Description

[Detailed Description of the Invention] Industrial Field of Application In the present invention, a pin terminal is embedded in the bottom of a recess formed in the casing of the coil part, and a plug electrically connected to a power source is inserted into the pin terminal. In particular, the present invention relates to a wiring connection device for a solenoid valve to which electricity is supplied from the outside.

Prior Art A solenoid valve includes a terminal portion for supplying electricity from the outside to its coil portion. As an example of the structure of the terminal part, one is known that includes a recess formed in the casing of the coil part and a pin terminal implanted in the bottom surface of the recess.

In addition, there is a demand for adding accessories such as indicator lights and surge absorbers to solenoid valves.
Conventionally, in order to meet this requirement, an indicator light or the like was attached to a terminal block attached to the terminal section of the coil section. At this time, in the case of an indicator light, the lead wire was connected to the wiring of the coil part by soldering or the like, and the indicator light was turned on in synchronization with the energization of the solenoid valve.

Problems to be Solved by the Invention However, when attempting to attach accessories such as indicator lights and surge absorbers to the solenoid valve, work such as wiring and assembly is required. In addition, check the indicator lights,
There was also the problem that repairs, replacements, etc. were time-consuming.

It is an object of the present invention to provide a wiring connection device for a solenoid valve that alleviates the above-mentioned conventional problems and allows easy attachment of accessories.

Means for Solving the Problems The configuration of the present invention for solving the above problems is as follows.

A pin terminal is implanted in the bottom of the recess formed in the casing of the coil part, and by inserting a plug electrically connected to the power source into the pin terminal,
In a wiring connection device for a solenoid valve to which electricity is supplied from the outside, an insertion part that reaches the recess from the outside into the casing and allows a connector of an accessory such as an indicator light to be inserted from a direction different from the insertion direction of the pin terminal. A wiring connection device for a solenoid valve, wherein the insertion portion is formed at a position where the inserted connector comes into contact with the pin terminal.

Operation According to the above configuration, electrical connection can be made to the pin terminal of the coil part by simply inserting the connector of an accessory such as an indicator light from the insertion part, and moreover, simply by inserting the connector of the accessory. , its operation is also extremely simple.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 indicates a solenoid valve, and the solenoid valve 1 is composed of a coil portion 2 and a valve portion 3.
As shown in FIGS. 1 and 2, the coil portion 2 is provided with a terminal portion 4 at one end thereof, and the terminal portion 4 is provided in a recess 5 formed in the casing 2a of the coil portion 2.
and a pin terminal 6 implanted in the bottom surface 5a of the recess 5.
It has

The recess 5 has a rectangular shape when viewed from the plane (direction of arrow A in FIG. 2), and its depth is equal to the depth of the recess formed in the casing 2a itself. Support frame 7
The height of is equal to the added length. Support frame 7
is formed so that the upper outer surface in FIG. 2 is on the same plane as the upper outer surface of the casing 2a. Further, the two pin terminals 6 are arranged at a predetermined interval and are electrically connected to the electromagnetic coil 8.

In the coil portion 2 of the electromagnetic valve 1 thus configured, the insertion portion 10 of the terminal block 9 is inserted into the recess 5 from the direction of arrow A. As shown in FIG. 2, the pin terminal 6 is fitted into the female contact 11 disposed within the insertion portion 10 to provide external electrical wiring.

The configuration described so far is almost the same as the conventional one, and in the past, when attaching accessories such as indicator lights to the solenoid valve with this configuration, they were attached by wiring to the terminal block 9, which caused various problems. I explained that earlier. Therefore, the solenoid valve wiring connection device according to the present invention takes the following measures.

1 and 2, the casing 2a of the coil portion 2 is formed with an insertion hole 12 that penetrates from the outside and reaches the recess 5, and this insertion hole 12 is shown in FIG. The female connector 15 of the indicator light unit 13 shown is formed in a size that can be inserted. The insertion hole 12 is provided at a position where, when the female connector 15 of the indicator light unit 13 is inserted, the female connector 15 is connected to the two pin terminals 6 near the bottom surface 5a of the recess 5. .

An example of the use of the solenoid valve of the present invention in the wiring connection device constructed as described above will be described with reference to FIG.

In Fig. 3, the female connector 15 of the indicator light unit 13 as an accessory is inserted into the insertion hole 1 from the direction of arrow B.
2, the pin terminal 6 is engaged with the connection groove 16. Then, by supporting the indicator light unit 11 on the coil portion 2 with a cover 14 made of a translucent material, the solenoid valve 1 with an indicator light is obtained.

In this way, the indicator light unit 13 can be electrically connected via the pin terminal 6 by only a simple operation, that is, a manual operation of inserting the female connector 15 into the insertion hole 12. In this case, since the insertion hole 12 is near the bottom surface 5a of the recess 5, the female connector 15 is also inserted near the lower end of the pin terminal 6, and the insertion direction is
This is the direction of the arrow B, which is different from the direction A of 0. Therefore,
Even when the insertion portion 10 of the terminal block is inserted as shown in FIG. 2, there is no possibility that the insertion of the indicator light unit 13 will be hindered.

FIG. 4 is a perspective view showing another embodiment of the present invention. In this example, an insertion portion configured as an insertion groove 17 is formed. In this case, the insertion groove 17
extends in the axial direction of the pin terminal 6 and is attached to the bottom surface 5 of the recess 5.
It reaches the tip of the support frame 7 from near a.

The wiring connection device for a solenoid valve constructed in this manner also provides the same effects as those of the embodiments described above.

Although preferred embodiments of the present invention have been described above, the present invention is not limited to the above embodiments and can be modified in various ways. For example, it is most preferable to provide the insertion portion on one surface of the coil part as in the above embodiment, but it may be provided on other surfaces as necessary, or in two locations, one on one surface and the other. It is also possible to provide more than one and electrically connect them to different accessories at the same time. Further, the insertion portion can be formed into an appropriate shape corresponding to the shape of the connector to be inserted.

Effects According to the above configuration, the present invention has a recess in which a pin terminal into which a plug electrically connected to a power supply is inserted is installed, and an insertion part that reaches from the outside of the casing into the recess. Accessories such as lights can be electrically connected to the pin terminal by inserting them from a direction different from the insertion direction of the plug. Therefore, wiring for accessories, assembly work, etc. are not necessary. Furthermore, since the accessory can be electrically connected to the pin terminal simply by inserting the connector of the accessory into the insertion portion, the connection operation is also extremely simple.
