Abstract:
A contact structure in an electromagnetic shielding, by which the interior of a housing is electromagnetically shielded from the outside,said housing having walls, at least one opening in one of said walls and a closing element adapted to optionally open and close said opening, said housing and said closing element each having an electrically conductive shielding layer, said contact structure serving to establish electric contact between the shielding layers of said housing and said closing element, said housing representing a first part, and said closing element representing a second part, said contact structure comprising electric contact means at one of said parts conductively connected to said conductive layer of said part, said contact means, when said opening is closed by said closing element, extending around said opening for establishing electric contact between said conductive layer of said one part with said conductive layer of the other one of said parts, wherein said one of said parts has a circumferential groove in an end face around said opening, said groove having inwardly projecting longitudinal ledges, whereby a circumferential cavity is defined by said groove and said ledges, said cavity being open through a slot between said ledges, said ledges being recessed at, at least, one location along said slot to define an opening wider than said slot to permit insertion of said contact means therethrough, said contact means having side portions which, after such insertion and longitudinal displacement in said cavity, are held in place by said ledges.
