The cross sectional representation of a kind of optical cable that Fig. 1 provides for the utility model embodiment.
Embodiment
Technical scheme in the utility model is understood better in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the utility model protection.
See Fig. 1, a kind of optical cable that the utility model embodiment provides, comprises cable core 1 and the sheath 2 being coated on described cable core;
Described cable core 1 comprises from inside to outside successively: as heart yearn optical fiber 10, transparent covering 11 and there is close-burning glue-line 12.
Wherein, described sheath 2 pairs of cable cores 1 have protective effect, can prevent the infringement to cable core such as external environment rainwater, high temperature, fire, can prevent optical fiber from fractureing in optical cable laying process.
As the optical fiber 10 of optical cable component wire for signal transmission, optical fiber described in the present embodiment adopts true qualities optical fiber, water white transparency.
Described transparent covering 11 is coated on core fiber 10, presents transparent.On the one hand; described transparent covering 11 pairs of core fiber 10 play a protective role; on the other hand; transparent covering 11 is also for adjusting the diameter dimension of cable core 1; the diameter dimension of cable core is adjusted by the thickness changing transparent covering 11; make the diameter dimension of cable core meet standard-required, can match with the interface of wiring unit.
The outermost layer of described cable core 1 has close-burning glue-line 12, for when house wiring by bonding fiber at wire location place.
Optical cable described in the present embodiment is when accessing house wiring, and concrete operations are: the sheath of optical cable is peelled off after introducing indoor by optical cable, and remaining cable core, is then bonded in wire location place by the outermost glue-line of cable core by cable core, so carries out house wiring.
Optical cable described in the present embodiment, its optical fiber and transparent covering all present transparent, cable core are presented transparent.Therefore, when house wiring, transparent cable core ratio is easier to and surroundings, has the feature of " stealth ", thus can reduce the impact of cable runs on interior decoration aesthetics.
Preferably, in the present embodiment, described in there is close-burning glue-line 12 for hot melt adhesive layer.Hot melt adhesive (English name: HotGlue) is a kind of plastic bonding agent, and in certain temperature range, its physical state changes with temperature change, and chemical characteristic is constant, and it is nonpoisonous and tasteless.Hot melt adhesive is heated to uniform temperature and can melts, and is in a liquid state, and has certain mobility and stickiness, again becomes solid-state after the cooling period.
Described optical cable arranges hot melt adhesive layer at the outermost layer of cable core, and hot melt adhesive layer has stickiness after heating and melting, utilizes its stickiness cable core can be bonded in wire location place, cable core can be fixed after cooling.
Preferably, described hot melt adhesive layer adopts EVA type hot melt adhesive layer, and adopt the EVA type hot melt adhesive produced by Mitsui to be formed, its raw material is ethylene-vinyl acetate copolymer.This hot melt adhesive can repeated multiple times melting, and the good characteristic such as be not clamminess after having low crystallization, high fillibility, low Young modulus, high ductibility, fast cooling, cooling.
In the present embodiment, described transparent covering 11 adopts polyacrylic resin covering, and polyacrylic resin covering has transparent, resistant to elevated temperatures feature, can bear high temperature during hot melt adhesive heating and melting.Energy available protecting optical fiber, prevents high temperature to the damage of optical fiber.
When cable wiring manufacture, first the sheath of optical cable is peelled off, remaining transparent cable core, use hot melt gun by outer field for cable core hot melt adhesive layer heating and melting, then cable core is bonded in wire location place.Therefore, the optical cable with " stealth " feature described in the present embodiment, at the outermost layer of cable core, glue-line is set, the method of glue is cohered compared to adopting manual application when cable wiring manufacture, can ensure that glue-line is even, bonding is even, can ensure that cable runs is neat, attractive in appearance, and easy to operate, can lifting construction efficiency.
A kind of optical cable that the another embodiment of the utility model provides, on the basis of above-described embodiment, described sheath 2 is transparent sheath, in described transparent sheath 2, be provided with transparent reinforcement 3.
Therefore, its cable core 1 of optical cable described in the present embodiment and external jacket 2 all transparent, optical cable entirety is presented transparent, when optical cable laying, no matter indoor or outdoor, optical cable all than being easier to and surroundings, has the feature of " stealth ", can be reduced in greatest extent visually on the impact of surrounding environment, be therefore more easily easily accepted by a user and use.
Preferably, in the present embodiment, the sheath 2 of described optical cable adopts transparent pvc sheath, is made up of Polyvinylchloride, has feature that is transparent, fire-retardant, waterproof, effectively can protect internal optical fiber.
Described transparent reinforcement 3 preferably adopts organdy resin reinforcement, and adopt organdy resin to make, it presents transparent, has the feature of high strength, can ensure toughness and the intensity of described optical cable, effectively prevents from being fractureed when laying.
In the present embodiment, the xsect of the sheath 2 of described optical cable is butterfly, and namely described optical cable is butterfly optical cable.Shown in Figure 1, in described butterfly sheath 2, be provided with two symmetrical reinforcements 3.
Optical cable described in the present embodiment; its outer protective sleeve not only plays the protective effect to inner cable core; and sheath makes the interface of described optical cable and wiring unit match, more easily directly can be connected with wiring unit and introduce indoor, be convenient to " the indoor access " of optical cable.
When described optical cable access is indoor, optical cable is directly introduced indoor by outdoor wiring unit, when house wiring is constructed, the sheath of optical cable is peelled off, use the outer field hot melt adhesive layer of hot melt gun heating and melting cable core, make it have viscosity, then cable core is bonded in wire location place.Can clean wire location place in advance before bonding, the impact on hot melt adhesive viscosity such as reduction dust.Optical cable described in the present embodiment can be arranged in indoor wall linea angulata, door window side etc., minimally can bother resident family, improves the aesthetics of interior decoration.
Therefore, optical cable described in the present embodiment achieves " outdoor access, house wiring ", efficiently solves the problem of conventional cable " difficulty of registering one's residence ".To the deployment of broadband network, there is very important practical significance.
It should be noted that, each embodiment in this instructions all adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar part mutually see.
Above optical cable provided by the utility model is described in detail.Apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
