Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a solenoid valve device with a printed wiring board used in an industrial machine that utilizes fluid pressure or vacuum pressure.

[Prior Art] Conventionally, in a solenoid valve in which pilot valves are provided on both sides of a valve body, power is supplied by connecting power supply lines to each of the pilot valves on both sides.

With such conventional solenoid valves, the power supply lines are connected to each pilot valve separately, so if a large number of solenoid valves are arranged on a manifold, for example, it is necessary to handle a large number of power supply lines. However, the disadvantage is that the number of man-hours for assembling and maintaining and inspecting the solenoid valve increases, resulting in high costs.

[Problems to be solved by the invention] This invention supplies power to the pilot valves provided on both sides from only one side, simplifies the power supply to the pilot valves, reduces the man-hours for assembly and maintenance, and Therefore, reducing the cost of solenoid valves is a technical problem to be solved.

[Means for Solving the Problems] The present invention provides a base in which a plurality of fluid passages are formed, and a solenoid valve equipped with two pilot valves protruding from both sides of the base through a printed wiring board. In the electromagnetic valve device, a power receiving terminal of an electromagnetic portion is formed protrudingly on each of the pilot valves, and a plurality of fluid passages of the base and each opening of the electromagnetic valve are respectively connected to the printed wiring board. providing a separate opening for communication, and providing an extension extending from the base in the direction of both pilot valves, and providing a power receiving terminal into which the power receiving terminal of the pilot valve is inserted in both extensions of the printed wiring board; The above-mentioned problem is solved by printing and wiring an electric circuit between both of the power supply receiving terminals and a connecting terminal for connecting them to a power source on one extension part.

[Function] In the above-mentioned solenoid valve device, when the solenoid valve with pilot valves provided on both sides of the valve body is mounted on the base, an opening is provided between them for communicating the fluid passage of the base and the opening of the solenoid valve separately. A printed wiring board is interposed, but this printed wiring board has
The power receiving terminals for the pilot valve are provided on the extensions extending on both sides, and the connection terminals for connecting these power receiving terminals to the power source are provided on one extension, and both power receiving terminals and the connection terminal are printed. Since the electrical connection is made by wiring, even if the valve is a solenoid valve with pilot valves on both sides of the valve body, there is no need to connect separate power supply lines to the pilot valves on both sides, and the power supply to those pilot valves can be connected using printed wiring. This can be done all at once from only one side of the plate, simplifying the wiring connection for energizing both pilot valves. Moreover, the electrical connection between the power receiving terminal of the pilot valve and the power receiving terminal of the printed wiring board can be completed at the same time as the installation of the solenoid valve, eliminating the need for individual wiring work for the pilot valve and allowing the solenoid valve device to Since the man-hours for assembly and wiring inspection are significantly reduced, the cost of the solenoid valve device can be reduced.
