Abstract
Un dispositif est décrit pour isoler des chocs et des vibrations les outils de fond de trou logés dans un train de forage, tout en maintenant lalignement rotationnel et offrant un branchement électrique continue entre les extrémités de loutil le long dune pluralité de lignes dinterconnexion. Le dispositif accroît la durée de vie utile des outils tout en réduisant les dommages lors du fonctionnement dans des environnements exigeants.
