POST SEAL FOR LEAD ACID BATTERIES

摘要

A terminal post seal arrangement for lead acid batteries is provided which m ay be used both as a moveable post seal or as a static post seal. In a first aspec t of the subject invention, a battery is provided with an elastomeric sealing member rigidly fixed to both the cover of the battery and a bushing about a terminal post. Preferably, the sealing member includes a slack portion between its rigid connections which allows for relative movement between the bushing and the cover. In a second aspect of the subject invention, a collar is formed in the cover to bound the terminal post. The collar and/or the sealin g member are formed at least partially tapered such that relative movement between the collar an d the sealing member causes interferent engagement. It is preferred that interference between the collar and the sealing member become greater with increasing extent of relative movement.
