2 to 4 show an embodiment of the present invention, in which the presser washer 3 is different from the conventional example shown in FIG.
The difference is that an auxiliary metal fitting 5 having an upwardly U-shaped cross section is disposed between the terminal plate 1 and the terminal plate 1. As shown in FIG. 3, the auxiliary fitting 5 is formed by bending a metal plate into a U-shaped cross section with an upward opening, and has a through hole in the center of the horizontal plate part 5a for the insertion of the tightening screw 2. 6 are bored, and notches 7,
7 is engraved on it. In this way, the tip of the tightening screw 2 that has passed through the spring washer 10 and the presser washer 3 is inserted into the through hole 6 of this auxiliary metal fitting 5.
After inserting it into the terminal plate 1, screw it into the presser washer 3.
Different types of electric wires 4, 4a are inserted between the lower surface and the upper surface of the horizontal plate portion 5a of the auxiliary metal fitting 5, and between the upper surface of the terminal plate 1 and the lower surface of the horizontal plate portion 5a of the auxiliary metal fitting 5, and in this state, the As shown in the figure, the electric wires 4, 4a are connected by tightening the tightening screw 2.

するようなことがない利点を有するものである。 As described above, the present invention provides that different types of electric wires are clamped and clamped between the upper surface of the terminal board and the lower surface of the horizontal plate of the auxiliary metal fitting, and between the upper surface of the horizontal plate part of the auxiliary metal fitting and the lower surface of the presser washer. This has the advantage that even if there is a large difference in wire diameter between the two wires, the wires will not come off or heat will not be generated due to poor contact.
