FIG. 4 is a schematic diagram illustrating a state where it is difficult for humans to enter a cable fixing portion provided on a conventional cable fixing arm. In FIGS. 3 and 4, 1 is an optical cable, 2 is a cable fixing arm, 3 is a straw clamp, 4
Is a hand. Conventionally, as shown in FIG. 3, an optical cable fixing method used for an optical wiring rack into which a plurality of and several types of optical cables are drawn is a method in which an optical cable 1 is loosely fastened to a cable fixing arm 2 arranged in the rack. And the side pressure is fixed using screws or the like.

However, (1) When a large number of optical cables are fixed at a high density, the optical cables may not be easily removed. As shown in FIG. 4, when a large number of optical cables 1 are fixed at a high density, human hands 4 may not be able to reach the optical cable 1 fixed at the back. (2) Considering the expansion / removal of the optical cable fixing part, there is a limit to high-density fixing. That is, in order to add / remove the optical cable fixing portion, it is indispensable to individually fix the optical cables, and to perform the individual fixing, it is necessary to secure a space for a hand between the optical cables.

[0004]

As a result of various studies on the above problems, the present inventor has made it easy to add / remove individual optical cable fixing portions by providing a slide function between optical cable fixing arms constituting an optical wiring rack. The present inventors have found that high-density deployment of optical cable wiring is possible, and have completed the present invention. That is, the present invention provides: an optical cable fixing part structure which provides a sliding function between a plurality of optical cable fixing arms constituting an optical distribution rack and enables extension / removal of an individual optical cable fixing part arranged on the fixed arm. provide. Another feature is that a detachable cable fixing unit is provided on the optical cable fixing arm. Another feature is that the cable fixing unit provides compatibility depending on the cable diameter. Another feature is that a plurality of slits are provided in the small-diameter cable fixing unit. Another feature is that the small-diameter cable fixing unit is a plate made of a material that does not damage the optical cable. Hereinafter, the present invention will be described in detail with reference to the drawings.

[0005]

[Function] (1) The cable fixing arm is provided with a sliding function, and the cable fixing portion attached to the fixing arm is slid, so that a space (gap) for a hand to be extended / removed can be secured (claim) Item 1). (2) Since the cable fixing unit is provided on the cable fixing arm, it is possible to perform a very troublesome cable fixing operation outside the frame (claim 2). (3) The cable fixing unit can arbitrarily exchange the diameter ratio of the optical cable to be introduced by giving compatibility even if the cable diameter is different (claim 3). (4) Since a plurality of slits are provided in the small-diameter cable fixing unit, the cables can be individually gripped without putting a hand on the circumference of the optical cable, thereby enabling high-density fixing of the individual optical cable. Item 4).

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the following examples, which do not limit the scope of the present invention.
FIG. 1 is a schematic diagram illustrating an optical cable fixing portion structure of the present invention. FIG. 2 is a schematic diagram illustrating a state in which a slit is provided in a small-diameter cable fixing unit constituting the optical cable fixing unit structure of the present invention. 1 and 2, 1 is an optical cable, 2 is a cable fixing arm, 5 is an individual cable fixing part, 6 is a fixing unit, 7 is a slit, 8 is a space, 9 is a slice plate, 10 is a rail, and 11 is a large diameter cable. The fixing unit 12 is a small-diameter cable fixing unit.

(I) Slide mechanism: As shown in FIG. 1, a rail 10 is installed at a place where the cable fixing arm 2 attached to the optical distribution rack is attached, and a slide plate 9 is placed on the rail 10 and The cable fixing unit 2 is provided with a small-diameter cable fixing unit and large-diameter cable fixing units 11 and 12, and the cable fixing arm 2 is provided with a slide mechanism such as a rail. By installing the slide mechanism, a space (gap) 8 for a hand can be secured, and extension / removal can be easily performed. Thus, when fixed,
The fixed arms 2 can be densely packed and housed at high density.

(Ii) Hooking mechanism As shown in FIG. 1, a hooking mechanism (not shown) such as a removable hook may be provided on the slide plate 9 to provide the cable fixing unit 6. Extremely troublesome cable fixing work can be performed off-board. (iii) Compatibility As shown in FIG. 1, the cable fixing unit includes a large-diameter cable fixing unit 11 and a small-diameter cable fixing unit 12.
Even if the cable diameter differs between the units to be fixed, compatibility can be individually provided, and the ratio of the diameter of the optical cable to be introduced can be arbitrarily changed.

(Iv) Slit for suspending a small-diameter optical cable In order to wire an optical cable around a fixed unit, a suspension mechanism such as a mounting plate provided around a cable fixing arm or directly tightening with a straw is used. However, in the case of the small-diameter cable fixing unit 12, as shown in FIG. 2, a slit 7 may be provided in the fixing unit, the optical cable 1 may be inserted into the slit, and the optical cable may be fixed by lateral pressure or hooking. Thereby, the optical cable can be fixed at a high density because it is only necessary to access the optical cable from a certain direction, not on the circumference of the optical cable. As the small diameter cable fixing unit, it is preferable to use a plate plate made of a material that does not damage the optical cable.

[0010]

As described above, according to the present invention, (i) by providing a slide function between the optical cable fixing arms, it is possible to easily add / remove the individual optical cable fixing portion and to achieve high-density deployment of the optical cable wiring. Become. (ii) Since the cable fixing arm is provided with the cable fixing unit which can be easily removed, it is possible to perform a very troublesome cable fixing operation outside the frame. (iii) The cable fixing unit can exchange the diameter ratio of the optical cable arbitrarily so as to have compatibility even if the cable diameter is different. (iv) Since a plurality of slits are provided in the small-diameter cable fixing unit, the cables can be individually gripped without putting a hand on the circumference of the optical cable, and the optical cable can be fixed with high density.
