合している。The assembly of the connector with lever is performed as follows. First, the pair of levers 8, 8 of the lever member C is temporarily expanded outward by utilizing its flexibility, and the shaft hole 10 is externally inserted into the pin 7 of the female connector B. At this time, the connecting portion 9 of the lever member C is engaged with the rear end of the front outer peripheral wall of the female connector B, so that the opening end 11a of the cam groove 11 coincides with the pin guide portion 6 of the female connector B. In this state, the male connector A is stably held at the fitting receiving position. At this time, the free end of the lever 8 of the lever member C is slidably engaged in the detachment preventing portion 4b provided on one side of the housing body 4.

A female terminal T and a male terminal U are provided inside the lever member C, respectively.
As shown in FIG. 1, for example, the fitting force per unit cross-sectional area from a large one to a small one toward the outer peripheral portion with respect to the fitting shaft I 'of the connector passing through the pins 7, 7 as the rotation support shafts is shown in FIG. As described above, the male terminal U and the female terminal T are arranged gradually from a large contact area per unit sectional area to a small contact area, so that the fitting axis I of the male connector A becomes the fitting axis I of the female connector B. ′, No bias occurs. Therefore, female connector B
The fitting operation of the male connector A into the inside is performed smoothly without being caught. Further, after fitting, no gap is formed between the female connector B and the male connector A unlike the conventional case, and rattling does not occur. In addition, the contact between the female terminal T and the male terminal U per unit cross-sectional area is good and excellent electrical conduction is achieved. The large fitting force between the female terminal T and the male terminal U per unit cross-sectional area means that the contact area is large or small. Even if the fitting lengths are arranged from long to short, or even if they are the same length, the number of male terminals U and female terminals T near the fitting axis I 'is increased. To increase the fitting force per unit cross-sectional area, and increase the number of male terminals U and female terminals T toward the outer periphery so that the number gradually decreases.
It is also conceivable that the fitting force per unit cross-sectional area gradually decreases toward the outer peripheral portion by being arranged.
