  • Insulation displacement terminal for telecommunication devices
    Patent number: 5102347
    Abstract: An insulation displacement terminal comprises a clamp having an internally threaded tubular portion to accommodate a screw. An insulated telephone wire can be inserted into an aperture in the clamp. When the screw is screwed all the way into the clamp, a cylindrical blunt edge thereon will displace the insulation on the wire and make contact with the metal core of the wire. There is a sealing material in the terminal to seal around the point of contact. A well and axial hole in the screw can accommodate sealing material that is displaced by the screw.
