Electronic unit with a PCB and two housing parts
First Claim
1. An electronic unit comprising:
- a circuit board, arranged to be mounted in a main housing, which main housing having a first housing part and a second housing part,the circuit board having a first outer layer, a second outer layer, and an internal ground plane, where the outer layers are separated from the internal ground plane by at least a dielectric material,where the first outer layer faces the first housing part and the second outer layer faces the second housing part,wherein the ground plane is arranged to make electrical contact with the first housing part such that a first chamber facing the first outer layer, and a second chamber, facing the second outer layer, are formed,where the first and second chambers are separated by means of the ground plane, such that an electromagnetic shielding is created between the first and second chambers, anda connector arranged for establishing electrical contact between the electronic unit and parts outside the electronic unit, the connector having a number of connector pins and at least partly being positioned in the second chamber.

Abstract
An electronic unit (1) having a circuit board, PCB, (2) arranged to be mounted in a main housing (6, 7 and having a first housing part (6) and a second housing part (7), where the first housing part (6) is at least partly electrically conducting. The PCB (2) having a first outer layer (3), a second outer layer (4), and a ground plane (5). The first outer layer (3) faces the first housing part (6) and the second outer layer (4) faces the second housing part (7) The ground plane (5) is in electrical contact with the first housing part (6) forming a first chamber (29), facing the first outer layer (3), and a second chamber (30), facing the second outer layer (4). The chambers (29, 30) are separated by the ground plane (5), providing electromagnetic shielding between the chambers (29, 30).
