Abstract
Abstract An improved miniaturized electrical bus conductor is detailed comprising laminated thin parallel conductor strips which are separated and encapsulated by insulating material. The structure of the conductive strips is such that at spaced positions along the length of the bus conductor there is a non-overlapping relationship across the full width of the bus conductor so that the electrical bus conductor can be cut to a desired length at these non-overlapping positions without shorting the conductor strips.

Claim 1
Independent Claim
217 words
An elongated continuous electrical bus conductor adapted to be cut into a plurality of segments at overlapping aperture portions intermediate the ends of the bus conductor without deformation which would cause electrical shorting, and comprising first and second conductor strips positioned parallel to one another, and an insulating layer between said first and second conductor strips, each of said first and second conductor strips having at least one aperture portion provided therein intermediate its end points, said at least one aperture portion in said first conductor strip being rectangular and cut symmetrically relative to the transverse center of said first conductor strip with a Transverse extension greater than one-half the width of the bus conductor, and said at least one aperture portion in said second conductor strip extending transversely from opposed side edges of said second conductor strip with a transverse extension greater than one-half and less than the width of the bus conductor, said aperture portions being longitudinally aligned and transversely overlapped, with the first and second conductor strips being in non-overlapping relationship across the full width of the bus conductor where the aperture portions overlap, whereby the electrical bus conductor can be cut into segments at the aligned overlapped aperture portions without deformation that would cause the first and second conductor strips to make contact.
