Device for keeping cabling pitch of layer-stranded cable stable

Abstract

The invention relates to a device for keeping cabling pitch of a layer-stranded cable stable. The device is formed by a support, a support rods and plastic wheel sets. The plastic wheel sets comprise an upper plastic wheel set and a lower plastic wheel set, which are oppositely arranged. The upper plastic wheel set is slidbly arranged on an upper vertical plate of the support through the upper support rod; the lower plastic wheel set is slidbly arranged on a lower vertical plate of the support through the lower support rod; and a channel for allowing optical cables to pass is arranged between the upper plastic wheel set and the lower plastic wheel set. The device is simple in structure, convenient to produce, simple to operate and low in cost, and effectively prevents the case that the use effect of the finished product is influenced due to damage of the structure of the optical cable since the cabling pitch is easy to change, so that the cabling pitch is allowed to be stable; and the device keeps the cabling pitch of the layer-stranded cable stable efficiently, improves product quality, is economic and efficient and is suitable for wide application and use.

Description

technical field [0001] The invention belongs to the field of optical cable processing, and relates to the cabling process of the layer-stranded optical cable, in particular to a device for maintaining the stable pitch of the layer-stranded optical cable. Background technique [0002] Stranded fiber optic cable is formed by twisting a plurality of sleeves containing optical fibers around a central strengthening member to form a round core. The metal or non-metallic strengthening member is located in the center of the cable, and the loose tubes accommodating optical fibers are arranged around the strengthening member. Optical fiber loose tube is wound on the central strength member at a certain pitch, generally FRP is extruded and the inner sheath is extruded, and then wrapped with suitable spun yarn according to the required tensile strength, and then extruded into PE or AT jacket. [0003] When the stranded optical cable works with a large span and a large sag, the pitch of...

AI Technical Summary

Problems solved by technology

However, in the existing technical process, it is difficult to maintain the stability of the cable pitch. It can be overcome by fixing the loose tube on the central strength member and the dry cable core with a suitable method, such as rolling the cable after cable , but the pressure is not easy to control, it is easy to damage the optical cable, affect the yield, and the work efficiency is low
