DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a solenoid valve terminal block for connecting a lead wire of a solenoid valve mounted on a manifold block and a lead wire for a power source thereof, and in particular, The present invention relates to a technique effectively applied to a solenoid valve terminal block installed in a manifold block.

[Conventional technology]

For example, as a terminal block for a solenoid valve installed in a manifold block, a support base fixed to the manifold block, a lead wire for the solenoid valve and a lead wire from an external power source that are detachably attached to the support base. There is a structure provided with a terminal block body for connecting (for example,
Jpn.

In this solenoid valve terminal block, the terminal block body is removably attached to the support block, so after removing the terminal block body from the support block, the lead wire connection and The structure allows for removal work.

[Problems to be Solved by the Invention] In the electromagnetic flight terminal block described above, the lead wire on the solenoid valve side remains fastened to the terminal block body even if the terminal block body is removed from the support block. Therefore, the movable range of the terminal block body is restricted by the length of the lead wire on the solenoid valve side.

Therefore, it may be difficult to carry out the wiring work in a work space with a lot of space.

Therefore, as a terminal block for a solenoid valve that solves such a problem, for example, a connector that is connected to the manifold main body and the terminal block main body is arranged, and the fastening screw of the wiring cover for the terminal block main body is connected to the terminal. It is conceivable that the terminal block body is attached to the manifold block by loosely penetrating it into the free hole of the base body and screwing its tip into the screw hole of the manifold block.

However, such a mounting structure using a fastening screw requires a screwing operation of the fastening screw when the terminal body is attached and detached, and therefore, improvement in workability of wiring is hindered.

An object of the present invention is to provide a terminal block for a solenoid valve that can improve wiring work.

The above and other objects and novel features of the present invention are as follows.
It will be apparent from the description of this specification and the accompanying drawings.

That is, the structure of the solenoid valve terminal block of the present invention is a first terminal block fixed to the manifold block side and having an electrical connection portion for connecting the lead wire on the solenoid valve side, and detachable from the first terminal block. A second terminal block mounted on the power supply side and having an electrical connection portion for connecting a lead wire on the power source side, and an elastically deformable wiring cover that detachably covers the second terminal block. The second terminal block is detachably attached to the first terminal block by a pressing force generated by a force, and both electrical connection parts are connected.

[Action]

According to the structure of the solenoid valve terminal block described above, the first terminal block having the electrical connection portion for connecting the lead wire on the solenoid valve side,
Since the second terminal block having the electric connection portion for connecting the lead wire on the power supply side is detachably mounted, the work space is comfortable without being restricted by the length of the lead wire on the solenoid valve side. Wiring work can be performed by moving the second terminal block.

Further, since the second terminal block is detachably attached to the first terminal block by the pressing force of the elastic force of the wiring cover and the electrical connection parts of both are connected, a screwdriver work or the like is required. No, second to first terminal block
The attachment / detachment work of the terminal block can be easily performed, and therefore, also from this point, the wiring work can be facilitated.

[Embodiment] FIG. 1 is a sectional view showing a solenoid valve terminal block according to an embodiment of the present invention, and FIG. 2 is a front view thereof.

The solenoid valve terminal block of this embodiment includes a first terminal block 2 fixed to a manifold block 1 by fastening means.
It has.

A solenoid valve 4 is detachably mounted on the manifold block 1.

The first terminal block 2 has a connector 5 (electrical connection portion) for a lead wire on the solenoid valve 4 side, and this connector 5
Is a terminal portion composed of fastening means for connecting the intermediate lead wire 6.
5A and a contact portion 5B are formed respectively.

The solenoid valve terminal block of this embodiment has a solenoid valve connector 8 that is detachably connected to the connector 7 of the solenoid valve 4, and the intermediate lead wire 6 is connected to this connector 8. And a contact portion (not shown) that comes into contact with a contact portion (not shown) of the connector 7 of the solenoid valve 4 are formed.

The solenoid valve terminal block of the present embodiment includes a second terminal block 9 which is detachably mounted on the manifold block 1 and the first terminal block 2, and a wiring cover which detachably covers the second terminal block 9. It has 10 and.

The second terminal block 9 has a connector 11 (electrical connection part) for connecting a lead wire on the power source side.
A terminal portion 11A composed of fastening means to which a lead wire on the power source side is connected, and a contact portion 11B which comes into contact with the contact portion 5B of the first terminal block 2 are formed on the side.

Further, the second terminal block 9 is formed with a locking portion 13 which is locked to the locking step portion 12 of the manifold block and is elastically deformable in the vertical direction of FIG.

On the other hand, in the wiring cover 10, the space between the pressing portion 10A and the lower opening end 10B locked to the locking portion 1A of the manifold block 1 is reduced by the elastic force of the wiring cover 10 itself. The locking portion 13 of the second terminal block 9 is biased by the elastic force of the wiring cover 10 and is pressed against the locking step portion 12 against the upward biasing force of the elastic force. Thus, the second terminal block 9 is detachably attached to the manifold block 1 and the first terminal block 2, and the contact portions 5B and 11B are in contact with each other and electrically connected.

 Next, the operation of this embodiment will be described.

First, when performing wiring work from the mounted state of the wiring cover 10 shown in FIG. 1 and the like, the wiring cover 10 is displaced in the direction of the broken arrow until it is removed from the locking step portion 12 of the second terminal block 9. Then, the tip end side of the locking portion 10A of the wiring cover 10 is displaced in the direction of the solid line arrow in the figure by the elastic biasing force.

In this way, by removing the wiring cover 10 from the manifold block 1 and the second terminal block 9, the locking portion 13 of the second terminal block 9 is released from the pressing by the pressing portion 10A of the wiring cover 10. The second terminal block 9 is naturally separated from the first terminal block 2 and the manifold block 1.

Of course, the contact between the contact portions 5B and 11B is naturally released.

Therefore, according to the solenoid valve terminal block of the present embodiment, the second terminal block 9 can be removed from the manifold block 1 and the first terminal block only by removing the mounting of the wiring cover 10 from the manifold block 1 and the second terminal block 9. It can be easily removed from the base 2, and the screwing work of the conventional solenoid valve terminal base is unnecessary.

Then, the wiring work can be performed by moving the second terminal block 9 to a work space with a space.

In this case, since the second terminal block 9 is not connected to the lead wire on the side of the solenoid valve 4, the second terminal block 9 is not restricted by the length of the lead wire on the side of the solenoid valve 4, and can be used as a work space with room. It can be moved.

In this way, after the second terminal block 9 is moved to a working space with a space and wiring work is performed, the second terminal block 9 and the wiring cover 10 are attached by the procedure reverse to the above.

That is, after the locking portion 13 of the second terminal block 9 is located on the locking step 12 of the third terminal block 3, the wiring cover 10 covers the second terminal block 9, and the pressing portion 10A locks it. Step 13 Locking step 13
The second terminal block 9 and the wiring cover 10 are mounted as shown in FIG.

Also in this case, the solenoid valve terminal block of the present embodiment can be mounted without the need for screwing work as in the conventional solenoid valve terminal block.

Although the invention made by the inventor has been specifically described based on the embodiments, the invention is not limited to the above-described embodiments of the invention, and various modifications can be made without departing from the scope of the invention. There is no end.
