Abstract

A feed-through, in particular a feed-through which passes through part of a housing, in particular a battery housing, for example made of metal, in particular light metal, for example aluminum, an aluminum alloy, AlSiC, magnesium, an magnesium alloy, titanium, a titanium alloy, steel, stainless steel or high-grade steel. The housing part has at least one opening through which at least one conductor, in particular an essentially pin-shaped conductor, embedded in a glass or glass ceramic material, is guided. The base body is, for example, an essentially annular-shaped base body.

10. The housing part according to claim 7 , wherein an additional material which is one of a glass and a glass ceramic material is introduced between said base body and said at least one conductor.

11. The housing part according to claim 10 , wherein said additional material which is one of a glass and a glass ceramic material has a sealing temperature which is lower than a melting temperature of at least one of said base body and said conductor.

12. The housing part according to claim 7 , wherein said essentially pin-shaped conductor includes a head part having a head surface which is larger than a surface of said pin-shaped conductor.

13. The housing part according to claim 12 , wherein at least one of said head part and said pin-shaped conductor has a round or an oval external form and said one of a glass material and a glass ceramic material is positioned between said pin-shaped conductor and said base body or between said head part and said base body.

14. The housing part according to claim 1 , wherein said base body is in a region of said at least one opening and is hermetically sealed with the housing part by one of welding, soldering, pressing, crimping and shrinking.

15. The housing part according to claim 1 , wherein said relief device includes at least one of a groove and a protrusion.
