Patent ID: 8920187

Claim:
A connector, comprising: a housing main body be connected to a mating housing along a connecting direction; a lock arm projecting from the housing main body and being resiliently deformable in a deforming direction intersecting the connecting direction, a deformation space between the lock arm and the housing main body, the lock arm being formed with a lock projection projecting in the deforming direction from a side of the lock arm opposite the deformation space, the lock projection being configured to fit into a lock receiving portion of the mating housing at proper connection to hold the housing main body connected to the mating housing in a connected state, the lock arm including an accommodating recess that is open toward the deformation space and that is open on a rear surface of the lock projection; and a detector mounted on the housing main body for movement from an initial position to a detection position via a standby position and configured such that movement in a movement direction is restricted at the initial position by contact of the detector with the lock arm before the housing main body is connected to the mating housing, a movement restricted state at the initial position is released and the detector is kept at the standby position to face the accommodating recess along the movement direction when the housing main body is connected properly to the mating housing, and the detector reaches the detection position by a displacement operation in the movement direction from the standby position, whereby at part of the detector is inserted into the accommodating recess.
