本発明は光フアイバ接続部の補強方法を改良したものに
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved method for reinforcing optical fiber connections.
既知の通り、融着接続法を介して接続された光ファイバ
の接続部は第１図のようになっている。As is known, the spliced portion of optical fibers spliced via the fusion splicing method is as shown in FIG.
第１図において、ＩＡ、ＩＢは対をなす被覆光ファイバ
、２Ａ、２Ｂはその被覆部、３Ａ。In FIG. 1, IA and IB are a pair of coated optical fibers, 2A and 2B are their coated portions, and 3A.
３Ｂは被覆光ファイバＩＡ、ＩＢの先端側に形成された
皮剥ぎによる被覆除去部であり、これら被覆除去部３Ａ
、３Ｂはその先端面が互いに突き合わされ、放電加熱、
レーザ加熱などによシ融着接続されている。3B is a coating removal section formed on the tip side of the coated optical fibers IA and IB by stripping, and these coating removal sections 3A
, 3B have their tip surfaces butted against each other and are heated by discharge,
Fusion spliced by laser heating, etc.
ところで、上記における被覆除去部３Ａ、３Ｂは、被覆
が除去されていることにより強度が低下し、表面傷も負
いやすくなっているので、融着接続後において適当な補
強部材により補強される。By the way, the strength of the above-mentioned cover-removed parts 3A and 3B is reduced due to the removal of the cover, and the surfaces are easily damaged, so they are reinforced with an appropriate reinforcing member after fusion splicing.
その補強手段としては、蓋合わせ式とした補強部材のＶ
溝内に光フアイバ接続部を嵌めこみ、接着剤を充填して
当該光フアイバ接続部を補強部材内に固着するのが一般
である。As a reinforcing means, V
Generally, the optical fiber connection part is fitted into the groove and filled with an adhesive to secure the optical fiber connection part within the reinforcing member.
また、この際の接着剤としては、シリコーン系の一液型
ＲＴＶゴムがよく用いられ、この接着剤は室温において
空気中の水分と反応し、硬化する。Further, as the adhesive in this case, silicone-based one-component RTV rubber is often used, and this adhesive reacts with moisture in the air and hardens at room temperature.
ところが上記のようにして光フアイバ接続部を補強する
とき、補強部材は透湿するものの、その内部に充填され
た接着剤は外気とはソ完全に遮断された状態となるので
、完全硬化するまでに長時間を要し、例えば冬期などの
低温条件下では接着剤の硬化に５時間以上も要している
。However, when reinforcing the optical fiber connection as described above, although the reinforcing member is moisture permeable, the adhesive filled inside is completely cut off from the outside air, so it will not work until it is completely cured. For example, under low temperature conditions such as in winter, it takes more than 5 hours for the adhesive to harden.
殊に低温条件下で接着剤が硬化するとき、初期段階では
気泡の発生がないが、その後の硬化過程において伝送ロ
ス増、破断事故の原因となる気泡が発生する。In particular, when the adhesive is cured under low temperature conditions, no bubbles are generated in the initial stage, but bubbles are generated in the subsequent curing process that can increase transmission loss and cause breakage accidents.
これは、接着剤の硬化に必要な水分の絶対量が不足する
ためその硬化が著しく遅れ、接着剤の収縮も生じ、その
結果光フアイバ表面を介して極少の空気をとりこんでし
まい、気泡が発生すると推定できる。This is because the absolute amount of moisture necessary for the adhesive to harden is insufficient, resulting in a significant delay in curing and shrinkage of the adhesive.As a result, a very small amount of air is taken in through the optical fiber surface, creating air bubbles. Then it can be estimated.
また、接着剤が硬化するまでに長時間を要し、この間に
ヒートサイクルなどを受けたシすると、補強部材内で光
フアイバ端部の突き出し現象が生じ、光フアイバ接続部
は接着剤中にて８字ベンドを起す。In addition, it takes a long time for the adhesive to harden, and if it is subjected to a heat cycle etc. during this time, the end of the optical fiber will protrude inside the reinforcing member, and the optical fiber connection will become stuck in the adhesive. Make a figure 8 bend.
これＫよっても光フアイバ接続部の伝送ロス増が大きく
なり、最悪の場合には破断事故も発生する。This K also increases the transmission loss at the optical fiber connection, and in the worst case, a breakage accident may occur.
本発明における特定発明の目的は、この種の補強方法に
おいて補強部材に水分を含ませておくことによシ、接着
剤硬化時間の短縮と気泡発生防止とをはかることにある

なうことにある。The specified invention provides a method for reinforcing an optical fiber connection part fitted into a reinforcing member by fixing it with an adhesive filled in the reinforcing member. 1. The purpose is to fit the optical fiber connection part into the reinforcing member and fill it with adhesive.
本発明方法における第２発明の目的は、上記特定発明と
同じく接着剤硬化時間の短縮と気泡発生防止とをはかり
、さらに補強時の作業湯度、作業速度とともに補強処理
効果をよシ一層高めることにある。The purpose of the second invention in the method of the present invention is to shorten the adhesive curing time and prevent the generation of bubbles, as in the above-mentioned specific invention, and to further enhance the reinforcing treatment effect in terms of the working temperature and working speed during reinforcing. It is in.
第２発明では、補強部材内に嵌めこまれた光フアイバ接
続部をその補強部材内に充填された接着剤により固着し

封包装しておき、その後、包装材内から補強部材を取り
出し、該補強部材内への光フアイバ接続部の嵌めこみ、
ならびに接着剤充填を行なうことを特徴としている。In the second invention, in the method of reinforcing the optical fiber connection part by fixing the optical fiber connection part fitted in the reinforcing member with an adhesive filled in the reinforcing member, the reinforcing member is impregnated with water. Then, the reinforcing member is taken out from inside the packaging material, and the optical fiber connection part is fitted into the reinforcing member.

It is made of FRP, etc.
前述した特定発明を具体的に実施するとき、あらかじめ
補強部材６を、すなわち基板６と蓋板７とを水中に約２
時同根度浸漬しておく。When carrying out the specific invention described above, the reinforcing member 6, that is, the substrate 6 and the cover plate 7 are immersed in water for about 2 minutes.
Soak the roots at the same time.
当該浸漬により基板６、蓋体７には飽和するまで水分を

用される。Thereafter, the adhesive 16 is filled in the groove 9 of the substrate 6, the coating removal parts 3A, 3B'i connected to the groove 9 are fitted, and the coating part 2A is inserted into the groove 10A, 10B. Operations such as inserting 2B are performed in any order,
At this time, the methods shown in FIGS. 2 and 3 mainly employ a method of applying the adhesive 16 to a bamboo skewer and filling it into the groove 9, while the methods shown in FIGS. 4 and 5 use a syringe. A method of filling the adhesive 161 into the groove 9 through a syringe (syringe) is mainly employed.
上記のようにして光フアイバ接続部の嵌めこみ、接着剤
充填を終えた補強部材５は、第３図、第５図に例示する
ごとく、その基板６と蓋体７とが閉じ合わされ、当該閉
合状態がクランプ１６により保持される。After the reinforcing member 5 has been fitted with the optical fiber connection portion and filled with adhesive as described above, its substrate 6 and lid body 7 are closed together, as illustrated in FIGS. 3 and 5. The state is held by a clamp 16.
以下は時間の経過を待って接着剤１６が硬化することに
より所定の補強が完了する。After that, the adhesive 16 hardens over time, and the desired reinforcement is completed.
こうして光フアイバ接続部を補強するとき、水分を要し
て反応する接着剤１６、例えばシリコーン系の一液型Ｒ
ＴＶゴムは補強部材６中にあって外部とはソ完全に遮断
されており、したがって空気中の水分を取りこんで反応

着剤は早期に硬化を完了する。When reinforcing the optical fiber connection part in this way, an adhesive 16 that requires moisture and reacts, such as silicone-based one-component type R, is used.
The TV rubber is located in the reinforcing member 6 and is completely isolated from the outside, so it is not easy to take in moisture from the air and react with it. Since 7 contains moisture like the front legs, the curing reaction is accelerated by obtaining the moisture, and the adhesive completes curing at an early stage.
その結果、光フアイバ接続部の補強処理が早期に完了す

。At this time, the material of the reinforcing member 6 is a thermoplastic resin with excellent mechanical properties, and the groove of the substrate 6 is filled with the liquid type RTV.
Approximately 0.2 to 0.3 a of adhesive 16 made of rubber was injected.

This means that the adhesive 6 in the vicinity is uncured, and a degree of curing of 100% means that the adhesive 6 is completely cured.
