Abstract
The utility model discloses a packing for cable becomes sectorial packing body including the cross -section, and the surface of packing body is equipped with arch and the recess that distributes alternately, and protruding cross sectional shape be 34 circular, and the groove cross -section shape be 34 circular, and packing body center is equipped with optical fiber hole, and the central optical fiber hole both sides of packing body are equipped with a through -hole respectively, are equipped with the tensile area on the packing body of optical fiber hole inboard. This neotype beneficial effect does: 1, arch that distributes alternately and recess that the outside set up have certain elasticity and strike the space, can protect inside cable, improve the impact resistance of cable, 2, optical fiber unit can effectually utilize the cable inner space in arranging the packing in, saves the external inoxidizing coating of optical fiber unit, 3, being equipped with dry powder in the through -hole, can breaking when the optical cable takes place conflagration or other calamities when catching fire, the flame that in time goes out avoids bigger calamity to take place, 4, fill the area and be equipped with the tensile area, can improve the tensile strength of cable.
Description
Technical field
The utility model relates to electricapparatus and equipment is manufactured field, relates in particular to a kind of cable optic fibre compound with fillingBar.
Background technology
In cable production process, for ensureing the rounding property of cable, avoid phase mutual friction between heart yearn simultaneously, need onlineBetween core, add packing material, if do not added packing material, for the cable of some irregularity, in the time extruding oversheath, sheathCan be because not rounding of stranding, there is gap and cause uneven thickness, concentricity is defective, and What is more due to construction of cable shakiness,Inner support is not got up, and causes unbalance stress, under external force impact, may damage core.
In addition, intelligent grid cable is registered one's residence as a new network system, comprises power network, telecommunications network, internet etc.Many net unification transmission cables, can carry out management such as user's remote meter reading and time sharing electrical energymeasuring simultaneously, this type of construction of cable,Mainly formed by fiber unit and metallic conductor electric power cable core. This type of composite cable manufacturing process is for to increase outward at multifiber at presentAdd metal or nonmetal reinforcement sheath becomes the fiber unit with shielding layer structure, then by this fiber unit and metallic conductor cable coreTwisted synthesizing cable together, adds non-hygroscopic gasket for packing between each cable core. This processing mode is because needs are by fiber unit and goldBelong to conductor cable core stranding together, and the mechanical strength of metallic conductor cable core is much larger than fiber unit, so just easily causes damage lightFine unit. This just requires to increase fiber unit and strengthens sheath thickness outward, to improve the mechanical strength of fiber unit. But carry like thisHigh weight and the cost of cable, and laid down cost.
Summary of the invention
The purpose of this utility model is that a kind of filling strip of power cable will be provided.
For achieving the above object, the utility model is implemented according to following technical scheme: a kind of filling strip of power cable, bagDraw together cross section and become fan-shaped packing body, the surface of described packing body is provided with the projection and the groove that distribute alternately, described inConvex sectional shape be 3/4 circle, described groove cross sectional shape is 3/4 circle, described packing body center is provided withOptic fibre hole, the optic fibre hole both sides at described packing body center are respectively equipped with a through hole, the filling out of described optic fibre hole inner sideFilling bar body is provided with the axially extended tension band of packing body.
Further, as a kind of preferred version, in described through hole, be filled with 1/3 dry powder.
Further, as a kind of preferred version, the 1.1-1.5 that the aperture of described optic fibre hole is fiber unit doubly.
Compared with prior art, the beneficial effects of the utility model are: the projection distributing alternately that 1, outside arranges and recessedGroove, has certain elasticity and impacts space, can protect inner cable, improves the impact resistance of cable; 2, fiber unitBe placed in packing, can effectively utilize space in cable, save the external overcoat of fiber unit; 3, in through hole, be provided with dryPowder can fracture time on fire in the time of optical cable breaking out of fire or other disasters, knocks out in time flare, avoids larger disasterOccur; 4, filling tape is provided with tension band, can improve the tensile strength of cable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described, in the signal of this utility modelProperty embodiment and explanation be used for explaining the utility model, but not as to restriction of the present utility model.
A kind of filling strip of power cable as shown in Figure 1, comprises that cross section becomes fan-shaped packing body 1, described packingThe surface of body 1 is provided with the projection 2 and the groove 3 that distribute alternately, and described projection 2 cross sectional shapes are 3/4 circle, described groove3 cross sectional shapes are 3/4 circle, and described packing body 1 center is provided with optic fibre hole 4, the light at described packing body 1 center4 both sides, fine hole are respectively equipped with a through hole 5, and the packing body 1 of described optic fibre hole 4 inner sides is provided with packing body 1Axially extended tension band 6. In through hole 5, be filled with 1/3 dry powder. The aperture of optic fibre hole 4 is 1.1-1.5 times of fiber unit.
The utlity model has following effect: the projection distributing alternately 2 and groove 3 that 1, outside arranges, have certainElasticity and impact space, can protect inner cable, improves the impact resistance of cable; 2, fiber unit is placed in packing,Can effectively utilize space in cable, save the external overcoat of fiber unit; 3, in through hole 5, be provided with dry powder, can be at optical cableWhen breaking out of fire or other disasters, fracture time on fire, knock out in time flare, avoid larger disaster to occur; 4, filling tapeBe provided with tension band 6, can improve the tensile strength of cable.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, every according to skill of the present utility modelThe technology distortion that art scheme is made, within all falling into protection domain of the present utility model.
