Abstract
A solderless battery pack. The pack has a generally thin wall cell body portion with two tubular segments each adapted to hold a plurality of batteries. An upper end cap and a lower end cap are provided for fitting tightly over the upper and lower ends of the cell body portion, respectively. The end caps are compressingly engaged to make electrical connection with the terminals of the uppermost and the lowermost batteries by use of opposing all-thread fasteners, or more preferably, by use of shrink wrap tubing. More preferably, instead of all-thread fasteners, a filament type strapping tape is utilized for wrapping the battery pack around a longitudinal exist to tightly compress batteries in each column of batteries. Then, the tape is covered by and further compressed with a tightly compressing shrink wrap material.
Claims19
A battery pack for holding a plurality of battery cells, each of said battery cells of the shape having an elongate body portion with an outer surface portion and opposing first and second ends, each of said first and second ends further comprising either a positive electrical terminal or a negative electrical terminal, said battery pack comprising:
- (a) a bottom end cap, said bottom end cap
- (i) shaped to fit along a portion of said outer surface portion of at least one of said plurality of battery cells, so as to receive therein in snug fitting fashion, transverse cross-sectionwise, at least some of said outer surface of said elongate body portion of said at least one of said plurality of battery cells,
- (ii) further comprising a first electrical contact, said first electrical contact adapted to provide electrical continuity with a lower end of a lowermost of said plurality of battery cells;
- (b) a top end cap, said top end cap
- (i) shaped to fit along a portion of said outer surface portion of at least one of said plurality of battery cells, so as to receive therein in snug fitting fashion, transverse cross-sectionwise, at least some of said outer surface of said elongate body portion of said at least one of said plurality of battery cells;
- (ii) further comprising
- (A) a second electrical contact, said second electrical contact adapted to provide electrical continuity with an upper end of an uppermost of said plurality of battery cells;
- (c) an outer surface cover, said outer surface cover comprising a shrink wrap material, said shrink wrap material sized and shaped, when fully treated to its final shrunk size and shape, to compressingly engage and urge said top end cap and said bottom end cap toward each other, so as to compressingly engage battery cells spaced between said top end cap and said bottom end cap.
A battery pack for holding a plurality of battery cells, said battery cells of the shape having an elongate body portion with an elongate body portion with an outer surface portion and opposing first and second ends, each of said first and second ends further comprising either a positive electrical terminal or a negative electrical terminal, said battery pack comprising:

- (ii) further comprising
- (A) a second electrical contact, said second electrical contact adapted to provide electrical continuity to an electrical terminal on said first end of one of said pair of adjacent battery cells, and
- (B) a third electrical contact at the upper reaches thereof, said third electrical contact adapted to provide electrical continuity to an electrical terminal on said second end of one of said pair of adjacent battery cells;
- (c) an outer surface cover, said outer surface cover comprising a shrink wrap material, said shrink wrap material sized and shaped, when fully treated to its final shrunk size and shape, to compressingly engage and urge said top end cap and said bottom end cap toward each other, so as to compressingly engage battery cells spaced between said top end cap and said bottom end cap.
A battery pack for holding a plurality of batteries, said battery pack comprising:
- (a) a first cell holder sleeve body, said first cell holder sleeve body comprising a first tubular segment adapted to receive therein a plurality of elongate battery cells, said plurality of elongate batteries in said first tubular segment having a first lower end battery and a first upper end battery;
- (b) a second cell holder sleeve body, said second cell holder sleeve body comprising a second tubular segment adapted to receive therein a plurality of elongate battery cells, said plurality of elongate batteries in said second tubular segment having a second lower end battery and a second upper end battery;
- (c) a bottom end cap, said bottom end cap
- (i) shaped to fit along a portion of said outer surface of each of a transversely adjacent pair of said battery cells, so as to receive therein in snug fitting fashion, transverse cross-sectionwise, at least some of said outer surface of said elongate body portion of each one of said adjacent pair of said battery cells,
