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. Kwan, Kevin A. Oberther

Patent number: 9142908Abstract: Various embodiments of low profile male connectors are described. In one embodiment, a connector includes a plug housing having a depth and an interior cavity designed to accommodate pins that extend within the interior cavity in a direction of the depth. The plug housing may be designed to be fully insertable into a receptacle connector of an electronic device, and to have a rear surface that conforms with a shape of an exterior surface of the electronic device. The pins arranged in the plug housing may include various features, such as connecting portions protruding from the plug housing at an angle of approximately 90 degrees for coupling to a cable, bases including cutouts for extending a length of an elongated shaft of the pin, barbs for engaging the plug housing, and limit stops for distributing a force applied to the elongated shaft upon engagement with a receiving pin.Type: GrantFiled: May 19, 2014Date of Patent: September 22, 2015Assignee: Apple Inc.Inventors: Cesar Lozano Villarreal, Dominic E. Dolci, Victoria A. Spielmann, Ricardo A. Mariano, Alexander M. Kwan, James G. Smeenge, Daniele De luliis

Patent number: 8782869Abstract: A connector of a cable (e.g., a 30-pin connector) can be used to facilitate various security-related and other functionalities. For example, a connector can include security locking mechanisms for engaging or locking the connector to a portable electronic device. A connector can additionally support the transmission of security signals, data signals, power, and/or the like. An unlocking tool can be used to disengage a connector locked to the portable electronic device. More specifically, the unlocking tool can be applied to a connector and cause the locking mechanisms of the connector to release such that the connector can be freely disconnected from a connected portable electronic device.Type: GrantFiled: May 17, 2011Date of Patent: July 22, 2014Assignee: Apple Inc.Inventors: Dominic E.

Patent number: 8659889Abstract: Various embodiments of digital signage systems and docking stations are described. In one embodiment, a digital signage system includes an electronic device having a rear surface and an opposing front surface at which a display of the electronic device may be viewed. The system also includes a body for supporting the electronic device. A recessed region is formed in the body from a top surface of the body, and the electronic device is positioned within the recessed region such that the rear surface of the electronic device fits entirely within the recessed region and the front surface of the electronic device is substantially flush with a portion of a top surface of the body that surrounds the recessed region. An aperture may be formed at least partially through the recessed region for receiving a cable assembly operable to connect to the electronic device.Type: GrantFiled: May 20, 2011Date of Patent: February 25, 2014Assignee: Apple Inc.Inventors: Dominic E.
