Title:
CONNECTION ADAPTER FOR OPTICAL FIBER AND ENDOSCOPE DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/162884
Kind Code:
A1
Abstract:
This connection adapter (10) comprises: an adapter housing (11); a split sleeve (12); and a spacer (17) having an interval adjustment portion (17a) disposed in the split sleeve (12) and an angle adjustment portion (17b) passing through a slit of the split sleeve (12), secured to the adapter housing (11). When connectors (20a, 20b) are connected to each of two connector ports, each ferrule (23a, 23b) from the connectors (20a, 20b) fits into the split sleeve (12) and is secured therein with the spacer (17) sandwiched therebetween, and thus single-mode optical fibers (22a, 22b) of the respective connectors (20a, 20b) are optically connected to each other without requiring a contact part. Thereby, the present invention provides a connection adaptor capable of creating stable connection efficiency for optical fibers, and an endoscope device using the connection adaptor.
