Description

[Detailed description of the invention] (Field of industrial application) This invention relates to an assembly structure for an equipment case that allows boxes and connecting parts installed deep inside the equipment case to be taken out from the front side.

(Prior art) When equipment cases are mounted on racks stacked in multiple stacks, or when the equipment case itself is quite large and placed in a corner of a room or in a narrow space, the equipment can only be accessed from the front side. Equipment maintenance such as inspection and repair may not be possible from the rear side.

In such cases, conventionally, as shown in FIGS. 3 and 4, the equipment is made up of several units 15, each of which can be pulled out from the front part 16 of the equipment case 1, and each unit is After pulling it out, there was one that allowed maintenance such as inspection and repair to be performed.

(Problems to be Solved by the Invention) In the conventional technology, as shown in FIG. 4, the connections between the units 15 or It was designed to allow connections to external devices.

At this time, the terminal 18 is attached to the rear surface 19 of the device, and a connection cable 20 for connecting to the outside of the device is connected to the terminal 18. Therefore, even if the unit 15 is pulled out to the front side, the terminals 18 and connection cables 20 remain on the rear side. In this state, if maintenance cannot be performed from the rear side of the device as described above, it is extremely difficult to perform maintenance such as inspection and repair of these terminals 18 and connection cables 20.

(Means for solving the problem) The assembly structure of the equipment case according to this invention is the first
As shown in the figure, equipment case 1 and equipment case 1
It consists of a box 2 mounted deep inside the box 2, a terminal mounting plate 5 mounted on the rear side of the equipment case 1 of the box 2, and a terminal 4 mounted on the terminal mounting plate 5.

Further, as shown in FIG. 2, a hole 13 is provided in the rear surface 12 of the device case 1 so that the terminal 4 can pass through the device case 1 together with the terminal mounting plate 5.

(Function) Remove box 2 from equipment case 1,
When the device case 1 is pulled out to the outside of the front surface, the terminal connection plate 5 and the terminals 4 are also pulled out together with the box 2.

When the connection cable 7 is connected to the terminal 4, the connection cable 7 is also pulled out together.

In this way, the parts attached or connected to the rear side of the equipment case 1 are pulled out together with the box 2 into a wide space outside the front of the equipment case 1, so even if maintenance cannot be performed from the rear side of the equipment, it is possible to Maintenance such as inspection and repair of side parts can be easily performed.

(Example) This invention will be explained in detail based on an example of this invention shown in FIGS. 1 and 2.

Deep inside the device case 1, a box 2 made of metal, for example, having a shielding effect is attached from the inside of the case 1 with screws 3. The terminal 4 is attached to a terminal attachment plate 5, and the terminal attachment plate 5 is attached to the box 2 with screws 6. A connecting connector 8 is attached to the tip of the connecting cable 7, and a connecting portion 9 of the connecting connector 8 is connected to the terminal 4.
is inserted inside. The rear surface 12 of the device case 1 is provided with holes 13 through which the terminals 4, the connecting connectors 8 and the connecting cables 7 can pass.

When removing Box 2 from device case 1,
First, remove the screws 10 and remove the front panel 11.
Next, by removing the screws 3, the box 2 can be separated from the equipment case 1 and pulled out to the outside of the front of the equipment case 1.

When the box 2 is pulled out, the connection cable that has passed through the hole 13 is also pulled out to the front side while remaining attached to the box 2, as shown in FIG.

In this way, the terminals 4, the connecting connectors, and the connecting cables 7 are also drawn out to a wide space outside the front of the device case 1, so that it is easy to check the connection state between the connecting connectors 8 and the terminals 4, and whether there is any abnormality in the connecting cables.

When maintaining the inside of the box 2, remove the screws 6 and remove the terminal mounting plate 5. In this way, the terminal 4 and the printed circuit board 14 installed inside the box 2
It will be possible to check whether there are any abnormalities such as

Also, this box 2 is connected to the internal printed circuit board 1.
4, it also has an electromagnetic shielding effect and a thermal shielding effect, and there is no need to provide a special shielding mechanism even when handling weak signals.

(Effect of the invention) According to this invention, parts attached or connected to the rear side of the equipment case are pulled out to a wide space outside the front of the equipment case together with the box installed deep inside the equipment case. . Therefore, even if maintenance such as inspection or repair cannot be performed from the rear side of the equipment, it is not possible to perform maintenance such as inspection or repair from the rear side of the equipment, not only the box and the parts stored inside the box, but also the parts attached or connected to the rear side of the equipment case. Maintenance such as inspection and repair can be performed easily, and work efficiency during maintenance, inspection, and repair can be improved.Furthermore, the box can also be used as a shield mechanism, which is remarkable in practical use. Effects can be obtained.
