Abstract: A surge protection circuit for an electronic device such as an HVAC controller. In one example, the surge protection circuit may include a first voltage clamp, a second voltage clamp, a resistor, and an output port. The first voltage clamp may provide a first clamping voltage between a power input terminal and a common terminal. The second voltage clamp may provide a second clamping voltage that is less than the first clamping voltage. The resistor may be connected in series with the second voltage clamp, and the series connected resistor and second voltage clamp may be connected in parallel with the first voltage clamp. As such, a surge current at the power input terminal may be split between the first voltage clamp and the second voltage clamp. The amount of surge current that is provided to the second voltage clamp may be set by the value of the resistor.

Abstract: An electronic assembly may have a display, a display holder, and a printed circuit board (PCB). The display may have a front side for viewing the display, a back side, and side walls extending between the front side and the back side. The display holder may have a recess for receiving at least part of the display, where the display holder may extend adjacent part of the front side of the display and adjacent at least part of the side walls of the display. The PCB may be secured relative to the display holder and adjacent the back side of the display. The PCB may be in operative communication with the display. In some cases, a spacer may be situated between the back side of the display and the PCB.

Abstract: An illustrative electronic assembly having an electrical connector therein to ground an electronic component of the electronic assembly to a grounding feature of a printed wiring assembly (PWA) of the electronic assembly. The electronic assembly may include a housing, the PWA, the electronic component and the electrical connector. The electrical connector may be a conductive and resilient extender or connector that may have a first portion connected to the PWA and a second portion extending generally away from the PWA toward the electronic component. The second portion of the electrical connector may be in mechanical and electrical contact with the electronic component.

Abstract: An electronic device may include a housing and a printed circuit board, where the housing has a front cover and a back cover that at least substantially enclose the printed circuit board. In some instances, the back cover may include an outer shell and one or more inward extending walls that extend inwardly toward the printed circuit board. In some cases, the inward extending walls, the outer shell, and the printed circuit board define two or more internal pockets within the housing. The pockets may, in some cases, separate one region of the printed circuit board from another region of the printed circuit board. In some instances, the one or more inward extending walls may be configured to provide support to a back side of the printed circuit board, which may be particularly useful when a touch screen display is mounted on a front side of the printed circuit board.

Abstract: An illustrative electronic assembly includes a housing and a wall plate, where the wall plate is releasably connectable to the housing. The housing and the wall plate may be configured such that the housing and the wall plate may be able to initially engage each other with the wall plate misaligned relative to the housing. The housing and the wall plate may be configured to guide one another into alignment as the housing and the wall plate are moved together.

Abstract: A heating, ventilation, and air conditioning (HVAC) controller may include a housing and a printed circuit board (PCB) situated within the housing. The PCB may include a battery seat region and electrical terminals for electrically connecting a battery to the PCB when the battery is positioned at the battery seat region. The housing may include an opening that may be configured to receive the battery. The battery seat region may be at least partially offset relative to the opening in the housing, but accessible via the opening. The housing may be configured to allow the battery to be inserted into the opening and then moved laterally to the battery seat region, where the battery may be at least partially covered and/or protected by the housing when at the battery seat region. In some cases, the battery may be inserted within the housing without adjusting any part of the housing.
