Furthermore, the conductor 14 is provided with a claw 21 on the insertion portion 18 that is curved from the surface of the insertion portion.

This claw is formed by cutting the central part of the insertion part 18 into a U-shape and bending the three edges of the band-shaped part separated from the insertion part 18 upward.

Therefore, the claw 21 formed integrally with the insertion portion 18
When the curved end portion is pressed, it elastically deforms and enters the punched opening 22 of the insertion portion 18, and as a result, the upper surface of the insertion portion 18 becomes flat.

However, when the pressing force on the pawl 21 is released, the pawl 21 moves to the second position.
It returns to its warped state as shown in the figure.

The curved end of the claw 21 is connected to the insertion portion 1 so as to be suitable for preventing the conductor from falling off from the holder, which will be described later.
