Description

本発明は、光ケーブルの接続技術に係り、特に光ケーブルの光ファイバの融着接続部分を補強するケーブルの融着部補強装置に関する。   The present invention relates to an optical cable connection technique, and more particularly to a cable fusion portion reinforcing device for reinforcing a fusion spliced portion of an optical fiber of an optical cable.

光ケーブルを接続試験する際、測定器側の測定用光ケーブルの光ファイバと被測定用光ケーブルの光ファイバとを接続する方法については種々の方法が提案されている。例えば、熱収縮補強スリーブによる接続、光ケーブル簡易突き合わせ器による仮接続又は融着接続機による仮接続方法等がある。光ケーブルの心線数が多い場合は、熱収縮補強スリーブによる接続方法が適している。一方、光ケーブルの心線数が少ない場合は、光ケーブル簡易突き合わせ器による仮接続又は融着接続機による仮接続が効率的であるとされている。   Various methods have been proposed for connecting the optical fiber of the measurement optical cable on the measuring instrument side and the optical fiber of the optical cable to be measured when performing a connection test on the optical cable. For example, there is a connection by a heat shrinkage reinforcement sleeve, a temporary connection by an optical cable simple butter or a temporary connection method by a fusion splicer. When the number of cores of the optical cable is large, a connection method using a heat shrink reinforcement sleeve is suitable. On the other hand, when the number of cores of the optical cable is small, it is said that temporary connection using an optical cable simple butter or temporary connection using a fusion splicer is efficient.

更に、光ケーブルの光ファイバの融着接続部分を固定する技術が提案されている。例えば、特許文献１の特開２００４−３４７８５０公報「光ケーブルの仮接続補強材及びこれを用いた仮接続方法」に示すように、剛性を有する２枚の外板材と、外板材の内面に取り付けた弾力性を有する内板材と、内板材の各側縁を連結するヒンジと、内板材に光コード、光テープ心線の光ファイバを挟み、かつ光ファイバを強固に押圧し得るように外板材に取り付けた締付け具とを備えた光ケーブルの仮接続補強材が提案されている。
特開２００４−３４７８５０公報 Furthermore, a technique for fixing the fusion spliced portion of the optical fiber of the optical cable has been proposed. For example, as shown in Japanese Patent Application Laid-Open No. 2004-347850, “Temporary Connection Reinforcement Material for Optical Cable and Temporary Connection Method Using the Same”, the two outer plate materials having rigidity and the inner surface of the outer plate material are attached. A flexible inner plate, a hinge that connects each side edge of the inner plate, an optical cord between the inner plate and the optical fiber of the optical tape core, and the outer plate so that the optical fiber can be pressed firmly. There has been proposed a temporary connection reinforcing material for an optical cable provided with an attached fastener.
JP 2004-347850 A

以下、本発明の好ましい実施の形態を図面を参照して説明する。
図１は実施例１の光ケーブルの融着部補強装置を示す斜視図であり、（ａ）はシート材を基板に貼り付ける状態、（ｂ）はシート材を基板に貼り付けた状態である。
本発明の光ケーブルの融着部補強装置は、光ケーブルを接続試験する際、一側例えば測定器側の測定用光ケーブルの光ファイバ１と、他側例えば被測定用光ケーブルの光ファイバ１とを融着接続し、この融着接続部分２を補強する装置である。例えば、光ファイバ１について、その周囲が被覆されているときはこの被覆を剥がしてガラス部分を露出させる。この露出した光ファイバ１の端面同士を接合し、接合部を加熱融着して融着接続部分２とする。図示するように、光心線の融着接続部分２について、多心テープ（４心）について図示しているが、この４心は１例で、例えば１心でも本発明の融着部補強装置を使用できることは勿論である。 Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
1A and 1B are perspective views showing an optical cable fusion part reinforcing device according to a first embodiment, in which FIG. 1A shows a state in which a sheet material is attached to a substrate, and FIG. 1B shows a state in which the sheet material is attached to a substrate.
The optical fiber fusion part reinforcing device of the present invention fuses an optical fiber 1 of a measurement optical cable on one side, for example, a measuring instrument side, and an optical fiber 1 of an optical cable for measurement, for example, when performing a connection test on the optical cable. It is an apparatus which connects and reinforces this fusion splicing part 2. For example, when the periphery of the optical fiber 1 is coated, the coating is removed to expose the glass portion. The exposed end faces of the optical fiber 1 are bonded to each other, and the bonded portion is heated and fused to form a fusion-bonded portion 2. As shown in the figure, a multi-fiber tape (four cores) is shown for the fusion splicing portion 2 of the optical core, but this four core is an example. Of course, can be used.

実施例１の光ケーブルの融着部補強装置は、この融着接続部分２を数本並べて固定するためのアクリル樹脂製等の剛性を有する基板３と、この基板３に、数本並べた光ファイバ１及び融着接続部分２を、この基板３に同時に貼り付けるシート材４とを備えたものである。この基板３とシート材４との間に、光ファイバ１及び融着接続部分２を挟み粘着固定するように構成した。なお、この基板３は、剛性を有する素材から成るものであれば、アクリル樹脂製の素材に限定されない。また、その寸法も限定されないことは勿論である。   An optical cable fusion portion reinforcing apparatus according to the first embodiment includes a substrate 3 having rigidity such as an acrylic resin for fixing a plurality of fusion connection portions 2 side by side, and a plurality of optical fibers arranged on the substrate 3. 1 and the fusion splicing portion 2 are provided with a sheet material 4 for simultaneously affixing to the substrate 3. The optical fiber 1 and the fusion splicing portion 2 are sandwiched between the substrate 3 and the sheet material 4 so as to be adhesively fixed. The substrate 3 is not limited to an acrylic resin material as long as it is made of a material having rigidity. Of course, the dimensions are not limited.

この基板３には、位置決めとなる凹部５を形成している。図１（ａ）に示すように、光ファイバ１及び融着接続部分２を、この凹部５に落とし込むように固定する。この凹部５は、図示するように、融着接続部分２は大きな凹部を形成し、光ファイバ１部分には凹部を形成していない。光ファイバ１部分については、シート材４により基板３へ密着固定するためである。シート材４が、光ファイバ１部分の多少の凹凸を吸収できるからである。なお、光ファイバ１部分にも凹部を形成するときは、位置ずれを防止するために、光ファイバ１の外径よりやや小さい径の凹部を形成することが好ましい。   The substrate 3 has a recess 5 for positioning. As shown in FIG. 1A, the optical fiber 1 and the fusion splicing portion 2 are fixed so as to drop into the recess 5. As shown in the figure, the recess 5 has a large recess in the fusion splicing portion 2 and no recess in the optical fiber 1 portion. This is because the optical fiber 1 portion is closely fixed to the substrate 3 by the sheet material 4. This is because the sheet material 4 can absorb some unevenness of the optical fiber 1 portion. In addition, when forming a recessed part also in the optical fiber 1 part, in order to prevent position shift, it is preferable to form a recessed part with a diameter a little smaller than the outer diameter of the optical fiber 1. FIG.

実施例１のシート材４は、複数本の光ファイバ１及び融着接続部分２を一括して固定するように、基板３の略全面を覆う程度の大きさの１枚の部材である。これにより、基板３上に、光ファイバ１及び融着接続部分２を並べ、図１（ｂ）に示すように、その上に1枚のシート材４を貼り付ければ、複数本の光ファイバ１及び融着接続部分２を、基板３とシート材４とに一括して粘着固定することができる。粘着剤は基板３側又はシート材４側の何れに塗布してもよい。但し、基板３の表面に、光ファイバ１に関する接続情報を記入するときは、シート材４側に粘着剤を塗布することが好ましい。   The sheet material 4 of Example 1 is a single member having a size enough to cover substantially the entire surface of the substrate 3 so that the plurality of optical fibers 1 and the fusion splicing portion 2 are fixed together. Thereby, if the optical fiber 1 and the fusion splicing portion 2 are arranged on the substrate 3 and a single sheet material 4 is adhered thereon as shown in FIG. 1B, a plurality of optical fibers 1 are obtained. In addition, the fusion splicing portion 2 can be adhesively fixed to the substrate 3 and the sheet material 4 together. The adhesive may be applied to either the substrate 3 side or the sheet material 4 side. However, when writing connection information regarding the optical fiber 1 on the surface of the substrate 3, it is preferable to apply an adhesive to the sheet material 4 side.

また、本発明の光ケーブルの融着部補強装置は、光ファイバ１のスリーブがないときに、適度なテンションを付与し、その対断線能力も向上させることができ、光ファイバ１が断線するおそれを回避することができる。そこで、４本又は８本といった１スロット単位で光ファイバ１の仮接続を実施することができる。   In addition, the optical fiber fused portion reinforcing device according to the present invention can impart an appropriate tension when the optical fiber 1 has no sleeve, and can improve the ability to break the optical fiber 1. It can be avoided. Therefore, the optical fiber 1 can be temporarily connected in units of one slot such as four or eight.

図２は柔軟性を有する基板を用いた実施例１の変形例を示し、シート材を基板に貼り付ける状態の斜視図である。
この実施例１の変形例では、基板３自体をスポンジ状の柔軟性を有する素材にした。本発明の光ケーブルの融着部補強装置は、複数本の光ファイバ１及び融着接続部分２を、基板３とシート材４との間に一括して挟み粘着固定する装置である。そこで、基板３は図１に示したように、凹部５を形成した剛性を有する部材に限定されない。例えば、複数本の光ファイバ１及び融着接続部分２を、より緊密に密着固定するために、基板３自体をスポンジ状の柔軟性を有する素材、例えばウレタン樹脂を成型したものを用いることができる。この柔軟性を有する素材の下面には剛性を有する台座６を張り付けたものが好ましい。基板３が柔軟性を有していると、装着作業を的確に行なえないことがあるからである。なお、柔軟性を有する素材であっても、表面即ち光ファイバ１及び融着接続部分２を固定する面が軟らかく、その反対面が固くなるように成型したものであれば、この台座６は不要になる。 FIG. 2 is a perspective view showing a modification of the first embodiment using a flexible substrate, in which a sheet material is attached to the substrate.
In the modification of Example 1, the substrate 3 itself is made of a sponge-like material. The optical cable fusion part reinforcing apparatus of the present invention is an apparatus for sandwiching and fixing a plurality of optical fibers 1 and fusion splicing portions 2 between a substrate 3 and a sheet material 4 together. Therefore, the substrate 3 is not limited to a rigid member having the recess 5 as shown in FIG. For example, in order to more closely fix and fix the plurality of optical fibers 1 and the fusion splicing portion 2, the substrate 3 itself can be made of a sponge-like material, such as a urethane resin molded one. . It is preferable to attach a rigid base 6 to the lower surface of the flexible material. This is because if the substrate 3 has flexibility, the mounting operation may not be performed accurately. In addition, even if it is a material which has flexibility, if the surface, that is, the surface for fixing the optical fiber 1 and the fusion splicing portion 2 is soft and the opposite surface is hardened, this pedestal 6 is unnecessary. become.

図３は複数枚のシート材から成る実施例２の光ケーブルの融着部補強装置を示す斜視図であり、（ａ）はシート材を基板に貼り付ける状態、（ｂ）はシート材を基板に貼り付けた状態である。
実施例２の光ケーブルの融着部補強装置では、複数本の凹部５を形成した１枚の基板３に対してそれぞれに複数枚のシート材４を取り付けた。本発明の融着部補強装置は、複数本の光ファイバ１及び融着接続部分２を、１枚の基板３にシート材４を用いて一括して挟み粘着固定する装置であるが、シート材４は、各光ファイバ１及び融着接続部分２を覆う程度の大きさから成るものを用いることができる。このように構成すれば、複数の光ファイバ１及び融着接続部分２を個々に固定することができる。例えば図３（ｂ）に示すように、４本の光ファイバの中で、１本だけ交換又は装着し直しするときは、該当するもののシート材４のみを剥がして作業することができる。残りの光ファイバ１に触れることなく該当する光ファイバ１のみを取り扱うことができる。 FIGS. 3A and 3B are perspective views showing an optical cable fusion part reinforcing device of Example 2 composed of a plurality of sheet materials, in which FIG. 3A shows a state in which the sheet material is attached to the substrate, and FIG. It is in the pasted state.
In the optical cable fusion part reinforcing apparatus of Example 2, a plurality of sheet materials 4 were attached to a single substrate 3 on which a plurality of recesses 5 were formed. The fusion part reinforcing apparatus of the present invention is an apparatus for sandwiching and fixing a plurality of optical fibers 1 and fusion splicing portions 2 together on a single substrate 3 using a sheet material 4. 4 may be formed of a size that covers each optical fiber 1 and the fusion splicing portion 2. If comprised in this way, the some optical fiber 1 and the fusion splicing part 2 can be fixed individually. For example, as shown in FIG. 3B, when only one of the four optical fibers is replaced or remounted, only the corresponding sheet material 4 can be peeled off. Only the corresponding optical fiber 1 can be handled without touching the remaining optical fibers 1.

図４は柔軟性を有する基板を用いた実施例２の変形例を示す斜視図でり、（ａ）はシート材を基板に貼り付ける状態、（ｂ）はシート材を基板に貼り付けた状態である。
この実施例２の変形例でも、基板３自体をスポンジ状の柔軟性を有する素材を用いることができる。実施例２の構成でも、基板３については、凹部５を形成した剛性を有する素材で成型する必要はない。基板３自体を、例えばウレタン樹脂を成型したものを用いることができる。このように構成すれば、複数本の光ファイバ１及び融着接続部分２をより緊密に密着固定することができる。なお、このときも、装着作業を的確に行なえるように、剛性を有する台座６の上に柔軟性を有する素材を張り付けたもの等が好ましい。 FIG. 4 is a perspective view showing a modified example of Example 2 using a flexible substrate, where (a) shows a state where the sheet material is attached to the substrate, and (b) shows a state where the sheet material is attached to the substrate. It is.
Also in the modified example of the second embodiment, a material having sponge-like flexibility can be used for the substrate 3 itself. Even in the configuration of the second embodiment, it is not necessary to mold the substrate 3 with a material having rigidity in which the concave portions 5 are formed. As the substrate 3 itself, for example, one obtained by molding a urethane resin can be used. If comprised in this way, the multiple optical fiber 1 and the fusion splicing part 2 can be more closely stuck-fixed. In this case, it is preferable to attach a flexible material on the rigid base 6 so that the mounting operation can be performed accurately.

図５は複数枚の基板から成る実施例３の光ケーブルの融着部補強装置を示す正面図であり、（ａ）はシート材を各板部材に貼り付ける状態、（ｂ）はシート材を各板部材に貼り付け、板部材を折り畳む状態、（ｃ）は板部材を折り畳んだ状態である。
実施例３の光ケーブルの融着部補強装置では、基板３（板部材１１）自体をコンパクトに折り畳めるように構成した。この実施例３の融着部補強装置は、１枚の基板に代えて、複数枚の板部材１１から成り、各板部材１１の端縁をヒンジ１２で連結して成る基板３と、基板３の各板部材１１に取り付けた、各光ファイバ１及び融着接続部分２を覆うシート材４とを備えた。各板部材１１に、光ファイバ１及び融着接続部分２との位置決めとなる溝１３を形成した。このように構成した実施例３の融着部補強装置は、光ファイバ１及び融着接続部分２を、各板部材１１と各シート材４とに挟み粘着固定し、更に各板部材１１を折り畳める。このように各板部材１１を折り畳むことにより、コンパクトに収納することができ、それぞれの光ファイバ１を容易に管理することができる。 FIGS. 5A and 5B are front views showing an optical cable fusion part reinforcing device according to Example 3 composed of a plurality of substrates. FIG. 5A shows a state in which a sheet material is attached to each plate member, and FIG. The state which is affixed on a board member and a board member is folded, (c) is the state which folded the board member.
In the optical cable fusion part reinforcing apparatus of Example 3, the substrate 3 (plate member 11) itself was configured to be folded compactly. The fusion part reinforcing device of the third embodiment is composed of a plurality of plate members 11 instead of a single substrate, and a substrate 3 in which the edge of each plate member 11 is connected by a hinge 12; And a sheet material 4 covering each optical fiber 1 and the fusion splicing portion 2 attached to each plate member 11. Each plate member 11 was provided with a groove 13 for positioning the optical fiber 1 and the fusion splicing portion 2. In the fusion part reinforcing apparatus according to the third embodiment configured as described above, the optical fiber 1 and the fusion splicing part 2 are sandwiched and fixed between the plate members 11 and the sheet members 4, and the plate members 11 are further folded. . Thus, by folding each plate member 11, it can accommodate compactly and can manage each optical fiber 1 easily.

この実施例３の融着部補強装置でも、各板部材１１は溝１３を形成した剛性を有する素材に限定されない。各板部材１１自体をスポンジ状の柔軟性を有する素材を用いることができる。この柔軟性を有する素材の板部材１１では、溝１３を必ずしも形成する必要はない。   Also in the fusion part reinforcing apparatus of the third embodiment, each plate member 11 is not limited to a material having rigidity in which grooves 13 are formed. A material having sponge-like flexibility can be used for each plate member 11 itself. In the plate member 11 made of a material having flexibility, the grooves 13 are not necessarily formed.

図６は複数枚の基板から成る実施例４の光ケーブルの融着部補強装置を示す正面図であり、（ａ）はシート材を各板部材に貼り付ける状態、（ｂ）はシート材を各板部材に貼り付け、板部材を折り畳む状態、（ｃ）は板部材を折り畳んだ状態である。
実施例４の光ケーブルの融着部補強装置は、実施例３の基板３（板部材１１）の変形例である。この実施例４の融着部補強装置は、各板部材１１に、光ファイバ１及び融着接続部分２との位置決めとなる溝１３を中心線ＣＬからずらして形成した。このように構成した実施例４の融着部補強装置では、光ファイバ１及び融着接続部分２を、各板部材１１と各シート材４とに挟み粘着固定し、更に各板部材１１を折り畳む際に、光ファイバ１及び融着接続部分２との膨らみ部分が相互に干渉しないので、各板部材１１をコンパクトに折り畳むことができる。 FIGS. 6A and 6B are front views showing a fusion-bonding portion reinforcing device for an optical cable according to Example 4 composed of a plurality of substrates. FIG. 6A shows a state in which a sheet material is attached to each plate member, and FIG. The state which is affixed on a board member and a board member is folded, (c) is the state which folded the board member.
The fused portion reinforcing device for an optical cable according to the fourth embodiment is a modification of the substrate 3 (plate member 11) according to the third embodiment. In the fusion-portion reinforcing device of Example 4, the groove 13 serving as the positioning of the optical fiber 1 and the fusion splicing portion 2 is formed in each plate member 11 so as to be shifted from the center line CL. In the fusion part reinforcing apparatus of Example 4 configured as described above, the optical fiber 1 and the fusion splicing part 2 are sandwiched and fixed between each plate member 11 and each sheet material 4, and each plate member 11 is further folded. At this time, since the bulging portions of the optical fiber 1 and the fusion splicing portion 2 do not interfere with each other, each plate member 11 can be folded in a compact manner.

各板部材１１が柔軟性を有する場合は、溝１３に代えて光ファイバ１を嵌め込むスリット又は切り欠き（図示していない）を形成したものでもよい。このようなスリット又は切り欠きにより光ファイバ１の位置決めを容易に行うことができる。   When each plate member 11 has flexibility, a slit or notch (not shown) for fitting the optical fiber 1 in place of the groove 13 may be formed. The optical fiber 1 can be easily positioned by such slits or notches.

なお、本発明は、光ケーブルの光ファイバ１の融着接続部分２をコンパクトな部材で固定することで、同時に複数本の光ケーブルを補強固定することができ、かつ複数本のケーブルを容易に管理することができれば、上述した発明の実施の形態に限定されず、本発明の要旨を逸脱しない範囲で種々変更できることは勿論である。   In the present invention, by fixing the fusion splicing portion 2 of the optical fiber 1 of the optical cable with a compact member, it is possible to simultaneously reinforce and fix a plurality of optical cables and easily manage the plurality of cables. If possible, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.
