Abstract
Abstract A contact assembly for connecting the terminals of a dry cell stack to the external terminals of a battery is described in which a conductive contact plate connects the top terminal of the cell stack to a first battery terminal. A connector strip nonconductively attached to the contact plate connects the bottom terminal of the stack with a second battery terminal. A method for assembling the connector assembly is also described.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
283 words
A dry cell battery contact assembly comprising: a. an electrically conductive contact plate having an upper and a lower surface; b. an electrically insulating coating overlying and adhered to at least a portion of the upper surface of the contact plate; and c. an electrically conductive connector strip having a first portion overlying and attached to a portion of the insulating coating and insulated from the contact plate thereby, the connector strip having a second portion substantially perpendicular to the first portion of the strip and having an end away from the first portion, whereby when the contact assembly is placed on the top of a cell pack having a lower and an upper terminal, a terminal board having two terminals mounted thereon and passing therethrough placed above the contact assembly, the end of the second portion of the connector strip away from the contact plate bent to touch and make electrical contact with the lower terminal of the cell pack, a bottom board placed below the bent portion of the contact strip and a sleeve placed around the entire assemblage and flanged against the top of the terminal board and the bottom of the bottom board, the first portion of the connector strip will make electrical contact with a first terminal on the terminal board, a portion of the lower surface of the contact plate will make electrical contact with a first terminal on the terminal board, a portion of the lower surface of the contact plate will make electrical contact with the upper terminal of the cell pack and a portion of the upper surface of the contact plate will make electrical contact with a second terminal on the terminal board.
Claim 2
Dependent Claim
283 words
A dry cell battery contact assembly comprising: a. an electrically conductive contact plate having an upper and a lower surface; b. an electrically insulating coating overlying and adhered to at least a portion of the upper surface of the contact plate; and c. an electrically conductive connector strip having a first portion overlying and attached to a portion of the insulating coating and insulated from the contact plate thereby, the connector strip having a second portion substantially perpendicular to the first portion of the strip and having an end away from the first portion, whereby when the contact assembly is placed on the top of a cell pack having a lower and an upper terminal, a terminal board having two terminals mounted thereon and passing therethrough placed above the contact assembly, the end of the second portion of the connector strip away from the contact plate bent to touch and make electrical contact with the lower terminal of the cell pack, a bottom board placed below the bent portion of the contact strip and a sleeve placed around the entire assemblage and flanged against the top of the terminal board and the bottom of the bottom board, the first portion of the connector strip will make electrical contact with a first terminal on the terminal board, a portion of the lower surface of the contact plate will make electrical contact with a first terminal on the terminal board, a portion of the lower surface of the contact plate will make electrical contact with the upper terminal of the cell pack and a portion of the upper surface of the contact plate will make electrical contact with a second terminal on the terminal board.
Claim 3
Dependent Claim
27 words
A dry cell battery contact assembly as defined in claim 1 in which the insulating material overlying a portion of the contact plate is an insulating plate.
Claim 4
Dependent Claim
28 words
A dry cell battery contact assembly as defined in claim 1 in which the electrically conductive contact plate and the electrically conductive connector strip are made of metal.
Claim 5
Dependent Claim
102 words
A dry cell battery contact assembly as defined in claim 2 in which: a. the insulating tape overlying the contact plate is fastened thereto by adhesive means and a portion of the tape covers a portion of the edge of the contact plate; b. the electrically conductive connector strip is fastened to the top of the insulating tape by adhesive means and the portion of the strip substantially perpendicular to the first portion is adjacent to the edge of the contact plate and insulated therefrom by the portion of the insulating tape covering the portion of the edge of the contact plate.
Claim 6
Dependent Claim
145 words
In a multicell dry cell battery of the type having an internal cell stack with electrical contacts at either end and external terminals at one end only of the battery and a contact strip within the battery for effecting electrical contact between the cell stack terminals and the battery terminals, the improvement in the contact strip which comprises: a. an electrically conductive contact plate having an upper and a lower surface; b. an electrically insulating sheet overlying and adhered to at least a portion of the upper surface of the contact plate; and c. an electrically conductive connector strip having a first portion overlying and attached to a portion of the insulating sheet and insulated from the contact plate thereby, the connector strip having a second portion substantially perpendicular to the first portion of the strip and having an end away from the first portion.
Claim 7
Dependent Claim
145 words
In a multicell dry cell battery of the type having an internal cell stack with electrical contacts at either end and external terminals at one end only of the battery and a contact strip within the battery for effecting electrical contact between the cell stack terminals and the battery terminals, the improvement in the contact strip which comprises: a. an electrically conductive contact plate having an upper and a lower surface; b. an electrically insulating sheet overlying and adhered to at least a portion of the upper surface of the contact plate; and c. an electrically conductive connector strip having a first portion overlying and attached to a portion of the insulating sheet and insulated from the contact plate thereby, the connector strip having a second portion substantially perpendicular to the first portion of the strip and having an end away from the first portion.
Claim 8
Dependent Claim
25 words
A multicell battery as defined in claim 5 in which the electrically conductive contact plate and the electrically conductive connector strip are made of metal.
