Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a rack for mounting various communication devices and the like, the inside of which is divided by a partition plate, and a user is different for each stage.
[0002]
[Prior art]
In the rack 21 according to the related art, as shown in FIG. 6, a dedicated duct is not provided, the partition plate 22 is shortened, and the space between the partition plate 22 and the side plate 23 is used as the passage hole 24. Or a general-purpose duct was attached, and all cables were inserted through the duct. Thereafter, a rack as disclosed in JP-A-2002-100889 was invented.
[0003]
[Problems to be solved by the invention]
However, according to the above-mentioned conventional technology, even if each user of the rack is owned by a different user, since the line portion must be shared, the user may accidentally touch other cables during the wiring work, There was a drawback that other cables hindered work. When connecting cables, it was necessary to open all the side plates on the duct side of the rack, which was troublesome. Further, in the rack disclosed in Japanese Patent Application Laid-Open No. 2002-100889, when the position of the input / output line differs depending on each rack, the input / output line method and the installation of the duct must be designed and manufactured in each rack. Therefore, even if it is desired to change the positions of the input and output lines, the rack must be replaced, which takes a great deal of time for the design and raises the production cost.
[0004]
[Means for Solving the Problems]
Therefore, an object of the present invention is to provide a rack duct that has a simple structure and facilitates wiring work while maintaining security performance, and the structure is connected to devices mounted on each stage. In order to store cables individually for each step, the number of ducts parallel to one side of the rack can be fixed to the rails, so that incoming and outgoing lines to each step can be done from either the upper or lower side of the rack It is characterized in that the ducts can be rearranged, and that the wiring work can be performed step by step.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
The duct according to the present invention has a number corresponding to the number of stages on the side surface of the rack, and accommodates cables and the like to be connected to devices mounted on each stage of the rack. The duct is juxtaposed to the side of the rack to prevent access to the rack when the side plates are removed. The fixing of the duct is performed by screwing it to an adjustment rail provided on the side surface of the rack. If access to the rack is from the bottom of the rack, attach the duct upward from the bottom. Each of the ducts enters and exits below each step of the rack. In addition, when it is desired to change the rack installed so as to enter and exit from the bottom to the entrance and exit from the upper side, remove the partition plate, the mounting angle, the mounting rail, and the like, and attach the duct downward from the top plate. Incoming and outgoing lines from each duct are located above each step. Attach the partition plate, mount angle, mount rail, etc., and finally remove the opening cover provided on the top plate.
[0006]
【Example】
An embodiment according to the present invention will be described with reference to the accompanying drawings of FIGS.
[0007]
The rack 1 has a side panel 3 erected on a bottom plate 2 and a top plate 4 attached to an upper portion of the side panel 3 to form a main body. The rack 1 is divided into a plurality of stages by a partition plate 5. A mounting angle 6 for mounting equipment for each stage is mounted inside the rack 1. The front and back surfaces are covered with a door 7 and a panel 8, and different users mount and use communication devices and the like on each stage. Cables connected to communication devices and the like are housed in a duct 9 attached to the inner side surface of the rack 1.
[0008]
In the duct 9 according to the present invention, the cables are divided and stored in each stage. The duct 9 is arranged in parallel with the side surface of the rack 1 by the number of stages, and is fixed to an adjustment rail 10 attached to the side surface of the rack 1 by screwing or the like. The duct 9 is adjusted to the length of each step, and the incoming and outgoing lines are respectively made from the ends of the duct 9.
[0009]
The partition plate 5, the bottom plate 2, and the top plate 4 of the rack 1 are provided with duct insertion holes 11 respectively. A cover 12 is attached to the duct insertion hole 11 of the top plate 4 when the rack 1 is to enter and exit from below.
[0010]
When the incoming and outgoing lines are made from below the rack 1, the duct 9 is attached upward from the bottom plate 2. Cables connected to the devices stored in the respective stages are stored in ducts 9 connected to the respective stages, and cables are input and output from the ends of the ducts 9. Since the cables are stored separately in the duct 9 for each step, there is no possibility of accidentally touching the cables of other steps, and if the side panel 3 or the door 7 of the rack 1 is locked, entry to another step is possible. Is also difficult, and security performance can be improved.
[0011]
When the incoming and outgoing lines are made from above the rack 1, the duct 9 is attached downward from the top plate 4. Cables connected to the devices stored in the respective stages are stored in ducts 9 connected to the respective stages, and cables are input and output from the ends of the ducts 9. Since the cables are divided and stored in the duct 9 for each step, there is no possibility of accidentally touching the cables of other steps, and if the side panel 3 or the door 7 of the rack is locked, entry to other steps is possible. It is difficult, and security performance can be improved.
[0012]
In order to switch the rack 1 on which the duct 9 is attached to the rack 1 so that the incoming and outgoing lines are made from below the rack 1, the door 7 and the mounting angle 6 are removed, and the partition plate 5 is removed. The duct 9 is replaced with an incoming / outgoing line position from above. In FIG. 4, the uppermost partition plate 5 and the lowermost partition plate 5 are interchanged so that the duct insertion holes 12 match the number of ducts 9 to be mounted. The cover 13 covering the duct insertion hole 11 of the top plate 4 is removed, and the duct 3 enters and exits from above.
[0013]
Although the rack according to the present invention has been described as having four stages in FIGS. 1 to 4, as shown in FIG. 5, for example, a rack 12 divided into two stages by a partition plate 13 is similarly treated, and a duct 14 is used. Can be attached from above or below the rack 12.
[0014]
【The invention's effect】
As described above, the duct structure according to the present invention has a structure in which the ducts for the number of stages are arranged in parallel on one surface of the rack in order to individually accommodate the cables connected to the devices mounted on the respective stages, for each stage. The ducts can be rearranged so that incoming and outgoing lines to each stage can be accessed from either the upper or lower side of the rack. The workability is improved because the cables in the first row do not get in the way. Even in the existing rack, the incoming / outgoing line position can be changed with the same member. Since the same rack can be used even if the positions of the incoming and outgoing wires are different, production costs can be reduced by sharing members. In addition, since all the doors, mounting angles, mounting rails, and partition plates must be removed to re-install the duct, the structure cannot be used by users at each stage of the rack, and security performance is reduced. Can be improved.
