Systems and methods for covering access ports

1. An access port cover system, comprising:

a housing defining an interior region inside of the housing and an exterior region outside of the housing;

an access port disposed on an exterior wall of the housing through which access to an item in the interior region from the exterior region is provided;

a cover inhibiting access through the access port from the exterior region to the interior region; and

a fastener connectable to the exterior wall of the housing and the cover, the fastener having an actuation portion for disconnecting the housing and the cover to permit access through the access port from the exterior region to the interior region, the actuation portion disposed in the interior region and being inaccessible from the exterior region when the fastener is connected to the exterior wall of the housing and the cover.

2. The system of claim 1 , wherein the actuation portion of the fastener is accessible from the interior region.

3. The system of claim 1 , wherein the actuation portion is inaccessible from the exterior region without disassembling or damaging the system.

4. The system of claim 1 , wherein the actuation portion is configured for being engaged with a tool.

5. The system of claim 1 , wherein the housing comprises a portion of a hybrid vehicle.

6. The system of claim 1 , wherein the housing comprises a portion of a hybrid vehicle powertrain.

7. The system of claim 1 , wherein the fastener includes a securing portion and the cover includes a fastener engagement portion, the securing portion and the fastener engagement portion engageable for securing the cover to the housing.

8. The system of claim 7 , wherein the securing portion and fastener engagement portion comprise interengageable threads.

9. The system of claim 1 , further comprising:

an external fastener optionally connectable to the housing and the cover, the external fastener having an actuation portion for disconnecting the housing and the cover, the external fastener actuation portion being accessible from the exterior region when the fastener is connected to the housing and the cover.

10. The system of claim 1 , wherein the fastener is not part of the cover and is not part of the housing.

11. The system of claim 1 , wherein the fastener comprises a portion of the cover, a portion of the housing, or a portion of the cover and a portion of the housing.

12. The system of claim 1 , wherein the access port is covered by the cover.

13. The system of claim 1 , wherein the cover has an interior side facing the interior region and an exterior side facing away from the housing.

14. The system of claim 13 , wherein the actuation portion is disposed on the interior side of the cover.

15. A system, comprising:

a housing for an item having operational and nonoperational states, the housing including an access port disposed on an exterior wall of the housing through which the item may be accessed from the exterior of the housing;

a cover connectable to the housing;

a fastener configured and sized to connect the cover to the housing in a position that inhibits access to the item from the exterior of the housing through the access port, the fastener including an actuation portion for connecting and disconnecting the cover and the housing, the actuation portion being inaccessible from the exterior wall of the housing to disconnect the cover and the housing from the exterior of the housing when the fastener, the cover and the housing are connected and the item is in an operational state.

16. The system of claim 15 , wherein the fastener is accessible from the interior of the housing.

17. The system of claim 15 , wherein the item is a high voltage electrical component connectable to the housing; and

further comprising a hybrid vehicle and hybrid powertrain connectable to the high voltage electrical component;

wherein the actuation portion of the fastener is inaccessible while the housing is connected to the hybrid vehicle.

18. The system of claim 15 , wherein the actuation portion of the fastener is inaccessible to disconnect the cover and the housing from the exterior of the housing without disassembling or damaging at least one the housing, the cover, and the fastener.

19. The system of claim 15 , further comprising:

an external fastener configured and sized to connect the cover to the housing, the external fastener including an actuation portion for connecting and disconnecting the cover and the housing, the external fastener actuation portion being accessible to disconnect the external fastener from at least one of the housing and the cover from the exterior of the housing when the external fastener, the cover, and the housing are connected and the item is in an operational state.

20. A method for covering an access port, comprising the steps of:

connecting a cover to an exterior wall of a housing for an item contained within the housing, in a location that inhibits access to the item through an access port in the housing from an exterior region of the housing by actuating an actuation portion of a fastener in contact with the exterior wall of the housing and the cover; and

ceasing actuation of the fastener actuation portion when the actuation portion is in a location that is inaccessible from the exterior region of the housing when the item is operational.

21. The method of claim 20 , further comprising the steps of:

securing the cover to the housing by actuating an external fastener; and

ceasing actuation of the external fastener when the actuation portion of the external fastener is in a location that is accessible from the exterior region of the housing when the item is operational.

22. The method of claim 20 , wherein the actuating of the actuation portion is from an interior region of the housing.

23. The method of claim 20 , further comprising the step of connecting the housing to a hybrid powertrain.
