Patent ID: 7722385

Claim:
A connector, comprising: a housing connectable with a mating housing, a lock arm provided displaceably on the housing and formed with a lock hole at front end portion thereof; a detector mounted movably relative to the lock arm between a standby position and a detection position, a latch formed on the detector and engaging the lock hole when the housing is not connected to the mating housing and when the detector is at the standby position for preventing the detector from moving to the detection position, the lock arm moving onto a lock projecting on the mating housing during connection of the housing with the mating housing for causing the lock arm to incline resiliently together with the detector; the lock arm restoring resiliently to engage the lock of the mating housing with the lock hole and to disengage the latch from the lock hole when the housings reach a properly connected state for locking the housings together and for enabling the detector to move toward the detection position, wherein an ability to move the detector to the detection position determines whether the housing is connected properly to the mating housing, and wherein at least one reinforcing rib projects from the lock arm for preventing the lock arm from deforming out of engagement with the detector before the housings are connected properly.
