  • Patent number: 8967887
    Abstract: Disclosed is a high speed flex circuit electronic interface in combination with a sealed optical connectorization approach for optical coupling. In a preferred embodiment, at a front end of the connector a wedge seal ring or “press ring” is pressed into the end of a slide tube, both of which are, in a preferred embodiment, made of metal such as stainless steel. The wedge end shape of the press ring in this preferred embodiment allows it to be easily pushed into the inside diameter of the slide tube, expanding the slide tube to create a radial surface seal maintained by the hoop stress developed in the slide tube initiated by the press ring, thereby creating a hermetic seal on a cylindrical portion of the flange assembly connector. A flex-circuit sealed back-end of the connector uses, in a preferred embodiment, polymer to polymer or polymer to metal bonding to create a hermetic seal on the back end.
