Claims

[Claims for Utility Model Registration] 1. In an optical fiber unit of an optical connection adapter provided on a printed wiring board and used for connecting optical paths, a crane-shaped optical fiber and optical fibers connected to both ends of the optical fiber, respectively. and a contact, the optical contact is arranged to be movable within a certain range in the optical axis direction of the optical contact, and optical connection and disconnection are performed by moving the optical contact in the optical axis direction, An optical fiber unit of an optical connection adapter, wherein the optical fiber is in a relaxed state when the optical contacts are at the farthest positions from each other. 2. The optical fiber unit of an optical connection adapter according to claim 1, further comprising a rotation stopper for preventing displacement of the optical contact due to stress in the optical fiber generated when the optical contact is moved. 3. Claim 1, wherein the optical fiber is twisted in advance within a range that does not cause optical problems, in order to disperse stress in the optical fiber as much as possible when moving the optical contact. Or an optical fiber unit of an optical connection adapter according to claim 2.
