Description

本発明は、素線ホルダ及びこの素線ホルダを用いた光ファイバの接続方法に関する。   The present invention relates to a strand holder and an optical fiber connection method using the strand holder.

従来、メカニカルスプライスを内蔵する光コネクタが知られている。このメカニカルスプライスの先端には、短尺光ファイバが内蔵されたフェルールが保持されている。そして、被覆の除去により露出させた光ファイバの先端を切断する処理（端末処理）を施した光ファイバ素線の先端をメカニカルスプライスの後端から挿入し、光ファイバの端面を短尺光ファイバの端面に突き合わせた後、この突き合わせ部分を固定することによって、光コネクタに光ファイバが接続される（例えば特許文献１参照）。
特開平１１−１６０５６３号公報 Conventionally, an optical connector incorporating a mechanical splice is known. A ferrule containing a short optical fiber is held at the tip of the mechanical splice. And the front-end | tip of the optical fiber strand which performed the process (terminal process) which cut | disconnected the front-end | tip of the optical fiber exposed by the removal of a coating is inserted from the rear end of a mechanical splice, and the end surface of an optical fiber is made into the end surface of a short optical fiber Then, the optical fiber is connected to the optical connector by fixing the butt portion (see, for example, Patent Document 1).
JP-A-11-160563

ところで、上述した光コネクタに光ファイバを接続する場合、端末処理後にメカニカルスプライスに挿入される光ファイバの撓み量の管理が重要となる。例えば、光ファイバの撓みが過大になると、短尺光ファイバとの突き合わせ時に光ファイバの端面に大きな荷重がかかってしまう。そのため、接続損失が増大し、良好な接続が得られにくいといった問題が生じ得る。   By the way, when an optical fiber is connected to the optical connector described above, it is important to manage the amount of bending of the optical fiber that is inserted into the mechanical splice after terminal processing. For example, if the bending of the optical fiber becomes excessive, a large load is applied to the end face of the optical fiber at the time of matching with the short optical fiber. As a result, the connection loss increases, and it may be difficult to obtain a good connection.

本発明は、上記課題の解決のためになされたものであり、光コネクタと光ファイバとの良好な接続を可能とする素線ホルダ、及びこの素線ホルダを用いた光ファイバの接続方法を提供することを目的とする。   The present invention has been made to solve the above-described problems, and provides a strand holder that enables good connection between an optical connector and an optical fiber, and a method of connecting an optical fiber using the strand holder. The purpose is to do.

上記課題の解決のため、本発明に係る素線ホルダは、光ファイバ素線を保持するための素線ホルダであって、光ファイバ素線の先端側が載置される溝部が形成された素線載置部と、光ファイバ素線の先端側を溝部に押さえ付ける開閉自在の素線押さえ部と、溝部の長手方向に対して素線押さえ部側に傾斜するように形成され、光ファイバ素線の基端側が載置される傾斜載置部とを備えたことを特徴としている。   In order to solve the above-mentioned problems, a strand holder according to the present invention is a strand holder for holding an optical fiber, and is formed with a groove portion on which a tip side of the optical fiber is placed. A mounting portion, an openable / closable strand pressing portion that presses the distal end side of the optical fiber strand against the groove portion, and an optical fiber strand formed so as to be inclined toward the strand pressing portion side with respect to the longitudinal direction of the groove portion. And an inclined placement portion on which the base end side is placed.

この素線ホルダでは、傾斜載置部に光ファイバ素線の基端側を押し付けることにより、光ファイバ素線の応力を利用して、容易に光ファイバ素線の先端側を素線載置部の溝部に載置することが可能となっている。また、素線押さえ部によって光ファイバ素線の先端側を溝部に固定できるので、端末処理を施した後、光ファイバをメカニカルスプライス内の短尺光ファイバに突き合わせる際に、素線押さえ部を光ファイバの撓みの支点とすることができる。これにより、光コネクタ内での光ファイバの撓み量を管理することが可能となり、光コネクタと光ファイバとの良好な接続を実現できる。   In this strand holder, by pressing the proximal end side of the optical fiber strand against the inclined placement portion, the distal end side of the optical fiber strand can be easily moved to the strand placement portion using the stress of the optical fiber strand. It can be placed in the groove portion. In addition, since the tip end side of the optical fiber can be fixed to the groove by the wire pressing part, the optical fiber holding part can be optically connected to the short optical fiber in the mechanical splice after the end treatment. It can be a fulcrum for the deflection of the fiber. Thereby, it becomes possible to manage the amount of bending of the optical fiber in the optical connector, and a good connection between the optical connector and the optical fiber can be realized.

また、素線載置部と傾斜載置部との間には、光ファイバ素線の基端側を長手方向に沿って挟持する開閉自在な素線挟持部が設けられていることが好ましい。こうすると、端末処理の際に光ファイバ素線をよりしっかりと保持できる。一方で、光コネクタに光ファイバを接続した後は、素線挟持部を開けることにより、素線ホルダから光ファイバ素線を簡単に取り外すことができる。   Moreover, it is preferable that an openable and closable element pinching part for holding the proximal end side of the optical fiber element along the longitudinal direction is provided between the element placing part and the inclined placing part. If it carries out like this, an optical fiber strand can be held more firmly at the time of terminal processing. On the other hand, after the optical fiber is connected to the optical connector, the optical fiber strand can be easily removed from the strand holder by opening the strand clamping portion.

また、素線載置部には、タック性を有する材料が付着していることが好ましい。この場合、素線押さえ部を閉じたときに、タック性によって素線押さえ部が素線載置部に仮止めされるので、光ファイバ素線の先端側の固定を容易に行うことができる。   Moreover, it is preferable that the material which has tackiness adheres to the strand mounting part. In this case, when the strand holding portion is closed, the strand holding portion is temporarily fixed to the strand placing portion due to tackiness, so that the distal end side of the optical fiber strand can be easily fixed.

また、素線載置部、素線押さえ部、傾斜載置部、及び素線挟持部は、タック性を有する材料によって一体成型されていることが好ましい。この場合も、タック性によって素線押さえ部が素線載置部に仮止めされるので、素線押さえ部による光ファイバ素線の先端側の固定を容易に行うことができる。また、一体成型により、素線ホルダの製造コストを低減できる。   Moreover, it is preferable that the strand placing part, the strand holding part, the inclined placing part, and the strand holding part are integrally formed of a material having tackiness. Also in this case, since the strand pressing portion is temporarily fixed to the strand placing portion due to tackiness, the distal end side of the optical fiber strand can be easily fixed by the strand pressing portion. Moreover, the manufacturing cost of a strand holder can be reduced by integral molding.

また、本発明に係る光ファイバの接続方法は、上述の素線ホルダを用いた光ファイバの接続方法であって、光ファイバ素線の基端側を傾斜載置部に押し付けつつ長手方向に沿って素線把持部に把持させる工程と、光ファイバ素線の先端側を溝部に載置させる工程と、素線押さえ部によって光ファイバ素線の先端側を溝部に押さえ付ける工程とを備えたことを特徴としている。   The optical fiber connection method according to the present invention is an optical fiber connection method using the above-mentioned strand holder, and is along the longitudinal direction while pressing the proximal end side of the optical fiber strand against the inclined mounting portion. And a step of placing the tip end side of the optical fiber strand in the groove portion and a step of pressing the tip end side of the optical fiber strand to the groove portion by the strand pressing portion. It is characterized by.

この光ファイバの接続方法では、傾斜載置部に光ファイバ素線の基端側を押し付けることにより、光ファイバ素線の応力を利用して、容易に光ファイバ素線の先端側を素線載置部の溝部に載置することが可能となっている。また、素線押さえ部によって光ファイバ素線の先端側を溝部に固定できるので、端末処理を施した後、光ファイバをメカニカルスプライス内の短尺光ファイバに突き合わせる際に、素線押さえ部を光ファイバの撓みの支点とすることができる。これにより、光コネクタ内での光ファイバの撓み量を管理することが可能となり、光コネクタと光ファイバとの良好な接続を実現できる。   In this optical fiber connection method, by pressing the proximal end side of the optical fiber strand against the inclined mounting portion, the distal end side of the optical fiber strand can be easily placed on the strand using the stress of the optical fiber strand. It can be placed in the groove portion of the placement portion. In addition, since the tip end side of the optical fiber can be fixed to the groove by the wire pressing part, the optical fiber holding part can be optically connected to the short optical fiber in the mechanical splice after the end treatment. It can be a fulcrum for the deflection of the fiber. Thereby, it becomes possible to manage the amount of bending of the optical fiber in the optical connector, and a good connection between the optical connector and the optical fiber can be realized.

以上説明したように、本発明に係る素線ホルダ及び光ファイバの接続方法によれば、光コネクタと光ファイバとの良好な接続を実現できる。   As described above, according to the strand holder and the optical fiber connection method of the present invention, it is possible to realize a good connection between the optical connector and the optical fiber.

The inclined mounting portion 5 is formed so as to be inclined toward the strand holding portion 3 side in the closed state with respect to the longitudinal direction of the groove portions 6 and 6, and the base end of the optical fiber strand along the inclination The side is placed diagonally.

続いて、上述した構成を有する素線ホルダを用いて光ファイバを光コネクタに接続する接続手順について説明する。   Then, the connection procedure which connects an optical fiber to an optical connector using the strand holder which has the structure mentioned above is demonstrated.

まず、図４に示すように、光ファイバ素線１４の基端側を傾斜載置部５に軽く押し付けることにより、光ファイバ素線１４の応力を利用しながら、溝部１２側から素線挟持部４に光ファイバ素線１４を沿わせる。そして、光ファイバ素線１４の先端側を素線載置部２の各溝部６，６に載置する。次に、図５に示すように、素線押さえ部３を閉じ、載置面Ｐと押さえ面Ｑとによって光ファイバ素線１４の先端部分を挟み込むようにして、光ファイバ素線１４の先端側を溝部６に押さえ付ける。これにより、光ファイバ素線１４を素線ホルダ１に固定する作業が完了する。   First, as shown in FIG. 4, the base end side of the optical fiber 14 is lightly pressed against the inclined mounting portion 5, thereby using the stress of the optical fiber 14 and using the strand 12 from the groove 12 side. 4 is aligned with the optical fiber 14. Then, the tip end side of the optical fiber 14 is placed in each of the grooves 6 and 6 of the strand placing part 2. Next, as shown in FIG. 5, the strand holding portion 3 is closed, and the tip end portion of the optical fiber strand 14 is sandwiched between the placement surface P and the holding surface Q so that the tip end side of the optical fiber strand 14 is located. Is pressed into the groove 6. Thereby, the operation | work which fixes the optical fiber strand 14 to the strand holder 1 is completed.

さらに、光ファイバ素線１４を固定した素線ホルダ１を、ホルダ筐体１５に装着する。このホルダ筐体１５は、図６に示すように、光ファイバ素線１４に端末処理を施す際に用いる専用工具であり、素線ホルダ１が嵌め込まれて装着されるホルダ装着部１６が形成された略直方体形状の本体部１７と、この本体部１７の側面側にヒンジ１０を介して開閉自在に設けられた蓋部１８とを有している。   Furthermore, the strand holder 1 to which the optical fiber strand 14 is fixed is attached to the holder housing 15. As shown in FIG. 6, the holder housing 15 is a dedicated tool used when terminal processing is performed on the optical fiber 14, and a holder mounting portion 16 to which the strand holder 1 is fitted and mounted is formed. The main body 17 has a substantially rectangular parallelepiped shape, and a lid 18 is provided on the side of the main body 17 via a hinge 10 so as to be opened and closed.

このホルダ装着部１６において、素線挟持部４の開閉挟持部１１に対応する位置には、例えば樹脂製の挟持片１９が設けられている。このため、ホルダ装着部１６に素線ホルダ１を装着する際、挟持片１９に開閉挟持部１１が嵌め込まれることにより、図７に示すように、開閉挟持部１１が閉状態となり、光ファイバ素線１４の基端側がしっかりと保持される。そして、図８に示すように、蓋部１８を閉じて素線ホルダ１を固定した後、ホルダ装着部１６の先端から突出する光ファイバ素線１４の先端部分の被覆を除去し、露出する光ファイバ２０を所定の長さにカットする。これにより、端末処理が完了する。   In the holder mounting portion 16, for example, a resin-made clamping piece 19 is provided at a position corresponding to the open / close clamping portion 11 of the wire clamping portion 4. For this reason, when the strand holder 1 is mounted on the holder mounting portion 16, the opening / closing clamping portion 11 is fitted into the clamping piece 19, so that the opening / closing clamping portion 11 is closed as shown in FIG. The proximal end side of the line 14 is firmly held. Then, as shown in FIG. 8, after the lid 18 is closed and the strand holder 1 is fixed, the coating of the tip portion of the optical fiber 14 protruding from the tip of the holder mounting portion 16 is removed, and the exposed light The fiber 20 is cut to a predetermined length. Thereby, terminal processing is completed.

端末処理が終了した後、素線ホルダ１をホルダ筐体１５から取り外し、光ファイバ接続用治具２１を用いて、光ファイバ２０を光コネクタ２２に接続する。この光コネクタ２２は、図９及び図１０に示すように、メカニカルスプライス２３を内蔵する光コネクタであり、メカニカルスプライス２３の先端部分には、短尺光ファイバ２４が挿入されたフェルール２５が保持されている。   After the terminal processing is completed, the wire holder 1 is removed from the holder housing 15, and the optical fiber 20 is connected to the optical connector 22 using the optical fiber connecting jig 21. As shown in FIGS. 9 and 10, this optical connector 22 is an optical connector having a built-in mechanical splice 23. A ferrule 25 into which a short optical fiber 24 is inserted is held at the tip of the mechanical splice 23. Yes.

また、光ファイバ接続用治具２１は、同図に示すように、光コネクタ２２が載置されるコネクタ載置部２６、及びコネクタ載置部２６に向けて素線ホルダ１を案内するファイバガイド部２７が設けられたベース２８と、ベース２８の下側に設けられた回動アーム２９とを有している。   Further, as shown in the figure, the optical fiber connecting jig 21 includes a connector mounting portion 26 on which the optical connector 22 is mounted, and a fiber guide for guiding the strand holder 1 toward the connector mounting portion 26. A base 28 provided with a portion 27 and a rotating arm 29 provided below the base 28 are provided.

ベース２８上において、コネクタ載置部２６とファイバガイド部２７との間には、光ファイバ２０をメカニカルスプライス２３のファイバ挿入空間Ｓに対して位置決めするための断面Ｕ字状の位置決め用ガイド部３２が設けられている。さらに、位置決め用ガイド部３２を挟むように、素線ホルダ１の突起部９に対応する一対の引掛部３０，３０が設けられている。   On the base 28, between the connector mounting portion 26 and the fiber guide portion 27, a positioning guide portion 32 having a U-shaped cross section for positioning the optical fiber 20 with respect to the fiber insertion space S of the mechanical splice 23. Is provided. Further, a pair of hooking portions 30 and 30 corresponding to the protruding portions 9 of the strand holder 1 are provided so as to sandwich the positioning guide portion 32.

一方、回動アーム２９の先端側には、前後一対の楔３１が設けられている。この楔３１は、回動アーム２９の先端側が押下されるとコネクタ載置部２６に進出し、回動アーム２９の後端側が押下されるとコネクタ載置部２６から退避する。図９及び図１０においては、回動アーム２９の先端側が押下されており、メカニカルスプライス２３に設けられた楔挿入口２３ａに楔３１が挿入されて、ファイバ挿入空間Ｓが開状態となっている。   On the other hand, a pair of front and rear wedges 31 are provided on the distal end side of the rotating arm 29. The wedge 31 advances to the connector mounting portion 26 when the tip end side of the rotating arm 29 is pressed down, and retracts from the connector mounting portion 26 when the rear end side of the rotating arm 29 is pressed down. 9 and 10, the distal end side of the rotating arm 29 is pushed down, the wedge 31 is inserted into the wedge insertion port 23a provided in the mechanical splice 23, and the fiber insertion space S is in the open state. .

このようにセットされた光ファイバ接続用治具２１のファイバガイド部２７の端に、図１１に示すように、まず素線ホルダ１を載置する。次に、素線ホルダ１をファイバガイド部２７に沿って光コネクタ２２側にスライドさせ、位置決め用ガイド部３２によって光ファイバ２０を大まかに位置決めしつつ、図１２及び図１３に示すように、メカニカルスプライス２３のファイバ挿入空間Ｓ内に光ファイバ２０の先端を挿入する。   As shown in FIG. 11, the strand holder 1 is first placed on the end of the fiber guide portion 27 of the optical fiber connecting jig 21 set in this way. Next, the strand holder 1 is slid along the fiber guide portion 27 toward the optical connector 22, and the optical fiber 20 is roughly positioned by the positioning guide portion 32, as shown in FIGS. 12 and 13. The tip of the optical fiber 20 is inserted into the fiber insertion space S of the splice 23.

このとき、素線ホルダ１の光コネクタ２２側へのスライド量は、素線載置部２の前面側が位置決め用ガイド部３２に当接する位置で規制される。この位置において、光ファイバ２０の先端は、メカニカルスプライス２３内の短尺光ファイバ２４の後端に突き合わされ、また、引掛部３０と突起部９との協働によって、素線ホルダ１と光コネクタ２２との仮固定がなされる。   At this time, the sliding amount of the strand holder 1 toward the optical connector 22 is regulated at a position where the front side of the strand placement portion 2 contacts the positioning guide portion 32. At this position, the tip of the optical fiber 20 is abutted against the rear end of the short optical fiber 24 in the mechanical splice 23, and the wire holder 1 and the optical connector 22 are cooperated by the hook portion 30 and the projection portion 9. Is temporarily fixed.

最後に、光ファイバ接続用治具２１を保持しながら回動アーム２９の後端側を押下すると、楔３１がメカニカルスプライス２３の楔挿入口２３ａから抜脱し、ファイバ挿入空間Ｓが閉状態となる。これにより、光ファイバ２０と短尺光ファイバ２４との突き合わせ部分が固定される。そして、光ファイバ接続用治具２１を光コネクタ２２から取り外し、素線ホルダ１を光ファイバ素線１４から取り外すと、図１４に示すように、光コネクタ２２への光ファイバ２０の接続が完了する。   Finally, when the rear end side of the rotating arm 29 is pressed while holding the optical fiber connecting jig 21, the wedge 31 is pulled out from the wedge insertion port 23a of the mechanical splice 23, and the fiber insertion space S is closed. . Thereby, the butt | matching part of the optical fiber 20 and the short optical fiber 24 is fixed. When the optical fiber connecting jig 21 is removed from the optical connector 22 and the element holder 1 is removed from the optical fiber element 14, the connection of the optical fiber 20 to the optical connector 22 is completed as shown in FIG. .

以上説明したように、素線ホルダ１では、傾斜載置部５に光ファイバ素線１４の基端側を押し付けることにより、光ファイバ素線１４の応力を利用して、容易に光ファイバ素線１４の先端側を素線載置部２の溝部６，６に載置することが可能となっている。また、素線ホルダ１では、素線押さえ部３及び素線挟持部４によって光ファイバ素線１４の先端側を溝部６，６にしっかりと固定できる。   As described above, in the strand holder 1, the base end side of the optical fiber 14 is pressed against the inclined mounting portion 5, thereby easily utilizing the stress of the optical fiber 14. The tip end side of 14 can be placed in the groove portions 6 and 6 of the strand placement portion 2. Further, in the strand holder 1, the tip end side of the optical fiber strand 14 can be firmly fixed to the groove portions 6 and 6 by the strand pressing portion 3 and the strand clamping portion 4.

また、素線ホルダ１では、端末処理を施した後、光ファイバ２０をメカニカルスプライス２３内の短尺光ファイバ２４に突き合わせる際に、素線押さえ部３を光ファイバ２０の撓みの支点とすることができる。これに加え、素線載置部２の前面側が位置決め用ガイド部３２に当接する位置で、素線ホルダ１の光コネクタ２２側へのスライド量を規制できるので、光ファイバ２０がファイバ挿入空間Ｓに挿入される量が調整され、光コネクタ２２内での光ファイバ２０の撓み量を管理することが可能となる。これにより、光ファイバ２０の端面に大きな荷重がかかったまま接続がなされるようなことが抑制され、光コネクタ２２と光ファイバ２０との良好な接続を実現できる。   Further, in the strand holder 1, after the end treatment is performed, when the optical fiber 20 is butted against the short optical fiber 24 in the mechanical splice 23, the strand pressing portion 3 is used as a fulcrum of bending of the optical fiber 20. Can do. In addition to this, the amount of sliding of the strand holder 1 toward the optical connector 22 can be regulated at the position where the front surface side of the strand placement section 2 abuts against the positioning guide portion 32, so that the optical fiber 20 is in the fiber insertion space S. The amount inserted into the optical connector 22 is adjusted, and the amount of bending of the optical fiber 20 in the optical connector 22 can be managed. Thereby, it is suppressed that a connection is made while a large load is applied to the end face of the optical fiber 20, and a good connection between the optical connector 22 and the optical fiber 20 can be realized.

また、素線ホルダ１の素線載置部２、素線押さえ部３、傾斜載置部５、及び素線挟持部４は、タック性を有する材料によって一体成型されている。そのため、光ファイバ素線１４を素線載置部２に載置し、素線押さえ部３を閉じる際に、素線押さえ部３が素線載置部２に仮止めされるので、素線押さえ部３による光ファイバ素線１４の先端側の固定を容易に行うことができる。また、このような一体成型は、素線ホルダ１の製造コストの低減を実現する。   Moreover, the strand mounting part 2, the strand holding | suppressing part 3, the inclination mounting part 5, and the strand clamping part 4 of the strand holder 1 are integrally molded by the material which has tack property. Therefore, when the optical fiber strand 14 is placed on the strand placement unit 2 and the strand holding unit 3 is closed, the strand holding unit 3 is temporarily fixed to the strand placement unit 2. The tip end side of the optical fiber 14 can be easily fixed by the pressing portion 3. Moreover, such integral molding realizes a reduction in manufacturing cost of the wire holder 1.

本発明は、上記実施形態に限られるものではない。例えば、外径の異なる光ファイバ素線１４に対応させるため、溝部６，６及び素線挟持部４の径を適宜変更してもよい。また、上記実施形態では、タック性を有する材料で素線ホルダ１全体を一体成型しているが、素線押さえ部３を素線載置部２に仮止めするという観点から見れば、図１５に示すように、素線載置部２の載置面Ｐに強いタック性を有する材料４０（例えば粘着テープ）を貼付してもよい。   The present invention is not limited to the above embodiment. For example, in order to correspond to the optical fiber strands 14 having different outer diameters, the diameters of the groove portions 6 and 6 and the strand clamping portion 4 may be appropriately changed. Moreover, in the said embodiment, although the strand holder 1 whole is integrally molded with the material which has tack property, if it sees from a viewpoint of temporarily fixing the strand holding | suppressing part 3 to the strand mounting part 2, FIG. As shown in FIG. 4, a material 40 (for example, an adhesive tape) having strong tackiness may be attached to the placement surface P of the strand placement unit 2.

また、例えば、図１６に示すように、素線押さえ部３の押さえ面Ｑの略中央に、素線ホルダ１の長手方向に沿う段部４１を設けてもよい。この場合、素線載置部２の載置面Ｐに載置された光ファイバ素線１４の先端側をより確実に保持することが可能となる。   Further, for example, as shown in FIG. 16, a stepped portion 41 along the longitudinal direction of the strand holder 1 may be provided in the approximate center of the pressing surface Q of the strand pressing portion 3. In this case, the tip end side of the optical fiber 14 placed on the placement surface P of the strand placement part 2 can be more reliably held.
