Description

This is a U-turn portion enclosing frame member 7 having a frame portion that surrounds the U-turn portion G of the cord K that rises toward the suspension means 6 in the lower position after hanging down along the side plate 12B. (See FIG. 5).

次に、光配線盤の使用方法（作用）について説明する。
図３に示すように、アダプタ90には、鉛直背板11の裏面11ｂ側で接続相手側光ファイバの一端が、予め接続されている。
配線収納部10の開口前方側に突出したアダプタ90に、そのアダプタ90と対応するコネクタ99を有する接続側光ファイバコードＫの一端Ｋａが接続される。 Next, the usage method (action) of the optical wiring board will be described.
As shown in FIG. 3, one end of the connection partner side optical fiber is connected in advance to the adapter 90 on the back surface 11 b side of the vertical back plate 11.
One end Ka of a connection-side optical fiber cord K having a connector 99 corresponding to the adapter 90 is connected to the adapter 90 protruding forward of the opening of the wiring storage unit 10.

図２と図３及び図５に示すように、アダプタ90に一端Ｋａが接続されたコードＫは、棚板部材２の棚面壁20に立設されたコードガイド28にて、左右方向水平状に方向変換され、ループ状の余長部を形成せずに、挟持部材３によって左右方向水平状に保持され、下方誘導湾曲部21に沿って、余長部包囲枠部材５の枠内（包囲空間59）へ導入される。コードＫは、余長部包囲枠部材５を上方から下方へ挿通後に、上昇して余長部包囲枠部材５を下方から上方へ再び挿通し、図11に示すように開放状態の懸架手段６の支持部材61に懸架される。一方の面状ファスナ部91と他方の面状ファスナ部92を取着させると、図２と図３及び図５に示すように、コードＫは、下方誘導湾曲部21と懸架手段６の間でＵ字状（谷状）の余長配線部Ｅを形成し、余長配線部Ｅと他方の側板12Ｂの間で山型湾曲配線部Ｆを形成する。 As shown in FIGS. 2, 3, and 5, the cord K having one end Ka connected to the adapter 90 is horizontally formed by a cord guide 28 erected on the shelf surface wall 20 of the shelf board member 2. The direction is changed and the loop-shaped surplus length portion is not formed, but is held in the horizontal direction by the clamping member 3, and along the lower guiding curved portion 21, the inside of the surplus length portion enclosing frame member 5 (enclosed space) 59). The cord K is inserted through the surplus length portion enclosing frame member 5 from above to below, and then rises and reinserts the surplus length portion envelopment frame member 5 from below to above, so that the suspension means 6 in the open state as shown in FIG. It is suspended on the support member 61. When one planar fastener portion 91 and the other planar fastener portion 92 are attached, the cord K is placed between the lower guiding curved portion 21 and the suspension means 6 as shown in FIGS. A U-shaped (valley-shaped) surplus wiring part E is formed, and a mountain-shaped curved wiring part F is formed between the surplus wiring part E and the other side plate 12B.

さらに、余長部包囲枠部材５にて、余長配線部Ｅは、振れや移動が規制されると共に鉛直背板11に接近した平行面上に保持される。懸架手段６にて、山型湾曲配線部Ｆは、振れや移動が規制されると共に鉛直背板11に接近した平行面上に保持される。
つまり、アダプタ群９寄りに谷状の余長配線部Ｅを有すると共に側板12Ｂ寄りで山型湾曲配線部Ｆを有する波状配線部Ｗが鉛直背板11に接近した平行面上に形成される。 Further, the surplus length portion surrounding frame member 5 holds the surplus length wiring portion E on a parallel plane that is controlled to swing and move and that is close to the vertical back plate 11. In the suspension means 6, the mountain-shaped curved wiring portion F is held on a parallel plane that is controlled to swing and move and is close to the vertical back plate 11.
That is, the corrugated wiring portion W having the valley-shaped extra-long wiring portion E near the adapter group 9 and the mountain-shaped curved wiring portion F near the side plate 12B is formed on a parallel plane close to the vertical back plate 11.

さらに、コードＫの他端Ｋｂが、一端Ｋａが接続されている（上位置の）アダプタ群９より下位置のアダプタ群９のアダプタ90に接続する場合に、図２と図４及び図５に示すように上位置の懸架手段６から他方の側板12Ｂに沿って垂れ下がった後に下位置の懸架手段６に向かうようにＵターンして上昇するＵターン部Ｇは、Ｕターン部包囲枠部材７の枠内（包囲空間79）によって、前後左右方向の振れ及び移動が規制されると共に、鉛直背板11の直交平面（他方の側板12Ｂに平行な面）上に保持される。言い換えると、Ｕターン部Ｇが他方の側板12Ｂに平行な面上に保持された後、コードＫは左右内方に向かって下位置の懸架手段６に懸架される。 Further, when the other end Kb of the cord K is connected to the adapter 90 of the adapter group 9 in the lower position than the adapter group 9 to which the one end Ka is connected (upper position), FIG. 2, FIG. 4 and FIG. As shown in the figure, the U-turn part G that rises by making a U-turn so as to go down to the suspension means 6 in the lower position after hanging from the suspension means 6 in the upper position along the other side plate 12B By the inside of the frame (enclosed space 79), the swing and movement in the front / rear and left / right directions are restricted, and the vertical back plate 11 is held on an orthogonal plane (a plane parallel to the other side plate 12B). In other words, after the U-turn portion G is held on a surface parallel to the other side plate 12B, the cord K is suspended by the suspension means 6 at the lower position toward the left and right inward.

図２及び図５に示すように、コードＫの他端Ｋｂ側が、下位置の下方誘導湾曲部21と下位置の懸架手段６の間で一端Ｋａ側と同様に、余長配線部Ｅを形成し、余長配線部Ｅと他方の側板12Ｂの間で山型湾曲配線部Ｆを形成する。
つまり、配線収納部10内において、上位置のアダプタ群９に対応するコードＫの一端Ｋａ側に上位置の波状配線部Ｗと、下位置のアダプタ群９に対応するコードＫの他端Ｋｂ側に下位置の波状配線部Ｗと、を有し鉛直背板11に接近した平行面上の上下２重波状配線部を形成し、かつ、鉛直背板11の直交平面上にＵターン部Ｇを形成した配線となる。このように平面視直交する鉛直背板11と他方の側板12Ｂに沿って、平面視直交状に、光ファイバコードＫが配線されている部位を有している。このような配線は、コードＫが許容曲げ半径（例えば半径３０ｍｍ）以上の半径をもって配線されていることが一目で直感的にわかり、許容曲げ半径の確認作業を容易にする。また、切換作業等の際に、コードＫを目視で追いかけることを容易にする。しかも、図１と図２に示す正面視に於ける左右幅寸法が（従来よりも）著しく減少して、コンパクト化を図り得る利点がある。 As shown in FIGS. 2 and 5, the other end Kb side of the cord K forms a surplus wiring portion E between the lower guide bending portion 21 at the lower position and the suspension means 6 at the lower position in the same manner as the one end Ka side. Then, a chevron-shaped curved wiring portion F is formed between the extra length wiring portion E and the other side plate 12B.
That is, in the wiring storage part 10, the wavy wiring part W at the upper position on the one end Ka side of the cord K corresponding to the adapter group 9 at the upper position and the other end Kb side of the cord K corresponding to the adapter group 9 at the lower position. The upper and lower wavy wiring portions W are formed on the parallel plane close to the vertical back plate 11, and the U-turn portion G is formed on the orthogonal plane of the vertical back plate 11. It becomes the formed wiring. Thus, it has the part by which the optical fiber cord K is wired in the planar view orthogonal shape along the vertical back board 11 and the other side plate 12B which are orthogonal to the planar view. Such wiring makes it easy to know at a glance that the cord K is wired with a radius equal to or greater than the allowable bending radius (for example, a radius of 30 mm), and facilitates the confirmation work of the allowable bending radius. Further, it is easy to follow the code K visually when performing a switching operation or the like. In addition, there is an advantage that the left-right width dimension in the front view shown in FIGS.

なお、コードＫの他端Ｋｂ側が、接続相手側光ファイバとは別の装置や機器と接続されている場合は、懸架手段６に懸架され、他方の側板12Ｂ寄りに垂れ下がる接続ケーブルＫは、他方の側板12Ｂに沿うように、Ｕターン部包囲枠部材７を挿通し、その後、配線収納部10（筐体１）の外部に引き出される。 When the other end Kb side of the cord K is connected to a device or device other than the connection partner side optical fiber, the connection cable K suspended by the suspension means 6 and hanging toward the other side plate 12B is The U-turn portion enclosing frame member 7 is inserted along the side plate 12B, and then pulled out to the outside of the wiring storage portion 10 (housing 1).

下方誘導湾曲部21は、コードＫが水平状から急な角度で折れて垂れ下がるのを防止し、コード許容曲げ半径以上の半径をもたせて、余長部包囲枠部材５内へ導く。
また、余長部包囲部材５にスリット50ａを、Ｕターン部包囲枠部材７にスリット70ａを夫々、傾斜状に設けているので、振動等による振れだけでは、枠内からコードＫが飛び出す虞がない。作業者が意図的にコードＫを斜めに保持してスリット50ａ，70ａを挿通させれば、（枠内を上下方向に挿通させることなく）容易にコードＫを差し込んだり引き出すことが可能であり、作業効率を向上させる。 The lower guiding curved portion 21 prevents the cord K from being bent and drooped at a steep angle from the horizontal shape, and has a radius equal to or larger than the cord allowable bending radius to be guided into the extra length surrounding frame member 5.
Further, since the slit 50a is provided in the surplus length portion enclosing member 5 and the slit 70a is provided in the U-turn portion enclosing frame member 7 in an inclined shape, there is a possibility that the cord K may jump out of the frame only by vibration due to vibration or the like. Absent. If the operator intentionally holds the cord K obliquely and inserts it through the slits 50a and 70a, the cord K can be easily inserted and withdrawn (without being inserted vertically in the frame) Improve work efficiency.

また、余長配線部Ｅのアダプタ群９近傍側は挟持部材３にて滑り（移動）が防止され、他方の側板12Ｂ側は懸架手段６によって滑りが防止されている。このように、挟持部材３と余長部包囲枠部材５と懸架手段６にて、余長配線部Ｅを保持することで、コードＫに伝送効率が低下するような大きな押圧力を与えなくとも確実に余長配線部Ｅの姿勢を適切に保持する。 Further, slipping (moving) of the surplus wiring portion E in the vicinity of the adapter group 9 is prevented by the holding member 3, and slipping is prevented by the suspension means 6 on the other side plate 12 B side. In this way, the holding member 3, the extra length portion enclosing frame member 5, and the suspension means 6 hold the extra length wiring portion E so that the cord K does not have to be given a large pressing force that reduces the transmission efficiency. The posture of the extra-length wiring part E is surely held appropriately.

さらに、懸架手段６は、山型湾曲配線部Ｆの姿勢を保持する。また、懸架手段６の滑り止め帯材65は、押圧部材64がコードＫを押圧している時はもちろんのこと、押圧していない仮置き状態であっても、自重等による滑り落ちや、配線作業中の引きずりによる損傷を防止する。また、弾性被覆部材67は、コードＫの配線作業の際や、配線後の振れによって、下端縁部81ｅに接触するのを防止し、損傷を防止する。仕切り部材68は、複数本のコードＫが懸架手段６（懸架保持面61ｄ）に懸架されても、長手方向Ｌ１（配線収納部10の前後方向Ｑ）に区分けでき、長手方向Ｌ１位置の偏りを防止して、コードＫが上下方向に重なって互いに押圧し（潰し合い）伝送損失が増加するのを防止する。また、コードＫの切り換え作業の際に、対象となるコードＫを容易に発見可能としている。また、懸架されたコードＫの捩れを防止し、山型湾曲配線部Ｆを鉛直背板11に平行面上に保持する。金属帯材63は、支持部材61の長手方向Ｌ１に略均一にクッション部材62を圧縮させ適切かつ均一な弾性的押圧力をコードＫに付与する。 Furthermore, the suspension means 6 maintains the posture of the mountain-shaped curved wiring portion F. Further, the anti-slip belt member 65 of the suspension means 6 is not limited to the case where the pressing member 64 presses the cord K, and even if it is in the temporary placement state where the pressing member 64 is not pressed, Prevent damage from dragging during work. Further, the elastic covering member 67 prevents contact with the lower end edge portion 81e at the time of wiring work of the cord K or due to vibration after wiring, thereby preventing damage. The partition member 68 can be divided into the longitudinal direction L1 (front-rear direction Q of the wiring storage portion 10) even when a plurality of cords K are suspended on the suspension means 6 (suspension holding surface 61d). Therefore, it is possible to prevent the transmission loss from increasing because the cords K are overlapped in the vertical direction and pressed (collapsed). In addition, when the code K is switched, the target code K can be easily found. Further, twisting of the suspended cord K is prevented, and the mountain-shaped curved wiring portion F is held on a plane parallel to the vertical back plate 11. The metal strip 63 compresses the cushion member 62 substantially uniformly in the longitudinal direction L1 of the support member 61 and applies an appropriate and uniform elastic pressing force to the cord K.

また、懸架手段６は、図14に示すように、クッション部材62が（弾性的に）上下方向に圧縮されていない自然状態で、一端62ａ側厚み寸法Ｈａと他端62ｂ側厚み寸法Ｈｂとを略同等に設定している。そして、図15に示すように、一端62ａ側厚み寸法Ｈａが適切な弾性的押圧力を発揮する下限厚み寸法（この厚み寸法より小さくなると、コードＫを介在させて押圧した際に伝送効率に悪影響を及ぼす虞れのある寸法）以上、かつ、コードＫに適切な押圧力を発揮する上限厚み寸法（この寸法を越えるとコードＫを介在させて押圧した際に姿勢維持や滑り防止が困難となる厚み寸法）以下、である場合に、他端62ｂ側厚み寸法Ｈｂが一端62ａ側厚み寸法Ｈａと略同等となるように取着板片66の上端66ａの位置寸法（滑り止め部材65の頂部からの高さ寸法）を、所定寸法Ｙに、設定している。
言い換えると、一端62ａ側厚み寸法Ｈａが適切な押圧力を発揮する上記下限乃至上限厚み寸法の場合に、他端62ｂ側厚み寸法Ｈｂが一端62ａ側厚み寸法Ｈａと略同等となった状態で、帯体69の折れ曲がり部69ｅが取着板片66の上端66ａに当接して折れ曲がるように、取着板片66の上端66ａの位置寸法を所定寸法Ｙに設定している。 Further, as shown in FIG. 14, the suspension means 6 has a thickness dimension Ha on one end 62a side and a thickness dimension Hb on the other end 62b side in a natural state where the cushion member 62 is not (elastically) compressed in the vertical direction. They are set approximately the same. As shown in FIG. 15, the lower limit thickness dimension at which the one end 62a side thickness dimension Ha exhibits an appropriate elastic pressing force (if the thickness dimension is smaller than this, the transmission efficiency is adversely affected when the cord K is pressed. The upper limit thickness dimension that exerts an appropriate pressing force on the cord K (exceeding this dimension makes it difficult to maintain the posture and prevent slippage when the cord K is pressed through). Thickness dimension) or less, the position dimension of the upper end 66a of the mounting plate piece 66 (from the top of the non-slip member 65) so that the other end 62b side thickness dimension Hb is substantially equal to the one end 62a side thickness dimension Ha. ) Is set to a predetermined dimension Y.
In other words, in the case where the one end 62a side thickness dimension Ha is the above lower limit or upper limit thickness dimension that exerts an appropriate pressing force, the other end 62b side thickness dimension Hb is substantially equal to the one end 62a side thickness dimension Ha. The position dimension of the upper end 66a of the attachment plate piece 66 is set to a predetermined dimension Y so that the bent portion 69e of the band 69 abuts on the upper end 66a of the attachment plate piece 66 and bends.

クッション部材62の一端62ａ側厚み寸法Ｈａは、収納空間10の前方側から容易に目視できるため、一端62ａ側厚み寸法Ｈａは上記下限乃至上限厚み寸法に設定される。しかし、図16に示す比較例のように、所定寸法Ｙ未満の寸法Ｚ１に、取着板片66の上端66ａの位置寸法が設定されていたとすると、一端62ａ側厚み寸法Ｈａが上記下限乃至上限厚み寸法に設定されても、他端62ｂ側の厚み寸法Ｈｂは一端62ａ側厚み寸法Ｈａより小さくなって、他端62ｂ側に保持されるコードＫの伝送効率に悪影響を与える虞れがある。
また、図17に示す別の比較例のように、所定寸法Ｙを越える寸法Ｚ２に、取着板片66の上端66ａの位置寸法が設定されると、一端62ａ側厚み寸法Ｈａより他端62ｂ側の厚み寸法Ｈｂが大きくなって、押圧力が弱く、他端62ｂ側に保持されるコードＫの姿勢を保持できず、滑り等が発生する虞れがある。
このように、取着板片66の上端66ａの位置寸法を所定寸法Ｙに設定することで、配線収納部10の奥側となる、クッション部材62の他端62ｂ側厚み寸法Ｈｂを目視して確認する手間が省略されると共に確実に適切な押し圧力でコードＫを保持する。 Since the one end 62a side thickness dimension Ha of the cushion member 62 can be easily seen from the front side of the storage space 10, the one end 62a side thickness dimension Ha is set to the above lower limit or upper limit thickness dimension. However, as in the comparative example shown in FIG. 16, if the position dimension of the upper end 66a of the mounting plate piece 66 is set to the dimension Z1 less than the predetermined dimension Y, the one end 62a side thickness dimension Ha is the above lower limit or upper limit. Even if the thickness dimension is set, the thickness dimension Hb on the other end 62b side becomes smaller than the one end 62a side thickness dimension Ha, which may adversely affect the transmission efficiency of the cord K held on the other end 62b side.
Further, as in another comparative example shown in FIG. 17, when the position dimension of the upper end 66a of the mounting plate piece 66 is set to the dimension Z2 exceeding the predetermined dimension Y, the other end 62b is more than the one end 62a side thickness dimension Ha. The thickness dimension Hb on the side becomes large, the pressing force is weak, the posture of the cord K held on the other end 62b side cannot be maintained, and there is a possibility that slipping or the like may occur.
Thus, by setting the position dimension of the upper end 66a of the attachment plate piece 66 to the predetermined dimension Y, the thickness dimension Hb on the other end 62b side of the cushion member 62, which is the back side of the wiring housing portion 10, is visually observed. The trouble of checking is omitted, and the cord K is securely held with an appropriate pressing force.

The connection side optical fiber cord K whose one end Ka is connected to 90 is attached to the clamping member 3. After being held and suspended along the lower guiding curved portion 21, it is lifted and suspended by the suspension means 6, and a U-shaped extra-length wiring portion E is formed between the lower guiding curved portion 21 and the suspension means 6 and suspended. Since the mountain-shaped curved wiring portion F is formed by the means 6, both sides of the surplus wiring portion E can be held in an appropriate posture having a radius greater than the allowable bending radius. Moreover, the connection side optical fiber cord K can hold | maintain the mountain-shaped curved attitude | position. It is possible to prevent the suspended portion of the connection side optical fiber cord K from slipping off due to vibration or its own weight, and to prevent an undesired tension from being generated in the connection side optical fiber cord K. That is, wiring maintained at appropriate transmission efficiency can be performed. Further, the connection side optical fiber cords K are not entangled with each other, and the connection side optical fiber cords K can be easily identified (discriminated) by a connection switching operation or the like. Wiring inside the wiring storage unit 10 can be neatly and beautifully done, and the wiring can be easily checked.

また、余長配線部Ｅを、鉛直背板11に接近した平行面上に保持する余長部包囲枠部材５を備え、余長部包囲枠部材５を鉛直背板11に上下複数配設したので、余長配線部Ｅを適切な曲げ半径をもって配線・収納できる。目視で直感的に適切に配線されているか確認できる。余長配線部ＥによってコードＫの揺れと、それに伴う滑りや張力の発生を防止できる。 In addition, a surplus length encircling frame member 5 for holding the surplus length wiring portion E on a parallel plane close to the vertical back plate 11 is provided, and a plurality of surplus length portion enclosing frame members 5 are arranged on the vertical back plate 11 in a vertical direction. Therefore, the extra length wiring portion E can be wired and stored with an appropriate bending radius. It can be confirmed by visual inspection whether wiring is properly performed. The extra length wiring portion E can prevent the cord K from shaking and the accompanying slipping and tension.

また、上位置の懸架手段６から左右の側板12，12の他方12Ｂに沿って垂れ下がった後に下位置の懸架手段６に向かうように上昇する接続側光ファイバコードＫのＵターン部Ｇを、鉛直背板11の直交平面上に保持するＵターン部包囲枠部材７を備え、Ｕターン部包囲枠部材７を左右の側板12，12の他方12Ｂに上下複数配設したので、上位置のアダプタ群９と下位置のアダプタ群９を接続するような煩雑になりやすい配線を、容易に配線できる。Ｕターン部Ｇの揺れによるコードＫの滑りや張力の発生を防止できる。さらに、光配線盤の左右の幅方向を減少して、コンパクト化を図り得る。 Further, the U-turn portion G of the connection-side optical fiber cord K, which hangs down from the upper suspension means 6 along the other 12B of the left and right side plates 12, 12, and rises toward the lower suspension means 6, Since the U-turn portion surrounding frame member 7 is held on the orthogonal plane of the back plate 11 and a plurality of U-turn portion surrounding frame members 7 are arranged on the other side 12B of the left and right side plates 12, 12, the adapter group at the upper position Wiring that tends to become complicated, such as connecting the adapter group 9 to the lower adapter group 9, can be easily wired. It is possible to prevent the cord K from slipping or generating tension due to the swing of the U-turn portion G. Further, the left and right width directions of the optical wiring board can be reduced to achieve compactness.
