Patent ID: 10833450

Abstract:
A connection detecting member (30) is mounted on a support (20) of a lock arm (15) to be integrally resiliently displaceable, and relatively movable with respect to the support (20) between an initial position and a detection position. A resilient locking piece (32) of the connection detecting member (30) restricts a movement of the connection detecting member (30) to the detection position by contacting a front stop (19) of the lock arm (15) in a state where both housings (10, 50) are not connected or are connected incompletely. The first housing (10) is provided with a movement restricting portion (23) for restricting a movement of the connection detecting member (30) toward the detection position by contact with the connection detecting member (30) when the resilient locking piece (32) is displaced in a separating direction from the front stop (19) due to curved deformation of the lock arm (15).
