Electrical feedthrough glass-metal electrodes

An electrical device, comprising:

• a housing part, the housing part being a monolithic structure;
• a feedthrough extending through the housing part, the housing part having a material thickness T and is made of metal, the metal being iron, iron alloys, iron-nickel alloys, iron-nickel-cobalt alloys, KOVAR, steel, stainless steel, high-grade steel, aluminum, aluminum alloys, AlSiC, magnesium, magnesium alloys, titanium or titanium alloys, wherein the housing part has at least one opening, wherein the opening receives a contact element consisting of a conductive material in a glass or glass ceramic material, the housing part having a collar in the region of the opening, the collar forms an inner wall of the feedthrough at the opening, the inner wall having a height H which is greater than the material thickness T, wherein a glazing length EL of the glass or the glass ceramic material corresponds to the height H, wherein the housing part includes a flange for connection with a housing, the flange including a connecting region, the flange has a free space F between a raised or a lowered region providing the glazing length and the connecting region, wherein the flange is a flexible flange, the glass or the glass ceramic material being at least partly in contact with the opening of the housing part, the flange being nonparallel relative to the collar.
