The present invention relates to a cabinet structure of a child device. 2. Description of the Related Art Referring to FIGS.
A conventional cabinet structure will be described. Cabinet
Is composed of a cabinet body 1 and a front cover 2.
The cabinet body 1 has a front opening on the front side.
You. Although not shown, the rear surface of the cabinet body 1
Backboard with multiple connectors attached to the side
Electronic parts such as ICs and LSIs on printed wiring boards
The electronic circuit package on which the product is mounted is inserted through the front opening.
Plugged into the backboard connector
You. The front opening of the cabinet body 1 is detachable with the front lid 2.
Closed as possible. In FIGS. 20 and 21, reference numeral 3 denotes another device.
External cable (optical cable) as a line for connection to
And the external cable 3 is on the rear side of the cabinet body 1.
From the front, pulled out to the front side, and the corresponding electronic
Connector to the road package. External cable 3
The extra length is appropriately processed in the cabinet body 1.
Therefore, the external cable 3 is laid on the cabinet body 1.
Space 4 for work (introduction, extra length processing, connection, etc.) is provided
Have been. This space 4 works by inserting human hands
It is as large as possible. [0004] Note that the cabinet book
In some cases, the side of the body 1 is opened and closed. 5 is an outside line
It is a fixing member for fixing the cable 3. Also figure
Although illustration is omitted, near the upper surface of the cabinet body 1
Has a cooling fan for cooling the inside,
An air vent for inhaling outside air is provided on the lower surface of the cabinet body 1.
Are formed. Inside the lower surface of the cabinet body 1
Is formed in a substantially plate shape as shown in FIG.
The air filter 6 is detachably attached. D
A filter 6 is inserted along a pair of rail members 7,
Pressed against the rear stopper provided at the rear
It can be attached and detached by fixing the fixing bracket 8 with screws.
Noh is attached to the cabinet body 1. [0005] The cabinet constructed as described above is
With a universal rack (general purpose rack)
May be attached (mounted) to the
23, both sides of the cabinet body 1
Each part has a plurality of screw holes 1a formed therein,

Is fixed. [0006] The cabinet is a universal rack
Is mounted via rack mounting ears 9
If not mounted on a universal rack, install the rack
9 has been removed. When the rack mounting ears 9 are removed
In some cases, a hole-hiding screw may be screwed into the screw hole.
You. [0007] However, according to the prior art,
Then, there were the following problems. (1) Laying of external cable (introduction, extra length processing, connection, etc.)
About to secure space for work as described above
This space is required for cable laying and connection work.
Not required after work, so electronic devices can be made smaller and densely packed
It is an obstacle to the development. The side of the cabinet body
The cabinet is designed to open and close.
-It becomes difficult or impossible to work after mounting on sal rack
May not be valid. In addition, these laying works
The work was extremely complicated. (2) The air filter is detached for replacement or cleaning.
However, in the past, was the structure used to fix the fixtures with screws?
Therefore, the attaching / detaching work was complicated. (3) The cabinet is mounted on a universal rack
May or may not be mounted.
If the rack mounting ears are removed when the
You can see the screw hole or the screw for concealing the hole,
Damaged and lost rack mounting ears
Can be mounted later on a universal rack.
There was a problem that it might not be possible. Accordingly, an object of the present invention is to provide an external cable
The purpose is to improve the workability of installation work and to reduce the size of the equipment.
You. Another object of the present invention is to simplify the work of attaching and detaching the air filter.
It is to make. Still another object of the present invention is to
An object of the present invention is to prevent loss of ears and improve aesthetics. [0009] The present invention is disclosed in the present application.
