Patent ID: 7677908

Claim:
A lever type connector comprising: a first connector housing; a second connector housing including a projection and a pin; and a lever pivotally engaged with the first connector housing and including two arm plates and an interconnecting bar which connects the two arm plates, wherein the each arm plate comprises: a pivotal support about which the lever pivots; a cam groove including an inlet and an end wherein a distance between the cam groove and the pivotal support gradually decreases from the inlet to the end, and the pin is inserted into the cam groove through the inlet; a provisional-retaining projection projecting from the arm plate toward the other arm plate, which abuts to the projection and causes to deform the arm plate so that the arm plate recedes to the other arm plate when the pin is inserted into the cam groove through the inlet; and a cancellation lever extending from an edge of the arm plate and positioned at a counter side of the inlet with respect to the pivotal support wherein the cancellation lever causes to deform the arm plate so that the arm plate recedes to the other arm plate when the cancellation lever of the arm plate is pressed to come close to the cancellation lever of the other arm plate, wherein the pin slides along the cam groove so as to connect the first and the second connector housings when the lever pivot about the pivotal support.
