【考案の詳細な説明】
本考案は、光フアイバー同士を着脱可能に接続
する装置である光コネクターの提案に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an optical connector, which is a device for removably connecting optical fibers.
さて、光コネクターの構成上基本的に要求され

そして、この要求に応えるための最も重要な要素
は、光フアイバーのコアの端面処理と同じく端面
の突き合わせに係る高い精度である。 Now, what is fundamentally required in the configuration of an optical connector is to completely eliminate connection loss.
The most important element to meet this demand is high precision in the butting of the end faces, as in the end face treatment of the core of the optical fiber.
このため、光コネクターの製造には高度な製造
技術（製造用機械・器具ならびに技術者の熟練
度）を必要とし、したがつて、製造コストも必然
的に押しあげられる結果となつていた。 For this reason, the manufacture of optical connectors requires advanced manufacturing technology (manufacturing machines and equipment as well as the skill level of engineers), which inevitably leads to an increase in manufacturing costs.
このような実情を打開すべく、本考案者らは、
確実な光接続機能を有するもの（接続損失の排除
が図られたもの）にして、簡便かつ安価に製造可
能な光コネクターの開発に務め、その結果、従来

ネクターの完成に至つたものである。 In order to overcome this situation, the inventors of the present invention
We have worked to develop an optical connector that has a reliable optical connection function (one that eliminates connection loss) and can be easily and inexpensively manufactured.As a result, we have developed the following configuration that breaks the conventional concept of optical connectors. This led to the completion of an optical connector.

と成したものである。 In other words, the feature of the optical connector of the present invention is that it uses a gelatinous material with a refractive index that is equivalent to or within an acceptable range of the refractive index of the material used for the core of the optical fiber as a conductor for relaying between optical fibers. This eliminates the need for special (precision) end face treatment of the core of the optical fiber, and eliminates the need for precise butting work of the core end faces.
上述のゲル化状物質になる中継用伝導体はたと
えば次のようにして製造する。 The above-mentioned relay conductor which becomes a gelatinous substance is manufactured, for example, as follows.
軟質シリコーンゲル材料たとえば東レシリコー
ンSE1821（商品名）に硬化剤を混合せしめ主剤を
調整する。 A hardening agent is mixed with a soft silicone gel material such as Toray Silicone SE1821 (trade name) to prepare the main agent.
一方、ガラス等でできた反応槽にオイルを満た
し、界面活性剤を少量加え昇温し、スターラーに
よつて撹伴する。 Meanwhile, a reaction tank made of glass or the like is filled with oil, a small amount of surfactant is added, the temperature is raised, and the mixture is stirred with a stirrer.
この中に、上気主剤（シリコーンゲル混合物）
を静かに摘下する。 In this, the upper air main agent (silicone gel mixture)
gently remove it.
このまま撹伴を続け高温を保つと数分〜数十分
で重合反応が終了し、これにより実用新案登録請
求の範囲第２項に記載の個体としての中継用伝導
体が得られる。 If stirring is continued as it is and the high temperature is maintained, the polymerization reaction will be completed in several minutes to several tens of minutes, thereby obtaining the solid relay conductor described in claim 2 of the utility model registration.
一方、上気主剤（シリコーンゲル混合物）を

用新案登録請求の範囲第３項に記載の中継用伝導
体が得られる。 On the other hand, the main agent (silicone gel mixture)
By injecting it into an aluminum pipe having an inner diameter of 150 microns and gelling it in a constant temperature bath, the relay conductor described in claim 3 of the utility model registration can be obtained.
そして、これを必要長さに切断することにより
中継用伝導体とする。 Then, this is cut to a required length to make a relay conductor.
付記するに；
粒子の大きさは、スクーラーの回転速度により
任意のものを得ることができる。 It should be noted that the size of the particles can be adjusted to any desired size depending on the rotational speed of the cooler.
界面活性剤は、分散された粒子が再結合し大き
な粒子となることを防止する。 Surfactants prevent dispersed particles from recombining into larger particles.
同活性剤は陽イオン系より非イオン系が望まし
い。 The active agent is preferably nonionic rather than cationic.
上記はクリーンルームで行うことを最上条件と
し、反応槽の内側はフツ素樹脂にて加工されてい

反応槽内のオイルは、有機、無機の不純物粒子
およびシリコーンゲルの所謂インヒビターになる
硫黄、塩素などを含まないものがよい。 The oil in the reaction tank is preferably one that does not contain organic or inorganic impurity particles or sulfur, chlorine, etc., which are so-called inhibitors of silicone gel.

１ 光屈折率……1.406（一般的な光フアイバーの
屈折率と同等である）
