Description

A kind of spring optical cable

Technical field

The utility model relates to optical cable technology field, particularly relates to a kind of spring optical cable.

Background technology

Along with urbanization process is progressively accelerated, city size constantly expands, urban population sharply increases, the demand of optical cable is also got more and more, pattern is also continuous change, and indoor optical cable also becomes main product, along with improving constantly of quality of life, people are more and more partial to the house of small apartment, compact, the main points of how to save space and how to allow the room people of also becoming more attractive in appearance pay close attention to.

At present, circuit component generally uses concealed wire, and optical cable often need be reserved in new clothes optical cable indoor on wall, use length due to optical cable is difficult to accurately calculate, so optical cable can be caused to stay long easily bending impaired and take up room, that stays is too short, and when secondary utilizes, length can not meet the problem of use.

Utility model content

The purpose of this utility model is to provide a kind of spring optical cable, to solve the above problems.

In embodiment of the present utility model, provide a kind of spring optical cable, comprising: optical fiber, tight sleeve layer, nonmetal tensile elements and outer jacket, optical fiber is flexible optical fibre, is inlaid with spring steel wire in outer jacket, and spring steel wire is embedded in the outside of outer jacket along the hand of spiral.

Further, the diameter of spring steel wire is 0.5mm.

Further, nonmetal tensile elements is aramid yarn.

Further, tight sleeve layer is overlying on outside optical fiber, and tight sleeve layer is evenly provided with 4-8 root aramid yarn outward.

Further, outer jacket is fire-retardant outer jacket.

Compared with prior art the beneficial effects of the utility model are: by using flexible optical fibre and inlay spring steel wire in outer jacket, avoid optical fiber long bending impaired, save space, can reserve the needs that enough length uses to meet secondary.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of spring optical cable of the utility model;

Fig. 2 is the using state schematic diagram of a kind of spring optical cable of the utility model.

Embodiment

Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.

Shown in ginseng Fig. 1 and Fig. 2, Fig. 1 is the structural representation of a kind of spring optical cable of the utility model; Fig. 2 is the using state schematic diagram of a kind of spring optical cable of the utility model.

In the present embodiment, a kind of spring optical cable, comprise: optical fiber 1, tight sleeve layer 2, nonmetal tensile elements 3 and outer jacket 5, optical fiber 1 is flexible optical fibre (bend insensitive fiber), be inlaid with spring steel wire 4 in outer jacket 5, spring steel wire 4 is embedded in the outside of described outer jacket 5 along the hand of spiral.

The optical cable that the present embodiment provides is a kind of indoor spring optical cable with good retractility and style-ability.Steel wire is placed on the outside spiral of spring optical cable, avoid the phenomenon in the serious adduction of the stretching rear steel wire of optical cable, steel wire fixed effect better, there will not be stretching nonrecoverable phenomenon, substantially reduce optical fiber repeatedly bending impaired in optical cable, ensure that the communication quality of optical cable, save space simultaneously, the needs that enough length uses to meet secondary can be reserved.

In the present embodiment, the diameter of spring steel wire is 0.5mm, and contractility appropriateness, cost is lower.

In the present embodiment, nonmetal tensile elements 3 is aramid yarn, and aramid yarn can strengthen optical cable tension stress, improves optical cable flexibility, can alleviate optical cable weight simultaneously, reduces cable size, constructability.

In the present embodiment, tight sleeve layer 2 is overlying on outside optical fiber 1, and tight sleeve layer 2 is outer is evenly provided with 4-8 root aramid yarn 3.

In the present embodiment, outer jacket 5 adopts fire-retardant outer jacket, reduces potential safety hazard.

A series of detailed description listed is above only illustrating for feasibility embodiment of the present utility model; they are also not used to limit protection domain of the present utility model, all do not depart from the utility model skill equivalent implementations of doing of spirit or change all should be included within protection domain of the present utility model.

To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.

In addition, be to be understood that, although this instructions is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of instructions is only for clarity sake, those skilled in the art should by instructions integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
