Piezo actuator module with a cladded piezo actuator

摘要

The module has a piezo actuator (20) mounted between an actuator head and an actuator base. A casing enclosing the piezo actuator for electrical passivation is an insulation protective layer (25). The casing is attached to connection units (21, 22) by mechanical connection in a region of front surfaces of the piezo actuator and/or actuator head and/or the actuator base in a force fit and/or form fit manner.
