Compressor hermetic terminal

1. A compressor comprising:

a shell having an inner surface and an outer surface;

an aperture in said shell;

a drive mechanism disposed within said shell;

a compression mechanism driven by said drive mechanism;

a hermetic terminal assembly including a housing extending through said aperture and surrounded by an annular flange including a leg portion;

a projection on said leg portion having a thickness greater than said leg portion and secured to said inner surface of said shell.

2. The compressor of claim 1 , wherein a thickness of said projection is approximately equal to a thickness of said housing.

3. The compressor of claim 1 , wherein a ratio of a thickness of said projection compared to a thickness of said housing is between 0.5-0.75.

4. The compressor of claim 1 , wherein said housing includes a wall, said wall and said leg portion having a thickness that is less than a thickness of said projection.

5. The compressor of claim 4 , wherein a ratio of a thickness of said projection compared to a thickness of said wall and said leg portion is between 1.5-2.0.

6. The compressor of claim 4 , wherein a ratio of a thickness of said projection compared to a thickness of said wall and said leg portion is between 2.0-3.0.

7. The compressor of claim 1 , wherein said projection is secured to said inner surface approximately a shell thickness away from said aperture.

8. The compressor of claim 1 , wherein said projection is secured to said inner surface at least a shell thickness away from said aperture.

9. A compressor comprising:

a shell having an inner surface and an outer surface;

an aperture formed in said shell;

a drive mechanism disposed within said shell;

a compression mechanism driven by said drive mechanism; and

a hermetic terminal assembly including a housing extending through said aperture and an annular flange surrounding said housing,

said annular flange including a projection secured to said inner surface of said shell a distance away from said aperture and a leg portion connecting said projection to said housing.

10. The compressor of claim 9 , wherein a thickness of said projection is approximately equal to a thickness of said housing.

11. The compressor of claim 9 , wherein a ratio of a thickness of said projection compared to a thickness of said housing is between 0.5-0.75.

12. The compressor of claim 9 , wherein said leg portion includes a thickness that is less than a thickness of said housing.

13. The compressor of claim 12 , wherein a ratio of a thickness of said projection compared to a thickness of said leg portion is between 1.5-2.0.

14. The compressor of claim 12 , wherein a ratio of a thickness of said projection compared to a thickness of said leg portion is between 2.0-3.0.

15. The compressor of claim 9 , wherein said distance is approximately a shell thickness away from said aperture.

16. The compressor of claim 9 , wherein said projection is secured to said inner surface at least a shell thickness away from said aperture.

17. The compressor of claim 9 , further comprising a lip portion provided radially outward said projection.

18. A compressor comprising:

a shell having an inner surface and an outer surface;

an aperture formed in said shell;

a drive mechanism disposed within said shell;

a compression mechanism driven by said drive mechanism;

a hermetic terminal assembly provided in said aperture and including a housing; and

an annular flange attached to and surrounding said housing, said annular flange including a leg portion having an area of increased thickness.

19. The compressor of claim 18 , wherein a thickness of said leg portion at said area of increased thickness is approximately equal to a thickness of said housing.

20. The compressor of claim 18 , wherein a ratio of a thickness of said area of increased thickness compared to a thickness of said housing is between 0.5-0.75.

21. The compressor of claim 18 , wherein said leg portion includes a thickness that is less than a thickness of said housing at a location extending between said housing and said area of increased thickness.

22. The compressor of claim 18 , wherein a ratio of a thickness of said area of increased thickness compared to a thickness of said leg portion is between 1.5-2.0.

23. The compressor of claim 18 , wherein a ratio of a thickness of said area of increased thickness compared to a thickness of said leg portion is between 2.0-3.0.

24. The compressor of claim 18 , wherein said area of increased thickness is welded to said inner surface approximately a shell thickness away from said aperture.

25. The compressor of claim 18 , wherein said area of increased thickness is secured to said inner surface at least a shell thickness away from said aperture.

26. The compressor of claim 18 , further comprising a lip portion provided radially outward said area of increased thickness.
