Title: Battery terminal
Inventor: MATSUNAGA HIDEKI
IPC: H01M2/30
Filed: 1995-01-19
Abstract: PURPOSE: To prevent effectively a battery terminal from deforming excessively. CONSTITUTION: A first stopper 18 is formed at the end of one leg piece 6 and a second stopper 19 is formed at the end of the other leg piece 5 while the stoppers sandwich the mounting position of a bolt 11. Restraining projections 20, 21 that restrain the stoppers 18, 19 from slipping on the leg piece 5 or 6 and deforming are provided alongside the abutting positions of the stoppers 18, 19. When an electrode holding portion 2 is reduced in diameter by a predetermined amount because of the tightening of the bolt 11, the stoppers 18, 19 simultaneously abut to the opposite leg pieces 6, 5 to stop the tightening. Since the tightening force is received by the two stoppers 18, 19, the stoppers 18, 19 resist deforming. Should either of the stoppers slip over the leg piece 5 or 6 and tend to deform, it is blocked by the restraining projection 20 or 21 and thus prevented from deforming.
