Abstract

An optical connector retaining unit includes: an optical connector retaining member that retains an optical connector of a distal end of an optical fiber in a connection standby state being optically connected to nothing; and a reflecting section that reflects visible light emitted from the distal end of the optical fiber after led into a proximal end of the optical fiber opposite to the distal end thereof provided with the optical connector, at an inclination angle of 45 degrees or less with respect to an optical axis of the emitted visible light, or a scattering section that scatters visible light emitted from the distal end of the optical fiber such that scattered light includes light within the inclination angle of 45 degrees or less with respect to the optical axis of the emitted visible light.

First claim

What is claimed is:

1. An optical connector retaining unit comprising:
an optical connector retaining member that retains an optical connector of a distal end of an optical fiber in a connection standby state being optically connected to nothing;
a reflecting section that reflects visible light emitted from the distal end of the optical fiber after led into a proximal end of the optical fiber opposite to the distal end thereof provided with the optical connector, at an inclination angle of 45 degrees or less with respect to an optical axis of the emitted visible light, or a scattering section that scatters visible light emitted from the distal end of the optical fiber such that scattered light includes light within the inclination angle of 45 degrees or less with respect to the optical axis of the emitted visible light, and
an optical path changing section supporting member comprising the reflecting section or the scattering section,
wherein the optical connector retaining member is rotatable with respect to the optical path changing section supporting member around a central axis in a direction intersecting the optical axis.

2. The optical connector retaining unit according to claim 1 , wherein
a plurality of connector engagement sections with which optical connectors of distal ends of optical fibers are engaged and are arranged on the optical connector retaining member along the central axis.

3. The optical connector retaining unit according to claim 1 , further comprising:
a plurality of optical connector retaining members provided such that central axes of the plurality of optical connector retaining members extend to be parallel to each other at intervals in an upward and downward direction.

4. An optical connector retaining unit comprising:
an optical connector retaining member that retains an optical connector of a distal end of an optical fiber in a connection standby state being optically connected to nothing; and
a reflecting section that reflects visible light emitted from the distal end of the optical fiber after led into a proximal end of the optical fiber opposite to the distal end thereof provided with the optical connector, at an inclination angle of 45 degrees or less with respect to an optical axis of the emitted visible light, or a scattering section that scatters visible light emitted from the distal end of the optical fiber such that scattered light includes light within the inclination angle of 45 degrees or less with respect to the optical axis of the emitted visible light,
wherein the optical connector retaining member is a light transmitting connector retaining member that transmits the visible light emitted from the distal end of the optical fiber and formed with a connector engagement hole with which the optical connector is engaged, and
the reflecting section or the scattering section is provided inside the light transmitting connector retaining member or on the optical axis of a rear surface side of the light transmitting connector retaining member.

5. An optical wiring unit comprising:
an optical connector retaining unit comprising:
an optical connector retaining member that retains an optical connector of a distal end of an optical fiber in a connection standby state being optically connected to nothing; and
a reflecting section that reflects visible light emitted from the distal end of the optical fiber after led into a proximal end of the optical fiber opposite to the distal end thereof provided with the optical connector, at an inclination angle of 45 degrees or less with respect to an optical axis of the emitted visible light, or a scattering section that scatters visible light emitted from the distal end of the optical fiber such that scattered light includes light within the inclination angle of 45 degrees or less with respect to the optical axis of the emitted visible light; and

an adapter array section to which an optical connector of a distal end of an optical fiber not retained in the optical connector retaining unit is connected.
