Abstract:
1. An anchor for use in creating a termination on a cable, comprising: a. a neck anchor boundary; b. a distal anchor boundary; c. a central axis; d. a passage extending along said central axis from said neck anchor boundary to said distal anchor boundary; e. wherein said passage is defined by a revolved wall profile; f. wherein said wall profile is created by adding a first set of radius values produced by a first curve and a second set of radius values produced by a second curve to form a third set of radius values defining a composite curve; g. wherein a Cartesian coordinate system is defined with an x-axis lying along said central axis, an origin lying distal to said neck anchor boundary in the direction of said distal anchor boundary, and a y-axis being perpendicular to said x-axis so that said radius values correspond to the variable y and the distance along said central axis from said origin corresponds to the variable x; h. wherein at each point along said x-axis said composite curve has a slope, with a negative slope being defined as one which causes said passage to shrink when proceeding in the direction from said distal anchor boundary to said neck anchor boundary; i. wherein said first curve is an area ratio function having a negative slope proximate said neck anchor boundary and having an increasingly negative slope proceeding toward said distal anchor boundary, said area ratio function assuming the form y=Ae j. wherein said second curve is a tensile stress modifier curve having a positive slope, said tensile stress modifier curve assuming the form y=Dx+E ; and k. wherein parameters defining said area ratio function and said tensile stress modifier curve are selected so that at said neck anchor boundary said radius of said composite curve is approximately equal to the radius of said cable and said slope of said composite curve is approximately zero.
