DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for fixing an optical fiber cable, and more particularly to an apparatus for fixing an optical fiber in a place where many cables are densely raised, such as a rising part of an optical fiber cable in an optical distribution board. It relates to a fixing device.

[0002]

2. Description of the Related Art Heretofore, a rising portion of a cable has been collectively fixed to a cable rack or the like below an optical distribution board. For this reason, it was difficult to arrange when the number of cores increased.

[0003]

As shown in FIGS. 1 and 2, a plurality of brackets 10 each having a vertically penetrating hole 16 and a set screw 18 whose tip reaches the hole 16 are provided. The optical fiber cable fixing device is arranged in a stepwise manner so as to gradually increase toward. Also,
A panel-like panel 20 is provided on one side of the optical distribution board, and at least one set of step-like blocks for fixing the tension member 32 of the optical fiber is mounted on the panel 20, and an optical fiber cable fixing device is provided. Constitute.

[0004]

[Operation] (1) When the tension member 32 of the optical fiber cable 30 is passed through the hole 16 of the bracket 10 and the set screw 18 is tightened, the optical fiber cable 30 can be fixed in a suspended state. (2) When a plurality of brackets 10 are arranged in a stepwise manner so as to gradually increase from one side to the other side, even if the brackets 10 are densely arranged so that there is no gap between adjacent brackets, FIG. As shown in FIG.
When the bracket 8 is tightened, the brackets 10 on both sides are not in the way (if the brackets 10 are arranged flat as in FIG. 4, it becomes difficult to tighten the screw 18). (3) Since the optical fiber cable 30 is also attached in a stepped manner, the optical fiber cores 34 can be arranged and taken out for each stage. (4) Since the panel-like panel surface is provided on one side of the optical distribution board, the degree of freedom in selecting the fixing position of the tension member of the optical fiber cable is large.

[0005]

FIG. 2 shows one bracket 10 and a panel 20 to which it is attached. The bracket 10 is, for example, L-shaped, and the protruding portion 12 is preferably a square bar,
The base 14 is in the shape of a square thick plate. The projecting portion 12 is provided with at least one hole 16 penetrating vertically. Set screws 18 corresponding to the respective holes 16 are provided. The mechanism for stopping the tension member is not limited to the set screw method.

The panel 20 is a flat plate which is elongated vertically, and has a width a that is equal to the width of the bracket 10 (FIG. 1). A large number of screw holes 22 are provided in the panel 20 to form a perforated plate, so that the bracket 10 can be screwed to an appropriate height. What is important here is that the bracket mounting position can be freely selected depending on the design because the panel is a panel-like panel.

As shown in FIG. 1, a large number of panels 20 are mounted between upper and lower cross members 40 and 42 such that adjacent panels are in contact with each other. Each bracket 10 is attached in a step-like manner so as to be, for example, ascending to the right. This may be a continuous step or an intermittent step. That is, an assembly including at least one block (this includes an integrated block of two or more blocks) is attached to various parts of the panel. The height between the block sets is also arbitrary. The tension member 32 of the optical fiber cable 30 is inserted into the hole 16 of each bracket 10 from below and fixed with the set screw 18. Reference numeral 34 denotes an optical fiber core (or unit). Thus, if a large number of combinations of the bracket 10 and the panel 20 having the same structure are prepared and placed, as shown in FIG.
The brackets 10 can be arranged stepwise so as to be progressively higher from one side to the other, so that the cables can also be mounted in a stepwise arrangement.

In another embodiment of the present invention, the cross section of the bracket may not be a prism but may be another cross section such as a circle. Also, instead of providing an L-shape by providing a base, the panel may be directly fixed to the bottom of the protruding portion without providing the base. Furthermore, instead of blocks one by one, an aggregated block formed by gathering several steps may be used. Still further, as described above, instead of forming a continuous step, the height may be changed appropriately according to the ease of wiring work, or a set of blocks may be dispatched to the panel surface. You may.

[0009]

According to the present invention, a large number of optical fiber cables 3 are placed in a narrow place.
0 can be arranged and fixed for different heights. Also, the number of stages can be increased or decreased as necessary,
In addition, since the bracket can be attached to an arbitrary position on the panel, the wiring arrangement of the optical distribution board becomes easy.
