Abstract

A wall mountable connector is used for securing a thermostat to a wall. The wall mountable connector provides an electrical connection between a plurality of field wires of an HVAC system and corresponding terminals of a removably mounted thermostat. The wall mountable connector includes a plurality of mounting features that are configured to provide good securement of the wall mountable connector relative to the wall, and in some instances facilitate aligning at least one of the mounting feature of the wall mountable connector with a stud within the wall.

Claims

1. A wall mountable connector for securing a thermostat to a wall, the wall mountable connector comprising:

a housing having a front side, a back side, a left side and a right side, the back side is configured to be mountable toward the wall;

the housing defining a field wire receiving cavity;

the housing defining a field wire aperture through the back side of the housing and into the field wire receiving cavity, the field wire aperture configured to accommodate one or more field wires;

a first wiring connection block positioned along a left side of the field wire receiving cavity, the first wiring connection block configured to electrically connect to one or more field wires;

a first column of pin terminals positioned along the left side of the field wire receiving cavity and adjacent the first wiring connection block, the first column of pin terminals configured to accept a corresponding first column of pins of the thermostat;

a second wiring connection block positioned along a right side of the field wire receiving cavity, the second wiring connection block configured to electrically connect to one or more field wires;

a second column of pin terminals positioned along the right side of the field wire receiving cavity and adjacent the second wiring connection block, the second column of pin terminals configured to accept a corresponding second column of pins of the thermostat;

an upper mounting feature disposed in an upper portion of the wall mountable connector;

a first lower mounting feature disposed in a lower portion of the wall mountable connector, the first lower mounting feature offset to the left of the upper mounting feature; and

a second lower mounting feature disposed in the lower portion of the wall mountable connector, the second lower mounting feature offset to the right of the upper mounting feature.

2. The wall mountable connector of claim 1, wherein the upper mounting feature comprises a vertically aligned elongate slot.

3. The wall mountable connector of claim 2, wherein the first lower mounting feature comprises an elongate slot oriented diagonally and to the left relative to the vertically aligned elongate slot.

4. The wall mountable connector of claim 3, wherein the second lower mounting feature comprises an elongate slot oriented diagonally and to the right relative to the vertically aligned elongate slot.

5. The wall mountable connector of claim 1, wherein the first lower mounting feature is disposed near a lower left corner of the wall mountable connector, and the second lower mounting feature is disposed near a lower right corner of the wall mountable connector.

6. The wall mountable connector of claim 1, wherein the upper mounting feature, the first lower mounting feature and/or the second lower mounting feature comprise an aperture with a reduced height shoulder surrounding the aperture to accommodate a fastener head.

7. A wall mountable connector for securing a thermostat to a wall, the wall mountable connector comprising:

a housing having a front side, a back side, a left side and a right side, and a top side, the back side is configured to be mountable toward the wall;

the housing defining a field wire receiving cavity;

the housing defining a field wire aperture through the back side of the housing and into the field wire receiving cavity, the field wire aperture configured to accommodate one or more field wires;

a first wiring connection block positioned along a left side of the field wire receiving cavity, the first wiring connection block configured to electrically connect to one or more field wires;

a second wiring connection block positioned along a right side of the field wire receiving cavity, the second wiring connection block configured to electrically connect to one or more field wires;

a first mounting feature and a second mounting feature, wherein the first mounting feature is offset horizontally to the left of the field wire aperture, and the second mounting feature is offset horizontally to the right of the field wire aperture;

a third mounting feature offset vertically from the first mounting feature and/or the second mounting feature; and

a mounting tab extending vertically from the top side of the housing and above the field wire receiving cavity, wherein the mounting tab including the third mounting feature.

8. The wall mountable connector of claim 7, wherein the first mounting feature is offset to the left of the field wire aperture by no more than 1.5 inches, and the second mounting feature is offset to the right of the field wire aperture by no more than 1.5 inches.

9. The wall mountable connector of claim 7, wherein the third mounting feature is positioned between the first mounting feature and the second mounting feature, but vertically offset from the first mounting feature and/or the second mounting feature.

10. The wall mountable connector of claim 7, wherein the first mounting feature and the second mounting feature are located along a lower edge of the wall mountable connector, and the third mounting feature is located along an upper edge of the wall mountable connector.

11. The wall mountable connector of claim 10, wherein the first mounting feature, the second mounting feature and the third mounting feature are located at the vertices of an isosceles triangle.

12. The wall mountable connector of claim 10, wherein the first mounting feature, the second mounting feature and the third mounting feature are located at the vertices of an equilateral triangle.

13. The wall mountable connector of claim 7, wherein the third mounting feature comprises a vertically aligned elongate slot.

14. The wall mountable connector of claim 13, wherein the first mounting feature comprises an elongate slot oriented diagonally and to the left relative to the vertically aligned elongate slot.

15. The wall mountable connector of claim 14, wherein the second mounting feature comprises an elongate slot oriented diagonally and to the right relative to the vertically aligned elongate slot.

16. The wall mountable connector claim 7, wherein the first mounting feature is disposed near a lower left corner of the wall mountable connector, and the second mounting feature is disposed near a lower right corner of the wall mountable connector.

17. The wall mountable connector of claim 16, wherein the third mounting feature is disposed near an upper edge of the wall mountable connector.

18. A wall mountable connector for securing a thermostat to a wall, the wall mountable connector comprising:

a housing having a front side, a back side, a left side and a right side, the back side is configured to be mountable toward the wall;

the housing defining a field wire aperture through the back side of the housing to accommodate one or more field wires;

a first mounting feature and a second mounting feature, wherein the first mounting feature is offset horizontally to the left of a left side of the field wire aperture, and the second mounting feature is offset horizontally to the right of the field wire aperture; and

a door that is movable between an open position in which the field wire receiving cavity is exposed and a closed position in which the door covers the field wire receiving cavity but does not cover the first mounting feature or the second mounting feature.
