Abstract

A terminal assembly includes a terminal board with an interrupted aperture to receive a passthrough.

Claims

1. A terminal assembly comprising:

a terminal board with an interrupted aperture and an interface defined at least partially around said interrupted aperture;

a passthrough with a first radially extending flange and a second radially extending flange, said passthrough extends through said interrupted aperture and said first radially extending flange engaged with said interface; and

a terminal post mounted to said terminal board along a first axis, said passthrough being defined along a second axis offset from said first axis.

2. The terminal assembly as recited in claim 1, wherein said interface is semi-circular.

3. The terminal assembly as recited in claim 1, wherein said first radially extending flange includes a stepped surface between a first radially extending flange section of a diameter greater than said second radially extending flange and a second radially extending flange section of a diameter generally equivalent to said second radially extending flange.

4. The terminal assembly as recited in claim 3, wherein said first radially extending flange section is engaged with said interface.

5. The terminal assembly as recited in claim 4, wherein said interface is semi-circular.

6. The terminal assembly as recited in claim 1, further comprising a terminal connection that extends through said passthrough and is in electrical contact with said terminal post.

7. The terminal assembly as recited in claim 1, wherein said interrupted aperture has an open lateral side and opposed open ends at respective opposed sides of the terminal board.

8. A terminal assembly comprising:

a terminal board with an interrupted aperture, said terminal board including an interface defined at least partially around said interrupted aperture, said interface being semi-circular; and

a passthrough with a first radially extending flange and a second radially extending flange, said first radially extending flange of a diameter greater than said second radially extending flange, said passthrough extends through said interrupted aperture.

9. The terminal assembly as recited in claim 8, wherein said first radially extending flange is engaged with said interface.

10. The terminal assembly as recited in claim 8, further comprising a terminal post mounted to said terminal board along a first axis and said passthrough is defined along a second axis offset from said first axis.

11. The terminal assembly as recited in claim 10, further comprising a terminal connection that extends through said passthrough and is in electrical contact with said terminal post.

12. The terminal assembly as recited in claim 8, wherein said interrupted aperture has an open lateral side and opposed open ends at respective opposed sides of the terminal board.

13. A starter-generator for a gas turbine engine comprising:

a housing having a bore;

a terminal board mounted to said housing with an interrupted aperture aligned with said bore and an interface defined at least partially around said interrupted aperture, said terminal board including an interface defined at least partially around said interrupted aperture, said interface being semi-circular; and

a passthrough with a first radially extending flange and a second radially extending flange, said passthrough extends through said interrupted aperture, said first radially extending flange engaged with said interface, and said a second radially extending flange located within said bore.

14. The starter-generator for a gas turbine engine as recited in claim 13, wherein said first radially extending flange includes a stepped surface between a first radially extending flange section of a diameter greater than said second radially extending flange and a second radially extending flange section of a diameter generally equivalent to said second radially extending flange.

15. The starter-generator as recited in claim 13, further comprising a terminal post mounted to said terminal board along a first axis, and said passthrough being defined along a second axis offset from said first axis.

16. The starter-generator as recited in claim 13, wherein said interrupted aperture has an open lateral side and opposed open ends at respective opposed sides of the terminal board.

17. A method of installing a terminal assembly in a starter-generator comprising:

installing a passthrough with a first radially extending flange and a second radially extending flange at least partially through an interrupted aperture of a terminal board with a semi-circular interface defined around the interrupted aperture, the first radially extending flange engaged with the interface.

18. The method as recited in claim 17, wherein the first radially extending flange includes a stepped surface between a first radially extending flange section of a diameter greater than the second radially extending flange and a second radially extending flange section of a diameter generally equivalent to the second radially extending flange.

19. The method as recited in claim 17, further comprising mounting a terminal post to the terminal board along a first axis.

20. The method as recited in claim 19, further comprising mounting the passthrough along a second axis offset and parallel to the first axis.

21. The method as recited in claim 17, wherein said interrupted aperture has an open lateral side and opposed open ends at respective opposed sides of the terminal board.
