Publication number: 20180013231Abstract: Magnetic connectors that may be readily manufactured and provide a high landed force and labels for magnetic connectors that may protect magnets or magnetic elements in the connectors, provide an aesthetically pleasing appearance, and improve the magnetic performance of the connectors. In various examples, power and signal paths may be formed using contacts that are separate from magnets or magnetic elements, paths may be formed using magnets or magnetic elements, or paths may be formed using a combination of contacts and magnets and magnetic elements. The magnets may have various arrangements. One or more magnets may be used in conjunction with magnetic elements. The interface surface of these magnets and magnetic elements may have various contours, such as flat, spline, or involute.Type: ApplicationFiled: July 18, 2017Publication date: January 11, 2018Applicant: Apple Inc.Inventors: John C.

Publication number: 20170317445Abstract: An electrical plug and receptacle relying on magnetic force from an electromagnet to maintain contact are disclosed. The plug and receptacle can be used as part of a power adapter for connecting an electronic device, such as a laptop computer, to a power supply. The plug includes electrical contacts, which are preferably biased toward corresponding contacts on the receptacle. The plug and receptacle each have a magnetic element. The magnetic element on one of the plug or receptacle can be a magnet or ferromagnetic material. The magnetic element on the other of the plug or receptacle is an electromagnet. When the plug and receptacle are brought into proximity, the magnetic attraction between the electromagnet magnet and its complement, whether another magnet or a ferromagnetic material, maintains the contacts in an electrically conductive relationship.Type: ApplicationFiled: July 16, 2017Publication date: November 2, 2017Applicant: APPLE INC.Inventors: Matthew Dean Rohrbach, Mark Edward Doutt, Bartley K.

Patent number: 9791634Abstract: Circuits, apparatus, and methods that provide a connector system that can supply both power and data to a mobile computing or other type of device using a single connection. Further examples also provide a power and data adapter that can provide power and data to a mobile computing device using a single cable. Further examples provide an easy disengagement when a cable connected to the connector is pulled. One such example provides a magnetic connector that uncouples without binding when its cord is pulled. Another example prevents power from being provided at a connector insert until the connector insert is placed in a connector receptacle.Type: GrantFiled: July 8, 2014Date of Patent: October 17, 2017Assignee: Apple Inc.Inventor: John C.
