Abstract

An electric power busway system includes a plurality of closely spaced bus bar conductors with each bus conductor having at least one integrally formed contact blade extending therefrom. The contact blades engage corresponding contact spring type receiver stabs within a power take-off assembly with interphase insulators arranged between the corresponding blade receiver stabs.

Claims

1. An electric bus bar comprising:

a rectangular metal bar including a double-edged body member;

slot means defining an opening through said body member through one edge thereof; and

contact blade means integral with said metal bar and extending from said one edge on a side of said slot opposite said body member.

2. The electric bus bar of claim 1 including a pair of angulated side arms integral with said contact blade and extending on either side thereof.

3. The electric bus bar of claim 1 wherein said slot means comprises a truncated slot.

4. An electric bus bar system comprising:

a plurality of rectangular metal bars arranged side-by-side in a linear array, each of said metal bars being electrically insulated on both sides and each of said metal bars including an integrally formed contact blade extending from one edge thereof; and

means defining an opening through each of said metal bars through said one edge and said integrally formed contact blade forming one side of said opening.

5. The electric bus bar system of claim 4 wherein each of said integrally formed contact blades are offset from each other.

6. The electric bus bar system of claim 4 wherein said opening comprises a truncated slot.

7. The electric bus bar system of claim 4 including a tin or silver coating on each of said contact blades.
