【考案の詳細な説明】
本考案は光フアイバーの壁貫通部の構造に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a wall-penetrating portion of an optical fiber.
以下図面に示す実施例によつて説明する。 The embodiments shown in the drawings will be explained below.
ロツド中心に光信号が通過するコア層を持つガ
ラスロツド（オプチカルロツド）などの光透過性
ロツド２が容器端板（壁）１に保持される光フア
イバーの貫通部の構造において、ロツド２は直径
φ5.0mm以下のたとえばガラスで作られたものであ
るため機械的に十分な強度が得られない欠点があ
つた。 In the structure of an optical fiber penetration part in which a light-transmitting rod 2 such as a glass rod (optical rod) having a core layer in the center of the rod through which an optical signal passes is held in a container end plate (wall) 1, the rod 2 has a diameter Since it was made of glass, for example, with a diameter of less than 5.0 mm, it had the disadvantage that it did not have sufficient mechanical strength.
このためロツド両端の光フアイバーを接続して
光信号回路を構成した場合、外力によりロツド２
が損傷を受ける心配があり、また光フアイバー７
とロツド２との接続も難しいなどの問題があつ
た。 Therefore, when an optical signal circuit is constructed by connecting the optical fibers at both ends of the rod, the rod 2
There is a risk of damage to the optical fiber 7.
There were also problems such as difficulty in connecting with Rod 2.
この考案はこれらの点を改良するための構造を
提供するものである。 This invention provides a structure for improving these points.
即ち図に示す如くロツド２の外径より大きい内
径を有する円筒部３２を有し、片端に容器端板１
に固定出来るような鍔部３１を有し、他端に光コ
ネクタ５を接続できるような接続部３３を有する
保護管３をロツド２の外周に被せ、ロツド２を機
械的に格納するようにしたものである。 That is, as shown in the figure, it has a cylindrical portion 32 having an inner diameter larger than the outer diameter of the rod 2, and has a container end plate 1 at one end.
A protective tube 3 having a flange 31 that can be fixed to the rod and a connecting portion 33 to which an optical connector 5 can be connected at the other end is placed over the outer periphery of the rod 2 to mechanically store the rod 2. It is something.
この保護管３は、たとえば繊維強化プラスチツ
クなどの硬質プラスチツクまたはセラミツクなど
からなり、原子炉格納容器等に使用される気密貫
通部の場合は金属パイプ特にステンレス鋼管など
が適当であり、放射線の強い場所では鉛管も適当
である。４は壁取付ネジである。 The protective tube 3 is made of hard plastic such as fiber-reinforced plastic or ceramic, and in the case of an airtight penetration part used in a nuclear reactor containment vessel, a metal pipe, especially a stainless steel pipe, etc. is suitable. Then, lead pipes are also suitable. 4 is a wall mounting screw.
上記の構造によれば保護管３は容器端板（壁）
１に固定され自立しているので、ロツド２に力が
直接加えられることなく、外力から保護すること
が出来、また光コネクタ５と接続してこれを支え
るので、コネクタ５及び光フアイバーケーブル７
の重量をロツド２に全く加えることがなく重要な
ロツドを安全に保護することが出来る。また、原
子炉格納容器等に使用される場合、ロツドの外周
を金属からなる保護管で囲うと、耐放射線性が向
上する利点がある。 According to the above structure, the protection tube 3 is the container end plate (wall)
Since it is fixed to the rod 1 and stands on its own, it can be protected from external force without applying force directly to the rod 2. Also, since it is connected to the optical connector 5 and supports it, the connector 5 and the optical fiber cable 7
The important rod can be safely protected without adding any weight to the rod 2. Furthermore, when used in a nuclear reactor containment vessel or the like, it is advantageous to surround the outer periphery of the rod with a protective tube made of metal to improve radiation resistance.
なお、壁貫通部に気密性が要求される場合は、
容器端板１と光透過性ロツド２をたとえば金属ス
リーブ６を介して接続してもよく、または、パテ
などのシール材を施してもよい。 In addition, if airtightness is required for wall penetrations,
The container end plate 1 and the light-transmitting rod 2 may be connected, for example, via a metal sleeve 6, or a sealing material such as putty may be applied.
