Patent ID: 8882528

Claim:
A connector, comprising: a housing movable along a connecting direction for connection with a mating housing; a lock arm joined to the housing at an arm pivot and having an end resiliently displaceable toward and away from the housing, the lock arm being configured for locking the housing and the mating housing in their connected state; an unlock arm provided on the housing and extending along the connecting direction with the mating housing, the unlock arm being resiliently deformed like a seesaw so that both longitudinal ends thereof are displaceable in same directions as the lock arm toward and away from the housing about a pivot point at an intermediate position different from the arm pivot and being configured for releasing a locked state of the lock arm; at least one arm-side preventing portion formed on a lower surface of the unlock arm and projecting towards the housing; and at least one housing-side preventing portion formed on an upper surface of the housing and projecting towards the unlock arm; wherein the at least one arm-side preventing portion and the at least one housing-side preventing portion are configured for contacting one another at a position rearward of the pivot point when one of the ends of the unlock arm is displaced about the pivot point toward the housing for preventing excessive deformation of the unlock arm.
