Patent ID: 8344839

Claim:
A transformer including: a coil former comprising: a plurality of windings wound on the coil former, at least one first insulating flange separating a first winding of said plurality of windings from at least one second winding of said plurality of windings, at least one second insulating flange defining together with said at least one first insulating flange a winding space for said at least one second winding, wherein said first winding has at least one end extending across said winding space for said at least one second winding, wherein said at least one first insulating flange is an integral part of said coil former, and a protective cap comprising: an insulating material, lateral walls, a skirt wall extending outwardly of said lateral walls, an insulating wall extending downwardly from the skirt wall and extending radially from the lateral walls, said insulating wall is an integral part of said cap, wherein the protective cap is coupled with said coil former after the winding to at least partially cover said plurality of windings, and said protective cap having at least one extension cooperating with said at least one first insulating flange to provide insulation between said first winding and said at least one second winding opposite said insulating wall, said insulating wall extending between said at least one end of said first winding extending across said winding space for said at least one second winding and said at least one second winding to provide insulation therebetween.
