Packed batteries and method of making the same
First Claim
1. A packed battery comprising:
- (a) a power generating element including a plurality of cylindrical cells disposed side-by-side and electrically connected in series by a conductive connector, and an adhesive-backed labeling sheet member wrapped around the peripheries of the respective cylindrical cells;
(b) a frame holding therein said power generating element and composed of a pair of generally I-shaped frame members molded of synthetic resin and joined together to define therebetween a substantially hollow space with one end open for receiving therein said power generating element, and an end cap molded of synthetic resin and joined with said frame members to close said open end; and
(c) a pair of terminals attached to one of said frame members, each said terminal having one end connected to one of two terminal ends of said power generating element, the other end of said terminal being exposed to the outside of said frame for permitting electric current to be drawn from the power generating element.

Abstract
A packed battery includes a frame composed of a pair of substantially I-shaped frame members molded of synthetic resin and joined together to hold therein a power generating elements composed of a plurality of series-connected cells, and an end cap molded of synthetic resin and joined with the frame to close an open end of the frame. One of the frame members has in its one end face a pair of apertures through which a pair of external terminals is inserted for connection to positive and negative terminal end faces of the power generating element. With this construction, the packed battery has a high capacity per unit volume and the external terminals and the positive and negative terminal end faces can be welded easily and efficiently. Accordingly, the packed battery can be manufactured at a high rate of production.

8. A method of making a packed battery including a power generating element having a plurality of cylindrical cells disposed side-by-side and electrically connected in series by a conductive connector, and an adhesive-backed labeling sheet member wrapped around the peripheries of the respective cylindrical cells, a frame holding therein the power generating element and composed of a pair of generally I-shaped frame members molded of synthetic resin and joined together to define therebetween a substantially hollow space with one end open for receiving therein the power generating element, and end cap molded of synthetic resin and joined with the frame members to close the open end, and a pair of terminals attached to one of the frame members, each of the terminals having one end connected to one of two terminal ends of the power generating element, the other end of the terminal being exposed to the outside of th frame for permitting electric current to be drawn from the power generating element, said method comprising the steps of:
-
(a) bonding with an adhesive a plurality of cylindrical cells together in side-by-side; (b) electrically connecting the cylindrical cells in series by a conductive connector; (c) wrapping the cylindrical cells on their peripheries with an adhesive-backed labeling sheet member, thereby completing a power generating element; (d) holding the power generating element between a pair of generally I-shaped frame members molded of synthetic resin and ultrasonically fusing the two frame members together to thereby join them with the power generating element firmly held in a frame composed of the thus-joined frame members; (e) attaching a pair of terminals of a generally 7 shaped configuration to one of the frame members by first inserting respective one end portions of the terminals into the one frame member through apertures defined in the one frame member until the one end portions engage two terminal end faces of the power generating element and respective other end portions of the terminals are fitted in retainer recesses in the one frame, then welding the one end portions of the terminals to the terminal end faces of the power generating element to thereby connect the terminals and the power generating element; and (f) fitting an end cap molded of synthetic resin into an open end of the frame to close the same with the opposite end portions of the terminals firmly gripped by and between the end cap and the one frame member of the frame, then ultrasonically fusing the end cap and the frame members to thereby join them integrally. - View Dependent Claims (9)
