Abstract

An adapter plate may be used to secure a wall mountable connector to a junction box by engaging mounting features of the wall mountable connector. In some cases, the wall mountable connector may be directly secured to a wall via fasteners that extend through the same mounting features of the wall mountable connector. In some cases, the adapter plate may be configured such that the wall mountable connector can be secured to the adapter plate simply by pressing the wall mountable connector into position on the adapter plate, where mounting latches of the adapter plate engage the mounting apertures of the wall mountable connector. The wall mountable connector may be an HVAC wall mountable connector that provides an electrical connection between a plurality of field wires of an HVAC system and corresponding terminals of a removably mounted thermostat.

Claims

1. An adapter plate for securing a wall mountable connector to a junction box, wherein the wall mountable connector is configured to releasably secure a controller, which includes a housing that extends along a front side and a back side of the controller, to the wall mountable connector and provide electrical connections between the controller and equipment that is to be controlled by the controller, the adapter plate comprising:

an adapter plate substrate having one or more mounting features;

a field wire opening defined by the adapter plate substrate that permits one or more field wires to pass from the junction box to the wall mountable connector;

the one or more mounting features of the adapter plate substrate are configured to releaseably secure the wall mountable connector to the adapter plate substrate; and

a plurality of junction box mounting openings defined by the adapter plate substrate, each of the plurality of junction box mounting openings configured to receive a securement for securing the adapter plate substrate to the junction box.

2. The adapter plate of claim 1, wherein the plurality of junction box mounting openings comprise at least two junction box mounting openings that are configured to mount the adapter plate substrate to a single junction box situated in a vertical orientation.

3. The adapter plate of claim 2, wherein the plurality of junction box mounting openings comprise at least two junction box mounting openings that are configured to mount the adapter plate substrate to a single junction box situated in a horizontal orientation.

4. The adapter plate of claim 2, wherein the plurality of junction box mounting openings comprise at least two junction box mounting openings that are configured to mount the adapter plate substrate to a double junction box.

5. The adapter plate of claim 1, wherein the one or more mounting features of the adapter plate substrate are configured to permit the wall mountable connector to be secured to the adapter plate substrate by pressing the wall mountable connector against the adapter plate substrate such that each of the one or more mounting features of the adapter plate substrate engage a corresponding feature of the wall mountable connector.

6. The adapter plate of claim 5, wherein at least one of the mounting features of the adapter plate substrate include a pair of crush ribs, and a latch that extends through a hole in the wall mountable connector.

7. The adapter plate of claim 6, wherein the pair of crush ribs are configured to deform as they are pressed at least partially into the hole in the wall mountable connector.

8. The adapter plate of claim 5, wherein the adapter plate substrate further comprises one or more alignment features that are configured to align the wall mountable connector with the adapter plate substrate.

9. The adapter plate of claim 1, wherein the one or more mounting features of the adapter plate substrate comprises:

an upper mounting latch;

a first lower mounting latch located lower than the upper mounting latch and offset to the left of the upper mounting latch;

a second lower mounting latch located lower than the upper mounting latch and offset to the right of the upper mounting latch; and

wherein the wall mountable connector comprises three mounting openings positioned to align with the upper mounting latch, the first lower mounting latch and the second lower mounting latch, respectively.

10. An adapter plate for securing a wall mountable connector relative to a wall, the adapter plate comprising:

an adapter plate substrate;

a field wire opening defined by the adapter plate substrate that permits one or more field wires to pass from the wall to the wall mountable connector;

a plurality of mounting openings defined by the adapter plate substrate, each of the plurality of mounting openings configured to receive a securement for securing the adapter plate substrate relative to the wall;

a plurality of mounting latches extending from the adapter plate substrate for latching the wall mountable connector to the adapter plate substrate, the plurality of mounting latches comprising;

a first mounting latch offset horizontally to the left of a left side of the field wire opening;

a second mounting latch offset horizontally to the right of a right side of the field wire opening; and

a third mounting latch offset vertically from the first mounting latch and/or the second mounting latch.

11. The adapter plate of claim 10, wherein at least some of the plurality of mounting openings are configured to mount the adapter plate substrate to a junction box disposed within the wall.

12. The adapter plate of claim 10, wherein the first mounting latch, the second mounting latch and the third mounting latch are configured, in combination, to engage corresponding mounting openings of the wall mountable connector to secure the wall mountable connector relative to the adapter plate substrate, and wherein the mounting openings of the w wall mountable connector are configured to receive a securement for optionally securing the wall mountable connector directly to a wall without the adapter plate.

13. The adapter plate of claim 10, wherein the first mounting latch is offset horizontally to the left of the left side of the field wire aperture by no more than 1.5 inches and the second mounting latch is offset horizontally to the right of the right side of the field wire aperture by no more than 1.5 inches.

14. The adapter plate of claim 10, wherein the third mounting latch is offset vertically from the first mounting latch or the second mounting latch by no more than 3 inches.

15. The adapter plate of claim 10, wherein the first mounting latch, the second mounting latch and the third mounting latch are located at the vertices of an isosceles triangle.

16. The adapter plate of claim 10, wherein the first mounting latch, the second mounting latch and the third mounting latch are located at the vertices of a triangle with a horizontal side of the triangle extending horizontally, the first mounting latch is disposed at a left end of the horizontal side of the triangle and the second mounting latch is disposed at a right end of the horizontal side of the triangle.

17. An adapter plate for securing a wall mountable connector relative to a wall, the adapter plate comprising:

an adapter plate substrate;

a field wire opening defined by the adapter plate substrate that permits one or more field wires to pass from the wall to the wall mountable connector;

a plurality of mounting openings defined by the adapter plate substrate, each of the plurality of mounting openings configured to receive a securement for securing the adapter plate substrate relative to the wall;

a plurality of mounting latches extending from the adapter plate substrate for latching the wall mountable connector to the adapter plate substrate, the plurality of mounting latches comprising;

a first mounting latch offset horizontally to the left of a left side of the field wire opening by no more than 1.5 inches; and

a second mounting latch offset horizontally to the right of a right side of the field wire opening by no more than 1.5 inches.
