  • Contact terminal for modular plug
    Patent number: 5284447
    Abstract: A new and improved contact terminal for modular, telephone-style plugs. An elongated opening is provided in the central portion of the contact terminal for reducing capacitive coupling between contacts, resulting in better cross-talk isolation. Two parallel signal paths are also provided thereby, reducing signal reflections and improving the VSWR. A substantial savings in gold-plating is also provided by reducing the surface area of the contact terminal.
