Abstract

A wall mountable connector may be secured to a wall in order to provide mechanical and electrical connections to a thermostat. In some cases, the wall mountable connector and the thermostat may, in combination, be configured to permit the thermostat to attach to the wall mountable connector only when the thermostat is in a particular orientation relative to the wall mountable connector. In some cases, the wall mountable connector includes a plurality of pin terminals that are configured to accommodate a plurality of pins extending from the thermostat. The interaction between the pins and the pin terminals may provide a lock and key arrangement between the wall mountable connector and the thermostat.

First claim

What is claimed is:

1. A wall mountable connector for securing a thermostat to a wall, the wall mountable connector comprising:
a housing having a front side and a back side, the back side is configured to be mountable to a wall;
the housing defining a male portion that extends away from the back side and to the front side of the housing, the male portion is configured to extend into and be received by a recess in a back side of a thermostat;
the housing defining a field wire aperture through the back side of the housing to accommodate one or more field wires; and
a first column of pin terminals configured to accommodate a first column of pins extending from the back side of a thermostat, the first column of pin terminals being positioned on the male portion of the housing such that the first column of pin terminals only accommodates the first column of pins extending from the back side of the thermostat when the thermostat is properly oriented relative to the wall mountable connector.

2. The wall mountable connector of claim 1 , wherein the male portion of the housing is shaped to be keyed to the recess in the back side of the thermostat so as to only allow the male portion of the housing to be received by the recess in the back side of the thermostat when the thermostat is properly oriented relative to the wall mountable connector.

3. The wall mountable connector of claim 1 , further comprising:
a second column of pin terminals configured to accommodate a second column of pins extending from the back side of the thermostat, the second column of pin terminals being positioned on the male portion of the housing such that the second column of pin terminals only accommodates the second column of pins extending from the back side of the thermostat when the thermostat is properly oriented relative to the wall mountable connector.

4. The wall mountable connector of claim 3 , wherein the first column of pin terminals is parallel to and vertically aligned with the second column of pin terminals.

5. The wall mountable connector of claim 1 , wherein the male portion of the housing has a top side, bottom side, a left side and a right side, wherein the first column of pin terminals is positioned closer to top side of the male portion of the housing than the bottom side.

6. The wall mountable connector of claim 5 , wherein a top pin of the first column of pin terminals is less than about 8 millimeters from the top side of the male portion of the housing.

7. The wall mountable connector of claim 6 , wherein a bottom pin of the first column of pin terminals is less than about 18 millimeters from the bottom side of the male portion of the housing.

8. The wall mountable connector of claim 5 , wherein a top pin of the first column of pin terminals is between about 4.5 millimeters and about 6.5 millimeters from the top side of the male portion of the housing.

9. The wall mountable connector of claim 1 , wherein a bottom pin of the first column of pin terminals is between about 14.5 millimeters and about 16.5 millimeters from the bottom side of the male portion of the housing.

10. A thermostat that is configured to be mounted to a wall mountable connector, the wall mountable connector providing a mechanical connection to a wall as well as electrical connections between the thermostat and field wires exiting the wall, the thermostat comprising:
a housing having a front side and a back side;
a recess formed within the back side, the recess configured to accommodate a male portion of a wall mountable connector, the recess defining a recess back surface;
a user interface accessible from the front side of the housing;
a printed circuit board disposed within the housing and operably coupled to the user interface;
a first column of pins secured to the printed circuit board and extending through the recess back surface, the first column of pins configured to engage a corresponding first column of pin terminals of the wall mountable connector; and
the first column of pin terminals being positioned in the recess such that the first column of pins only engage the first column of pin terminals of the wall mountable connector when the thermostat is properly oriented relative to the wall mountable connector.

11. The thermostat of claim 10 , further comprising:
a second column of pins secured to the printed circuit board and extending through the recess back surface, the second column of pins configured to engage a corresponding second column of pin terminals of the wall mountable connector; and
the second column of pin terminals being positioned in the recess such that the second column of pins only engage the second column of pin terminals of the wall mountable connector when the thermostat is properly oriented relative to the wall mountable connector.

12. The thermostat of claim 11 , wherein the first column of pins is arranged to be substantially parallel to and substantially vertically aligned with the second column of pins.

13. The thermostat of claim 10 , wherein the recess in the back side of the thermostat is shaped to be keyed to the male portion of the wall mountable connector so as to only allow the male portion of the wall mountable connector to be received by the recess in the back side of the thermostat when the thermostat is properly oriented relative to the wall mountable connector.

14. The thermostat of claim 10 , further comprising a controller to operate the thermostat.

15. The thermostat of claim 10 , wherein the recess has a recess top and a recess bottom, and the first column of pins is offset closer to the recess top than to the recess bottom.

16. A thermostat that is configured to be mounted to a wall mountable connector, the wall mountable connector providing a mechanical connection to a wall as well as electrical connections between the thermostat and field wires exiting the wall, the thermostat comprising:
a housing having a front side and a back side;
a wall mountable connector recess formed within the back side, the wall mountable connector recess configured to accommodate a male portion of a wall mountable connector, the wall mountable connector recess defining a recess back surface and recess side surfaces; and
a plurality of latch features formed within the wall mountable connector recess, the plurality of latch features configured to engage a side wall of the male portion of the wall mountable connector when the wall mountable connector is fully engaged in the wall mountable connector recess, the plurality of latch features providing a mechanical connection to the wall mountable connector.

17. The thermostat of claim 16 , wherein at least some of the plurality of latch features are positioned in the recess side surfaces.

18. The thermostat of claim 16 , wherein the male portion of the wall mountable connector comprises a mounting tab extending outward from the male portion of the wall mountable connector, and the thermostat comprises a corresponding latch feature in the recess side surface to accommodate the mounting tab.

19. The thermostat of claim 18 , wherein the mounting tab is at least substantially semicircular in shape, and the corresponding latch feature is at least substantially semicircular in shape.

20. The thermostat of claim 16 , wherein the wall mountable connector recess has a substantially rectangular, square or circular profile.
