Abstract

An electrical feed through assembly includes a mechanical connector extending between a first end and a second end. The mechanical connector defines at least one opening through the mechanical connector between the first end and the second end. The electrical feed through assembly includes a first electrical connector attached to the first end of the mechanical connector. The first electrical connector includes a conductor portion that extends through the at least one opening in the mechanical connector. The first electrical connector includes a grounded portion within which the conductor portion is received. An inner radial surface of the grounded portion is sealed with the conductor portion. An outer radial surface of the grounded portion is attached to the mechanical connector.

First claim

What is claimed is:

1. An electrical feed through assembly comprising:
a mechanical connector including a first end and a second end, the mechanical connector defining at least one opening through the mechanical connector between the first end and the second end;
a first electrical connector configured to be attached to the first end of the mechanical connector, the first electrical connector including:

a conductor portion configured to extend through the at least one opening in the mechanical connector; and
a hollow grounded portion defining a channel within which the conductor portion is received and spaced radially inward away from the grounded portion, an inner radial surface of the grounded portion configured to be sealed with the conductor portion, an outer radial surface of the grounded portion configured to be attached to the mechanical connector, and the grounded portion extending continuously through the at least one opening between the first end and the second end.

2. The electrical feed through assembly of claim 1 , wherein the attachment between the outer radial surface of the grounded portion and the mechanical connector includes a seal.

3. The electrical feed through assembly of claim 2 , wherein the seal between the outer radial surface of the grounded portion and the mechanical connector includes a hermetic seal.

4. The electrical feed through assembly of claim 1 , wherein a hermetic seal is provided to seal between the inner radial surface of the grounded portion and the conductor portion.

5. The electrical feed through assembly of claim 1 , wherein a second electrical connector is configured to be attached to the second end of the mechanical connector.

6. The electrical feed through assembly of claim 5 , wherein the second electrical connector includes:
a second conductor portion that is configured to extend through the at least one opening in the mechanical connector; and
a second grounded portion within which the second conductor portion is received, an inner radial surface of the second grounded portion configured to be sealed with the second conductor portion, an outer radial surface of the second grounded portion configured to be attached to the mechanical connector.

7. The electrical feed through assembly of claim 6 , wherein the attachment between the outer radial surface of the second grounded portion and the mechanical connector includes a seal.

8. The electrical feed through assembly of claim 7 , wherein the seal between the outer radial surface of the second grounded portion and the mechanical connector includes a hermetic seal.

9. The electrical feed through assembly of claim 6 , wherein the conductor portion of the first electrical connector and the second conductor portion of the second electrical connector are electrically connected.

10. The electrical feed through assembly of claim 1 , wherein the conductor portion extends substantially continuously through the opening in the mechanical connector between the first end and the second end.

11. The electrical feed through assembly of claim 10 , wherein the grounded portion extends substantially continuously through the opening in the mechanical connector between the first end and the second end.

12. The electrical feed through assembly of claim 11 , wherein a first location of the grounded portion at the outer radial surface is configured to be attached to the mechanical connector adjacent the first end of the mechanical connector.

13. The electrical feed through assembly of claim 1 , wherein a hermetic seal between the outer radial surface of the grounded portion and the mechanical connector is resistant to a leakage pressure of up to about 7 megapascal (MPa).

14. An electrical feed through assembly comprising:
a mechanical connector extending between a first end and a second end, the mechanical connector defining at least one opening through the mechanical connector between the first end and the second end;
a first electrical connector configured to be attached to the first end of the mechanical connector, the first electrical connector including:

a conductor portion that is configured to extend through the at least one opening in the mechanical connector; and
a hollow grounded portion defining a channel within which the conductor portion is received and spaced radially inward away from the grounded portion, an outer radial surface of the grounded portion configured to be hermetically sealed to the mechanical connector, and the grounded portion extending continuously through the at least one opening between the first end and the second end.

15. The electrical feed through assembly of claim 14 , wherein the hermetic seal between the outer radial surface of the grounded portion and the mechanical connector includes a glass to metal seal.

16. The electrical feed through assembly of claim 14 , wherein the hermetic seal between the outer radial surface of the grounded portion and the mechanical connector is resistant to a leakage pressure of up to about 7 megapascal (MPa).

17. The electrical feed through assembly of claim 16 , wherein the hermetic seal between the outer radial surface of the grounded portion and the mechanical connector is resistant to a leakage pressure of up to about 10 megapascals (MPa).

18. The electrical feed through assembly of claim 14 , wherein the grounded portion is configured to be sealed with the conductor portion.

19. The electrical feed through assembly of claim 18 , wherein the seal between the grounded portion and the conductor portion is resistant to a leakage pressure of up to about 10 megapascal (MPa).

20. An electrical feed through assembly comprising:
a mechanical connector extending between a first end and a second end, the mechanical connector defining at least one opening through the mechanical connector between the first end and the second end;
a first electrical connector configured to be attached to the first end of the mechanical connector, the first electrical connector including:

a conductor portion that is configured to extend through the at least one opening in the mechanical connector; and
a hollow grounded portion defining a channel within which the conductor portion is received and spaced radially inward away from the grounded portion, an inner radial surface of the grounded portion configured to be sealed with the conductor portion, an outer radial surface of the grounded portion configured to be attached to the mechanical connector, and the grounded portion extending continuously through the at least one opening between the first end and the second end;

a second electrical connector configured to be attached to the second end of the mechanical connector, the second electrical connector including:
a second conductor portion that is configured to extend through the at least one opening in the mechanical connector, the second conductor portion electrically connected to the conductor portion of the first electrical connector; and
a second hollow grounded portion defining a second channel within which the second conductor portion is received and spaced radially inward away from the second grounded portion, an inner radial surface of the second grounded portion configured to be sealed with the second conductor portion, an outer radial surface of the second grounded portion configured to be attached to the mechanical connector, and the second grounded portion extending continuously through the at least one opening between the first end and the second
