A power supply arrangement and a method for operating a charging socket are also provided.

A tamper resistant nightlight for placement in an electrical receptacle, the nightlight includes a body that has a base with an LED circuit and plug blades extending from the body. A housing includes a locking element configured to restrict a child from removing the nightlight from the electrical receptacle through a flange that extends away from the body to be positioned behind a rear surface of an electrical wall plate associated with the electrical receptacle to prevent the tamper resistant nightlight from being removed from the electrical receptacle while the electrical wall plate is coupled to the electrical receptacle.

An arc prevention system including a jack having a receptacle, a modular connector sized to be positioned in the receptacle of the jack, the modular connector including a plurality of contacts, with at least two of the contacts creating an energized electrical path with an external power source in electrical communication with the external power source, a latch extending from a top surface of the modular connector, a switching unit positioned on the latch, a plug unit positioned between the latch and the jack that prevents the modular connector from moving out of the receptacle, a control circuit in electrical communication with switch and the at least two energized contacts, where the electrical path between the control circuit and the switching unit is energized when the plug engages the switching unit on the latch, and the control circuit adjusts the energized electrical path to a predetermined electrical level.

Disclosed herein is a leakage protector, which includes a housing. A base plate and a brush are arranged in the housing. A first conducting strip and a second conducting strip spaced apart are arranged on the base plate. The brush is provided with contact pins to contact the first conducting strip and the second conducting strip, respectively. The second conducting strip can generate different analog voltages, and the first conducting strip is configured to transmit different analog voltages to a microprocessor. A user can drive the brush to move through an actuating part, and set the power-on time of the leakage protector in one step.

A data line and a charging device are provided. The data line includes a Type-A interface, a first interface, a wire, and a circuit identification module. The Type-A interface is correspondingly connected to a VBUS pin, a D+ pin, a D− pin, and a GND pin in the first interface. The circuit identification module includes a pull-up resistor, a switch circuit, a filter circuit, and a comparator circuit. The comparator circuit controls the first end and the second end or the third end of the switch circuit to be connected.

An adapter, including a socket body, a guiding body, a movable conducting strip and a control member. The guiding body and the movable conducting strip are both disposed on one side of the socket body facing away from jacks, the control member is connected to the movable conducting strip in a transmission fashion, and is configured to drive the movable conducting strip to rotate relative to the socket body.

An automobile connection cable is configured with a controller area network (CAN-bus) circuit design and provided with a protocol interface between the J533 connector and USB Type-C. The function of switching between different protocols is achieved through the configuration of the cable assembly, so that the driver-assistance system ensures a better adaptability to the VAG vehicle models of Volkswagen Corporation (VAG). When the vehicle is shut off, the circuit control board can also control the constant power supply system between the external device and the vehicle, thereby reducing power consumption.
