  • Patent number: 6435898
    Abstract: A snap-in jack assembly for a multi-conductor communications jack allow a plurality of insulated conductors forced into associated insulation displacing contacts having conductor-cutting anvils to establish a mechanical and electrical joint with an insulated metallic conductor. The force performed by an impact tool having a cutting edge for severing a portion of the insulated conductor which extends beyond the jack lead frame. A series of anvils adjacent to the frame and to the insulation displacing contacts support the insulated conductor and insure a clean cut without injury to the conductor or insulation.
    Type: Grant
    Filed: September 15, 1998
    Date of Patent: August 20, 2002
    Assignee: Leviton Manufacturing Co., Inc.
    Inventors: Douglas Sahlberg, DeWayne Anderson
  • Publication number: 20010012719
    Abstract: A multi-conductor communications jack where the individual insulated conductors are forced into associated insulation displacing contacts to make a mechanical and electrical joint with the metallic conductor therein by means of an impact tool which also has thereon a cutting edge for severing the portion of the insulated conductor that extends beyond the jack lead frame. The improvement comprising a series of anvils adjacent the frame and insulation displacing contacts to support the insulated conductor and insure a clean cut without injury to the conductor or insulation.

  • Patent number: 5645444
    Abstract: A multi-conductor communications jack where the individual insulated conductors are forced into associated insulation displacing contacts to make a mechanical and electrical joint with the metallic conductor therein by means of an impact tool which also has thereon a cutting edge for severing the portion of the insulated conductor that extends beyond the jack lead frame. The improvement comprising a series of anvils adjacent the frame and insulation displacing contacts to support the insulated conductor and insure a clean cut without injury to the conductor or insulation and without having to employ two separate tools in two separate operations. The first tool to force the conductor into the contact slot and the second tool, in a separate operation, to sever the excess conductor.
