Title:
MULTICORE CABLE
Document Type and Number:
WIPO Patent Application WO/2019/194033
Kind Code:
A1
Abstract:
This multicore cable comprises a plurality of two-core parallel wires, the plurality of two-core parallel wires being intertwined around one another. The two-core parallel wires are provided with: two conductors arranged in parallel in relation to the length direction of the two-core parallel wires; an insulating layer covering the periphery of the two conductors; first shield tape covering the periphery of the insulating layer in a state of being longitudinally applied to the insulating layer; a drain wire arranged on the inside of the first shield tape; and a sheath covering the first shield tape. A cross-section of the insulating layer perpendicular to the length direction of the two-core parallel wires is an elliptical shape, where the major axis is 1.7 to 2.2 times as long as the minor axis. There is a groove at a portion including an intersection between the outline of the elliptical shape and the perpendicular bisector of the major axis. Part of the drain wire is retained in the groove so as to protrude further out to the first shield tape side than the insulating layer, and the twist pitch of the intertwining of the two-core parallel wires is shorter than 250 mm.
