Patent ID: 7717758

Claim:
A connector comprising: a housing having cavities extending along a fit-in direction and configured for receiving terminal fittings, the housing being formed with at least one locking part having a locking surface; and a retainer mounted on the housing and being movable in a movement direction oblique to the fit-in direction between a temporary locking position and a main locking position, the retainer being configured for allowing the terminal fittings to be inserted into the housing and removed therefrom when the retainer is at the temporary locking position, the retainer further being configured for preventing removal of the terminal fittings inserted into the housing when the retainer is at the main locking position, the retainer being formed with at least one to-be-locked portion having a locking surface that locks to the locking surface of the locking part when the retainer is at the main locking position, the locking surfaces of the locking part and the to-be-locked portion being aligned at an acute angle to the fit-in direction of the cavities and at an acute angle to the movement direction of the retainer wherein the retainer has a leading edge aligned parallel to the fit-in direction, the retainer further having front and rear ends spaced apart along the fit-in direction, the to-be-locked portion is disposed in proximity to the leading edge of the retainer, the to-be-locked portion inclining in a direction so that a distance between the to-be-locked portion and the leading edge of the retainer gradually increases from an end of the to-be-locked portion closer to the rear end of the retainer to an other end of the to-be-locked portion closer to the front end of the retainer.
