Low profile flat cables for twisted pairs

摘要

The flat cable comprises several wires arranged as twisted pairs, each wire comprising an inner conductive core surrounded by insulation. An outer insulative sheath surrounds the twisted pairs, the outer insulative sheath comprising an extruded member having a cosntant cross-section throughout its length. The insulative sheath comprises a hollow envelope. The insulative sheath has several longitudinally extending adjacent compartments with a single twisted pair of each adjacent compartment. The interior of the sheath is constricted between each compartment such that the sheath prevents lateral movement of each twisted pair from its respective compartment. The outer sheath is resistant to shearing and all of the twisted pairs can be freed from the outer sheath by longitudinally cutting the outer sheath at any one position adjacent an end of the cable.
