Protective arrangement for electronic functional units or groups, e.g. in automobile electronic systems, has screening appropriate to their sensitivity to disturbances

摘要

The arrangement consists of grading the units (A1,A2,CAN,D,S1,S2) to be protected according to their sensitivity to disturbances. The units are then provided with screening (casings) (4,5,8) appropriate to that sensitivity. At least two screens complement one another to form screening with a higher degree of efficiency where units have individual screening and common screening.
