【発明の詳細な説明】 ［産業上の利用分野］ この発明は、海底用光フアイバの接続、海底用中継器内
の接続など、高強度の持続を必要とする部分に使用する
光フアイバの融着接続装置に関するもので、特にＶ溝と
電極を含む部分に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to the fusion of optical fibers for use in parts requiring high-strength continuity, such as submarine optical fiber connections and submarine repeater connections. The present invention relates to a connecting / disconnecting device, and particularly to a portion including a V groove and an electrode.
［従来の技術］ 第４図は、通常の融着接続装置を模型的に示したもので
ある。[Prior Art] FIG. 4 schematically shows a typical fusion splicing device.
10は光フアイバ心線の全体、12は光フアイバ（ガラス部
分）、14は被覆部分。10 is the entire optical fiber core, 12 is the optical fiber (glass part), and 14 is the coated part.
Ｖ溝16に光フアイバ12を入れ、クランプ18で押える。ま
たブロック20上に被覆部分14を支持し、クランプ22で押
えて固定する。Insert the optical fiber 12 into the V groove 16 and press it with the clamp 18. Further, the covering portion 14 is supported on the block 20, and is clamped and fixed by the clamp 22.
光フアイバのx,y方向の調心は、Ｖ溝16を上下、左右に
微動させて行う。また光フアイバのｚ方向の調整を行う
には、ブロック20を前後に移動させる。すると、被覆部
分14はクランプ22により強力に押えられているので、ブ
ロック20とともに移動し、光フアイバ12はＶ溝16の中を
滑って移動する（Ｖ溝16はｚ方向には移動しない）。The optical fiber is aligned in the x and y directions by finely moving the V groove 16 vertically and horizontally. To adjust the optical fiber in the z direction, the block 20 is moved back and forth. Then, since the covering portion 14 is strongly pressed by the clamp 22, it moves together with the block 20, and the optical fiber 12 slides in the V groove 16 (the V groove 16 does not move in the z direction).
24は融着用の電極である。24 is an electrode for fusing.
［発明が解決しようとする問題点］ ガラスの光フアイバ12がＶ溝16に接触したまま移動する
と、傷がついて、強度の低下を来す。[Problems to be Solved by the Invention] When the optical fiber 12 made of glass moves while being in contact with the V groove 16, the glass fiber is scratched and the strength is lowered.
そこで、第５図のように、Ｖ溝26に被覆部分14を入れて
クランプ27で固定し、光フアイバ12は何物にも接触させ
ない支持の方法をとり、Ｖ溝26をx,y,z方向に微動させ
るという方式が提案されている。Therefore, as shown in FIG. 5, the covering portion 14 is put in the V groove 26 and fixed by the clamp 27, and the optical fiber 12 is supported so that it does not come into contact with anything. A method of slightly moving in the direction has been proposed.
ところが、そのようにした場合、従来のものでは、電極
24の高さが変えられないので、被覆部分14の外径が変っ
た場合、あるいは被覆部分14が変形した場合などの光フ
アイバのセンタの変化に対応できなかった。However, in such a case, in the conventional case, the electrode is
Since the height of 24 cannot be changed, it was not possible to cope with the change in the center of the optical fiber when the outer diameter of the covering portion 14 changed or when the covering portion 14 deformed.
そのため、接続強度、接続損失の特性が充分でなかっ
た。Therefore, the characteristics of connection strength and connection loss were not sufficient.
［問題点を解決するための手段］ この発明は、第１図、第２図のように、Ｖ溝26の上を覆
うようにして設けた風防30の下面に、融着用の電極24を
とりつけて、風防30とともに上下運動させることによ
り、その位置を上下に調節可能とし、これにより、上記
の問題の解決を図ったものである。[Means for Solving the Problems] As shown in FIGS. 1 and 2, the present invention mounts the electrode 24 for fusion bonding on the lower surface of the windshield 30 provided so as to cover the V groove 26. By moving the windshield 30 up and down, the position of the windshield 30 can be adjusted up and down, thereby solving the above problem.
［実施例］ 第１図において、28は本体フレーム。[Embodiment] In FIG. 1, 28 is a body frame.
30は風防で、Ｖ溝26付近を覆うように設ける。そして、
その一端を本体フレーム28にヒンジ32して開閉自在とす
る（第２図）。A windshield 30 is provided so as to cover the vicinity of the V groove 26. And
One end of the hinge is hinged to the body frame 28 so that it can be freely opened and closed (Fig. 2).
風防30の下面に電極24を固定する。The electrode 24 is fixed to the lower surface of the windshield 30.
風防30の中央部に顕微鏡34をとりつけ、光フアイバ12と
電極24の先端を観察できるようにする。A microscope 34 is attached to the central part of the windshield 30 so that the tips of the optical fiber 12 and the electrode 24 can be observed.
本体フレーム28にスクリュー36をはめこみ、その頭を、
風防30のつば31に当てる。つば31はヒンジ32の反対側に
設けてある。Insert the screw 36 into the main body frame 28, its head,
Apply to the brim 31 of the windshield 30 The collar 31 is provided on the opposite side of the hinge 32.
モータ38により、スプライン軸40を介してスクリュー36
を回転させると、風防30のつば31が上下に動き、それに
よって電極24の高さが変化する。The motor 36 causes the screw 36 to pass through the spline shaft 40.
When is rotated, the brim 31 of the windshield 30 moves up and down, which changes the height of the electrode 24.
［作 用］ Ｖ溝26を移動させて光フアイバの調心を行った後、顕微
鏡34をまず、光フアイバ12の先端にピント合わせる。[Operation] After the V-groove 26 is moved to align the optical fiber, the microscope 34 is first focused on the tip of the optical fiber 12.
それから上記のように電極24の高さを調整して、その先
端のピントも合うようにする。Then, the height of the electrode 24 is adjusted as described above so that the tip of the electrode 24 is also in focus.
そうすると、光フアイバ12と電極24との高さが合ったこ
とになる。Then, the heights of the optical fiber 12 and the electrode 24 are matched.
［発明の効果］ (1)本発明は光ファイバの被覆部分14をＶ溝26に固定す
る方式であるが、電極24が上下に動くので、被覆部分14
に変形などがある場合でも、光フアイバ12の中心の高さ
に合わせて調整が可能であり、高強度接続に効果的であ
る。[Advantages of the Invention] (1) The present invention is a method of fixing the coated portion 14 of the optical fiber to the V groove 26, but since the electrode 24 moves up and down, the coated portion 14
Even when there is a deformation or the like, it can be adjusted according to the height of the center of the optical fiber 12 and is effective for high strength connection.
(2)従来、電極24は融着機の本体に取り付けられてい
た。そのため、これを上下に移動可能にするには、ある
程度の機構の追加が必要になる。(2) Conventionally, the electrode 24 has been attached to the main body of the fusion machine. Therefore, in order to make it movable up and down, it is necessary to add some mechanism.
しかし本発明の場合は、風防30の下面にとりつけて、風
防30とともに上下運動させるようにするので、上下運動
させること自体について、特別な機構の付加は不要であ
る。However, in the case of the present invention, since it is attached to the lower surface of the windshield 30 and moved up and down together with the windshield 30, it is not necessary to add a special mechanism for the vertical movement itself.
また、風防30の空いた所に付けられるので、風防30が特
別大きくなることもない。In addition, since the windshield 30 can be attached to an empty space, the windshield 30 does not become extra large.
(3)風防30は、通常、片側ヒンジして開閉自在とする。
そこで、上記のように、ヒンジの反対側を、スクリュー
などで上下させるという非常に簡単な機構により、電極
24を上下に調節できるようになる。(3) The windshield 30 is normally hinged on one side so that it can be opened and closed.
Therefore, as described above, the electrode on the opposite side of the hinge can be
24 can be adjusted up and down.
なお、このように風防30が片側ヒンジの場合、厳密に言
えば、電極24は上下に平行移動しないで、第３図（ｂ）
のように、傾斜する。しかし、上下の運動量は微少であ
るので、傾斜の度合もごく軽微であるし、また電極24の
中心線25が、光ファイバ12の突合せ位置を通れば、電極
24は多少傾斜していても、何ら問題はない。When the windshield 30 is a hinge on one side as described above, strictly speaking, the electrode 24 does not move up and down in parallel, and the electrode 24 does not move vertically as shown in FIG.
Tilt, like. However, since the vertical momentum is very small, the degree of inclination is also very small, and if the center line 25 of the electrode 24 passes through the abutting position of the optical fiber 12, the electrode
Even if 24 is slightly inclined, there is no problem.
(4)電極24の上下のために、風防30を動かしても、その
量は微少であるから、風防30本来の役割を果たす上で、
支障はない。(4) Even if the windshield 30 is moved because of the upper and lower sides of the electrode 24, the amount is very small.
There is no hindrance.
(5)光ファイバ心線10をＶ溝26上にセットするときは、
第２図のように、風防30を開く。(5) When setting the optical fiber core wire 10 on the V groove 26,
Open the windshield 30 as shown in FIG.
電極24の先端の間隔は1mm程度の非常に狭いものである
から、光フアイバ12のガラスの部分がそれに接触して傷
つき、強度の低下を起す心配もあった。しかし、風防30
ごと電極24も移動するので、その心配もなくなる。Since the distance between the tips of the electrodes 24 is very narrow, about 1 mm, the glass portion of the optical fiber 12 may come into contact with and be damaged, causing a decrease in strength. However, windshield 30
Since the electrode 24 also moves together, there is no need to worry about that.
