Patent ID: 7976322

Claim:
A lever fitting type connector, comprising: a male connector; a lever which is rotatably attached to the male connector; and a female connector which has a fitting space into which the male connector is inserted, wherein the lever has a fulcrum protrusion provided on one end portion of the lever; wherein an inner wall forming the fitting space of the female connector has a guiding groove portion and a receiving groove portion for receiving the fulcrum protrusion; wherein the guiding groove portion extends in a fitting direction of the male connector with respect to the female connector from an upper end portion of the inner wall toward the inside of the fitting space; wherein the receiving groove portion is communicated with the guiding groove portion and extends in a direction intersecting the fitting direction from one end of the guiding groove portion which is away from the upper portion of the inner wall; wherein the lever has a temporary retaining portion for preventing the lever from rotating to the female connector at an initial fitting process; wherein the inner wall has a release portion for releasing engagement of the lever by the temporary retaining portion such that the lever is converted from an unrotatable state to a rotatable state; wherein when the lever is pressed toward the female connector so as to rotate the lever in a state where the fulcrum protrusion of the lever is positioned to the inside of the receiving groove portion, the fulcrum protrusion serves as a fulcrum, a center portion of the lever serves as an action point, and the male connector is pressed to the inside of the fitting space in the fitting direction; wherein the fulcrum protrusion is positioned to the inside of the receiving groove portion at a time when the unrotatable state of the lever is released; wherein an edge wall forming the receiving groove portion has a first taper wall and a second taper wall for guiding the fulcrum protrusion to the first taper wall; wherein the first taper wall is inclined so as to decrease a width of the receiving groove portion in a direction away from the guiding groove portion; and wherein the second taper wall is inclined so as to increase a width of the receiving groove portion in a direction from the first taper wall to the guiding groove portion.
