Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a manibold type solenoid valve device in which a coil valve is installed on one side or both sides of a valve body.

Conventionally, for electrical wiring in this type of solenoid valve device,
Generally, a separate socket was attached to the outside of each coil block of the valve body, and the cords were pulled out separately for each valve body, so a large number of cords were distributed and pulled out to the sides of the valve body, resulting in electrical wiring. The drawback was that it required a lot of space and was prone to wiring errors.

Therefore, in the past, one end of the lead wire was connected to each coil block, the other end was connected to a common terminal wiring board, and another lead wire for power connection was drawn out from this terminal wiring board through the wiring extraction hole. things are provided.

An object of the present invention is to provide a solenoid valve device that is easier to rewire when increasing or decreasing the number of valve bodies and easier to maintain than the conventional solenoid valve device.

According to the present invention, this purpose is to form a joining groove on one or both sides of the manifold base, while forming a terminal block corresponding to each coil block with a female terminal on the top surface and a joining protrusion on the side surface. The terminal block is arranged and connected to the side surface of the manifold base by fitting the joint protrusion into the joint groove removably from one end thereof, and also connects the terminal block to the side surface of the manifold base. This is accomplished by removably fitting the terminal into the two female terminals and electrically connecting the lead wire drawn out from the female terminal of the terminal block to the terminal of the common terminal connector.

Next, one embodiment of the present invention will be described in detail based on the drawings.

As shown in Fig. 1, the manifold base 1 has a size that allows multiple valve bodies 2 to be placed in parallel, and a joint/IJ (dovetail groove) 3 with a trapezoidal cross section is formed along the entire length of the side surface thereof. There is.

Each valve body 2 is attached to the manifold base 1 by two mounting screws 4 via a seal plate 5, and a coil block 6 is attached to the lower side of each valve body 2. Two male terminals 7 are provided protruding from the lower surface of each coil block 6.

Terminal block blocks 8 are prepared in correspondence with the coil blocks 6, respectively. The terminal block 8 has a rectangular box shape as shown in FIG. A connecting flange 11 is provided around the connecting flange 11, and a joining protrusion 12 having a trapezoidal cross section is protruded from one side perpendicular to the connecting flange 11. A socket 13 is provided in each terminal block 8. Sokaso eyes 3 is 1
A pair of female terminals 14 are buried therein, and a locking groove 15 is formed all around the circumferential surface. Lead wires 16 are connected to the female terminals 14, respectively.

The socket 13 is attached to the terminal block block 8 by passing the lead wire 16 from the socket mounting hole 9 to the lead wire extraction hole 1o and forcibly fitting the locking groove 15 to the edge of the socket mounting hole 9. .

Further, the terminal block block 8 sequentially fits the joint protrusion 12 into the joint groove 3 of the manifold base 1 from one end of the terminal block 8 in a detachable manner, and connects the connecting flange 11 to the joint groove 3 of the manifold base 1. By fitting into the rear opening, it is aligned and joined to one side of the manifold base 1.

In order to seal the inside of the terminal block block 8 airtightly or liquid-tightly, a gasket 17 is interposed between the socket head 3 and the terminal block block 8, and an O-ring 18 is installed on the outer peripheral surface of the connecting flange 11. Insert.

This solenoid valve device further includes front and rear holding plates 19°20,
Mf: terminal connector 21 and t[1] terminal connector 22 are prepared. The front and rear pressing plates 19 form a lead wire insertion opening 23 and have a joining protrusion 24 protruding from the negative side. The rear holding plate 20 has a connecting flange 25 on the front surface and a joining protrusion 26 on the side surface.

As shown in FIG. 2, the plurality of terminal block tabs 2 8 arranged and bonded to one side of the manifold base 1 as described above connect the connecting protrusion 24 of the front presser 1 19 at their frontmost ends. It is fitted into the groove 3 and fixed with a fixing screw 27, and at the rearmost end, the joint protrusion 26 of the rear presser plate 20 is fitted into the joint groove 3 and fixed with a fixing screw (not shown). As a result, it is fixed to one side of the manifold base 1 without sliding back and forth. In addition, the rear slope.

The connecting protrusion 25 of 20 is fitted into the rear opening of the rearmost terminal block 6 with an O-ring 28 fitted to its outer peripheral surface.

The male terminal connector 21 has a large number of male terminals 29, and the female terminal connector 22 has the same number of female terminals 30. The lead wire 16 drawn out from the terminal block block 8 is connected to the male terminal 29 by screwing its tip, for example, and is connected to both terminal connectors 2.
L22 is attached to the front surface of the front pressing plate 19 with the mounting screw 31 with the male terminal 29 and female terminal 30 fitted together. A lead wire 32 for external wiring is connected to the female terminal 30.

Therefore, the number of terminal block blocks 8 corresponding to the number of coil blocks 6 is joined to the manifold base 1, the male terminals 7 of the coil blocks 6 are inserted into the female terminals 14 of the socket 13, and the tips of the lead wires 16 are connected to the manifold base 1. Connect to the male terminal 29 of the male connector 21, and also connect both terminal connectors 2'l
, 22 to the front holding plate 19,
The wiring work is completed, and rewiring work is particularly easy when increasing or decreasing the number of valve bodies 2. In addition, all the lead wires 16 are housed and protected within the terminal block 8, and external wiring is carried out collectively through both terminal connectors 21 and 22 at the front end, so there are fewer troubles regarding wiring.

In addition, for a double solenoid type solenoid valve device in which coil blocks 6 are installed on both the left and right sides of the valve body 2, it is possible to use a joint.
R3 may be formed on both sides of the manifold base 1, and the terminal block block 8 may be joined to both sides.

As described above, the present invention has jjL terminals protruding from the lower surface of the coil block, female terminals are provided on the upper surface of the terminal block that is separate from the coil block, and this terminal block is attached to the side of the manifold base. By having a structure that can be joined detachably, and by adjusting the number of parts to be joined according to the number of coil blocks, it is possible to wire an appropriate number of valve bodies at once. It is easy to rewire when increasing or decreasing the number, and maintenance is also easy.
