Optical sensor housing

1. A sensor housing for an optical sensor assembly, comprising:

a sensor housing body comprising

one or more support walls upstanding from a bottom portion and a substantially open top portion defining a cavity in which the optical sensor assembly is located;

at least one aperture; and

at least one engaging part projecting orthogonally from an outside surface of the sensor housing body; and

a sensor housing cover comprising:

an open central portion;

at least one integrally molded compliant flange configured to engage the at least one sensor housing body engaging part and to removably secure the sensor housing cover to the sensor housing body; and

a plurality of longitudinal ridges extending outwardly and disposed substantially along a length of the sensor housing cover;

wherein an inner portion of the sensor housing cover comprises a plurality of ribs configured to secure an optical window within the aperture of the sensor housing body, and wherein the ribs are operable to collect moisture and to cause the moisture to move in a downward direction exiting the inner portion of the sensor housing cover via the open central portion.

2. The sensor housing for an optical sensor assembly of claim 1 , wherein the at least one engaging part comprises a pair of opposing engaging parts located in proximity to the aperture.

3. The sensor housing for an optical sensor assembly of claim 1 , wherein the at least one flange comprises a pair of opposing flanges located at a periphery of a top portion of the sensor housing cover.

4. The sensor housing for an optical sensor assembly of claim 1 , wherein the at least one flange comprises a generally C-shaped member.

5. The sensor housing for an optical sensor assembly of claim 1 , wherein

the at least one engaging part comprises a pair of opposing engaging parts located in proximity to the aperture; and

the at least one flange comprises a pair of opposing flanges located and configured to receive a portion of the engaging parts when the sensor housing cover is secured to the sensor housing body.

6. The sensor housing for an optical sensor assembly of claim 5 , wherein the pair of opposing engaging parts and the pair of opposing flanges provide a quick-lock mechanism operable to secure the sensor housing cover to the sensor housing body without the use of a fastener.

7. The sensor housing for an optical sensor assembly of claim 5 , wherein the pair of opposing engaging parts and the pair of opposing flanges provide a quick-lock mechanism operable to secure the sensor housing cover to the sensor housing body without the use of a tool.

8. The sensor housing for an optical sensor assembly of claim 5 , wherein the pair of opposing engaging parts and the pair of opposing flanges provide a quick-lock mechanism operable to release the sensor housing cover from the sensor housing body without the use of a tool.

9. The sensor housing for an optical sensor assembly of claim 1 , wherein the at least one engaging part includes a groove for engaging the at least one flange.

10. The sensor housing for an optical sensor assembly of claim 1 , wherein the plurality of ridges comprise linear and parallel elevations forming channels therebetween.

11. The sensor housing for an optical sensor assembly of claim 1 , wherein the optical window is secured the sensor housing body by the sensor housing cover, and the optical window is configured to seal the sensor housing body aperture in alignment with the optical sensor assembly.

12. The sensor housing for an optical sensor assembly of claim 11 , wherein the optical window and the sensor housing body form a unitary part.

13. The sensor housing for an optical sensor assembly of claim 11 , wherein a surface of the optical window comprises a material, coating, film, or layer having hydrophobic properties.

14. The sensor housing for an optical sensor assembly of claim 11 , wherein a surface of the optical window comprises a material, coating, film, or layer having hydrophilic properties.
