Patent number: 8727641Abstract: An optical connector includes a substrate, a photoelectric element and a positioning element on the substrate, a lens element, and an optical fiber. The positioning element defines a through hole, in which the photoelectric element is received to allow visual inspection for determining if the photoelectric element is positioned to a designated position in relation to the positioning element, and includes a positioning structure. The lens element includes an incident surface, an emitting surface, a reflecting surface, a locating structure and a first lens formed in the incident surface, and a second lens formed on the emitting surface and optically aligned with the first lens via the reflecting surface. The lens element is precisely positioned on the positioning element by matching the locating structure with the positioning structure, to align the first lens with the photo electric element. The optical fiber is aligned with the second lens.Type: GrantFiled: January 22, 2013Date of Patent: May 20, 2014Assignee: Hon Hai Precision Industry Co., Ltd.Inventor: Yi Hung

Publication number: 20140112627Abstract: Disclosed are lens blocks and methods for making the same. In one embodiment, the lens block includes at least one optical channel having an optical interface portion on a first side, and one or more magnetic materials attached to the lens block. In one embodiment, the lens block may include one or more opening for receiving the one or more magnetic materials. The one or more openings may be located on any suitable side of the lens block as desired. The magnetic materials provide attachment with a complimentary device having an optical interface. Consequently, the lens block allows for quick and easy assembly along with a robust structure for a large number of mating/unmating cycles. In other embodiments, the lens blocks disclosed may further include one or more electrical contacts for making a hybrid connection.Type: ApplicationFiled: December 7, 2013Publication date: April 24, 2014Applicant: Corning Cable Systems LLCInventors: Micah Colen Isenhour, Dennis Michael Knecht, James Phillip Luther

Patent number: 8702316Abstract: 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: October 22, 2010Date of Patent: April 22, 2014Assignee: Apple Inc.Inventors: John C. DiFonzo, Chris Ligtenberg, Michael Culbert

Patent number: 8702317Abstract: An optical connector having an optical fiber inserted into a connector main body includes a buckling regulating section whose length in an optical fiber insertion direction is formed variable and which regulates a buckling of the optical fiber while becoming short in an optical fiber insertion direction when the optical fiber is inserted into the connector main body. Even if an insertion area is made long, since no buckling of the optical fiber is generated, the buckling regulating section can sufficiently increase an insertion force of the optical fiber. Thus, even when foreign substances such as dusts enter and an insertion resistance increases, the optical fiber can be securely inserted. Further, the buckling regulating section is very advantageous to realize an end surface preparation of the optical fiber making use of the insertion force of the optical fiber such as a coating removing of the optical fiber, and an end surface grinding preparation of the optical fiber.Type: GrantFiled: August 6, 2010Date of Patent: April 22, 2014Assignee: Nippon Telegraph and Telephone CorporationInventors: Ryo Koyama, Kazuhide Nakajima, Masaaki Takaya, Toshio Kurashima, Masatoshi Shimizu, Kyoichi Nakamizo
