Abstract

An electrical connector arrangement for a turbomachine includes a support structure and a terminal with a terminal post projecting from the support structure along an axis. The electrical connector arrangement includes a connection stack that is supported by the terminal and arranged along the axis of the terminal post. The connection stack includes a bus bar that is electrically connected to the terminal post and that extends from the terminal post and the support structure. The connection stack includes a first deformable seal member and a second deformable seal member. The first deformable seal member is deformed against the terminal post to define an inner radial seal within the connection stack. The second deformable seal member is deformed against the support structure to define an outer radial seal within the connection stack.

First claim

What is claimed is:

1. An electrical connector arrangement for a turbomachine comprising:
a support structure;
a terminal with a terminal post projecting from the support structure along an axis;
a connection stack that is supported by the terminal and arranged along the axis of the terminal post, the connection stack including a compression member with a first step, the connection stack including a bus bar with a second step, the first step engaging the second step, the bus bar being electrically connected to the terminal post and extending from the terminal post and the support structure; and
the connection stack including a first deformable seal member and a second deformable seal member, the compression member deforming at least one of the first deformable seal member and the second deformable seal member, the first deformable seal member being deformed against the terminal post to define an inner radial seal within the connection stack, the second deformable seal member being deformed against the support structure to define an outer radial seal within the connection stack.

2. The electrical connector arrangement of claim 1 , wherein at least one of the first deformable seal member and the second deformable seal member is annular.

3. The electrical connector arrangement of claim 1 , further comprising a fastener that is threadably fastened to the terminal post to compress the connection stack.

4. The electrical connector arrangement of claim 1 , wherein the terminal further comprises a base member with an outer peripheral edge that is asymmetric with respect to the axis.

5. The electrical connector arrangement of claim 1 , further comprising a base member that connects the terminal post to the support structure; and
wherein the bus bar includes a retained bus end that is electrically connected to the terminal post and that is retained by the support structure, and wherein the bus bar includes an elongate end that extends from the retained bus end.

6. The electrical connector arrangement of claim 5 , wherein the support structure includes an opening, the terminal post projecting out from the opening, the opening including a lip that is spaced radially apart from the terminal post with respect to the axis, the retained bus end of the bus bar including an outer edge that is received within the opening underneath the lip to be retained by the support structure.

7. The electrical connector arrangement of claim 1 , wherein the first deformable seal member is received radially between the terminal post and an inner radial rim of the bus bar, and wherein the second deformable seal member is received radially between the bus bar and the support structure.

8. The electrical connector arrangement of claim 7 , wherein the first deformable seal member and the second deformable seal member are disposed generally at a common axial position with respect to the axis.

9. A method of manufacturing an electrical connector arrangement for a turbomachine comprising:
providing a support structure and a terminal with a terminal post projecting from the support structure along an axis;
supporting a connection stack on the terminal and along the axis of the terminal post, the connection stack including a compression member with a first step, the compression stack including a bus bar with a second step;
engaging the first step and the second step;
electrically connecting the bus bar to the terminal post with the bus bar extending from the terminal post and the support structure; and
deforming a first deformable seal member and a second deformable seal member of the connection stack, including compressing the compression member against at least one of the first deformable seal member and the second deformable seal member, deforming the first deformable seal member against the terminal post to define an inner radial seal within the connection stack, and deforming the second deformable seal member against the support structure to define an outer radial seal within the connection stack.

10. The method of claim 9 , further comprising advancing a fastener on the terminal post to deform the first deformable seal member and the second deformable seal member.

11. The method of claim 9 , wherein at least one of the first deformable seal member and the second deformable seal member is annular.

12. The method of claim 9 , further comprising connecting the terminal post to the support structure; and
further comprising retaining a retained bus end of the bus bar by the support structure and electrically connecting the retained bus end to the terminal post, and wherein the bus bar includes an elongate end that extends from the retained bus end.

13. The method of claim 12 , wherein the support structure includes an opening, the terminal post projecting out from the opening, the opening including a lip that is spaced radially apart from the terminal post with respect to the axis, and wherein retaining the retained bus end of the bus bar includes receiving an outer edge of the retained bus end within the opening underneath the lip to be retained by the support structure.

14. The method of claim 9 , wherein the first deformable seal member is received radially between the terminal post and an inner radial rim of the bus bar, and wherein the second deformable seal member is received radially between the bus bar and the support structure.

15. The method of claim 14 , wherein the first deformable seal member and the second deformable seal member are disposed generally at a common axial position with respect to the axis.

16. An electrical connector arrangement for a turbomachine comprising:
a support structure that includes an opening;
a terminal with a terminal post projecting out from the opening from the support structure along an axis, the opening including a lip that is spaced radially apart from the terminal post with respect to the axis;
a base member that connects the terminal post to the support structure;
a connection stack that is supported by the terminal and arranged along the axis of the terminal post, the connection stack including a bus bar that is electrically connected to the terminal post and that extends from the terminal post and the support structure, the bus bar including a retained bus end that is electrically connected to the terminal post and that is retained by the support structure, wherein the bus bar includes an elongate end that extends from the retained bus end, the retained bus end of the bus bar including an outer edge that is received within the opening underneath the lip to be retained by the support structure; and
the connection stack including a first deformable seal member and a second deformable seal member, the first deformable seal member being deformed against the terminal post to define an inner radial seal within the connection stack, the second deformable seal member being deformed against the support structure to define an outer radial seal within the connection stack.

17. The electrical connector arrangement of claim 16 , further comprising a fastener that is threadably fastened to the terminal post to compress the connection stack.

18. The electrical connector arrangement of claim 16 , wherein the terminal further comprises a base member with an outer peripheral edge that is asymmetric with respect to the axis.

19. The electrical connector arrangement of claim 16 , wherein the first deformable seal member is received radially between the terminal post and an inner radial rim of the bus bar, and wherein the second deformable se
