Electric storage battery and a method of making the same
First Claim
1. An electric storage battery comprising a battery case having partition walls provided to form compartments therein, cell components disposed within the respective compartments and each including a plurality of positive and negative plates alternately arranged with insulating separators disposed between the adjacent positive and negative plates, and connectors provided between the adjacent cell components for electrically connecting them, characterized by each of said connectors comprising;
- first plate lugs of said positive plates for one of said adjacent cell components;
second plate lugs of said negative plates for the other cell component;
said first and second plate lugs facing each other through the corresponding partition wall of said battery case;
and a welded portion of said first and second plate lugs being deformed to be gathered together;
all said plate lugs being unitary with and of substantially the same thickness as the respective plates, said welded portion being the gathered-together group of first plate lugs on one side of a partition wall and the gathered-together group of second plate lugs on the other side of the partition wall with a portion of each of the proximate one of said first and second plate lugs deformed toward each other to be in mutual contact and welded together.

Abstract
This invention pertains to an electric storage battery and more particularly to a connector for electrically connecting adjacent cells of the electric storage battery with each other.
The electric storage battery comprises a battery case having partition walls provided to form compartments therein, cell components disposed within the respective compartments and including a plurality of positive and negative plates alternately arranged with insulating separators disposed between the adjacent positive and negative plates, and connectors provided between the adjacent cell components for electrically connecting them. Each of the connectors comprises first plate lugs of the positive plates for one of the adjacent cell components and second plate lugs of the negative plates for the other of the adjacent cell components, the first and second plate lugs facing each other through the corresponding partition wall of the battery case and being deformed to be gathered together and being welded integrally with each other. The first and second plate lugs may be welded through an opening in the corresponding partiton wall. Otherwise, the first and second plate lugs may be welded at the top of the corresponding partition wall of the battery case.
