Description
Technical field
The utility model relates to the technical field of optical cable, is specially a kind of reinforced outdoor butterfly optical cable.
Background technology
Because the diameter of butterfly optical cable is less, its tensile strength is poor, for avoiding the damage of optical cable, butterfly optical cable is usual and stiffener is simultaneously shaping, improve the tensile strength of optical cable, particularly outdoor butterfly optical cable, see Fig. 1, outdoor butterfly optical cable comprises the stiffener 2-1 of optical fiber 1 and optical fiber both sides, 2-2, the side of stiffener is provided with reinforcement 3, optical fiber, one-body molded by protective cover material 4 outside the stiffener of optical fiber both sides and reinforcement, with the overall tensile strength of the outer butterfly optical cable of enhanced room, in existing outdoor butterfly optical cable, because protective cover material and reinforcement adopt different materials, in the forming process of protective cover material and reinforcement, protective cover material and reinforcement can produce a joint portion, in the use procedure of outdoor butterfly optical cable, can rotate under external force and displacement between reinforcement and protective cover material, outdoor butterfly optical cable will produce distortion, have impact on the use of outdoor butterfly optical cable.
Summary of the invention
For the problems referred to above, the utility model provides a kind of reinforced outdoor butterfly optical cable, effectively can avoid reinforcement in protective cover material, produce rotation and displacement, thus effectively prevent the distortion of outdoor butterfly optical cable, ensure that the normal use of outdoor butterfly optical cable.
Its technical scheme is such, a kind of reinforced outdoor butterfly optical cable, it comprises the stiffener of optical fiber and optical fiber both sides, the side of stiffener be provided with reinforcement, one-body molded by protective cover material outside the described stiffener of described optical fiber, optical fiber both sides and described reinforcement, it is characterized in that: be connected by melt viscosity glue-line between described reinforcement with described protective cover material, form the adhesion of described reinforcement and described protective cover material.
It is further characterized in that: described reinforcement is steel wire.
In said structure of the present utility model, owing to being connected by melt viscosity glue-line between reinforcement with protective cover material, form the adhesion of reinforcement and protective cover material, reinforcement and protective cover material form stable connection by melt viscosity glue-line, can effectively avoid reinforcement in protective cover material, produce rotation and displacement, thus effectively prevent the distortion of outdoor butterfly optical cable, ensure that the normal use of outdoor butterfly optical cable.

Embodiment
See Fig. 2, a kind of reinforced outdoor butterfly optical cable, comprise stiffener 2-1,2-2 of optical fiber 1 and optical fiber 1 both sides, the side of the stiffener 2-1 of side is provided with reinforcement 3, one-body molded by protective cover material 4 outside stiffener 2-1,2-2 of optical fiber 1, optical fiber both sides and reinforcement 3, be connected by melt viscosity glue-line 5 between reinforcement 3 with protective cover material 4, form the adhesion of reinforcement 3 and protective cover material 4, reinforcement is steel wire or other Material reinforcement component.
Reinforced outdoor butterfly optical cable job operation, (1), reinforcement are by injecting glue mould, and hot melt adhesive injects injecting glue mould, forms melt viscosity glue-line outward at reinforcement; (2), the reinforcement of appearance coating hot-melt adhesive adhesive-layer enters in cable jacket extrusion molding mould and carries out extrusion moulding with optical fiber and stiffener.
See Fig. 3, hot melt adhesive forms melt viscosity glue-line 5 by injecting glue, reinforcement 3 is by injecting glue mould 6, hot melt adhesive is through 150-200 DEG C of heat fused, reinforcement penetrates injecting glue mould 6 with the speed of 40-60m/min, the hot melt adhesive of fusing injects injecting glue mould 6 with the pressure of 0.05-0.1MPa, at reinforcement 3 outer formation melt viscosity glue-line 5, reinforcement penetrates the speed of injecting glue mould is in fact determined by the speed of outdoor butterfly optical cable sheath extrusion moulding, the reinforcement described in the present embodiment penetrates with the speed of 40-60m/min the speed that injecting glue mould is also usual outdoor butterfly optical cable extrusion moulding.
See Fig. 3, the processing unit (plant) of reinforced outdoor butterfly optical cable, it comprises injecting glue mould 6, injecting glue mould 6 connects cable jacket extrusion molding mould 7, injecting glue mould 6 is separated by a distance with cable jacket extrusion molding mould 7, injecting glue mould 6 comprises pressure chamber and plug die (not shown in FIG.), and injecting glue mould 6 is independent of cable jacket extrusion molding mould 7 and synchronous working with cable jacket extrusion molding mould 7.
In order to increase the intensity of optical cable, reinforcement adopts steel wire usually, also can adopt the stiffener of other materials.
See Fig. 2, Fig. 3, Fig. 4 and Fig. 5, in order to ensure that all even thickness of melt viscosity glue-line is stablized, make surface glue amount evenly inexcessive, ensure hot melt adhesive non-contacting fiber, be provided with between injecting glue mould 6 and cable jacket extrusion molding mould 7 and keep off rubber moulding 8, gear rubber moulding 8 comprises gear rubber moulding body 9, optical fiber and stiffener through hole 10 and reinforcement through hole 11 is provided with in gear rubber moulding body 9, reinforcement through hole 11 is provided with the gear glue projection 12 corresponding with reinforcement, when passing gear rubber moulding 8 from the reinforcement 3 of the surface coverage hot melt adhesive of injecting glue mould 6 pull-out, the endoporus formed due to gear glue protruding 12 is comparatively accurate, gear glue projection 12 processes the melt viscosity glue-line 5 outside reinforcement 3, gear goes the excessive glue amount on reinforcement 3 external diameter, form the melt viscosity glue-line 5 that all even thickness is stable, simultaneously optical fiber and stiffener through hole 10 comparatively loose, optical fiber 1 and stiffener 2-1 are provided, the guiding of 2-2, optical fiber and stiffener through hole 10 and reinforcement through hole 11 are respectively by optical fiber, the reinforcement of stiffener and appearance coating hot-melt adhesive imports in cable jacket extrusion molding mould 7, keep at a certain distance away due to optical fiber and between stiffener through hole 10 and reinforcement through hole 11, effectively prevent optical fiber, the adhesion of stiffener and reinforcement surface heat melten gel, ensure hot melt adhesive non-contacting fiber.
below in conjunction with Fig. 3, the utility model is further described:
Heat the hot melt adhesive dissolved and inject injecting glue mould 6 by note cast gate 13, reinforcement 3 penetrates in injecting glue mould 6, the reinforcement of appearance coating hot-melt adhesive is by injecting glue mould 6, through gear rubber moulding 8, melt viscosity glue-line on reinforcement 3 surface is carried out uniform treatment, gear goes the excessive glue amount on reinforcement 3 external diameter, make surface glue amount evenly inexcessive and ensure that surface glue amount thickness is stablized, ensure hot melt adhesive non-contacting fiber, it is reinforced outdoor butterfly optical cable that reinforcement 3 after surface glue amount uniform treatment enters extrusion moulding while of carrying out with optical fiber and stiffener in cable jacket extrusion molding mould, the reinforced outdoor butterfly optical cable of extrusion moulding enters tank cooling, sizing, finally carry out lettering one-tenth dish, complete whole reinforced outdoor butterfly optical cable processing technology.
The extrusion moulding of the protective cover material 4 in the present embodiment, cable jacket extrusion molding mould 7 and outdoor butterfly optical cable is all the rapidoprint of the usual employing of outdoor butterfly optical cable in prior art, processing mold and job operation, so do not repeating in the description.
