The invention relates to an electromechanical converter comprising at least one piezoelectric element (1, 13, 33) having a first surface carrying a first electrode (3, 15, 17), and at least one contact lug (5, 29, 31) by which means the piezoelectric element (1, 13, 33) is electrically connected. According to the invention, the electrical connection of the piezoelectric element (1, 13, 33) has very high contact stability, as the contact lug (5, 29, 31) is directly adjacent to the first electrode (3, 15, 17) and comprises at least one recess (7, 25, 27, 39) in which an adhesive (9) is placed, said adhesive connecting the contact lug (5, 29, 31) to the electrodes (3, 15, 17).
L'invention concerne un convertisseur électromécanique comprenant au moins un élément piézo-électrique (1, 13, 33), doté d'une première surface portant une première électrode (3, 15, 17), et au moins une languette de contact (5, 29, 31) pour le raccordement électrique de l'élément piézo-électrique (1, 13, 33). Selon l'invention, le raccordement électrique de l'élément piézo-électrique (1, 13, 33) présente une grande sécurité de contact, car la languette de contact (5, 29, 31) est directement adjacente à la première électrode (3, 15, 17) et elle présente au moins un évidement (7, 25, 27, 39), dans lequel est placée de la colle (9) liant la languette de contact (5, 29, 31) à l'électrode (3, 15, 17).
