Abstract

Apparatus for securing a fiber optic cable in an enclosure includes a clip slideably mounted on a bracket. The cable strength member is clamped to the bracket in the position such that little or no bending of the strength member is necessary. A physical stop on the clip ensures that the strength member will not intrude into the splicing area over time.

Claims

1. Apparatus for securing a fiber optic cable having a rod-like rigid reinforcing member in an enclosure, comprising:

(a) an enclosure for holding optical splices or connectors, the enclosure having an outer wall through which optical cables enter the enclosure;

(b) a support member mounted in the enclosure, the support member extending parallel to the outer wall through which optical fibers enter; and

,

(c) securing means for securing a rod-like rigid reinforcing member at any of a plurality of points on the support member.

2. Apparatus as recited in claim 1, further comprising a physical stop limiting enclosure penetration by a rod-like rigid cable reinforcing member to the area between the physical stop and said wall.

3. Apparatus for securing a fiber optic cable having a rod-like rigid reinforcing member in an enclosure, comprising:

(a) an enclosure for holding optical splices or connectors, the enclosure having an outer wall through which optical cables enter the enclosure;

(b) a support member mounted in the enclosure, the support member extending parallel to said outer wall;

(c) a securing means slideably mounted on the support member for securing a rod-like cable reinforcing member without appreciable bending of the cable reinforcing member; and

,

(d) a physical stop limiting enclosure penetration by the rod-like cable reinforcing member to the area between the physical stop and said wall.

4. Apparatus for securing a fiber optic cable having a rod-like rigid support member in an enclosure, comprising:

(a) an enclosure for holding optical splices or connectors, the enclosure having an outer wall through which optical cables enter the enclosure;

(b) a bracket mounted in the enclosure, the bracket extending parallel to the outer wall through which optical fibers may enter;

(c) a clip comprising a plate and first and second legs mounted perpendicular to the plate;

(d) mounting means slideably mounting the clip to the plate such that the legs, the plate, and the bracket delimit a passage having first and second exits for receiving a rod-like rigid support member; and

,

(e) a physical stop blocking the passage exit farther away from said outer wall than the other exit.

5. Apparatus as recited in claim 4, the bracket having a slot therein coextensive with said outer wall and the mounting means comprising a bolt penetrating the slot.

6. Apparatus as recited in claim 5, further comprising two nuts and two washers between the nuts threaded by the bolt.

7. Apparatus as recited in claim 4, the physical stop comprising a lip mounted to the clip.
