ABSTRACT:
An improved twisted-pair interconnect includes a first conductor and second conductor. Over the first half of the interconnect the first conductor is uninsulated and the second conductor is insulated. Over the second half of the interconnect the first conductor is insulated and the second conductor is uninsulated. An insulation barrier is provided at the midpoint of the interconnect to prevent shorting. In a further improvement, the twisted-pair cable is constructed from an insulated and an uninsulated conductor which are twisted together, severed at a midpoint, and reconnected with the conductors swapped, causing each conductor to be half-insulated and both conductors to have the same length. To reduce electromagnetic coupling and preventing external contact with the uninsulated conductors, the twisted-pair can be enclosed by flexible straight or grooved gas-filled tubing. The grooves can be radial, axial or helical and serve to center the twisted-pair within the tubing while contacting the twisted-pairs as little as possible. Multiple twisted-pairs of the invention, each enclosed by a flexible tubing section, can also be bundled together and connected in parallel to form an improved loudspeaker interconnect.
