Patent ID: 8292650

Claim:
A lever-type connector, comprising: a first housing and a second housing connectable with each other, and a lever, wherein: the first housing includes a main body and has the lever mounted on an outer surface thereof, the lever includes a cam receiving portion and an operable portion, the cam receiving portion having an introducing groove extending in substantially forward and backward directions from an initial position and a connection cam surface extending in a substantially curved manner from the back end of the introducing groove and in which a radius of curvature is smaller at a final stage than at an initial stage of the connecting process, the lever being displaceable between an initial position where the operable portion is distant from a specified portion of the first housing and a connection position where the operable portion is near the specified portion of the first housing, the second housing includes a cam, a cam action is displayed between the cam and the first housing by displacing the lever from the initial position toward the connection position with the cam engaged with the cam receiving portion so that the first and second housings are connected with each other, and at least one pressing portion formed on the lever presses at least one pressable portion formed on the first housing only if the first and second housings are inclined from proper connection postures thereof at a final stage of a connecting process, whereby the connection postures of the first and second housings substantially are corrected, wherein the connection cam surface is configured so that a connection force of the first and second housings reaches a maximum value when the cam reaches a final position at the connection cam surface and when the operable portion is at a position near the specified portion of the first housing or overlapping the specified portion of the first housing and substantially immediately before the pressing portion presses the pressable portion in the connecting process of the first and second housings so that inertia generated to overcome the maximum value of the connection force carries the lever to the connection position without an operator perceiving forces for correcting connection postures of first and second housings.
