Gas- och vätsketät poltätning för el- ackumulatorer, särskilt blyackum ulatorer samt förfarande för framställning av tätningen. |
摘要 |
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. |
