Description

BACKGROUND OF THE INVENTION

The present invention is directed to a patch panel and strain relief bar assembly and, more particularly, to quick release brackets for removably securing a strain relief bar to a patch panel.

U.S. Pat. No. 6,818,834 discloses two mounting elements used to secure a strain relief bar to the rear side of a patch panel with threaded screws. Moreover, U.S. Pat. No. 6,568,542 discloses two anchor elements used to secure a strain relief bar to the rear side of a patch panel. However, neither of these prior art patents disclose quick release brackets for removably securing a strain relief bar assembly to a patch panel.

SUMMARY OF THE INVENTION

It would be desirable to provide quick release brackets that allow a strain relief bar to be removed from a patch panel for easy moves, adds and changes.

It would also be desirable to provide quick release brackets that allow a strain relief bar to be removed from a patch panel without using tools.

A patch panel and strain relief bar assembly includes a patch panel, two bracket assemblies connected to the patch panel and a strain relief bar connected to the bracket assemblies. Each bracket assembly includes a first bracket and a second bracket removably secured to the first bracket. The first bracket is connected to the patch panel, and the first bracket has a tab including a cantilever that secures the first bracket to the second bracket. The first bracket also includes two rollover edges connected to the tab. The second bracket is connected to the strain relief bar, and the second bracket has a tab including an aperture that receives a portion of the first bracket therein.

Preferably, the first bracket is mounted between the patch panel and the rack.

Preferably, the strain relief bar supports cable exiting from a rear side of the patch panel, and a cable tie secures the cable to the strain relief bar.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

FIGS. 1-13 illustrate a patch panel and strain relief bar assembly 20 for use on either a rack cabinet or an open-frame rack, such as rack 22. As best seen in FIG. 1, rack 22 has equidistantly-spaced mounting holes 24 positioned vertically therealong. As shown in FIG. 3, assembly 20 includes patch panel 26, quick release brackets 28, 30 which attach to rack 22, and strain relief bar 32.

Patch panel 26 includes a frame 34 having mounting holes 36 at each end for securing patch panel 26 to the front side of rack 22 using screws 38. Frame 34 also includes connectors 40 having cable 42 exiting from the rear side thereof, as shown in FIG. 2. As best seen in FIG. 1, frame mounting holes 36 align with rack mounting holes 24, and screws 38 are used to secure patch panel 26 to rack 22.

Bracket 28 and bracket 30 are universal. That is, bracket 28 can be flipped over and used as bracket 30 on the other side of rack 22, and vice versa. Accordingly, bracket 28 will be described below, with the understanding that bracket 30 is identical and functions identically.

As best seen in FIG. 4, bracket 28 includes a latching bracket 44 and a tab bracket 46. Latching bracket 44 has mounting holes 48 which align with frame mounting holes 36 and rack mounting holes 24, and latching bracket 44 is secured to the front side of rack 22 using screws 38. Latching bracket 44 is attached between patch panel 26 and rack 22, sandwiching all the parts together as shown in FIGS. 9-11. Latching bracket 44 also has a tab 50 including a cantilever 52 and two rollover edges 54, 56 for securing latching bracket 44 to tab bracket 46.

Tab bracket 46 has mounting holes 58 that align with strain relief bar mounting holes 60 to secure tab bracket 46 to strain relief bar 32, as shown in FIG. 5. Tab bracket 46 also has a tab 62 including an aperture 64 for receiving cantilever 52 therein, as best seen in FIGS. 11 and 12. Tab 62 allows strain relief bar 32 to be secured to latching bracket 44 and then removed, if needed. Strain relief bar 32 supports cable 42 exiting from the back side of patch panel 26 to assist in cable management. Moreover, as best seen in FIG. 13, a fastener, such as cable tie 66, may be used to secure cable 42 to strain relief bar 32.

In operation, latching bracket mounting holes 48 are aligned with frame mounting holes 36, and screws 38 secure patch panel 26 and latching bracket 44 to the front side of rack 22. Next, strain relief bar 32 is secured to tab bracket 46 using screws 68 to form strain relief bar assembly 70. As shown in FIG. 5, screw 68 secures strain relief bar 32 to tab bracket 46 in the middle mounting hole 58 on tab bracket 46. However, it is likewise contemplated that strain relief bar 32 may be secured to tab bracket 46 at either of the other two holes 58 shown therein.

As shown in FIGS. 5 and 6, strain relief bar assembly 70 is moved upward and positioned in alignment with latching bracket 44 (see FIGS. 7-9). As shown in FIGS. 10 and 11, strain relief bar assembly 70 is pushed into latching bracket 44, locking tab bracket 46 therein. Cantilever 52 will deflect approximately 0.03 inches when tab bracket 46 is inserted into latching bracket 44. This deflection allows for some movement or adjustment that may be needed at the front side of patch panel 26. As best seen in FIG. 11, cantilever 52 is secured within aperture 64. Moreover, rolled over edges 54, 56 entrap strain relief bar assembly 70, preventing tab bracket 46 from moving up or down when it is in a locked position. Strain relief bar assembly 70 can be removed from latching bracket 44, if necessary, using approximately 15 pounds of force.

The disclosed invention provides two quick relief brackets for removably securing a strain relief bar to a patch panel. It should be noted that the above-described illustrated embodiments and preferred embodiments of the invention are not an exhaustive listing of the form such a patch panel and strain relief bar assembly in accordance with the invention might take; rather, it serves as exemplary and illustrative of embodiments of the invention as presently understood. Many other forms of the invention are believed to exist.
