Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
227 words
An elongated unitary section of bus duct, said section comprising an elongated housing, a set of a plurality of elongated unitary bus bars, each of said bus bars comprising a pair of opposite wide faces and a pair of opposite narrow faces, said bus bars being supported in said housing in a generally stacked relationship with the wide faces thereof being in a faceto-face relationship, said set of bus bars comprising a first connecting end part at one end thereof and a second connecting end part at the other end thereof, said bus bars of each of said connecting end parts being spaced to receive additional bus bars and insulating means in a lap-type connection, said section being formed with a plurality of compact regions and a plurality of plug-in regions along the length of said section, at each of said compact regions said bus bars being sandwiched in a face-to-face compact relationship, at each of said plug-in regions said bus bars being spaced, a separate plug-in insulating means supported in said housing at each of said plug-in regions, each of said plug-in insulating means having opening means therein open at a narrow face side of said section for receiving plug-in elements, and said housing having opening means therein at each of said plug-in regions to provide access to said opening means in said plug-in insulating means.
Claim 2
Dependent Claim
227 words
An elongated unitary section of bus duct, said section comprising an elongated housing, a set of a plurality of elongated unitary bus bars, each of said bus bars comprising a pair of opposite wide faces and a pair of opposite narrow faces, said bus bars being supported in said housing in a generally stacked relationship with the wide faces thereof being in a faceto-face relationship, said set of bus bars comprising a first connecting end part at one end thereof and a second connecting end part at the other end thereof, said bus bars of each of said connecting end parts being spaced to receive additional bus bars and insulating means in a lap-type connection, said section being formed with a plurality of compact regions and a plurality of plug-in regions along the length of said section, at each of said compact regions said bus bars being sandwiched in a face-to-face compact relationship, at each of said plug-in regions said bus bars being spaced, a separate plug-in insulating means supported in said housing at each of said plug-in regions, each of said plug-in insulating means having opening means therein open at a narrow face side of said section for receiving plug-in elements, and said housing having opening means therein at each of said plug-in regions to provide access to said opening means in said plug-in insulating means.
Claim 3
Dependent Claim
78 words
An elongated unitary section of bus duct according to claim 1, said housing comprising a first pair of oppositely disposed housing members and a second pair of oppositely disposed housing members forming an elongated tubular housing, and said first pair of oppositely disposed housing members being disposed at the wide faces of the outermost bus bars of said set of bus bars to sandwich said set of bus bars therebetween in a compact relationship at said compact regions.
Claim 4
Dependent Claim
81 words
An elongated unitary section of bus duct according to claim 2, and said bus bars and each of said housing members of said first pair of housing members having a tortuous shape along the length thereof with said bus bars and said first pair of housing members extending inward to provide a compact sandwiched relationship at each of said compact regions and flaring outward at each of said plug-in regions providing space for plug-in capability at each of said plug-in regions.
Claim 5
Dependent Claim
42 words
A section of bus duct according to claim 2, said first pair of housing members being metallic heat conducting members for dissipating heat generated in said bus bars, and said second pair of housing members being mechanically rigid members for structural strength.
Claim 6
Dependent Claim
41 words
A section of bus duct according to claim 4, said first pair of housing members being members of a material selected from the group of aluminum and base alloys of aluminum, said second pair of housing members being members of steel.
Claim 7
Dependent Claim
42 words
A section of bus duct according to claim 3, said first pair of housing members being metallic heat conducting members for dissipating heat generated in said bus bars, and said second pair of housing members being mechanically rigid members for structural strength.
Claim 8
Dependent Claim
41 words
A section of bus duct according to claim 6, said first pair of housing members being members of a material selected from the group of aluminum and base alloys of aluminum, said second pair of housing members being members of steel.
Claim 9
Dependent Claim
58 words
An elongated unitary section of bus duct according to claim 1, each of said plug-in insulating means being rigid molded insulating means molded with barriers between adjacent bus bars and mOlded with a separate well cavity formed therein for each bus bar of said set of bus bars with adjacent well cavities being separate by insulating barrier means.
Claim 10
Dependent Claim
88 words
A section of bus duct according to claim 1, at each of said plug-in regions said insulating means having opening means therein open at each of the opposite narrow face sides of said section for receiving plug-in elements from each of the opposite narrow face sides of said section, and said housing having opening means therein at each narrow face side of each of said plug-in regions to provide access to said opening means in said plug-in means from each of the two opposite sides of said section.
Claim 11
Dependent Claim
59 words
A section of bus duct according to claim 9, and each of said insulating means comprising a pair of molded rigid insulating members each of which insulating members is disposed at a different one of said narrow face sides with each of said insulating members having opening means therein to provide plug-in capability at each of said plug-in regions.
