Abstract
A protection device for an electrical component that has a protective housing and a terminal cap. The protective housing has a base with a contact hole therethrough for accommodating an electrical terminal pin. A projecting perimeter wall extends from the base. Attached to the perimeter wall is an inwardly extending tapered rib. Each rib is tapered such that the end of each rib closest to the base surface extends from the perimeter wall further than the end of the rib furthest from the base surface. A terminal cap is placed within the perimeter wall and forced toward the base surface until the tapered ribs engage and are deformed by the terminal cap to provide an interference fit between the ribs and the terminal cap. A method of assembling a battery and an electrical component with such a protection device is also disclosed.
