Abstract
A lead wire for use with an oxygen sensor is disclosed. The wire is formed of a center strand having high tensile strength surrounded by a plurality of first strands having high electrical conductance and a plurality of second strands having high tensile strength. The first and second strands are surrounded by a plurality of third strands having high electrical conductance and arranged in groups, and a plurality of fourth strands having high tensile strength, each fourth strand being positioned between two groups of third strands. The second and fourth strands are spaced at equal separation angles around the center strand.
Claims25
A lead wire for use with an oxygen sensor, said lead wire comprising:
- an elongate center strand having a relatively high tensile strength;
- a plurality of elongate first strands, each having a relatively high electrical conductance, said first strands being arranged circumferentially in spaced relation around said center strand;
- a plurality of elongate second strands, each having a relatively high tensile strength, said second strands being arranged circumferentially in spaced relation around said center strand and between said first strands in an alternating pattern;
- a plurality of elongate third strands having a relatively high electrical conductance, said third strands being arranged circumferentially in a plurality of groups around said first and second strands, each of said groups having a predetermined number of said third strands;
- and
- a plurality of elongate fourth strands having a relatively high tensile strength, said fourth strands being arranged circumferentially around said first and second strands, each of said fourth strands being positioned between two of said groups of said third strands.
A lead wire for use with an oxygen sensor, said lead wire comprising:
- an elongate center strand having a relatively high tensile strength;
- three elongate first strands, each having a relatively high electrical conductance, said first strands being arranged circumferentially in spaced relation around said center strand;
- three elongate second strands, each having a relatively high tensile strength, said second strands being arranged circumferentially in spaced relation around said center strand and between said first strands in an alternating pattern;
- nine elongate third strands having a relatively high electrical conductance, said third strands being arranged circumferentially in three groups of three strands around said first and second strands;
- and
- three elongate fourth strands having a relatively high tensile strength, said fourth strands being arranged circumferentially around said first and second strands, each of said fourth strands being positioned between two of said groups of said third strands.
