Abstract
Un dispositif pour transmettre des données entre les outils de fond de trou est décrit dans un mode de réalisation de la présente invention comme comprenant un noyau annulaire réalisé dans un matériau magnétiquement conducteur. Au moins un conducteur, isolé électriquement de la base annulaire, est enroulé autour du noyau annulaire. Un logement annulaire fabriqué d'un matériau électriquement conducteur est utilisé pour enfermer partiellement le noyau annulaire et la bobine conductrice. Le boîtier annulaire est formé pour résider dans un évidement annulaire formé dans la surface d'un outil de fond de trou et est isolé électriquement de la surface. Un élément de sollicitation est utilisé pour effectuer une sollicitation entre le boîtier annulaire et l'évidement annulaire, poussant le logement annulaire dans une direction sensiblement perpendiculaire à la surface.
