摘要： An electrical connector includes a locking plug, a lock actuator, a strain relief, and an exterior mating surface. The locking plug includes a locking mechanism and the lock actuator is coupled to the locking mechanism. The strain relief is coupled to the locking plug and the exterior mating surface is coupled to the locking plug and axially moveable relative to the locking plug to move the lock actuator.

摘要： Anti-arcing circuits are described herein that are configured to prevent or substantially mitigate arcing when a power adapter is connected/disconnected from a client device. The anti-arcing circuit restricts power supplied when a connection of a connector of a power adapter to the adapter interface is not fully established. The anti-arcing circuit is further configured to detect when a connection is made and remove the restriction to supply power for operations of the client device. In one approach, the anti-arcing circuit includes two different paths and components associated with a detection mode and operational mode respectively. In the detection mode, power supply is suppressed and a current pulse may be sent to determine if a connection is established. If current is detected, a switch is made to operational mode and power for normal device operations is supplied.

摘要： A leakage reduction circuit is described herein that is configured to reduce high voltage leakage that may occur in electrical power step-down scenarios. The leakage reduction circuit, for instance, may be employed in a power adapter for a client device, such as a mobile computing device. For example, a power adapter may include a high voltage alternating current (AC) input, and circuitry for converting the AC input into lower voltage direct current (DC) for output to a client device. Implementations of the disclosed leakage reduction circuit include an arrangement of capacitors that provides a noise return path (e.g., for common mode noise) in a power adapter, while reducing high voltage leakage that may occur from a high voltage AC input to a lower voltage DC output of the power adapter.

摘要： A power supply unit having improved resistance to overheating caused by electrically conductive environmental contamination of electrical contacts of a connector of the power supply unit is disclosed. In one example, the connector includes one or more electrical contacts configured to receive one or more signals that indicate the connector is connected to an electronic device. The power supply unit includes a protection circuit that is configured to electrically disconnect the power supply unit from the connector based on detecting that a voltage on at least one of the one or more electrical contacts is greater than an expected/reference voltage. The higher than expected voltage may indicate that electrically conductive contamination has created a short between different electrical contacts of the connector. The power supply unit may be disabled based on detection of the electrically conductive contamination in order to prevent overheating and/or degradation of the connector.
