US 8,785,028 B1 · High conductivity battery contact

Abstract

A high conductivity battery contact that comprises: a printed circuit board, a compressive spring, a tab containing thin, flat and highly electrically conductive metal. Said tab has three sections: a mounting section connected to said printed circuit board, a flexible intermediate section and a contact section with an outward facing surface roughly parallel with said circuit board. These parts form a layered assembly with said compressive spring positioned between the tab contact section and the printed circuit board. When a cylindrical battery cell is placed into position, the tab contact section is pressed into contact against an end of said cylindrical battery cell by said compressive spring.
