Abstract

A feed-through is provided that includes a flange and a first functional component. The flange has a through-opening in which the first functional component is arranged and is connected to the flange such that the through-opening is sealed. The first functional component has at least one deformation region, in which a recess is provided such that the mechanical stability of the first functional component is reduced in the deformation region. In this manner, the first functional element can be deformed in the deformation area when mechanical load is applied.

First claim

What is claimed is:

1. A feed-through comprising:
a flange having a through-opening with an inner wall;
a first functional component arranged within the through-opening and connected to the flange such that the through-opening is sealed; and
a second functional component connected with the first functional component in a gap-free manner at least at opposite ends by connection material,
the first functional component being formed substantially from at least one metal and having at least one deformation region that is deformable when mechanical load is applied, and
the at least one deformation region being formed by at least one recess that locally penetrates through the first functional component or reduces a material thickness thereof such that a mechanical stability of the first functional component is reduced in the at least one deformation region, wherein the first functional component is arranged in the through-opening so as to form a hollow space between the inner wall and the at least one deformation region and so that the at least one deformation region is between the connection material at the opposite ends.

2. The feed-through according to claim 1 , wherein the first functional component is formed substantially from at least one metal and having at least two separate tube portions that are connected to the second functional component.

3. The feed-through according to claim 2 , wherein the deformation region is formed by spacing between the at least two separate tube portions of the first functional component so that the at least two separate tube portions of the first functional component can move relative to each other when the mechanical load is applied.

4. The feed-through according to claim 2 , wherein the first functional component is formed in a tubular manner at least in portions, the second functional component is arranged in the tubular portions.

5. The feed-through according to claim 4 , wherein the second functional component comprises at least two portions, which, with extension and/or compression of the deformation region along a longitudinal axis thereof, can be moved in a directed selected from the group consisting of distended and/or compressed with respect to one another, tilted with respect to one another, twisted with respect to one another, subjected to a shear stress relative to one another, and combinations thereof.

6. The feed-through according to claim 5 , wherein the two portions of the second functional component are connected by a flexible structure.

7. The feed-through according to claim 5 , wherein the two portions of the second functional component are connected by structures that engage with one another and are interconnected in an extendable and/or retractable manner.

8. The feed-through according to claim 1 , wherein the first functional component is connected to the flange.

9. The feed-through according to claim 8 , wherein the first functional component is connected to the flange by at least two separate insulation components in a manner electrically insulated by the flange and is held in the through-opening, wherein the insulation components form the hollow space therebetween and between the inner wall of the through-opening and the first functional component.

10. The feed-through according to claim 9 , further comprising at least one monitoring opening running through the flange and/or at least one of the two separate insulation components.

11. The feed-through according to claim 10 , wherein the hollow space is connectable by the at least one monitoring opening to a measuring instrument.

12. The feed-through according to claim 10 , wherein fluid can be introduced into and/or discharged from the hollow space through the at least one monitoring opening.

13. The feed-through according to claim 1 , wherein the first functional component is tubular and wherein the deformation region is at least one recess in the first functional component, the at least one recess connecting the interior of the first functional component and the hollow space.

14. The feed-through according to claim 1 , wherein the first functional component is selected from the group consisting of electrical conductors made of solid material, tube components made of at least one metal, and combinations thereof.

15. The feed-through according to claim 14 , wherein the second functional component is selected from the group consisting of electrical conductors, thermocouple wires, optical waveguides, waveguides, and combinations thereof.

16. Use of the feed-through according to claim 1 in a containment structure selected from the group consisting of a pressure vessel, a reactor chamber, a pump housing, a generator housing, and combinations thereof.

17. The feed-through according to claim 1 , wherein the connection material is a material selected from the group consisting of glass, glass-ceramic, ceramic, metal, metal solder, welded connection, and plastics.

18. A feed-through comprising:
a flange having a through-opening with an inner wall;
a first functional component arranged within the through-opening;
material connecting the first functional component to the inner wall of the through-opening at least at opposite ends of the flange,
the first functional component being formed substantially from at least one metal and having at least one deformation region that is deformable when mechanical load is applied, and
the at least one deformation region being formed by at least one recess that locally penetrates through the first functional component or reduces a material thickness thereof such that a mechanical stability of the functional component is reduced in the at least one deformation region, wherein the first functional component is arranged in the through-opening so as to form a hollow space between the inner wall and the at least one deformation region and so that the at least one deformation region is between the material at the opposite ends.

19. The feed-through according to claim 18 , wherein the material is selected from the group consisting of glass, glass-ceramic, ceramic, metal, metal solder, welded connection, and plastics.

20. The feed-through according to claim 18 , wherein the first functional component comprises two separate portions, one of the two separate portions being connected to the flange by the material at one of the opposite ends and another of the two separate portions being connected to the flange by the material at another of the opposite ends.

21. The feed-through according to claim 20 , wherein the deformation region is formed by spacing between the two separate portions of the first functional component so that the two separate portions of the first functional component can move relative to each other when the mechanical load is applied.

22. The feed-through according to claim 18 , wherein the second functional component is in the first functional component.

23. The feed-through according to claim 22 , wherein the second functional component is connected to the first functional component in a gap-free manner at least at opposite ends of the first functional component by additional material.

24. The feed-through according to claim 18 , further comprising a step on at least one of the inner wall and an outer portion of the first functional component, the step being arranged where the material connects the first functional component to the flange.
