Abstract

A distribution module for use in a traditional electrical panel that provides coupling functionality for optical and electrical connectors. The distribution module is comprised of a housing with a passage defined therein. The distribution module further includes high density, modular coupling strips, which are chosen based on the type of connectors to be coupled. These coupling strips are joined together and then secured in the passage formed in the housing. Once assembled, the distribution module is received into an opening in the panel thereby integrating both optical and electrical couplers in a single panel.

Claims

1. A cable distribution module for interconnecting first and second transmission cables in a panel, the panel having at least one opening formed therethrough, said cable distribution module comprising:

a housing having a front, a back, a passage defined therethrough, and an exterior side wall extending between said front and said back, said housing being sized and shaped to be inserted in the opening of the panel, said passage being defined by upper and lower opposing walls;

a first coupling strip having a plurality of cable coupling ports arranged in a side-by-side configuration with each other, each of said cable coupling ports being adapted to engage the first transmission cable, said first coupling strip being configured to engage said housing within said passage;

a second coupling strip engaging said first coupling strip in a back-to-back configuration, said second coupling strip having an exterior which is symmetrical to the exterior of said first coupling strip and having a plurality of cable coupling ports arranged in a side-by-side configuration with each other such that each of said cable coupling ports of said second coupling strip complement one of said cable coupling ports of said first coupling strip, each of said cable coupling ports of said second coupling strip being adapted to engage the second transmission cable, said second coupling strip being configured to engage said housing within said passage,

said first and second coupling strips being configured to engage said housing within said passage in a first position and a second position such that, in said first position said cable coupling ports of said first coupling strip are arranged adjacent said front of said housing and said cable coupling ports of said second coupling strip are arranged adjacent said back of said housing, and in said second position said cable coupling ports of said second coupling strip are arranged adjacent said front of said housing and said cable coupling ports of said first coupling strip are arranged adjacent said back of said housing.

2. The distribution module of claim 1, wherein said housing has a pair of opposing pins, each of said pins extending outwardly from said exterior side wall of said housing, said pins being configured to pivotably engage the panel such that said housing is pivotable relative to the panel.

3. The distribution module of claim 1, wherein each of said upper and lower walls of said passage has a lip extending therefrom and into said passage, and wherein said first and second coupling strips each has flanges extending outwardly therefrom, each of said flanges being configured to engage one of said lips such that engagement of said flanges with said lips secures said first and second coupling strips to said housing within said passage.

4. The distribution module of claim 1, further comprising:

a cable slack tray extending outwardly from said back of said housing, said cable slack tray having a base and a spillway region arranged between said base and said housing, said base having an upper surface and a substantially cylindrical drum extending from said upper surface, said drum configured for spooling cable thereon, said spillway region configured as a trough extending below said base and said housing for facilitating engagement of the second cable with one of said cable coupling ports arranged adjacent said back of said housing.

5. The distribution module of claim 4, wherein said cable slack tray is removably mountable to said housing, said cable slack tray having a bifurcated mounting tab extending therefrom, said bifurcated mounting tab having a latch arm, and wherein said housing has a slot with an internal lip formed therein at said back of said housing, said internal slot being configured to receive said bifurcated mounting tab such that insertion of said bifurcated mounting tab within said slot allows said latch arm to engage said internal lip such that engagement of said latch arm with said internal lip secures said cable slack tray to said housing.

6. The distribution module of claim 4, wherein said drum has an upper edge and a wing attached thereto, said wing extending outwardly from said drum and forming a barrier for retaining cable on said drum.

7. The distribution module of claim 4, wherein said cable slack tray has strain relief means for securing a cable to said cable slack tray.

8. The distribution module of claim 7, wherein said strain relief means is an aperture in said cable slack tray through which the cable can be tied with a cable tie.

9. The distribution module of claim 1, wherein said housing has

a labeling region on said front for identifying said cable coupling ports;

and

an icon region on said front for identifying said cable coupling ports.

10. The distribution module of claim 1, further comprising:

a plurality of ferrule alignment sleeves, wherein each said sleeve is entrapped between one of said cable coupling ports in said first coupling strip and a complementary said coupling port in said second coupling strip.

11. The distribution module of claim 1, wherein said first coupling strip is a base coupling strip and said second coupling strip is a cap coupling strip.

12. The distribution module of claim 1, wherein each of said cable coupling ports of said first coupling strip is configured as one of the group consisting of ST, SC, LC and FC optical couplers, and each of said cable coupling ports of said second coupling strip is configured as one of the group consisting of ST, SC, LC and FC optical couplers.

13. The distribution module of claim 1, wherein said cable coupling ports of said first and second coupling strips are configured as coaxial electrical couplers.

14. A cable panel for interconnecting first and second transmission cables, said cable panel comprising:

a panel having a panel front, a panel back, and an opening formed therethrough, and;

a cable distribution module engaging said panel and movable between a mounted position and a retained position, in said mounted position said cable distribution module being securely mounted within said opening of said panel, in said retained position said cable distribution module being retained in a spaced orientation with said front of said panel, said cable distribution module having a housing, a first coupling strip and a second coupling strip;

said housing having a housing front, a housing back, a passage defined therethrough, and an exterior side wall extending between said housing front and said housing back, said housing being sized and shaped to be inserted in said opening of said panel, said passage being defined by upper and lower opposing walls;

said first coupling strip being configured to engage said housing within said passage, said first coupling strip having a plurality of cable coupling ports arranged in a side-by-side configuration with each other, each of said cable coupling ports being adapted to engage the first transmission cable;

a second coupling strip engaging said first coupling strip in a back-to-back configuration and being configured to engage said housing within said passage, said second coupling strip being symmetrical to said first coupling strip and having a plurality of cable coupling ports arranged in a side-by-side configuration with each other such that each of said cable coupling ports of said second coupling strip complement one of said cable coupling ports of said first coupling strip, each of said cable coupling ports of said second coupling strip being adapted to engage the second transmission cable;
