ABSTRACT:
A sealing device for an enclosure containing an expandable fluid, particularly for high-voltage connectors, ensures fluid-tightness over a broad temperature range and provides a safety function by accommodating variations in volume of the fluid by the use of an O-ring seal displaceably clamped within an annular recess. A sectional length L1 of the recess in which the seal can take up n positions is constituted by an initial-clamping space and by a clearance space into which the seal can penetrate under the pressure of fluid.
