CONNECTION STRUCTURE FOR ELECTRICAL STORAGE ELEMENT GROUPS

摘要

A connection structure (10) is provided for connecting electrical storage element groups (12), each of which is formed by connecting electrical storage elements (13) having electrode terminals (14) in series, side by side. The electrical storage element groups (12) are connected electrically by connecting a connecting member (20) for connecting adjacent electrical storage element groups (12) to a first electrode terminal (16A) and a second electrode terminal (16B). The first electrode terminal (16A) is arranged on one end part of one electrical storage element group (12) and on the side of the adjacent other electrical storage element group (12) and the second electrode terminal (16B) is the electrode terminal (14) arranged on another end part of the other electrical storage element group (12B) opposite to the one end part of the one electrical storage element group (12A) and on the side of the adjacent one electrical storage element group (12A).

1. A connection structure for electrical storage element groups for connecting a plurality of electrical storage element groups side by side, each electrical storage element group being formed by connecting a plurality of electrical storage elements each having positive and negative electrode terminals on the same surface in series, wherein:
the plurality of electrical storage element groups are electrically connected by connecting a connecting member for connecting adjacent ones of the electrical storage element groups to a first electrode terminal and a second electrode terminal, the first electrode terminal being the electrode terminal arranged on one end part of one electrical storage element group and on the side of the adjacent other electrical storage element group and the second electrode terminal being the electrode terminal arranged on another end part of the other electrical storage element group opposite to the one end part of the one electrical storage element group and on the side of the adjacent one electrical storage element group; the connecting member includes two terminal connecting portions to be respectively connected to the first and second electrode terminals and a linkin-g-pectia4 linking the two terminal connecting portions, whereas the holding portion of the insulation protector includes a protection wall arranged along a peripheral edge of the connecting member; the arrangement direction of the electrical storage elements and that of the electrical storage element groups are orthogonal and the linkin-g-pectia4 is arranged in a direction oblique to the arrangement direction of the electrical storage elements and that of the electrical storage element groups; and a clearance is provided between the link of the connecting member and the protection wall in the arrangement direction of the electrical storage elements and that of the electrical storage element groups.
