Patent ID: 7288726

Claim:
A hollow wire comprising: a base board; a first main wire and first and second, separated and co-axial sections of a first sub-wire, with the first main wire and the first and second sections of the first sub-wire each having a bottom surface located on the base board, with the first main wire located intermediate and spaced from the first and second sections of the first sub-wire, with the first main wire and the first and second sections of the first sub-wire each having a top surface, with the top surfaces of the first main wire and the first and second sections of the first sub-wire being flush; first and second portions of conductive material respectively located on two ends of the first main wire and spaced from each other; third and fourth portions of conductive material respectively located on the first and second sections of the first sub-wire and being spaced from each other, with the first, second, third and fourth portions of conductive material being spaced from each other, with a bottom surface of the first and second portions of conductive material located on the top surface of the first main wire, with a bottom surface of the third and fourth portions of conductive material located on the top surface of the first and second sections of the first sub-wire, wherein a top surface of the first, second, third, and fourth sections of conductive material is flush with each other; first and second separated and coaxial sections of a sub-wire axially formed on the top surface of the first and second sections of conductive material on the first main wire; and a second main wire connected across the third and fourth sections of conductive material on the first and second sections of the first sub-wire, with the first main wire located beneath the second main wire, with the second main wire located intermediate and spaced from the first and second sections of the second sub-wire, with the second main wire and the first and second sections of the second sub-wire havinig a bottom surface located on the top surfaces of the first, second, third and fourth sections of conductive material.
