An electronic assembly includes a housing with a plastic part and a metal part. The plastic part includes a mounting lug that mechanically mounts the housing on an external metal support structure. The metal part includes a metal lid and a grounding tab aligned with, or received in a recess of, the mounting lug. Electronic components are grounded onto the metal lid inside the housing, and the grounding tab is electrically connected to the support structure. To isolate mechanical forces and vibrations from the metal lid, a transition part of the grounding tab has a reduced width and/or thickness, and/or includes a bend. The metal lid is received in a recess of the plastic part and is surrounded by a plastic perimeter wall thereof. The plastic part carries the mechanical forces and vibrations, which are substantially isolated from the metal lid. The metal part provides grounding and closes the housing. |
