Abstract
Abstract A multi compartment electromagnetic energy shield (100) arranged for assembly to a mounting surface (203) of a carrier (201), the multi compartment electromagnetic energy shield includes an enclosure (101) and a partition (103) having electromagnetic shielding properties. The enclosure includes a first surface (405) and a first and a second side wall (105, 107) each extending from the first surface (405) to the mounting surface (203) of the carrier (201) after the assembly to the mounting surface of the carrier. The partition (103)including a mounting edge (305) and being arranged and constructed to electromagnetically divide the enclosure into multiple compartments (111, 113). The partition further captivated by the first and the second side wall (105, 107) in a free floating manner such that the mounting edge coincides with the mounting surface (203) after assembly to the mounting surface of the carrier (201).
