Abstract

The subject disclosure relates to a water-tight sealed stud assembly for high current applications. The water-tight sealed stud assembly can include a stud, a sealing ring, a sleeve, and a body. The stud may have a stud base and a thickened portion having an annular groove. The sealing ring may be disposed in the annular groove. The sleeve may be disposed circumferentially around the stud and made of a conductive material. The body may be disposed circumferentially around the sleeve and made of a non-conductive material. Systems and methods are also provided.

First claim

What is claimed:

1. A water-tight sealed stud assembly for high current applications comprising:
a stud comprising a stud base and a thickened portion, the thickened portion having an annular groove;
a sealing ring disposed in the annular groove;
a sleeve disposed circumferentially around the stud, wherein the sleeve is comprised of a conductive material;
a body disposed circumferentially around the sleeve, wherein the body is comprised of a non-conductive material; and
an outer sealing ring is overmolded circumferentially around the body.

2. The water-tight sealed stud assembly of claim 1 , wherein mechanical interference between the thickened portion of the stud, the sealing ring disposed in the annular groove, and the sleeve form a water-tight seal.

3. The water-tight sealed stud assembly of claim 1 , wherein the sleeve is configured to receive a harness adjacent to an upper end of the stud.

4. The water-tight sealed stud assembly of claim 1 , wherein the conductive material is copper.

5. The water-tight sealed stud assembly of claim 1 , wherein a distance between the sleeve and the stud base is configured to receive a board, wherein the board receives a current through the sleeve.

6. The water-tight sealed stud assembly of claim 1 , wherein a distance between the sleeve and the stud base is configured to receive a board, wherein the stud is configured to threadedly receive a sealing nut, and wherein, when the sealing nut is threaded onto the stud, the distance between the sleeve and the stud is reduced to secure the board.

7. The water-tight sealed stud assembly of claim 1 , further comprising:
a cover plate attached to the outer sealing ring disposed circumferentially around the body.

8. An automated driving system computer comprising:
one or more processors attached to a board disposed in a housing;
a stud comprising a stud base and a thickened portion, the thickened portion having an annular groove, the stud disposed in the housing;
a sealing ring disposed in the annular groove;
a sleeve disposed circumferentially around the stud and in the housing, wherein the sleeve is comprised of a conductive material;
a body disposed circumferentially around the sleeve and in the housing, wherein the body is comprised of a non-conductive material;
an outer sealing ring disposed circumferentially around the body, and
a cover plate attached to the outer sealing ring disposed circumferentially around the body
wherein the stud base attaches to the board.

9. The automated driving system computer of claim 8 , wherein mechanical interference between the thickened portion of the stud, the sealing ring disposed in the annular groove, and the sleeve form a water-tight seal.

10. The automated driving system computer of claim 8 , wherein the sleeve is configured to receive a harness adjacent to an upper end of the stud.

11. The automated driving system computer of claim 8 , wherein the conductive material is copper.

12. The automated driving system computer of claim 8 , wherein a distance between the sleeve and the stud base is configured to receive a board, wherein the board receives a current through the sleeve.

13. The automated driving system computer of claim 8 , wherein a distance between the sleeve and the stud base is configured to receive a board, wherein the stud is configured to threadedly receive a sealing nut, and wherein, when the sealing nut is threaded onto the stud, the distance between the sleeve and the stud is reduced to secure the board.

14. The automated driving system computer of claim 8 , wherein the outer sealing ring is overmolded circumferentially around the body.

15. A method comprising:
disposing a sealing ring in an annular groove in a thickened portion of a stud;
disposing a sleeve circumferentially around the stud, wherein the sleeve is comprised of a conductive material;
disposing a body circumferentially around the sleeve, wherein the body is comprised of a non-conductive material; and
disposing an outer sealing ring overmolded circumferentially around the body.

16. The method of claim 15 , further comprising:
forming a water-tight seal via a mechanical interference between the thickened portion of the stud, the sealing ring disposed in the annular groove, and the sleeve.

17. The method of claim 15 , further comprising:
configuring the sleeve to receive a harness adjacent to an upper end of the stud.

18. The method of claim 15 , wherein the conductive material is copper.
