Cable pulling grip having toolless removal
View Patent ↗A combination of a pulling grip assembly and a fiber optic cable assembly for installing the fiber optic cable, including: a flexible grip having an open loop region for pull-force engagement and a closed region engaged with the strength member in a fiber optic cable assembly; a first heat shrunk member positioned about a portion of the distal end of the fiber optic cable assembly and the distal end of cable; and a second heat shrunk member positioned about a portion of the closed region of the flexible grip and the proximal end of the fiber optic cable assembly. A method of using the pulling grip assembly and a quick release pulling grip kit for installing fiber optic cable, as defined herein, are also disclosed.
1. A method of installing a pulling grip assembly on a fiber optic cable assembly that includes a cable, the method comprising:
placing a cover sleeve over a portion of the fiber optic cable assembly;
attaching a flexible grip to a strength member of the cable in the fiber optic cable assembly to form the pulling grip assembly, wherein the flexible grip has an open loop region for pull-force engagement and a closed region engaged with the strength member;
heating a first heat shrinkable member that is positioned about a portion of a distal end of the cable and a first end of the cover sleeve to secure the cover sleeve to the fiber optic cable; and
heating a second heat shrinkable member that is positioned about a portion of the closed region of the flexible grip and a second end of the cover sleeve to secure the second heat shrinkable member to a portion of the flexible grip and the cover sleeve.
2. The method of claim 1 wherein the second heat shrunk member includes one or more perforations on the heat shrunk member's end nearest to the open loop region of the grip.
3. The method of claim 1 wherein the second heat shrunk member includes a notch at the junction of the open loop region and the closed region of the pulling grip.
4. The method of claim 1 wherein the second heat shrunk member is positioned about the entire length of the closed region of the flexible grip.
5. The method of claim 1 wherein the flexible grip comprises at least one of an adhesive tape, a flatenable woven tape, a rope, a flat rope, a cord, a wire, a wire cable, or a combination thereof.
6. The method of claim 1 wherein heating the first and second heat shrinkable members is accomplished at from about 65° C. (150° F.) to about 315° C. (600° F.).
7. The method of claim 1 wherein heating the first and second heat shrinkable members is accomplished at from about 148° C. (300° F.) to about 260° C. (500° F.).
8. The method of claim 1 , for installing fiber optic cable, comprising: pulling the fiber optic cable with the end of the pulling grip in an approximately co-linear direction to position the cable in a desired installation location; and removing the pulling grip from the pulling grip assembly by simultaneously pulling on side portions of the open region of the pulling grip in opposing directions and approximately perpendicular to the co-linear pull direction.
9. The method of claim 8 wherein pulling the fiber optic cable with the pulling grip, removing the pulling grip, or both, are accomplished manually or mechanically.
10. The method of claim 8 wherein removing the pulling grip from the pulling grip assembly and fiber optic cable combination is accomplished manually and without the use of any tools.
11. The method of claim 8 wherein removing the pulling grip from the pulling grip assembly is accomplished within about 10 seconds to 5 minutes.
12. The method of claim 1 wherein the cover sleeve comprises a split tube.
13. The method of claim 1 wherein the cover sleeve comprises a mesh cover.
