Abstract: Power adapters having a small-form factor, are capable of delivering a large amount of power, can charge multiple electronic devices, and can allocate power between the multiple electronic devices in an efficient manner.

Abstract: A power adapter for powering portable electronic devices is disclosed. The modifications and enhancements to the power adapter can reduce or eliminate the need for adhesives, flexible circuitry, and/or wiring. The power adapter includes multiple guide rails used to guide a circuit board (carrying components) to electrical springs. The electrical springs provide not only an electrical coupling, but also a mechanical coupling. As a result, wiring and/or adhesives is not required. Additionally, a cap is secured to the enclosure through melting part of the cap by, for example, ultrasonic welding without causing damage to the circuit board, as welding location(s) is/are in locations away from the electrical springs and other sensitive components. The power adapter further includes a connector connected to the circuit board. During assembly, the circuit board can pivot in three dimensions during assembly to align the connector with the cap.

Abstract: An enclosure for an electronic device includes a housing having wall defining a cavity that is configured to receive an electronic assembly therein. The wall includes a plurality of housing steps formed in an interior surface. A cap includes a side surface extending around a perimeter of the cap with a plurality of cap steps formed in the side surface. The cap is positioned at an entrance to the cavity such that the plurality of housing steps align with the plurality of cap steps and welded in place. Flash from the weld is captured in a flash trap so that no weld flash is visible on the exterior surface of the enclosure.

Abstract: An electrical power adapter has first and second prongs that are retractable and deployable. When the prongs are in the deployed position the adapter may be mated with a receptacle and when in the retracted position the adapter has a reduced physical size. A linkage couples the first prong to the second prongs such that the first and second prongs retract and deploy simultaneously. An actuation mechanism causes the prongs to have a first detent in the deployed position and a second detent in the retracted position.

Abstract: An electrical power adapter employs a magnetically coupled mechanism to retract and deploy prongs used to interface with an electrical receptacle. The magnetically coupled mechanism is linearly displaced by a user, converting the linear displacement to rotary motion, pivoting the retractable prongs between a deployed position and a retracted position. When the retractable prongs are in the deployed position the adapter may be mated with a receptacle and when in the retracted position the adapter has a reduced physical size.
