Abstract
Abstract A buss bar for electrically coupling a plurality of electrical terminal posts or wires including a generally tubular elongated body formed of electrical conducting material which defines a slot extending substantially along the entire lateral side of the body, a plurality of holes or apertures arranged in pairs such that one of the holes of each pair is positiond in the upper surface of the body and one of the holes of each pair is positioned in the lower surface of the body to allow one of the terminal posts to be positioned through each of the aperture pairs, a groove or other similar indentation along the opposite side of the body from the slot and extending inward into the center of the body such that the interior surface of the groove is in a position of abutment with a terminal post positioned through the upper and lower holes, the amount of lateral pressure exerted by this interior pressure exerting surface upon the terminal posts being variable proportionally in response to the width of the slot located on the opposite side of the terminal post, the electrical communication being provided by the electrical conducting material from which the body is made and by the secure and efficient electrical connection provided between the terminal post and the three points of contact which are the edges of the upper and lower holes and the pressure surface. The body may also have about the outer surface thereof a coating of electrical insulating material to minimize electrical contact with the surrounding environment.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
160 words
For use with a plurality of electrical terminal posts, a buss bar comprising: (a) an elongated generally tubular body of electrically conducting material, said body defining a slot extending laterally along a side thereof; (b) said body defining a plurality of pairs of apertures, each pair of apertures including an upper hole positioned in the upper portion of said body and a lower hole position in the lower portion of said body, each of said pairs of apertures being adapted to receive therethrough an electrical terminal post to provide electrical communication between posts positioned within each pair of apertures; and (c) a pressure surface on said body extending toward the center of said body to be in abutment with the terminal posts positioned extending through the pairs of said upper and lower holes, said pressure surface adapted to laterally bias the terminal posts into full electrical contact with edges of said upper and lower holes and with said pressure surface.
Claim 2
Dependent Claim
160 words
For use with a plurality of electrical terminal posts, a buss bar comprising: (a) an elongated generally tubular body of electrically conducting material, said body defining a slot extending laterally along a side thereof; (b) said body defining a plurality of pairs of apertures, each pair of apertures including an upper hole positioned in the upper portion of said body and a lower hole position in the lower portion of said body, each of said pairs of apertures being adapted to receive therethrough an electrical terminal post to provide electrical communication between posts positioned within each pair of apertures; and (c) a pressure surface on said body extending toward the center of said body to be in abutment with the terminal posts positioned extending through the pairs of said upper and lower holes, said pressure surface adapted to laterally bias the terminal posts into full electrical contact with edges of said upper and lower holes and with said pressure surface.
Claim 3
Dependent Claim
23 words
The buss bar as defined in claim 1 wherein said slot and said pressure surface are positioned at opposite sides of said body.
Claim 4
Dependent Claim
28 words
The buss bar as defined in claim 1 wherein said body is formed of a resilient deformable material to allow the width of said slot to be variable.
Claim 5
Dependent Claim
30 words
The buss bar as defined in claim 3 wherein variation of the width of said slot controls the amount of pressure exerted upon the terminal posts by said pressure surface.
Claim 6
Dependent Claim
30 words
The buss bar as defined in claim 3 wherein the width of said slot is proportioned to the distance which said pressure surface extends into the interior of said body.
Claim 7
Dependent Claim
33 words
The buss bar as defined in claim 1 wherein said pressure surface is responsive to an increase in the width of said slot to increase the pressure exerted laterally on the terminal posts.
Claim 8
Dependent Claim
23 words
The buss bar as defined in claim 1 wherein said body includes a coating of insulating material upon portions of the surfaces thereof.
Claim 9
Dependent Claim
15 words
The buss bar as defined in claim 7 wherein said coating is a plastic material.
Claim 10
Dependent Claim
36 words
The buss bar as defined in claim 1 wherein said body includes a groove extending laterally along one side thereof, the interior surface of said groove acting as said pressure surface by abutting the terminal posts.
Claim 11
Dependent Claim
19 words
The buss bar as defined in claim 1 further including a coating of electrically conducting material on said body.
Claim 12
Dependent Claim
13 words
The buss bar as defined in claim 10 wherein said coating is gold.
Claim 13
Dependent Claim
214 words
For use with a plurality of electrical terminal posts, a buss bar comprising: (a) an elongated tubular body of electrical conducting material, said body defining a slot extending laterally along a side thereof, said slot having a variable width; (b) said body defining a plurality of pairs of apertures, each pair of apertures including an upper hole defined by the upper portion of said body and a lower hole defined by the lower portion of said body, each of said pairs of apertures being adapted to receive therethrough an electrical terminal post to provide electrical communication between the posts positioned within each pair of apertures; (c) a pressure surface on said body positioned on the opposite side of the terminal posts from said slot and extending toward the center of said body to be in abutment with the terminal posts positioned extending through each pair of said upper and lower holes, said pressure surface adapted to bias laterally a terminal post into full electrical contact with edges of said upper and lower holes, said surface adapted to exert variable lateral bias in proportion to the adjusted width of said slot; (d) an electrically insulating coating on the outer surface of said body; and (e) electrically conductive coating on the inner surface of said body.
Claim 14
Dependent Claim
214 words
For use with a plurality of electrical terminal posts, a buss bar comprising: (a) an elongated tubular body of electrical conducting material, said body defining a slot extending laterally along a side thereof, said slot having a variable width; (b) said body defining a plurality of pairs of apertures, each pair of apertures including an upper hole defined by the upper portion of said body and a lower hole defined by the lower portion of said body, each of said pairs of apertures being adapted to receive therethrough an electrical terminal post to provide electrical communication between the posts positioned within each pair of apertures; (c) a pressure surface on said body positioned on the opposite side of the terminal posts from said slot and extending toward the center of said body to be in abutment with the terminal posts positioned extending through each pair of said upper and lower holes, said pressure surface adapted to bias laterally a terminal post into full electrical contact with edges of said upper and lower holes, said surface adapted to exert variable lateral bias in proportion to the adjusted width of said slot; (d) an electrically insulating coating on the outer surface of said body; and (e) electrically conductive coating on the inner surface of said body.
