It is provided in the vertical direction of the figure. Therefore, when connecting the conductor 4 to the terminal fitting 1 by tightening or crimp terminal, even if the terminal screw 3 is over-tightened, when the four corners of the washer 2 are brought into pressure contact with the terminal fitting 1, Since the protrusion 9 presses against the washer 2, the terminal fitting 1 will not be deformed even if it is further tightened. Therefore, there is no risk of poor contact between the conductor 4 and the crimp terminal or crimp terminal, or poor contact between the plug and the blade receiver provided at one or both ends.

As described above, the present invention has a structure in which the terminal fitting has protrusions that are approximately the same height as the four corners of the washer, so even when the terminal screw is tightened,
Since the ridge provided at the corner presses against the terminal fitting and at the same time the protrusion presses against the opposing washer, the screw cannot be tightened any further, so the terminal fitting does not deform and the winding of the conductor is prevented. This has the effect of eliminating the possibility of poor contact with the fastening connection terminal or crimp terminal connection terminal, or poor contact between the blade receiver provided at one or both ends and the plug.
