Abstract:
1. A method for securing a first sealing joint used on an electro-technical device, this electro-technical device comprising a functional unit and a container housing said functional unit, said container including at least one aperture provided with a cover which cover has at least one first face intended to abut an annular surface which borders on the aperture, and this through the agency of a first sealing joint accommodated in a first annular concave supporting area provided in at least one of the elements which are the container and the cover, is forcefully pushed in the direction of the annular surface, by means of restraining elements, this electro-technical device comprising a second sealing joint inserted between the annular surface which borders on the aperture and the first face of the cover: this method being characterised in that to insert the second sealing joint between the first annular surface which borders on the aperture and the first face of the cover: during a first operation, in at least one of the elements which are the container and the cover, a second annular concave supporting area is formed, which second annular concave supporting area surrounds the first annular concave supporting area by extending a first predetermined distance from said first annular concave supporting area, has a closed concavity not directly accessible from the exterior of the electro-technical device, during a second operation, after having applied the cover against the annular surface which borders on the aperture the second sealing joint is formed by moulding a sealing substance in the second annular concave supporting area in such a way that this sealing substance presses at one and the same time against the cover and against the container, characterised in that before forming the second sealing joint, the impermeability of the first sealing joint is checked through application of pressure of at least one second fluid of liquid type against a portion of the lateral face of said first sealing joint, this pressure being generated at least from the inside of the container.
