Abstract
An electrical passage for an hermetic enclosure including electronic elements comprises a conducting piece (2) traversing an insulating sleeve (3) bearing on the inner surface (1) of the enclosure. A ring (7) surrounds the conducting piece (2) and a portion of the insulating sleeve (3) projecting outside of the enclosure, and a nut (13) inserted onto the conducting piece (2) ensures fastening of the assembly. A full ring seal (10) disposed between the inner surface (11) of the ring (7) and the outer surface (12) of the insulating sleeve (3) is compressed longitudinally by the outer wall (8) of the enclosure and by a shoulder (6) of the conducting piece, thus ensuring the hermeticity of the assembly. The tightening of the nut (13) acts on the insulating sleeve (3) within the enclosure. The invention has application to the electrical connection of power semiconductors utilized within the domain of railway traction.
