Embodiment
For the ease of the understanding of those skilled in the art, the utility model is made with reference to embodiment and accompanying drawing further
Explanation, the content that embodiment refers to not to restriction of the present utility model.
Refer to Fig. 1 and Fig. 2, a kind of multifiber cable of the present utility model, including be arranged side by side multiple optical fiber, be set in
The metal spiral armour pipe 1 of multiple outer fibers, the aramid fiber pipe 2 for being set in the outside of metal spiral armour pipe 1 and it is set in aramid fiber
The protecting tube 3 in the outside of fibre pipe 2, in the present embodiment, metal spiral armour pipe 1, aramid fiber pipe 2 and protecting tube 3 substantially in
Empty strip, each optical fiber include fibre core 4 and are set in the just knowledge set 5 in the outside of fibre core 4, the just knowledge set 5 of multiple optical fiber
Color it is different, for example, the just knowledge of one of optical fiber set 5 is arranged into green, the just knowledge set 5 of another optical fiber is arranged to
Yellow etc..In the present embodiment, helicla flute 6 is provided with the metal spiral armour pipe 1,6 blind slots of helicla flute, i.e. helicla flute 6 are not
Through the wall thickness of metal spiral armour pipe, length direction extension of the helicla flute 6 along metal spiral armour pipe 1 forms, and helicla flute 6 is from metal
The outer surface of spiral armour pipe 1 is integrally recessed to be formed.
The utility model multifiber cable is easy to quickly know by the way that the set 5 of just knowing of each optical fiber is arranged into different colors
Not each optical fiber is simultaneously attached, and lifts the installation effectiveness of optical cable；By being arranged metal spiral armour pipe 1 in outer fiber, utilize
Metal spiral armour pipe 1 strengthens the intensity of optical cable, it is ensured that optical cable has the ability for resisting high-strength side pressure, by metal spiral armour pipe 1
Upper setting helicla flute 6, ensures that optical cable has less bending radius, is easy to optical cable to be wound when in use.
The aramid fiber pipe 2 is used to protect optical fiber and metal spiral armour pipe 1, and the material of aramid fiber pipe 2 is former
It is named as " PPTA ", the recurring unit of chemical formula is connected on benzene for-[- CO-C6H4-CONH-C6H4-NH-]-
Amide group on ring is aligning structure, is commonly called as fire proofing firbre, have a good resistance to acids and bases, and can organic solvent-resistant invade
Erosion, meet fire and produced without molten drop, do not produce toxic gas.
Just latex 7 is equiped between the knowledge set 5 and metal spiral armour pipe 1, latex 7, which is filled in, just knows set 5 and metal spiral shell
Revolve in the gap between armour pipe 1, prevent optical fiber from directly being contacted with metal spiral armour pipe 1, utilize the flexible spy of latex 7 itself
Property enter row buffering to optical fiber, after the power in the external world is applied on optical cable, latex 7, which absorbs, is applied to power on optical cable, avoids outer
The power on boundary is acted directly on optical fiber, it is ensured that optical fiber will not fracture easily when optical cable is impacted by the power that the external world applies.
The protecting tube 3 is mixed by polyvinyl chloride and fluorescent material, is had waterproof by polyvinyl chloride optical cable, is prevented
Oily function, fluorescent material are also known as luminescent powder, and the main component of fluorescent material is rare earth, belong to mineral-type materials, fluorescent material is by certainly
After the irradiations such as right light, daylight light or ultraviolet light, luminous energy is stored, after stopping light irradiation, then slowly with the side of fluorescence
Formula discharges, so at night or dark, remain to see it is luminous, by the way that fluorescent material is added in protecting tube 3 so that
Optical cable can light in the environment of night or dark, and convenient use person watches optical cable, prevents user at night or black
Colliding optical cable in dark environment causes optical fibre damage.Preferably, the mass percentage content of polyvinyl chloride is in protecting tube 3
90% or so, the mass percentage content of fluorescent material is 10% or so.
The metal spiral armour pipe 1 is made of magnetic conductive metal, in this way, when extraneous electromagnetic wave is transferred to metal spiral armour
After pipe 1, when extraneous electromagnetic wave forms electric field around metal spiral armour pipe 1, due to the short circuit effect of magnetic conductive metal, destroy
The formation of electric field, and then the signal for avoiding the inner fiber of Electromagnetic Interference metal spiral armour pipe 1 in the external world from being transmitted.Preferably, it is golden
Category spiral armour pipe 1 is made of dilval, and the mass percentage content of nickel is 30%~90%, utilizes the weak magnetic of dilval
Field permeability so that metal spiral armour pipe 1 has better anti-electromagnetic interference capability.
The multifiber cable also includes carbon fiber pipe 8, and carbon fiber pipe 8 is substantially in hollow strip, and carbon fiber pipe 8 is arranged
In the outside of metal spiral armour pipe 1, carbon fiber pipe 8 is clamped between metal spiral armour pipe 1 and aramid fiber pipe 2, carbon fiber tool
