Shielded Electrical Cable

Abstract

A shielded electrical cable includes a conductor set and two generally parallel shielding films disposed around the conductor set. The conductor set includes one or more substantially parallel longitudinal insulated conductors. The shielding films include a parallel portion wherein the shielding films are substantially parallel. The parallel portion is configured to electrically isolate the conductor set.

What is claimed is: 
     
         1 . A shielded electrical cable comprising:
 a conductor set including one or more substantially parallel longitudinal insulated conductors; and   two generally parallel shielding films disposed around the conductor set and including a parallel portion on each lateral side of the conductor set where the shielding films are substantially parallel, at least one of the parallel portions being folded and piecewise planar for electrically isolating the conductor set.   
     
     
         2 . The shielded electrical cable of  claim 1  further comprising an adhesive layer adhering the shielding films to each other in each parallel portion. 
     
     
         3 . The shielded electrical cable of  claim 1 , wherein the shielding films make direct electrical contact with each other in at least one location of at least one of the parallel portions. 
     
     
         4 . The shielded electrical cable of  claim 1 , wherein at least one of the parallel portions includes an opening in at least one location of the parallel portion. 
     
     
         5 . The shielded electrical cable of  claim 1 , wherein at least one of the shielding films includes a break in at least one location of at least one of the parallel portions. 
     
     
         6 . A shielded electrical cable comprising:
 at least two spaced apart conductor sets arranged in a single plane, each conductor set including one or more substantially parallel longitudinal insulated conductors; and   two generally parallel shielding films disposed around the conductor sets and including a parallel portion on each lateral side of each conductor set where the shielding films are substantially parallel, the parallel portion between adjacent conductor sets being folded and piecewise planar for electrically isolating the conductor sets from each other.   
     
     
         7 . The shielded electrical cable of  claim 6 , wherein the folded and piecewise parallel portion has an actual width and defines a minimum spacing between the adjacent conductor sets, a ratio of the actual width to the minimum spacing being at least 5.
