Explosion-proof electrical equipment with molded housing

摘要

An electric appliance comprises a component part (101) that comprises electronic components, among which is an electrolytic capacitor (105). A moulded part (301) is moulded around the component part (101), An outer surface of the moulded part (301) constitutes at least a part of the outer surface of the electric appliance. The moulded part comprises a cavity (302), which contains something else than electronic components or connections between electronic components. The cavity (302) is separated from the electrolytic capacitor (105) by at most a wall the thickness of which is smaller than a mean material thickness of the moulded part (301) between the component part (101) and outside of the electric appliance.
