Publication number: 20240405472Abstract: Power adapters and other electronic devices that are durable and can provide a large amount of power while having a small form factor. An example can provide a durable power adapter by providing a connector receptacle having a reinforced tongue. The tongue of the connector receptacle can be reinforced by having a center plate with one or more vertical portions that can be at least approximately at a right angle to a lateral portion of the center plate. This and other examples can provide a large amount of power while having a small form factor by providing a space efficient transformer having thermal dissipation components. This and other examples can provide a small form-factor by including a series of chokes formed as a module and including a variety of types of wires.Type: ApplicationFiled: January 16, 2024Publication date: December 5, 2024Applicant: Apple Inc.Inventors: Bahram Raad, Cesar Lozano Villarreal, Mathieu P.

Patent number: 11515679Abstract: 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.Type: GrantFiled: November 6, 2020Date of Patent: November 29, 2022Assignee: Apple Inc.Inventors: Matthew A. Lashinsky, Arun R. Varma, Cesar Lozano Villarreal, Mathieu P. Roy, Balal Khan, Johnathan D. Simeroth

Patent number: 11516929Abstract: 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.Type: GrantFiled: August 18, 2020Date of Patent: November 29, 2022Assignee: APPLE INC.Inventors: Peter A. Dvorak, Jeremy M. Dahl, Michael A. Foote, Brian K. Thorne, Cesar Lozano Villarreal

Patent number: 9694526Abstract: 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.Type: GrantFiled: September 26, 2013Date of Patent: July 4, 2017Assignee: Apple Inc.Inventors: Cesar Lozano Villarreal, Richard J.

Publication number: 20170054257Abstract: 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.Type: ApplicationFiled: August 31, 2016Publication date: February 23, 2017Applicant: APPLE INC.Inventors: Cesar Lozano Villarreal, Ruenjou Lu, Mahmoud R.

Patent number: 9486956Abstract: 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.Type: GrantFiled: May 1, 2014Date of Patent: November 8, 2016Assignee: Apple Inc.Inventors: Cesar Lozano Villarreal, Alexander M.

Patent number: 9331441Abstract: 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.Type: GrantFiled: September 11, 2014Date of Patent: May 3, 2016Assignee: APPLE INC.Inventors: Mathieu P.
