Abstract
The method comprises the steps of inserting plate lugs in the openings made in the bottom of at least one elementary mould, connecting together the plate lugs by rods formed by melting lead, and making the connection between the rods associated with plates of opposite polarities of two adjacent elements of the accumulator; the said elementary mould comprising a channel common to two adjacent elements of the accumulator. A varied version of an embodiment consists in implementing an elementary mould comprising two channels, each of them having the plate lugs of same polarity fitted in them. The invention is for use in the accumulator industry.
Claims4
A method of constructing a multi-cell storage battery comprising the steps of:
- molding a container of plastic in one piece with outer vertical container walls, an open bottom, longitudinally-spaced transversely extending vertical cell partitions and transversely-spaced parallel channels extending longitudinally across the top of the container from and facing upwardly and outwardly of the container, said parallel channels being partially formed by upright spaced walls, the upper faces of said outer vertical container walls, said spaced upright walls defining said channels and said transversely extending partitions being coplanar, said channels having sections spanning adjacent cells and extending through the cell partition separating said adjacent cells, forming longitudinally-spaced openings within the base of the channels for receiving plate lugs of the same polarity, inserting a plurality of battery plates through the open bottom of said container when said container is in an inverted position with the edges of the plates contacting the undersides of the channel base and with the lugs inserted within respective openings within the base of said channels, sealably coupling an imperforate bottom member to the open bottom of the container to fixedly locate said plates therein, electrically and mechanically coupling the lugs within channel sections together by at least melting said lugs within said channel sections to form strap connectors therein, and thermal welding a lid onto the container top at the coplanar upper faces of the upright walls defining said channels, the container walls, and the longitudinally-spaced paritions to seal the strap connectors within said channel sections.
A multi-cell storage battery comprising:
- a one-piece;
- molded, open-bottom, plastic container including edge joined vertical outer container walls, said container having molded therein longitudinally-spaced, upright cell partitions and transversely-spaced parallel channels partially formed by upright, transversely-spaced walls extending longitudinally across the top of said container from end-to-end and facing upwardly and outwardly of the container, said channels alternately extending through respective cell partitions to form channel sections spanning the cells, the upper faces of said container walls, the vertical upright walls partially defining said cell partitions and said channel walls being coplaner, the base of said channels being provided with longitudinally-spaced openings for receiving plate lugs of the same polarity when a plurality of plates are inserted through the open bottom of said container when the container is in the inverted position with the edges of the plates contacting the undersides of the channel base, an imperforate bottom member sealed to the open bottom of the container to fixedly locate the plates therein, said lugs being melted within said channel section to form strap connectors therebetween and a lid thermoplastically sealed to the coplanar upper faces of said cell partitions, and said walls forming said channels to seal said formed strap connectors within respective channel sections.
