まわりがコンパクトになる。Here, as shown in FIG. 5A, when the conductor P is inserted into the receiving portion 12, the conductor P hits the inner portion 21b of the contact portion 21, and the contact portion 21 is moved in the conductor insertion direction and It is pressed in a direction away from the receiving section 12. In this case, as shown in FIGS. 5B to 5C, the bending portion 22 is compressed and the angle G at the center of the bending portion (see FIG. 4B).
Is reduced, the back part 21b of the contact part 21 is
4 and almost the entire contact portion 21 is located at the boundary surface 14 a between the storage portion 14 and the receiving portion 12. For this reason, the contact portion 21 comes into contact with the conductor P on the entire surface, and the contact pressure that the conductor P receives from the contact portion 21 when the conductor is inserted is appropriately suppressed, and the force required for inserting the conductor P is reduced. . On the other hand, as shown in FIG. 6A, when the conductor P is removed from the receiving portion 12, the contact portion 21 is dragged in the conductor removal direction. In that case, as shown in FIGS. 6B to 6C,
The front part 21 a of the contact part 21 is the support wall 13 of the storage part 14.
And the back portion of the contact portion 21 as a fulcrum.
Rises toward the receiving portion 12 and is strongly pressed against the conductor P in a state almost close to point contact.
The force required to remove the conductor P increases, and the holding force of the conductor P in the connector C increases. Therefore, it is possible to achieve both improvement in handleability at the time of inserting the conductor and improvement in reliability of the connector C by strengthening the holding power of the conductor. Further, since a lock mechanism or the like is not provided, the cost of the connector C is reduced, and compactness is achieved. Furthermore, since the contact 20 is substantially upright with respect to the conductor P, the length of the connector C in the conductor insertion direction is reduced, and the conductor P
The circumference becomes compact.

To position. For this reason, the contact portion 121 comes into contact with the conductor P over the entire surface, and the contact pressure that the conductor P receives from the contact portion 121 when the conductor is inserted is appropriately suppressed, and the force required to insert the conductor P is reduced. . On the other hand, when the conductor P is removed from the receiving portion 112, the contact portion 121 is dragged in the conductor removal direction. In this case, the front part 121a of the contact part 121 hits the support wall 113 of the storage part 114, and the contact part 121 serves as a fulcrum.
Of the conductor P rises toward the receiving portion 112 and strongly presses against the conductor P in a state close to point contact, so that the force required to remove the conductor P increases,
The holding power of the conductor P in the male connector C is increased. Therefore, it is possible to improve both the handleability when inserting the conductor and the reliability of the male connector C by strengthening the holding power of the conductor. Further, since a lock mechanism or the like is not provided, the cost of the male connector C is reduced, and compactness is achieved.

が低減され、コンパクト化が達成される。When the harness B is crimped to the barrel 211 of the connector C and the conductor P is inserted into the receiving part 212, the conductor P hits the inner part 221b of the contact part 221 and the contact part 221 is moved in the conductor insertion direction and It is pressed in a direction away from the receiving part 212. In this case, since the curved portion 222 is compressed and the angle G at the center of the curved portion decreases, the contact portion 22
1 fits into the storage part 214 and the contact part 2
Almost the whole of 21 is located at the boundary surface 214a between the storage portion 214 and the receiving portion 212. Therefore, the contact portion 221 comes into contact with the conductor P over the entire surface, and the contact pressure that the conductor P receives from the contact portion 221 when the conductor is inserted is appropriately suppressed, and the force required to insert the conductor P is reduced. . On the other hand, when the conductor P is removed from the receiving portion 212, the contact portion 221 is dragged in the conductor removal direction. In that case, the contact portion 22
The front part 221a of the contact part 221 contacts the support wall 213 of the storage part 214, and the back part 221 of the contact part 221 is used as a supporting point.
Since b rises toward the receiving portion 212 and hits the conductor P strongly in a state close to the point contact, the force required for removing the conductor P increases, and the holding force of the conductor P in the connector C increases. . Therefore, the connector C is improved by improving the handleability at the time of inserting the conductor and enhancing the holding force of the conductor.
Can be improved at the same time. Further, since a lock mechanism or the like is not provided, the cost of the connector C is reduced, and compactness is achieved.

When the contact portion 221 is removed from the contact portion 221, the front portion 221 a of the sharp contact portion 221 bites into the support wall 213 of the storage portion 214.
