A circular power connector that can accommodate plugs of varying diameters includes a plurality of electrical terminals that include a contact beam extending from and monolithic with base, where the contact beam includes a contact portion, and a mounting portion that extends from and monolithic with a base for mounting the terminal to a substrate. The terminals are cylindrically arranged to receive a plug. Alternatively, each electrical terminal includes a frame portion, a first contact beam extending from the frame in a first direction, and a second contact beam extending from the frame in a second direction. Multiple electrical terminals are oriented so that the first and second contact beams for one terminal extend at an angle, preferably perpendicular, to the first and second contact beams of another electrical terminal, in a still further embodiment, an electrical terminal having two halves is provided.

An ethernet bridge mounting arrangement includes a housing including a cover portion and a back portion and a wall mount. The housing is configured to be coupled with the wall mount, and the housing is rotatable relative to the wall mount about an axis that extends in a direction perpendicular to a rear surface of the housing between a first rotational orientation, where latching members extending from the housing can be received by and removed from latch openings in the wall mount, and a second rotational orientation, where the housing is prevented from being pulled away from the wall plate.

A charging system for a battery-operated machine is disclosed. The charging system includes a charging receptacle having a power connection and a signal connection, with the charging receptacle configured to receive electrical current via the power connection from a power supply plug. The charging system further includes a heat rejection element thermally coupled to the charging receptacle, a temperature sensor, and a charging controller operatively coupled to the temperature sensor and the charging receptacle. The charging controller is configured to receive a temperature signal from the temperature sensor, the temperature signal being indicative of a charging-receptacle temperature. The charging controller is further configured to transmit, via the signal connection to the connected plug, a control signal to adjust (e.g., raise or lower) the electrical current supplied to the power connection.

A powered wall plate may include a face plate comprising an opening extending through the face plate from the first surface to the rear surface. A first keyed interface may be formed at the rear surface of the face plate. An electrical receptacle may comprise a second keyed interface configured to be coupled with the first keyed interface, the electrical receptacle further comprising terminals disposed on sides of the electrical receptacle. Spring-biased terminals may be coupled to the face plate and coupled with the terminals. A powered feature may be coupled to the face plate and configured to be electrically coupled to the electrical receptacle through the spring-biased terminals when the first keyed interface and the second keyed interface are mateably coupled. Power may not be supplied from the electrical receptacle to the powered feature when the first keyed interface is not mateably coupled with the second keyed interface.
