And a holding portion and a V-shaped portion.
Since the reaction force against the contact force applied to the contact is increased by the cooperative action with the letter-shaped portion, the printed circuit board to be inserted is warped, and the displacement amount of the contact spring contact portion is reduced. When the predetermined value is exceeded, the reaction force of the contact portion is increased, thereby acting to correct the warped printed circuit board.

５０の変位量を調整することができる。Next, referring to FIGS. 6 and 7, when the displacement of the spring contact portion 50 gradually increases from 0 and exceeds a certain value, the point c of the contact 40 comes into contact with the holding portion 46, and The load from the holding portion 46 is received. In this case, the amount of displacement of the spring contact portion 50 depends on the dimension of the contact 40 (that is, the height h from the point c to the vertex a of the hairpin-shaped holding portion 46; from the point c to the protruding end of the spring contact portion 50). Height k; and the distance m) between the hair pin-shaped holding portion 46 and the downward extension portion 48). Therefore, the displacement of the spring contact portion 50 can be adjusted by changing these numerical values.

とり方の如何によって、その増加が小さくなる。As described above, when the displacement of the spring contact portion 50 of the contact 40 is increased, the load applied to the contact is increased by the load on the point c. That is, in FIG. 6, when the displacement of the spring contact portion 50 and [delta] 1, load on the point c, i.e. as reaction force indicated by dotted lines,
The inclination becomes large, and in FIG.
Assuming that the displacement amount is δ 2 , the slope indicating the load on the point c increases. In addition, the increase in the stress at the point a becomes small depending on the dimensions, because the load on the point c is applied as a contact load and a counterclockwise moment.

部５０の頂点のａ点の応力を軽減することができる。According to the present invention, as will be apparent from the above description, when there is no reaction force to the point c based on the load and stress of each part with respect to the displacement of the spring contact part 50 of the contact. The stress at the point a at the apex of the spring contact portion 50 can be reduced when there is a reaction force, as compared to

ができる。Further, the spring contact portion 50 is connected to the holding portion 46 by c.
Since the contact is made at the point and the electrical connection is made, the conduction path from the contact portion 50 is shortened, and the high-frequency characteristics can be improved.

という効果がある。In particular, when the printed circuit board 12 is warped and the amount of displacement of the spring contact portion 48 is increased, the point c is designed to receive a reaction force. Since the contact load sharply increases, there is an effect that the warpage of the printed circuit board 12 can be corrected by the force.
