Abstract
A voltage tap apparatus functions as both a voltage tap and a cell isolator for conductive case battery cells that are joined end-to-end in a series chain. The apparatus includes conductive leadframe elements partially encased in a plastic frame that engages the joined cells about their juncture, with portions of the lead-frame elements exposed to electrically contact the conductive cases of the cells. In a first embodiment, the plastic frame is in the form of a hinged clamp that closes about the juncture of the cells, and the lead-frame elements are routed to terminals formed on one end of the frame. In a second embodiment, the plastic frame and a connector are mounted on a printed circuit board and the leadframe elements in the plastic frame couple the battery cells to the connector.
