In another kind of preferred implementation, when the waterstop of described skeleton cable indulges bag, be also provided with the second bundle yarn between the metal tape of described waterstop and described skeleton cable, described second bundle yarn is wound around along the radial direction of described skeleton.Described second pricks the described waterstop that yarn can bundle fixing vertical bag, and prevent in process of production or coiling in the process that tool is wound around, described waterstop relaxes, and better improves the water resistance of this skeleton cable.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of skeleton cable in prior art;
Fig. 2 is the structural representation of a kind of embodiment of skeleton cable provided by the utility model.
Embodiment
Core of the present utility model is to provide a kind of skeleton cable, and this skeleton cable effectively can improve the waterproof ability of self, and then improves the serviceable life of self.
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 2, Fig. 2 is the structural representation of a kind of embodiment of skeleton cable provided by the utility model.
In a kind of embodiment, skeleton cable wrap provided by the utility model is drawn together reinforcement 3, skeleton 4, fibre ribbon 2 and is had the filling material 9 of fire resistance characteristic.Reinforcement 3 inserts in the axially extending bore of skeleton 4, fibre ribbon 2 is positioned at the skeleton grooves of skeleton 4, after fibre ribbon 2 imports skeleton grooves, certain space can be left in skeleton grooves, for improving the withstand voltage of this skeleton cable and impact resistance, filling material 9 is filled in the space of skeleton grooves, and fibre ribbon 2 can be sealed in skeleton grooves by filling material 9, effectively prevent water vapor from entering skeleton grooves corrosion fibre ribbon 2, and then the effective waterproof ability improving this skeleton cable.
Filling material 9 is specifically as follows ointment filling material 9, ointment is divided into again fine cream and cable cream, because cable cream can cause slight damage to fibre ribbon, therefore the filling material 9 of this skeleton cable adopts fine cream filling material 9, fine cream filling material 9 can be better compatible with fibre ribbon 2, fine cream filling material 9 belongs to cold applied filled composite, flow-like in thickness, when fine cream filling material 9 is filled into after in the space of skeleton grooves, the fine cream filling material 9 of flow-like can, by fibre ribbon 2 and isolate from outer air, avoid water vapor to enter skeleton grooves corrosion fibre ribbon 2.In addition, because fine cream filling material 9 has fluidity, therefore the space proportion shared by fibre ribbon 2 can not be impacted, both can not affect resistance to compression and the shock resistance of fibre ribbon 2 itself, when this skeleton cable is subject to percussive action, buffer action can also be played to fibre ribbon 2.
This skeleton cable can further include waterstop 5, flows into skeleton grooves for stoping water body.Waterstop 5 is the nonwoven fabrics waterstop 5 that surface scribbles water-proofing powder, and waterstop 5 is in strip, and the axis along skeleton 4 is wrapped up, and axially the parcel mode of vertical bag can save the material of waterstop 5, and is convenient to dismounting.
The skeleton cable that this utility model provides also comprises the first bundle yarn 10 further.First pricks yarn 10 in strip, and between waterstop 5 and skeleton 4, first bundle yarn 10 is wound around along the radial direction of skeleton 4, first pricks yarn 10 can be fixed in skeleton grooves by fibre ribbon 2, prevent before the vertical bag of waterstop 5, when this skeleton cable core (part within waterstop 5) is wound around on traction wheel, fibre ribbon 2 jumps out skeleton grooves.In addition, in work progress, when taking out fibre ribbon 2 needed for the part in skeleton grooves, the first bundle yarn 10 can ensure that the good boundling of other fibre ribbons 2 in skeleton grooves is loose in skeleton grooves and take off.First pricks yarn 10 can be wrapped on skeleton 4 before filling material 9 is filled, and not only facilitates ointment filling material 9 more easily to fill, ointment filling material 9 can also be made better to concentrate in skeleton grooves, better to protect fibre ribbon 2.
In addition, because in the main laying tension by skeleton 4 in cabling process long more than skeleton cable, production run, tension force, the laying tension of fibre ribbon 2 and the takeup tension of skeleton cable core acted on skeleton 4 ensures, first pricks yarn 10 is bundled on skeleton 4, can not to the effect of the long generation power of the fibre ribbon more than 2 of skeleton grooves inside, namely fibre ribbon more than 2 can not be affected long, but first pricks yarn 10 can be good at concentrated light fibre ribbons 2, make fibre ribbon 2 can be movable in skeleton grooves, and fibre ribbon 2 can not be caused to escape from skeleton grooves, cause the situation that fibre ribbon 2 index is bad.
This skeleton cable can further include metal tape 7 and pricks yarn 11 for second of fixing waterstop 5.Second pricks yarn 11 between waterstop 5 and metal tape 7, second bundle yarn 11 is wound around along the radial direction of skeleton 4, second pricks yarn 11 for bundling the waterstop 5 of fixing vertical bag, and prevent in the process be wound around in the production run of skeleton cable or on dish tool, waterstop 5 relaxes.
Here it should be noted that; in order to make the first bundle yarn 10 better protection fibre ribbon 5; 2 or 3 first can be wound around prick yarn 10 on skeleton 4; equally; second quantity of pricking yarn 11 also can be 2 or 3; better to protect waterstop 5, avoid waterstop 5 to get loose, be more conducive to the fire resistance characteristic improving this skeleton cable.In addition, the metal tape 7 of this skeleton cable can be specially plastic-coated metal tape 7, and namely surface is coated with the metal tape of plastics, and plastic-coated metal tape 7 has good mechanical property, and good toughness, withstand voltage and impact resistance good, better can protect this skeleton cable.
Concrete, this skeleton cable can be 144 core filled type skeleton cables, namely skeleton 4 has 6 skeleton grooves, and import 46 core optic fibre belt optics in each skeleton grooves, certainly, this skeleton cable also can be the skeleton cable of other core numbers.
Above skeleton 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.
