【0001】
【発明の属する技術分野】
本発明は、光ファイバの融着接続部等の光部品を固定する光部品ホルダであって、光部品を確実に固定し、振動などによる脱落を防止し得る光部品ホルダに関するものである。
【0002】
【従来の技術】
光配線盤等の架体や光接続箱等にあっては光ファイバ同士の融着接続部を、架体や箱のフレーム等に取り付けた専用のホルダによって、取り出し可能に保持することが広く行われている。
【0003】
前記ホルダとしては、図15から図17に示すものが提供されている。図に示すホルダ50は、プラスチック等の合成樹脂による一体成形品であることが一般的であり、底板51上に、突壁状の保持片52、53が複数並列に配列させて突設された構造になっている。配列の一方の端に位置する保持片53(以下、端部壁と称する場合がある)を除く各保持片52は、底板51から立ち上げられた主壁部52aと、この主壁部52aから、端壁部53方向に張り出された弾性片である押え片52bとを有している。図中符号59は、光ファイバ57同士の融着接続部であり、このホルダ50は、隣り合う保持片52、52間(あるいは保持片52、53間)に挿入された融着接続部59を、隣り合う一方の保持片52の押え片52bが他方の保持片52の主壁部52a(または保持片53)に付勢力を以って押え込むことで保持するようになっている。なお、保持片53は底板51上に立ち上げられた壁状になっている。また、図中、符号55は保持片52、52間(あるいは保持片52、53間)にて底板51に形成された開口部である。符号54は、底板51の下面側に突設された弾性爪であり、ホルダ50は、光配線盤のフレーム等の固定用部材62に弾性爪54を係合または嵌合させることで、簡単に取り付けることができる。また、符号60は、ホルダ50を固定用部材62に固定するための両面テープである。
【0004】
【発明が解決しようとする課題】
ところで、前述のホルダ50は、隣り合う保持片52間(あるいは保持片52、53間)に融着接続部59を着脱自在に保持するようになっており、振動等によって融着接続部59が外部へ抜け出してしまうことを防止するために、上蓋61を被せることが多い。しかしながら、上蓋61を要する構成では、部品点数が多く、コスト面で不利であるといった不満があった。また、固定すべき融着接続部の数やサイズ等に対応するには、多品種のホルダ50や上蓋61を用意する必要があり、この点でコスト面で不利になるといった不満があった。
【0005】
本発明は、上記事情に鑑みてなされたものであり、第一の目的は、光部品が抜け出さず、かつ構成を簡単にした光部品ホルダを提供することにある。
また、第二の目的は、光部品の取り付け箇所を対象とする機器に応じて個数を選択できるようにした光部品ホルダを提供することにある。
【0006】
【課題を解決するための手段】
上記の課題を解決するために、請求項1に記載した発明は、光部品を固定する光部品ホルダであって、前記光部品を挟み込むための押え片が底板上に複数配列して突設され、前記各押え片間が前記光部品の保持領域とされると共に、該押え片に該光部品保持領域外への前記光部品の抜出を防止する防止部が設けられ、全体が合成樹脂によって一体成形された一部品であり、前記底板に前記押え片間に位置させて切断用切込みが形成されていることを特徴とする。
【0007】
本発明に係る光部品ホルダによれば、光部品を押え片間に挿入して保持させた際に、この光部品が防止部によって外部に抜出するのが防止される。すなわち、このホルダは、光部品を各押え片間に入れて使用する。この際、光部品は、主壁部と押え壁部とによって挟持されることによって定位置に保持される。この場合、光部品は防止部によって外部への抜出が防止される。
また、この発明に係る光部品ホルダによれば、ホルダの取り付けられる機器に応じて、光部品の取付部の個数を選択することが出来、切断用切込みをもって切断することにより、機器に応じて光部品ホルダの取付個数を選択することが可能である。
【0008】
請求項2記載の発明は、左右一対の押え片が隣接する押え片の前記防止部が互いに接近、離間する方向へ弾性変形可能に構成されていることを特徴とする。
【0009】
この発明に係る光部品ホルダによれば、押え片を弾性変形させることによって、光部品の保持領域への挿入、離脱が容易になされる。
【0012】
【発明の実施の形態】
図1から図8は、本発明の一実施形態として示した光部品ホルダを示す図である。これらの図において、光ホルダ1は、プラスチック等の合成樹脂による一体成形品であり、底板2とこの底板2上に複数配列して突設された押え片3とを主な構成要素とする。
【0013】
底板2は、ほぼ矩形状に形成された厚さ数mm程度の平板状部であって、その中央部には複数の矩形の開口部4が配列形成されている。隣り合う開口部4の間には、底板2の一部である横連結部5が形成されており、複数本の横連結部5によって底板2の左右(図3左右)両側の縦連結部6間が連結されている。前記縦連結部6は底板2の一部を形成するものであり、底板2の左右両側にて、底板2の縦方向(図3上下方向)に延在している。押え片3は、各縦連結部6上にて横連結部5と縦連結部6との連結部間に立ち上げるようにして形成されている。左右の押え片3は一直線上に主壁部7が位置するように配置され、開口部4を介して互いに対向するように設けられている。
【0014】
押え片3は縦連結部6に連設された主壁部7と、この主壁部7の内端側に突設された押え壁部8aと、外端側に突設された押え壁部8bとからなっている。これら押え壁部8a、8bは主壁部7の同一の側面側、具体的には側板10の側に主壁部7から斜めに折り曲げて形成されている。そして、これらの壁部の内端側に設けられた押え壁部8aには、その上端にさらに押え壁部8aの前方へ突出し、光部品13の抜出を防止する防止部9が形成されている。ここでは光部品13として光ファイバ19同士の融着接続部を採用しているため、以下、光部品13を融着接続部13と称する場合がある。
【0015】
また、底板2の一端には、側板10が設けられている。また、底板2の下面には機器架体等の固定用ピン11が設けられている。また、このピン11にはその中央部に底板2も含めて貫通する貫通孔16が形成されている。また、底板2の左右の縦連結部6に各押え片3に沿って切断用切込み12が形成されている。この切断用切込み12によって、縦連結部6の底板2が薄肉部となっており、この部分において切り離すことが可能となっている。
【0016】
また、図9において、このホルダ1で保持する光部品である光ファイバ19の融着接続部13を示している。この融着接続部13は、多心光ファイバ19(ここでは光ファイバテープ心線)の融着接続部13であって、楕円の断面輪郭を持って一方向に延びる形状となっている。
【0017】
また、図12は、このホルダ1が取り付けられる機器架体等の取付部18の要部を示しており、取付部18にはホルダ1を取り付けるための貫通孔14が4つ形成されている。このホルダ1を機器に取り付けるには、図13に示すように、取付け冶具15を用いる。この取付け冶具15は、冶具本体15aに操作杆16を設けてなるものである。冶具本体15aにはその下端部に、嵌合部17が形成されている。嵌合部17は、押え片3間に挿入したときに、嵌合部17が押え片3間に挟持されて、ホルダ1を相対的に保持できるようになっている。
【0018】
この操作杆16をホルダ1の押え片3間に挿入して、図14に示すように保持して機器の本体に対向させ、固定用ピン11を貫通孔14に冶具15によって圧入して、ホルダ1に固定する。このように、本体に光ホルダ1が上体に固定された状態においては、ピン11が貫通孔14に密に嵌合され、光ホルダ1が不用意に脱落することはない。
【0019】
そして、このホルダ1に光ファイバ19の融着接続部13を保持させるには、図9に示すように融着接続部13を把持し、これを図に示すように側板10と押え片3間又は押え片3同士間に挿入する。この際、この光部品を光ホルダ1の中に挿入すると、この押え片3の押え壁部8a、8bは底板2に対してその上端部側が拡開する方向に弾性変形し、この融着接続部13が挿入可能となる。
【0020】
そして、これを底板2に当接する位置まで進入させた際に、弾性変形していた押え壁部8a、8bのうち、防止部9が弾性復帰し、融着接続部13の上方に至ることになる。この状態において、押え片3の主壁部7の先端部が融着接続部13の側面に当接し、融着接続部13の軸方向への移動を阻止する。また、弾性復帰した防止部9が融着接続部13上面に当接又は融着接続部13の上方に僅かに間隙をあけて位置し、この融着接続部13の外部への抜出を防止する。このようにして、図10に示すように、側板10と押え片3の間、そして、押え片3同士の間に必要数の融着接続部13を挿入する。かくして、保持作業が完了する。
【0021】
上記の構成からなる光ホルダ1においては、押え壁部8a、8bが融着接続部13の側部に当接するので、融着接続部13は外部の力が加わった場合にも軸方向へ移動することはない。特に、一つの融着接続部13に対し、主壁部7と押え壁部8a、8bが一対あり、各押え片3両端に押え壁部8a、8bが設けられているので、計4箇所でその側面が保持されることになる。
【0022】
そして、この融着接続部13は、一方の側面が隣接する押え片3の主壁部7又は側板10に当接し、この主壁部7又は側板10に対して押え片3の押え壁部8a、8bが4箇所において側面から当接し、これを確実に保持することになる。よって、融着接続部13が軸方向へ移動することはない。さらに、防止部9が融着接続部13の上方に位置するので、振動等によっても融着接続部13が外方へ抜け出すことが防止される。また、このホルダ1においては、従来のように別部材蓋を設けなくても抜け出しを防止できるので、構成が簡単である。
【0023】
さらに、この実施の形態では、防止部9下面(底板2に臨む面)から押え壁部8a、8bの先端面に連続する面が、中実スリーブ状の融着接続部13の外周面にほぼ一致する湾曲面になっており、この湾曲面の内側に融着接続部13が入り込むようなるため、融着接続部13との接触摩擦抵抗が好適に確保され、融着接続部13の位置ずれを防止できる。防止部9と融着接続部13との間には若干隙間があっても良い。防止部9は、融着接続部13を底板2に押圧する訳ではないので、融着接続部13には、底板2に押さえ付けるような力による歪が生じず、光特性が安定に維持される。
【0024】
また、上記のように光ホルダ1に固定された光ファイバ融着接続部13をこのホルダ1から取り外す際には、このホルダ1の防止部9を融着接続部13から離間する方向に弾性変形させて後退させ、これを取り出す。弾性変形させることによって、側面の保持と上の方の抜出防止を同時に解除でき、容易に取り外しが可能である。
【0025】
また、このホルダにおいては、縦連結部6を切断用切込み12において切り離すことによって、各種選択することが出来る。よって、装置のスペースファクターの向上を図ることができる。
【0026】
なお、上記の実施の形態においては、光部品として光ファイバ19の融着接続部13を例として挙げたが、この融着接続部13は融着接続部13に限られず、他の各種光部品であってもよい。また、押え片3の形状は、上記の実施の形態に限られることなく、光部品のサイズ・形状に応じて適宜変更可能である。
【0027】
【発明の効果】
以上説明したように、本発明によれば、以下の効果が得られる。
発明によれば、押え片に防止部を設けたので、光部品が外部へ抜け出すのを確実に防止することができる。
また、ホルダを取り付ける機器に応じて、光部品の取付部の数を適宜選択できるので、スペースファクターの向上を図ることができる。
【0028】
また、請求項2に係る発明によれば、押え片を弾性変形可能に構成したので、光部品の固定又はその離脱作業を容易に行うことができる。

DETAILED DESCRIPTION OF THE INVENTION
1 to 8 are views showing an optical component holder shown as an embodiment of the present invention. In these drawings, the optical holder 1 is an integrally molded product made of a synthetic resin such as plastic, and includes a bottom plate 2 and a plurality of presser pieces 3 arranged in a protruding manner on the bottom plate 2 as main components.
[0013]
The bottom plate 2 is a flat plate portion having a thickness of about several millimeters formed in a substantially rectangular shape, and a plurality of rectangular openings 4 are arranged and formed in the central portion thereof. Between the adjacent opening parts 4, the horizontal connection part 5 which is a part of the baseplate 2 is formed, and the vertical connection part 6 on both the right and left (FIG. 3 left and right) both sides of the baseplate 2 by the multiple horizontal connection parts 5. The space is connected. The vertical connection portion 6 forms a part of the bottom plate 2 and extends in the vertical direction of the bottom plate 2 (vertical direction in FIG. 3) on both the left and right sides of the bottom plate 2. The presser piece 3 is formed so as to rise between the connecting portions between the horizontal connecting portion 5 and the vertical connecting portion 6 on each vertical connecting portion 6. The left and right presser pieces 3 are arranged so that the main wall portion 7 is positioned on a straight line, and are provided to face each other through the opening 4.
[0014]
The presser piece 3 includes a main wall portion 7 connected to the vertical connecting portion 6, a presser wall portion 8a protruding from the inner end side of the main wall portion 7, and a presser wall portion protruding from the outer end side. 8b. These holding wall portions 8a and 8b are formed by being bent obliquely from the main wall portion 7 on the same side surface side of the main wall portion 7, specifically, on the side plate 10 side. The holding wall 8a provided on the inner end side of these wall portions is formed with a prevention portion 9 that protrudes further forward of the pressing wall portion 8a at the upper end thereof and prevents the optical component 13 from being pulled out. Yes. Here, since the fusion splicing part between the optical fibers 19 is employed as the optical component 13, the optical component 13 may be hereinafter referred to as a fusion splicing part 13.
[0015]
A side plate 10 is provided at one end of the bottom plate 2. A fixing pin 11 such as a device frame is provided on the lower surface of the bottom plate 2. Further, the pin 11 is formed with a through hole 16 penetrating through the center of the pin 11 including the bottom plate 2. Further, cutting cuts 12 are formed along the presser pieces 3 in the left and right vertical connecting portions 6 of the bottom plate 2. By this cutting notch 12, the bottom plate 2 of the vertical connecting portion 6 is a thin portion, and can be cut off at this portion.
[0016]
FIG. 9 shows the fusion splicing portion 13 of the optical fiber 19 that is an optical component held by the holder 1. The fusion splicing portion 13 is a fusion splicing portion 13 of a multi-core optical fiber 19 (here, an optical fiber ribbon), and has a shape extending in one direction with an elliptical cross-sectional outline.
[0017]
FIG. 12 shows a main part of an attachment part 18 such as a device frame to which the holder 1 is attached. The attachment part 18 has four through holes 14 for attaching the holder 1. In order to attach the holder 1 to an apparatus, an attachment jig 15 is used as shown in FIG. The attachment jig 15 is formed by providing an operation rod 16 on a jig body 15a. A fitting part 17 is formed at the lower end of the jig body 15a. When the fitting portion 17 is inserted between the presser pieces 3, the fitting portion 17 is sandwiched between the presser pieces 3 so that the holder 1 can be relatively held.
[0018]
The operating rod 16 is inserted between the presser pieces 3 of the holder 1 and held as shown in FIG. 14 so as to face the main body of the device. The fixing pin 11 is press-fitted into the through-hole 14 with the jig 15, and the holder Fix to 1. Thus, in a state where the optical holder 1 is fixed to the upper body in the main body, the pins 11 are closely fitted into the through holes 14 and the optical holder 1 does not fall off carelessly.
[0019]
In order to hold the fusion splicing portion 13 of the optical fiber 19 in the holder 1, the fusion splicing portion 13 is gripped as shown in FIG. 9, and this is shown in FIG. 9 between the side plate 10 and the presser piece 3. Alternatively, it is inserted between the presser pieces 3. At this time, when the optical component is inserted into the optical holder 1, the presser wall portions 8 a and 8 b of the presser piece 3 are elastically deformed in the direction in which the upper end side is expanded with respect to the bottom plate 2. The part 13 can be inserted.
[0020]
And when this is made to approach to the position which contact | abuts to the baseplate 2, the prevention part 9 will elastically return among the press wall parts 8a and 8b which were elastically deformed, and it will reach the upper part of the fusion splicing part 13. Become. In this state, the front end portion of the main wall portion 7 of the presser piece 3 comes into contact with the side surface of the fusion splicing portion 13 to prevent the fusion splicing portion 13 from moving in the axial direction. Moreover, the prevention part 9 that has returned to elasticity is located on the upper surface of the fusion splicing part 13 or located slightly above the fusion splicing part 13 to prevent the fusion splicing part 13 from being pulled out to the outside. To do. In this way, as shown in FIG. 10, the necessary number of fusion splicing portions 13 are inserted between the side plate 10 and the presser piece 3 and between the presser pieces 3. Thus, the holding operation is completed.
[0021]
In the optical holder 1 having the above configuration, the holding wall portions 8a and 8b abut against the side portion of the fusion splicing portion 13, so that the fusion splicing portion 13 moves in the axial direction even when an external force is applied. Never do. In particular, since there is a pair of the main wall portion 7 and the presser wall portions 8a and 8b with respect to one fusion splicing portion 13, and the presser wall portions 8a and 8b are provided at both ends of each presser piece 3, there are a total of four locations. That side will be held.
[0022]
The fusion splicing portion 13 abuts the main wall portion 7 or the side plate 10 of the holding piece 3 whose one side surface is adjacent, and the holding wall portion 8a of the holding piece 3 with respect to the main wall portion 7 or the side plate 10. , 8b come into contact with each other at the four positions from the side, and are securely held. Therefore, the fusion splicing part 13 does not move in the axial direction. Furthermore, since the prevention part 9 is located above the fusion splicing part 13, it is prevented that the fusion splicing part 13 slips out by vibrations or the like. Further, the holder 1 can be prevented from coming out without providing a separate member lid as in the prior art, so that the configuration is simple.
[0023]
Furthermore, in this embodiment, the surface that continues from the lower surface of the prevention portion 9 (the surface facing the bottom plate 2) to the front end surfaces of the presser wall portions 8a and 8b is substantially on the outer peripheral surface of the solid sleeve-like fusion splicing portion 13. Since the fusion-bonding portion 13 enters inside the curved surface, the contact friction resistance with the fusion-connection portion 13 is preferably ensured, and the position of the fusion-connection portion 13 is displaced. Can be prevented. There may be a slight gap between the preventing portion 9 and the fusion splicing portion 13. Since the preventing portion 9 does not press the fusion splicing portion 13 against the bottom plate 2, the fusion splicing portion 13 is not distorted by a force that presses against the bottom plate 2, and the optical characteristics are stably maintained. The
[0024]
When the optical fiber fusion splicing portion 13 fixed to the optical holder 1 is removed from the holder 1 as described above, the prevention portion 9 of the holder 1 is elastically deformed in a direction away from the fusion splicing portion 13.
