Terminal apparatus for electrolytic device

摘要

Terminal structure is disclosed for use in electrolytic devices such as batteries, in which a deformable, electrically conductive material (14) is caused to seal around an opening (26) in a container (10, 12) of resilient material by means of a fastener (24, 30) which extends through the opening into the electrically conductive material and a wedging element such as a chamfered surface (34) associated with the fastener which compresses the resilient material surrounding the opening. A method of assembling such a terminal structure is also disclosed.
