US Patent:

56922990, Dec 2, 1997

Filed:

May 30, 1995

Appl. No.:

8/452750

Inventors:

Daniel Francois Daems - Gravenwezel, BE
John Randolph Holman - Atlanta GA
Carney Preston Claunch - Cary NC
Edward Jackson Wilcox - McDonald PA

Assignee:

Raychem Corporation - Menlo Park CA

International Classification:

B23P 600
H01R 4300

US Classification:

29869

Abstract:

A splice closure including a frame having a partition wall to define front and rear access areas for the closure. The frame carries one or more splice trays on a first surface portion making the splices accessible from the front or first access area. A slack storage compartment is provided on the second surface portion. The slack storage compartment includes one or more pairs of opposing sidewalls that define an access opening for the slack that is accessible from the rear access area. An extension member for the frame is disclosed for obtaining greater amounts of slack from the cable, such as for a taut sheath cable splice. A tandem longitudinal arrangement of splice trays is also disclosed and may be used for a taut sheath ring splice or for repairing a severed cable. A method is disclosed for making a taut sheath optical fiber splice to the severed cable.

US Classification:

Abstract:

An in-line splice closure for splicing two hybrid fiber and signal conductor cables includes an outer housing having opposing first and second ends for receiving respective ends of the cables. An organizer tube extends within the outer housing. Electrical connectors are positioned within the organizer tube for connecting signal conductors of the first and second hybrid cables. The splice closure preferably includes at least one optical splice for connecting optical fibers of the first and second cables, and an optical fiber support wrapped around an outer surface of the organizer tube for supporting the at least one optical splice and adjacent optical fiber slack portions. The organizer tube preferably has a predetermined diameter and the optical fiber support preferably supports the optical fiber slack portions so as not to exceed the minimum bend radius. The organizer tube preferably has a longitudinally extending groove in an outer surface portion for receiving buffer tubes of the cables. The optical fiber support may comprise a flexible substrate for supporting the fibers.
