Electrical assembly enclosure

1. An electrical assembly comprising:

a housing with a cavity sized to retain electrical components, and an opening to the cavity;

wherein the housing is formed from a material that shields from electromagnetic interference;

a cover sized to enclose the opening;

wherein the cover is formed from a material that shields from electromagnetic interference;

a plurality of mechanical retainers formed along a perimeter of the housing opening or the cover to be mechanically, plastically deformed into engagement with the housing or the cover to affix the cover to the housing so that the plurality of mechanical retainers is tamper proof and to avoid inadvertent disassembly of the cover from the housing; and

a seal provided between the cover and the housing;

wherein the cover further comprises:

a lid to engage the opening of the housing, and

a flange extending from the lid to enclose the seal and a distal perimeter of the housing and to shield the seal from electromagnetic interference; and

wherein the plurality of mechanical retainers extends from the flange.

2. The electrical assembly of claim 1 wherein one of the housing and the cover is provided with a series of receptacles formed about the perimeter.

3. The electrical assembly of claim 2 , wherein the series of receptacles are formed laterally around the perimeter of the housing and are spaced incrementally.

4. The electrical assembly of claim 2 , wherein the series of receptacles have a blind depth and a limited height.

5. The electrical assembly of claim 2 wherein one of the housing and the cover is provided with a series of retainers formed about the perimeter and oriented to align with the series of receptacles to be deformed into the series of receptacles.

6. The electrical assembly of claim 5 wherein no threaded fasteners attach the cover to the housing.

7. The electrical assembly of claim 1 wherein the housing is formed from an aluminum material that shields from electromagnetic interference; and

wherein the cover is formed from an aluminum material that shields from electromagnetic interference.

8. The electrical assembly of claim 1 wherein the cover and the housing shield from electromagnetic interference greater than the seal.

9. The electrical assembly of claim 1

wherein a notch is formed in the flange on each lateral side of each of the plurality of mechanical retainers to permit deformation of each of each of the plurality of mechanical retainers without deforming the flange.

10. A method for assembling the electrical assembly of claim 1 comprising:

providing the housing;

installing electrical components in the housing cavity;

placing the cover on the opening of the housing; and

plastically deforming the mechanical retainers.

11. The method of claim 10 further comprising:

providing the seal about the perimeter of the housing; and

pressing the cover against the housing to partially compress the seal while deforming the plurality of mechanical retainers.

12. The method of claim 10 further comprising:

casting the housing from an aluminum material that shields from electromagnetic interference; and

forming the cover from an aluminum material that shields from electromagnetic interference.

13. The method of claim 12 further comprising:

forming the housing with a plurality of receptacles about the perimeter of the cavity;

forming the cover with the plurality of mechanical retainers about the perimeter aligned with the plurality of receptacles; and

deforming the plurality of mechanical retainers into the plurality of receptacles.

14. An electrical assembly assembled by the method of claim 10 .

15. An electrical assembly comprising:

a housing cast from an aluminum material that shields from electromagnetic interference, with a cavity, an opening, and a series of receptacles formed laterally about a perimeter of the opening to a blind depth;

electrical components housed within the cavity;

a seal oriented about the perimeter of the opening;

a cover formed from an aluminum sheet material that shields from electromagnetic interference, and sized to enclose the opening and the seal to shield the seal from electromagnetic interference; and

a plurality of mechanical retainers formed about a perimeter of the cover and sized to align with the series of receptacles, to be mechanically deformed into the series of receptacles to affix and retain the cover to the housing; and

wherein the plurality of mechanical retainers is plastically deformed into the series of receptacles to affix and retain the cover to the housing so that the plurality of mechanical retainers is tamper proof and to avoid inadvertent disassembly of the cover from the housing.

16. The electrical assembly of claim 15 , wherein the electrical components comprise an onboard vehicle charger;

wherein no threaded fasteners attach the cover to the housing; and

wherein the seal does not shield from electromagnetic interference.
