Coil assembly, especially for the ignition of an internal combustion engine has a cast mass to fix the coil and an elastic mass to bond the coil to the core, giving compensation for expansion

摘要

The electronic component group has at least one coil (1) e.g. for the ignition of an internal combustion engine, and a core (2). The coil is fixed in place by a cast mass (6) and is bonded to the core by an elastic mass (5). The coil structure has a primary (4) and a secondary (3) coil, formed by copper wires (3.2, 4.2) wound around carrier bodies (3.1, 4.1). The coils are of different diameters for one to fit within the other.
