Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a manifold type electromagnetic valve device in which a plurality of valve bodies are installed on a manifold base and a coil block is attached to one or both sides of the valve body.

Conventionally, in order to conduct electrical wiring for this type of solenoid valve device, a separate socket was installed on the outside of each coil block of the valve body, and a separate cord was pulled out for each valve body, which required a large number of cords. The electrical wiring is scattered and drawn out to the sides of the valve body, requiring a large amount of space for electrical wiring, and has the disadvantage that wiring errors are common.

Therefore, as disclosed in Japanese Utility Model Application Publication No. 51-42526, a lead wire box is attached to the top surface of each of the plurality of valve bodies installed in parallel on the manifold base with bolts, and adjacent lead wires are connected to each other. A single lead wire passage is formed by connecting the boxes with bolts and nuts and communicating their internal parts, and the lead wires pulled out from the coil blocks of each valve body are collected in this lead wire passage. There is a device that can be inserted through it and pulled out from one end.

However, this method had the following drawbacks.

After the valve bodies are installed on the manifold base, a lead wire box is attached to the top of each valve body, and the lead wire boxes are then connected to each other. Therefore, when increasing or decreasing the number of valve bodies, it is necessary to attach the lead wire box for each valve body. Installation/removal and wiring work must be performed each time.

After the lead wire box is attached to each valve body with bolts, both left and right ends must be connected using bolts and nuts, which is troublesome to attach and remove.

After pulling out the lead wire directly from the coil block of the valve body and inserting it into the lead wire passage of the lead wire box, or connecting one end of the lead wire from the coil block to the connection terminal block provided in the lead wire box, Since another lead wire is drawn out from the connection terminal block, wiring work for the lead wire must be performed again when attaching or detaching the coil.

The purpose of the present invention is to provide a manifold that is easier to install and remove, especially when increasing or decreasing the number of valve bodies, eliminates the need for rewiring, and allows the whole to be compactly assembled, compared to conventional valve bodies. The purpose of the present invention is to provide a type solenoid valve device.

To achieve this objective, the present invention, referring to the illustrated embodiment, provides a hollow terminal block 8 corresponding to the coil block 6 of the valve body 2;
This is detachably attached to the side of the manifold base 1 instead of on the valve body 2. That is, a horizontally long joining groove 3 is formed on one or both substantially vertical sides of the manifold base 1, and a joining protrusion 12 is formed on one side of the terminal block 8. It is removably fitted into the groove 3. The terminal block 8 is also provided with a connecting flange 11 and an opening on its front and rear surfaces, so that the connecting flange 11 can be connected to each other.
By fitting the terminal block 1 and the opening into each other, the hollow part of the terminal block 8 is made to communicate with each other. Furthermore, a male terminal 7 is provided on the bottom surface of each coil block 6.
A female terminal 14 is provided on the upper surface of the terminal block 8, and when the valve body 2 is placed on the manifold base 1, the male terminal 7 of the coil block 6 is connected to the female terminal of the terminal block 8. 14 is engaged. Further, the lead wire 16 connected to this female terminal 14 is inserted into the communicating hollow part of the terminal block 8, and the terminal of the common terminal connector 21 attached to one end of the connected terminal block 8 is inserted.

The rear holding plate 20 has a connecting flange 25 on the front surface and a joining protrusion 26 on one side.

As shown in FIG. 2, the plurality of terminal block blocks 8 arranged and bonded to one side of the manifold base 1 as described above fit the bonding protrusion 24 of the front pressing plate 19 into the bonding groove 3 at the frontmost end thereof. At the same time, by fitting the joint protrusion 26 of the rear presser plate 20 into the joint groove 3 at the rearmost end and fixing it with the fixing screw (not shown), the manifold base is fixed. It is fixed to one side of 1 without sliding back and forth. The connecting protrusion 25 of the rear presser plate 20 is fitted into the rear opening of the terminal block 6 at the rearmost end with an O-ring 28 fitted to its outer peripheral surface.

The male terminal connector 21 has a large number of male terminals 2.

As detailed above, the present invention has the following effects.

Prepare a hollow terminal block that corresponds to the coil block of the valve body, connect and attach it detachably to the side of the manifold base instead of on the valve body, and after wiring the terminal block, connect the terminal block to the valve body. When placing the coil blocks on the manifold base, all the coil blocks are connected to the connected terminals by simply engaging the male terminals protruding from the bottom of the coil blocks with the female terminals provided on the top of the terminal block. Wiring can be connected to the outside all at once using one common terminal connector at one end of the stand block, so when increasing or decreasing the number of valve bodies, it is not necessary to attach/remove the lead wire box and rewire as in the past. Also, the valve body is extremely easy to attach and detach.

The terminal block can be assembled by removably fitting its joint protrusion into a horizontally long joint groove formed on the almost vertical side of the manifold base.
The lead wire box is attached to the manifold base, and the lead wire box is bolted to the top surface of each valve body in order to connect the hollow part by removably fitting the connecting flange and the opening. It is also easier to assemble than the conventional method, which connects them with bolts and nuts.

The terminal block is installed along the side of the manifold base and fits into the space below the coil block, making the whole valve more compact than in the past, where the lead wire box protrudes above the valve body. This also eliminates the need for extra installation space.
