  • Patent number: 11516929
    Abstract: A power adapter is disclosed. The power adapter includes housing parts that carries electronic components. To secure the housing parts together, one housing part includes snaps and another housing part includes protrusions and rails. During assembly, the protrusions slide under the snap, causing the snap to deflect in one direction, while the rails slide over the snap, which keeps the snap partially flat but also causes the snap to deflect in another direction. The engagement (during assembly) of the rails and the protrusions to opposing surfaces of the snap cause bi-directional deflection/bending of the snap. When each protrusion is positioned into an opening of the snap, the snap returns to a flat, non-deflected state, and the housing parts are secured together by the snap, protrusions, and rails. The rails support the snaps by limiting or preventing additional deflection of the snap, which subsequently promotes the housing remaining together.

  • Patent number: 11515679
    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.

  • Patent number: 9694526
    Abstract: Systems and methods of providing a tooling system for forming a unitary housing are disclosed herein. One embodiment may utilize a plurality of injection cavity slides. The slides may form the interior cavity of the housing. Utilizing a plurality of injection cavity slides to form a single cavity insert may allow the slides to be remove from an opening in the housing which is smaller than the cavity of the housing. Removing the slides from housing allows for the formation of housing having a unitary structure.

  • Publication number: 20170054257
    Abstract: Methods, systems, and apparatus for selectively communicating data and audio over a limited-size audio plug. A host device determines whether an audio accessory or a data communicating accessory is plugged therein via a signal, or lack thereof, communicated to the host device via the audio plug of the accessory. The host device then either communicates audio or data over the audio plug contacts that are typically used only for audio communication based on whether its connected to an audio accessory or data communicating accessory. An audio plug may also include a split-ring contact where multiple, independent contacts are formed in place of a single tip, ring, or sleeve contact. The split-ring contact may be used for communicating audio and/or data.

  • Patent number: 9486956
    Abstract: A dual-purpose transformer may be oriented in a plane perpendicular to planes in which printed circuit boards connected thereto are oriented, thereby providing structural support for a framework that can include a dense arrangement of internal power adapter components, in addition to stepping down voltage. Methods for ultrasonic welding are also provided and may be used to concurrently assemble, join and press-fit power adapter housing components. A ground lug is also provided that is shaped and located within a cover piece of a power adapter housing to allow for blind mating with a printed circuit board during an assembly process.

  • Patent number: 9333704
    Abstract: The described embodiments relate generally to ultrasonic welding and more particularly to performing an ultrasonic welding operation while rotating one part relative to a mating part. A non-uniform energy director can be disposed along a mating surface of a first part. The energy director can maintain a constant cross-sectional area while having a smaller height near a pivot point for the rotation and a larger height away from the pivot point. The varying height of the energy director can allow the tip of the energy director to come in contact with a second part rotating relative to the first part at approximately the same time during the ultrasonic welding process.

  • Patent number: 9331441
    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: This application includes multiple embodiments related to capacitors. In some embodiments, capacitors are set forth as having terminal leads that extend in parallel and opposing axial directions. The embodiments discussed herein relate to a capacitor module including one or more anodized pellets for providing a charge storage within the capacitor module. The capacitor module can be configured as a surface mounted or non-surface mounted capacitor module. The capacitor module can include an array of anodized pellets arranged in multiple rows or columns of anodized pellets connected by conductive trace included in the capacitor module. In a non-surface mounted embodiment of the capacitor module, the capacitor module can include cathode and anode connections that are exclusively on the side surfaces of the capacitor module.

  • Patent number: 9209547
    Abstract: Connector adapters that may allow contacts in a connector insert to form electrical connections with contacts in an incompatible connector receptacle. One example may provide a connector adapter for providing a connection between a connector insert and an incompatible connector receptacle. The connector adapter may be a magnetic connector providing a magnetic connector receptacle at a first end to accept a connector insert having an attraction plate. This connector adapter may further provide a connector insert having an attraction plate at a second end to insert into a magnetic connector receptacle on an electrical device.
