Abstract

A self-aligning grounding stud arrangement ( 100 ) for a housing ( 120 ) includes a grounding stud ( 210 ) that extends from a first end ( 212 ) outside the housing ( 120 ) to a second end ( 214 ) inside the housing ( 120 ). An anti-rotation flange ( 230 ) of the grounding stud ( 210 ) is received by an anti-rotation receiver ( 138 ) of the housing ( 120 ). The grounding stud ( 210 ) includes a first attachment feature ( 220 ) positioned between the first end ( 212 ) of the grounding stud ( 210 ) and the anti-rotation flange ( 230 ) and further includes a second attachment feature ( 260 ) positioned between the second end ( 214 ) of the grounding stud ( 210 ) and the anti-rotation flange ( 230 ). The housing ( 120 ) includes at least one guide ( 140 ) for rotationally orienting the anti-rotation flange ( 230 ) with the anti-rotation receiver ( 138 ).

First claim

What is claimed is:

1. A grounding stud arrangement comprising:
a grounding stud assembly including a grounding stud extending from a first end to a second end with an anti-rotation flange positioned between the first end and the second end of the grounding stud, the grounding stud including a first attachment feature positioned between the first end of the grounding stud and the anti-rotation flange and further including a second attachment feature positioned between the second end of the grounding stud and the anti-rotation flange; and
a housing including a wall with a hole and an anti-rotation receiver, a portion of the grounding stud positioned within the hole and at least a portion of the anti-rotation flange received by the anti-rotation receiver, the housing further including at least one guide for rotationally orienting the anti-rotation flange with the anti-rotation receiver.

2. The grounding stud arrangement of claim 1 , wherein the anti-rotation flange includes a faceted perimeter with at least one facet and wherein the anti-rotation receiver rotationally constrains the faceted perimeter of the anti-rotation flange.

3. The grounding stud arrangement of claim 2 , wherein the anti-rotation receiver is at least partially formed as a pocket including a bottom and a faceted perimeter with at least one facet, wherein the anti-rotation flange seats against the bottom of the anti-rotation receiver, and wherein the faceted perimeter of the anti-rotation receiver rotationally constrains the faceted perimeter of the anti-rotation flange.

4. The grounding stud arrangement of claim 3 , wherein the faceted perimeter of the anti-rotation receiver is a multi-faceted perimeter with a plurality of the facets and wherein the faceted perimeter of the anti-rotation flange is a multi-faceted perimeter with a plurality of the facets that engage the facets of the multi-faceted perimeter of the anti-rotation receiver, respectively.

5. The grounding stud arrangement of claim 4 , wherein the housing includes a plurality of the guides for rotationally orienting the anti-rotation flange with the anti-rotation receiver, wherein the guides are each an extension of one of the facets, respectively.

6. The grounding stud arrangement of claim 5 , wherein at least one of the facets does not include a corresponding one of the guides thereby providing a terminal exit.

7. The grounding stud arrangement of claim 5 , wherein the plurality of the guides together form a plurality of peaks and valleys.

8. The grounding stud arrangement of claim 7 , wherein the plurality of the guides includes contoured edges opposite the bottom of the anti-rotation receiver.

9. The grounding stud arrangement of claim 4 , wherein the multi-faceted perimeter of the anti-rotation receiver is a female hexagonal perimeter and wherein the multi-faceted perimeter of the anti-rotation flange is a male hexagonal perimeter that engages the female hexagonal perimeter.

10. The grounding stud arrangement of claim 1 , further comprising a sealing member positioned between the grounding stud and the housing.

11. The grounding stud arrangement of claim 10 , wherein the grounding stud includes an O-ring groove and wherein the sealing member is an O-ring positioned at least partially within the O-ring groove.

12. The grounding stud arrangement of claim 3 , further comprising a sealing member positioned between the anti-rotation flange and the bottom of the anti-rotation receiver.

13. The grounding stud arrangement of claim 12 , wherein the anti-rotation flange includes an O-ring groove and wherein the sealing member is an O-ring positioned at least partially within the O-ring groove.

14. A method of assembling the grounding stud arrangement of claim 1 , the method comprising:
providing the housing;
inserting the second end of the grounding stud through the hole of the housing; and
rotationally orienting the anti-rotation flange of the grounding stud with the anti-rotation receiver of the housing by engaging the anti-rotation flange with the at least one guide of the housing and further inserting the grounding stud through the hole.

15. The method of claim 14 , further comprising seating the anti-rotation flange of the grounding stud against a bottom of the anti-rotation receiver.

16. The method of claim 15 , further comprising installing a sealing member over the second end of the grounding stud before inserting the second end of the grounding stud through the hole of the housing and compressing the sealing member between the anti-rotation flange of the grounding stud and the bottom of the anti-rotation receiver.

17. The method of claim 15 , further comprising attaching the grounding stud to the housing by threading threads of a first nut onto threads of the second attachment feature.

18. The method of claim 17 , further comprising attaching a first terminal to the grounding stud by positioning the first terminal on the grounding stud and threading threads of a second nut onto the threads of the second attachment feature and thereby clamping the first terminal between the first nut and the second nut.

19. The method of claim 18 , further comprising attaching a second terminal to the grounding stud by positioning the second terminal on the grounding stud and threading threads of a third nut onto threads of the first attachment feature and thereby clamping the second terminal between the third nut and the anti-rotation flange.
