て、極めて実効の高いものである。EFFECTS OF THE INVENTION In the terminal block of the present invention, unlike the conventional terminal block, it is not necessary to connect the terminals of the adjacent terminal block units 1 by the short-circuit wire, so that the number of wiring steps can be reduced. Also, when the moving element 8 is at the first position,
First secondary-side connected object 13 to primary-side connected object 12
When only the second mover 8 is in the second position, the second mover 8 is in the second position, and the second mover 8 is in the first position. When it is between the second positions, neither of the first and second secondary side connected objects 13 and 14 is connected to the primary side connected object 12. Therefore, the first secondary side connected article 13 and the second secondary side connected article 14 are not simultaneously connected to the primary side connected article 12, and erroneous wiring can be prevented. Further, since the connector 10 is pressed against each terminal by the springs 9 and 11, the reliability of electrical connection is high. Further, since the connection can be switched by simply rotating one knob 7B, the labor for switching can be reduced. Further, the primary side terminal 3 and the first
The secondary side terminal 4 and the second secondary side terminal 5 can be arranged side by side in a straight line in the longitudinal direction of the terminal block, and like the conventional terminal block, the first terminal and the second terminal are Since they are not arranged side by side, the width of the terminal block unit 1 can be reduced to about half, and the terminal block can be downsized. Therefore, it is extremely effective.
