Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a solenoid valve manifold, in particular:
Each solenoid valve is connected to a control device by a flat cable, and parallel electrical signals sent via the flat cable are selectively distributed to each solenoid valve to control energization and deenergization. This invention relates to a solenoid valve manifold constructed as follows.

In fluid control systems, when a large number of solenoid valves are used in equipment or machinery, they are often assembled into a single block by constructing a manifold to simplify piping work and reduce installation space. In this case, the wiring to the solenoid coils etc. that make up each solenoid valve usually has to be done using several electric wires for each solenoid valve, and in particular the connection between the terminal of the solenoid coil and the electric wire is necessary. When doing this, the work becomes extremely complicated, and there are disadvantages such as the fact that it is not easy to increase or decrease the number of solenoid valves installed in series on the base.

Therefore, an object of the present invention is to provide a solenoid valve manifold that facilitates the connection between a solenoid valve and a control system for controlling the solenoid valve, and also allows for extremely easy maintenance and management in which it is extremely easy to increase or decrease the number of solenoid valves connected to the manifold. The purpose is to

In order to achieve the above object, the present invention configures a solenoid valve manifold with a plurality of solenoid valves and a manifold on which the solenoid valves are mounted, and connects a wiring assembly consisting of a flat cable electrically to the solenoid valves. It is characterized in that it is connected and sends a control signal to a predetermined solenoid valve.

Next, preferred embodiments of the solenoid valve manifold according to the present invention will be described in detail with reference to the accompanying drawings.

First, FIG. 1 is an electrical wiring diagram of a solenoid valve manifold according to the present invention. In the figure, reference numeral 10 indicates a solenoid, and reference numeral 12 indicates a selection switch. A plurality of wires 14a to 14h are led out to the selection switch 12, and each of the wires 14a to 14h is connected to the wires 18a to 18h constituting the flat cable 16, respectively. One end of the wires 18a to 18h is connected to a first connector, as will be described later, and the other end is connected to a second connector. Also, one of the two lines 20 derived from the above 10 is connected to the selection switch 1.
2 and the other line 22 is connected to a common line 24.

Although not shown in the figure, it goes without saying that the number of solenoids 10 corresponding to the number of flat cables 16 excluding the wire 24 is provided.

In this case, the selection switch 12 may be one in which one terminals of a number of switches are connected to each other as shown in FIG. 2(A), or a rotary type switch as shown in FIG. 2(B). Furthermore, it may be of a selection push button type.

Therefore, the selection switch 12 and the like configured as described above are actually incorporated as shown in FIGS. 3 to 5.

That is, according to this embodiment, the solenoid valve manifold 2
A second connector 3 into which a first connector 32 protruding from a solenoid valve 30 is fitted onto the upper surface of a rectangular parallelepiped main body 28 constituting a second connector 3;
4 are arranged. On the other hand, a connector 36 is similarly formed on the front surface of the main body 28, and a connector 38 that fits with this connector 36 is formed protruding from the back surface of the connection block 40.

As can be easily understood from FIG. 3, the connection block 40 is formed in a stepped shape, and the selection switch 12 is disposed on the front surface of this block 40. A plurality of connectors 42 are arranged vertically on the back side of the selection switch 12, while a connector 44 to which a connector 42 of a separately prepared connection block 40 is fitted is arranged on the opposite surface of the connector 38. (See Figures 4 and 5)
.

Therefore, the connector 32 of the solenoid valve 30 is fitted into the connector 34 on the upper surface of the manifold body 28, and the third
As shown by broken lines in the figure, the plurality of step-shaped tangent blocks 40 are connected such that the connector 42 fits into the connector 44 of the other connection block 40, and a pair of tangent blocks 40 protruding from the connection block 40 are connected. If the connector 38 is fitted into the connector 36 formed on the manifold body 28,
Solenoid valve 30, manifold 28 and connection block 40
are electrically connected, and thus the circuit shown in FIG. 1 is constructed. Therefore, the selection switch 12
When one of the buttons is selected, one of the lines 18a to Hlh of the flat cable 16 is selected, and the solenoid valve 30 is energized or de-energized by the signal sent from that line. The situation will be strengthened.

Next, FIG. 6 shows another embodiment. Note that the same reference numerals as those shown in the above embodiments indicate the same components.

In this embodiment, the connection block 40 is configured in the shape of a rectangular parallelepiped, and a connector 46 and a connector 48 are vertically connected near both ends of the front surface of the block 40.
A selection switch 12 is provided at the upper middle portion of the connectors 46 and 48. On the other hand, flat cable 1
A flat cable 50 including the flat cable 16 is prepared and its both ends are held between blocks 52 and 54.
A connector 56 that fits into the connector 46 is provided at one end of each of the wires 18a to 18h, and a connector 58 that fits into the connector 48 is provided in a protruding manner at the other end.

Therefore, the connector 32 of the solenoid valve 30 is fitted into the connector 34 of the manifold body 28, and further, the connector 38 of the connection block 40 is fitted into the connector 36 of the manifold body 28. Next, connect the connector 5 to the connector 46.
6, the connector 58 is fitted to the connector 48, and the respective connection blocks 40 are connected to the flat cable 5 in the same manner.
If the connection is made through 0, an electric circuit similar to that of the above embodiment will be connected.

Therefore, if any one of the lines 18a to 18h is selected by the selection switch 12, the solenoid valve 30 is controlled by the signal sent from the selected line, as described above. In addition, in the case of this embodiment, the connection block 40
It is also possible to integrate the manifold body 28 with the manifold body 28.

FIG. 7 shows yet another embodiment, and in this case too, the same reference numerals as those shown in the previous embodiment indicate the same components.

Therefore, in this embodiment, a -connector 60 and a connector 62 are provided on the left and right side surfaces of the connection block 40, which is configured in the shape of a rectangular parallelepiped. It was configured to be connected by 18h and 24. Therefore, the connector 60 of one connection block 40 is fitted into the connector 62 of another connection block 40 to connect the flat cable. Therefore, under the selection action of the selection switch 12, the connector 34 is
Control of the electromagnetic valve 26 connected to is achieved.

According to the present invention, as described above, wiring for controlling each of a plurality of solenoid valves connected in series can be easily connected by fitting the first and second pair of connectors of the connection block body. It becomes possible to connect the wires. Moreover, since the number of wiring assemblies for each solenoid valve is the same, the same connector can be used for any solenoid valve.
It is also extremely easy to wear. Furthermore, the signal corresponding to each solenoid valve can be freely selected using the selection switch, which simplifies the wiring of signal lines for the solenoid valves.For solenoid valves including double solenoids, flat cables can be used This reduces the risk of incorrect wiring, facilitates recovery in the event of a failure, and reduces manufacturing man-hours. Furthermore, restrictions on the number of consecutively installed manifolds due to wiring difficulties are removed, and the advantage is that the entire device can be standardized.

Although the present invention has been described above with reference to a preferred embodiment, the present invention is not limited to this embodiment. For example, the present invention is not limited to this embodiment. It goes without saying that various modifications can be made without departing from the spirit of the present invention, such as incorporating them into the manifold or connecting them later with the manifold.
