Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
166 words
An electrical grid assembly comprising first and second grid members, each of said grid members comprising parallel bus portions residing in the same plane and a plurality of uniformly spaced conductors extending therebetween, said conductors being offset from the plane of said bus portions, apertures defined in each bus portion in line with each conductor and intermediate each conductor in equally spaced relation, a pair of insulating members having facing spaced apart continuous walls with apertures therein spaced a multiple of the dimension between said in line apertures in said bus portions, each of said insulators receiving a bus portion of each grid member against one of said facing walls in such position that the apertures in one wall align with said in line apertures and the sidewall apertures in the other wall align with the intermediate apertures, and fastening means extending through the aligned apertures of each bus portion and its adjacent wall to secure each of said grid members to each of said insulators.
Claim 2
Dependent Claim
166 words
An electrical grid assembly comprising first and second grid members, each of said grid members comprising parallel bus portions residing in the same plane and a plurality of uniformly spaced conductors extending therebetween, said conductors being offset from the plane of said bus portions, apertures defined in each bus portion in line with each conductor and intermediate each conductor in equally spaced relation, a pair of insulating members having facing spaced apart continuous walls with apertures therein spaced a multiple of the dimension between said in line apertures in said bus portions, each of said insulators receiving a bus portion of each grid member against one of said facing walls in such position that the apertures in one wall align with said in line apertures and the sidewall apertures in the other wall align with the intermediate apertures, and fastening means extending through the aligned apertures of each bus portion and its adjacent wall to secure each of said grid members to each of said insulators.
Claim 3
Dependent Claim
38 words
The grid assembly of claim 1 wherein said insulators are generally U-shape in cross-section and include means upstanding from the bottom thereof between said walls to define with said walls channels for said bus portions adjacent either wall.
Claim 4
Dependent Claim
22 words
The grid assembly of claim 1 wherein said conductors of said first and second grid assemblies reside in essentially the same plane.
