[Action]

 Attach the wiring board with the first conductive surface of the conductive socket attached to each power supply terminal to the terminal cover, and then attach this terminal cover to the solenoid valve or the wiring board with the above-mentioned conductive socket attached to the solenoid valve. When mounted on, the second conductive surface of each conductive socket holds the corresponding coil terminal, so that the power supply terminal and the coil terminal are electrically connected. In this case, by connecting the multiple power supply terminals and the corresponding coil terminals with separate conductive sockets, the distance between the multiple power supply terminals and the distance between the coil terminal terminals may differ due to manufacturing errors.

Further, since the conductive socket has a substantially U shape, and the first conductive surface is provided on the bottom side and the second conductive surface is provided on the tip side, the distance between each power supply terminal and the corresponding coil terminal is reduced. Even if there is a difference due to the above error, each power supply terminal and the corresponding coil terminal can be electrically connected.
