Problems solved by technology

Optical cables in the prior art usually use composite aluminum strips, corrugated steel strips, etc. to strengthen the mechanical properties of optical cables. The biggest disadvantage of this strengthening method in use is that it is not ideal in terms of lateral pressure resistance and bending flexibility. In the case of repeated torsion, the optical cable is easy to crack, which affects the performance of the optical cable
In addition, in the communication industry standard YD / T769-2010 of the People's Republic of China, optical cables such as GYXTS and GYXTY are also mentioned. , the role of armored protective optical cable, but its anti-lateral pressure, anti-bending softness needs to be improved

Abstract

The invention belongs to the technical field of cables, and in particular relates to a device for forming a spring armor layer in a spring cable, which includes a bundle tube coil with a central beam tube wound around it, a steel wire coil with a spring wire wound around it, a spring The mold that armor layer forms; The mold that described spring armor layer forms is cuboid shape, has the center hole that runs through left and right sides on this mold, and center hole is positioned at the center of left side and right side, center The hole is a cylindrical hole; on the outside of the center hole, there is a forming hole along the direction of the center hole. The forming hole is composed of a straight hole and a spiral hole connected with the straight hole. The diameter of the straight hole is the same as that of the spiral hole. Large, and neither the straight hole nor the spiral hole communicates with the central hole; the spiral hole is at least a whole spiral; the mold forms a spiral hole during casting. The device in the invention is simple, reliable, low in cost and the production method is easy to learn.

Description

[0001] This application is a divisional application of the invention patent application with the invention name: a spring cable; application number: 201210103179.4; application date: April 7, 2012. technical field [0002] The invention belongs to the technical field of cables, in particular to a spring cable that adopts spring armor to enhance lateral pressure resistance and twist resistance; and a device for forming a spring armor layer. Background technique [0003] In the prior art, optical cables have been widely used in various industries, especially in the technical field of optical signal transmission. Optical cables in the prior art usually use composite aluminum strips, corrugated steel strips, etc. to strengthen the mechanical properties of optical cables. The biggest disadvantage of this strengthening method in use is that it is not ideal in terms of lateral pressure resistance and bending flexibility. In the case of repeated torsion, the optical cable is easy to...
