Abstract:
1. A solenoid valve comprising: a main valve portion having a valve member for switching a flow path; an electromagnetic manipulator for manipulating the valve member along an axis line, the electromagnetic manipulator being coupled with the main valve portion and comprising a hollow bobbin around which an exciting coil is wound, a fixed iron core and a movable iron core accommodated in the bobbin, a magnetic cover formed by a rectangular hollow member, which has one end closed by an end wall portion and in which the bobbin is accommodated in a state that the first end in an axial direction faces the end wall portion, and a pair of coil terminals electrically conducting to the exciting coil; a pair of terminal insertion holes formed to the end wall portion of the magnetic cover so that the coil terminals are individually inserted thereinto, wherein the coil terminals extend from the first end of the bobbin in parallel with the axial line to the outside of the end wall portion, passing through the terminal insertion holes in an electrically insulated state due to the interposition of rubber bushes; a print board, which is electrically connected to the coil terminals, and is disposed on the outside surface of the end wall portion in an electrically insulated state to the end wall portion; an electrically insulating protection cover disposed so as to cover the print board; and power receiving terminals disposed to the print board to connect an external connector for supplying power, wherein the protecting cover has a rectangular shallow dish shape and includes a main portion and an extending portion, a tip end of a side wall of the main portion abutting against an upper end portion of the magnetic cover in a state to entirely cover the print board, and the extending portion extending from an end of the main portion along one side surface of the magnetic cover and partially covering the side surface in a state to keep a space between the side surface and the extending portion, and a plurality of terminal taking out holes are formed to the extending portion, and wherein the power receiving terminals project from the protecting cover in a direction perpendicular to the axial line through the terminal taking out holes after extending from the print board along the extending portion through the interior of the space.
