Abstract
A fiber optic pulling grip assembly includes a front grip unit to grip a front end of a mesh of a fiber optic cable, and a rear grip unit to grip a rear end of the mesh. The rear grip includes a sleeve member and a tubular fastener. The sleeve member has an anti-slip portion that has protrusions to increase friction between the anti-slip portion and a rear end of the mesh. The tubular fastener is sleeved around the sleeve member. A cable entry hole of the tubular fastener allows insertion of the fiber optic cable into the sleeve member. The anti-slip portion and the tubular fastener cooperate to clamp therebetween the rear end of the mesh.
Claims5
A fiber optic pulling grip assembly for a fiber optic cable that has an optical fiber unit and a mesh surrounding the optical fiber unit, comprising:
- a front grip unit configured to sleeve around a front end of the fiber optic cable and to grip a front end of the mesh;
- and
- a rear grip unit disposed rearward of said front grip unit and including
- a sleeve member having a sleeve portion, a threaded portion extending integrally and frontally from said sleeve portion, an anti-slip portion extending integrally and frontally from said threaded portion, and a passage extending through said sleeve, threaded and anti-slip portions, said passage being configured to allow insertion of the optical fiber unit, said threaded portion being formed with an outer thread, said anti-slip portion being configured to be sleeved by a rear end of the mesh, said anti-sip portion having an outer surface formed with a plurality of protrusions configured to increase friction between said outer surface and the mesh, and
- a tubular fastener having a tubular portion sleeved around said sleeve member, and an end plate portion transversely connected to a front end of said tubular portion and having a cable entry hole in communication with said passage of said sleeve member, said cable entry hole being configured to allow the fiber optic cable to extend into said passage, said tubular portion having an internal thread threadedly connected to said outer thread of said sleeve member, said anti-slip portion of said sleeve member and said tubular portion cooperating with each other to clamp the rear end of the mesh.
