ABSTRACT:
A combination instrument for automotive vehicles, in which different indicating instruments, indicating fields, control and warning lights, and, possibly, operating parts as well as electrical and electronic equipment parts, are arranged in common housing. The combination instrument comprises a computer unit with microcomputers (36) and/or use-specific integrated circuits which are arranged, for protection against electromagnetic disturbances, within a housing (31) which is impervious to high frequencies. Furthermore, disturbance-endangered incomiing and outgoing lines (41, 43, 46) are protected, upon entrance or exit, by suitable filter measures. These include leadthroughs with leadthrough capacitors (45) and the use of ferrite cores (47, 48) through which connecting lines are extended. For shielding against disturbing radiation and for obtaining a low profile of installation, in one embodiment, a lower part (38) of a multiple-plug-type connector is fastened on a least one outer surface of the high-frequency-proof housing, and electrical contacts are formed by elongated conductors (32) which extend in a single piece from a circuit board (33) through a housing wall (34) into the plug-type connector.
