Abstract
An ignition plug cap having at least a plug cap terminal and a discharge tube as a series gap at one end of a high-tension cord for providing electric high-voltage pulses to an ignition plug in a vehicle, wherein the ignition plug cap further comprises an electrically insulating casing for accommodating the plug cap terminal and the discharge tube, which is formed with heat dissipating means such as a plurality of fins formed on the external surface thereof either in parallel or at right angles with vertical axis of the electrically insulating casing, or they can be simultaneously formed otherwise, apart from a spiral fin and so on. With this construction, heat generated therein is effectively dissipated for controlling a rise of temperature, whereby the components of the ignition plug cap in general will not be readily deteriorated even in long-term severe driving conditions.
