## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of U.S. provisional patent application 61/165,969 filed Apr. 2, 2009, the entire contents of which are incorporated herein by reference.


BACKGROUND
Telecommunications patch panels are used to provide a location for a number of ports or outlets to interface with cabling for interconnecting with a variety of devices and equipment. When wires are connected to an outlet, this is referred to in the art as outlet termination. Current patch panel outlet termination falls into two broad categories; (1) terminate in panel (typically punch down), and (2) terminate-out-of-panel (may be punch down or “toolless”) and then fix as individuals or groups to the patch panel. For terminate-out-of-panel type panels, the termination may be performed where the installer can easily see, manipulate, and inspect the terminations (a significant advantage). The art would be benefited by improvements in the ease, speed and reliability of terminating and installing outlets into a patch panel.
Further, each outlet or port in a patch panel is typically labeled with a port identifier. These port identifiers may come in a variety of forms. The art would be benefited by improvements in the clarity and flexibility of port identifiers.

The dual row, multiport bezel 114 includes nubs 30 that engage openings in the 48 port, 1U patch panel 100. The dual row, multiport bezel 114 also includes a guide 38 as described above. As there are two rows of outlet openings, there are two notches 36 for receiving conductive strips 34. FIG. 9 is a rear, perspective view of a dual row, multiport bezel 114. The dual row, multiport bezel 114 includes latches 42 for securing outlets in cavities 116 as described above.
FIG. 10 is a perspective view of an outlet being mounted in a cavity of a single row, multiport bezel. An outlet 300 is inserted into cavity 16 along a linear axis. Outlet 300 may be similar to the outlet described in U.S. patent application Ser. No. 12/058,004, the entire contents of which are incorporated herein by reference. When the outlet 300 initially enters cavity 16, latch 42 is deflected downward by the housing of outlet 300. Once the housing clears latch 42, latch 42 flexes upwards and returns to its rest position to secure outlet 300 to the single row, multiport bezel 14. This state is shown in FIG. 11.
FIG. 11 is a perspective view of installation of a cable manager 400. The cable tie down point 18 is defined by a rectangular or square opening having a T-shaped prong 19 positioned therein. The T-shaped prong extends along the axis of insertion of the outlet 300. In FIG. 11, the distal end of the T is pointing away from the single row, multiport bezel 14. In alternate embodiments, the distal end of the T is pointing towards the single row, multiport bezel 14. The cable manager 400 (e.g., a cable tie-down) may be looped around cable 402, inserted into the opening in cable tie down point 18, and slid over T-shaped prong 19. The cable manager 400 is then tightened to secure the cable 402 to the cable tie down point 18.
FIGS. 12A and 12B depicts rear and rear, perspective views of a label holder 500. Label holder 500 is made from a clear material and includes a pocket 520 formed between front and rear faces of the label holder 500. Latches 510 extend from the rear face of the label holder 500. Latches 510 have an arcuate body 512 with protrusions 514 formed on an upper surface of the arcuate body 512. As noted above, the latches 510 are inserted in openings formed by the cutouts 70 formed above the outlet openings in the single row, multiport bezel 14 and dual row, multiport bezel 114.
In mounting the label holder 500 to a panel, latches 510 engage openings provided by cutouts 70. The arcuate body 512 deflects to a linear shape to enter the cutout 70 and then resumes its rest shape once projections 514 clear the edge of the patch panel. The edge of the patch panel rests in a recess defined by the projections 514 to secure the label holder 500 to the patch panel 10 or 100.
FIGS. 13A and 13B depict label icons 522 or a label strip 524 being mounted in the label holder 500. The pocket 520 can receive a label strip 524 that extends from one end of the label holder 500 to the other. The label strip may be written on or otherwise imprinted on to identify ports on the patch panel. The icons are discrete elements that may be made from paper, card stock, plastic, etc. The icons may also include indicia identifying the port or representing the nature of the port (e.g., voice or data). The pocket 520 includes internal ribs that keep the icons 522 in position laterally once placed in the label holder 500.
FIG. 14 illustrates installation of a single row, multiport bezel in a panel frame of a 24 port, 1U patch panel 10. The installation requires no tools and facilitates assembly of the patch panel 10. The single row, multiport bezel 14 is inserted in the panel frame 12 with the upper, front edge leading the single row, multiport bezel 14. The single row, multiport bezel 14 is rotated so that nubs 30 engage openings 32 in the patch panel frame 12. Guide 38 enters slot 50 (FIG. 15) to maintain travel of the single row, multiport bezel 14 on a linear path.
FIG. 15 is a perspective view of a patch panel frame 12 showing details of tray 15. Openings 52 receive latches 53 on the single row, multiport bezel 14. Tension members 54 are formed in the base of patch panel frame 12 by bending a tab upwards from the base. When the single row, multiport bezel 14 is mounted to the patch panel frame 12, the tension member applies a spring force to the bottom of the single row, multiport bezel 14. This force positions the single row, multiport bezel 14 relative to the patch panel frame 12 and produces a secure fit in the patch panel frame 12.
FIG. 16 illustrates an outlet 300 mounted in a cavity of single row, multiport bezel installed in a panel frame of a 24 port, 1U patch panel. As shown in FIG. 16, the conductive strip 34 contacts the housing of the outlet 300. In embodiments where the outlet is a shielded outlet with a conductive housing, the outlet housing is connected to ground through the conductive strip 34, patch panel frame 12 and ground lugs at ground lug locations 20. It is understood that an unshielded outlet may be mounted in the single row, multiport bezel 14 with no adverse effects. It should be noted that the dual row, multiport bezel 114 is mounted to the patch panel frame 112 in the same manner and the description of FIGS. 14-15 pertains equally to the dual row, multiport bezel 114.
FIG. 17 is a perspective view of a 24 port, 1U patch panel modified for use with intelligent patch panel monitoring. In intelligent patch panel systems, a circuit board may be installed on the face of the patch panel in order to provide a connection point for monitoring connections. Such systems are described in pending U.S. patent application Ser. No. 12/247,472, the entire contents of which are incorporated herein by reference.
FIG. 18 is an exploded perspective view of a 24 port, 1U patch panel modified for use with intelligent patch panel monitoring. The patch panel frame 212 is similar to patch panel frame 12, with the exception the patch panel frame 212 includes cutouts 216 for receiving jacks 218 on the back of circuit board 700. Circuit board 700 includes contact points 702 for making electrical contact with monitoring contacts. A cover 800 is used to conceal the circuit board 700. The single row, multiport bezel 214 is similar to single row, multiport bezel 14 with the exception that single row, multiport bezel 214 includes cutouts 27 for accommodating jacks 218 on the circuit board 700.
FIG. 19 is a perspective view of two 48 port, 1U patch panels mounted in a rack. When two 48 port, 1U patch panels are mounted in this fashion, the spacing between outlets in both the horizontal and vertical directions is substantially similar, both within a panel and across panels. This improves performances by providing consistent inter-outlet effects (e.g., Alien near-end crosstalk) between panels.
Embodiments of the invention provide faster and easier installation of pre-terminated outlets, faster and easier cable management, high density with improved performance, port labeling with options for standard printer labels and or port id icons. Installation of outlets is superior to currently available products on the market in that the outlets are snapped into place with one linear motion instead of multiple actions required for securing. Cable management is superior in that standard zip-ties are used without the need for lacing through features and that the tie down features on the panel provide built in anti-snag features. Port ID is an improvement in flexibility of labeling in that it accepts standard size labels from market leading printers and custom port ID Icons.
Embodiments take the terminate-out-of-panel concept one step further in that it supports fast and easy fixing of the individual outlets to the panel. Outlets may also be removed without special tools (space permitting) and reinstalled multiple times into the same or other locations in the panel in a single linear motion. Outlets are held in place with a latch.
Proper cable management is an integral component in ensuring consistent high performance. Embodiments provide cable tie feature that allows the end user to first install the cable tie on the intended cable and then secure it to the panel manager without fishing the cable tie through holes. Additionally, the tie down feature has a built in anti-snag frame around it to keep the neighboring cables from being caught or damaged.
Port identification is typically required and the bare minimum is usually a port ID number. Embodiments allow the end user to enhance the port identification with a clear plastic label and icon holder. The label holder holds pre printed labels, standard labeler printed labels, and custom icons displaying phone, data, or other type symbols or text. The label holder is snapped into place with defeatable snap features. Port ID may be easily changed or revised without removing adhesives or other semi-permanent markings.
While the invention has been described with reference to exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt to a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed for carrying out this invention.
