Power adapters having a small-form factor, can deliver a large amount of power, can charge multiple electronic devices, and can allocate power between the multiple electronic devices in an efficient manner. One example can provide power adapters having small form factor that can be achieved by including space-efficient structures. This example can have an enclosure with first openings for power prongs, a second opening for a first connector receptacle, and a third opening for a second connector receptacle. An alignment adapter can be electromagnetically located between the power prongs and the first connector receptacle and between the power prongs and the second connector receptacle. The alignment adapter can include a compensating feature to allow each of the power prongs to be aligned with corresponding first openings, the first connector receptacle to be aligned with the second opening, and the second connector receptacle to be aligned with the third opening.

Space-efficient structures for multi-port power adapters

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.

Power adapter for electronic devices

An enclosure for an electronic device includes a housing having a wall defining a cavity that is configured to receive an electronic assembly therein. The wall includes a distal end having a tongue. A cap is sized to attach to the housing with a corresponding groove that is formed in a perimeter of the cap. A double shear weld joint is formed between the tongue and the groove such that flash from the weld is contained within the enclosure and is not visible on the exterior surface of the enclosure.
