A technique to reduce workload on an operator during mating of a lever connector is provided. A plug and a receptacle are pulled together by rotation of a lever in a locking direction. The lever has a pinion first driven surface facing in an unlocking direction. A receptacle housing has a rack first driving surface facing in a separating direction. In a state where the plug confronts the receptacle so as to mate the plug with the receptacle, a clearance between the pinion first driven surface and the rack first driving surface is smaller than a clearance between a contact piece and a pin portion. When the plug is moved toward the receptacle, the pinion first driven surface first comes into contact with the rack first driving surface and the lever rotates in the locking direction, and then the contact piece comes into contact with the pin portion.

1. A lever connector comprising: a plug including:a plug contact including a plug contact portion;a plug housing that holds the plug contact; anda lever that is rotatably attached to the plug housing; anda receptacle including:a receptacle contact including a receptacle contact portion capable of coming into contact with the plug contact portion; anda receptacle housing that holds the receptacle contact,the plug and the receptacle being pulled together by rotation of the lever in a first rotation direction, wherein the lever has a lever driven surface that faces in a second rotation direction, the second rotation direction being opposite to the first rotation direction,the receptacle housing formed with a rack having a plurality of surfaces, one of the surfaces having a receptacle driving surface that faces in a separating direction, the separating direction being opposite to an approaching direction in which the plug is caused to approach the receptacle so as to mate the plug with the receptacle,in a first state where the plug confronts the receptacle so as to mate the plug with the receptacle, a first distance between the lever driven surface and the receptacle driving surface is smaller than a second distance between the plug contact portion and the receptacle contact portion, the first distance being equal to a distance of the movement of the plug toward the receptacle until the lever driven surface is brought into contact with the receptacle driving surface from the first state, the second distance being equal to a distance of the movement of the plug toward the receptacle until the plug contact portion is brought into contact with the receptacle contact portion from the first state, andwhen the plug is moved toward the receptacle, the lever driven surface is first brought into contact with the receptacle driving surface to cause the lever to rotate, in the first rotation direction, and after that, the plug contact portion is brought into contact with the receptacle contact portion. 2. The lever connector according to claim 1, wherein the plug includes a lever temporary holding mechanism that temporarily holds the lever in such a manner that the lever driven surface and the receptacle driving surface are opposed to each other in the approaching direction in a state where the plug confronts the receptacle so as to mate the plug with the receptacle,the lever temporary holding mechanism is formed of a temporary holding elastic piece that is supported by the plug housing in a cantilever manner,the temporary holding elastic piece hooks on to the lever, thereby inhibiting the rotation of the lever in the first rotation direction,when the plug is moved toward the receptacle, the temporary holding elastic piece is brought into contact with the receptacle and elastically deformed, andthe elastic deformation releases the inhibited state. 3. The lever connector according to claim 1, wherein the lever has a lever driving surface that faces in the first rotation direction,the receptacle housing has a receptacle driven surface that faces in the approaching direction, andwhen the lever is rotated in the first rotation direction in a state where the plug contact portion is in contact with the receptacle contact portion, the lever driving surface is brought into contact with the receptacle driven surface.
