Electrical appliance based on circuit board technology, has modules electrically connected to one another via bus

摘要

An electrical device has several modules inserted in a housing and comprise circuit boards equipped with electrical components, in which the modules are electrically joined to one another via a bus and can be contacted externally via terminals fixed in the region of the rear face of the housing. The bus is designed as at least one bus circuit board (8) with conductor strips (10), which are arranged on the upper- and lower-surfaces of the housing and strip-form pluggable connectors (9) are fixed on the bus circuit board and into which the circuit boards of the modules can be inserted.
