Electrical apparatus, circuit board and method for detecting a type of housing of an electrical device

摘要

The present invention relates to an electrical device, in particular a computer (1), comprising a housing (2), a printed circuit board (4) comprising at least one fastening device, at least one fastening element which is adapted to connect the printed circuit board (4) via the at least one fastening device to specify on the housing (2), and on the circuit board (4) arranged microcontroller (10). At least one electrical contact (8) electrically connected to the microcontroller (10) is arranged at a predetermined distance (X) from the fastening device on the printed circuit board (4) and the fastening element has a housing-specific diameter at an end facing the printed circuit board (4) ( D, D '). The microcontroller (10) is adapted to determine a type of housing (2) depending on whether the fastener contacts the at least one electrical contact (8). The invention further relates to such a printed circuit board (4) and a method for detecting a type of housing (2) of an electrical device, in particular a computer (1).
