  • Patent number: 10404021
    Abstract: Connector receptacles and connector inserts that may be reliable, may readily manufactured, and may provide high signal quality for high speed signals with minimized signal noise, distortion losses, radiation, and interference. An example may provide a reliable connector receptacle by including a plurality of contacts, where each contact includes a first bend angling a contacting portion away from a tongue and a second bend angling a contacting portion towards the tongue, where the second bend is between the first bend and a front of the connector receptacle. Another example may provide a connector receptacle that may be readily manufactured by providing a tongue having tapered lead-ins for receiving contacting portions of contacts during assembly. Another example may provide a connector receptacle that provides isolation among signals by arranging through-hole portions of signal contacts in lines that are separated from each other by intervening through-hole portions of ground contacts.
