Abstract

Montage ou support de cristal piézo-électrique rectangulaire revêtu d'une électrode sur chaque face (résonateur à quartz), constitué par deux lames métalliques fendues pliées symétriquement par rapport au centre du cristal. Selon l'invention, les quatre coins du cristal 1 sont tronqués et des languettes résultant de la découpe des fentes dans les lames de support 6, 7 s'appuient élastiquement sur ces coins. Les deux languettes 9, Il et 8, 10) de chaque lame sont rabattues en sens opposé, de sorte que chaque languette supérieure collabore avec la languette inférieure de l'autre lame pour fournir une pression supplémentaire en diagonale. Les lames sont conductrices et relient les bandes de connexion 4, 5 des électrodes 3 aux broches de sortie 12, 13 de l'oscillateur. Application aux générateurs de fréquence pour horloges et montres électroniques.
