  • Patent number: 7544893
    Abstract: The present invention provides a wiring duct assembly including a duct base, a cover, and an end cap. The end cap is attached to the open end of the duct base with a friction fit to prevent any objects from accidentally entering the inside of the wiring duct. The cover attaches to the duct base forming an enclosure for holding the wiring therein. The end cap is designed to fit on the inside of the duct base so that the end cap does not interfere and add to the overall size of the wiring duct.

  • Publication number: 20080016655
    Abstract: An authentically verifiable cable tie made from a formulation that includes a plastic resin in an amount of from about 90% to 99% by weight and an additive in an amount of from about 1% to 10% by weight that is viewable by the unassisted eye when exposed to an infrared light source. The plastic resin is preferably nylon, more preferably nylon 6,6, and the additive is a nylon modified concentrate. The cable tie can have a locking mechanism and, preferably, once the locking mechanism is engaged, it cannot be opened without damaging it.

  • Patent number: 5548489
    Abstract: A wiring patch panel cabinet accommodates plural termination devices. A cabinet support structure includes spaced apart top and bottom walls and opposed sidewalls. The cabinet support structure secures a plurality of individual patch panels. Each patch panel accommodates termination devices of a given type. The termination devices of one patch panel may be different from the termination devices of another patch panel supported by the cabinet structure. The patch panels are supported by the cabinet in side-by-side vertical orientation to facilitate removal and repair of an individual patch panel without disturbing adjacent patch panels.

  • Patent number: 5531611
    Abstract: A connector module for use in a local area network having a plurality of workstations in connection with a hub, wherein each workstation is hard wired to a printed circuit board mounted in the module. The module further includes a wiring assembly connected to the board and a cable leading from the hub. The face of the panel includes a plurality of jacks mounted therein, which are also electrically connected to the printed circuit board. Initially, workstations are electrically connected to the hub through the wiring assembly, which is preferably a twisted pair flat cable. Alternately, the wiring assembly may be disconnected from the board, and an upgraded hub interconnected with the workstations through the jacks in the face of the module with minimal re-wiring required.

  • Patent number: 5167530
    Abstract: A patch panel assembly includes a patch panel to which plural elongate jack clusters are mounted. The jack clusters are supported by the panel within openings therein. Each jack cluster has a front face adjacent a front surface of the panel and an opposed rear face adjacent a rear surface of the panel. Each jack cluster includes openings therein for receipt of plug type connectors from the front face thereof. In addition, each jack cluster includes a pair of mounting elements extending from the rear face thereof at opposed ends thereof. The pair of mounting elements are mutually transversely offset with respect to one another. The mounting elements support an elongate mass termination connector at an angularly offset relation with respect to the jack cluster.
