Abstract: An electrical interconnect is provided with two or more conductors and a conductor support structure, such as a tube, wherein the tube wall includes conductor support sites distributed along the wall. The conductors extend along the wall and across the tube and are maintained in a spaced relationship with respect to one another by the wall and the conductor support sites, which can be perforations through the tube wall, the conductors being inserted through the perforations. The conductor support sites for each conductor can be orthogonally disposed with respect to the sites for other conductors, allowing the conductors to be maintained in a generally helical relationship and each conductor can form a square-wave or trapezoidal-wave pattern along the tube. The interconnect can include cladding about the conductors and tube, such as a ribbed jacket and braided wire shield, and the conductor support structure may be provided with ribbing.

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.

Abstract: Uniformly spaced insulating buttons support two signal conductors within a tubular cable. The signal conductors are twisted from 180 to 360 degrees and are in physical contact with each other at their crossing point between each pair of buttons. Between each pair of buttons one of the conductors is covered with an insulating sleeve. The insulating sleeve alternates from one conductor to the other over the length of the cable. The conductors and buttons are enclosed within an insulating and supporting tubing. The supporting tubing is reduced in diameter or has corrugations to provide flexibility between each pair of insulating buttons. An overall shield composed of wires or foil is woven or helically wrapped to form a straight tube that surrounds the supporting tubing. The overall shield is electrically connected to system ground at the source end, allowing current flow only in the signal conductors.

Abstract: Two insulated signal conductors are wrapped in a double-helix fashion around a substantially straight third insulated ground conductor to form an interconnect. The first signal conductor is wrapped in a clockwise direction around the ground conductor. The second signal conductor is wrapped in a counter-clockwise direction around the ground conductor and first signal conductor, creating a spaced twisted-pair of the two signal conductors. The wrap frequency of the second conductor is lower than the wrap frequency of the first conductor. The difference in wrap frequencies of the first and second conductors is controlled such that the lengths of the first and second conductors are equal regardless of the length of the ground conductor. The wrap frequencies of the first and second signal conductors around the ground conductor are also chosen such that their intersections will be substantially orthogonal.
