[Brief explanation of the drawing]

FIG. 1 is a diagram showing an embodiment of the multi-core optical fiber connector plug of the present invention, and FIG. 2 is a diagram showing the distribution of connection loss values of the multi-core optical fiber connector plug of the present embodiment. Figure 3 shows the amount of movement of the end face of the optical fiber when the tape core wire is compressed and deformed by crimping, and Figure 4a shows the experimental and calculated values of the crimping compression deformation rate and the amount of optical fiber movement. Figure 4b is a diagram showing experimental values of the amount of movement of the optical fiber end face due to crimping compression deformation rate and tension, and Figure 5 is
Figure 6 shows the experimental values of the length of caulking and the amount of movement of the optical fiber end face when tension is taken as a parameter. Figure 6 shows the structure of a single-fiber wire. Figure 7 shows the structure of a tape core. 8 is a perspective view showing the structure of the core component of a conventional multi-core optical connector, and FIG.

Claims (1)

[Claims for Utility Model Registration] 1. A multi-fiber core in which a tape core wire formed by collecting a plurality of optical fibers is attached with a tape core wire whose end face is formed by removing the coating at the tip of the optical fiber, aligning the end faces of the optical fibers, and forming the end face by stress rupture. In the optical fiber connector plug, a plurality of thin holes for positioning optical fibers are arranged in parallel on the end face of the connector plug, the holes having a diameter slightly larger than the outer diameter of the optical fiber;
It has two guide pin holes, and has a tape fiber insertion port at the rear end of the connector plug, and a rectangular cross section that connects the tape fiber insertion port and the optical fiber positioning small diameter hole. a tape fiber insertion hole; a guide portion for guiding each optical fiber to the optical fiber positioning thin hole at a connecting portion between the tape fiber insertion hole and the optical fiber positioning thin hole; and the guide. a transparent lid that is placed above the guide section so that the guide section can be observed; a caulking plate for holding down the tape core wire installed in a part of the middle of the tape core wire insertion hole; and a caulking screw for pressing the said caulking plate. and a caulking stopper for stopping the caulking plate in order to define the caulking compression deformation rate of the optical fiber core. 2. Caulk the caulking stopper so that the compression deformation rate is 15%.
35%, and the length of the caulking plate is 4 mm or more.
