The invention refers to an electrical connection (10) comprising a bushing (12) having a geometric central axis (14), an electrical conductor (16) passing through said bushing (12) along the geometric central axis (14), and an insulating layer (18) electrically insulating said bushing (18) from said conductor (16). It is suggested that the bushing 12, the insulating layer (18) and the electric conductor (16) are pressed together, preferably during a rotary forging process, in order to achieve a mechanical cold transformation.

A shunt extends from a brush received by a brush box of a brush holder. The first end of the shunt can be connected to the brush, and the second end of the shunt can connect to the brush holder. A lever connects to a back plate of the brush holder, and the lever may reversibly and selectively rotate between a first position and a second position; the lever can have a distal portion, and the second position of the lever secures a portion of the shunt between the distal portion of the lever and another component of the brush holder. The secured portion of the shunt can restrict downward movement of the brush in the brush box, while a spring pushes downward on the brush in the brush in the brush box, to thereby fixedly position the brush in the brush box.

Example brush holder assemblies of an electric machine are disclosed. An example brush holder assembly of an electric machine includes a carbon brush including an upper surface and a lower surface opposite the upper surface. The brush holder assembly also includes one or more lead wires extending out of the carbon brush at an insertion point on the upper surface and a first cavity extending into the carbon brush from the upper surface at a location spaced away from the insertion point of the one or more lead wires and unobstructed by the one or more lead wires.

A shunt for a charging contact assembly may include an elongate elastic support substrate and a conductor disposed of the elongate elastic support substrate for transferring electrical current. A charging contact assembly may include a connector to connect to a source of electrical energy for receiving electrical current and a brush coupled with the connector for contacting a conducting surface to transfer the electrical current. The charging contact assembly may also include a shunt fixedly connected to the connector and the brush for transferring the electrical current from the connector to the brush, where the shunt includes an elongate arcuate elastic support substrate fixedly connected to the connector and the brush, and a conductor disposed of the elongate arcuate elastic support substrate and extending between the connector and the brush.

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.
