Abstract
An electrical ribbon cable includes an insulated conductor extending along a longitudinal axis of the cable. The cable also includes a shielding film that carries the insulated conductor. The shielding film has a variable thickness defining a thickened rib portion and a thinned connecting portion, these portions being electrically conductive and extending along the longitudinal axis. The insulated conductor is disposed proximate the rib portion. The insulated conductor may be one of multiple insulated conductors that are organized into multiple conductor sets including at least a first and second conductor set, each conductor set including one or more of the insulated conductors, and the rib portion may be disposed between the first and second conductor sets.
Claims6
A shielded electrical cable, comprising:
- a conductor set comprising adjacent first and second insulated conductors extending along a length of the cable;
- and
- first and second shielding films disposed on opposite sides of the cable, each shielding film comprising a thinned connecting portion disposed between and connecting two thickened electrically conductive rib portions, the connecting and rib portions extending along the length of the cable, the rib portions of the first and second shielding films aligned with one another, aligned rib portions of the first and second shielding films spaced apart from each other along a thickness direction of the cable and defining a gap therebetween, the first and second insulated conductors disposed between the connecting portions and the aligned pairs of the rib portions of the first and second shielding films, wherein the first and second shielding films encompass at least 75% of the conductor set.
