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.

Devices and systems having a plug and socket connection for resisting or preventing liquid, moisture, vapor, and the like, from contacting the internal electrical circuitry, is provided. Such an electrical device includes a power source socket coupled to a connector and a cap seal coupled to the connector. The power source socket further includes power source wires and the connector includes power distribution wires. The connections between the power source socket and the connector, between each pair of connectors, and between the connector and the cap seal are sealed to exclude moisture/liquid from causing shorting, as is described in more detail below.

The present disclosure provides an adapter assembly. Portion of the main body of the plug adapter is penetrated through the opening and exposed to the exterior of the accommodation space. Each protrusion is penetrated through the concave and exposed to the exterior of the accommodation space. Each protrusion exposed to the exterior of the accommodation space is connected with the position-limiting portion through the rotation of the plug adapter. Each fastening element is plugged into the first hole and the second hole. The plug adapter is fastened to the casing through the fastening element and the connection between the protrusion and the position-limiting portion. The adapter assembly includes two impact bearing points. One is formed by the fastening element, and the other is formed by the connection between the protrusion and the position-limiting portion. The stability and the waterproof capability of the adapter assembly are enhanced.

An electrical connector includes: a plastic seat; a tongue; and two rows of terminals; characterized in that a front section of the tongue is a thinner plate body, top and bottom surfaces of the thinner plate body are two front-section surfaces, a rear section of the tongue is a thicker plate body, top and bottom surfaces of the thicker plate body are two rear-section surfaces, the rear-section surface of one of the top and bottom surfaces of the tongue projects more than the entire front-section surface of the corresponding one of the top and bottom surfaces of the tongue by a height so that a step is formed between the rear-section and front-section surfaces of each of the top and bottom surfaces of the tongue. A combination of the bidirectional duplex electrical connector and a docking electrical connector is also provided.

A power connection assembly for an appliance includes a receptacle that has an inner wall. The inner wall defines a cavity. A channel is defined by the inner wall and is in communication with the cavity. A power cord is configured to be at least partially received by the cavity of the receptacle. A cap is rotatable between a locked position and an unlocked position and is configured to at least partially encase the power cord. A protrusion extends radially from the cap. A switch is positioned proximate the channel and is operable between an open position and a closed position. The protrusion is received by the channel and is configured to move the switch to the closed position.

A mounting assembly for mechanical and electrical engagement of a power module includes a stem having a base operably coupled to the power module and a distal end distal the base, a first electrode arm extending perpendicularly from a first side of the and having formed thereon a first electrode disposed on the first electrode arm to form a first incline surface, and a first locking arm extending perpendicularly from the first side of the and having formed thereon a first locking surface. A plane of the first incline surface intersects a plane of the first locking surface.
