The invention relates to an attachable rod ignition coil comprising an ignition coil part and an adapter provided with an ignition plug receiving element for fixing the adapter to an ignition plug. A shock-absorbing element is arranged between the ignition coil part and the adapter and/or between the adapter and the ignition plug receiving element.

Attachable rod ignition coil

The winding () of an ignition coil device () is to be better sealed in order to afford it more protection from fouling, moisture, and reagents of all kinds. Provision is accordingly made such that there is introduced between a winding element () and an outer metal jacket () a rubber insulating element () having a sealing profile (). As a result, improved sealing from the winding element () and the outer metal jacket () is provided. As an alternative, provision may be made such that the insulating element () including a sealing compound () is introduced between the outer metal jacket () and the winding element ().
