing along a connecting direction, the mating housing being formed with at least one follower pin; a movable member having a front side facing in the connecting direction and an opposite rear side facing away from the connecting direction, the movable member being formed with at least one cam groove having a starting end on the front side of the movable member and a terminus end between the front and rear sides of the movable member, the movable member being mounted to the housing for movement in an operating direction intersecting the connecting direction of the housings, the cam groove being engageable with the follower pin on the mating housing and being formed such that the follower pin is displaced from the starting end to the terminus end of the cam groove as the movable member is moved in the operating direction for moving the housings to a properly connected state; and the cam groove further comprises a rearwardly inclined portion extending from the starting end towards the rear side of the movable member at an acute angle to both the operating direction and the connecting direction and a forwardly inclined returning portion extending from the rearwardly inclined portion back towards the front side of the movable member at an acute angle of inclination to both the operating direction and the connecting direction and continuing to the terminus end of the cam groove to displace the housings in separating directions as the follower pin is moved toward the terminus end in the cam groove; wherein the cam groove comprises a peak between the inclined portion and the returning portion, the peak defining a portion of the cam groove closest to the rear side of the movable member.
