Abstract[English]
A clinch fastener has material displacing features which create a lengthened leak path boundary between the fastener and an attached panel which can be a potential leak path of fluid from one side of the panel to the other. The material displacing features include a dimpled peripheral rim which displaces material of the attached panel along the perimeter of the fastener and lengthens the leak path. An increased installation pressing speed using these structures creates trapped compressed pockets of air above atmospheric pressure between the fastener and the panel providing additional leak resistance.[French]
Un élément de fixation de rivet présente des éléments de déplacement de matériau qui créent une limite de trajet de fuite allongée entre l'élément de fixation et un panneau fixé qui peut être un trajet de fuite potentiel de fluide d'un côté du panneau à l'autre. Les éléments de déplacement de matériau comprennent un rebord périphérique en creux qui déplace le matériau du panneau fixé le long du périmètre de l'élément de fixation et allonge le trajet de fuite. Une vitesse de pression d'installation accrue à l'aide de ces structures crée des poches comprimées piégées d'air au-dessus de la pression atmosphérique entre l'élément de fixation et le panneau fournissant une résistance aux fuites supplémentaire.
