Abstract
An insulating electrical feed-through connector extending through a wall of aluminium is obtained by using a sintered sleeve comprising phosphate glass in which a conductive pin is inserted. The sleeve is raised to a firing temperature in excess of the dilatometric softening temperature of the vitreous material in the presence of a first effective quantity of alumina between the sleeve and the wall and of a second effective quantity of nickel oxide between the sleeve and the pin, which makes it possible to achieve a simultaneous and direct hermetic sealing of the sleeve to the wall and of the pin to the sleeve.
