Abstract

An enclosure for housing and fastening a length of optical cable, the optical cable having an outer sheath and a flexible strength member, includes a fixing element and a retention assembly, the fixing element being adapted for engaging a portion of the outer sheath and the retention assembly being adapted for fastening the flexible strength member. The fixing element and the retention assembly are independent from each other. The retention assembly includes a reel and a reel seat. The reel is adapted to receive at least one turn of the flexible strength member wound thereon and to be inserted without rotation into the reel seat. The reel seat is adapted for housing the reel. The reel seat is shaped at least partially mating the shape of the reel.

First claim

The invention claimed is:

1. An enclosure for housing and fastening a length of optical cable, said optical cable having an outer sheath and a flexible strength member, comprising a fixing element and a retention assembly, said fixing element being adapted for engaging a portion of the outer sheath and said retention assembly being adapted for fastening said flexible strength member,
wherein said fixing element and said retention assembly are independent from each other,
wherein said retention assembly comprises a reel and a reel seat, said reel being adapted to receive at least one turn of the flexible strength member wound thereon and to be inserted without rotation into the reel seat, and said reel seat being adapted for housing the reel,
wherein said reel seat is shaped at least partially mating the shape of the reel,
wherein said reel has a winding path for at least one turn of the flexible strength member,
wherein said reel is adapted to be pressure pushed into the reel seat, and
wherein the reel can be rendered separated from the enclosure.

2. The enclosure of claim 1 , wherein said reel seat is laterally arranged with respect to said outer sheath fixing element.

3. The enclosure of claim 1 , further comprising a base and wherein the reel is integrally formed with the base and can be separated from said base.

4. The enclosure of claim 3 , wherein said reel is connected to a bottom wall of said base by at least a connecting surface which is breakable in order to render said reel a separated element from said enclosure.

5. The enclosure of claim 1 , wherein said reel comprises a transverse passage for housing said flexible strength member.

6. The enclosure of claim 5 , wherein said transverse passage comprises a channel extending along a diameter direction.

7. The enclosure of claim 5 , wherein said transverse passage comprises a through hole extending along a diameter direction.

8. The enclosure of claim 1 , wherein said reel comprises a cylinder body with a lateral surface and comprising a winding path on said lateral surface for said flexible strength member.

9. The enclosure of claim 8 , wherein said reel seat comprises two facing planar lateral walls and two shaped walls designed to penetrate, at least partially, said path so that the reel is retained and the flexible strength member on the reel is prevented from unwinding.

10. The enclosure of claim 9 , wherein one of said two shaped walls comprises a slit for passage of said flexible strength member.

11. The enclosure of claim 1 , wherein said reel comprises a cylinder body with a lateral surface and spokes radially projecting from said lateral surface, wherein said winding path is provided between first spokes and second spokes.

12. The enclosure of claim 11 , wherein said reel seat comprises a circular seat with cavities for housing the free ends of the spokes.

13. The enclosure of claim 12 , wherein said reel seat comprises a stud for engaging a hole of said reel.

14. The enclosure of claim 1 , wherein said reel is a harrow-shaped element with a lateral surface and comprising a winding path on at least a portion of a lateral surface thereof.

15. The enclosure of claim 14 , wherein the harrow-shaped element has a truncated end and a shank.

16. The enclosure of claim 1 , further comprising at least one flexible strength member deflecting wall for properly deflecting the flexible strength member from a longitudinal direction of an optical fiber to a direction deviating from such a direction toward a reel seat.
