Abstract
An EMI/RFI shielded housing for an electrical apparatus comprises a case member and a complementary cover member, each comprising an end wall portion and a side wall portion together defining substantially continuous and unbroken peripheral surfaces. The side wall portions of these members are respectively configured for an interference fit therebetween to define an assembled condition of the housing. This interference fit is defined by the side wall portion of the case member being received interiorally of the side wall portion of the cover member. Moreover, substantially the entire inner surfaces of the end wall portions of both case and cover member are electrically conductive, substantially the entire inner surface of the side wall portion of the case member is electrically conductive and major fractional portions of respective facing surfaces of the assembled and interference-fitted side wall portions are electrically conductive. All of these conductive surfaces are electrically coupled when the case is assembled to define a continuous shield. However, the exterior surfaces of the end wall portions of both cover and case members, the exterior side wall portions of the cover me…
