Bellis, L; Prokopp, R

The sealed feed-through interconnects two cells of an alkaline storage battery (eg. for an electrically propelled car) by passing through a wall of the battery. The battery includes a monobloc casing of plastic material defining at least two battery cell compartments which are separated by said wall, and said wall has an orifice for receiving the feed-through. The feed-through comprises a first portion for electrical connection to electrodes of a first polarity in a first one of the cells and a second portion for electrical connection to electrodes of opposite polarity in the other cell. In an alkaline battery, conventional welding techniques for making such feed-throughs in lead-acid batteries are not applicable because metals such as nickel steel must be used instead of lead. The resulting welding temperature would destroy the plastic wall. Instead, the first and second portions include interfitting male and female portions suitable for passing through said orifice from opposite sides thereof and for engaging each other in a force fit. Respective skirts surround said interfitting portions and serve to compress at least one deformable sealing member around the orifice. Stops are provided to prevent the wall being crushed when the feed-through portions are forced together.
