Abstract
An electrical cable assembly in which the conductive and dielectric elements are arranged in a composite with a conductive I-beam shaped geometry in which the conductive element is perpendicularly interposed between two parallel dielectric and ground plane elements. Low cross talk and controlled impedance are found to result from the use of this geometry.
Claims24
An electrical cable assembly comprising a metallic element generally perpendicularly interposed between transversely opposed first and second dielectric elements, wherein each of said transversely opposed dielectric elements includes a grounding means and consists of a pair of opposed lateral dielectric flanges, such that a pair of voids is formed in opposed lateral relation to said metallic element and each of said pair of voids is transversely interposed between one of said flanges in the first dielectric element and one of said flanges in the second dielectric element.
A method of reducing cross talk and controlling impedance in an electrical cable assembly having a conductor means carrying electrical signals comprising the steps of providing a transversely opposed first and a second dielectric base means and interposing said electrical conductor means between said first and second dielectric base means in generally perpendicular relation and providing a means for grounding said first and second dielectric base means, wherein each of the dielectric base means includes a grounding means and consists of a pair of Opposed lateral dielectric flanges, such that a pair of voids is formed in opposed lateral relation to said electrical conductor means and each of said pair of voids is transversely interposed between one of said flanges in the first dielectric base means and one of said flanges in the second dielectric base means.

- (c) an elongated central dielectric web element having opposed edges and opposed lateral sides and being perpendicularly interposed between said dielectric flange elements such that each of said opposed edges is fixed to one of the inner surfaces of the dielectric flange elements;
- and
- (d) a conductive layer superimposed over at least part of one of the lateral surfaces of the web element wherein there are a pair of voids positioned in opposed lateral relation to said web element and interposed between said flanges.
An electrical cable assembly comprising:
- (a) a first section comprising:
- (i) a pair of spaced parallel elongated dielectric flange elements each having an inwardly facing interior surface and an opposed exterior surface;
- (ii) a conductive layer superimposed over at least part of the exterior surfaces of said flange elements;
- (iii) an elongated central dielectric web element having opposed edges and opposed lateral sides and being perpendicularly interposed between said dielectric flange elements such that each of said opposed edges is fixed to one of the inner surfaces of the dielectric flange elements;
- and
- (iv) a conductive layer superimposed over at least part of one of the lateral surfaces of the web element and;
- (b) a second section comprising:
- (i) a second pair of spaced parallel elongated dielectric flange elements each having an inwardly facing interior surface and an opposed exterior surface;
- (ii) a second conductive layer superimposed over at least part of the exterior surfaces of said flange elements;
- and
- (iii) a second elongated central dielectric web element having opposed edges and opposed lateral sides and being perpendicularly interposed between said dielectric flange elements such that each of said opposed edges is fixed to one of the inner surfaces each of said pair of spaced parallel elongated dielectric flange elements in the second section abuts one of said pair of spaced parallel elongated dielectric flange elements in the first section, such that a void is formed between the elongated central dielectric web element and the second central dielectric web element.
