Abstract

Parafoudre pentapolaire à gaz. Il se distingue en ce que le boîtier 2 constituant par lui-même l'électrode de masse incorpore un fond supérieur 22 dont la face interne, plane, est disposée à distance calibrée d'un plan commun aux faces frontales des quatre électrodes actives 11 -14 en forme de cylindres métalliques pleins, emmanchés sur des broches 111 -114 , en ce que ladite face interne du fond supérieur du boîtier est au préalable revêtue ou garnie, dans au moins une gorge 24 de forme géométrique régulière et coaxiale, d'au moins un matériau 23 en lui-même connu à faible travail de sortie des électrons, et en ce que le pied 3 du boîtier est une pièce distincte en un matériau tel qu'alliage fer-nickel-cobalt dit KOVAR, permettant les traversées étanches à l'air de perles de verre ou céramique 41 -44 par lesdites broches, ainsi que la fermeteure étanche du boîtier. Utilisable notamment sur équipements téléphoniques.
