ABSTRACT:
A self-sealing battery terminal including a hydroformed Inconel outer case, a low shear strength sealant material, and a central post in the form of a bolt which acts as both a conductor and transmits the preload from a pair of Belleville washers to a lower ceramic washer. The lower ceramic washer acts like a piston to compress the sealant when the nut on the central post is tightened. The Belleville washers serve to maintain a minimum tension on the central post. A top ceramic washer is held in place by the tension in the central bolt as long as the tension exceeds a minimum value.
