Abstract

A rotatable routing guide assembly for fiber optic cables routed in a fiber optic equipment shelf is disclosed. The assembly comprises a guide portion, an attachment feature and a keyed receiver. The guide portion has a bottom, a top, a deformable first wall, a deformable second wall and a third wall forming a plurality of segments, and is configured to receive fiber optic cables of different sizes by different ones of the plurality of segments. The attachment feature removably attaches the guide portion to the shelf. The attachment feature has a first tab forming a first notch with the guide portion, and a second tab forming a second notch with the guide portion. The keyed receiver is located in the shelf and has a lip extending partially around an interior edge. The lip is received in at least one of the first notch and the second notch and friction fit between at least one of the first tab and the second tab and the guide portion.

10. The rotatable routing guide of claim 9, wherein the first tab is configured to be received by a first tab slot in the mounting surface and the second tab is configured to be received by a second tab slot in the mounting surface.

11. The rotatable routing guide of claim 8, wherein the first tab is resilient such that a portion of the mounting surface is received in a notch formed between the first tab and the guide portion, and wherein the portion of the mounting surface is friction fit between the guide portion and the first tab with the first tab biasing the portion of the mounting surface against the guide portion, and wherein the biasing allows for the positioning of the rotatable routing guide in selected multiple positions while maintaining the friction fit.

12. The rotatable routing guide of claim 1, wherein the guide portion has a plurality of routing segments.

13. The rotatable routing guide of claim 1, wherein the force is due to the attachment feature applying a bias to the guide portion when the rotatable routing guide is removably attached to the mounting surface.

14. The rotatable routing guide of claim 1, wherein the guide portion has a third wall between the first wall and the second wall, wherein one end of the third wall is attached to and extends from the bottom, and wherein another end of the third wall is attached to and extends from a center portion of the top.

15. The rotatable routing guide of claim 14, wherein the first wall is attached to a first portion of the top, and the second wall is attached to a second portion of the top.

16. The rotatable routing guide of claim 15, wherein the gap between the top and the at least one of the first wall and the second wall comprises a first gap formed between the first portion of the top and the center portion of the top, and a second gap formed between the second portion of the top and the center portion of the top.

17. The rotatable routing guide of claim 16, wherein force due to the attachment feature applying a bias to the guide portion when the rotatable routing guide is removably attached to the mounting surface, deforms the first wall into contact with the top, thereby closing the first gap, and deforms the second wall into contact with the top, thereby closing the second gap.

18. The rotatable routing guide of claim 1, wherein the attachment feature comprises a tab having a protrusion, and wherein the mounting surface comprises a plurality of detents, and wherein when the rotatable routing guide rotates, the protrusion positions in one of the plurality of detents releasably locking the rotatable routing guide at a position corresponding to the detent.
