Abstract: A charging gun having excellent heat conduction and dissipation performance, comprising a gun body, terminals, insulated sleeves, and a metal heat dissipation member; rear end portions of the terminals pass through the sleeves, the metal heat dissipation member is opened with mounting holes for inserting and fixing the sleeves, and the metal heat dissipation member is fixed to the gun body. The present solution prevents short circuiting by using metal heat dissipation member as a body for fixing the terminals and by using insulated sleeves to separate metal heat dissipation member from the terminals. Large ceramic members that conventionally fix terminals are removed, thus preventing the difficulty wherein a ceramic member having a large volume tends to break when a hole is opened thereon. Processes for processing the sleeves and opening the mounting holes on the metal heat dissipation member are all convenient, having a low level of machining difficulty.

Abstract: A controller for use in a climate control system. The controller, which may be a wireless-enabled thermostat, includes a power stealing circuit configured to steal power from a first load that is in an “on” mode and from a second load that is in an “off” mode. The stealing is performed from the first and second loads at the same time. Sufficient power can be stolen to support substantially constant operation of a transceiver of the controller.

Abstract: Disclosed are exemplary embodiments of systems and methods for dynamically displaying informational content on a controller display. In an exemplary embodiment, a climate control system controller generally includes a display and at least one sensor configured to detect a user within a vicinity of the climate control system controller. A distance is determined between the climate control system controller and the detected user. Based on the determined distance, a first or a second display component arrangement is shown on the display. Informational content of the second display component arrangement differs at least in part from informational content of the first display component arrangement.
