Abstract

A terminal board includes a base portion with a length; a plurality of terminals extending from the base portion; and a plurality of barriers extending from the base portion between terminals and having a barrier spacing distance between each barrier. The ratio of length to barrier spacing distance is at least 5.124:1. The terminal board can be connected to a starter-generator housing for outputting power from the starter-generator.

Claims

1. A terminal board comprising:

a base portion with a length;

a plurality of terminals extending from the base portion; and

a plurality of barriers extending from the base portion between terminals and having a barrier spacing distance between each barrier;

wherein the ratio of length to barrier spacing distance is at least 5.124;

1.

2. The terminal board of claim 1, wherein the at least one barrier extends from base portion at least 1.334 cm (0.525 inches).

3. The terminal board of claim 1, wherein the at least one barrier has a thickness of at least 0.399 cm (0.157 inches).

4. The terminal board of claim 1, wherein the terminal board base has four terminals and three barriers.

5. The terminal board of claim 1, wherein the terminal board length is at least 15.250 cm (6.004 inches).

6. A terminal assembly comprising:

a terminal board with a plurality of terminals and at least one terminal board barrier separating each of the plurality of terminals, the terminal board having a length of at least 15.250 cm (6.004 inches); and

a terminal cover to cover the terminal board and having at least one cover barrier extending from an inside of the terminal cover.

7. The terminal assembly of claim 6, wherein the at least one terminal board barrier extends from the terminal board at least 1.334 cm (0.525 inches).

8. The terminal assembly of claim 6, wherein the at least one terminal board barrier has a thickness of at least 0.399 cm (0.157 inches).

9. The terminal assembly of claim 6, wherein the terminal board has four terminals and three terminal board barriers.

10. The terminal assembly of claim 9, wherein the terminal cover has three cover barriers that align with the three terminal board barriers.

11. The terminal assembly of claim 6, wherein the terminal cover connects to the terminal board with fasteners.

12. The terminal assembly of claim 6, wherein the terminal board has a plurality of barriers and the ratio of length to barrier spacing is at least 5.124:

1.

13. A starter-generator comprising:

a housing;

a terminal board with an overall length mounted to the housing with a plurality of terminals and a plurality of terminal board barriers separated by barrier spacing lengths; and

a terminal cover to mount over the terminal board, the terminal cover with a plurality of cover barriers aligned with and extending toward the plurality of terminal board barriers, wherein the ratio of overall terminal board length to barrier spacing lengths is at least 5.124;

1.

14. The starter-generator of claim 13, wherein each of the plurality of terminal board barriers extends from the terminal board at least 1.334 cm (0.525 inches).

15. The starter-generator of claim 13, wherein each of the plurality of terminal board barriers has a thickness of at least 0.399 cm (0.157 inches).

16. The starter-generator of claim 13, wherein the terminal board has four terminals and three terminal board barriers.

17. The starter-generator of claim 16, wherein the terminal cover has three cover barriers that align with the three terminal board barriers.

18. The starter-generator of claim 13, wherein the terminal board overall length is at least 15.250 cm (6.004 inches).

19. A method of installing a terminal assembly, the method comprising:

mounting a terminal board with a plurality of terminals and a plurality of barriers to a housing, the terminal board with a ratio of length to barrier spacing of at least 5.124;

1;

aligning a terminal block cover over the terminal board to cover terminals on the terminal board; and

securing the terminal block cover to the terminal board.

20. The method of claim 19, wherein the step of aligning the terminal block cover over the terminal board further comprises:

aligning a plurality of barriers extending from the terminal board cover with each the plurality of barriers extending from the terminal board.
