When one side (right side in Figure 7) of the bending portion 420 is deformed to be lowered, and the interruption connector 200 and the male connector 300 is pushed to the side by the external force (that is, When the left and right distances of the interrupt connector 200 from the female connector 100 is changed) the bending part 420 is deformed to be bent in the lateral direction. For reference, since the female terminal 400 is formed in the shape of a metal pin like a terminal applied to a general connector, the female terminal 400 has a restoring elastic force to be restored to its original state when the applied external force is bent to one side by an external force. The bending part 420 which is a part of the terminal 400 also has the above resilient elastic force. That is, the bending part 420 not only has a restoring elastic force in the bending direction but also has a restoring elastic force in the vertical direction and the lateral direction. As mentioned above, since the metal pin-shaped terminal has restoring elasticity in the vertical direction and the lateral direction, it is a fact recognized by those skilled in the art to which the present invention pertains, and thus a detailed description thereof will be omitted. .

The point between the rear end and the end of the breaker connector 200, that is, the bending portion 420 is deformed, the bending portion 420 has a restoring elastic force not only in the bending direction but also in the vertical direction and the lateral direction as mentioned above. Therefore, when the external force that pushes the stop connector 200 and the male connector 300 downward or sideways is released, the stop connector 200 and the male connector 300 are moved by the restoring elastic force of the bending part 420. The position is returned to the state shown in 7.

In addition, the bending part 420 is also deformed when the breaker connector 200 and the male connector 300 are rotated such that the rear end of the male connector 300 is lifted as shown in FIG. 9. When the external force for rotating the stop connector 200 and the male connector 300 is released, the stop connector 200 and the male connector 300 return to the state shown in FIG. 7 by the elasticity of the bending part 420. do.

In this case, the bending number of the bending part 420 may be changed to one or three times or more according to the specifications of each terminal or the characteristics of the female terminal 400.

In addition, the female terminal 400 has a contact portion 410 which is bent or bent to protrude upward and is in contact with the male terminal 500 exposed to the inner upper surface of the insertion groove 310. The upper end of the contact portion 410 is configured to protrude to a point slightly higher than the bottom surface of the male terminal 500, the contact portion 410 is pressed downward when the contact portion 410 is in contact with the male terminal 500 do. That is, the female terminal 400 has its own elasticity to closely contact the contact portion 410 to the male terminal 500 when the contact portion 410 contacts the male terminal 500 as shown in FIG. 8. Bar, the contact between the female terminal 400 and the male terminal 500 is improved.

In addition, in the state shown in FIG. 7, the male terminal 500 and the male connector 300 are moved to the rear so that the contact between the female terminal 400 and the male terminal 500 is not released. The protrusion 510 is formed to protrude downward on a path through which the contact part 410 passes when the female connector 100 and the stop connector 200 are coupled to each other. Therefore, the breaker connector 200 and the male connector 300 may be moved backwards even with a relatively small external force until the contact portion 410 contacts the protrusion 510, but the contact portion 410 may be moved toward the protrusion 510.
