Abstract

A valve base 15 has: a valve base main body 20 on which a connector accommodating portion 37 and a board installing hole 38 are formed; a board assembly 42 provided with a plurality of output terminals and a plurality of input terminals connected to the output terminals by output wirings, and attached to the board installing hole 38; a relay connector 41 provided with a solenoid-side connection portion connected to a solenoid terminal and a board-side connection portion connected to the output terminals, and attached to the connector accommodating portion 37; and a through hole 55 provided on the valve base main body 20 so as to communicate with the connector accommodating portion 37, and exteriorly exposing a part of the relay connector 41. A manifold electromagnetic valve is formed by striking the valve bases 15 against each other. A type of solenoid valve is indicated by the relay connector 41 attached to the valve base 15.

Dependent claims

A manifold solenoid valve having at least one solenoid valve unit that includes a solenoid valve provided with at least one solenoid and a valve base mounting the solenoid valve, the manifold solenoid valve comprising:

a board assembly in which a plurality of input terminals and a plurality of output terminals connected to the respective output terminals by output wirings are provided and that is attached to the valve base;
a relay connector that is provided with a solenoid-side connection portion connected to a terminal of the solenoid and a board-side connection portion connected to the output terminal and that is attached to the valve base;
and
a through hole that is provided on the valve base and that exteriorly exposes a part of the relay connector attached to the valve base;
wherein the valve base includes a board insertion face, a side surface opposite to the board insertion face, a solenoid valve mounting face and an end wall portion that intersects the board insertion face, the side surface and the solenoid valve mounting face;
a board installing hole to which the board assembly is attached is formed on the valve base, penetrating the board insertion face and the side surface;
the through hole is formed in the end wall portion, penetrating the end wall portion;
wherein the relay connector has:
a plus common type first relay connector in which a plus side solenoid terminal of the at least one solenoid is connected to a common connection portion;
a minus common type second relay connector in which a minus side solenoid terminal of the at least one solenoid is connected to a common connection portion, and
any of the plus common type first relay connector and the minus common type second relay connector is attached to the valve base.
