Abstract

A housing assembly for enclosing and storing cable splices comprises axially spaced end plates defining a storage space and joined by a pair of rigid torque bars. A pair of opposed housing members contoured to enclose the end plates and the storage space are releasably and sealing clamped to each other and to the end plates. A connect panel for supplying connector couplings that receive connectors spliced to the glass fibers is connected to one of the rigid torque bars.

Claims

1. A housing assembly for enclosing and storing fiber optic cable splices comprising:

first and second end plates axially spaced from one another and defining a storage space therebetween;

a pair of opposed housing members contoured to enclose the end plates and the storage space, said housing members being releasably and sealably clamped to each other and to said end plates;

a fiber optic storage receptacle in the storage space; and

,

a fiber optic connect panel in the storage space.

2. The housing assembly as set forth in claim 1 further comprising:

a first rigid bar extending through the storage space with its ends rigidly joined to the end plates and supporting the fiber optic connect panel.

3. The housing assembly as set forth in claim 2 further comprising:

a second rigid bar positioned in spaced apart parallel relationship to the first rigid bar and extending through the storage space with its ends rigidly joined to the end plates, and stabilizing the connect panel which longitudinally extends along the second rigid bar substantially from the first end plate to the second end plate.

4. The housing assembly as set forth in claim 3 wherein the connect panel is "T" shaped.

5. The housing assembly as set forth in claim 4 wherein the "T" shaped connect panel includes an upper section extending along the second rigid bar substantially from the first end plate to the second end plate and a lower section extending along the first rigid bar substantially the length of the fiber optic storage receptacle.

6. The housing assembly as set forth in claim 1 further comprising:

a first rigid bar extending through the storage space and having its ends rigidly joined to the end plates.

7. The housing assembly as set forth in claim 6 further comprising:

a second rigid bar positioned in spaced apart parallel relationship to the first rigid bar and extending through the storage space with its ends rigidly joined to the end plates, the fiber optic storage receptacle joined to the first rigid bar and the connect panel joined to at least one of the first and second rigid bars.

8. The housing assembly as set forth in claim 1 further comprising:

a plurality of connection couplings removably held within the connect panel and each capable of connecting at least two fiber optic cable splices.

9. The housing assembly as set forth in claim 8 further comprising:

a plurality of inserts connectable to the connect panel and each containing the plurality of connector couplings.

10. The housing assembly as set forth in claim 8 further comprising:

a fiber optic cable having a plurality of glass fibers therein and extending into the storage space through one of the end plates;

a second fiber cable having a plurality of glass fibers therein and extending into the storage space through one of the end plates; and

a plurality of connectors each connected to an end of one of a plurality of glass fibers in one of the fiber optic cables and connectable to one of the plurality of connection couplings.

11. The housing assembly as set forth in claim 1 further comprising a panel base from which the connect panel transversely extends.

12. The housing assembly as set forth in claim 1 further comprising:

a plurality of inserts connectable to the connect panel.

13. The housing assembly as set forth in claim 1 further comprising:

a plurality of inserts connectable to the connect panel and containing a plurality of connector couplings.

14. The housing assembly as set forth in claim 1 wherein the fiber optic storage receptacle comprises a storage tray and at least one splice tray in stacked relationship and extending between the pair of rods.

15. The housing assembly as set forth in claim 1 wherein the end plates have a generally circular configuration and said housing members have a generally semi-cylindrical configuration with peripheral clamping flanges extending generally radially therefrom.

16. The housing assembly as set forth in claim 1 wherein said housing members are releasably and sealingly clamped to each other and to said end plates by bolts extending through the clamping flanges.

17. The housing assembly as set forth in claim 1 wherein said housing members and said end plates are molded of a fiber reinforced resinous material.

18. The housing assembly as set forth in claim 1 further comprising glass fiber connection indicia.

19. A housing assembly for enclosing and storing fiber optic cable splices comprising:

a housing defining a fiber optic storage space therein, said housing including a pair of axially spaced end plates and a pair of opposed housing members contoured to enclose the end plates and the storage space;

seal means between the housing members for preventing entry of moisture into the fiber optic storage space;

at least one fiber optic storage receptacle in the storage space; and

,

a connect panel in the storage space.

20. The housing assembly as set forth in claim 19 wherein the connect panel includes means for holding a plurality of inserts.

21. The housing assembly as set forth in claim 20 wherein each insert has a plurality of connection couplings removably held within the insert and each capable of connecting at least two fiber optic cable splices.

22. The housing assembly as set forth in claim 19 further comprising:

a plurality of connection couplings removably held within the connect panel and each capable of connecting at least two fiber optic cable splices.
