Abstract

Provided are approaches for modularized power distribution. In one approach, an apparatus may include a module extending into an interior cavity of a housing assembly through an opening formed in a base section of the housing assembly. The module may include a component grid at one end for receiving one or more components (e.g., fuses, relays, circuit breakers, diodes, etc.), and a wiring alignment cover at an opposite end operable with a terminal. The apparatus may further include a mechanical sealing element disposed along one or more surfaces of the module to provide a seal between the module and the base section defining the opening. In another approach, a plurality of modules may be disposed within a plurality of openings formed in the base section. In another approach, the apparatus may include a bracket configured to releasably connect the base section and the cover.

First claim

The invention claimed is:

1. An apparatus, comprising:
a module extending into an interior cavity of a housing assembly through an opening of a plurality of openings formed in a base section of the housing assembly, the module including a component grid; and
a mechanical sealing element disposed along a surface of the module to provide a seal between the module and the base section defining the opening, wherein the plurality of openings are separated by a framing element extending across the interior cavity.

2. The apparatus of claim 1 , further comprising a bracket coupled to the base section, the bracket releasably connecting the base section and a cover of the housing assembly.

3. The apparatus of claim 1 , further comprising a wiring alignment cover coupled to the module.

4. The apparatus of claim 3 , wherein the wiring alignment cover is disposed external to the base section.

5. The apparatus of claim 3 , the module including an alignment cover fastener releasably connecting the wiring alignment cover to the module.

6. The apparatus of claim 1 , the module including a module fastener releasably connecting the base section and the module.

7. The apparatus of claim 1 , the mechanical sealing element comprising a gasket in abutment with a ridge, the ridge extending from the surface of the module.

8. The apparatus of claim 1 , further comprising a ledge of the base section in abutment with the mechanical sealing element.

9. The apparatus of claim 1 , further comprising a plurality of modules extending into the interior cavity of the base section through the plurality of openings formed in a base wall of the base section.

10. A modular power distribution apparatus, comprising:
a housing assembly including a base section coupled to a cover;
a set of modules extending into an interior cavity of the housing assembly through a plurality of openings formed in the base section, each of the set of modules including a component grid disposed at a first end; and
a mechanical sealing element disposed along one or more sidewalls of each of the set of modules to provide a seal between each of the set of modules and the base section defining the plurality of openings, wherein the plurality of openings are separated from one another by a framing element extending across the interior cavity.

11. The modular power distribution apparatus of claim 10 , further comprising a bracket rotatably coupled to a pin of the base section, the bracket releasably connecting the base section and the cover.

12. The modular power distribution apparatus of claim 10 , further comprising a wiring alignment cover coupled to a second end of one or more of the set of modules.

13. The modular power distribution apparatus of claim 12 , wherein the wiring alignment cover is positioned external to the base section.

14. The modular power distribution apparatus of claim 12 , further comprising an alignment cover fastener disposed along the one or more sidewalls of each of the set of modules to releasably connect the wiring alignment cover to the second end of each of the set of modules.

15. The modular power distribution apparatus of claim 10 , further comprising a module fastener disposed along the one or more sidewalls of each of the set of modules to releasably connect the base section to each of the set of modules.

16. The modular power distribution apparatus of claim 10 , the mechanical sealing element including a ridge lined by a gasket, the ridge extending substantially perpendicularly from the one or more sidewalls of each of the set of modules.

17. The modular power distribution apparatus of claim 10 , the plurality of openings each defining a ledge of the base section in abutment with the mechanical sealing element.

18. A modular power system, comprising:
a housing assembly including a base section and a cover, the base section comprising:
a base wall including a plurality of openings; and
an inner wall extending substantially perpendicularly from the base wall, wherein the inner wall is releasably coupled to the cover; and

a plurality of modules extending into an interior cavity of the housing assembly through the plurality of openings in the base wall, each of the plurality of modules including:
a component grid disposed at a first end; and
a mechanical sealing element disposed along one or more sidewalls of each of the plurality of modules, the mechanical sealing element in contact with the base wall.

19. The modular power system of claim 18 , further comprising a wiring alignment cover coupled to a second end of each of the plurality of modules, wherein the wiring alignment cover is positioned external to the base section.

20. The modular power system of claim 19 , further comprising an alignment cover fastener configured to releasably connect the wiring alignment cover to each of the plurality of modules, and a module fastener configured to releasably connect the base section and each of the plurality of modules.
