Abstract

An adaptor plate includes a front plate that is configured to span across at least a portion of a front of an electrical junction box and includes one or more adaptor plate mounting features configured to align with corresponding mounting features of the electrical junction box. A DIN rail engagement portion extends backward from the front plate (and into the junction box) and is configured to fit at least partially into an elongated DIN rail mounting recess of a DIN rail device. In some cases, a first mounting slot is disposed within a first side of the DIN rail engagement portion for receiving a first mounting latch of the DIN rail device, and a second mounting slot is disposed within a second side of the DIN rail engagement portion for receiving a second mounting latch of the DIN rail device.

First claim

1 - 10 . (canceled)

11 . An adaptor plate for securing a DIN rail device inside of an electrical junction box, the adaptor plate securable to a front of the electrical junction box with the DIN rail device disposed within the electrical junction box, the adaptor plate comprising:
a front plate configured to span across at least a portion of a front of the electrical junction box, the front plate including one or more adaptor plate mounting features located relative to the front plate such that the one or more adaptor plate mounting features align with corresponding mounting features on the electrical junction box; a DIN rail engagement portion extending backward from the front plate and configured to fit at least partially into an elongated DIN rail mounting recess of a DIN rail device, the DIN rail engagement portion having a first side spaced from a second side, wherein the first side is configured to extend lengthwise along a first side of the DIN rail mounting recess of the DIN rail device, and wherein the second side is configured to extend lengthwise along a second side of the DIN rail mounting recess of the DIN rail device; a first mounting slot disposed within the first side of the DIN rail engagement portion for receiving a first mounting latch of the DIN rail device that extends into the DIN rail mounting recess from the first side of the DIN rail mounting recess; and a second mounting slot disposed within the second side of the DIN rail engagement portion for receiving a second mounting latch of the DIN rail device that extends into the DIN rail mounting recess from the second side of the DIN rail mounting recess.

12 . The adaptor plate of claim 11 , further comprising a third mounting slot disposed within the first side of the DIN rail engagement portion for receiving a third mounting latch of the DIN rail device that extends into the DIN rail mounting recess from the first side of the DIN rail mounting recess.

13 . The adaptor plate of claim 12 , wherein the first mounting slot and the second mounting slot are elongated slots extending lengthwise relative to the DIN rail mounting recess.

14 . The adaptor plate of claim 11 , wherein the adaptor plate mounting features comprise elongated slots that extends at an acute angle relative to either the first side and the second side of the DIN rail engagement portion.

15 . The adaptor plate of claim 11 , wherein the adaptor plate is configured to be secured to a double gang electrical junction box, a triple gang electrical junction box or a larger electrical junction box.

16 . An assembly for mounting a DIN rail device relative to an electrical junction box, the assembly comprising:
a DIN rail device configured to fit within the electrical junction box, the DIN rail device comprising:
a housing, the housing including a rear portion;
a recess formed within the rear portion of the housing and configured for
securement to a DIN rail, the recess including a stationary mounting latch and a movable mounting latch, the movable mounting latch positioned across the recess and offset from the stationary mounting latch; and,

an adaptor plate comprising:
a front plate configured to span across at least a portion of a front of the
electrical junction box, the front plate including one or more adaptor plate mounting features located relative to the front plate such that the one or more adaptor plate mounting features align with corresponding mounting features of the electrical junction box; and,

a DIN rail engagement portion extending backward from the front plate
and configured to fit into the recess of the DIN rail device, the DIN rail engagement portion including a first mounting slot for receiving at least part of the stationary mounting latch and a second mounting slot for receiving at least part of the movable mounting latch.

17 . The assembly of claim 16 , wherein the DIN rail engagement portion has a rectilinear profile with at least a first long side and a second long side, with the first mounting slot is disposed within the first long side and the second mounting slot is disposed within the second long side.

18 . The assembly of claim 17 , wherein the first long side of the DIN rail engagement portion comprises a first side wall perpendicular to the front plate, and the first mounting slot is formed within the first side wall.

19 . The assembly of claim 17 , wherein the second long side of the DIN rail engagement portion comprises a second side wall perpendicular to the front plate, and the second mounting slot is formed within the second side wall.

20 . The assembly of claim 16 , further comprising a cover plate configured to extend over the adaptor plate and to be secured relative to the electrical junction box.
