PURPOSE:To make the connecting part miniaturized, by arranging an electric cable connecting part and an optical communication connecting part so that their positions are shifted in the longitudinal direction and fitting the body part of a bobbin, where the excess length of the optical communication line and the main body of the optical communication line connecting part are stored, to the outside circumference of the electric cable. CONSTITUTION:An electrooptic composite cable 1 consists of three stranded electric cables 2 and optical communication lines 3, a base layer 4 on the outside circumference of them, a coating layer 5 consisting of iron wires or the like, and a protection layer 6. In a connecting part 7, an electric cable connecting part 8 and an optical communication line connecting part 9 are arranged so that their positions are shifted in the longitudinal direction. The optical communication line connecting part 9 is formed with a bobbin 10 having collar parts 10B in both ends of a body part 10A and has the body part 10A fitted to the outside circumference of the electric cable 2 and is mounted. Optical communication lines 3 are inserted through collar parts 10B and are led out to the side of the body part 10A with an excess length and are sealed closely by packings 11A. Thus, the connecting part is made miniaturized. |
