Title:
TERMINAL CONNECTING METHOD FOR ELECTRODE PLATE OF STORAGE BATTERY
Document Type and Number:
Japanese Patent JPH04112453
Kind Code:
A
Abstract:

PURPOSE: To connect a terminal plate with an electrode plate strongly by bending part of the terminal plate, and fitting in a through penetrative part provided in the electrode plate.

CONSTITUTION: An electrode plate 1 and a terminal plate 2 are put one over another between a lower die 7 and an upper die 5 having a pin 4 of triangular cross-section, and the two dies 5, 7 are moved to permit the pin 4 to penetrate the terminal plate 2 and electrode plate 1. Therein a clearance of a size approx. equal to the thickness of the terminal plate is provided between one edge of a triangular section hole 6 in the lower die 7 and one edge of the pin 4, and thereby one side of the triangle of terminal plate 2 is not severed but bent at a bending part 9. Then the terminal plate 2 is pressed by a pressing plate 8, and a protrusion part 10 protruding at the undersurface of the electrode plate 1 while bent at the bending part 9 is pushed wide by a pawl 11 and put in pressure contact with the undersurface of the electrode plate.
