Abstract

L'invention a pour objet un détecteur de fuites comprenant deux électrodes pouvant être pontées par un liquide issu d'une fuite. Ce détecteur est caractérisé en ce que l'une des électrodes est constituée par une pièce concave en forme de coupe 20, tandis que l'autre est constituée par le prolongement 28 d'une électrode axiale 27 d'une douille de connexion coaxiale 24, ledit prolongement se terminant peu avant le plan qui passe par le bord de la pièce concave 20.The subject of the invention is a leak detector comprising two electrodes which can be bridged by a liquid resulting from a leak. This detector is characterized in that one of the electrodes is formed by a concave cup-shaped part 20, while the other is formed by the extension 28 of an axial electrode 27 of a coaxial connection socket 24, said extension ending shortly before the plane which passes through the edge of the concave part 20.
