Description

  The present invention is a movable optical connector used when optical fiber cables laid in a building such as a detached house or a building are connected to each other, and the connection end face of the optical connector is in the longitudinal direction of the optical fiber. The present invention relates to a movable optical connector having an optical connector rotating portion that rotates relative to the optical connector, and an optical fiber cable wiring method for laying an optical fiber cable in a building using the movable optical connector.

  As a conventional technique, when connecting optical fiber cables installed in a building such as a detached house or a building, the F04 type single core installed at the tip of both optical fiber cables via an optical adapter. There is a method of connecting an optical connector such as an SC type optical connector of an optical fiber connector in the longitudinal direction of the optical fiber by PC (Physical Contact).

  The connection method of the optical connector via the optical adapter is not sufficient for constructing a home network by connecting and laying optical fiber cables in a building such as a detached house or building.

  FIG. 5 is a perspective view showing a conventional optical fiber cable wiring method for a home network. A light outlet 11 is provided on a wall in a building such as a detached house or a building. A trunk cable is drawn into the optical outlet 11 by piping, and an optical connector connecting portion 12 is provided on the front surface of the face plate of the optical outlet 11. By inserting and connecting the connection end face of the SC-type optical connector 13 to the optical connector connecting portion 12, the wiring cable connected to the SC-type optical connector 13 and the trunk cable are connected. However, when connecting the main line cable and the wiring cable, the SC-type optical connector 13 has to be greatly projected on the front face of the face plate of the optical outlet 11. Therefore, in the vicinity of the optical outlet 11, there is a high possibility that the aesthetic appearance is impaired and the influence of the external environment is increased, and there are problems in operation and maintenance.

  In addition, when connecting conventional SC optical connectors via optical adapters and laying optical fiber wiring cables in the building, bends at the corners of the entrance and exit corners are permitted at the connection points of the wiring cables. Ensuring a radius of curvature and creating a gap between the wiring cable and the wall, etc., impairs the appearance near the entrance and exit corners and increases the possibility of damage to the wiring cable due to the external environment. Operation and maintenance There was a problem above. Furthermore, due to the difference in the form of the home (building), there are various angles (or directions) at the connection points of the wiring cables, so the conventional SC type optical connector is insufficient.
