The invention relates to a fixing system for printed circuit boards (2, 3) arranged one above the other in an electronics housing, in particular for the automotive sector. The invention provides that a printed circuit board (2) is fixed to the electronics housing by a rigid fixing means (6) and all of the other printed circuit boards (3) are fixed by means of sprung fixing means (7). The present invention firstly advantageously provides a fixing system for printed circuit boards (2, 3) arranged one above the other in an electronics housing which makes it possible for the printed circuit boards (2, 3) to be mounted in a stress-free manner, but in the process forms defined thermal transition regions, and which requires little installation space on the printed circuit board (2, 3). It is particularly suitable for the automotive sector.
L'invention concerne un système de fixation conçu pour des cartes de circuits imprimés (2, 3) superposées dans un boîtier électronique, en particulier pour le domaine automobile. Selon l'invention, une carte de circuits imprimés (2) est fixée sur le boîtier électronique par l'intermédiaire d'un moyen de fixation rigide (6), et toutes les autres cartes de circuits imprimés (3) sont fixées par l'intermédiaire de moyens de fixation à ressort (7). De manière avantageuse, ce système de fixation pour cartes de circuits imprimés (2, 3) permet de monter les cartes de circuits imprimés (2, 3) sans application de tension, tout en créant des zones de transfert thermique définies, l'espace de montage requis sur les cartes de circuits imprimés (2, 3) étant faible. Ce système de fixation convient en particulier pour le domaine automobile.
