    Abstract: The interface between the plastic cover of a battery container and the lead or other metal terminal post which extends therethrough is sealed with a rubber bushing which is compressed and extruded along the terminal post during installation and locked tightly in its compressed and extruded state. The bushing preferably has a pair of oppositely angled intersecting frustoconical surfaces on its exterior surface which are adapted to cooperate with mating surfaces surrounding the opening in the cover and on a locking retainer. The assembly provides a flexible seal which will accommodate the inevitable vertical movement of the terminal post as a result of battery element expansion. Most importantly, the assembly provides an extremely effective barrier to the migration of electrolyte along the terminal post to prevent outer terminal corrosion. The rubber bushing is preferably impregnated with silicone oil which, when the bushing is installed, fills the surface voids in the cast terminal post which otherwise provide paths for electrolyte migration. The silicone oil also provides a lubricant for the controlled compression and extrusion of the bushing.

    Abstract translation: 电池容器的塑料盖和延伸穿过其的导线或其他金属端子柱之间的界面用橡胶衬套密封，橡胶衬套在安装期间沿着端子柱压缩和挤出并且紧密地锁定在其压缩和挤压状态。 套管优选地在其外表面上具有一对相对角度的相交的截头圆锥形表面，其适于与围绕盖中的开口的配合表面和锁定保持器协作。 组件提供了柔性密封，其将适应由于电池元件膨胀而导致的端子柱的不可避免的垂直运动。 最重要的是，该组件为电极沿着端子柱的迁移提供了非常有效的屏障，以防止外部端子腐蚀。 橡胶衬套优选地浸渍有硅油，当安装衬套时，填充铸造端子柱中的表面空隙，否则其提供用于电解质迁移的路径。 硅油还提供润滑剂用于受控压缩和挤压衬套。

    Abstract: A vent cap for use in a recombinant battery which includes a hollow barrel configured for gas-tight insertion into a vent hole in a battery cover. A retaining flange is formed at the closed end of the barrel, and a one-way relief valve formed on the barrel near its closed end. A layer of a polyalkylene explosion attenuating material surrounds the outside of the barrel below the flange and surrounding the relief valve. The polyalkylene material provides effective attenuation of explosions that occur in the vicinity of the relief valve. The invention further provides a vent cap assembly wherein the foregoing vent cap is mounted on a plastic vent cover of an otherwise conventional battery container.
