ことができる。As shown in FIG. 1B, the mating male terminal 20 (for example, a solenoid tab terminal) is formed through the punched hole 3 from the back side of the female terminal 1 (the lower side in FIG. 1B). It is inserted between the tips of the contact pieces 4 and 4 on both sides, and contacts these contact pieces 4 and 4. At this time, since the width W between the tip portions of the right and left contact pieces 4 and 4 is smaller than the thickness h of the mating male terminal 20, the contact pieces 4 and 4 rotate around the root portion and the left and right torsion portions 6 and 6 are rotated. Generates torsional stress. For this reason,
On the mating male terminal 20, not the elastic force due to the bending of the contact pieces 4, 4 but the elastic force due to the torsion of the torsion portion 6 mainly acts. Therefore, even when the spring lengths of the contact pieces 4 and 4 are short, the stress on the roots of the contact pieces 4 and 4 when the mating male terminal 20 is fitted and connected is small, and the roots can be plastically deformed. Properties are extremely small, and the contact pieces 4, 4
The contact reliability with the mating male terminal 20 can be increased.

く、この根元部が塑性変形する可能性は極めて小さい。The difference between the female terminal 51 in FIG. 3 and the female terminal 1 in FIG. 1 is that the contact piece 54 has four torsion portions 56, 56, 56,
6 extend one by one toward the center. These contact pieces 54 are bent upward (in a direction perpendicular to the plane of FIG. 3) so as to receive a mating male terminal (not shown). According to this, a mating male terminal having a substantially rectangular or circular cross section (not shown)
And the four contact pieces 54, 54, 54, 54 come into contact with the mating male terminal. Male terminal is contact piece 5
4, when contacted, like the female terminal 1 in FIG.
Since the elastic force due to the torsion of the torsion portion 56 mainly acts on the mating male terminal, the stress on the root portion of the contact piece 54 is small, and the possibility that this root portion is plastically deformed is extremely small.

の長さを短くすることができ、小型化が図られる。According to the present invention, when the mating male terminal comes into contact with the contact piece, the torsion formed by punching out the vicinity of the base of the contact piece is twisted, so that the mating male terminal comes into contact with the contact piece. Then, the elastic force due to the torsion of the torsion portion acts on the mating male terminal. Therefore, even when the spring length of the contact piece formed by punching and bending a metal flat plate is short, when the mating male terminal is fitted and connected, the contact piece is not plastically deformed. Therefore, the contact reliability of the contact piece with the mating male terminal can be increased. For this reason, the length of the contact piece itself of the female terminal can be shortened, and downsizing is achieved.
