Abstract
Abstract A bus bar constructed to bend connector posts and make electrical contact with them at three loci of bar points. In vertical section, vertical lines between first and second bus contact points are spaced from third bus contact points adjacent said vertical lines by a distance less than the thickness of the posts, the locus defined by said vertical lines corresponding generally with a locus of post centerlines.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
175 words
In an easily attachable bus bar to interconnect a number of connector posts, the center lines of said posts defining a post locus, the improvement comprising: a first portion having, in vertical section, first and second contact points, said first portion having an intermediate portion between said first and second points spaced in a first direction transversely to vertical lines connecting said first and second points, and a second portion integrally connected to said first portion and spaced from said first portion in a second direction opposite to said first direction, said second portion having, in vertical section, third contact points adjacent to said intermediate portion and spaced in said second direction from said vertical lines by a distance less than the thickness of said posts, said first, second, and third contact points defining a post-insertion region between them, said bar being constructed to bend said posts when said bar is attached to them to provide the normal force for electrical contact, the locus defined by said vertical lines corresponding generally to said post locus.
Claim 2
Dependent Claim
175 words
In an easily attachable bus bar to interconnect a number of connector posts, the center lines of said posts defining a post locus, the improvement comprising: a first portion having, in vertical section, first and second contact points, said first portion having an intermediate portion between said first and second points spaced in a first direction transversely to vertical lines connecting said first and second points, and a second portion integrally connected to said first portion and spaced from said first portion in a second direction opposite to said first direction, said second portion having, in vertical section, third contact points adjacent to said intermediate portion and spaced in said second direction from said vertical lines by a distance less than the thickness of said posts, said first, second, and third contact points defining a post-insertion region between them, said bar being constructed to bend said posts when said bar is attached to them to provide the normal force for electrical contact, the locus defined by said vertical lines corresponding generally to said post locus.
Claim 3
Dependent Claim
34 words
The bar of claim 1 wherein said bar has a J-shaped cross-section, said first portion being the longer side, said second portion being the shorter side, said contact points being located on interior surfaces.
Claim 4
Dependent Claim
31 words
The bar of claim 2 wherein the end adjacent said first point is bent in said first direction, and the end adjacent said third point is bent in said second direction.
Claim 5
Dependent Claim
12 words
The bar of claim 1 wherein said bar is made of copper.
Claim 6
Dependent Claim
25 words
The bar of claim 4 wherein said copper is plated with material selected from the group consisting of tin over nickel and gold over nickel.
Claim 7
Dependent Claim
15 words
The bar of claim 5 wherein dielectric tape covers the exterior surface of said bar.
Claim 8
Dependent Claim
33 words
The bar of claim 1 wherein said first and second portions extend along a longitudinal axis passing transversely through said vertical lines and are substantially the same, in vertical section, along said axis.
Claim 9
Dependent Claim
64 words
The bar of claim 1 or 2 wherein said first and second portions extend along a longitudinal axis passing transversely through said vertical lines and are substantially the same, in vertical section, along said axis, and wherein said first and second portions are continuously connected to each other along said axis so that the tops of said posts do not extend through said bar.
