Abstract

An optical fiber cable management panel includes drawer assemblies, each including a drawer slidable within a chassis. The drawer assemblies are secured together by a bracket that includes an interlock arrangement with the chassis. Such an interlock arrangement includes a non-threaded stud engaging a hole. Radius limiters may be part of the drawer assembly and include a cable entry aperture have a closed perimeter and a flared cable guide surface around most of, and preferably all of, the closed perimeter to allow for the entry of cables from all directions. A control mechanism controls movement of the radius limiter relative to the drawer assembly. The control mechanism includes a rotating member that has an axis of rotation transverse to the slidable motion of the radius limiter and normal to the radius limiter.

Claims

1. A radius limiter for an optical fiber cable management panel;

the radius limiter comprising;

(a) a frame piece defining a curved trough section;

(b) a cover member attached to the frame piece and positionable in an open position and a closed position, the cover member being sized to cover only part of the trough section when positioned in the closed position; and

(c) a bell-mouth structure that defines a trough entry into the curved trough section of the frame piece, the bell-mouth structure including an outwardly flared cable guide surface;

(d) wherein the outwardly flared cable guide surface circumscribes only part of the perimeter of the trough entry when the cover member is positioned in the open position, and wherein the outwardly flared cable guide surface circumscribes the entire perimeter of the trough entry when the cover member is positioned in the closed position.

2. The radius limiter of claim 1, wherein a portion of the bell-mouth structure is carried by the cover member.

3. The radius limiter of claim 2, wherein the cover member includes a finger having a first end and a second end, the first end being pivotally secured to the frame piece.

4. The radius limiter of claim 3, wherein the portion of the bell-mouth structure is attached to the finger adjacent to the second end of the finger.

5. The radius limiter of claim 1, further including a latch arrangement that releasably secures the cover member in the closed position.

6. The radius limiter of claim 1, wherein the cover member is attached to the frame piece by a snap-fit connection.

7. The radius limiter of claim 6, wherein the snap-fit connection pivotally secures the cover member to the frame piece.

8. The radius limiter of claim 6, wherein the snap-fit connection includes a pair of tabs that snap-fit around a frame piece member at a hinge point.

9. The radius limiter of claim 1, wherein the curved trough section is defined by first and second continuously curved walls.

10. The radius limiter of claim 1, wherein the frame piece is configured to mount to a sliding drawer, the frame piece including receiving apertures sized to receive tabs of a control mechanism that provides synchronized sliding movement of the radius limiter relative to the drawer.

11. The radius limiter of claim 10, wherein the control mechanism is positioned within an elongated slot formed in a sidewall-free construction of the drawer, the radius limiter being located above the control mechanism when mounted to the sliding drawer.

12. The radius limiter of claim 1, wherein the frame piece is configured to mount to a sliding drawer assembly, the frame piece and the bell-mouth structure being oriented such that when two sliding drawer assemblies are interconnected to one another by a mounting bracket, the bell-mouth structures of each drawer-mounted radius limiter faces toward an open-side of the respective sliding drawer assembly to accommodate cable entry and exit.
