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

What the invention claimed is:

1. An optical fiber module rack system, comprising:
a rack comprising a base panel, a plurality of partition plates arranged on said base panel, a plurality of accommodation chambers defined within said base panel and separated from one another by said partition plates, each said accommodation chamber defining an opening located in each of opposing front and rear sides thereof, a first sliding groove and a second sliding groove respectively disposed at two opposite sidewalls of each said accommodation chamber and extended to the openings in the front and rear sides of the associating said accommodation chamber, and a stop block located at each of opposing front and rear ends of each said first sliding groove;
a plurality of optical fiber storage boxes respectively mounted in said accommodation chambers of said rack, each said optical fiber storage box comprising a hollow box body, a first optical fiber module mounted in a front side of said hollow box body for the connection of predetermined mating optical fiber connectors, a second optical fiber module mounted in an opposing rear side of said hollow box body and connected to said first optical fiber module for the connection of predetermined mating optical fiber connectors, two guide rails respectively located at two opposite sidewalls of said hollow box body at different elevations and respectively inserted into one respective said first sliding groove and one respective said second sliding groove in one said accommodation chamber of said rack, two elastic retainer strips respectively outwardly extended from opposing front and rear ends of one said guide rail, two hook blocks respectively located at said elastic retainer strips adjacent to the associating said guide rail at an outer side for engagement with one respective said stop block of said rack, and an elongated press member outwardly extended from a front end of the other said guide rail for pressing by an external force to disengage said hook blocks from the respective said stop blocks for allowing removal of the respective said optical fiber storage box from the respective said accommodation chamber of said rack.

2. The optical fiber module rack system as claimed in claim 1 , wherein said rack further comprises two upright side panels respectively extended from two opposite lateral sides of said base panel, and a cover panel supported on said partition plates and fixedly fastened to said upright side panels.

3. The optical fiber module rack system as claimed in claim 1 , wherein said first sliding groove and said second sliding groove are respectively disposed at two opposite sidewalls of each said accommodation chamber at different elevations rack; said guide rails of each said optical fiber storage box are located at the two opposite lateral sidewalls of the associating said hollow box body at different elevations and respectively inserted into said first sliding groove and said second sliding groove in the respective said accommodation chamber so that the elongated press member of each said optical fiber storage box and the adjacent elastic retainer strip of one adjacent said optical fiber storage box are kept at different elevations.

4. The optical fiber module rack system as claimed in claim 1 , wherein each said stop block of said rack defines a beveled outer guide surface at an outer side and a stepped inner abutment surface at an inner side.

5. The fiber module rack system as claimed in claim 1 , wherein each said optical fiber storage box further comprises a storage chamber defined in the hollow box body thereof storage chamber; said first optical fiber module and said second optical fiber module are respectively mounted in the front and rear sides of said hollow box body and exposed out of the respective openings in the opposing front and rear sides of the respective said accommodation chamber of said rack, said first optical fiber module comprising a plurality of first sockets, said second optical fiber module comprising a plurality of second sockets of different designs relative to said first sockets.

6. The optical fiber module rack system as claimed in claim 1 , wherein each said elastic retainer strip of each said optical fiber storage box comprises a conical finger tip at a distal end thereof and a plurality of wave-shaped anti-slip grooves located at an outer side thereof adjacent to said conical finger tip.

7. The optical fiber module rack system as claimed in claim 1 , wherein each said hook block defines a beveled pushing surface that slopes downwardly inwards toward the associating said guide rail and a stepped engagement surface disposed opposite to s aid beveled pushing surface of the respective said hook block.

8. The optical fiber module rack system as claimed in claim 1 , wherein the length of said elongated press member of each said optical fiber storage box is shorter than said elastic retainer strips, said elongated press member comprising a conical finger tip located at a distal end thereof, a plurality of wave-shaped anti-slip grooves located at an outer side thereof adjacent to said conical finger tip, and a reinforcing rib located at an inner side thereof and horizontally extended to the associating said hollow box body.

9. The optical fiber module rack system as claimed in claim 1 , wherein said first optical fiber module of each said optical fiber storage box comprises a plurality of first sockets, each said first socket defining therein a row of parallel mating connection holes, said first sockets being selectively LC or SC connectors for the connection of single-core LC or SC optical fiber connectors.

10. The optical fiber module rack system as claimed in claim 1 , wherein said second optical fiber module of each said optical fiber storage box comprises a plurality of second sockets, each said second socket comprising a mating connection hole extending through two opposite ends thereof, said second sockets being MPO connectors for the connection of 12-core MPO optical fiber connectors.

11. The optical fiber module rack system as claimed in claim 1 , wherein each said optical fiber storage box further comprises a pull handle forwardly extended from a front bottom side of the hollow box body thereof, said pull handle comprising a handle body, two extension arms respectively extended from two opposite lateral sides of said handle body and terminated in the associating said hollow box body.

12. The optical fiber module rack system as claimed in claim 1 , wherein the number of said accommodation chambers of said rack and the number of said optical fiber storage boxes are 8, and the first optical fiber modules and second optical fiber modules of the total 8 pcs of said optical fiber storage boxes are connected for the connection of total 192 cores of LC or SC optical fiber connectors.
