  • Patent number: 6629858
    Abstract: A shielded telecommunications connector comprising a conductive core having core side walls and a horizontal shield joined to and perpendicular to the side walls. At least one contact carrier contains a contact, the contact having an insulation displacement contact for making electrical connection with a wire, the contact carrier being positioned on the horizontal shield between the side walls. At least one termination cap receives the wire and the insulation displacement contact, the termination cap positioning the wire relative to the insulation displacement contact. Each of the sidewalls has a sidewall ledge and the termination cap includes two first lips positioned beneath the sidewall ledges. The horizontal shield extends beyond a length of the termination cap.

  • Patent number: 6505399
    Abstract: An improved cable preparation tool and an accompanying method which, when utilized concurrently, prepare fully shielded cables for termination into connecting devices. A preferred embodiment of the tool has hinged first and second tool handles biased together about a hinge by a resilient member. One end of a tool handle is fitted with a receptacle to receive and mount a detachable blade cartridge assembly which cuts the cable jacket and shielding metallic foils wrapped around individual pairs of insulated wires. A second receptacle is provided in either tool handle to receive a detachable template cartridge assembly which is used to properly position wires for termination into a connector. An exemplary method of cable preparation using the tool includes removing a cutting a cable jacket, cutting a plurality of foils and aligning wires using a single cable preparation tool.

  • Publication number: 20020115346
    Abstract: An embodiment is a telecommunication outlet mounted on a printed circuit board (PCB) including a vertical shield extension and an inner shield extension which protrude downwards beyond the PCB. The vertical shield extension and the inner shield extension form a cross structure protruding downwards beyond the PCB, in which the cross structure defines four shielded quadrants each for housing contact tails of a tip and ring pair protruding downwards beyond the PCB. Shielding contact tails from each other with the extensions of the cross structure provides enhanced shielding and reduces crosstalk.

  • Patent number: 6358091
    Abstract: A connector made up of a plug and outlet which, when mated, define four shielded quadrants, each of which houses a pair of contacts. Shield members within the plug overlap and shield members within the outlet overlap. In addition, shield members within the outlet overlap adjacent shield members in the plug when mated. Overlapping the shield members at each shield member junction provides enhanced shielding and reduced crosstalk.

  • Patent number: 6017229
    Abstract: An outlet door assembly that is retainable in both an open and a closed position is presented. In accordance with the present invention, the door comprises a pair of mounting arms having inwardly extending protrusions which are received in notches for retaining the door in the closed and open position. In one embodiment the connector housing has an outwardly extending protrusion within each of a pair of notches to define the positions for retaining the protrusions on the door arms. In another embodiment a door holder is employed which has pairs of notches, with one pair of notches receiving the protrusions of the door arms therein for retaining the door in a closed position and another pair of notches receiving the protrusions of the door arms therein for retaining the door in an open position. In both embodiments the door includes a channel for receiving an identification icon therein.

  • Patent number: 5795186
    Abstract: Multimedia bezels designed to receive a variety of connectors and fit within a standard panel cut-out. The bezels include top and bottom notches that engage the edge of the panel cut-out. An opening in the body of the bezel receives the connector. A resilient section allows one of the sets of notches to deflect towards the body for insertion in the panel cut-out. Once within the panel cut-out, the resilient section presses against the edge of the panel cut-out to firmly mount the bezel in the panel. The body of the bezel may be parallel (flat) or at an oblique angle (angled) to the panel. Both the flat and angled embodiments include icon holding grooves for receiving an icon for coding the port. In the flat embodiment, the icon also prevents deflection of the resilient section and acts as a lock. The bezels are side stackable so that a variety of simplex and duplex bezels can be utilized in a panel cut-out.

  • Patent number: 5791943
    Abstract: A modular outlet having reduced crosstalk is presented. The modular outlet of the present invention comprises a connector housing which supports a plurality of contacts and a termination cap mated to the housing for terminating a plurality of wires at one end of the contacts. The contacts are positioned on a contact carrier which is received in the housing. The contacts include current carrying plates which are stacked to induce capacitance between selected contacts. This method of achieving a controlled amount of capacitive coupling between selected contacts allows the modular outlet to meet or exceed Category 5 requirements. Further, while the modular outlet connections are positioned in accordance with a standard configuration, the insulation displacement contacts are sequentially positioned, thereby eliminating pair splitting when terminating.
