When the male connector is joined to the connector assembled with the female terminal fitting, the male terminal fitting C is inserted between the elastic contact pieces 12 through the insertion opening 42 of the protective cover B. Then, the elastic contact piece 12 is changed from the state of FIG.
When it is inserted, it is pushed outward and flexibly deforms outward. Then, as shown in FIG. 8, the elastic auxiliary piece 45 is contacted with the elastic auxiliary piece 45 provided on the protective cover B, and thereafter the elastic auxiliary piece 45 is contacted.
It flexes and deforms with it. Therefore, the elastic contact piece 12 is urged by the elastic auxiliary piece 45 in the direction opposite to the bending deformation direction, and when the male side terminal fitting C is inserted in the regular position, the male side terminal fitting C is pushed by the elastic contact piece 12. The elastic force of itself,
It is strongly sandwiched by the elastic force acting from the elastic auxiliary piece 45.

5, the elastic contact piece 12 is biased in the direction opposite to the bending deformation direction, so that the male side terminal fitting C can be strongly sandwiched between the elastic contact pieces 12 and contact with the male side terminal fitting C can be made. The pressure can be increased. In particular, the present embodiment is effective in reducing the size of the female-side terminal fitting because the contact pressure can be increased without increasing the plate thickness. Further, since the tip end portion of the elastic contact piece 12 is biased by the elastic auxiliary piece 45 in the direction opposite to the bending deformation direction,
Compared with urging the base portion of the elastic contact piece 12, the elastic contact piece 12 can be efficiently urged in the direction opposite to the bending deformation direction, so that the male terminal fitting C can be contacted with a small urging force. The pressure can be increased.
