Description
Technical field
The utility model is related to butterfly optical cable field, in particular to a kind of anti-biological closed type butterfly leading in cable.
Background technology
With the Efforts To Develop of FTTH, broadband China strategy is in full swing.China city and rural area largely use butterfly
Leading in cable.
Butterfly optical cable is setting up intelligent Building, digital cells, campus as a kind of traditional user's access optical cable at present
Extremely important effect is played in the networks such as net, LAN.According to application environment and laid condition flexible design, collection is indoor soft
The characteristics of optical cable and self-support cable, coordinates indoor junction box, quick connector and fibre faceplate, so that it may connect fiber to family
And to desktop, engineering construction efficiency is not only improved, also saves operating expenses.
Traditional butterfly leading in cable is in the intensive city of trees, suburb and rural area, and inevitable optical cable can be rolled up in construction
Bent, torsion or unbalanced stress, when there is such case, the place that traditional butterfly leading in cable stress is most concentrated is precisely both sides
Corresponding tie point at fluting, and tie point face optical fiber, and protect the measure of optical fiber quite weak, except there is one layer of very thin shield
Layer is outer, and no other materials is very poor to the protection of optical fiber.
And the design slotted was to take out optical fiber to be conducive to divest optical cable originally, but was easy to stress in the construction process
And be voluntarily torn, it easily seeps water, causes optical fiber hydrogen loss, increase fiber attenuation coefficient, reduce optical fiber service life.
The more region of some insects simultaneously, can be by insect pair after construction because the protection at optical fibre in optical cable is weaker
The destruction of optical cable.
Because insects is convenient for stop at fluting and is hidden, so insects misses potter oviposition, insect at optical cable fluting
By the black oversheath of butterfly leading in cable as withered trunk, in the position of optical cable fluting, pass through the thorn among tube for laying eggs
It rubs repeatedly in coarse cable surface, cable surface is made to wear to form certain aperture under rubbing action, then start 180 °
Hole by jagged tube for laying eggs is worn and expanded by reciprocating spin friction, until the size and depth in hole are suitble to oviposition,
Because fiber optic protection is weak at the fluting of traditional butterfly optical cable, the oversheath of optical cable is easily pierced through, optical fiber is injured, influences normally to believe
Message communication.
By long-term production and practice, traditional butterfly leading in cable is unsuitable in many practical applications
It promotes the use of, it is necessary to the leading in cable for meeting more structural requirements and performance requirement is developed, to improve user's leading in cable
Reliability and applicability.
Do not have anti-insect bite covered wire cable also on the market at present, common covered wire cable butterfly optical cable tear line position sheath compared with
It is thin, under being used for a long time after laying, insect bite, oviposition are be easy to cause, larva grows in restrictive coating, causes insect pest or even cause light
Cable breaks fine phenomenon；Covered wire cable is easily intake in joint leads to fibre loss bad phenomenon.

Embodiment.
Present embodiments provide a kind of anti-biological closed type butterfly leading in cable.
Referring to Fig. 1, this anti-biological closed type butterfly leading in cable includes optical cable ontology 100, optical cable ontology 100 is cut
Face is circle, and optical cable ontology 100 is included positioned at external restrictive coating 110, and restrictive coating 110 is included about 100 center of optical cable ontology
Symmetrical first restrictive coating, 110 and second restrictive coating 110 forms two between first restrictive coating 110 and the second restrictive coating 110 and opens
Slot 120 is provided with stripping item 130 in fluting 120, and the side of stripping item 130 connects the first restrictive coating 110 and the second restrictive coating 110.Light
Cable ontology 100 further includes the reinforcer protective layer 140 inside restrictive coating 110, the part and shield of reinforcer protective layer 140
The inner wall connection of jacket layer 110, has gap between reinforcer protective layer 140 and stripping item 130.Reinforcer protective layer 140 is towards stripping
The side of item 130 forms V-structure, and the section of stripping item 130 is fan annular.Reinforcer protective layer 140 is about optical cable ontology 100
Symmetrical structure, reinforcer protective layer 140 are internally provided with two reinforcements 141.It is additionally provided with inside reinforcer protective layer 140
Optical fiber 142, optical fiber 142 are located at the center of optical cable ontology 100.It shells item 130, the first restrictive coating 110, the second restrictive coating 110 and adds
Strong part protective layer 140 is an integral structure.Optical cable ontology 100 is process with extrusion process, and restrictive coating 110 is high flame resistance, low smoke
Halogen-free polyolefin material.The outside of stripping item 130 has the coating that the outside with restrictive coating 110 distinguishes.The side of optical cable ontology 100
Portion is connected with messenger wire.
Stripping item 130, the first restrictive coating 110, the second restrictive coating 110 and reinforcer protective layer 140 are an integral structure, and are used
Extrusion process is process, and entire optical cable ontology 100 has higher intensity, has the characteristics such as good water-impervious, anti-insect bite.
