ABSTRACT:
The invention relates to a shielding device in a transitional area between a housing (1,11) and a cable (3), wherein the housing (1,10,11) consists of an electrically insulating and/or electromagnetically insufficiently shielding material, an inner housing (12) with an electrically conductive material for forming an electromagnetic shielding for its inner chamber is arranged inside the housing (1,11,10), the cable (3) is designed with at least one line (30) and a cable shielding (31) for forming an electromagnetic shielding for the at least one line, and a cable connection device (4) is arranged for connecting the cable to the inner housing and for connecting the at least one line to a line connection device (18) on the inner housing in the transitional area.It is suggested for forming a continuous shielding even in the translational area that the cable shielding (31) be brought in contact with an electrically conductive spring stop (46) on the cable side, and that a spring be brought in contact via the cable-side spring stop (46) with an electrically conductive housing-side spring stop (48) with the inner housing (12).
