Feedthrough connectors in glass

A feedthrough connector, comprising:

• an electrically insulating body formed out of glass, said electrically insulating body having a front side and a back side facing away from said front side, said electrically insulating body further having a circumferential lateral side extending from said front side to said back side of said electrically insulating body, and said electrically insulating body having a plurality of through-openings formed therein, each of said through-openings extending from said front side to said back side of said electrically insulating body, each of said through-openings defined by a respective first hole segment from front side into said body and a respective second hole segment from backside into said body axially, said respective first hole segment being offset from said respective second hole segment for defining a narrowing of said through-openings;
• first contact pads;
• second contact pads;
• a plurality of electrical conductors, each of said electrical conductors disposed in one of said through-openings such that each of said through-openings is hermetically sealed, wherein a respective conductor of said electrical conductors having a metallic material, said respective conductor having a first end disposed at said front side and connected to one of said first contact pads disposed on said front side, and an opposing second end disposed at said back side and connected to one of said second contact pads disposed on said back side;
• and
• a circumferential flange having a further metallic material, wherein said circumferential flange is connected to said circumferential lateral side of said electrically insulating body such that said circumferential flange surrounds said electrically insulating body and contacts said circumferential lateral side of said electrically insulating body.
