[0002]

2. Description of the Related Art FIG. 8 shows a conventional solenoid valve manifold. This electromagnetic valve manifold is provided with a plurality of electromagnetic directional control valves 74 and 75 in a direction in which the respective flow paths 71 and 72 extend in an integrated manifold base 73 in which a common air supply flow path 71 and an exhaust flow path 72 are formed. Are connected. Each solenoid directional control valve 74 of the solenoid valve manifold is a double-sided solenoid type having solenoid portions 76 and 77 on both sides thereof. In this solenoid valve manifold, a connector block 79 having a centralized connector 78 is mounted on the front surface parallel to the direction in which the flow paths 71 and 72 extend.

[0003] Both solenoid parts 7 of each electromagnetic directional control valve 74
Each of the power supply lines 80 connected to each of the solenoid portions 76 on the front side of the manifold base 73 is introduced into the connector block 79 in a state of being united into one.

I have.

In this solenoid valve manifold, each power supply line 8 of each solenoid portion 77 on the rear side of the manifold base 73 is provided.
In the environment where the solenoid valve manifold is installed, each power supply line 81 was likely to interfere with surrounding objects because 1 greatly extended to the outside. Also, the appearance was not good.

In order to solve such a problem, the solenoid valves 74 are arranged so as to be spaced apart from each other in the direction in which the supply passage 71 and the exhaust passage 72 extend, and a gap is formed between the solenoid valves 74. There is a solenoid valve manifold that is guided in the gap to the front side of the manifold base 73 through each power supply line 81. Therefore, in this solenoid valve manifold, since each power supply line 81 does not protrude greatly outward,
Each power supply line 81 is less likely to interfere with the surrounding ones.

At the lower front corner of the wiring housing portion 45, a second convex engaging portion 46 having a shape capable of elastically deforming and engaging with the second engaging groove 36 from behind is formed. . The second convex engaging portion 46 is formed in a substantially cylindrical shape. Then, the second convex engagement portion 46 is
Is engaged with the engaging groove 36, the wiring housing portion 45 is
In the notch 35 of FIG.

The third lower part of the front side of the substrate part 44 is
A third convex engaging portion 47 having a shape engaging with the engaging groove 37 is formed. The third convex engaging portion 47 is constituted by a pair of engaging projections 48 formed with a gap. An oblique portion 49 is formed at the tip of each engagement projection 48.

The first wiring cover 29 is held in that state by engaging with the engaging groove 34 of FIG. When the joint adapter 12 is attached to a predetermined position of the manifold base 2 in this state, as shown in FIG. 7, the first wiring cover 29 and the joint adapter 12 serve as a guide passage for passing the power supply line 19B. The first guide passage 56 is formed. This first
After the guide passages 56 are formed, the power supply lines 19B are accommodated in the first guide passages 56. That is, when the power supply line 19 </ b> B is pressed against the opening / closing section 42 of the first wiring cover 29, the opening / closing section 42 is bent toward the substrate section 38 by elastic deformation.

At this time, each tip of both engagement projections 48 of the third convex engagement portion 47 is slightly in the opening of the third engagement groove 37. However, since the third convex engaging portion 47 has not yet engaged with the third engaging groove 37, the substrate portion 44 is elastically deformed, and the lower portion is moved forward. For this reason, the lower plate 57 of the wiring housing portion 45 is elastically deformed, and its front portion curves upward. At this time, assuming that the second convex engaging portion 46 is completely fixed in the second engaging groove 36, the stress generated by the curvature of the substrate portion 44 is concentrated on a specific local portion of the lower plate 47. I do. However, in the present embodiment, since the second convex engaging portion 46 is formed in a columnar shape, it slightly rotates in the second engaging groove 36 with the upward movement of the lower plate 57. as a result,
The stress caused by the curved deformation of the substrate portion 44 is not concentrated on a specific local portion of the lower plate 57.

In this state, when the third convex engaging portion 47 is pressed against the opening of the third engaging groove 37 from the front,
The third convex engaging portion 47 is formed by elastic deformation of the both engaging protrusions 48.
Engage with the third engagement groove 37. In the state where the second convex engaging portion 46 is engaged with the second engaging groove 36 and the third convex engaging portion 47 is engaged with the third engaging groove 37, the second The wiring cover 31 is fixed to the manifold base 2 without rattling.

As described in detail above, according to the first aspect of the present invention, each power supply line connected to each solenoid valve without increasing the size and without using an expensive board or the like. Can be shielded from the outside.

In addition to the above-described effects, the same parts can form the guide passages for the solenoid valve manifolds having different lengths of the manifold base due to the different numbers of the solenoid valves connected in series.

According to the second and third aspects of the present invention, even when the supply / discharge port joint is provided on one side of the manifold base, each power supply line connected to each solenoid valve without using expensive parts. Can be shielded from the outside. In addition, the same components can form the guide passage for the solenoid valve manifolds having different lengths of the manifold base due to the difference in the number of solenoid valves connected in series.
