Method and device for bringing optical fiber ribbon of skeleton optical cable into slot

Abstract

The invention provides a method and a device for bringing an optical fiber ribbon of a skeleton optical cable into a slot. The device comprises a cluster die rotating disk and an import die rotating disk which are concentrically arranged at an interval. A skeleton penetrates the two rotating disks and moves forward at a constant speed along the center line of the two rotating disks. An optical fiber ribbon passes through a corresponding cluster die and an import die and then enters the corresponding skeleton slot for moving forward with at a constant speed with the skeleton slot, the cluster die rotating disk and the import die rotating disk slowly rotate along the rotation direction of the skeleton slot, and the optical fiber ribbon corresponding to each skeleton slot gradually enters the slot under the combined action of the traction force and the torsional force, and the lead formed by the rotation traction of the optical fiber ribbon is consistent to the lead of the skeleton slot. The invention can conveniently and rapidly introduce the multi-layer optical fiber ribbon into the skeleton slot, obviously reduces the frictional resistance of the optical fiber into the slot, prevents the optical fiber ribbon from jumping out of the skeleton slot, and solves the problem that the conventional optical fiber ribbon is sprayed with talcum powder polluting the environment for entering the slot, the use is convenient, and the production efficiency and the quality of the skeleton optical fiber ribbon cable are effectively improved.

Description

technical field [0001] The invention relates to a method and a device for bringing an optical fiber into a groove for a skeleton optical cable, in particular to a method and a device for bringing an optical fiber ribbon into a groove during the production process of a skeleton optical cable. Background technique [0002] The skeleton is the cable core of the optical cable, including a skeleton and open skeleton grooves arranged at intervals on the outer periphery of the skeleton. Steel wires or non-metallic reinforcements are installed in the center of the skeleton. The optical fiber ribbon is placed in the skeleton groove, and a layer of water blocking tape is wrapped around the skeleton. The water blocking tape can be longitudinally wrapped with an armored metal layer, and the outermost layer is covered with an outer sheath. Compared with the traditional optical cable in the past, the skeleton optical cable has become an important choice for the distribution section of the...

AI Technical Summary

Problems solved by technology

The above two methods of bringing optical fibers into the groove not only have low processing efficiency, but also have certain problems in processing quality.

Moreover, these two methods of bringing optical fibers into the slots require continuous spraying of lubricating materials such as talcum powder to reduce the adverse effects of friction on optical fiber attenuation, and lubricating materials such as talc powder cause certain pollution to the processing environment
