Abstract

This invention relates to an ignition coil for the engine of a vehicle. The ignition coil comprises a core member (18) having a number of layers wrapped around it. The formation of these layers from the core member outward comprises a secondary support spool (22), a secondary coil (24), a primary support spool (28) and a primary coil (32). Resilient thermal expansion de-coupling means (30) is provided between at least one of the primary and secondary coils (32, 24) and its or their corresponding support spool or spools (28, 22). The thermal expansion de-coupling means (30) allows each layer to expand and contract substantially independently of one another. This reduces the stress exerted on each layer as it is heated/cooled which increases the overall lifetime of the ignition coil.
