Title:
COMPOSITE CABLE AND COMPOSITE HARNESS
Document Type and Number:
WIPO Patent Application WO/2017/109939
Kind Code:
A1
Abstract:
[Problem] To provide a composite cable and a composite harness in which buckling tends not to occur, and movement of a tape member in the direction of cable length can be inhibited. [Solution] The invention is provided with a pair of first electric wires 5, a twisted pair wire 8 in which a pair of second electric wires 6 having a smaller outer diameter than that of the first electric wires 5 are twisted together, a tape member 3 wound into a spiral around an assembly 9 in which the first electric wires 5 and the twisted pair 8 are twisted together, and a sheath 4 covering the outer periphery of the tape member 3. The twisting direction of the assembly 9 and the winding direction of the tape member 3 are the same, the tape member 3 and the sheath 4 have an inwardly projecting part 10 formed in a spiral along the direction of cable length and formed so as to enter inward in the valley part between both first electric wires 5 or the valley part between the first electric wire 5 and the twisted pair wire 8, and the length by which the inward projecting part 10 projects inward from a common tangent that passes through the outer perimeter of the first electric wires 5 or the first electric wire 5 and the twisted pair wire 8 is at least 3% of the outer diameter of the first electric wires 5.
