Abstract

<P>PROBLEM TO BE SOLVED: To restrict the one directional length to a minimum by attaching two or more optical adapters arranged on the front face of a main body case in the state of adjoining each other in one direction. <P>SOLUTION: Since the optical distribution box 1 is structured to store the two or more optical adapters 3 on the case main body 19 so that both end faces of the case main body 19 in one direction are flush with the outside surfaces of the optical adapters on both ends in the one direction among the two or more optical adapters 3, the one directional length of the case main body 19 can be restricted to the minimum by making the length to the same length of the one directional length of the two or more adapters 3. As a result, even when the conventional optical distribution box 1 could not be installed on a standardized optical module rack by a delicate difference, it becomes possible to install the optical distribution box 1 storing two or more pieces of desired optical adapters 3 on the optical module rack. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

この発明は、光配線箱に関し、特に複数の光アダプタを一方向に並列に配設して本体ケースの前面に取り付けると共に本体ケースの一方向の長さを最小限に押さえるための光配線箱に関する。   The present invention relates to an optical wiring box, and more particularly to an optical wiring box for arranging a plurality of optical adapters in parallel in one direction and attaching them to the front surface of the main body case and minimizing the length in one direction of the main body case. .

従来、加入者系と局内との光ケーブルを接続するために、光モジュールラック、光モジュール、光カプラモジュール、光スプリッタモジュール等で光接続可能とするための光ファイバ収納ケース、あるいは光アダプタ用ベースが開発されている（例えば、特許文献１及び特許文献２参照）。   Conventionally, in order to connect an optical cable between a subscriber system and a station, an optical fiber storage case or an optical adapter base for enabling optical connection with an optical module rack, an optical module, an optical coupler module, an optical splitter module, etc. It has been developed (see, for example, Patent Document 1 and Patent Document 2).

光ファイバの接続形式としては、例えば、局内の光ケーブルから単心光ファイバに分岐して、各単心光ファイバの先端が光コネクタにて成端され、この成端した光コネクタが光ファイバ収納ケースの内側の光アダプタに接続される。一方、光ファイバ収納ケースの外側の光アダプタには、加入者側の単心光ファイバに成端された光コネクタが接続される（例えば、特許文献３参照）。なお、用途に応じて、光スプリッタやカプラなどの光部品が光ファイバの間に介設されることもある。   As an optical fiber connection type, for example, an optical cable in a station is branched into a single-core optical fiber, and the tip of each single-core optical fiber is terminated by an optical connector, and this terminated optical connector is an optical fiber storage case. Connected to the inner optical adapter. On the other hand, an optical connector terminated to a single optical fiber on the subscriber side is connected to the optical adapter outside the optical fiber storage case (see, for example, Patent Document 3). Depending on the application, an optical component such as an optical splitter or a coupler may be interposed between the optical fibers.

いずれにしても、以上のように、光ファイバ収納ケースは外部の光ファイバが光コネクタ及び光アダプタによって切り替え自在となっている。   In any case, as described above, in the optical fiber storage case, the external optical fiber can be switched by the optical connector and the optical adapter.

図６及び図７（Ａ），（Ｂ），（Ｃ）を参照するに、一般的に、従来の光配線箱としての光ファイバ収納ケース１０１は扁平縦型であって、多数の光ファイバ収納ケース１０１が、例えば図８（Ａ），（Ｂ）に示されている光モジュールラック１０３の各収納部１０５に、各光ファイバ収納ケース１０１の横幅方向の側面を隣り合うように横並びに並べて収納され、各収納部１０５に備えた光配線箱取付部１０７に固定されてユニット化されるものである。すなわち、光モジュールラック１０３で光集合モジュールが構成されるものである。   Referring to FIGS. 6 and 7A, 7B, and 7C, generally, an optical fiber storage case 101 as a conventional optical wiring box is a flat vertical type, and stores a large number of optical fibers. For example, the case 101 is stored side by side in the storage portion 105 of the optical module rack 103 shown in FIGS. 8A and 8B so that the lateral sides of the optical fiber storage cases 101 are adjacent to each other. The unit is fixed to the optical wiring box mounting portion 107 provided in each storage portion 105 and unitized. In other words, the optical module rack 103 constitutes an optical assembly module.

上記の光ファイバ収納ケース１０１に装着される光アダプタ１０９は、図６及び図７（Ｃ）に示されているように当該光アダプタ１０９の中央部に、単心光ファイバ１１１の先端を成端した光コネクタ１１３を接続、抜脱可能なコネクタ差込穴１１５が設けられており、このコネクタ差込穴１１５の図６において左右の両側には光アダプタ１０９を光ファイバ収納ケース１０１に取り付けるための取付部１１７が突出されている。また、前記各取付部１１７には、光アダプタ１０９をネジ止めして固定するための固定具としての取付用ビス１１９を挿通するビス挿通孔（図示省略）が設けられている。   As shown in FIGS. 6 and 7C, the optical adapter 109 attached to the optical fiber storage case 101 is terminated at the center of the optical adapter 109 with the end of the single-core optical fiber 111 being terminated. A connector insertion hole 115 is provided for connecting and disconnecting the optical connector 113, and the optical adapter 109 is attached to the optical fiber storage case 101 on both the left and right sides of the connector insertion hole 115 in FIG. A mounting portion 117 is projected. Each mounting portion 117 is provided with a screw insertion hole (not shown) through which a mounting screw 119 as a fixture for fixing the optical adapter 109 by screwing.

光ファイバ収納ケース１０１は、そのケース本体１２１がほぼ直方体をなす扁平縦型となっており、このケース本体１２１の前面には複数の光アダプタ１０９を取り付けるためのアダプタ取付板１２３が設けられており、このアダプタ取付板１２３には複数の光アダプタ１０９が図６において上下方向に隣接した状態で挿入するための図示しないアダプタ装着穴部が設けられている。   The optical fiber storage case 101 has a flat vertical shape in which the case main body 121 forms a substantially rectangular parallelepiped, and an adapter mounting plate 123 for mounting a plurality of optical adapters 109 is provided on the front surface of the case main body 121. The adapter mounting plate 123 is provided with adapter mounting holes (not shown) through which the plurality of optical adapters 109 are inserted in the state adjacent in the vertical direction in FIG.

前記アダプタ装着穴部の両側には複数の光アダプタ１０９の両側の取付部１１７を図６において上下方向に隣接した状態で配列して突き当てるアダプタ突当て面が設けられている。さらに、前記アダプタ突当て面には上記の取付用ビス１１９を螺合するネジ孔（図示省略）が設けられている。したがって、複数の光アダプタ１０９が図６において上下方向に隣接した状態でアダプタ装着穴部に挿入されて複数の光アダプタ１０９の両側の取付部１１７がアダプタ突当て面に突き当てられると共に、各光アダプタ１０９はそれぞれ取付用ビス１１９を取付部１１７の２箇所のビス挿通孔に挿通してアダプタ突当て面にネジ止め固定される。   On both sides of the adapter mounting hole portion, adapter abutting surfaces are provided for abutting the mounting portions 117 on both sides of the plurality of optical adapters 109 in the state of being adjacent in the vertical direction in FIG. Furthermore, a screw hole (not shown) for screwing the mounting screw 119 is provided on the adapter abutting surface. Accordingly, the plurality of optical adapters 109 are inserted into the adapter mounting holes in the state of being adjacent to each other in the vertical direction in FIG. 6, and the mounting portions 117 on both sides of the plurality of optical adapters 109 are abutted against the adapter abutting surface. The adapters 109 are each fixed with screws to the adapter abutment surface by inserting the mounting screws 119 through the two screw insertion holes of the mounting portion 117.

なお、図６及び図７（Ａ），（Ｂ），（Ｃ）では複数の光アダプタ１０９が取付用ビス１１９によりアダプタ突当て面にネジ止め固定されているが、他の固定方法としては、各光アダプタ１０９自体に備えられている板バネを利用することも行われている。つまり、光アダプタ１０９にはアダプタ装着穴部に挿入される側の対向する両側面に板バネが突設されており、光アダプタ１０９がアダプタ装着穴部に挿入されたときに前記板バネでアダプタ装着穴部の内壁面を押圧する反力により固定される。   6 and 7A, 7B, and 7C, a plurality of optical adapters 109 are screwed and fixed to the adapter abutment surface with mounting screws 119. As other fixing methods, A leaf spring provided in each optical adapter 109 itself is also used. That is, the optical adapter 109 has leaf springs projecting on opposite side surfaces on the side to be inserted into the adapter mounting hole, and when the optical adapter 109 is inserted into the adapter mounting hole, It is fixed by a reaction force that presses the inner wall surface of the mounting hole.

また、アダプタ取付板１２３には、アダプタ突当て面の図７（Ｃ）において右外側に、複数の各光アダプタ１０９に対応する線番表示１２５を表示するためのスペース１２７が設けられている。さらに、アダプタ取付板１２３の図６及び図７（Ｃ）において上部には取付用ビス１２９を挿通するビス挿通孔（図示省略）が設けられている。   In addition, the adapter mounting plate 123 is provided with a space 127 for displaying the wire number display 125 corresponding to each of the plurality of optical adapters 109 on the right outer side in FIG. Further, a screw insertion hole (not shown) through which the mounting screw 129 is inserted is provided in the upper portion of the adapter mounting plate 123 in FIGS. 6 and 7C.

光ファイバ収納ケース１０１を光モジュールラック１０３に装着するときは、アダプタ取付板１２３が各収納部１０５の光配線箱取付部１０７に突き当てられると共に、取付用ビス１２９をアダプタ取付板１２３のビス挿通孔に挿通して光配線箱取付部１０７のネジ穴１３１にネジ止め固定される。   When the optical fiber storage case 101 is attached to the optical module rack 103, the adapter mounting plate 123 is abutted against the optical wiring box mounting portion 107 of each storage portion 105 and the mounting screw 129 is inserted into the adapter mounting plate 123. The hole is inserted into the hole and fixed to the screw hole 131 of the optical wiring box mounting portion 107 with a screw.

なお、上述した複数の各光アダプタ１０９には、図６に示されている光ファイバ収納ケース１０１の外側のコネクタ差込穴１１５の他に、光ファイバ収納ケース１０１の内部側にもコネクタ差込穴（図示省略）が設けられており、このコネクタ差込穴には、光ファイバ収納ケース１０１の内部に収納される単心光ファイバ１１１の先端に成端された光コネクタが接続される。

ところで、光モジュールラック１０３は、図８（Ａ），（Ｂ）に示されているように、一般的に板材で直方体形状に形成されており、その外形寸法（外寸）が規格化されている。例えば、ＥＩＡ規格では１９インチラック〔図８（Ｃ）のラック幅寸法Ｗ０が１９インチ〕において、外寸高さＨ０が８８．１ｍｍである。したがって、光モジュールラック１０３の構成部材の板厚が１．２ｍｍである場合、内寸高さＨ１は８５．７ｍｍとなる。   By the way, as shown in FIGS. 8A and 8B, the optical module rack 103 is generally formed of a plate material in a rectangular parallelepiped shape, and its outer dimensions (outer dimensions) are standardized. Yes. For example, in the EIA standard, the outer dimension height H0 is 88.1 mm in a 19-inch rack (the rack width dimension W0 in FIG. 8C is 19 inches). Therefore, when the plate thickness of the constituent members of the optical module rack 103 is 1.2 mm, the inner dimension height H1 is 85.7 mm.

一方、前述した光アダプタ１０９も規格化されており、図７（Ｃ）を参照するに、例えば９個のＳＣアダプタを用いて従来構造の光ファイバ収納ケース１０１Ａに装着してカプラモジュール（１×８分岐）とした場合は、光ファイバ収納ケース１０１の外寸高さＨ２が８６．６ｍｍとなる。   On the other hand, the above-described optical adapter 109 is also standardized. Referring to FIG. 7C, for example, nine SC adapters are attached to the optical fiber housing case 101A having a conventional structure and a coupler module (1 × 8 branch), the outer dimension height H2 of the optical fiber storage case 101 is 86.6 mm.

したがって、光モジュールラック１０３の内寸高さＨ１は８５．７ｍｍに対して光ファイバ収納ケース１０１Ａの外寸高さＨ２が８６．６ｍｍであるので、９個のＳＣアダプタを用いたカプラモジュール（１×８分岐）は光モジュールラック１０３に実装することができないという問題点があった。   Therefore, the optical module rack 103 has an inner dimension H1 of 85.7 mm and an outer dimension H2 of the optical fiber storage case 101A is 86.6 mm. Therefore, the coupler module (1 × 8 branch) has a problem that it cannot be mounted on the optical module rack 103.

そのために、従来では、１９インチラックに対しては、ＳＣアダプタより寸法が小さいＳ’Ｃ−２アダプタを用いてサイズダウンした別の光ファイバ収納ケース（光ファイバ収納ケース１０１と同じ構造）に収納し、この光ファイバ収納ケースで１９インチラックに実装することを余儀なくされている。   Therefore, conventionally, a 19-inch rack is stored in another optical fiber storage case (same structure as the optical fiber storage case 101) that is reduced in size using an S′C-2 adapter that is smaller in size than the SC adapter. However, this optical fiber storage case must be mounted on a 19-inch rack.

この発明は上述の課題を解決するためになされたものである。   The present invention has been made to solve the above-described problems.

この発明の光配線箱は、複数の光アダプタをケース本体の前面の一方向に隣接した状態で配設して取付ける光配線箱において、
前記ケース本体の前記一方向の両端面と前記複数の光アダプタのうちの両端の光アダプタの前記一方向の外面とが面一となるように、前記ケース本体に前記複数の光アダプタを収納する構成であることを特徴とするものである。 The optical wiring box of the present invention is an optical wiring box in which a plurality of optical adapters are disposed and attached in a state adjacent to one direction of the front surface of the case body.
The plurality of optical adapters are housed in the case body such that both end surfaces in the one direction of the case body are flush with outer surfaces in the one direction of the optical adapters at both ends of the plurality of optical adapters. It is characterized by the configuration.

この発明の光配線箱は、前記光配線箱において、前記ケース本体の前面に、前記複数の光アダプタを前記一方向に隣接した状態で配列して取り付けるアダプタ取付部を設け、このアダプタ取付部の前記一方向の両端に、前記複数の光アダプタのうちの両端の光アダプタが前記ケース本体内に収納される部分を嵌合可能な切欠き部を設けると共にこの切欠き部がケース本体の両端面に貫通していることが好ましい。   In the optical wiring box of the present invention, in the optical wiring box, an adapter mounting portion is provided on the front surface of the case body so that the plurality of optical adapters are arranged in a state adjacent to the one direction. Provided at both ends in the one direction are notches that can be fitted into portions where the optical adapters at both ends of the plurality of optical adapters are accommodated in the case body, and the notches are provided at both end surfaces of the case body. It is preferable to penetrate through.

この発明の光配線箱は、前記光配線箱において、前記光アダプタが、前記一方向と直交するＡ方向の両側に突出する取付部を備え、
前記ケース本体が、前記光アダプタの両側の取付部のＡ方向の全長とほぼ同じ幅寸法を有すると共に、このケース本体の前記幅寸法を有する前面に、前記複数の光アダプタを前記一方向に隣接した状態で配列して挿入するアダプタ装着穴部と、このアダプタ装着穴部の前記Ａ方向の両側に前記複数の光アダプタの両側の取付部を前記一方向に隣接した状態で配列して突き当てるアダプタ突当て部と、このアダプタ突当て部に突き当てられた前記複数の光アダプタの両側の取付部を前記一方向に亘って押さえて固定する押え部材と、から構成していることが好ましい。 The optical wiring box of the present invention is provided with mounting portions that protrude on both sides in the A direction orthogonal to the one direction, in the optical wiring box.
The case body has a width that is substantially the same as the overall length in the A direction of the mounting portions on both sides of the optical adapter, and the plurality of optical adapters are adjacent to the front surface of the case body having the width dimension in the one direction. The adapter mounting hole portion to be arranged and inserted in the state of being attached, and the mounting portions on both sides of the plurality of optical adapters are aligned and abutted on both sides of the adapter mounting hole portion in the A direction in a state adjacent to the one direction. It is preferable to comprise an adapter abutting portion and a pressing member for pressing and fixing the mounting portions on both sides of the plurality of optical adapters abutted against the adapter abutting portion in the one direction.

この発明の光配線箱は、前記光配線箱において、前記押え部材の表面側に、前記複数の各光アダプタに対応する線番表示を設けていることが好ましい。   In the optical wiring box of the present invention, in the optical wiring box, it is preferable that a line number display corresponding to each of the plurality of optical adapters is provided on the surface side of the holding member.

この発明の光配線箱は、前記光配線箱において、前記押え部材を、前記複数の光アダプタの取付部のうちの一又は複数箇所の位置で固定具を介して前記アダプタ突当て部に固定することが好ましい。   In the optical wiring box according to the present invention, in the optical wiring box, the holding member is fixed to the adapter abutting portion via a fixture at one or a plurality of positions of the mounting portions of the plurality of optical adapters. It is preferable.

この発明の光配線箱は、前記光配線箱において、前記押え部材を、前記複数の光アダプタの取付部の前記一方向の両外側の位置で固定具を介して前記アダプタ突当て部に固定することが好ましい。   In the optical wiring box according to the present invention, in the optical wiring box, the holding member is fixed to the adapter abutting portion via a fixture at positions on both outer sides in one direction of the mounting portions of the plurality of optical adapters. It is preferable.

以上のごとき課題を解決するための手段から理解されるように、この発明によれば、多数の光配線箱を収納する光モジュールラックは外形寸法が規格化されており、光アダプタの外形寸法も規格化されているために、所望の光アダプタの複数個を収納した光配線箱が微妙な差で光モジュールラックに装着できない場合、この発明の光配線箱はケース本体の一方向の両端面と複数の光アダプタのうちの両端の光アダプタの一方向の外面とを面一とすることによって、ケース本体の一方向の長さを複数の光アダプタの一方向の長さと同じにして最小限に押さえることができるために、上記の所望の光アダプタの複数個を収納した光配線箱を光モジュールラックに装着可能となる。   As can be understood from the means for solving the problems as described above, according to the present invention, the optical module rack that accommodates a large number of optical wiring boxes has standardized external dimensions, and the external dimensions of the optical adapter are also If the optical distribution box containing a plurality of desired optical adapters cannot be installed in the optical module rack due to subtle differences due to the standardization, the optical distribution box of the present invention is connected to both end surfaces of the case body in one direction. Minimizing the length of the case body in one direction to be the same as the length in one direction of the optical adapters by making the outer surfaces of the optical adapters in both directions of the optical adapters flush with each other. Since it can be held down, an optical wiring box containing a plurality of the desired optical adapters can be mounted on the optical module rack.

また、アダプタ取付部の一方向の両端に、ケース本体の両端面に貫通する切欠き部を設けたので、複数の光アダプタのうちの両端の光アダプタが切欠き部に嵌合することによって、前記両端の光アダプタの一方向の外面とケース本体の両端面を面一にできる。   In addition, since the notch portions that penetrate the both end faces of the case body are provided at both ends in one direction of the adapter mounting portion, the optical adapters at both ends of the plurality of optical adapters are fitted into the notch portions, The outer surfaces in one direction of the optical adapters at both ends and the both end surfaces of the case body can be flush with each other.

また、前記光アダプタが前記一方向と直交するＡ方向の両側に突出する取付部を備えている場合、この光アダプタの複数個を前記一方向に隣接した状態で配列してアダプタ装着穴部に挿入して両側の取付部がアダプタ突当て部に突き当てられた後に、複数の光アダプタの両側の取付部がそれぞれ押え部材により前記一方向の全長に亘って押さえて固定されるので、複数の光アダプタの取付作業が容易に且つ短時間で行うことができる。   In addition, when the optical adapter includes mounting portions that protrude on both sides in the A direction orthogonal to the one direction, a plurality of the optical adapters are arranged adjacent to each other in the one direction, and the adapter mounting holes are arranged. After the insertion and the mounting portions on both sides are abutted against the adapter abutting portion, the mounting portions on both sides of the plurality of optical adapters are respectively pressed and fixed over the entire length in the one direction by the pressing member. The optical adapter can be easily attached in a short time.

しかも、上記の押え部材を固定具を用いて固定する箇所は、前記一方向の一又は複数箇所の少ない位置でよいので、簡単に行うことができる。   And since the location which fixes said pressing member using a fixing tool may be a position with few one or several places of the said one direction, it can carry out easily.

また、押え部材は少ない箇所で固定されるために、押え部材の表面に複数の各光アダプタに対応する線番表示を設けることができるので、ケース本体のＡ方向の幅寸法は光アダプタの両側の取付部のＡ方向の全長とほぼ同じ寸法にでき、薄型化を実現できる。しかも、この薄型モジュールの光配線箱であっても複数の光アダプタの線番表示を正面から視認することができる。したがって、この場合は、前記一方向の長さを最小限に押さえると共に前記一方向に直交するＡ方向も狭くできるという相乗効果がある。   In addition, since the presser member is fixed at a small number of locations, wire number indications corresponding to a plurality of optical adapters can be provided on the surface of the presser member. The mounting portion can be made substantially the same size as the entire length in the A direction, and a reduction in thickness can be realized. And even if it is an optical wiring box of this thin module, the line number display of a some optical adapter can be visually recognized from the front. Therefore, in this case, there is a synergistic effect that the length in the one direction can be minimized and the A direction orthogonal to the one direction can be narrowed.

光集合モジュールでは、光配線箱が薄型モジュールであるので、限られた範囲に、上記の光配線箱を増大して多数集合することができる。しかも、各光配線箱は複数の光アダプタの線番表示を正面から視認できるので、隣り合う光配線箱の間に間隔を設ける必要が無く、光配線箱を隣接した状態で配列することができる。結果として、光ファイバを高密度に収納することが可能となる。   In the optical assembly module, since the optical wiring box is a thin module, a large number of the optical wiring boxes can be assembled within a limited range. In addition, since each optical wiring box can visually recognize the line number display of a plurality of optical adapters from the front, it is not necessary to provide a space between adjacent optical wiring boxes, and the optical wiring boxes can be arranged in an adjacent state. . As a result, it becomes possible to store optical fibers at high density.

以下、この発明の実施の形態について図面を参照して説明する。   Embodiments of the present invention will be described below with reference to the drawings.

In addition, both ends of the adapter mounting hole 25 in the second direction are configured to penetrate the upper and lower surfaces of the case main body 19 through the notches 21.

また、前記左、右取付板２３Ｌ，２３Ｒには、アダプタ装着穴部２５の第１方向の両側に複数の光アダプタ３の両側の取付部１１を第２方向に隣接した状態で配列して突き当てるアダプタ突当て面２７が設けられている。   Further, the left and right mounting plates 23L, 23R are arranged so that the mounting portions 11 on both sides of the plurality of optical adapters 3 are arranged adjacent to each other in the second direction on both sides in the first direction of the adapter mounting hole 25.

この実施の形態では、ケース本体１９は、板材を折曲げ成形した分割ケース１９Ａ，１９Ｂと、アダプタ取付部２３の図１において右側部分を構成する右取付板２３Ｒと、から構成される。なお、上記の右取付板２３Ｒは断面Ｌ字形状に折曲げされたものである。   In this embodiment, the case main body 19 is composed of divided cases 19A and 19B formed by bending a plate material, and a right mounting plate 23R constituting the right side portion of the adapter mounting portion 23 in FIG. The right mounting plate 23R is bent into an L-shaped cross section.

また、分割ケース１９Ａはほぼ箱形形状であり、この箱形形状の前面（図１において左斜め下側）にはアダプタ取付部２３の図１において左側部分を構成する左取付板２３Ｌが折曲げ形成されている。さらに、分割ケース１９Ａの箱形形状の図１において上下には前記切欠き部２１の一部を構成する部分を備えた曲げ片２９が前記左取付板２３Ｌと隣接して直交するように設けられている。   Further, the split case 19A has a substantially box shape, and a left mounting plate 23L constituting the left side portion in FIG. 1 of the adapter mounting portion 23 is bent on the front surface (left obliquely lower side in FIG. 1) of the box shape.

また、分割ケース１９Ｂは、分割ケース１９Ａを被蓋する蓋部形状であり、この蓋部形状の図１において上下には前記切欠き部２１の一部を構成する部分を備えた曲げ片３１がほぼ直角に折曲げ形成されている。さらに、蓋部形状の図１において左側縁にはケース取付板３３が第１方向の外側に向けてほぼ直角に折曲げ形成されている。   The split case 19B has a lid shape that covers the split case 19A. In FIG. 1 of the lid shape, a bent piece 31 having a portion constituting a part of the notch portion 21 is provided above and below. It is bent almost at right angles. Further, a case attachment plate 33 is formed at the left side edge in FIG. 1 of the lid shape so as to be bent at a substantially right angle toward the outside in the first direction.

また、上記のアダプタ突当て面２７に突き当てられた複数の光アダプタ３の両側の取付部１１は、押え板３５によりそれぞれ第２方向に亘って押さえて固定されるように構成されている。この実施の形態では、複数の光アダプタ３のうちの第２方向の両端側の２つの光アダプタ３の取付部１１の位置で、取付用ビス１３によってネジ止め固定されるように、上記のアダプタ突当て面２７には前記取付用ビス１３を螺合するための合計４つのネジ孔３７が設けられている。一方、各押え板３５は光アダプタ３の取付部１１の第１方向の長さとほぼ同じ幅寸法であり、隣接した状態で配列された複数の光アダプタ３の取付部１１の第２方向の全長とほぼ同じ長さ寸法であり、押え板３５の長手方向の両端側には、上記の取付用ビス１３を挿通可能な貫通孔３９が設けられている。   Further, the attachment portions 11 on both sides of the plurality of optical adapters 3 that are abutted against the adapter abutting surface 27 are configured to be pressed and fixed in the second direction by the presser plates 35, respectively. In this embodiment, the above adapter is screwed and fixed by the mounting screws 13 at the positions of the mounting portions 11 of the two optical adapters 3 on both ends in the second direction among the plurality of optical adapters 3. The abutting surface 27 is provided with a total of four screw holes 37 for screwing the mounting screws 13 together. On the other hand, each holding plate 35 has substantially the same width as the length in the first direction of the mounting portion 11 of the optical adapter 3, and the total length in the second direction of the mounting portions 11 of the plurality of optical adapters 3 arranged in an adjacent state. The through holes 39 through which the mounting screws 13 can be inserted are provided at both ends in the longitudinal direction of the presser plate 35.

また、上記の押え板３５の表面には、複数の各光アダプタ３に対応する線番表示４１が設けられている。   A wire number display 41 corresponding to each of the plurality of optical adapters 3 is provided on the surface of the pressing plate 35.

さらに、ケース取付板３３は、図４に示されているように多数の光配線箱１を集合して光集合モジュールを構成するための光モジュールラック４３に装着する際に、光モジュールラック４３の光配線箱取付部４５に突き当ててネジ止め固定するものであり、ケース取付板３３の図１において上部には取付用ビス４７を挿通するビス挿通孔４９が設けられている。   Further, as shown in FIG. 4, the case mounting plate 33 is attached to the optical module rack 43 for assembling a large number of optical wiring boxes 1 to form an optical assembly module. A screw insertion hole 49 through which the mounting screw 47 is inserted is provided in the upper part of the case mounting plate 33 in FIG.

図４（Ａ），（Ｂ）を参照するに、光モジュールラック４３は、一般的に板材で一端側に開口部を設けた直方体形状に形成されており、多数の光配線箱１を挿入して装着するための収納部５１が前記開口部に設けられており、各光配線箱１の横幅方向の側面を隣り合うように横並びに並べて収納され、ユニット化される構成である。すなわち、光モジュールラック４３で光集合モジュールが構成されるものである。   Referring to FIGS. 4A and 4B, the optical module rack 43 is generally a plate and is formed in a rectangular parallelepiped shape having an opening on one end side, and a large number of optical wiring boxes 1 are inserted therein. The opening 51 is provided in the opening, and the side surfaces in the horizontal width direction of the respective optical wiring boxes 1 are stored side by side so as to be adjacent to each other and unitized. That is, the optical module rack 43 constitutes an optical assembly module.

この実施の形態では光モジュールラック４３に１２箇所の収納部５１が設けられており、前記光配線箱取付部４５が各収納部５１に設けられている。また、光配線箱取付部４５にはケース取付板３３を固定するためのネジ穴５３が設けられている。したがって、各光配線箱１を光モジュールラック４３に装着するには、光配線箱１を収納部５１に挿入し、ケース取付板３３を光配線箱取付部４５に突き当て、取付用ビス４７をビス挿通孔４９に挿通してネジ穴５３にネジ止め固定する。   In this embodiment, the optical module rack 43 is provided with 12 storage portions 51, and the optical wiring box mounting portions 45 are provided in the storage portions 51. The optical wiring box mounting portion 45 is provided with a screw hole 53 for fixing the case mounting plate 33. Therefore, in order to mount each optical wiring box 1 on the optical module rack 43, the optical wiring box 1 is inserted into the storage part 51, the case mounting plate 33 is abutted against the optical wiring box mounting part 45, and the mounting screw 47 is attached. The screw is inserted into the screw insertion hole 49 and fixed to the screw hole 53 with screws.

また、上記の光モジュールラック４３の外形寸法（外寸）は規格化されており、例えば、ＥＩＡ規格では１９インチラック（図４のラック幅寸法Ｗ０が１９インチ）において、外寸高さＨ０が８８．１ｍｍである。したがって、光モジュールラック４３の構成部材の板厚が１．２ｍｍである場合、内寸高さＨ１は８５．７ｍｍとなる。   Further, the outer dimension (outer dimension) of the optical module rack 43 is standardized. For example, in the EIA standard, the outer dimension height H0 is 19 inch rack (the rack width dimension W0 in FIG. 4 is 19 inches). It is 88.1 mm. Therefore, when the plate thickness of the constituent members of the optical module rack 43 is 1.2 mm, the inner dimension height H1 is 85.7 mm.

上記構成により、ケース本体１９は、右取付板２３Ｒが分割ケース１９Ｂに取付用ビス５５により一体的にネジ止め固定され、分割ケース１９Ｂは例えば分割ケース１９Ａの内部に突設されたシャフト５７の先端のネジ穴に取付用ビス５９により一体的にネジ止め固定され、直方体をなす扁平縦型形状に組み立てられる。この組み立てられたケース本体１９の上下面には光アダプタ３の取付部１１より後部３Ａを嵌合可能な切欠き部２１が形成されると共に、ケース本体１９の前面には複数の光アダプタ３を挿入するためのアダプタ装着穴部２５が形成されることになる。   With the above configuration, the case body 19 has the right mounting plate 23R screwed and fixed integrally to the split case 19B with the mounting screws 55, and the split case 19B is, for example, the tip of the shaft 57 protruding from the split case 19A. The screw holes are integrally fixed to the screw holes by mounting screws 59 and assembled into a flat vertical shape having a rectangular parallelepiped shape. A cutout portion 21 is formed on the upper and lower surfaces of the assembled case body 19 so that the rear portion 3A can be fitted from the attachment portion 11 of the optical adapter 3. A plurality of optical adapters 3 are provided on the front surface of the case body 19. An adapter mounting hole 25 for insertion is formed.

上記のケース本体１９に複数の光アダプタ３を装着するには、複数の光アダプタ３が図１において上下方向に互いに隣接した状態で配列してアダプタ装着穴部２５に挿入されて複数の光アダプタ３の両側の取付部１１がアダプタ突当て面２７に突き当てられた後に、２つの押え板３５が複数の光アダプタ３の両側の取付部１１の前方（図１において左斜め下側）の面に第２方向の全長に亘って押し当てられ、次いで取付用ビス１３が各押え板３５の長手方向の両端側の貫通孔３９、及び光アダプタ３の取付部１１のビス挿通孔１５に挿入されてアダプタ突当て面２７のネジ孔３７にネジ止めすることにより、複数の光アダプタ３の全体がアダプタ突当て面２７に固定されることとなる。   In order to mount the plurality of optical adapters 3 on the case body 19, the plurality of optical adapters 3 are arranged in the state of being adjacent to each other in the vertical direction in FIG. After the mounting portions 11 on both sides of 3 are abutted against the adapter abutting surface 27, the two presser plates 35 are surfaces in front of the mounting portions 11 on both sides of the plurality of optical adapters 3 (left diagonally lower side in FIG. 1). Then, the mounting screws 13 are inserted into the through holes 39 on both ends in the longitudinal direction of the holding plates 35 and the screw insertion holes 15 of the mounting portion 11 of the optical adapter 3. Then, the whole of the plurality of optical adapters 3 is fixed to the adapter abutting surface 27 by screwing into the screw hole 37 of the adapter abutting surface 27.

すなわち、アダプタ突当て面２７には４つの少数のネジ孔３７を設けるだけでよいので、ネジ孔加工の作業時間が短くて済むと共に、４つの取付用ビス１３でネジ止めするだけでよいので、複数の光アダプタ３をアダプタ突当て面２７に装着することが容易に短時間で完了する。   That is, since only a small number of four screw holes 37 need be provided on the adapter abutting surface 27, the work time for screw hole processing can be shortened, and only screwing with the four mounting screws 13 is required. The mounting of the plurality of optical adapters 3 on the adapter abutting surface 27 is easily completed in a short time.

なお、上記の押え板３５を取付用ビス１３でネジ止めする箇所は、前述したように第２方向の両端側の光アダプタ３の取付部１１の位置に限らず、任意の光アダプタ３の取付部１１の位置であっても構わない。あるいは、複数の光アダプタ３の第２方向の長さのほぼ中央に位置する１つの光アダプタ３の取付部１１の位置で、押え板３５の長手方向のほぼ中央の１つの貫通孔３９を介して取付用ビス１３によりネジ止めしても構わない。あるいは、上記の光アダプタ３の取付部１１のビス挿通孔１５を用いずに、別途に例えばビス挿通孔を備えたブロックなどの介在部材を前記複数の光アダプタ３の第２方向の両外側に設け、前記介在部材に設けたビス挿通孔に取付用ビス１３を挿通して押え板３５をアダプタ突当て面２７にネジ止めしても構わない。   It should be noted that the position where the holding plate 35 is screwed with the mounting screw 13 is not limited to the position of the mounting portion 11 of the optical adapter 3 on both ends in the second direction, as described above, and any optical adapter 3 can be mounted. The position of the part 11 may be used. Alternatively, at the position of the attachment portion 11 of one optical adapter 3 located at the approximate center of the length in the second direction of the plurality of optical adapters 3, the one through hole 39 at the approximate center in the longitudinal direction of the press plate 35 The mounting screws 13 may be used for screwing. Alternatively, without using the screw insertion holes 15 of the mounting portion 11 of the optical adapter 3, intervening members such as blocks provided with screw insertion holes are provided on both outer sides in the second direction of the plurality of optical adapters 3. The mounting plate 13 may be inserted into a screw insertion hole provided in the interposed member, and the holding plate 35 may be screwed to the adapter abutting surface 27.

また、上記のように長い押え板３５により少数の取付用ビス１３でネジ止めするので、押え板３５の表面には複数の各光アダプタ３に対応する線番表示４１が設けられる。このように、線番表示４１が光アダプタ３のアダプタ差込穴９の両側に表示されるので、線番表示４１を正面から視認できる。   Further, since a small number of mounting screws 13 are screwed by the long pressing plate 35 as described above, wire number displays 41 corresponding to the plurality of optical adapters 3 are provided on the surface of the pressing plate 35. Thus, since the line number display 41 is displayed on both sides of the adapter insertion hole 9 of the optical adapter 3, the line number display 41 can be visually recognized from the front.

したがって、光配線箱１は、前述したように第２方向の長さを最小限に押さえることができると共に、ケース本体１９の第１方向の横幅が光アダプタ３の両側の取付部１１の第１方向の全長とほぼ同じ寸法にして第１方向も狭く、すなわち薄型化を実現できるという相乗効果がある。   Accordingly, the optical wiring box 1 can minimize the length in the second direction as described above, and the width of the case body 19 in the first direction is the first of the mounting portions 11 on both sides of the optical adapter 3. There is a synergistic effect that the first direction is made narrower, that is, the thickness can be reduced, by making the dimension substantially the same as the total length in the direction.

なお、この実施の形態の光配線箱１は、光モジュール、パッチパネル、アダプタパネル等のように複数個のアダプタを連結させて固定する製品に幅広く適用されるものである。   The optical wiring box 1 of this embodiment is widely applied to products that connect and fix a plurality of adapters such as an optical module, a patch panel, an adapter panel, and the like.

以上のことから、第２方向に隣接した状態で並べられた複数の光アダプタ３がアダプタ装着穴部２５に挿入されるとき、前記複数の光アダプタ３のうちの最上下の光アダプタ３の後部３Ａがケース本体１９の切欠き部２１に嵌合するので、複数の光アダプタ３のうちの上下面はケース本体１９の上下面と面一となる。つまり、隣接した状態で並べられた複数の光アダプタ３の第２方向の全長と、ケース本体１９の上下面間の外寸高さＨ３〔図３（Ｃ）を参照〕とは同じ寸法になる。   From the above, when the plurality of optical adapters 3 arranged adjacent to each other in the second direction are inserted into the adapter mounting hole 25, the rear part of the lowermost optical adapter 3 among the plurality of optical adapters 3. Since 3A fits into the notch 21 of the case body 19, the upper and lower surfaces of the plurality of optical adapters 3 are flush with the upper and lower surfaces of the case body 19. That is, the overall length in the second direction of the plurality of optical adapters 3 arranged adjacent to each other is the same as the outer dimension height H3 between the upper and lower surfaces of the case body 19 (see FIG. 3C). .

光アダプタ３は種々の寸法に規格化されており、この実施の形態の光配線箱１に光アダプタ３として例えば９個のＳＣアダプタを装着してカプラモジュール（１×８分岐）とした場合は、１個のＳＣアダプタの高さが９．４ｍｍであるので９個のＳＣアダプタの高さ全長と図３（Ｃ）に示されている光配線箱１の外寸高さＨ３が同一の８４．６ｍｍとなる。   The optical adapter 3 is standardized in various dimensions. When, for example, nine SC adapters are attached to the optical wiring box 1 of this embodiment as the optical adapter 3 to form a coupler module (1 × 8 branch). Since the height of one SC adapter is 9.4 mm, the total height of the nine SC adapters and the outer dimension height H3 of the optical wiring box 1 shown in FIG. 6 mm.

したがって、前述したようにＥＩＡ規格における１９インチラックの光モジュールラック４３では内寸高さＨ１が８５．７ｍｍであるのに対して上記の光配線箱１の外寸高さＨ３が８４．６ｍｍであるので、９個のＳＣアダプタを用いたカプラモジュール（１×８分岐）が光モジュールラック４３に実装できることになる。   Therefore, as described above, in the optical module rack 43 of the 19-inch rack in the EIA standard, the inner dimension height H1 is 85.7 mm, whereas the outer dimension height H3 of the optical wiring box 1 is 84.6 mm. Therefore, a coupler module (1 × 8 branch) using nine SC adapters can be mounted on the optical module rack 43.

図４を参照するに、上記の９個のＳＣアダプタを実装した光配線箱１は、光モジュールラック４３の１２箇所の各収納部５１に挿入され、ケース取付板３３を光配線箱取付部４５に突き当ててから取付用ビス４７により各収納部５１のネジ穴５３にネジ止め固定される。１２個の光配線箱１が光モジュールラック４３の各収納部５１に各光配線箱１の扁平縦型の横幅方向の側面が隣り合うように、換言すれば第１方向に横並びに並べられて光集合モジュールが構成される。   Referring to FIG. 4, the optical wiring box 1 mounted with the nine SC adapters is inserted into each of the 12 storage portions 51 of the optical module rack 43, and the case mounting plate 33 is connected to the optical wiring box mounting portion 45. After being abutted, the mounting screws 47 are fixed to the screw holes 53 of the storage portions 51 with screws. The twelve optical wiring boxes 1 are arranged side by side in the first direction so that the horizontal and vertical side surfaces of the optical wiring boxes 1 are adjacent to the storage portions 51 of the optical module rack 43. An optical assembly module is configured.

なお、光集合モジュールでは、この実施の形態の光配線箱１が薄型モジュールであるので、限られた範囲の光モジュールラック内に上記の光配線箱を増大して多数集合できる。しかも、各光配線箱１は複数の光アダプタ３の線番表示４１を正面から視認できるので、隣り合う光配線箱１の間に間隔を設ける必要が無く、光配線箱１を隣接した状態で配列でき、光ファイバを高密度に収納することが可能である。   In the optical assembly module, since the optical wiring box 1 of this embodiment is a thin module, a large number of the optical wiring boxes can be assembled in an optical module rack in a limited range. Moreover, since each optical wiring box 1 can visually recognize the wire number display 41 of the plurality of optical adapters 3 from the front, it is not necessary to provide a space between the adjacent optical wiring boxes 1, and the optical wiring boxes 1 are adjacent to each other. The optical fibers can be arranged at high density.

図５を参照するに、この実施の形態に係る光配線箱１を装着した光集合モジュールでは、例えば、局舎６１内の光ケーブル６３から単心光ファイバ５に分岐され、これらの各単心光ファイバ５の先端は光コネクタ７にて成端される。この成端した各光コネクタ７は光配線箱１の対応する光アダプタ３の図５において左側のアダプタ差込穴９（図１を参照）に差し込まれて接続される。光配線箱１のケース本体１９の内部では、光アダプタ３の図５において右側のアダプタ差込穴（図示省略）に他の光コネクタ１７が差し込まれている。各光コネクタ１７には単心光ファイバ５が成端されており、これらの各単心光ファイバ５はケース本体１９の図５において右側の光コネクタ６５に接続されている。   Referring to FIG. 5, in the optical assembly module equipped with the optical wiring box 1 according to this embodiment, for example, the optical cable 63 in the office building 61 is branched into the single optical fiber 5, and each of these single optical fibers is The tip of the fiber 5 is terminated by an optical connector 7. Each terminated optical connector 7 is inserted into and connected to an adapter insertion hole 9 (see FIG. 1) on the left side in FIG. 5 of the corresponding optical adapter 3 of the optical wiring box 1. Inside the case main body 19 of the optical wiring box 1, another optical connector 17 is inserted into an adapter insertion hole (not shown) on the right side of the optical adapter 3 in FIG. 5. Single optical fibers 5 are terminated at each optical connector 17, and each single optical fiber 5 is connected to an optical connector 65 on the right side of the case body 19 in FIG. 5.

一方、光モジュールラック４３には光配線箱１の複数の光コネクタ６５と接続される複数の光アダプタ６７が設けられており、光配線箱１が取付用ビス４７（図１を参照）で光モジュールラック４３の収納部５１の光配線箱取付部４５に取り付けられるときに、各光コネクタ６５が対応する各光アダプタ６７に差し込まれて接続されるように構成されている。さらに、各光アダプタ６７には加入者側の単心光ファイバ５に成端された光コネクタ６９が接続、抜脱可能となっている。以上のように、光配線箱１は外部の光ファイバ５が光コネクタ７，６９及び光アダプタ３，６７によって切り替え自在となっている。   On the other hand, the optical module rack 43 is provided with a plurality of optical adapters 67 connected to the plurality of optical connectors 65 of the optical wiring box 1, and the optical wiring box 1 is optically connected with mounting screws 47 (see FIG. 1). Each optical connector 65 is configured to be inserted and connected to a corresponding optical adapter 67 when it is attached to the optical wiring box attachment portion 45 of the storage portion 51 of the module rack 43. Furthermore, an optical connector 69 terminated on the subscriber-side single optical fiber 5 can be connected to and disconnected from each optical adapter 67. As described above, in the optical wiring box 1, the external optical fiber 5 can be switched by the optical connectors 7 and 69 and the optical adapters 3 and 67.
