OPTICAL FIBER CONNECTION ADAPTER AND ENDOSCOPE APPARATUS

摘要

An optical fiber connection adapter connects connectors, which each include a ferrule that contains a tip of a single-mode optical fiber, and guides light from a laser light source from the interior to the exterior of a casing. The adapter includes a housing, a sleeve configured so that the ferrules are inserted therein and so that the single-mode optical fibers of the connectors are optically connected to each other, and a dust protection ring disposed at a casing side of the sleeve and configured to regulate rotation of the sleeve relative to the housing and to shield an interval between the interior of the casing and the interior of the housing when the connector at the casing side is connected.

1. An optical fiber connection adapter that connects connectors and guides light from a laser light source from an interior to an exterior of a casing, each connector including a ferrule that contains a tip of a single-mode optical fiber, the adapter comprising:
a housing including two opposing connector connecting portions; a sleeve disposed between the two connector connecting portions and configured so that when the connectors are respectively connected to the two connector connecting portions, the ferrule of each of the connectors is inserted into the sleeve, and the single-mode optical fibers of the connectors are optically connected to each other; and a dust protection member disposed at a casing side of the sleeve and configured to regulate rotation of the sleeve relative to the housing and to shield an interval between the interior of the casing and an interior of the housing when the connector at the casing side is connected to the connector connecting portion at the casing side.
