Battery holding frame and assembled battery

摘要

An insulative battery holding frame for holding a battery cell includes a fixing portion for fixing the frame to a base member, and an electrical connection preventing portion for preventing any electrical connection between the base member and the fixing portion, the connection being caused by flow of a fluid. The electrical connection preventing portion can include an entrance preventing portion for preventing the fluid having electrical conductivity from entering into the fixing portion, and a guiding portion for guiding the fluid into an insulation region arranged in a lower side portion of the secondary battery cell.

1. An insulative battery holding frame for holding a secondary battery cell including an electrolyte, the frame comprising:
a frame portion having inside thereof a battery holding portion for holding the secondary battery, the frame portion comprising a lower frame portion and side frame portions; a projection portion formed by a bottom portion of the lower frame portion that projects toward a lateral direction from an outer wall of each of the side frame portions of the frame portion; a fixing portion provided on the projection portion, for fixing the frame to a base member; and an electrical connection preventing plate for preventing any electrical connection between the base member and the secondary battery cell, the connection being caused by flow of a fluid having electrical conductivity, wherein the electrical connection preventing plate comprises: an entrance preventing portion disposed between a side wall of the holding frame and the fixing portion so as to project from an upper surface of the projecting portion, for preventing the fluid having the electrical conductivity from entering into the fixing portion; and a guiding portion projecting from a side surface of the projecting portion for guiding the fluid into an insulation region arranged in a lower side portion of the secondary battery cell.
