Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a manifold solenoid valve for serial-parallel transmission, which is constructed by mounting a plurality of solenoid valves on a manifold.

[Prior Art] Conventional manifold solenoid valves for serial-parallel transmission of this type include a plurality of driver circuits that drive individual solenoid valves installed on the manifold, and convert a serial signal, that is, a serial signal, into a parallel signal, that is, a parallel signal. Since a large printed circuit board with a serial-to-parallel converter attached thereto is housed in the manifold, the volume of the manifold becomes large, making it difficult to apply small electromagnetic valves. Furthermore, in the conventional method, when driving multiple manifold solenoid valves, the controller is connected to each manifold solenoid valve using electric wires, which has the disadvantage of complicating the wiring between the controller and each manifold solenoid valve. be.

[Purpose of the invention] In order to improve such conventional drawbacks, the purpose of the invention is to reduce the volume of the manifold so that a small solenoid valve can be applied, and also to make it possible to use a small solenoid valve even when multiple manifold solenoid valves are used. To provide a manifold solenoid valve for serial/parallel transmission, which allows the controller to be connected to only one manifold solenoid valve, thereby making the wiring between the controller and the manifold solenoid valve compact.

It may be provided in the solenoid portion 2a of the solenoid valve 2, or it may be provided in the main body portion 2b of each electromagnetic valve 2 as shown in FIG. 3b. By inserting the connector pin 14 of each solenoid valve 2 into the connector pin hole 7, the signal line 5 and power line 6 are connected to each solenoid valve 2, and an appropriate number of solenoid valves 2 are connected to one manifold 1. A manifold solenoid valve for serial/parallel transmission is constructed by attaching the .

In the above configuration, the parallel signal from the controller 15 is converted into a serial signal by an output unit (not shown), transmitted to the electrical connector 9, and then converted back to a parallel signal by the serial-parallel converter 4 in the manifold 1.
When this converted parallel signal is input to each solenoid valve 2 on the manifold 1, the light emitting element 1

need only be connected to the first manifold solenoid valve 16a. In the case of FIG. 4, a serial signal is transmitted to each manifold solenoid valve 16a, 16b, 16c, . . . as programmed in advance in the controller 15, and this serial signal is built in each manifold 1. The serial-to-parallel converter 4 converts the signal into a parallel signal to control and drive each electromagnetic valve 16a, 16b, 16c, . . . . In this way, by providing the electrical connectors 9 at both ends of each manifold 1, the plurality of manifold solenoid valves 16a, 16
