[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power supply box mounting mechanism for a manifold valve.

[0002]

2. Description of the Related Art In a manifold valve having a large number of solenoid valves connected to a manifold in order to control a large number of fluid pressure devices at a time, a power supply box for collectively supplying power to these solenoid valves is provided with a manifold. The one fixedly attached to one end of the device is already known without particular examples. However, the user of the manifold valve does not always need the power supply box, and therefore, it is desired that the user can easily attach and detach the power supply box.

[0003]

A problem to be solved by the present invention is to provide a manifold valve that allows a power supply box to be attached to and detached from an end plate by a simple operation.

[0004]

In order to solve the above-mentioned problems, a power supply box mounting mechanism for a manifold valve according to the present invention includes a manifold having a number of solenoid valves connected in series and end plates mounted on both ends of the manifold. In the provided manifold valve, the end plate has a pair of legs for fixing the manifold valve,
An inverted L-shaped guide groove formed to face these legs, and a power supply box attached to one of the end plates has a guide projection inserted into the guide groove;
A power supply box mounting surface of the end plate, an engaging protrusion is provided on one of a contact surface that abuts the mounting surface of the power supply box, and an insertion hole into which the engaging protrusion is inserted, and An engaging groove, which is continuous with the insertion hole and is engaged with the engaging projection by a relative movement between the mounting surface and the contact surface, is provided. Further, in order to solve the same problem, in the power supply box mounting mechanism for the manifold valve, the locking recess is provided on the mounting surface of the end plate. A locking member having a locking portion that locks to prevent relative movement with the end plate is provided.

[0005]

When the guide protrusion of the power supply box is inserted into the inverted L-shaped guide groove provided on the pair of legs of the end plate and the power supply box is pressed toward the end plate, the contact surface of the power supply box is brought to an end. The abutment comes into contact with the mounting surface of the plate, and the engagement protrusion is inserted into the insertion hole. When the end plate and the power supply box are relatively moved in the direction orthogonal to the pressing direction in this state, the engagement protrusions engage with the engagement grooves continuous with the insertion holes. The power box can be removed by the opposite operation. The power supply box can be attached and detached while the manifold valve is attached to a required member by the legs, so that the power supply box can be easily attached to and detached from the manifold valve.

[0006] Further, since the locking portion of the locking member attached to the power supply box is elastically locked in the locking recess of the end plate, relative movement between the power supply box and the end plate can be prevented.

[0007]

The manifold bases 2 are provided with a supply passage and a discharge passage (both not shown) for compressed air which are connected to each other by being connected to each other. A so-called one-touch fitting 7,... Is attached to the supply port and the discharge port which are opened, respectively, and to the supply port and the discharge port, and the output port opened on the front face of each manifold base 2.

The solenoid valve 3 communicates between the supply port and one output port and the other output port and the discharge port by excitation of the solenoid, and when the excitation of the solenoid is released, the supply port, the other output port and the one output port. And a discharge port communicating with a well-known 5-port solenoid valve. However, the solenoid valve 3 of the present invention is not limited to the 5-port valve. Each of these ports communicates with a corresponding supply flow path, discharge flow path, and output port through an opening formed in the valve installation surface of the manifold base 2, and each solenoid is connected to the manifold base 2,. Are individually connected to the pins of the multi-pole connector 8.

The end cover 4 has legs 10, 10 for fixing a manifold valve, and mounting bolts (both of which are attached to these legs 10, 10) for attaching the manifold valve to an appropriate member. (Not shown) and the like, and inverted L-shaped guide grooves 12, 12 for guiding the movement of the power supply box 5, are formed on the mounting surface 4a on which the power supply box 5 is mounted. An engaging projection 13 having an enlarged diameter portion, a locking concave portion 14, and an opening 15 for passing the multipolar connector 8 are formed therein (see FIG. 1).

The power supply box 5 has guide projections 17, 17 fitted into the guide grooves 12, 12 at the lower portion of the side surface, and the engaging projection 13 inserted above the contact surface 5a with the end cover 4. And an engaging groove 19 having a reduced diameter and an opening that is continuous with the insertion hole 18 and engages with the enlarged diameter portion of the engaging projection 13.
An opening 20 (see FIG. 2) into which the other pole connector 8 is inserted is provided below the corresponding contact surface 5, and the opposite locking member 6 is provided on the lower surface.
Mounting portions 21 and 21 and notch portions 22 between these mounting portions.
(See FIG. 4).
The connector 24 electrically connected to the terminals 23 is attached at a position facing the opening 20.

The locking member 6 shown in detail in FIG. 4 is formed by bending a wire having appropriate strength and elasticity, such as steel wire, into a substantially U-shape. The engaging portion 25 is slidably inserted, and is engaged with the engaging concave portion 14 at one end protruding from the contact surface 5a, and is engaged with one of the mounting portions 21 at the other end. Each of the bent portions 26 for preventing the power supply box 5 from slipping out is formed. Reference numeral 28 in the drawing denotes a cover attached to the end plate 4.

Next, the operation of mounting the power supply box 5 in the above embodiment will be described with reference to FIGS.
Before mounting the power supply box 5, the multi-pole connector 8 is connected to the connector 24 through the opening 20. Next, the guide projections 17, 17 of the power supply box 5 are fitted into the guide grooves 12, 12 of the end plate 4 and pressed toward the mounting surface 4a of the end plate 4 (see FIGS. 3 and 4). Abuts against the mounting surface 4a, and the engaging projection 13 is inserted into the insertion hole 18. In this case, the locking portion 25 of the locking member 6 is on the contact surface 5a by contact with the mounting surface 4a (see FIGS. 5 and 6). When the power supply box 5 is pressed downward along the guide grooves 12, 12, the enlarged diameter portion of the engagement protrusion 13 engages with the engagement groove 19 continuous with the insertion hole 18 and the locking member 6. Of the power supply box 5 is attached to the end plate 4 (FIGS. 7 and 8).
