Method of forming intermediate connection part of optical composite power cable and intermediate connection part of optical composite power cable

摘要

PROBLEM TO BE SOLVED: To connect an optical fiber in a state where a metal tube of the optical fiber is appropriately disconnected electrically in a tube member of the intermediate connection portion to connect the optical composite power cable. I will provide a. An intermediate connection portion 1 of an optical composite power cable has a region R between a reinforcing insulating layer 31 covering a connecting portion between central conductors 11 and 21 and a conductive pipe member 34 arranged outside the reinforcing insulating layer 31. The optical fiber connecting portion 40 for connecting the optical fibers 17 and 27 of the first and second optical composite power cables 10 and 20 arranged in the above is provided, and the optical fiber connecting portion 40 accommodates the optical fiber 17. The first metal tube 18 and the second metal tube 28 accommodating the optical fiber 27, and the tips of the first and second metal tubes 18 and 28 are separated from each other by a predetermined distance. A separating member 41 for holding the tip portions of the tubes 18 and 28 is provided. [Selection diagram] Fig. 1
