Ratcheting cover for sensor housing
View Patent ↗A mountable sensor assembly with a ratcheting cover attachment is provided. The sensor assembly may include a sensor circuit, a sensor housing, and a cover. The sensor housing may have walls that define a cavity with an opening for receiving the sensor circuit. The cover may be configured to extend over and seal the opening. The cover may be configured to interface with the walls through a ratcheting mechanism. The ratcheting mechanism may include a plurality of flexible latching fingers that engage solid ridges. The flexible latching fingers have one attached end and one unattached end, such that the flexible latching fingers deflect from the attached end.
1. A mountable sensor assembly comprising:
a sensor circuit;
a sensor housing having walls that define a cavity with an opening for receiving the sensor circuit; and
a cover configured to enclose and seal the opening, the cover being configured to interface with the walls of the housing through a ratcheting mechanism.
2. The assembly of claim 1 , wherein the ratcheting mechanism includes flexible latching fingers that engage solid ridges.
3. The assembly of claim 2 , wherein the flexible latching fingers have one attached end and one unattached end such that the flexible latching fingers deflect from the attached end.
4. The assembly of claim 1 , wherein the cover comprises flexible latching fingers that engage solid ridges on the walls of the housing.
5. The assembly of claim 1 , wherein the cover comprises flexible latching fingers on an inside surface of the cover that engage solid ridges in an outside surface the walls of the housing.
6. The assembly of claim 1 , wherein the cover comprises flexible latching fingers on an outside surface of the cover that engage solid ridges in an inside surface the walls of the housing.
7. The assembly of claim 1 , wherein the walls comprise flexible latching fingers that engage solid ridges in the cover.
8. The assembly of claim 1 , wherein the walls comprise flexible latching fingers on an inside surface of the walls that engage solid ridges in an outside surface of the cover.
9. The assembly of claim 1 , wherein the walls comprise flexible latching fingers on an outside surface of the walls that engage solid ridges in an inside surface of the cover.
10. The assembly of claim 1 , wherein the ratcheting mechanism comprises a first set of flexible latching fingers that are offset from a second set of flexible latching fingers.
11. The assembly of claim 10 , wherein the first set of flexible latching fingers form a first set of columns and the second set of flexible latching fingers form a second set of columns, rows in the first set of columns being offset from rows in the second set of columns.
12. The assembly of claim 11 , wherein the rows in the first set of columns have a different frequency than rows in the second set of columns.
13. The assembly of claim 1 , wherein the ratcheting mechanism comprises a first set of solid ridges that are offset from a second set of solid ridges.
14. The assembly of claim 13 , wherein the first set of solid ridges form a first set of columns and the second set of solid ridges form a second set of columns, rows in the first set of columns being offset from rows in the second set of columns.
15. The assembly of claim 14 , wherein the rows in the first set of columns have a different frequency than rows in the second set of columns.
16. A mountable sensor assembly comprising:
a sensor circuit;
a sensor housing having walls that define a cavity with an opening for receiving the sensor circuit; and
a cover configured to enclose and seal the opening, the cover being configured to interface with the walls through a ratcheting mechanism, the ratcheting mechanism includes flexible latching fingers that engage solid ridges, the flexible latching fingers have one attached end and one unattached end such that the flexible latching fingers deflect from the attached end as they pass over the apexes of the solid ridges, and then engage respective retention surfaces of the solid ridges to prevent the fingers from reversing over the solid ridges.
17. The assembly of claim 16 , wherein the cover comprises flexible latching fingers that engage solid ridges in the walls of the housing.
18. The assembly of claim 16 , wherein the walls comprise flexible latching fingers that engage solid ridges in the cover.
19. The assembly of claim 16 , wherein the ratcheting mechanism comprises a first set of flexible latching fingers that are offset from a second set of flexible latching fingers.
20. A mountable sensor assembly comprising:
a sensor circuit;
a sensor housing having walls that define a cavity with an opening for receiving the sensor circuit; and
a cover configured to enclose and seal the opening, the cover being configured to interface with the walls through a ratcheting mechanism, the ratcheting mechanism including flexible latching fingers that engage solid ridges, the flexible latching fingers having one attached end and one unattached end such that the flexible latching fingers deflect from the attached end, the flexible latching fingers forming a first set of columns and a second set of columns, rows of the first set of columns being offset from rows of the second set of columns.
