An elastic contact piece 52 that can be elastically deformed in the vertical direction is provided on the upper surface inside 1. The elastic contact piece 52 is fixed to the fitting portion 51 on the base side 52A, while being fixed to the distal end side 52A.
B is slidable in the front-rear direction while contacting the upper surface of the fitting portion 51. Further, the intermediate portion of the elastic contact piece 52 is bent downward to form a contact portion 53, which can be brought into contact with the male terminal fitting 3 with a predetermined contact pressure. When the male terminal fitting is inserted into the fitting part 51, the contact part 53 is pushed upward, and the elastic contact piece 52 bends upward. At this time, the distal end side 52B is displaced to the rear side of the female terminal fitting 50 while being in contact with the inner surface of the fitting portion 51.

しまう。In the above-described female terminal fitting 50, the spring constant of the elastic contact piece 52 is increased to a certain degree in order to set the contact pressure between the male and female terminals to a predetermined set value. I have to keep it aside. Here, for example, when it is necessary to increase the set value of the contact pressure of both terminals, the thickness of the plate material forming the female terminal fitting 50 may be increased, or the elastic contact piece 52 may be doubled. And the like. The elastic contact pieces 52 formed by such a method have the same thickness in the front-rear direction. For this reason, the spring constant of the elastic contact piece 52 is equal over the entire length from the base side 52A to the distal end side 52B, and the force F from the male terminal fitting 3 is applied to the two places of the base side 52A and the distal end side 52B. Will receive it. Then, Figure 1
As shown in FIG. 2, the force F is applied to the base side 52A and the distal side 52B.
At the stresses G1 and G3. For this reason, when the contact pressure of the male and female terminal fittings is increased, the frictional force H (proportional to the stress G3 at the distal end side 52B) when the distal end 52B moves to the rear of the female terminal fitting 50 is increased. It becomes difficult to perform a smooth operation when the male terminal fitting 3 is inserted.

Will be combined. For this reason, as compared with the case where the tip of the auxiliary elastic piece 10 is in contact between the raised contact portion 17 and the base side 20, the tip of the elastic contact piece 7 is made smoother while increasing the contact pressure of the male terminal fitting 3.
