VERBINDUNGS- UND SCHALTUNGSANORDNUNG.

摘要

The printed circuit board assembly (10) comprises a base (16), PCB (17), components (12-15), and connections (20). Several such assemblies are mounted on a carrier (30). The carrier comprises two plates (26,27), separated by a spacer (28) to provide cooling channels between the plates. The carrier also has printed circuit boards (21,23), one on each side, with conductors in a pattern to match the modular assembly (10) terminal pattern (20). The boards (21,23) on the carrier (30) have openings which match the outline of the modular assemblies. The modular assemblies are held down on the carriers with screws and also spring inserts to give good electrical contact at the connections (20;21,23), and good thermal contact between base (16) and the carrier (30;27,26).
