Description
Technical field
The invention belongs to optical cable technology field, a kind of butterfly leading in cable is particularly related to.
Background technology
Butterfly optical cable is a kind of novel user access optical cable, different with laid condition according to application environment, rationally designs light
Cable structure and every technical parameter, the characteristics of having gathered indoor flexible optical cable and self-support cable, coordinate import using special equipment
Precision die is produced.The reinforcer of current butterfly cable employs two kinds of metal reinforcement and non-metal reinforcement member, and metal adds
Strong part can be conductive, but intensity is high, and non-metal reinforcement member is non-conductive, but expensive and low intensity.
The content of the invention
In order to solve the above problems, the invention provides a kind of high and moderate butterfly leading in cable of intensity.
In order to achieve the above object, the present invention is achieved by the following technical solutions：
The present invention is a kind of butterfly leading in cable, including optical fiber, the left stiffener assembly for being arranged on the optical fiber left and right sides, right reinforcement group
Part and restrictive coating, left stiffener assembly include left metallic strength member, and several nylon are provided with the outside of left metallic strength member and are strengthened
Rod, is provided with aramid fiber reinforcing core between two adjacent nylon stirrups, and right stiffener assembly includes right nonmetallic reinforcement
Core, fiberglass-reinforced plastic lever is set in the outside of right nonmetallic strengthening core, and water blocking tape layer is set in the outside of restrictive coating,
The outside of water blocking tape layer sets armouring aluminium strip layer, and outer protective polyethylene jacket layer is set in the outside of armouring aluminium strip layer.
Further improvement of the present invention is：Set fluted on sheath, gasket for packing is provided with each groove.
Further improvement of the present invention is：Used between left metallic strength member, nylon stirrup and aramid fiber reinforcing core
Cable cream is filled.
Further improvement of the present invention is：Using blocking water between right nonmetallic strengthening core and fiberglass-reinforced plastic lever
Ointment is filled.
Further improvement of the present invention is：The diameter of fiberglass-reinforced plastic lever differs.
Further improvement of the present invention is：Left metallic strength member is steel wire strengthening core.
The beneficial effects of the invention are as follows：Present invention employs metal reinforcement and non-metal reinforcement member as strengthening core, no
Only there is intensity and cost is low, and have nylon and aramid fiber reinforcement material on the outside of each metal reinforcement, improve
The intensity of optical cable, the fiberglass-reinforced plastic lever in the outside of nonmetallic strengthening core can also improve cable strength, and optical cable
Armor and water blocking layer are added on the outside of sheath, the water resistance and anti-wear performance of optical cable is improved.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
In order to deepen the understanding of the present invention, the present invention is done below in conjunction with drawings and examples and further retouched in detail
State, the embodiment is only used for explaining the present invention, protection scope of the present invention is not constituted and limited.
As shown in figure 1, the present invention is a kind of butterfly leading in cable, including optical fiber 1, it is arranged on the left and right sides of optical fiber 1
Left stiffener assembly, right stiffener assembly and restrictive coating 3, the left stiffener assembly include left metallic strength member 2, in the left metal
The outside of strengthening core 2 is provided with several nylon stirrups 4, it is preferred that nylon stirrup 4 is four, in two adjacent nylon
Aramid fiber reinforcing core 5 is provided between stirrup 4, aramid fiber reinforcing core 5 is four, also, the diameter of nylon stirrup 4
More than the diameter of aramid fiber reinforcing core 5, cost is reduced, the right stiffener assembly includes right nonmetallic strengthening core 6, on the right side
Nonmetallic strengthening core 6）Outside set fiberglass-reinforced plastic lever 7, the restrictive coating 3 outside set water blocking tape layer 9,
Armouring aluminium strip layer 10 is set in the outside of the water blocking tape layer 9, outer protective polyethylene is set in the outside of armouring aluminium strip layer 10
Jacket layer 11, sets fluted on the sheath 3, and gasket for packing 8 is provided with each groove, improves the intensity of optical cable,
Filled between the left metallic strength member 2, nylon stirrup 4 and the aramid fiber reinforcing core 5 with cable cream, the right side is nonmetallic
Filled between strengthening core 6 and the fiberglass-reinforced plastic lever 7 using greasy for preventing water, the fiberglass-reinforced plastic lever 7
Diameter differ, the left metallic strength member 2 be steel wire strengthening core.
Present invention employs metal reinforcement and non-metal reinforcement member as strengthening core, not only with intensity but also cost
It is low, and have nylon and aramid fiber reinforcement material on the outside of each metal reinforcement, the intensity of optical cable is improved, it is nonmetallic to add
The fiberglass-reinforced plastic lever in the outside of strong core, which can also be improved, adds armouring on the outside of cable strength, and the sheath of optical cable
Layer and water blocking layer, improve the water resistance and anti-wear performance of optical cable.
