Abstract
A transmission cable for transmitting differential logic signals is disclosed having an improved shielding. The cable includes a pair of insulated signal conductors in side by side relation with a layer of electrically conductive material wrapped around the two signal conductors. A non-insulated drain wire is disposed axially along the outside of the wrap of shielding material adjacent one of the signal conductors. The layer of conductive material is continued around the outside of the drain wire thereby forming an additional wrap of the shielding about at least a part of the cable assembly. The drain wire is in electrical engagement with the shielding material.
Claims13
An electrical cable having at least two insulated conductors arranged side by side so that their axes define a plane, only one layer of shielding, and a non-insulated drain wire having its axis disposed substantially parallel with said plane, wherein said layer of shielding extends completely around said two insulated conductors for at least one wrap, but not therebetween, and at least an additional partial wrap of said layer of shielding over a portion of said at least one wrap, wherein said non-insulated drain wire is between said one and said partial wraps.
An electrical cable having at least two insulated conductors arranged side by side so that their axes define a plane, a layer of shielding, and a non-insulated drain wire having its axis disposed substantially parallel with said plane,
- wherein said layer of shielding extends completely around said two insulated conductors for at least one wrap, and said non-insulated drain wire is disposed outside said at least one wrap of said layer of shielding, including an additional at least partial wrap of said layer of shielding over a portion of said at least one wrap and said drain wire, said drain wire in electrical engagement with said layer of shielding.
An electrical cable comprising:
- at least two insulated conductors side by side, a layer of conductive shielding defining at least a first wrap completely around the insulated conductors, and said layer of shielding defining at least one additional wrap with one said additional wrap extending at least partially over another said wrap, and a conductive drain wire disposed between any two of said wraps and in electrical engagement with at least one of said wraps.
