  • Publication number: 20200059021
    Abstract: In one embodiment, an eye of needle (EON) press-fit pin includes a base, a tip, and a compliant portion extending longitudinally between the base and the tip and comprising a pair of resilient deformable arms joined at opposite ends and defining an opening therebetween. The arms each include an outer surface for at least partial engagement with walls of an electrical via upon insertion therein. The outer surface of each of the arms includes a central segment having a flat longitudinal surface and converges from the central segment towards the base and the tip. The arms each further include an inner surface defining the opening and forming an elongated portion at each end of the opening for stress relief.

  • Patent number: 10522280
    Abstract: The subject disclosure relates to improved integrated connector module (ICM) designs for Ethernet applications. Some aspects provide an improved integrated connector module transformer (ICMt), including a wafer configured to hold a plurality of toroid elements, wherein the wafer is comprised of two or more mechanically coupled wafer portions. The ICMt can include one or more Electro Magnetic Interference (EMI) fingers that are configured to contact a ground pad of a printed circuit board (PCB) in order to provide a low-inductance connection between the ICMt and the ground pad of the PCB.
