Abstract
In a module having an electrical component, which is situated between two ground planes for electromagnetic shielding, a trough-shaped composite component is provided between an inner and an outer housing, into which the rear side of the inner housing is inserted, the composite component having an insulator trough and, on its inside, a ground plane formed at least on the trough bottom, which forms the shielding of a rear side of the electrical component. The composite component is advantageously designed as an MID component. The outer housing of the module may be manufactured in the two-component injection molding process by extrusion-coating initially using an elastomer and subsequently a thermoplast.
Claims9
A module having an electrical component, comprising:
- an inner housing which surrounds the electrical component and has a front side and a rear side;
- an outer housing in whose interior the inner housing is situated;
- first and second ground planes to electromagnetically shield the electrical component, which are situated opposite each other, the electrical component being situated between the first and second ground planes;
- and
- a trough-shaped composite component situated between the inner housing and the outer housing, into which the rear side of the inner housing is inserted, the composite component having an insulator trough and, on its inside, a ground plane formed at least on a bottom of the insulator trough, which forms the shielding of a rear side of the electrical component.
