Connector with positive locking features

A connector comprising first and second connector housings that are connectable with each other, the first connector housing comprising:

• a lock arm substantially elastically deformable between a locking position where the second connector housing is locked and an unlocking position where the second connector housings is unlocked,
• a slider movable between a displacement restricting position where a displacement of the lock arm in the locking position toward the unlocking position is restricted and a displacement permitting position where the displacement of the lock arm toward the unlocking position is permitted, the slider further being movable from the displacement permitting position to a forcible displacement position,
• the connector housings being locked into each other by displacing the lock arm to the locking position to lock the second connector housing and moving the slider to the displacement restricting position, the connector housings being released from the locked state to separate from each other by moving the slider to the displacement permitting position and displacing the lock arm to the unlocking position, and
• a forcible displacing member comprising a pushing portion formed on the slider and a pushable portion formed on the lock arm for forcibly displacing the lock arm from the locking position to the unlocking position as the slider is moved from the displacement restricting position to the displacement permitting position, at least one of the pushing portion and the pushable portion being formed with a slanted surface inclined with respect to both moving directions of the slider and displacing directions of the lock arm, the lock arm being forcibly displaced by the forcible displacement member as the slider is moved from the displacement permitting position to the forcible displacement position;
• a holding member cantilevered from the slider and configured for permitting movement of the slider in the displacement permitting position toward the forcible displacement position and restricting movement of the slider toward the displacement restricting position, and
• a biasing member mounted in the slider for biasing the slider from the forcible displacement position toward the displacement permitting position, wherein the lock arm is forcibly displaced by the forcible displacing member as the slider is moved from the displacement permitting position to the forcible displacement position, and wherein restriction on the movement of the slider toward the displacement restricting position by the holding member is released as the first connector housing is properly connected with the second connector housing.
