Abstract

PROBLEM TO BE SOLVED: To make small-sized a can body which stores a stack of excessive- length storage cases and to prevent connection operability from being lost. SOLUTION: A horizontal shaft 73 is supported on a fixed member 71 fixed to the wall 13 of the can body, a support member 75 is fitted rotatably to the horizontal shaft 73, and excessive-length storage cases 11 are supported on the support member 75 in a stacked state. A vertical shaft 63 is fitted to the support member 75 and the respective excessive-length storage cases 11 are fitted rotatably to the vertical shaft 63. The support member 75 is enabled to stop rotating at a position α where the excessive-length storage cases 11 are supported horizontally and a position β where they are supported vertically. Each excessive-length storage case 11 is rotated on the vertical shaft 63 while supported horizontally, so that it can be drawn out of the stack position individually.

【0013】下側ケース15と上側ケース17は、第一の軸嵌部61に第二の軸嵌部65を嵌合させるようにして積層され、これによって1組の余長収納ケース11が構成される。 [0013] lower case 15 and upper case 17 is laminated on the first shaft fitting portion 61 so as to fit the second shaft fitting portion 65, thereby constituting a set of slack storage case 11 It is.

【0014】図1は以上のような2層型余長収納ケース11を2組使用した本発明の一実施形態を示す。 [0014] Figure 1 shows an embodiment of the present invention using a two-layer type excess length storage case 11 as described above two sets. この回動型光ファイバ心線余長収納装置は固定部材71を備えている。 The rotating optical fiber excess length accommodating device is provided with a fixing member 71. この固定部材71は、上面が水平になるように、後端縁折り曲げ部をネジ等によって函体の奥壁13 The fixing member 71, so that the upper surface is horizontal, the box-body rear edge bent portion by a screw or the like back wall 13
に固定されるものである。 It is intended to be fixed to. 固定部材71は前端縁側の下部に水平軸73を奥壁13と平行になるように支持している。 Fixing member 71 supports the horizontal shaft 73 so as to be parallel to the back wall 13 in the lower portion of the front end edge side. また水平軸73にはそれを中心として回動できるように支持部材75が取り付けられている。 Further and support member 75 is attached to the horizontal shaft 73 can be rotated around it.

【0015】支持部材75は前述のような2層型余長収納ケース11を2段に支持するもので、上面板75a The support member 75 is intended to support the two-layer type excess length storage case 11 as described above in two stages, upper plate 75a
と、背面板75bと、下面板75cと、必要に応じ2段の余長収納ケース11の間に介挿される中間板(図示せず)とで構成されている。 When the rear plate 75b, and is configured de and lower plate 75c, an intermediate plate inserted between the slack storage case 11 of the second stage as necessary (not shown). また支持部材75は、水平軸73付近にストッパー77を一体に有しており、このストッパー77は、余長収納ケース11が水平な状態(図1のαおよび図2の状態)になると、固定部材71の軸支持部71aの下面に突き当たるように形成されている。 The support member 75 has integrally a stopper 77 around the horizontal axis 73, the stopper 77, the slack storage case 11 is in a horizontal state (state of FIG. And α in FIG. 1 2), fixed It is formed so as abuts against the lower surface of the shaft support portion 71a of the member 71. したがって支持部材75は、余長収納ケース11が水平な状態(図1のαおよび図2の状態)で回動を停止できることになる。 Thus the support member 75 is slack storage case 11 is able to stop the rotation in a horizontal state (state of FIG. And α in FIG. 1 2). また支持部材75は、余長収納ケース11が垂直な状態(図1のβおよび図3の状態)になると、固定部材71の上に載ってしまうため、その状態で回動を停止できることになる。 The support member 75, when slack storage case 11 is perpendicular state (state of FIG. And β in FIG. 1 3), for thereby resting on the fixed member 71, becomes possible to stop the rotation in this state . つまり支持部材75は図1のαの状態とβの状態との間を往復回動できるようになっている。 That support member 75 is adapted to be reciprocatingly rotated between the states of the state and β of α in Fig.

【0016】支持部材75には垂直軸63が取り付けられている。 [0016] The support member 75 is mounted a vertical axis 63. 垂直軸63は、上端を上面板75aに固定され、下端を下面板75cに固定されている。 Vertical shaft 63 is fixed to the upper end to the upper plate 75a, and is fixed to the lower end to the lower plate 75c. この垂直軸63には前述の2層型余長収納ケース11の下側ケース15の軸嵌部61が回動可能に嵌合されている。 Shaft fit portion 61 of the lower case 15 of the two-layered excess length storage case 11 described above is fitted rotatably in the vertical axis 63. 上側ケース17の軸嵌部65は下側ケース15の軸嵌部61に回転可能に嵌合されている(上側ケース17の軸嵌部6 Shaft fit portion of the shaft fit portion 65 is rotatably fitted into the shaft fit portion 61 of the lower case 15 (upper case 17 of the upper case 17 6
5が垂直軸63に直接嵌合する構造でもよい)。 5 may have a structure that fits directly to the vertical axis 63). このため2層型余長収納ケース11は、図1のαのように水平に配置されている状態で、図2のように垂直軸63を中心として回動させることにより手前側に引き出すことが可能である。 Thus two-layered excess length accommodating case 11, while being horizontally positioned as α in Figure 1, be pulled out to the near side by pivoting about a vertical axis 63 as shown in FIG. 2 possible it is. また下側ケース15または上側ケース17 The lower case 15 or upper case 17
を個別に引き出すことも可能である。 It is also possible to draw individually.

【0017】この回動型光ファイバ心線余長収納装置は以上のような構成であるから、図1のβおよび図3のように余長収納ケース11を垂直に立てた状態で函体に収容することができる。 [0017] Since the rotation type optical fiber excess length storage device is configured as described above, in a box body in an upright state slack storage case 11 vertically as shown in Figure and β in FIG. 1 3 it can be accommodated. このため函体の奥行き寸法を小さくすることができる。 Therefore it is possible to reduce the depth dimension of a box body. また単心コネクタ29の接続切替などの作業を行う場合には、支持部材75を回動させれば図1のαおよび図2のように余長収納ケース11を水平配置にすることができ、かつ所要のケース11、15 In the case of performing tasks such as connection switching of single-fiber connector 29, the slack storage case 11 as shown in α and 2 of Figure 1 when caused to rotate the support member 75 can be horizontally disposed, and requirements of the case 11, 15
または17を手前側に引き出すことができるので、作業を容易に行うことができる。 Or it is possible to draw 17 to the front side, it can be performed easily work.

【0018】なお以上の実施形態では、余長収納ケースが2層型の場合について説明したが、本発明は1層型の余長収納ケースを複数枚積層した場合についても同様に適用可能である。 [0018] Note that in the above embodiment, although slack storage case has been described for the case of two-layer type, the present invention is also applicable to the case where the stacked plurality of slack storage case for one-layer type .

【0019】 [0019]

【発明の効果】以上説明したように本発明によれば、複数枚の余長収納ケースの積層体を垂直に立てた状態で函体に収容することができるので、函体の奥行き寸法を小さくでき、函体を小型化できる利点がある。 According to the present invention as described in the foregoing, it is possible to accommodate to a box body in a state of upright stack of a plurality of slack storage case vertically, small depth dimension of a box body can, it can be advantageously downsized a box body. また接続切替などの作業を行うときは、余長収納ケースの積層体を水平にして、所要の余長収納ケースを個別に引き出すことができるので、作業性も良好である。 Also when performing tasks such as connection switching is slack storage case the laminate in the horizontal, it is possible to draw the required slack storage case individually, it is also good workability.
