Abstract
An electrical ribbon cable includes at least one conductor set having at least two elongated conductors extending from end-to-end of the cable. Each of the conductors are encompassed along a length of the cable by respective first dielectrics. A first and second film extend from end-to-end of the cable and are disposed on opposite sides of the cable The conductors are fixably coupled to the first and second films such that a consistent spacing is maintained between the first dielectrics of the conductors of each conductor set along the length of the cable. A second dielectric disposed within the spacing between the first dielectrics of the wires of each conductor set.
Claims8
An electrical ribbon cable, comprising:
- at least one conductor set comprising at least two elongated conductors extending from end-to-end of the cable, wherein each of the conductors are encompassed along a length of the cable by respective first dielectrics;
- a first and second shielding films extending from end-to-end of the cable and disposed on opposite sides of the cable, wherein the conductors are fixably coupled to the first and second shielding films such that a consistent spacing is maintained between the first dielectrics of the conductors of each conductor set along the length of the cable;
- and
- a second dielectric filling the space between the closest points of proximity between the first dielectrics of the conductors of each conductor set, wherein a dielectric constant of the first dielectrics is higher than a dielectric constant of the second dielectric.
