CAP DEVICE FOR END OF PULLING-UP TUBE FOR MULTIPLE LAYING OPTICAL FIBER CABLE FOR COMMUNICATION

摘要

PROBLEM TO BE SOLVED: To prevent the occurrence of a fault in optical fiber cables by making it possible to lay multiple pieces of the optical fiber cables for communication and preventing a cable protecting tube from moving at the time of leading in the optical fiber cables. SOLUTION: The cap device of the end of a pulling up tube comprises a cylindrical part 4 for insertion of the cable protecting tube 7 a cap 1 for the end of the pulling up tube projectingly provided with a conical cylindrical part 5 for drawing out on a circular cylindrical part 2, a conical cylindrical cap 6 for drawing out the optical fiber cable C2 to be fitted to the top end of the cable protecting tube inserted into the cylindrical part 4 and a pole flank fixture 8 for clamping the cable protecting tube 7 and fixing the same to the pole flank by means of a band 89.
