り関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an optical connector, and in particular, when transmitting an optical signal through an optical fiber between atmospheric pressure and vacuum, the environmental condition 1' is used. This relates to an airtight optical connector that blocks and transmits data.
従来、この種の気密構造の光コネクタは、伝送面にガラ
ス等の透明な素子を用いて遮断するか、又は光ファイバ
を接着等で封し込める構造となっていた。Conventionally, this type of airtight optical connector has a structure in which the transmission surface is blocked by using a transparent element such as glass, or the optical fiber is sealed by adhesive or the like.

低く、有人宇宙衛星等における仕様には適さなかった。In the case of the above-mentioned conventional airtight optical connector, if the structure is blocked by glass etc., it is necessary to increase the thickness of the glass etc. in order to obtain a sufficient strength margin for the pressure difference, which causes optical signal scattering and loss. However, if the Hikari Eyepa is fixed with adhesive, the structure must be enlarged in order to obtain the necessary margin of airtightness and pressure resistance, and the quality must be sufficient due to the nature and workability of the adhesive. However, the reliability was low, and it was not suitable for the specifications for manned space satellites.

品質保証もＸ線や気密試験により充分に行える。As explained above, the present invention maintains high airtightness by fixing the optical fiber cable and the connecting connector portion, and the connector and the flange for the number of devices with a hermetic seal, and is also resistant to high pressure differences. This has the effect of increasing the length of the optical fiber and increasing the hermetic area due to the low loss property of the optical fiber. In addition, hermetic seals are stable for long periods of time due to their characteristics, and have excellent airtightness based on their use in vacuum tubes, etc., and quality assurance after processing can be fully performed using X-rays and airtightness tests.
