摘要:
a chassis assembly that reduces the amount of electromagnetic radiation entering or leaving the interior of the chassis assembly. The chassis assembly includes a chassis cover and chassis back. The chassis cover includes a plurality of dimpled spring contacts and hemmed edges and hemmed lips. The chassis back includes a chassis back top portion adapted to mate with the chassis cover, such that the chassis back top portion is in good contact with the one or more dimpled spring contacts, providing good electrical conductivity. Further, the chassis assembly is designed such that the mating between the chassis cover and chassis back provides a tortuous path to any electromagnetic radiation disposed to enter or leave the chassis assembly.
摘要:
A method of manufacturing a chassis assembly to reduce electromagnetic interference is disclosed. The method includes forming a chassis having a chassis cover top portion, a chassis cover step portion, a chassis cover pre-step portion, a hemmed edge, a hemmed lip, and one or more dimpled spring fingers, by forming a first bend at the hemmed edge residing between the hemmed lip and the chassis cover pre-step portion, forming a second bend between the chassis cover step portion and the chassis cover pre-step portion, and forming a third bend between the chassis cover top portion and the chassis cover step portion. The method further including forming a fourth bends between a chassis back top portion and a chassis back. The formed chassis cover is then seated with the chassis back to create a tortuous path.
