Dynamoelectric machine grommet

1. A dynamoelectric machine grommet, comprising:

a body portion of the grommet sealably engagable with an opening in a housing of a dynamoelectric machine;

at least one projection extending from the body portion and receptive to a conductor and providing electrical insulation thereto;

wherein a cross section of the at least one projection is opened on at least one side to receive the conductor;

the cross section of the at least one projection is substantially “C” shaped, forming a recessed portion in the at least one substantially “C” shaped projection;

at least one portion of the open side of the cross section of the at least one substantially “C” shaped projection is smaller than the axial thickness of the conductor;

wherein the at least one portion of the at least one projection that is smaller than an axial thickness of the conductor is near an end of the at least one projection opposite an end of the at least one projection that is near the body portion, and wherein the recessed portion in the at least one substantially “C” shaped projection continues in an uninterrupted fashion across the body portion.

2. The grommet of claim 1 , further comprising:

an aperture through the body portion receptive to and sealable to a conductor protruding therethrough.

3. The grommet of claim 2 , wherein the aperture is slit shaped to seal to the conductor.

4. The grommet of claim 2 , wherein the aperture extends from an inside of the dynamoelectric machine to an outside of the dynamoelectric machine.

5. The grommet of claim 2 , wherein the body portion includes larger areas on portions at greater and lesser radial dimensions than a portion with a radial dimension substantially coincident with a surface of the housing of the machine.

6. The grommet of claim 1 , wherein the grommet is electrically nonconductive.

7. The grommet of claim 1 , wherein the grommet is elastic to enhance sealability and provide flexibility for assembly of the grommet to the dynamoelectric machine.

8. The grommet of claim 1 , wherein the at least one open side of the cross section of the at least one projection faces radially inwardly.

9. The grommet of claim 1 , wherein the at least one projection is shaped to match a shape of the conductor.

10. The grommet of claim 1 , wherein the shape of the at least one projection is arcuate.

11. The grommet of claim 1 , wherein two projections extend from the body portion in substantially opposite directions.

12. The grommet of claim 1 , wherein the grommet is made of an elastomeric material.

13. A starter motor insulating grommet, comprising:

a flanged portion sealable with an opening in a housing of a starter motor and sealable with a bus bar in a bore therethrough;

a pair of projecting members extending from the flanged portion receptive of a bus bar, the projecting members being electrically insulative to a portion of the bus bar;

wherein a cross section of the pair of projecting members is opened on at least one side to receive the bus bar;

the cross section of the pair of projecting members is substantially “C” shaped, forming a recessed portion in the pair of substantially “C” shaped projecting members;

at least one portion of the open side of the cross section in each projecting member of the pair of substantially “C” shaped projecting members is smaller than the axial thickness of the bus bar;

wherein the at least one portion in each projecting member of the pair of substantially “C” shaped projecting members that is smaller than an axial thickness of the bus bar is near an end of the projecting member opposite an end of the projecting member that is near the flanged portion, and wherein the recessed portion in each projecting member of the pair of substantially “C” shaped projecting members continues in an uninterrupted fashion across the flanged portion.

14. The staffer motor insulating grommet of claim 13 , wherein the projecting members are electrically insulative to a bus bar over the entire length of the projecting members.
