Abstract
Abstract A collective connection device for wire conductors of electrical power distribution systems accommodates a compact arrangement of a multiple number of smaller and larger terminal blocks on a busbar. The busbar of the device is divided into two primary decks respectively located at the first and second ends of the busbar and upper and lower centrally located decks which form an electrical bridge between the primary end decks.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
216 words
A collective connection device for wire conductors of an electrical distribution system having a multiple number of terminal blocks of the same potential, all of which are mechanically and electrically connected with a current collecting busbar, wherein a majority of said terminal blocks are designed for receiving wire conductors of smaller cross-section and a minority of the terminal blocks are designed for receiving wire conductors of larger cross-section, said busbar comprising: a first deck member which is formed from a flat material, said first deck member including an upper deck portion and a primary deck portion; and a second deck member which is formed from a flat material, said second deck member including a lower deck portion and a primary deck portion, said first and second deck members being received together in adjacent relation so that said upper and lower deck portions run substantially parallel to each other and so that said respective primary deck portions overlie each other and cooperate to form an integral primary deck having a total current carrying cross-section that is greater than said upper and lower deck portions, said terminal blocks for receiving larger cross-section wire conductor being arranged on said primary deck, said terminal blocks for receiving smaller cross-section wire conductors being arranged only on said upper and lower decks.
Claim 2
Dependent Claim
216 words
A collective connection device for wire conductors of an electrical distribution system having a multiple number of terminal blocks of the same potential, all of which are mechanically and electrically connected with a current collecting busbar, wherein a majority of said terminal blocks are designed for receiving wire conductors of smaller cross-section and a minority of the terminal blocks are designed for receiving wire conductors of larger cross-section, said busbar comprising: a first deck member which is formed from a flat material, said first deck member including an upper deck portion and a primary deck portion; and a second deck member which is formed from a flat material, said second deck member including a lower deck portion and a primary deck portion, said first and second deck members being received together in adjacent relation so that said upper and lower deck portions run substantially parallel to each other and so that said respective primary deck portions overlie each other and cooperate to form an integral primary deck having a total current carrying cross-section that is greater than said upper and lower deck portions, said terminal blocks for receiving larger cross-section wire conductor being arranged on said primary deck, said terminal blocks for receiving smaller cross-section wire conductors being arranged only on said upper and lower decks.
Claim 3
Dependent Claim
103 words
A current collecting busbar for a collective connection device comprising: upper and lower decks each having first and second ends and a predetermined current carrying cross-section; said upper deck and said lower deck running substantially parallel to each other, said upper and lower decks including terminal blocks which are adapted for receiving small cross-section wire conductors, said upper deck and said lower deck merging at said first ends to form a primary deck having a total current carrying cross-section that is greater than said upper and lower decks, said primary deck including terminal blocks which are adapted for receiving larger cross-section wire conductors.
Claim 4
Dependent Claim
103 words
A current collecting busbar for a collective connection device comprising: upper and lower decks each having first and second ends and a predetermined current carrying cross-section; said upper deck and said lower deck running substantially parallel to each other, said upper and lower decks including terminal blocks which are adapted for receiving small cross-section wire conductors, said upper deck and said lower deck merging at said first ends to form a primary deck having a total current carrying cross-section that is greater than said upper and lower decks, said primary deck including terminal blocks which are adapted for receiving larger cross-section wire conductors.
Claim 5
Dependent Claim
41 words
In the current collecting busbar of claim 2, said upper deck and said lower deck further merging at said second ends to form an additional primary deck, thereby providing a primary deck at each end of said upper and lower decks.
Claim 6
Dependent Claim
31 words
In the current collecting busbar of claim 2, said primary deck including a connector slot therein which is adapted for receiving a jumper bar for electrically connecting two of said busbars.
Claim 7
Dependent Claim
33 words
In the current collecting busbar of claim 2, said upper deck and said lower deck being horizontally displaced from each other so that screw-type terminal blocks received thereon may be accessed from above.
Claim 8
Dependent Claim
14 words
The current carrying busbar of claim 2 further comprising a housing of insulation material.
Claim 9
Dependent Claim
30 words
In the current carrying busbar of claim 6, said housing including dovetail joints on opposing ends thereof, such that two or more housings may be joined together in linear alignment.
Claim 10
Dependent Claim
135 words
A current collecting busbar for a collective connection device comprising: a first deck member which is formed from a flat material, said first deck member including an upper deck portion and a primary deck portion; and a second deck member which is formed from a flat material, said second deck member including a lower deck portion and a primary deck portion, said first and second deck members being received together in adjacent relation so that said upper and lower deck portions run substantially parallel to each other and so that said respective primary deck portions overlap and cooperate to form an integral primary deck being located on opposite sides of said upper and lower deck portions and having a total current carrying cross-section that is grater than either of said upper and lower deck portions.
Claim 11
Dependent Claim
135 words
A current collecting busbar for a collective connection device comprising: a first deck member which is formed from a flat material, said first deck member including an upper deck portion and a primary deck portion; and a second deck member which is formed from a flat material, said second deck member including a lower deck portion and a primary deck portion, said first and second deck members being received together in adjacent relation so that said upper and lower deck portions run substantially parallel to each other and so that said respective primary deck portions overlap and cooperate to form an integral primary deck being located on opposite sides of said upper and lower deck portions and having a total current carrying cross-section that is grater than either of said upper and lower deck portions.
Claim 12
Dependent Claim
44 words
In the busbar of claim 8, said primary deck including at least one terminal block which is adapted for receiving a larger cross-section wire conductor, said upper and lower deck portions including multiple terminal blocks which are adapted to receive small cross-section wire conductors.
