DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring console for monitoring and controlling various devices in buildings, factories, roads, water treatment plants, and the like, and to a wiring cap for inserting a cable used in the console.

[0002]

2. Description of the Related Art Generally, as shown in FIG. 6, a monitoring console is provided with a top plate 3 in a box 2 of the monitoring console 1, and
The CRT 4 and the keyboard 5 are placed on the top, and the cable 6 of the CRT 4 is introduced into the box 2 through the through hole 7 of the top plate 3,
A heat radiating plate 10 in which a heat radiating slit 9 is formed is provided on a rear plate 8 of the box 2. Then, the heat generated by the units in the box 2, that is, the monitoring and control equipment, is sucked in from the lower part of the front surface of the box 2 by the radiating fan in the box 2 and is discharged from the heat radiating plate 10. The inspection is performed with the back plate 8 removed.

However, in this case, since the heat dissipation and inspection are performed from the back of the control console 1, the control console 1 cannot be brought into close contact with the wall surface. It takes space and takes a lot of space.

In order to effectively use the space, a control console 1 shown in FIG. 7 is conceivable so that the control console 1 can be brought into contact with a wall surface. That is, the cover 11 is screwed into the opening at the rear of the top plate 3.
2 and a slit 9 is formed in the lid 11 for heat dissipation, a handle 13 is attached to the lid 11, the screw 12 is removed by a tool such as a screwdriver, the lid 11 is removed by the handle 13, and the internal equipment is inspected. Do.

A wiring cap 14 for inserting the cable 6 is attached to a cap opening of the top plate 3 on the side of the lid 11. The cap 14 includes a cylindrical lid 15 and a cover 17 that covers the lid 15 except for the cable insertion portion 16.

[0006]

In the case of the control console 1 shown in FIG. 7, the lid 11 serves both for heat dissipation and for inspection.
Since the wiring cap 14 is provided at a position different from the position 1, the structure of the top plate 3 is complicated, and the top plate surface is not united and complicated.

[0007] In addition, when inspecting the internal equipment, the screw 1
A tool such as a screwdriver is required for attaching and detaching the screw 2, and the screw 12 may fall into the box 2 and cause an accident such as a short circuit in the equipment. There is a problem that it is difficult.

In the present invention, the above-mentioned points are taken into consideration, space is saved, the structure of the top plate is simplified to make the surface of the top plate unified, and tools and the like are required for attaching and detaching the lid. In addition, an object of the present invention is to provide a monitoring and control console that reduces the gap between the cable insertion portions due to the number of cables, and a wiring cap used for the control console.

[0009]

According to a first aspect of the present invention, there is provided a monitoring and control console for storing monitoring and control equipment and a heat radiating fan in a box body. Attach a lid for inspection and heat radiation to the opening of the top plate by pressing and fitting, attach it with a retractable locking tool, attach a wiring cap to the lid, and insert a cable of equipment on the top plate, A finger is inserted into the cable insertion opening, and the lid is detached from the top plate against the fitting force of the locking tool by pulling back the finger.

According to the first aspect of the present invention, a lid for inspection and heat radiation is attached to the opening of the top plate of the box body by means of a push-fit, pull-back and detachable locking tool. Therefore, when removing the lid, put the finger in the wiring cap and pull the finger back against the fitting force of the locking tool to remove the lid, when attaching the lid, it is only necessary to press the lid, No tools such as a screwdriver are required to attach / detach the lid, and it is easy to attach / detach.Since screws are not used to attach the lid, the screws do not fall into the box and do not cause an accident such as a short circuit. Since the wiring cap is attached to the lid, the top plate has no opening of the lid and the cap opening of the cap, so that the structure of the top plate is simplified and the top plate surface is united and neat.

Next, the invention according to claim 2 is based on claim 1.
In the invention described above, a cover is provided at a cable insertion opening of the wiring cap so as to move in parallel with the lid to open and close the insertion opening.

Therefore, since the cover for opening and closing the cable insertion port is provided in parallel with the lid, by contacting the tip of the cover with the cable, no gap is generated in the insertion port due to the number of cables, and the cable is inserted into the box body. Dust and foreign matter can be prevented from entering.

Next, a third aspect of the present invention is the second aspect.
In the invention described in the above, the cover for opening and closing the cable insertion port is provided with a spring for urging in a direction to sandwich the insertion port.

Therefore, since the tip of the cover always contacts the cable by the spring, even if the cover moves due to contact, vibration, etc., and a gap is generated between the tip of the cover and the cable, the cover is immediately closed. Abuts on the cable so that there is no gap.

According to a fourth aspect of the present invention, there is provided a wiring cap for use in a monitoring and control console, wherein a peripheral wall fitted to a peripheral edge of a cap opening of the mounting plate and a guide formed on the peripheral wall and parallel to the mounting plate. And a cover that moves along the guide and opens and closes a cable insertion port in the peripheral wall.

In the wiring cap configured as described above, a guide parallel to the mounting plate is formed on a peripheral wall fitted to the peripheral edge of the cap opening of the mounting plate, and a cable insertion port is formed along the guide. Since the cover that opens and closes moves, the distal end of the cover is brought into contact with the cable, thereby preventing a gap from being formed in the insertion port due to the number of cables and preventing dust and foreign matter from entering the attached plate.

Next, the invention according to claim 5 is directed to claim 4
In the invention described in the above, the cover for opening and closing the cable insertion port is provided with a spring for urging in a direction to sandwich the insertion port.

Therefore, since the tip of the cover always contacts the cable by the spring, even if the cover moves due to contact, vibration, or the like, and a gap is created between the tip of the cover and the cable, the cover is immediately turned on. Abuts on the cable so that there is no gap.
