Patent number: 11432407Abstract: An electronic device package includes a molded case, a plurality of leads and a case lid. The molded case includes integrally formed side walls, end walls, and a bottom wall, which together define an interior for components. Each side wall includes top and bottom portions. The top portion includes first and second surfaces extending downward from a top edge of the side wall. The bottom portion has a top surface that extends away from the interior, a third surface extending downward from the top surface to a bottom edge, and a fourth surface extending downward from the second surface to the bottom wall. The leads are molded in the side wall from the bottom edge to the top edge. Each lead has an end extending above the top edge, and another end extending along the bottom edge of the side wall. The case lid is engaged with the molded case.Type: GrantFiled: October 16, 2018Date of Patent: August 30, 2022Assignee: XFMRS, Inc.Inventors: Tung Kong Luk, Yu Kun Liao

Publication number: 20210104849Abstract: A network jack includes a connector, an outer housing, and a circuit board. The connector receives a plug for conveying Ethernet network signals. The connector includes conductive leads disposed on opposite sides of a central bar. The connector has a connector housing formed in part by a plurality of walls defining an interior, wherein the central bar is disposed in the interior, and spaced part from each of plurality of walls. The outer housing is disposed about and contains the connector housing, and has a width approximately equal to a width of a housing of the plug. The circuit board is disposed within the housing, and supports a plurality of transformers and/or common-mode chokes. The circuit board provides at least a portion of an electrical connection between the conductive leads and the transformers and/or common mode chokes.Type: ApplicationFiled: October 28, 2019Publication date: April 8, 2021Inventors: Weijia Kong, Yukun Liao, Liang Huang, Gideon Lian, Tung Kong Luk, Buddy Woods, Drew Ciszar, Brenden Justus, Joe Huff, Anthony Imburgia
