Abstract

An electronics housing assembly is provided. The assembly includes an electronics housing defining an internal cavity. The electronics housing defines an outer side, and the electronics housing having portions defining a vent hole therein. The vent hole extends through the outer side. A sealing element is disposed adjacent to the electronics housing and contacting the outer side. The sealing element covers the vent hole. A method for sealing an electronics housing assembly is also provided.

First claim

What is claimed is:

1. An electronics housing assembly comprising:
an electronics housing defining an internal cavity, the electronics housing having an outer side, the electronics housing having portions defining a vent hole therein, the vent hole extending through the outer side;
a sealing element disposed adjacent to the electronics housing and contacting the outer side, the sealing element covering the vent hole, wherein the sealing element has a first side that is disposed adjacent to and contacting the outer side of the electronics housing, the first side having an adhesive material disposed thereon, the adhesive material affixing the sealing element to the electronics housing;
a label disposed adjacent to and contacting the outer side of the electronics housing, the sealing element defining a second side disposed opposite the first side, the label disposed adjacent to and contacting the second side, the label at least substantially covering the second side of the sealing element; and
the adhesive material being a first adhesive material, the electronics housing assembly further comprising a second adhesive material disposed on an underside of the label, the second adhesive material affixing the label to the sealing element and the outer side of the electronics housing.

2. The electronics housing assembly of claim 1 , wherein the sealing element is formed from one of polyester and aluminum.

3. The electronics housing assembly of claim 2 , wherein the electronics housing is stamped of one of aluminum and steel.

4. The electronics housing assembly of claim 2 , the sealing element being substantially flat.

5. The electronics housing assembly of claim 4 , the label being substantially flat.

6. The electronics housing assembly of claim 1 , the electronics housing assembly being an engine control unit, the electronics housing assembly further comprising a printed circuit board disposed in the internal cavity.

7. The electronics housing assembly of claim 6 , the electronics housing comprising a first enclosure portion disposed adjacent to a second enclosure portion, the first and second enclosure portions being fixed together and defining the internal cavity.

8. An engine control unit comprising:
a housing defining an internal cavity, the housing having an outer side, the housing having portions defining a vent hole therein, the vent hole extending through the outer side;
a printed circuit board disposed in the inner cavity of the housing;
a sealing element disposed adjacent to the housing and contacting the outer side, the sealing element covering the vent hole, the sealing element having a first side that is disposed adjacent to and contacting the outer side of the housing, the first side having an adhesive material disposed thereon, the adhesive material affixing the sealing element to the outer side of the housing;
a label disposed adjacent to and contacting the outer side of the housing, the sealing element defining a second side disposed opposite the first side, the label disposed adjacent to and contacting the second side, the label at least substantially covering the second side of the sealing element; and
the adhesive material being a first adhesive material, the engine control unit further comprising a second adhesive material disposed on an underside of the label, the second adhesive material affixing the label to the sealing element and the outer side of the electronics housing.

9. The engine control unit of claim 8 , wherein the sealing element is formed of one of polyester and aluminum.

10. The engine control unit of claim 9 , wherein the housing is stamped from one of aluminum and steel.

11. The engine control unit of claim 10 , the sealing element being substantially flat.

12. The engine control unit of claim 11 , the label being substantially flat.

13. A method for sealing an electronics housing assembly, the method comprising the steps of:
providing an electronics housing defining an internal cavity, the electronics housing having an outer side, the electronics housing having portions defining a vent hole therein, the vent hole extending through the outer side;
using an adhesive material to affix a sealing element over the vent hole and contacting the outer side; and
the adhesive material being a first adhesive material, using a second adhesive material to affix a label to the outer side of the electronics housing and to the sealing element.

14. The method of claim 13 , further comprising forming the sealing element from one of polyester and aluminum.

15. The method of claim 14 , further comprising stamping the electronics housing from one of aluminum and steel.

16. The method of claim 15 , further comprising disposed a printed circuit board in the inner cavity.
