A housing for an electronic component

A housing 70 for an electronic component comprises snap-fit features 72 to retain an electronic component in the housing 70 and spring means 76 to bias the component into contact with the snap-fit features 72. The component may include a laminated magnetic core in which the stack of laminations are pressed together by the spring means 76. The electronic component may be inserted in an opening in the housing such that certain features of the component interact with the snap-fit features of the housing to retain the component in the housing. The housing 70 and the snap-fit features 72 may be formed from moulded plastic in which the snap-fit features 72 are projecting resilient lugs. The electronic component may be a transformer comprising coils, a bobbin and a laminated core. The housing 70 may include openings to allow fluid to flow through the housing. The wall thickness and opening dimensions of the housing 70 may be arranged to meet the creepage and clearance distances and insulation requirements of the transformer.
