Abstract
A structure for an electrical cable which may be used as a high-frequency signal transmission line and which includes a jacket which is highly permeable by fluids to reduce the time required for stabilization of impedance and transmission speed of the cable upon placement into an environment characterized by a fluid dielectric having a different dielectric constant. The permeable jacket also facilitates electrical connection to a shield conductor of the transmission line, exposed through apertures in the jacket, by use of electrically conductive potting materials, and without the need to remove any portions of the jacket surrounding the shield conductor to which electrical connection is to be made.
Claims10
A cable for carrying electrical signals, comprising:
- (a) at least one elongate conductor;
- (b) a dielectric layer extending longitudinally of said cable and surrounding said conductor;
- (c) a shield layer of electrically conductive material extending longitudinally of said cable and surrounding said dielectric layer;
- and
- (d) a fluid-permeable jacket surrounding said shield layer and providing mechanical support therefor, said jacket including at least one elongate member wrapped helically about said shield layer and defining a plurality of helical turns, adjacent ones of said helical turns being spaced apart from each other longitudinally of said cable so as to expose portions of said shield layer therebetween.
An elongate cable for carrying electrical signals, comprising:
- (a) at least two elongate electrical conductors, including a twisted pair of conductors extending generally parallel with each other and longitudinally of said cable;
- (b) at least each of said twisted pair of said electrical conductors having a layer of a dielectric material associated therewith;
- (c) a shield conductor surrounding said at least two conductors and said dielectric material;
- and
- (d) a fluid-permeable jacket surrounding said electrical conductors and said layer of said dielectric material and providing mechanical support thereto, said jacket including at least one elongate member wrapped in helical turns about said electrical conductors, adjacent ones of said helical turns of said elongate member being spaced apart from each other.
An elongate cable for carrying electrical signals, comprising:
- (a) at least two elongate electrical conductors, including a twisted pair of conductors extending generally parallel with each other and longitudinally of said cable;
- (b) at least said twisted pair of said electrical conductors having a layer of a dielectric material associated therewith;
- and
- (c) a fluid-permeable jacket surrounding said electrical conductors and said layer of said dielectric material and providing mechanical support thereto, said jacket including a pair of elongate members wrapped in opposing helical turns about said electrical conductors, adjacent ones of said helical turns of each of said elongate members being spaced apart from each other.
A method of making an electrical connection, comprising:
- (a) providing a signal transmission line including at least one elongate conductor, a dielectric layer extending longitudinally of and surrounding said conductor, a shield layer of electrically conductive material extending longitudinally of and surrounding said dielectric layer and facing outwardly therefrom, and a fluid-permeable jacket surrounding said shield layer and including at least one elongate member of a dielectric material wrapped helically about said shield layer and defining a plurality of helical turns, adjacent ones of said helical turns being spaced apart from each other and exposing portions of said shield layer therebetween;
- and
- (b) surrounding a portion of said jacket with an electrically conductive potting material and bringing said potting material into electrical contact with at least some of said portions of said shield layer exposed between said adjacent ones of said helical turns.
