Abstract
Abstract A leakproof, side terminal battery of the thin-wall type comprising a terminal insert formed by injection molding a thermoplastic body about a conductive spool, which insert is mated with an aperture in the battery case wall and welded to a boss surrounding the aperture. The body includes a plug portion for insertion into the aperture and a flange portion for welding to the boss. The conductive spool preferably includes an extension projecting into the battery for fusing to the battery's innards at a location remote from the wall.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
125 words
In an electric storage battery having a molded thermoplastic container including a plurality of walls defining a cell chamber for the battery's innards, the improvement comprising: at least one of said walls having an aperture therein, a boss circumscribing said aperture on the outside of said container and a sealing rim on said boss; and a terminal insert sealing off said aperture, said insert comprising a conductive spool embedded in and passing through a thermoplastic body molded thereabout, said body having a plug portion extending in close fitting relation through said aperture, a flange portion on one end of said plug overlying and welded to said rim and a skirt depending from said flange and circumscribing the weldment formed between said rim and said flange.
Claim 2
Dependent Claim
125 words
In an electric storage battery having a molded thermoplastic container including a plurality of walls defining a cell chamber for the battery's innards, the improvement comprising: at least one of said walls having an aperture therein, a boss circumscribing said aperture on the outside of said container and a sealing rim on said boss; and a terminal insert sealing off said aperture, said insert comprising a conductive spool embedded in and passing through a thermoplastic body molded thereabout, said body having a plug portion extending in close fitting relation through said aperture, a flange portion on one end of said plug overlying and welded to said rim and a skirt depending from said flange and circumscribing the weldment formed between said rim and said flange.
Claim 3
Dependent Claim
131 words
In an electric storage battery having a molded thermoplastic container including a plurality of walls defining a cell chamber for the battery's innards, the improvement comprising: at least one of said walls having an aperture therein, a boss circumscribing said aperture on the outside of said container and a sealing rim on said boss; and a terminal insert sealing off said aperture, said insert comprising a conductive spool embedded in and passing through a thermoplastic body molded thereabout, said body having a plug portion extending in close fitting relation through said aperture, a flange portion on one end of said plug overlying and heat-fused to said rim and a skirt depending from the peripheral edge of said flange so as to circumscribe the fused joint between said rim and said flange.
