Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a manifold solenoid valve device used for various control devices using a large number of solenoid valves.

[Prior Art] Conventionally, as a manifold solenoid valve device of this type, for example, the one disclosed in Japanese Utility Model Laid-Open No. 61-114180 has a sixth aspect.
As shown in the drawing, an electric connector is provided on the manifold mounting surface of each solenoid valve 1, and this electric connector is connected to the electric connector 3 provided on the upper side of the manifold 2 to attach each solenoid valve 1 to the manifold 2. . However, in this method, when mounting the solenoid valve 1 on the manifold 2, it is difficult to confirm the positional relationship between the electrical connector on the solenoid valve 1 side and the electrical connector 3 on the manifold 2 side. There is a drawback that it costs.

Further, when the solenoid valve 1 is attached or detached for maintenance or the like, the solenoid valve 1 and the manifold 2 are simply fixed between the electrical connectors when the mounting screws of the solenoid valve 1 are removed. In this state, if an undesired external force is applied to the solenoid valve 1, there is a drawback that the electric connector is apt to be damaged or broken. In particular, when the small solenoid valve 1 having a small electric connector is used, the danger is great.

[Object of the Invention] The object of the present invention is to improve the drawbacks of the conventional example, to easily and quickly connect the electrical connectors to each other when the solenoid valve is attached to the manifold, and to perform maintenance and inspection. An object of the present invention is to provide a manifold solenoid valve device that is free from the risk of damaging or breaking the electrical connector portion.

[Summary of the Invention] The gist of the present invention for achieving the above-mentioned object is to provide a solenoid valve connector portion projecting below a plurality of solenoid valves mounted on a manifold, and to provide the solenoid valve connector portion on the manifold side. In the manifold solenoid valve device configured to be coupled to the manifold connector section, the manifold has a manifold body having the manifold connector section arranged on one side, manifold side covers attached on both left and right sides thereof, and a space between these manifold side covers. And a guide groove formed between the manifold connector portion and the guide cover, the solenoid valve protruding downward longer than each solenoid valve connector portion, and the guide groove. A protrusion having a width corresponding to the groove width of the The manifold solenoid valve device is mounted on the manifold in a state of being fitted in the guide groove.

[Embodiment of the Invention] The present invention will be described in detail based on the embodiment shown in FIGS. 1 to 5.

FIG. 1 shows the first embodiment, and FIG. 2 shows the disassembled state before assembly. The solenoid valve body 11 is fixed to the manifold body 13 with mounting screws 12, a plurality of manifold connector parts 14 are mounted on the front side of the manifold body 13, and manifold side covers 15a and 15b are mounted on the left and right sides respectively. Connected by 16. These manifold side covers 15a, 15b
Has terminals for receiving electric signals for driving the solenoid valve main body 11 from the common ports and the outside and energizing each manifold connector section 14. Also, on the front surface of these manifold side covers 15a, 15b, the guide surface 17a
A guide cover 17 having a groove is attached by a mounting screw 18, and the guide surface 14a which is the front surface of the manifold connector portion 14 and the guide surface 17a inside the guide cover 17 form a guide groove 19 having a considerably large groove width. ing. On the other hand, the solenoid valve connector portion 20 is projected on the manifold mounting surface of the lower surface of each solenoid valve main body 11, and the positioning projection portion 21 fitted in the guide groove 19 is located lower than the solenoid valve connector portion 20. Is projected to. This protrusion 21
The front surface 21a and the rear surface 21b are guide surfaces when they are inserted into the guide groove 19, and the interval between them is slightly smaller than the width of the guide groove 19.

A manifold configured by combining the manifold body 13, the manifold connector portion 14, the manifold side covers 15a and 15b, and the guide cover 17 in the above configuration.
When the solenoid valve main body 11 is attached to the manifold 22, the positioning is naturally determined by fitting the projection 21 of each solenoid valve main body 11 into the guide groove 19, so that the manifold connector
It is possible to quickly and easily connect 14 and the solenoid valve connector portion 20.

In addition, at the time of maintenance and inspection, even when the mounting screw 12 is removed, the protruding portion 21 fits into the guide groove 19 and the solenoid valve main body 11 can maintain a stable state. Even if an external force is applied unintentionally, the connector parts 14 and 20 will not be damaged or broken. Although only one solenoid valve main body 11 attached to the manifold 22 is shown in the drawing, it goes without saying that a plurality of similar solenoid valve main bodies 1 can be similarly attached.

3 and 4 show an embodiment in which the present invention is applied to a solenoid valve for serial / parallel transmission. Here, a control circuit housing case 23a for housing a control circuit for receiving a solenoid valve control signal from the outside is shown. , 23b are attached to the manifold side covers 15a, 15b, respectively, and an electric circuit such as a conversion circuit for converting a serial control signal into a parallel control signal is provided in the internal space of the protruding portion 21 protruding downward of the solenoid valve main body 11. It shows the case of incorporating. If a plurality of solenoid valve main bodies 11 are connected to each other and a serial / parallel transmission solenoid valve that has a complicated electric circuit and is hard to find a broken portion is constructed as shown in FIGS. 3 and 4, a large number of solenoid valve main bodies 11 can be formed. It is possible to greatly reduce the number of installation steps and time, and the electrical connector section 14,
This is especially effective because 20 failures can be reduced.

FIG. 5 shows still another embodiment. In this case, in order to prevent each solenoid valve body 11 from shifting in the left-right direction, an example in which a positioning special projection 17b is provided on the guide surface 17a of the guide cover 17 is shown. Shows. Of course, such a protrusion 17b can also be provided on the guide surface 14a on the manifold connector portion 14 side. In the case of the embodiment shown in FIG. 5, the position of the protruding portion 21 of the solenoid valve body 11 is restricted in any of front, rear, left and right directions.
More accurate positioning is possible, and the mounting screws
Even when 12 is removed, it becomes more stable against external force.

In each of the above embodiments, the protrusion 21 of each solenoid valve body 11
The case where the guide groove 19 for fitting with is formed by the one surface of the manifold connector portion 14 and the guide cover 17 has been shown, but this guide groove 19 may be a recess for fitting the projecting portion 21 of the solenoid valve main body 11. . The protrusion 21 of the solenoid valve body 11 may be integrated with the solenoid valve body 11 or may be provided on another pedestal to which the solenoid valve body 11 is attached.

[Advantages of the Invention] As described above, in the manifold solenoid valve device according to the present invention, a protrusion longer than the connector is formed below each solenoid valve body so that it can be fitted in the recess provided on the manifold side. When attaching the solenoid valve, it is possible to easily and quickly connect the solenoid valve side and the manifold side electric connectors. Also, at the time of maintenance and inspection,
Even when the solenoid valve mounting screws are removed, the solenoid valve can be held stably, so there is a risk of untimely external force being applied to the solenoid valve, damaging the electrical connector, and causing a wire breakage accident. There is also the advantage of not having it.
