Abstract

L'invention a pour objet des dispositifs isolants et étanches pour faire passer un conducteur électrique à travers une cloison. Un dispositif selon l'invention pour faire passer un conducteur 6a, 6b à travers une cloison 4, comporte deux alésages coaxiaux 20 et 21 reliés entre eux par un épaulement 22. A l'intérieur de ceux-ci, on engage une perle de verre 11 comportant une collerette 12 qui s'appuie sur l'épaulement 22. On remplit le vide d'un bouclier thermique 24 constitué par une résine époxyde, son durcisseur et une charge de gel de silice pulvérulent. Une application est sur un engin autopropulsé par un propulseur à poudre, les traversées de la cloison qui séparent le propulseur du compartiment contenant les circuits électroniques.
