Abstract
The present invention refers to a heating plug, more particularly, a heating plug containing an exposed filament, which is used in fuel galleries, principally those applied in internal combustion engines requiring fuel heating. The heating plug with exposed filament provided with an insert, said heating plug including a shell (10), which encloses, inside, at least one electrical terminal (20); at least one filament support (60); and at least one filament (70) in electrical contact with said at least one electrical terminal (20) by means of at least one pin (50). The present invention provides a sufficiently robust, efficient and reliable solution which does not demand altering all the constructive arrangement of the heating plug, which is capable of assuring adequate sealing between the fuel gallery and the heating plug and which, moreover, guarantees the correct power supply to the exposed filament.
