Description

The present invention relates to a blank panel that covers a front opening of a portion where equipment is not mounted in a rack for storing electrical equipment.

As a rack for storing electrical equipment, it is common to install mount angles on both sides of the front of the housing and use equipment mounting holes formed at a constant pitch in the mount angle to mount equipment such as servers. be. Many such racks have a cooling structure that sucks cold air from the front of the housing to cool the equipment and exhausts the heated air from the back.

The size of the equipment is standardized, and the distance between the equipment mounting holes on the left and right mount angles is determined according to the width dimension. In addition, the pitch of the equipment mounting holes of the mount angle is determined according to the height dimension. The standardized height is called the unit height.

In such a rack, if the portion where the equipment is not mounted is opened as it is, the cold air penetrates the back surface as it is because the opening has a small flow resistance, and the cooling function of the equipment is deteriorated. .. Therefore, conventionally, a sealing plate called a blank panel is attached to close the opening. For example, Patent Document 1 describes a blank panel that can be easily mounted by forming hollow protrusions on both the left and right sides of the panel body and inserting these protrusions into the device mounting holes formed in the mount angle. There is.

Dimensional tolerances are set for the equipment mounting holes in the rack, and the distance between the left and right equipment mounting holes may change within that range. For this reason, if the distance between the left and right equipment mounting holes formed in the mount angle of the rack is narrow, the distance between the left and right protrusions of the blank panel does not match, and the blank panel must be bent and mounted. there were. If such mounting is performed, a gap may be created between the blank panel and the devices mounted above and below the blank panel, and cold air may leak.

Therefore, an object of the present invention solves the above-mentioned conventional problems, and even if the distance between the left and right equipment mounting holes formed in the mount angle fluctuates within the range of the dimensional tolerance, the gap is surely not generated. It is to provide a mountable blank panel.

The first invention made to solve the above-mentioned problems is a blank panel which is attached between mount angles erected on both sides of the front surface of the housing to cover the front opening of the housing, and is a panel body. At one end, a large-diameter hole that is extended in the left-right direction longer than the height direction is provided, and the first protrusion having a presser portion that is separably formed at the end of the panel body is cut off, and this large-diameter hole is cut off. It is characterized in that it is inserted into a device mounting hole of a mount angle and fixed through a portion.

A second invention made to solve the above problems is a blank panel attached between mount angles erected on both sides of the front surface of the housing to cover the front opening of the housing, and is a panel main body. A first protrusion having a large-diameter hole that is extended in the left-right direction longer than the height direction at one end of the panel body, and a holding portion formed at the end of the panel body via a bendable flexible portion. It is characterized in that the portion is bent and inserted into the equipment mounting hole of the mount angle through the large-diameter hole portion to be fixed.
In either case, it is preferable that the panel body and the holding portion are formed so as to be separable in the vertical direction in units of the unit height of the device mounted on the mount angle. Further, it is preferable to form a second protrusion to be inserted into the device mounting hole of the mount angle at the end of the panel body opposite to the large diameter hole.

The blank panel of the present invention is provided with a large-diameter hole portion that is extended in the left-right direction longer than the height direction at one end of the panel body, and the first protrusion portion having the holding portion is mounted at a mounting angle through the large-diameter hole portion. Since it is inserted into the device mounting hole and fixed, the first protrusion having the holding portion can be reliably inserted even if the position of the device mounting hole of the mount angle is slightly changed. Therefore, it can be attached without causing a gap.

Hereinafter, preferred embodiments of the present invention are shown.
FIG. 1 is a front perspective view showing a single unit of the blank panel of the first invention, and FIG. 2 is a back perspective view thereof. In these figures, 10 is a horizontally long panel body. The horizontal width is a dimension according to the distance between the mount angles erected on both sides of the front surface of the housing, and the vertical width is a dimension according to the unit height of the device mounted on the mount angle. In the present embodiment, the panel main body 10 is a thin plate made of resin, and horizontally long ribs 11 are formed in the central portion excluding both ends of the panel main body 10 in order to provide rigidity.

Both ends of the panel body 10 are flat plate portions without ribs 11, and a large-diameter hole portion 12, a pressing portion 13, and a first protrusion portion 14 are formed at one end thereof. The large-diameter hole portion 12 has a horizontally long structure in which the length 12b in the left-right direction is extended from the length 12a in the height direction, and as shown in FIG. 8 described later, the device mounting of the mount angle 20 It is horizontally longer than the hole 21.

The first protrusion 14 is integrally formed on the holding portion 13. The first protrusion 14 is inserted into the device mounting hole 21 of the mount angle 20 and fixed, and is preferably hollow in order to have elasticity. In the first embodiment, as shown in FIG. 3, the pressing portion 13 is formed at the end portion of the panel main body 10 so as to be detachable via the separating portion 15. FIG. 4 shows a state in which the holding portion 13 is separated.

Further, a second protrusion 16 to be inserted into the device mounting hole 21 of the mount angle 20 on the opposite side is formed at the end portion of the panel main body 10 on the side opposite to the large diameter hole portion 12. Like the first protrusion 14, the second protrusion 16 is also inserted into the device mounting hole 21 of the mount angle 20 and fixed, and has a hollow shape in order to have elasticity. The second protrusion 16 is formed on the surface of the panel body 10 opposite to the first protrusion 14.

Although the blank panel is shown as a single unit in FIGS. 1 to 4 described above, practically, as shown in FIGS. 5 and 5, the blank panel is separated in the vertical direction in units of the unit height of the device mounted on the mount angle 20. It is preferable to form it as much as possible so that it can be separated and used as needed.

In order to use the blank panel of the present invention configured as described above, as shown in FIG. 7, the second protrusion 16 is first inserted into the device mounting hole 21 of the mount angle 20, and the disconnection portion 15 is cut and pressed. The portion 13 is separated from the panel main body 10. As shown in FIG. 8, since the large-diameter hole portion 12 is horizontally longer than the device mounting hole 21 of the mount angle 20, even if the position of the device mounting hole 21 varies slightly within the dimensional tolerance, it is large. It does not come off from the diameter hole portion 12. Therefore, if the first protrusion 14 having the holding portion 13 is inserted into the device mounting hole 21 through the large-diameter hole portion 12 and fixed, the panel main body 10 is separated from the detached portion 15 as shown in FIGS. 9 to 11. And by the first protrusion 14, it is surely fixed without causing a gap.

It should be noted that FIGS. 5 to 10 show a state in which 10 single blank panels are connected vertically, but it goes without saying that the number of blank panels is appropriately cut and used according to the height of the opening to be closed. Nor. If the blank panel is continuously molded vertically in this way, there is an advantage that the device can be mounted at one time even when the devices are not mounted in a plurality of stages. Further, if the detachable portion 15 is formed to be detachable at the end portion of the panel main body 10 as in this embodiment, there is no risk of loss before use and the molding cost can be reduced.

12 to 14 show a second embodiment of the present invention. In the first embodiment described above, the pressing portion 13 is formed so as to be detachable via the separating portion 15 at the end portion of the panel main body 10, but in the second embodiment, the pressing portion 13 is formed at the end portion of the panel main body. It is formed via a bendable portion 17. The pressing portion 13 includes a first protruding portion 14.

In the blank panel of the second embodiment, the holding portion 13 is bent 180 degrees from the flexible portion 17 and inserted into the device mounting hole 21 from the large diameter hole portion 12 to be fixed, and the other points are the first. It is the same as the embodiment. In the second embodiment, since the holding portion 13 is not separated from the panel main body 10, the risk of loss can be completely eliminated as compared with the first embodiment. Further, if the flexible portion 17 of the second embodiment is formed so as to be separable, the usage in which the first protrusion 14 is separated as in the first embodiment, or the folding of the second embodiment can be used. It is also possible to use both methods by bending.

As described above, in the blank panel of the present invention, the first protrusion 14 can be reliably inserted even if the position of the device mounting hole 21 of the mount angle 20 is slightly changed. Therefore, there is an advantage that it can be securely attached without causing a gap.
