Box for electronic components, especially hybrid components, with high breakdown voltages

摘要

The present invention relates to a box for electronic components, especially hybrid components, with high breakdown voltage comprising a bottom (2), an enclosure (1) consisting of side walls (3, 4, 5, 6) and a cover (7) suitable for closing the said enclosure, at least one wall of the said enclosure including at least one orifice (8) for the passage of at least one electrical connector (9) suitable for linking the inside of the box with the outside, an insulation element (10) being threaded around each connector in the region of the orifice (8) of the side wall, characterised in that the said connector is, at least in a portion passing through the said wall, of cylindrical shape and coaxial with the said orifice, and in that the insulation element consisting of a glass or ceramic bead is produced in the form of a cylindrical sheath (10), threaded coaxially with the said electrical connector (9) in contact with the wall in the region of the orifice; the said sheath having a length which is greater than the thickness of the side wall in which it is engaged so as to exhibit, on either side of the said wall, protrusions (11, 12) with respect to the inside and the outside of the enclosure (1).
