Abstract

Bobina di accensione (B) del tipo "plug-top" comprendente un contenitore isolante (5) a forma di vasca in cui sono disposti un avvolgimento primario (12c) ed un avvolgimento secondario (4a). Gli spazi vuoti nel contenitore (5) sono riempiti con un materiale isolante ivi colato in fase liquida e solidificato. Successivamente il contenitore (5), assemblato con il nucleo magnetico (7), viene completamente rivestito, mediante stampaggio di resina (R). Il costampaggio di resina (R) a bobina (B) completa riduce la rumorosità e la corrosione dei lamierini del nucleo magnetico (7). (Figura 12)Ignition coil (B) of the "plug-top" type comprising an insulating container (5) in the shape of a tank in which a primary winding (12c) and a secondary winding (4a) are arranged. The empty spaces in the container (5) are filled with an insulating material poured therein in the liquid phase and solidified. Subsequently, the container (5), assembled with the magnetic core (7), is completely covered by resin molding (R). Complete co-molding of resin (R) (B) reduces the noise and corrosion of the laminations of the magnetic core (7). (Figure 12)
