Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
200 words
In combination, a storage battery having a wall formed of an insulating material having a hole therethrough, a metallic terminal extending through said hole in sealing relationship with said wall, said terminal having a cylindrical portion on the external side of said wall, an upstanding flange on said wall surrounding said cylindrical portion and extending outwardly beyond the distal end of said terminal, said terminal having a centrally disposed cylindrical boss defining with said flange an annular open top groove surrounding said boss, said terminal having an internally threaded, axial blind hole opening onto said distal end, an electric cable having a terminal connector affixed thereto, said terminal connector including, a terminal plate having an opening therethrough in alignment with said hole in said terminal, said terminal plate having a depending annular portion surrounding said opening and abutting said distal end of said terminal, a plastic, insulating cover molded directly over said terminal plate and having an annular, resilient lip portion extending into said groove, and a terminal bolt extending through said opening and threaded into said hole and holding said terminal plate in contact with said distal end of said terminal and said lip in compression in said groove.
Claim 2
Dependent Claim
200 words
In combination, a storage battery having a wall formed of an insulating material having a hole therethrough, a metallic terminal extending through said hole in sealing relationship with said wall, said terminal having a cylindrical portion on the external side of said wall, an upstanding flange on said wall surrounding said cylindrical portion and extending outwardly beyond the distal end of said terminal, said terminal having a centrally disposed cylindrical boss defining with said flange an annular open top groove surrounding said boss, said terminal having an internally threaded, axial blind hole opening onto said distal end, an electric cable having a terminal connector affixed thereto, said terminal connector including, a terminal plate having an opening therethrough in alignment with said hole in said terminal, said terminal plate having a depending annular portion surrounding said opening and abutting said distal end of said terminal, a plastic, insulating cover molded directly over said terminal plate and having an annular, resilient lip portion extending into said groove, and a terminal bolt extending through said opening and threaded into said hole and holding said terminal plate in contact with said distal end of said terminal and said lip in compression in said groove.
Claim 3
Dependent Claim
66 words
The combination set forth in claim 1 wherein said plastic insulating cover further includes an upstanding, generally cylindrical sleeve having an internal flange therein, and said terminal bolt being provided with a shoulder having an external diameter exceeding the material diameter of said internal flange, and said terminal bolt being disposed within said sleeve with said external flange positioned between said shoulder and said terminal plate.
Claim 4
Dependent Claim
19 words
The combination set forth in claim 2 comprising a cap sealably attached over the open end of said sleeve.
Claim 5
Dependent Claim
40 words
The combination set forth in claim 1 wherein said cover is compressed against said upstanding flange throughout a continuous area surrounding said terminal to provide an external auxiliary seal for preventing fumes from said battery from excaping to the ambient.
Claim 6
Dependent Claim
39 words
The combination set forth in claim 4 wherein said depending annular portion of said terminal plate comprises an embossment, and said terminal plate has an annular recess surrounding said opening on the side thereof opposite said depending annular portion.
Claim 7
Dependent Claim
24 words
The combination set forth in claim 5 comprising a metal washer positioned in abutment with said terminal plate against the bottom of said recess.
Claim 8
Dependent Claim
