Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to the structure of a casing in which electronic equipment such as communication equipment is housed.

(Prior Art) In a case in which an electronic device such as a communication device is housed, it is necessary to provide a ventilation hole in order to maintain the inside of the case at a predetermined temperature or lower.

FIGS. 7 and 8 show conventional casings of this type.

In the figure, 1 is the main body of the casing, and 2 is the door. The door 2 has a frame 3
and a plurality of inclined plates 4 attached in parallel to this frame part 3.
As a result, it is formed in the shape of an armor plate, and ventilation is performed from between the inclined plates 4.

According to this conventional structure, it is necessary to fix each inclined plate 4 one by one using wood screws, explosive welding, etc., and installation of the inclined plate 4 is complicated. Furthermore, when the door 2 is opened for maintenance, inspection, etc., the tip 5 of the inclined plate 4 protrudes toward the worker, which not only makes the worker feel uncomfortable but also causes physical discomfort during the work. In some cases, it may have caused damage. Furthermore, if the position of the ventilation hole 6 is changed depending on the user's needs, for example, when the case 1A is cooled by forced air cooling with the fan 7 as shown in FIG. It is necessary to provide a ventilation hole so that outside air is taken in from the lower part of the main body 1A of the casing and exhausted from the upper part of the main body 1A. In such a case, it is necessary to remove some of the inclined plates 4 and plug the holes with flat plates instead, but in the case of cases such as communication equipment, multiple cases of the same shape are lined up in a row. In many cases, multiple enclosures are installed with uneven appearance,
In terms of appearance, it could not be said to be good.

On the other hand, as shown in FIGS. 10 and 11, there is also a method of forming the armor plate-shaped ventilation portion 9 by subjecting two sheet metals to bending or the like. According to this method, it is possible to reduce the number of steps required to attach the inclined plates 4 to the frame portion 3 one by one. However, this method has the disadvantage that if one of the inclined plates 4 is damaged, the entire ventilation section 4 must be replaced.

Furthermore, it is necessary to manufacture various types of ventilation sections 9 with different numbers and positions of ventilation holes 6 according to user needs, resulting in high manufacturing costs. Furthermore, the inclined plate 4 is in a state of protruding inward from the housing, which is similar to the housing shown in FIGS. 7 and 8.

(Problems to be Solved by the Invention) As mentioned above, in the case shown in FIGS. 7 and 8, the ventilation portions must be formed by attaching the inclined plates one by one.
Installation of the inclined plate was complicated. Further, when the door is opened, the tip of the inclined plate protrudes toward the operator, which causes the operator to feel uncomfortable. Furthermore, when a plurality of casings with different numbers and positions of ventilation holes are arranged side by side, there is a problem in that the external appearance becomes 1 m shorter. On the other hand, in the configuration shown in FIGS. 10 and 11 in which the ventilation part is formed from a single sheet metal, it is necessary to manufacture various ventilation parts with different numbers and positions of ventilation holes, and some parts may be damaged. Even the whole thing had to be replaced.

The present invention has been made in view of these conventional drawbacks, and allows ventilation holes to be easily formed in the housing without changing the appearance of the housing, according to the number and position of ventilation holes desired by the user. It is an object of the present invention to provide a housing structure for an electronic device that allows for a ventilation part and in which an inclined plate constituting a ventilation section does not protrude into the housing.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides an armor plate portion in which a plurality of ventilation holes are formed in parallel and an inclined plate is provided along the ventilation holes on the back side, and this armor. a first armor plate set including a first back plate part attached to the back side of the plate part and blocking the ventilation hole; At least one of the second armor plate set includes the ventilation hole of the housing and a second back plate part having a ventilation hole formed opposite to the ventilation hole of the housing. A plurality of sets are provided with the surfaces thereof exposed to the outside of the housing.

(Function) In the present invention, in the opening portion formed in the casing,
By simply attaching the second armor plate assembly to the areas that require ventilation holes and the first armor plate assembly to the areas that require sealing, the ventilation holes can be placed at the location of the user's desired housing. can be formed. Moreover, since only the front surfaces of the armor plates of the first and second armor plate sets are exposed to the outside of the housing, the exterior of the housing can be made the same regardless of the number and position of the ventilation holes. can. Moreover, since the tip side of the inclined plate of the armor plate is covered with the first back plate or the second back plate, the operator may feel uncomfortable when opening the door of the housing. There is no risk of injury from the inclined board during work.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to FIGS. 1 to 5.

FIG. 2 is an external view showing the casing of the electronic device, where 20 is the main body of the casing, and 21 is a door of the casing. As shown in FIGS. 1 and 3, the door 21 includes a frame portion 24 and a first armor plate set 2 attached to cover an opening 25 of the frame portion 24.
6 and a second armor plate set 27, and these armor plate sets 26, 27 are fixed to the frame portion 24 by fixing means such as screws 28.

The first armor plate assembly 26 is composed of an armor plate section 30 and a first back plate section 31, as shown in FIG.

It has become. The dimensions of the armor plate portion 30, the number of ventilation holes 32, etc. are determined in consideration of ease of assembly work, etc. The first back plate portion 31 has a box-shaped portion 3 with one side open.
4, and this first back plate part 31 is connected to the armor plate part 3.
0 (the surface from which the inclined plate 33 protrudes), the ventilation hole 32 of the armor plate portion 30 and the inclined plate 33 are covered by the box-shaped portion 34.

The second armor plate assembly 27, as shown in FIG. 5, is composed of an armor plate portion 30 and a second back plate portion 36.

The second back plate portion 36 has a cross section bent into a substantially U-shape, and the flat plate portion 37 is provided with ventilation holes 38 in parallel. When the back plate part 36 is attached to the back surface of the armor plate part 30, the ventilation holes 38 are positioned opposite to the ventilation holes 32 of the armor plate part 30.

As shown in FIG. 1, the first armor plate set 26 is attached to the frame 24 with the front side of the armor plate 30 exposed through the opening 25, and the back side of the armor plate 30 is The first back plate portion 34 is attached.

Similarly, in the second armor plate set 27, the armor plate portion 30 is
