め付けることにより配線を行うことができる。Next, the wiring connection in the terminal device of the present invention will be explained. In FIG. 1, when the terminal screw 5 is loosened, the terminal screw 5 engages with the screw groove of the screw hole 3 of the upper plate 2a of the cylinder portion 2 having a rectangular cross-section and moves upward, thereby causing the flat washer 9 to protrude. 8, a gap is created between the lower plate 2b of the terminal plate and the flat washer 9, and wiring of the bare wire 11 is performed by inserting the bare wire 11 into the gap and tightening the terminal screw. In that case, the bare wire is firmly fixed by the retaining claw 9a attached to the flat washer 9. In addition, for the wiring of the crimp terminal 10, the terminal screw 5 is attached to the cylindrical portion 2 having a rectangular cross section.
Wiring can be performed by loosening the terminal screw until it comes out of the through hole 4 of the lower plate 2b, inserting the retaining portion 7 into the hole of the crimp terminal 10, and tightening the terminal screw.

Then, by tightening the terminal screw, the retaining part 7 is attached to the lower plate 2b of the cylindrical part 2.
The crimp terminal 10 and the bare wire 11 are inserted into the through hole 4 of the cylindrical portion, and the crimp terminal 10 and the bare wire 11 are clamped and fixed between the lower plate 2b of the cylindrical portion and the flat washer 9 to prevent them from coming off. In addition, since the flat washer 9 is attached to the retaining portion 7 of the terminal screw with a play that allows it to move in the vertical direction, the retaining portion 7
Even when wiring with two crimp terminals or composite wiring with bare wires and crimp terminals is performed, the retaining portion 7 is attached to the lower plate 2b of the cylindrical portion 2.
It enters into the through hole 4 and is prevented from coming off.

する効果がある。According to the present invention, the cylindrical portion 2 has a rectangular cross section, the screw hole 3 is provided in the upper plate 2a of the cylindrical portion 2, and the through hole 4 is formed in the lower plate 2b of the cylindrical portion 2. The terminal board 1 has a threaded portion 6 that engages with the screw hole 3 of the upper plate 2a of the cylindrical portion 2, and a retaining portion 7 and a protrusion 8 are provided at the lower end of the threaded portion 6, and the protrusion 8 and the screw are provided at the lower end of the threaded portion 6. A terminal screw 5 having a flat washer 9 fixed with a certain play in the axial direction between the parts 6.
By inserting the threaded part 6 of the terminal screw through the screw hole 3, and passing the retaining part 7 of the terminal screw 5 through the through hole 4 of the lower plate of the cylindrical part, the flat washer and the cylindrical part are connected. Since the connecting conductor is clamped and fixed between the lower plate and the lower plate, wiring can be done without removing the terminal screw from the terminal board, and a flat washer can be attached to the terminal screw retaining part to prevent play in the axial direction. Since the retaining portion has a sufficient length to prevent the connector from coming off, it is possible to conduct wiring using two crimp terminals or composite wiring using a bare wire and a crimp terminal.
