Abstract

Metal-sealing material-feedthrough, especially for devices which are subjected to high pressures, include at least one metal pin located in a sealing material in a feedthrough opening in a base body, whereby the at least one metal pin is enveloped at least partially by a conductive component element, so that a conductive connection may be created on the one hand between the component element and the metal pin and whereby on the other hand the component element is in contact with the base body, so that a conductive connection can be established between the component element and the base body, the component element possessing a design form to the extent that the component element with respect to its contour essentially follows the contour of the inside wall of the feedthrough opening along a section S.

Claims (25)

1. A metal-sealing material-feedthrough for a device which is subjected to high pressures, said metal-sealing material-feedthrough comprising:

a sealing material;

a base body including a feedthrough opening having an inside wall with a contour;

a component element which is conductive, said component element including an outer perimeter and a contour which essentially follows said contour of said inside wall of said feedthrough opening along a section of said feedthrough opening, said outer perimeter being noncircular; and

a first metal pin located in said sealing material in said feedthrough opening in said base body, said first metal pin being enveloped at least partially by said component element such that a first conductive connection can be established between said component element and said first metal pin, said component element being in contact with said base body such that a second conductive connection can be established between said component element and said base body, said component element not surrounding a second metal pin.

2. The metal-sealing material-feedthrough in accordance with claim 1 , further comprising a plurality of metal pins including at least said first metal pin and said second metal pin.

3. The metal-sealing material-feedthrough in accordance with claim 1 , wherein said component element includes an outside contour which is consistent, at least in a plurality of sections of said outside contour, essentially with said contour of said feedthrough opening, said contour of said feedthrough opening being an inside contour.

4. The metal-sealing material-feedthrough in accordance with claim 3 , wherein said inside wall has an inside surface with a first curvature, said component element having an outside surface with at least one second curvature, said first and second curvatures being essentially the same.

5. The metal-sealing material-feedthrough in accordance with claim 4 , wherein said feedthrough opening includes a hollow cylinder with a first radius, said outside surface of said component element having at least in a plurality of sections of said outside surface a second radius, said first radius largely corresponding with said second radius.

6. The metal-sealing material-feedthrough in accordance with claim 1 , further comprising a plurality of metal pins including only said first metal pin and said second metal pin, said first and second metal pins being located in said sealing material in said feedthrough opening, said component element enveloping said first metal pin.

7. The metal-sealing material-feedthrough in accordance with claim 1 , wherein said sealing material in said feedthrough opening has a first face and a second face, said first metal pin protruding on at least one of said first face and said second face from said sealing material, said component element being located at said second face on which said first metal pin protrudes beyond said sealing material.

8. The metal-sealing material-feedthrough in accordance with claim 7 , wherein said component element is flush with said second face.

9. The metal-sealing material-feedthrough in accordance with claim 1 , wherein said first metal pin is joined firmly with said sealing material, thereby resulting in a sealing material slug.

10. The metal-sealing material-feedthrough in accordance with claim 9 , wherein said first and second metal pins are fused with said sealing material.

11. The metal-sealing material-feedthrough in accordance with claim 1 , wherein said sealing material includes one of a glass slug formed by molten glass and a high efficiency polymer.

12. The metal-sealing material-feedthrough in accordance with claim 1 , wherein at least said feedthrough opening is stamped from said base body.

13. The metal-sealing material-feedthrough in accordance with claim 1 , wherein said base body is a punched component.

14. The metal-sealing material-feedthrough in accordance with claim 1 , wherein said component element is symmetrical.

15. The metal-sealing material-feedthrough in accordance with claim 14 , wherein said component element includes at least three outside surfaces, each of said at least three outside surfaces including a curve length and a radius of curvature, each said curve length being essentially the same, each said radius of curvature being essentially the same.

16. The metal-sealing material-feedthrough in accordance with claim 15 , wherein said at least three outside surfaces includes only three said outside surfaces.

17. The metal-sealing material-feedthrough in accordance with claim 1 , wherein said component element is a punched component.

18. A component element for a solder bridge of a metal-sealing material-feedthrough, said component element comprising:

an outer perimeter which is noncircular and includes at least three outside surfaces, each including a curve length and a radius of curvature, each said curve length being essentially the same, each said radius of curvature being essentially the same, the component element being symmetrical, said component element being configured for surrounding a first conductive pin but not a second conductive pin, each of said outside surfaces being configured for selectively following essentially a contour of an inside wall of a feedthrough opening of a base body of the metal-sealing material-feedthrough along a section of said feedthrough opening.

19. The component element in accordance with claim 18 , wherein said at least three outside surfaces includes only three said outside surfaces.

20. The component element in accordance with claim 18 , wherein the component element is a punched component.
