不発BAはパンチファイバの分岐接続方法に係わるもの
である。DETAILED DESCRIPTION OF THE INVENTION The unexploded BA relates to a method for branching and connecting punched fibers.
第1図はパンチファイバの断面図であって、】は単心の
光ファイバであジ、2はそのコア部である。FIG. 1 is a cross-sectional view of a punched fiber, where ] is a single-core optical fiber, and 2 is its core.
単心の光ファイバ1は通常7心を第1図のように配列し

リットがある。このようなバ接続4.コネクタ接続等に
よって行なうことができる。Single-core optical fiber 1 is usually made by arranging seven fibers as shown in Figure 1 and drawing them all at once.
, it has the advantage that the seven fibers can be handled as if they were a single optical fiber. Such a bar connection 4. This can be done by connecting a connector or the like.
第1(2)のように7屯・で構成さnるパンチファイバ
については1回の接続作業で7心の接続が可能であり、

に利点があるとはいうものの最終的に、+、L−っつ、
各端末に光フアイバ全分岐させる場合、適当な手段がな
く、実用化をはばんでいた。For punched fibers consisting of 7 tons as in No. 1 (2), it is possible to connect 7 fibers in one connection operation,
This has the advantage of allowing efficient connections. However, despite these advantages, in the end, +, L-,
If all the optical fibers were to be branched to each terminal, there was no suitable means, which hindered practical application.
本発明は工事現場でも容易に分岐接続できるバッチファ
イバの分岐接続方法を提供するものである。The present invention provides a method for branching and connecting batch fibers that can be easily branched and connected even at construction sites.
以下7心のパンチファイバの分岐接続を例にとり説明す
るが、本発明はバッチファイ〜の心数にかかわりな〈実
施することができる。The following explanation will be given by taking as an example the branch connection of 7-fiber punched fibers, but the present invention can be implemented regardless of the number of fibers in the batch fiber.
第1図に示すようにバッチファイノ月5を構成する各七
・の径d(すなわち1の外径)は通常単ノド線の裸光フ
ァイバ外径d′より一般にがなり 4−fil (形成
さ几ている。この理由はもしd=d’であると、パンチ
ファイバの径りはD二3d=3d’となり、3倍の太さ
になるため、ケーブルの単位断面積当シの光ファイバの
収容効率が低下することならびに曲げを加えたとき、表
面に発生する応力が径が太くなる根太きくなり、信頼性
上好ましくない等である。As shown in FIG. 1, the diameter d (i.e., the outer diameter of 1) of each of the fibers constituting the batch fiber 5 is generally larger than the outer diameter d' of a single-node bare optical fiber. The reason for this is that if d = d', the diameter of the punched fiber will be D23d = 3d', which means it will be three times as thick, so it will be difficult to accommodate the optical fiber per unit cross-sectional area of the cable. The efficiency decreases, and when bending is applied, the stress generated on the surface increases the diameter and thickness, which is unfavorable in terms of reliability.
従って単心の裸ファイバを配列したときには光ファイバ
のコアの位置が太きくず扛てし丑うので、単心の裸フア
イバ側を縮径することが必要である。Therefore, when single bare fibers are arranged, the position of the core of the optical fiber becomes thick and scrapes, so it is necessary to reduce the diameter of the single bare fiber side.
以下第2囚に示す実施例について説明する。The embodiment shown in the second prisoner will be described below.
第2図の3は光フアイバ心線のプラスチック被覆部であ

イバ側同定部13で固定する。次に固定部12.13で
裸ファイバ4を固定した1寸、固定部13ヲ矢印方向に
回転させる。In FIG. 2, numeral 3 is the plastic coating of the optical fiber, and numeral 4 is seven bare fibers. 1. When removing the coating,
The sheathing section 3 is fixed with a fixing section I2 on the core side consisting of a stand 7 and a presser plate 6, the sheathing section 4 is stripped off, and the free end of the exposed bare fiber 4 is fixed using a stand 9 and a presser plate 8. It is fixed with the bare fiber side identification part 13. Next, the bare fiber 4 is fixed by the fixing parts 12 and 13, and the fixing part 13 is rotated in the direction of the arrow.
このようにすると中央部において撚り部5を生じる。次

ッキングを生じ、引き伸ばし量を適切に選ぶことにより
、バッチファイバ15の径りと同一寸法とすることがで
きる。In this way, a twisted portion 5 is created in the central portion. Next, discharge electrode 10. During step II, a discharge circuit (not shown) generates discharge, and the twisted portion 5 is heated and melted and bonded. At this time, one or both of the I wire side fixing section] 2 and the bare fiber side fixing section 13 are moved in a direction in which the distance between them becomes wider. If this is done, necking will occur in the fused portion, and by appropriately selecting the amount of stretching, the diameter can be made to be the same as the diameter of the batch fiber 15.
この場合、放電電極10. Il’i一対として撚り8
5の長平方向に移動させnは、より長い距離にわたって
加熱することになるので、より長い区間、すなわちパン
チファイバの径りと等しい径の部分が得ら几る。In this case, the discharge electrode 10. Il'i twisted as a pair 8
Since the heating is carried out over a longer distance by moving in the longitudinal direction of 5, a longer section, that is, a portion with a diameter equal to the diameter of the punched fiber can be obtained.
以」二の実施例は放電加熱によるものについて述べたが

、撚り部5を軸に回転させてもよい。Although the second embodiment has been described using discharge heating, the heating source may be a gas torch, a CO2 laser, or the like. Furthermore, if the single-core bare fiber has a large diameter and heat is not applied uniformly, the heat source or fixed RII+2.13 may be rotated around the twisted portion 5.
−また本説明においてはd(d’の場合につ遁てのべた
が、d−d′の場合には引き伸ばしは不要である。- Also, in this explanation, we have focused on the case of d(d'), but in the case of d-d', stretching is not necessary.
このようにして、加熱引伸し後、引伸し部の過当な位置
で切断を行う。In this way, after heating and stretching, cutting is performed at the appropriate position of the stretching section.

する工程を第4図で説明する。FIG. 3 shows the state after cutting, and numeral 14 in the figure is the stretched n-leg portion. Cutting is performed using known techniques, e.g.
Methods such as scratching the surface with a knife, bending, applying tensile stress, and cutting with a diamond cutter are used. The process of connecting the batch fiber 15 to the n-L stretching fiber 14 whose outer diameter is reduced to the same diameter as the punch fiber 15 in this manner will be described with reference to FIG.

Since the bare punched fiber 15 and the stretched portion 14 have the same diameter, by fixing them in a groove or the like, it is easy to fully align their axes using their end faces. In other words, it is possible to automatically match the ratio of the outer diameter of the bare fiber 4 of the batch fiber to its core in advance for each year, as well as the axis of the core of each batch fiber. be. In this state, the abutting portions of the two may be adhesively fixed to the V-groove, or they may be fused and spliced to the V-groove in a controlled manner.

バと同じように配列してもJ二い。In the above embodiment, each single bare fiber was twisted and arranged, but it is not necessarily necessary to arrange it by twisting. For example, in the case of a batch fiber made of 7 fibers, as shown in FIG. It is also possible to insert the fibers into the hexagonal holes and arrange them in the same way as the seven single fibers, as shown in the figure.
