## Abstract

A mounting assembly for electro-mechanically connecting an electrically-powered device to a structure includes a housing, a first printed circuit board, an adapter, and a second printed circuit board. The housing has a shape defining a front opening and a first mating structure. The first printed circuit board is located within the housing and has a first plurality of electrical contacts facing the front opening. The adapter is attachable to the device and has a second mating structure that removably engages with the first mating structure of the housing. The second printed circuit board is coupled with the adapter and has a second plurality of electrical contacts exposed on its back surface to electrically connect to the first plurality of electrical contacts when the first mating structure of the housing engages with the second mating structure of the adapter.

## Claims

### Claim 1

A mounting assembly for an electrically-powered device, comprising:
a mounting plate having
a back surface configured to abut a mounting surface of a supporting structure to which the device is to be mounted, and
a front surface opposite the back surface;
a housing having
a back cover configured to attach to the front surface of the mounting plate,
a first interior surface forming a cavity and a first mating structure, and
a front opening;
a first printed circuit board located within the cavity of the housing and having a first plurality of electrical contacts facing the front opening of the housing;
an adapter including
an adapter back-end having an exterior surface configured to fit within the front opening and defining a second mating structure configured to engage with the first mating structure, and
an adapter front-end defining a front-end interior surface having a forward opening that mechanically couples to the device; and
a second printed circuit board located at the adapter back-end and having a second plurality of electrical contacts abutting the first plurality of electrical contacts, the first printed circuit board being electrically coupled to the second printed circuit board when the second mating structure engages with the first mating structure.

### Claim 2 (depends on 1)

The mounting assembly of claim 1, the forward opening of the adapter comprising a ball socket.

### Claim 3 (depends on 1)

The mounting assembly of claim 1, the first mating structure of the housing being a channel, the second mating structure of the adapter having at least one post extending radially outward from the exterior surface of the adapter and configured to engage with the channel.

### Claim 4 (depends on 3)

The mounting assembly of claim 3, the at least one post being a plurality of posts evenly spaced in a circumferential direction about the adapter.

### Claim 5 (depends on 3)

The mounting assembly of claim 3, the channel and the at least one post being configured such that the adapter is rotatable from a disengaged position, with respect to the housing, to a fully engaged position within the front opening of the housing with at most a half turn of the adapter relative to the housing.

### Claim 6 (depends on 5)

The mounting assembly of claim 5, the adapter being rotatable from the disengaged position to the fully engaged position with at most a quarter turn of the adapter relative to the housing.

### Claim 7 (depends on 1)
