この発明は、光フアイバを耐圧容器に水密に貫
通、固定させる装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a device for penetrating and fixing an optical fiber into a pressure container in a watertight manner.
近年、深海の開発技術が盛んに推進されている
が、その中で深海中の電子機器と海上の母船間の
計測制御信号の送受信用線路として、軽量、細径

ている。
In recent years, deep-sea development technology has been actively promoted, and among them, a lightweight, small-diameter line that can transmit and receive measurement and control signals between electronic equipment in the deep sea and a mother ship at sea, and that can handle a large amount of data. Consideration has been given to using optical fibers that can transmit signals over long distances without repeating them.
光フアイバを用いる場合の一つの問題は、深海
中の電送機器（光電変換器）と光フアイバとの接
続構造である。すなわち、光電変換器は耐圧容器
内に収納されるが、その内部は大気圧であるか
ら、耐圧容器の内部と外部の間には、例えば6000
ｍの深海においては約600気圧の圧力差を生じる。
そのため光フアイバ貫通部はこの高水圧に耐える
ものでなければならない。 One problem when using optical fibers is the connection structure between deep-sea power transmission equipment (photoelectric converters) and optical fibers. In other words, the photoelectric converter is housed in a pressure-resistant container, but since the inside is at atmospheric pressure, there is a distance of, for example, 6,000 yen between the inside and outside of the pressure-resistant container.
At a depth of 500 m, a pressure difference of approximately 600 atm occurs.
Therefore, the optical fiber penetration part must be able to withstand this high water pressure.
しかるに、従来の水密型光フアイバ貫通部の構

Conventionally, as described above, when high water pressure is applied, the resin adhesive 3 tends to peel off at the interface of the optical fiber 2, which causes a decrease in watertightness, and also causes the optical fiber 2 to peel off at the end of the penetration part or It may be bent or bent inside, which causes increased optical transmission loss.
