0 and the metal plate 22 are likely to sandwich the electric wires 3 and 3, and when the electric wires 3 and 3 are broken, the broken portion is deleted to shorten the electric power. The space between the back side of the device 20 and the metal plate 22 may be abruptly narrowed, and there is no room for a driver to enter, making it impossible to connect the electric wires 3 and 3. However, the first terminal piece 1 and the second terminal piece of the present embodiment
According to the terminal device including the terminal piece 2, the crimping work can be performed with a finger without using a tool, so that a finger can be inserted between the back side of the electric device 20 and the metal plate 22. It suffices if there is a sufficient space, and the length of the electric wires 3 drawn from the mounting surface can be short. Therefore, when the electric device 20 is screwed and fixed to the metal plate 22 with the screws 21, 21, ..., The electric wires 3 and 3 drawn out from the mounting surface do not interfere with the electric device 20 and the metal device. It is possible to prevent the worst case in which the electric wires 3 are sandwiched between the plate 22 and the plate 22.

る。As described above, when the terminal device of this embodiment is mounted on the electric device 20, it is very convenient when connecting and fixing the electric wires 3, 3 to the electric device 20. For example, according to the conventional screw tightening type terminal device, as shown in FIG. 10, a space for working with a screwdriver is required between the back side of the electric device 20 and the metal plate 22. Many lengths of wire 3,3
Have to pull out. Therefore, the electric device 20
When fixing the screws to the metal plate 22 with the screws 21, 21, ..., The electric wires 3 and 3 drawn out from the mounting surface easily become an obstacle, and in the worst case, the electric device 2
0 and the metal plate 22 are likely to sandwich the electric wires 3 and 3, and when the electric wires 3 and 3 are broken, the broken portion is deleted to shorten the electric power. The space between the back side of the device 20 and the metal plate 22 may be abruptly narrowed, and there is no room for a driver to enter, making it impossible to connect the electric wires 3 and 3. However, the first terminal piece 1 and the second terminal piece of the present embodiment
According to the terminal device including the terminal piece 2, the crimping work can be performed with a finger without using a tool, so that a finger can be inserted between the back side of the electric device 20 and the metal plate 22. It suffices if there is a sufficient space, and the length of the electric wires 3 drawn from the mounting surface can be short. Therefore, when the electric device 20 is screwed and fixed to the metal plate 22 with the screws 21, 21, ..., The electric wires 3, 3 drawn out from the mounting surface do not interfere with the electric device 20 and the metal device. It is possible to prevent the worst case in which the electric wires 3 are sandwiched between the plate 22 and the plate 22.
