ENCAPSULATING ARRANGEMENT FOR AN ELECTRICAL COMPONENT

摘要

The invention provides an encapsulating arrangement (30) for an electrical component comprising first and second insulating layers (32, 36) and an electrically charged conductive layer (34), preferably in the form of a metal foil, intermediate the first and second insulating layers (32, 36), and arranged to prevent the passage of ionic species across the encapsulating arrangement (30). The encapsulating arrangement (30) of the invention has particular application to piezoelectric actuator arrangements for fuel injectors of internal combustion engines.
