Abstract
An electrode is provided with a metal terminal extending from a battery module main body, a bolt which has an expanded section configuring a retaining section at a rear end portion and penetrates the metal terminal upward, and an insulating body which insulates the metal terminal and the battery module case one from the other. The insulating body is provided with a drop preventing section which abuts at least a lower surface of the expanded section of the bolt and prevents the bolt from dropping from the metal terminal.
Claims5
A battery module connected by a bus bar, comprising:
- a metal terminal extending from a body of the battery module and connected to said bus bar;
- a rivet electrically connecting said metal terminal to a battery cell housed in a case of the battery module;
- and
- an insulator insulating said metal terminal and the case from each other,
- said metal terminal including a fixing piece fixes the case, said fixing piece having a through hole, and
- said insulator having a peripheral wall covering an outer periphery of said fixing piece,
- wherein said rivet passes through said through hole and said insulator, and fixes the fixing piece to the case, and wherein the insulator is retained between the fixing piece and an outer surface of the case.
