Abstract

The compartmented former, for high voltage winding used as an internal combustion engine ignition coil, has high electrical insulation, is compact and can, to a large extent, be manufactured automatically. The compartment walls are distributed axially along the former and the separate coils are connected in series by wires passing through slots between compartments. Each interconnecting slot (17) is located inside the wall (18) that separates two adjacent compartments containing coils. Each slot is masked on both sides from both adjacent compartments by a wall (19).
