Description

本発明は、光配線収納箱の内側で光コードを配線するための光線路器具に関する。   The present invention relates to an optical line device for wiring an optical cord inside an optical wiring storage box.

従来、光コード配線用の可動シャーシを光配線収納箱の前後方向（奥行方向）へ引き出し可能に備えた光線路器具が知られている。例えば、図８に示すように、特許文献１の光線路器具５１は、光配線収納箱５２内の固定シャーシ５３上に可動シャーシ５４を前後方向へスライド可能に支持し、可動シャーシ５４上に多数のアダプタ５５を配設し、アダプタ５５に接続された光コード５６の束５７を隔壁５８に添わせて可動シャーシ５４の片側から他の配線機器５９に引き回すように構成されている。
特開２００５−５５７４８号公報 2. Description of the Related Art Conventionally, there has been known an optical line device provided with a movable chassis for optical cord wiring that can be pulled out in the front-rear direction (depth direction) of the optical wiring storage box. For example, as shown in FIG. 8, the optical line device 51 of Patent Document 1 supports a movable chassis 54 on a fixed chassis 53 in an optical wiring storage box 52 so as to be slidable in the front-rear direction. Adapter 55 is arranged, and a bundle 57 of optical cords 56 connected to the adapter 55 is arranged along the partition wall 58 and routed from one side of the movable chassis 54 to another wiring device 59.
JP-A-2005-55748

ところが、この種の引出式可動シャーシによると、光コードの配線密度が左右に不均一であった場合に、スライドに伴って可動シャーシに水平面内の傾動力が作用しやすい。例えば、図８の光線路器具５１によると、多数本の光コード５６を可動シャーシ５４の片側に密集状に配線しているため、アダプタ５５の出し入れにあたり、コード束５７の屈曲抵抗で可動シャーシ５４にこじれが発生し、可動シャーシ５４のスライド操作が重くなるという問題点があった。また、アダプタ５５の周囲のスペースがコード束５７の引き回し側で少なくなるため、光コード５６の増減設にあたって、配線作業に困難を伴うという不都合もあった。   However, according to this type of drawer-type movable chassis, when the wiring density of the optical cord is not uniform from side to side, tilting power in the horizontal plane tends to act on the movable chassis along with the slide. For example, according to the optical line device 51 of FIG. 8, since a large number of optical cords 56 are densely wired on one side of the movable chassis 54, the movable chassis 54 is bent by the bending resistance of the cord bundle 57 when the adapter 55 is put in and out. There has been a problem that twisting occurs and the sliding operation of the movable chassis 54 becomes heavy. Further, since the space around the adapter 55 is reduced on the side where the cord bundle 57 is routed, there is a disadvantage that wiring work becomes difficult when the optical cord 56 is increased or decreased.

そこで、本発明の目的は、光コードの配線作業にあたって可動シャーシをスムーズにスライド操作できる光線路器具を提供することにある。   SUMMARY OF THE INVENTION An object of the present invention is to provide an optical line device that can smoothly slide a movable chassis during an optical cord wiring operation.

上記の課題を解決するために、本発明の光線路器具は、光配線収納箱内に固定された固定シャーシと、固定シャーシ上にスライド可能に支持された光コード配線用の可動シャーシと、可動シャーシを固定シャーシに対し光配線収納箱の前後方向へ案内する案内機構とを備え、案内機構が前後方向へ延びる三本の案内溝と、各案内溝に係合する左右方向に三つの係合部材とを備え、左右両側の係合部材と中央の係合部材とを前後方向の反対位置に設けたことを特徴とする。   In order to solve the above problems, an optical line device of the present invention includes a fixed chassis fixed in an optical wiring storage box, a movable chassis for optical code wiring supported slidably on the fixed chassis, and a movable A guide mechanism that guides the chassis in the front-rear direction of the optical wiring storage box with respect to the fixed chassis, the guide mechanism extending in the front-rear direction, and three engagements in the left-right direction that engage with each guide groove And engaging members on both left and right sides and a central engaging member at opposite positions in the front-rear direction.

また、本発明の光線路器具は、可動シャーシ上に光コードを接続する複数のアダプタを配設し、アダプタの周囲にコード収納壁を立設し、可動シャーシの四隅に配線用の切欠部を形成したことを特徴とする。   Further, the optical line apparatus of the present invention is provided with a plurality of adapters for connecting an optical cord on the movable chassis, a cord storage wall is erected around the adapter, and wiring cutout portions are provided at the four corners of the movable chassis. It is formed.

本発明の光線路器具によれば、可動シャーシが三角形の交点に位置する三つの係合部材により三本の案内溝を介して前後方向へ直進案内される。このため、光コードの配線密度が不均一であった場合でも、こじれを生じることなく、可動シャーシをスムーズにスライド操作することができる。   According to the optical line device of the present invention, the movable chassis is guided straight forward in the front-rear direction via the three guide grooves by the three engaging members located at the intersections of the triangles. For this reason, even when the wiring density of the optical cord is not uniform, the movable chassis can be smoothly slid without causing twisting.

また、光コードの余長がアダプタの周囲に立設したコード収納壁により可動シャーシ上に整然と収納され、可動シャーシの四隅から切欠部を通して前後左右へバランスよく配線される。従って、アダプタへの配線作業を容易に行うことができるとともに、可動シャーシをより軽快にスライド操作することができる。   Further, the extra length of the optical cord is neatly accommodated on the movable chassis by the cord accommodating wall standing around the adapter, and wired in a balanced manner from the four corners of the movable chassis to the front, rear, left and right through the notches. Therefore, wiring work to the adapter can be easily performed, and the movable chassis can be slid more easily.
