Abstract

Dispositif de retenue dans lequel est logé un corps conducteur de type aiguille excité de l'extérieur par une bobine, de manière à permettre un mouvement dans le sens longitudinal. Ledit dispositif de retenue comporte un isolant inorganique faisant face à un objet inspecté et un isolant intermédiaire formé d'une résine isolante. L'isolant inorganique, qui empêche la sortie du corps conducteur de type aiguille, est formé d'une première plaque de matière inorganique faisant face à l'objet inspecté et d'une seconde plaque constituée de la résine isolante, qui sont collées l'une à l'autre.
