A grounding system for electrically connecting a first component to a second component. A connection plate has a hole and is configured to be in electrical contact with the first component. A receptacle plate is in electrical contact with the connection plate, and has a receptacle opening aligned with and larger than the hole. A pin has a first end configured to be electrically connected to the second component and an opposed second end receivable through the receptacle opening and through the hole. An electrical connector is retained in electrical contact with the pin. The electrical connector is movable along the pin and biased toward the second end, receivable in the receptacle opening and configured to be in electrical contact with a circumferential surface of the receptacle opening, and has an outer dimension greater than that of the hole so as to be prevented from passing therethrough.

The present disclosure relates to miniaturized motor assembly for use in an appliance, for example, an ice maker for a commercial or residential refrigerator. The miniaturized motor assembly includes an electric motor, such as a permanent magnet direct current (PMDC) motor, and a printed circuit board operable to control power to the electric motor, wherein the printed circuit board is connected to the motor as a component of the assembly. At least one electrically-conductive connection device acts as a terminal, providing multiple points of contact between the printed circuit board and the motor, forming both an improved, reliable mechanical connection and an effective electrical connection between the circuit board and the motor. Use of the electrically-conductive connection device of the present disclosure eliminates the need for tedious and inconsistent soldering connections, while providing multiple points of contact and improved electrical contact over other forms of connecting devices.

An approach for connecting electrical wiring between two chambers of varying temperatures is disclosed. One approach includes a first end of a wiring bundle comprising a first plurality of metal conductors; a second end of the wiring bundle comprising of equal number of metal conductors as the first end of the wiring bundle; the first end of the wiring bundle is separated by an air gap from the second end of the wiring bundle at a first temperature; and an insulator surrounding the wire bundle. Another approach includes the use of one or more SMA (shape-memory alloy) pins connecting the first end of the wiring bundle to the second end of the wiring bundle and that is separated by an air gap and a boundary plate.
