According to the present invention, the first separation terminal block and the second separation terminal block can be separated from the base, respectively, so that the electric wiring connected to the first separation terminal block can be reduced. When releasing the electrical connection with the electric wiring connected to the second separation terminal block, the first separation terminal block or the second separation terminal block or The first separation terminal block and the second separation terminal block are removed from the base. Thereby, the electrical connection between the electric wiring connected to the terminal of the first separation terminal block and the electric wiring connected to the terminal of the second separation terminal block can be easily released.
Therefore, the electrical connection of the electrical wiring and the release of the electrical connection can be easily performed without removing the electrical wiring from the terminal.

Further, since the first separation terminal block and the second separation terminal block can be separated from the base, the electric wiring connected to one of the separation terminal blocks can be connected to another arbitrary separation terminal block. Can be replaced with electrical wiring connected to Therefore, the electric wiring can be easily changed by replacing the other electric wiring with another separated terminal block connected to the terminal.

The connecting means is not particularly limited as long as it can electrically connect the terminals of the first separation terminal block and the terminals of the second separation terminal block via the base. Further, the fixing means fixes the first and second separation terminal blocks to the main body, and maintains an electrical connection state between the terminals of the first separation terminal block and the terminals of the second separation terminal block.
