Problems solved by technology

[0003] The outer diameter of traditional photoelectric composite cables generally exceeds 10mm, and the cable itself is very hard, which cannot be used repeatedly, and it is also very difficult to deploy
This brings great inconvenience to construction and use

Embodiment Construction

[0021] Refer to attached figure 1 , a photoelectric composite cable for towing is composed of multiple silver-plated conductors 4, tight-buffered optical fibers, polyester tape 6, spiral stainless steel hose 7, aramid twisted layer 8, and polyurethane sheath 9. The tight-buffered optical fiber is coated with a layer of silicone rubber buffer layer 2 on the optical fiber 1, and a layer of tight-buffered layer 3 of nylon material is arranged outside the silicone rubber buffer layer. High-temperature fluoroplastics are extruded outside the silver-plated wire 4 as the insulating sheath 5 . The tight-buffered optical fiber is placed in the center of the silver-plated wire 4, thus forming the core of the photoelectric composite cable—the cable core. The tight-buffered optical fiber and the silver-plated wire 4 are twisted into a cable core in the form of S twisting, and the polyester tape 6 is used to bind The cable core is wrapped and fixed, a spiral stainless steel hose 7 is arra...

Abstract

The invention relates to an electro-optic compound cable for towing, which is an electro-optic compound cable capable of retracting and releasing repeatedly in special occasions, and used for transmitting optical signals and electrical signals. The cable core is formed by twisting high temperature silver-plated leads and optical fiber, and is protected by spiral metal hose at outside, and polyurethane material is extruded outside the steel tube. The cable is composed of a plurality of silver-plated leads, tight tube optical fiber, polyester belting, a spiral stainless steel hose, an aramid fiber twisted layer and a polyurethane jacket; the tight tube optical fiber and the silver-plated leads are twisted into the cable core in an S twisting form, the cable core is wrapped and fixed by the polyester belting, the spiral stainless steel hose is arranged outside the polyester belting, the aramid fiber twisted layer is arranged outside the spiral stainless steel hose, and the polyurethane jacket is extruded outside the aramid fiber twisted layer.

Description

technical field [0001] The invention relates to a photoelectric composite cable for towing and a manufacturing method thereof, which relates to a photoelectric composite cable which is repeatedly retractable and retractable in special occasions, and is used for transmitting optical signals and electrical signals at the same time. The cable core is composed of high-temperature silver-plated wires and optical fibers, which are protected by a spiral metal hose outside the cable core, and polyurethane material is extruded outside the steel pipe. Background technique [0002] Optical cable is an effective means of large-capacity, long-distance transmission. In many occasions, we need to transmit both electrical signals and optical signals, which requires photoelectric composite cables. In view of some occasions, the outer diameter of the photoelectric composite cable is required to be very small, but also to meet the very large tensile requirements. At the same time, due to the ...
