Description

A housing for an electrical device including opposed supports or ribs receiving thereon a circuit board having first and second sides separated by a width "a". A first board support is attached to the housing and has a first side surface, a first support surface substantially perpendicular to the first side surface for supporting the circuit board, and a first recess in the first support surface. A second board support is attached to an opposing side surface of the housing. The side surfaces of the board supports are separated by a distance "b". When distance "a" is greater than distance 'b", the circuit board is retained in an interference fit. Scrapings that are formed during the insertion of the circuit board into the housing can be collected in the support recesses, which provide relief areas, to avoid interfering with the proper seating of the circuit board on the board supports.

L'invention concerne un dispositif électrique, y compris des supports opposés ou des nervures recevant une carte de circuits imprimés ayant deux côtés séparés par une largeur "a". Un premier support de carte est fixé au bâti et a une première surface latérale, une première surface de support substantiellement perpendiculaire à la première surface latérale pour appuyer la carte de circuits imprimés et une première échancrure dans la première surface de support. Un deuxième support de carte est fixé à une surface latérale opposée du bâti. Les surfaces latérales de la carte sont séparées par une distance "b". Lorsque la distance "a" est supérieure à la distance 'b", la carte de circuits imprimés est retenue dans un ajustement serré. Les raclages qui sont formés durant l'insertion de la carte de circuits imprimés dans le bâti peuvent être recueillis dans les échancrures de support, ce qui permet des zones d'allègement, pour éviter l'interférence avec le positionnement approprié de la carte de circuits imprimés sur les supports de carte.
