Abstract

A multi-port or multi-outlet cassette that may be configured as a low profile, high-density cassette. Selected embodiments include a bezel member having a projection positioned between each adjacent pair of outlets to help reduce crosstalk. A releasable latch mechanism may be included that is configured to selectively latch and unlatch the cassette to a patch panel. Embodiments configured for use with fiber optic cables may include a movable connector member. A cable connector may be mounted to the movable connector member to move therewith as a unit. Moving the movable connector member determines an angle of the cable connector relative to the panel. Angles may be selected to reduce stress on a cable connected to the cable connector. In particular, it may be desirable to position the cable connector such that it is orthogonal to the panel.

Claims

1. A device for use with a panel, the device comprising:

a plurality of outlet assemblies arranged in series;

a bezel member housing the outlet assemblies, the bezel member having a plurality of projections, a different one of the plurality of projections extending at least partially between adjacent ones of the plurality of outlet assemblies and at least partially shielding the adjacent outlet assemblies from one other with respect to electrical interference generated thereby; and

a latch mechanism configured to secure the bezel member to the panel.

2. The device of claim 1, wherein the bezel member is constructed from an electrically conductive material.

3. The device of claim 2, wherein the bezel member is constructed from die cast metal.

4. The device of claim 2, further comprising:

a cover member at least partially enclosing the bezel member, the cover member being constructed from an electrically conductive material.

5. The device of claim 4, wherein the cover member is constructed from cold-rolled steel.

6. The device of claim 1, wherein the plurality of communication connectors comprise copper wire connectors.

7. The device of claim 1 for use with the panel comprising a plurality of apertures, wherein the latch mechanism comprises:

a tab positioned to be receivable inside a corresponding one of the plurality of apertures of the panel, and

a pull member configured to be pulled in an unlatch direction, and when so pulled, to release the device from the panel by removing the tab from the corresponding aperture of the panel.

8. The device of claim 1 for use with the panel comprising a plurality of apertures, wherein the latch mechanism comprises a plurality of retractable tabs configured to be selectively extended and retracted,

when extended, the plurality of tabs is receivable inside the plurality of apertures, and when so received, secure the bezel member to the panel, and

the bezel member is releasable from the panel when the plurality of tabs is retracted.

12. The device of claim 8 for use with the selected patching area comprising a plurality of apertures, wherein the latch mechanism comprises a plurality of retractable tabs configured to be selectively extended and retracted,

when extended, the plurality of tabs is receivable inside the plurality of apertures of the selected patching area and when so received, secure the housing subassembly to the panel in the selected patching area, and

the housing subassembly is releasable from the panel when the plurality of tabs is retracted.

9. A device for use with a plurality of connectors, and a panel comprising a plurality of patching areas, the device comprising:

a plurality of outlet assemblies each having an opening configured to receive one of the connectors;

a housing subassembly housing the plurality of outlet assemblies, the housing subassembly comprises a plurality of electrically conductive projections, a different one of the plurality of projections being positioned between adjacent ones of the plurality of outlet assemblies to reduce interference between the adjacent outlet assemblies; and

a latch mechanism configured to releasably secure the housing subassembly to the panel in a selected one of the plurality of patching areas.

10. The device of claim 9 for use with the panel comprising a first support spaced apart from a second support, the first support comprising a first slot, and the second support comprising a second slot, wherein the housing subassembly comprises a bezel member and a cover member,

each of the bezel and cover members is constructed from an electrically conductive material,

the bezel and cover members are in direct contact with one another,

the bezel member comprises the plurality of projections,

the cover member is configured to be positioned between the first and second supports of the panel, and

the cover member comprises first and second outwardly projecting flanges configured to be slid into the first and second slots, respectively.

11. The device of claim 10, wherein the housing subassembly comprises at least one transition member configured to couple the bezel and cover members together.
