Rat-proof optical cable capable of being recognized easily, and production technology and die for optical cable

Abstract

The invention discloses a rat-proof optical cable capable of being recognized easily, and a production technology and die for an optical cable, and belongs to the technical field of optical cables. The invention aims at solving problems that a conventional optical cable is poor in rat-proof performance, and a mark of the optical cable is worn after long-time use, and cannot be recognized. The exterior of a cable core of the optical cable is sequentially provided with a longitudinal coating steel belt, a polyethylene sheath, and a nylon sheath, wherein the exterior of the nylon sheath is provided with a recognition projection. The polyethylene sheath and the nylon sheath employ a double-head sheath production device, and there is a grafting agent in the material of the polyethylene sheath.The optical cable is small in size, is light in weight, is simple and convenient for reconstruction, is easy to recognized and is high in rat-proof performance.

Description

technical field [0001] An optical cable and its production process and mold belong to the technical field of optical cable, and mainly relate to an easily identifiable anti-rat optical cable, a production process of the optical cable and a production mold. Background technique [0002] The current nylon anti-rodent optical cable is hard and smooth due to the characteristics of the nylon sheath itself, which leads to poor effect of conventional inkjet printing to distinguish the information of the optical cable, and the printing is often wiped off during the construction process, resulting in follow-up maintenance. Sometimes it is impossible to identify the ownership of the optical cable, such as the optical cable of China Telecom, China Mobile or China Unicom. At the same time, because the nylon sheath layer of the optical cable is very hard, hot embossing cannot effectively leave a clear and identifiable mark on the surface of the optical cable. Because the nylon layer and ...

Problems solved by technology

[0002] The current nylon anti-rodent optical cable is hard and smooth due to the characteristics of the nylon sheath itself, which leads to poor effect of conventional inkjet printing to distinguish the information of the optical cable, and the printing is often wiped off during the construction process, resulting in follow-up maintenance. Sometimes it is impossible to identify the ownership of the optical cable, such as the optical cable of China Telecom, China Mobile or China Unicom. At the same time, because the nylon sheath layer of the optical cable is very hard, hot embossing cannot effectively leave a clear and identifiable mark on the surface of the optical cable.

Because the nylon layer and the polyethylene sheath layer of the nylon rodent-proof optical cable are generally produced by co-extrusion, the use of color stripes to distinguish is not only difficult in the process, but also has the risk of peeling off the nylon layer if the color stripes fall off.
