Abstract: The amount of air dielectric in air core coaxial and twinaxial cables is increased by spacer structures installed between the center conductor and the outer shield which have provision for air voids or pockets running lengthwise. The extra air space provides lower effective dielectric constant for the cable. In one embodiment, a single-element extruded spacer is formed with air cavities or voids that run continuously throughout the length of the spacer. Several spacer “profiles” or cross-sections are disclosed that place less solid dielectric mass in proximity to the center conductor. The result is a greater volume of air dielectric, and hence a lowered cable dielectric constant. In a further embodiment the spacer is a circular cross-sectioned element consisting of a central dielectric strength member surrounded with foamed material. Strength strands such as Kevlar® may be added to the spacer.

Abstract: A signal cable structure which automatically reduces or substantially eliminates selective frequency time shifting. The cable uses a unique cable lead structure in which the leads inside the cable are formed in a generally rectangular shape such that current passing through each segment of the signal cable is traveling in the opposite site direction from current passing through an adjacent segment of the signal cable. As the signal is passing through the signal cable, the magnetic fields generated in each segment of the signal cable cancel out the magnetic fields in adjacent segments. The cancellation of the magnetic fields eliminates the impedance which causes the selective frequency time shifting to occur. In signal cables having multiple leads, the leads are arranged such that they are offset from one another to maximize the distance between the leads reduce cross wire interference, and also rotated in relation to one another to further reduce cross wire interference.

Abstract: Existing electrical cables (such as low speed data, low or high speed computer or telephone cables) employ connectors having holes or other openings for receiving the insulation or requiring conductors having a precise pitch. For example, a mechanical part of the connector may close over the received cables, piercing the insulation and making an electrical contact with the conductor inside the insulation. Or, the insulation may also be used to provide the spacing required for mass termination of insulation such as connectors which require a specified pitch. This dimension or pitch is supplied by the inner insulation while the outer insulation supplies the dimension required to meet the impedance/capacitance requirements of the electrical circuits involved. The modern high speed data cables must have substantially more insulation so that the capacitive loading or impedance match of the wire is at an acceptable level.
