Abstract
In the housing of a battery there is a circular opening to which is fixed an outwardly extending cylindrical metal sleeve. A tubular ceramic insulator having high compressive strength and provided with an axial passageway as well as first and second tapered ends has one of those ends resting in the first cylindrical metal sleeve. A second cylindrical metal sleeve similar to the first rests on the other end of the tubular ceramic member. The second sleeve is provided with a cap through which passes an electrical conductor. The conductor extends through the passageway of the ceramic member into the battery housing. An axially compressive force rams the metal sleeves fixedly to the tubular ceramic insulator.
