Patent ID: 7275951

Claim:
A connector comprising: a connector housing for receiving a terminal; a locking arm connected with the connector housing, the locking arm having a front end to be engaged with an engaging portion of a mating connector, and an operating portion at a rear end thereof; a locking securing unit movably attached to the connector housing, the locking securing unit being movable between a regulation position to regulate a resilient deformation of the locking arm and an allowance position to allow the resilient deformation thereof; and deformation switching portions disposed on the locking arm and the locking securing unit for allowing and regulating the resilient deformation of the locking arm, wherein when the locking securing unit is in the allowance position and the operation portion is operated, the deformation switching portions interfere each other and the locking arm resiliently deforms so that the front end of the locking arm moves upwardly to disengage from the engaging portion, and when the locking securing unit is in the regulation position and the operation portion is operated, the deformation switching portions separate each other and the locking arm is regulated to resiliently deform so that the front end of the locking arm is regulated to move upwardly to disengage from the engaging portion.
