En conséquence, notamment dans la zone médiane de la barrette de connexion, entre les éléments de fixation, on arrive à un écartement entre la barrette de connexion et la plaque de circuit imprimé et les extrémités libres s'échappent des segments terminaux des perçages associés et des points de raccordement de la plaque de circuit imprimé interdisant toute liaison soudée ou ne permettant qu'une liaison insuffisante. Or, il faut éviter ce risque Consequently, in particular in the central region of the connection strip, between the fastening elements, a distance is reached between the connection strip and the printed circuit board and the free ends escape from the terminal segments of the associated holes and connection points of the printed circuit board preventing any soldered connection or allowing only an insufficient connection. However, this risk must be avoided

Une barrette de connexion 11 est fixée au niveau du bord d'une plaque de circuit imprimé 12. La barrette de connexion 11, selon les figures 1 et 2, comporte un support de contacts 13 en matière isolante électrique. Ce support est muni d'un grand nombre d'éléments de contact 14 répartis en rangées et ces éléments de contact sont logés et noyés dans le support sur une partie de leur longueur. Les éléments de contact 14 ont, d'une part, des segments de contact 16 en porte-à-faux dans un canal de guidage 17 de la barrette de connexion 11, ouvert d'un côté. Ces segments de contact 16 A connection strip 11 is fixed at the edge of a printed circuit board 12. The connection strip 11, according to FIGS. 1 and 2, comprises a contact support 13 made of electrical insulating material. This support is provided with a large number of contact elements 14 distributed in rows and these contact elements are housed and embedded in the support over part of their length. The contact elements 14 have, on the one hand, contact segments 16 cantilevered in a guide channel 17 of the connection strip 11, open on one side. These contact segments 16
