Abstract
A new jacketing construction for use with coaxial cables provides an improved level of crush and impact resistance. The jacketing construction comprises a plurality of circumferentially spaced tubes each having a nonsymmetrical cross-sectional geometry such that under load, a portion of any radially transmitted force will be dissipated.

A cable for use in transmitting electromagnetic signals comprising:
- an inner electrical conductor;
- an electrical insulating layer concentrically encompassing said inner electrical conductor;
- an outer electrical conductor concentrically encompassing said insulating layer;
- and
- an outer jacket encompassing said outer electrical conductor, said outer jacket formed from a deformable material having a plurality of spaced tubular elements arranged longitudinally about said outer electrical conductor, each of said tubular elements having a cross-section which is non-symmetrical about all radii of said inner electrical conductor, and having an arch-shaped outer layer portion with a radius of curvature less than the average distance between the outer layer portion and the longitudinal axis of said cable, the radial axis of each arch-shaped outer layer portion being non-radial of said cable.

A jacket for protecting an elongated member such as an electrical cable, said jacket comprising:
- an inner wall of generally circular cross-section to surround and closely conform to an elongated member;
- a deformable outer wall;
- and
- a plurality of deformable support walls spaced around said inner, wall, between said inner and outer walls, to support said outer wall, said plurality of deformable support walls together with said inner and outer walls defining longitudinally extending tubular chambers, each portion of said outer wall spanning two adjacent support walls being arch-shaped with a radius of curvature less than the average distance between the outer wall and the center of the jacket, and the radial axis of each of said arch-shaped portions being non-radial of the jacket.
