Abstract

An optical fiber module rack system includes a rack including multiple accommodation chambers, opposing first and second sliding grooves located in each accommodation chamber, and a stop block located at each of opposing front and rear ends of each first sliding groove, and optical fiber storage boxes each including a box body mounted in one respective accommodation chamber, a first optical fiber module and second optical fiber module mounted in opposing front and rear sides of box body and connected together, two guide rails located at two opposite lateral sidewalls of box body and respectively coupled to first sliding groove and second sliding groove of respective accommodation chamber, two elastic retainer strips respectively extended from opposite ends of one guide rail and provided with a respective hook block for engagement with one respective stop block, and elongated press member extended from other guide rail for pressing by external force to disengage hook blocks from respective stop blocks for allowing removal of optical fiber storage box out of respective accommodation chamber.

First claim

The invention claimed is:

1. An optical fiber module rack system comprising:
a plurality of optical fiber storage boxes; and
a rack comprising a plurality of adjacent accommodation chambers for receiving the respective ones of the plurality of optical fiber storage boxes, wherein
each of the plurality of accommodation chambers comprises a first sliding groove and a second sliding groove respectively being formed along opposite sides of respective one of the accommodation chambers at different elevations from one another,
each of the optical fiber storage boxes comprises a body, a first guide rail and a second guide rail, and
the respective first and second guide rails are formed along opposite sides of the body at different elevations from one another and are engaged with corresponding first and second sliding grooves of the accommodation chambers.

2. The optical fiber module rack system of claim 1 wherein:
each of the optical fiber storage boxes further comprises respective first and second optical fiber modules;
the first optical fiber module is mounted on one end of the body; and
the second optical fiber module is mounted on an opposite end of the body for connection to the first optical fiber module.

3. The optical fiber module rack system of claim 1 wherein:
at least one end of the first guide rail comprises an elastic retainer strip, a hook block, and an elongated press member; and
at least one end of the second guide rail comprises an elastic retainer strip, a hook block, and an elongated press member.

4. The optical fiber module rack system of claim 3 wherein:
at least one end of the first sliding groove comprises a stop block;
at least one end of the second sliding groove comprises a stop block; and
corresponding stop blocks and hook blocks are engaged with one another when the optical fiber storage boxes are retained by the respective accommodation chambers.

5. The optical fiber module rack system of claim 4 wherein the elongated press member of the first guide rail is shorter than the elastic retainer strip of the second guide rail so that, when pressing the elastic retainer strip of the second guide rail, the elastic retainer strip of the second guide rail is free from interference of the elongated press member of the first guide rail of an adjacent optical fiber storage box received in an adjacent accommodation chamber of the rack.

6. The optical fiber module rack system of claim 4 wherein:
the hook block of the first guide rail can be abutted against the stop block of the first sliding groove, and
the elastic retainer strip of the first guide rail can be elastically deformed to allow movement of the hook block of the first guide rail over the stop block of the first sliding groove to enable the optical fiber storage box to be removed from the accommodation chamber.

7. The optical fiber module rack system of claim 4 wherein the stop block of the first sliding groove defines a beveled outer guide surface at an outer side and a stepped inner abutment surface at an inner side.

8. The optical fiber module rack system of claim 4 wherein the first and second guide rails and the first and second sliding grooves are structurally configured such that corresponding ones of the hook blocks and the stop blocks can be disengaged from one another by pressing upon the respective elastic retainer strips of the guide rails and such that selected ones of the optical fiber storage boxes can be removed from the respective accommodation chambers.

9. The optical fiber module rack system of claim 1 wherein:
each end of the first guide rail comprises an elastic retainer strip, a hook block, and an elongated press member; and
at least one end of the second guide rail comprises an elastic retainer strip, a hook block, and an elongated press member.

10. The optical fiber module rack system of claim 9 wherein:
each end of the first sliding groove comprises a stop block;
at least one end of the second sliding groove comprises a stop block; and
corresponding ones of the accommodation chamber stop block and the optical fiber storage box hook block are engaged with one another when each of the plurality of optical fiber storage boxes is retained by the respective accommodation chambers.

11. The optical fiber module rack system of claim 4 wherein the elongated press member of the first guide rail is shorter than the elastic retainer strip of the second guide rail so that, when pressing the elastic retainer strip of the second guide rail, the elastic retainer strip of the second guide rail is free from interference of the elongated press member of the first guide rail of an adjacent optical fiber storage box received in an adjacent accommodation chamber of the rack.

12. The optical fiber module rack system of claim 1 wherein:
each end of the first guide rail comprises an elastic retainer strip, a hook block, and an elongated press member; and
each end of the second guide rail comprises an elastic retainer strip, a hook block, and an elongated press member.

13. The optical fiber module rack system of claim 12 wherein:
each end of the first sliding groove comprises a stop block;
each end of the second sliding groove comprises a stop block; and
corresponding ones of the accommodation chamber stop blocks and the optical fiber storage box hook blocks are engaged with one another when each of the plurality of optical fiber storage boxes is retained by the respective accommodation chambers.

14. An optical fiber module rack system comprising:
a plurality of optical fiber storage boxes; and
a rack comprising a plurality of adjacent accommodation chambers for receiving the respective ones of the plurality of optical fiber storage boxes, wherein
each of the plurality of accommodation chambers comprises a first sliding groove and a second sliding groove respectively being formed along opposite sides of respective one of the accommodation chambers at different elevations from one another,
each of the optical fiber storage boxes comprises a body, a first guide rail and a second guide rail, and
the respective first and second guide rails are formed along opposite sides of the body at different elevations from one another and are engaged with corresponding first and second sliding grooves of the accommodation chambers;
each of the optical fiber storage boxes further comprises respective first and second optical fiber modules;
the first optical fiber module is mounted on one end of the body;
the second optical fiber module is mounted on an opposite end of the body for connection to the first optical fiber module;
at least one end of the first guide rail comprises an elastic retainer strip, a hook block, and an elongated press member; and
at least one end of the second guide rail comprises an elastic retainer strip, a hook block, and an elongated press member.

15. The optical fiber storage box of claim 14 wherein an elongated press member of the first guide rail is shorter than an elastic retainer strip of the second guide rail at a common end of the body to avoid interference when pressing the elastic retainer strip.

16. An optical fiber storage box comprising:
a body;
a first guide rail;
a second guide rail; and
respective first and second optical fiber modules, wherein
the respective first and second guide rails are formed along opposite sides of the body at different elevations from one another,
