Abstract
Previously known circuit boards as components of devices having a housing have a plastic rear wall of the housing and the circuit board creates a connection between at least two printed circuit boards in the housing. Furthermore, processes for the production of three-dimensional printed circuits are known. Taking these as a point of departure, a one-piece circuit board as an integral portion of the housing of the device is created. One that not only produces the function of an electrically-conductive connection between the aforementioned printed circuit boards, but also serves as a mounting for the printed circuit boards, i.e., it can assume mechanical functions. This is solved by virtue of the fact that the rear wall (1) of the housing consists of plastic and embodies a circuit board having metallized strip conductors (2) and flat surfaces (3) that conduct electricity. And, on the interior of the rear wall (1), protruding connectors are moulded. The latter are themselves metallized, and they are, by dint of the strip conductors (2) and/or the flat surfaces (3), connected with one another so as to conduct electricity. The printed circuit boards ( 5) may be connected electrically to the connective media (4). Such circuit boards may be used in devices that provide automation.
