Abstract

An optical port including: a base capable of being attached substantially parallel to a planar surface; a spool arranged so as to rotate about a shaft, which is substantially perpendicular to the base; an optical cable rolled up into the spool; and a connector. An inner side of the connector is connected inside the port to a first end, referred to as the “inner end”, of the cable. An outer side of the connector is intended to be connected to an outer optical connection plug. The cable is intended to be unreeled out from the port by pulling one second end, referred to as the “outer end”, of the cable. The pulling rotates the spool on the shaft. The connector is secured to the spool and arranged so as to take at least one position outside the radial configuration of the spool.

First claim

The invention claimed is:

1. An optical enclosure comprising:
a base that can be fixed substantially parallel with a planar surface;
a spool arranged to rotate about a shaft which is substantially perpendicular to the base, the spool extending radially from the shaft between a first plane and a second plane;
an optical cable wound in the spool;
a connecting piece, an inner side of which is connected inside the enclosure to a first end of the cable, called the internal end of the cable, an outer side of the connecting piece being intended to be connected to an external optical connection plug;
a removable lid that can cover the base and the spool;
the spool being rotatable on the shaft to enable the cable to be unwound out of the enclosure by pulling a second end of the cable, called the external end of the cable,
wherein the connecting piece is connected to the spool, and is movable between at least:
a position outside a radial continuation of the spool defined between the first and second planes; and
a so-called storage position within the radial continuation of the spool, between the first and second planes, the storage position allowing the lid to cover the base and the spool.

2. The optical enclosure as claimed in claim 1 , wherein the spool comprises a movable part on which the connecting piece is fixed, wherein the movable part is arranged to tilt the connecting piece between at least a position outside the radial continuation of the spool, and a storage position in the radial continuation.

3. The optical enclosure as claimed in claim 2 , wherein the movable part is a flap connected by a hinge to the spool.

4. The optical enclosure as claimed in claim 2 , wherein the movable part is a flexible strip having one end fixed to the spool.

5. The optical enclosure as claimed in claim 2 , wherein the enclosure further comprises a blocking element that can immobilize the connecting piece, when the connecting piece is in the position outside the radial continuation of the spool.

6. The optical enclosure as claimed in claim 1 , wherein the enclosure further comprises a blocking element that can immobilize the connecting piece, when the connecting piece is in the storage position.

7. The optical enclosure as claimed in claim 6 , wherein the blocking element comprises at least one abutment in the base, which can block the connecting piece in the storage position.

8. The optical enclosure as claimed in claim 6 , wherein the blocking element comprises at least one abutment in the lid, blocking the connecting piece in the storage position when the lid covers the base.

9. The optical enclosure as claimed in claim 1 , wherein the cable has a circular, oval or rectangular section.

10. A method of installing an optical enclosure, the enclosure comprising:
a base that can be fixed substantially parallel with a planar surface;
a spool arranged to rotate about a shaft which is substantially perpendicular to the base the spool extending radially from the shaft between a first plane and a second plane;
an optical cable wound in the spool;
a connecting piece, an inner side of which is connected, inside the enclosure, to a first end of the cable, called the internal end of the cable, an outer side of the connecting piece being intended to be connected to an external optical connection plug;
a removable lid that can cover the base and the spool;

the spool being rotatable on the shaft to enable the cable to be unwound out of the enclosure by pulling a second end of the cable, called the external end of the cable,
the method comprising the following acts:
fixing the base on the planar surface;
positioning the connecting piece in a position outside a radial continuation of the spool which is defined between the first and second planes;
unwinding a length of cable by pulling the cable out of the enclosure by the external end of the cable;
after unwinding the cable, positioning the connecting piece in a storage position within the radial continuation of the spool, between the first and second planes, allowing the lid to cover the base and the spool;
fixing the lid on the base when the connecting piece is positioned in the storage position.
