Abstract
A coaxial cable comprises inner and outer conductors disposed along an elongate axis, a dielectric insulating material disposed between the inner and outer conductors, a compliant outer jacket disposed over the inner and outer conductors, and a reinforcing outer jacket disposed over the compliant inner jacket, the outer jacket being physically separate from the inner jacket and comprising on-axis and off-axis fibers disposed in a binding matrix, the outer jacket comprising more on-axis than off-axis fibers.
Claims31
A cable comprising:
- an inner conductor extending along an elongate axis;
- an insulator receiving the inner conductor and extending along the elongate axis;
- an outer conductor receiving the insulator and extending along the elongate axis;
- a separating foil disposed between the insulator and the outer conductor, the separating foil facilitating separation and insertion of a post sleeve of a coaxial cable connector;
- an insulating jacket receiving the outer conductor and extending along the elongate axis, the insulating jacket configured to electrically insulate the inner and outer conductors from an electrical ground;
- a structurally reinforcing jacket disposed over the insulating jacket and extending along the elongate axis, the structurally reinforcing jacket configured to structurally augment and puncture-protect the cable axially along the elongate axis;
- and
- a separating material interposing the insulating and structurally reinforcing jackets, the separating material facilitating separation and insertion of a retention post,
- wherein the structurally reinforcing jacket including reinforcing fibers disposed in a binding matrix material, the binding matrix having inner and outer portions, the outer portion including a radius dimension greater than one half of the total radius dimension,
- wherein the fibers reinforce the outer portion of the reinforcing jacket;
- wherein the reinforcing fibers comprise fibers having high yield strength and low elastic modulus material properties, and a combination of on-axis and off-axis fibers, the on-axis fibers oriented at less than about twenty five degrees (+/−25°) relative to the elongate axis and the off-axis fibers oriented at greater than about thirty-five degrees (+/−35°) relative to the elongate axis;
- wherein the reinforcing fibers are selected from the group consisting of carbon, graphite, boron, fiberglass and polyparaphenylene terephthalamide fibers;
- and
- wherein the binding matrix material comprising a non-conductive, low modulus material from the group of elastomer, polyethylene and polyurethane.

- wherein the first and second cable sections each react and induce loads;
- wherein the loads conveyed by the first cable section are configured to be transferred from the first cable section into a support structure at a first location;
- and
- wherein loads conveyed by the second cable section are configured to be transferred from the second cable section into a support structure at a second location.
