Description
Technical field
The utility model relates to a kind of optical cable, especially a kind of heavily loaded optical fiber trailing cable.
Background technology
At emergency dealing, work high above the ground, deep water is explored and large scale place is shuttled back and forth in the work such as mobile video display shooting tripod head, often need to be broadcasted by cable system to reach corresponding equipment, also need real-time information to return at a distance simultaneously, and send to a little and be put a little between realize real-time communication, realize above-mentioned purpose, one or a few heavy burden cable is not only needed to ensure that large load equipment is sent to safely, one or one group of communication cable is also needed to ensure to be the communication of putting a little and between the point of arrival, because communication cable can not load-bearing, the cable retractable equipment that two covers are roughly the same is often adopted in prior art, generally also pulley structure can be installed in retractable equipment.But the synchronism of this folding and unfolding mode to two cover hawser retractable equipments requires very high, does not slightly note the accident easily occurring that communication cable ruptures, brings great inconvenience to user, and two cover hawser retractable equipments take up room greatly, and cost is high simultaneously.
In order to solve above Problems existing, people are seeking a kind of desirable technical solution always.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, thus provides a kind of heavily loaded optical fiber trailing cable.
To achieve these goals, the technical scheme that the utility model adopts is: a kind of heavily loaded optical fiber trailing cable, comprise shell-like load-bearing kernmantle and be arranged in the communication cable in this shell-like load-bearing kernmantle along its length, described communication cable comprises the optical fiber being positioned at core, be located at the coil of strip spring sheath of outer fiber, be located at the high strength fibre packed layer on described coil of strip spring jacket outer surface, the restrictive coating be located at the steel screen layer on described high strength fibre packed layer outside surface and be located on steel screen layer outside surface, described shell-like load-bearing kernmantle is set on described restrictive coating.
Preferably, described high strength fibre packed layer is the aramid fiber packed layer of aligning structure.
Preferably, the sheathed aramid fiber protective layer with aligning structure on described optical fiber.
The utility model hinge structure has substantive distinguishing features and progress, specifically, a kind of heavily loaded optical fiber trailing cable, communication cable is arranged in shell-like load-bearing kernmantle, the load-bearing of shell-like load-bearing kernmantle is utilized when using, utilize communication cable transmission of information, communication cable and suit load-bearing kernmantle lead to rail and use, a set of hawser retractable equipment can complete the work of folding and unfolding and information transmission, simultaneously because the optical fiber in communication cable easily ruptures in extruding with when stretching, and shell-like load-bearing kernmantle is when Transporting equipment, not only pulling force is very large, and shell-like load-bearing kernmantle on the capstan winch of retractable equipment to communication cable produce extruding force very large, therefore, in order to avoid optical fiber is in extruding and fracture when stretching, the utility model prevents optical fiber extrusion fracture at the coil of strip spring sheath of outer fiber, coil of strip spring jacket outer surface arranges high strength fibre packed layer, high strength fibre packed layer outside surface arranges steel screen layer, prevent communication cable from producing stretcher strain due to drawing stress and then preventing fiber-draw from rupturing, above-mentioned measure protects optical fiber well, restrictive coating on steel screen layer outside surface, restrictive coating can the oversheath made of cable is commonly used in rubber sheath or polymer coating layer or prior art other materials, prevent steel screen layer from wearing and tearing between the inside and outside environment of shell-like load-bearing kernmantle simultaneously to communication cable and carry out an isolation, water proof and dust proof, extend the serviceable life of heavily loaded optical fiber trailing cable.Above-mentioned heavily loaded optical fiber trailing cable is skillfully constructed, simple and reasonable, very easy to use.
Further, high strength fibre packed layer is the aramid fiber packed layer of aligning structure, and tensile strength is high.
Further, the sheathed aramid fiber protective layer with aligning structure on optical fiber, carries out one to optical fiber and retrains and prevent coil of strip spring sheath wearing and tearing optical fiber, protect optical fiber further.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of heavily loaded optical fiber trailing cable in the utility model embodiment.
Fig. 2 is the enlarged drawing at A place in figure.
