Enters. In the fitting preparation state, the above-mentioned contacted portion (not shown) contacts the above-described contact portion (not shown), and the slider 17 is positioned with respect to the female connector 3. Each of the two protrusions 59 of the male connector 13 is located immediately below the opening of each of the two guide grooves 69 formed obliquely.

  Subsequently, by rotating the lever 5 (by rotating the first member 33 of the lever 5 shown in FIG. 5 clockwise), the slider 17 is directed in the vertical direction from one end side to the other end side. (The direction in which the abutted part moves away from the abutting part; rightward in FIG. 9A), the protrusion 59 of the male connector 13 is moved upward by the guide groove 69 of the slider 17, and the male connector 13 is female. The connector 3 is fitted.

  When the fitting is finished or just before the end, the members 33 and 35 of the lever 5 extend substantially in the vertical direction (see FIG. 10). Thereby, a toggle mechanism is formed, and the force for fitting the male connector 13 to the female connector 3 is increased.

  Note that the male connector 13 is detached from the female connector 3 by performing an operation opposite to that described above.

  According to the lever-type connector 1, when the lever 5 is in a predetermined posture with respect to the female connector 3, the first lever engaging portion 9 and the connector engaging portion 15 are maintained while maintaining the shapes thereof. Since the lever engaging portion 9 can be engaged with the connector engaging portion 15, it is not necessary to deform the lever 5 or the female connector 3 when the lever 5 is assembled to the female connector 3. Thereby, even if the lever 5 is made of a highly rigid material such as metal, the lever 5 can be easily assembled to the female connector 3.

  Further, according to the lever-type connector 1, the first lever engaging portion 9 is configured by a notch in which the value of the width B1 of the opening-side portion 19 is smaller than the value of the diameter D1 of the deep-side portion 21. The value of the diameter D2 measured from the predetermined first direction is equal to or less than the value of the width B1 of the portion 19 on the opening side, and the value of the diameter D3 measured from the predetermined second direction is Since the connector engaging portion 15 is constituted by a protrusion equal to the diameter D1 of the portion 21, when the lever 5 is assembled to the female connector 3, the first lever engaging portion 9 and the connector engaging portion 15 are deformed. There is no need to let them. Thereby, even if the lever 5 is made of a highly rigid material such as metal, the lever 5 can be easily assembled to the female connector 3.

  Further, according to the lever type connector 1, the material constituting the first slider engaging portion 25 of the lever 5 and the material constituting the second lever engaging portion 27 of the slider 17 are different from each other. The rigidity of the first slider engaging part 25 is higher than the rigidity of the second lever engaging part 27, and the first slider engaging part 25 is engaged with the second lever engaging part 27.
