Storage battery having molded-in terminal
View Patent ↗A storage battery includes a generally rectangular container having opposed side walls, end walls, a bottom wall and an open top defining a container interior. The container interior is divided into a plurality of cells supporting positive and negative plates. The plates include aligned positive lugs and aligned negative lugs. A pair of conductive straps are provided. One of the straps interconnects the positive lugs while the other strap interconnects the negative lugs. A tombstone extends from each of the straps. Each tombstone is located at a position spaced inwardly from the container walls. A pair of battery terminals are supported within the container end walls. Each battery terminal is directly connected to one of the tombstones. The battery terminals are positioned between the tombstone and the container wall and include a termination location adjacent the container wall for direct disconnectable termination thereat. A cover is provided for enclosing the open end of the container.
1. A storage battery comprising:
a generally rectangular container having opposed side walls, end walls including a front wall, a bottom wall and an open upper end defining a container interior and a container footprint;
said container interior being divided into a plurality of cells supporting positive and negative plates, said plates including aligned positive lugs and aligned negative lugs;
a cover structure for enclosing said open upper end of said container;
a pair of conductive straps, one said strap interconnecting said positive lugs and another said strap interconnecting said negative lugs, the pair of conductive straps each having an outboard edge facing toward the front wall and an inboard edge facing away from the front wall;
a tombstone extending upwardly from the inboard edge of each strap, each said tombstone having a generally planar transversely directed face, each said tombstone being integrally formed with each strap, each said tombstone being located at a position spaced inwardly from said container walls with said strap extending toward the front wall therefrom with said tombstone and said extending strap being within said container footprint; and
a pair of battery terminals supported within said cover and contained within said container footprint, each said terminal extending along a central axis transversely away from the transversely directed face of a respective one of said tombstones, each said terminal including a bushing and an insert, the bushing having an outer surface noncircular in cross-section, the cross-section being taken generally perpendicular to said central axis adjacent said container wall, said insert including a connection end and said bushing including a generally planar termination end, the bushing of each said battery terminal including a weldment directly connecting the planar termination end to the planar transversely directed face of the respective one of said tombstones, each said battery terminal being positioned between said tombstone and said container wall and said insert including an opening adjacent said container wall for direct disconnectable termination at said container wall.
2. The storage battery of claim 1 wherein said terminating opening is internally screw threaded.
3. The storage battery of claim 1 wherein said cover structure includes a primary cover and a secondary cover.
4. The storage battery of claim 3 wherein said secondary cover extends along said open upper end of said container and said primary cover extends along said open upper end of said container and including a depending skirt extending about said container.
5. The storage battery of claim 4 wherein said battery terminals are formed within said primary cover.
6. The storage battery of claim 5 wherein:
said battery terminals are formed within an extent of said primary cover extending along one of said end walls; and
said battery terminals are molded into said primary cover.
7. The storage battery of claim 1 wherein said termination device includes a bus bar.
8. The storage battery of claim 1 wherein said strap and said tombstone form an L-shaped configuration.
9. The storage battery of claim 8 wherein said terminals are accommodated within said L-shaped configuration.
10. The storage battery of claim 1 wherein said strap extends from said tombstone towards an adjacent end wall.
11. A storage battery comprising:
a generally rectangular container having opposed side walls, end walls including a front wall, a bottom wall and an open upper end defining a container interior and a container footprint;
said container interior being divided into a plurality of cells supporting positive and negative plates, said plates including aligned positive lugs and aligned negative lugs;
a pair of conductive straps, one said strap interconnecting said positive lugs and another said strap interconnecting said negative lugs, the pair of conductive straps each having an outboard edge facing toward the front wall and an inboard edge facing away from the front wall;
a tombstone extending upwardly from the inboard edge of each strap, each said tombstone having a generally planar transversely directed face, each said tombstone being integrally formed with each strap, each said tombstone being located at a position spaced within said container footprint;
a primary cover supported over said container open upper end, said primary cover including an access port adjacent each said tombstone;
a pair of battery terminals supported within said primary cover within said container footprint, each said terminal extending transversely away from the transversely directed face of a respective one of said tombstones, including a connection end and a generally planar termination end;
a weldment directly between said planar termination end of each said battery terminal and the planar transversely directed face of the respective one of said tombstones, said weldment being applied through said access port of said primary cover; and
a secondary cover structure for enclosing said open upper end of said container.
