Abstract:
1. A method for designing a wire structure, comprising the steps of: setting N radial lines which radiate equiangularly outward from a center of a cross section of a wire main body; setting a circular design line, wherein the circular design line has a center of circle defined by the center of the cross section of the wire main body and has a first radius (R1); and designing N identical convex portions, each having a cross section bilaterally symmetric with respect to a corresponding one of the radial lines, each said convex portion being an outward extension of the wire main body, the center of the cross section of the wire main body being equidistant from a centroid of the cross section of each said convex portion, the cross section of each said convex portion having an apex in contact with both the circular design line and the corresponding one of the radial line; wherein N is an odd number greater than or equal to three; wherein each said convex portion is defined by a circular arc, the circular arc being defined by a third radius (R2), and the at least three convex portions are tangent to an externally tangent circle defined by the first radius (R1) greater than or equal to twice the third radius (R2); wherein the first radius (R1) is less than 0.134 mm; wherein the third radius (R2) of the circular arc is between 0.045 and 0.0475 mm; wherein a vertical distance between any two parallel tangent lines to a boundary of a cross section of the wire structure is less than 2.01 mm.
