ある。 In FIG. 1 and FIG. 2, 1 is an OF cable. Reference numeral 2 denotes a fitting for oil supply, which is compressed and connected to the cable conductor 11 and sealed to the cable sheath 12 with lead metal fittings. A locking groove 21 (which may be a threaded groove) is provided on the outer periphery of this oil supply joint fitting 2. 22 is a connector provided on the joint fitting. 3 is a pulling eye fitting, and arms 30a, 3 are attached to each divided piece of the two-split annular fittings 3a, 3b.
0b is attached, and a locking groove 31 is provided on the inner periphery of the two-part annular metal fitting. 32, 32
are bolts and nuts for fastening the two-split annular fitting, and by this fastening, the two-split annular fitting is locked to the outer periphery of the joint fitting. 300a, 30
0b is a ring provided at the tip of each arm 30a, 30b, and a pulling wire 4 is tightly tied to these rings. Therefore, both arms 30
a and 30b can be separated as the wire 4 is attached or detached.
