Abstract

<P>PROBLEM TO BE SOLVED: To provide an optical distribution board which can attach rack-mounted equipment. <P>SOLUTION: The optical distributing board 1 has erected a support 9 for drilling a number of screw holes 9a in the height direction to the right and left of a front side of the inside of a box body 7. A size between the supports 9 is provided for attaching the equipment of 19 inch width used for the communications equipment or the like, and a pitch between the screw holes 9a is formed into the same size as the pitch of the screw holes of a mount angle of a general-purpose rack. The mount equipment 11 is fitted from the front between the supports 9, and a mount part 12 projected from right and left sides is made to abut against the support 9 to be screwed and fixed with an attachment screw 13. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a device mounting structure for an optical distribution board for connecting optical fibers.
[0002]
[Prior art]
Conventionally, an optical wiring board has a rear surface of a device abutted against a back plate of a box body having a door body openably and closably provided at a front opening, and a bolt is inserted through a bolt insertion hole to be screwed and fixed (Patent Literature) 1). There is also a rack-mount type device that can be mounted on a rack for storing communication devices and the like (see Patent Document 2).

[0004]
[Problems to be solved by the invention]
For this reason, there is a case where it is desired to attach a rack mount type device to the optical distribution board for the purpose of sharing the device, but there is a disadvantage that the conventional optical distribution board cannot attach the rack mount type device.
[0005]
SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide an optical distribution board to which a rack-mounted device can be attached.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, an optical distribution board for connecting an optical fiber is characterized in that a support column on which a rack-mount type device can be mounted is erected inside.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
In the optical distribution board, a column having a number of screw holes formed in the height direction is erected inside the box body. The dimension between the supports is set to a dimension in which a 19-inch wide device used in communication equipment or the like is attached, and the pitch between the screw holes is formed to be the same as the pitch of the screw holes in the mounting angle of the general-purpose rack. The rack mount type device is fitted between the columns from the front, and the mounting portions projecting from the left and right side surfaces are brought into contact with the columns and screwed and fixed with mounting screws.
[0008]
【Example】
An embodiment of an optical distribution board according to the present invention will be described with reference to the accompanying drawings of FIGS.
[0009]
The optical wiring board 1 forms a box body 7 with a top plate 2, a bottom plate 3, left and right side plates 4 and 5, and a back plate 6, and a front opening is closed by a door body 8 so as to be openable and closable. On the front side inside the box body 7, columns 9 extending from the bottom plate 3 to the top plate 2 are provided upright at intervals on the left and right.
[0010]
The dimension between the posts 9 is set to a size to which a 19-inch wide device used for communication equipment or the like is attached, and a number of screw holes 9 a are formed in the height direction of the posts 9. The pitch between the screw holes 9a is formed to the same size as the pitch of the screw holes of the mounting angle for mounting equipment provided on a general-purpose rack (not shown). A frame-shaped wiring holder 10 for holding wiring is screwed and attached to the side surface of the support 9.
[0011]
The rack-mount type device 11 is formed such that mount portions 12 project from right and left sides so as to be attached to a general-purpose rack, and a screw insertion hole (not shown) is formed in the mount portion 12.
[0012]
The rack-mount type device 11 is fitted between the columns 9 from the front surface of the box body 7 so that the mounting portion 12 abuts against the columns 9. 13 is screwed into the screw hole 9a of the column 9 and fixed.
[0013]
It should be noted that equipment not formed in a rack-mount type can be fixed by screwing to the back plate 6 of the optical distribution board 1. It is recessed inward so as not to protrude. In addition, as shown in FIG. 5, a device 15 which is not formed in a rack-mount type is a rack-mount type mounting device in which mount portions 16b are formed to protrude from right and left side surfaces of a support 16a formed in a substantially U-shape. It can also be attached via the member 16.
[0014]
【The invention's effect】
As described above, in the optical distribution board for connecting the optical fibers, the columns on which the rack-mounted devices can be mounted are erected inside, so that the rack-mounted devices can be mounted and the devices can be shared. This has the effect that inventory can be reduced and costs can be reduced.
