Shielded electrical cable

摘要

A shielded electrical cable includes a conductor set, two generally parallel shielding films disposed around the conductor set, and a transition portion defined by the shielding films and the conductor set. The conductor set includes one or more substantially parallel longitudinal insulated conductors. The shielding films include a concentric portion substantially concentric with at least one of the conductors and a parallel portion wherein the shielding films are substantially parallel. The transition portion provides a gradual transition between the concentric portion and the parallel portion of the shielding films.

1. A shielded electrical cable comprising:
a conductor set including one or more substantially parallel longitudinal insulated conductors; a shielding film disposed around the conductor set; and two non-conductive polymeric layers disposed around the conductor set and including a concentric portion substantially concentric with at least one of the conductors having a first cross-sectional area and a parallel portion wherein the two non-conductive polymeric layers are substantially parallel; and a transition portion providing a gradual transition between the concentric portion and the parallel portion of the two non-conductive polymeric layers, the transition portion comprising a second cross-sectional area defined as an area between first transition points where the two non-conductive polymeric layers deviate from being substantially concentric with the at least one of the conductors and second transition points where the two non-conductive polymeric layers deviate from being substantially parallel, the second cross-sectional area being equal to or smaller than the first cross-sectional area.
