Gas and liquid tight pole seal for electric storage batteries, particularly lead storage batteries
Patent
·
OSTI ID:6473148
A hermetic pole seal for lead storage batteries which averts the customary use of lead sleeves, involves a first ring-shaped molding surrounding the pole shaft with a rubber-elastic synthetic plastic (thermoplastic rubber) and a second molding covering the former with a less elastic synthetic, which is preferably identical to the case material (e.g. polypropylene), followed by mirror welding to the lid. The sealing of the pole lead-through results from material shrinkage following the molding. In so doing, the different plastics mesh from opposite sides.
