Abstract:
1. A connector assembly comprising: a connector having a housing and a housing main body; a lock arm projecting from the housing main body, the lock arm being resiliently deformable in a deforming direction; a detector to be mounted on the housing main body movably in a moving direction from an initial position to a detection position, the detector including a main portion and a resilient arm that is extending from the main portion and being resiliently deformable in the deforming direction, a protrusion projecting from an upper surface of a front end of the resilient arm in the deforming direction, a movement restricting surface formed on a front end of the protrusion, the movement restricting surface extending transverse to the moving direction and substantially parallel to the deforming direction, and a contact portion projecting forward from a lower surface of the protrusion; and a mating connector having a mating housing connectable with the housing, the mating housing having a lock receiving portion engageable with the lock arm to lock the housings in the connected state, wherein the movement restricting surface of the resilient arm contacts the lock arm before the housing main body is connected to the main housing to restrict an insertion movement of the detector at the initial position and the contact portion of the resilient arm is held in contact with the lock arm in the deforming direction at the initial position to apply a pre-load to the lock arm; and the resilient arm is displaced from the initial position and enters a deformation space for the lock arm with the protrusion engaging a surface of the lock arm facing the deformation space and with a surface of the resilient arm opposite the protrusion substantially engaging the housing main body to restrict deformation of the lock arm when the housing main body is connected properly to the mating housing.
