The technical solution of the utility model is：
A kind of armouring rodent-resistant cable, it is covered by external sheath layer, inner restrictive coating, protective layer, protection against rodents layer, center reinforcemen and pine
Pipe is formed；It is characterized in that：Protective layer, inner restrictive coating and protection against rodents layer are disposed with inside external sheath layer；The center of protection against rodents layer
It is provided with center reinforcemen；Loose tube is evenly equipped between protection against rodents layer and center reinforcemen.
The protective layer is formed by common chromium plating composite steel band longitudinal wrap, and the interface section of common chromium plating composite steel band is mutual
It overlaps.
The protection against rodents layer is formed by stainless steel band longitudinal wrap, and the interface section of stainless steel band mutually overlaps.
The center reinforcemen is made of reinforcement steel wire or is made of the reinforcement steel wire of package plastics enhancement layer；
The Loose tube is made of ferrule and optical fiber；Multiple optical fiber are installed in regular shape in ferrule；Respectively
Optical fiber is with being filled with special protection fiber paste in ferrule inner space.
Waterproofing type ointment is filled between the Loose tube and protective layer.
The external sheath layer, inner restrictive coating are made respectively of protection against rodents type PE plastics, and external sheath layer and protective layer it
Between be wound with layer of glass yarn.
The utility model has the advantage of：
The armouring rodent-resistant cable is simple in structure, ingenious in design, employs PE layers of armour protective layer and protection against rodents and glass fibre
Yarn layer carries out the mode of multilayer protection, avoids mouse and bites optical cable broken, influences the generation of communication issue.And armouring stainless steel band
For protection against rodents layer in inner ring position, diameter is smaller, and during using stainless steel band longitudinal wrap, required material is few, and easy longitudinal tubing.And then
It solves the problems, such as that stainless steel band difficult forming, easy torsion crack and manufacture that existing rodent-resistant cable has are of high cost, meets
The needs that people use.

Specific embodiment
The armouring rodent-resistant cable is by external sheath layer 1, inner restrictive coating 2, external protection coating 3, protection against rodents layer 4, center reinforcemen and pine
Casing is formed.External sheath layer 1 and inner restrictive coating 2 are made respectively of protection against rodents type PE plastics.
Protective layer 3, inner restrictive coating 2 and protection against rodents layer 4 are disposed with inside oversheath protection against rodents PE layers 1.Protective layer 3 is by common
Chromium plating composite steel band armour protective layer longitudinal wrap forms, and the interface section of common chromium plating composite steel band armour protective layer is mutually overlapped on
Together.The purpose of setting protective layer 2 is：First, using the shielding properties of metal tape, enhance its communication efficiency；Second is that enhance it
Damaged by rats barrier propterty avoids after restrictive coating 1 destroyed, damages the generation of Loose tube problem.
Protection against rodents layer 4 is formed by stainless steel band longitudinal wrap, and the interface section of stainless steel band mutually overlaps.Protection against rodents layer is set
4 purpose is：The characteristics of being not easy oxidation corrosion using stainless steel band and mouse bite the characteristics of not bad, it is made to have protection against rodents work(
Can, it avoids after mouse stings bad protection against rodents layer 4, gnaws the generation of disconnected 8 problem of optical fiber.
The purpose that protection against rodents layer 4 is placed in internal layer is：When protection against rodents layer 4 is in internal layer position, diameter is smaller, using stainless steel
During band longitudinal wrap, required material is few, and easy longitudinal tubing, reduces production difficulty, has saved production cost, and protection against rodents layer 4
Under the constraint of 1 protective layer 3 of external sheath layer and inner restrictive coating 2, stainless steel band is not easy to crack, and then avoids existing rodent-resistant cable
The problem of easy torsion crack having.
Protection against rodents layer 4 is provided centrally with center reinforcemen；Center reinforcemen is made of reinforcement steel wire 5 or is added by package plastics
The reinforcement steel wire 5 of strong layer 6 is formed.The purpose of setting center reinforcemen is：Enhance the intensity of optical cable；It is wrapped when on reinforcement steel wire 5
When wrapping up in plastics enhancement layer 6, which so just can guarantee that the optical cable can be bent in disk for certain hardness and tensile strength
Shape is convenient for conveying；It is can guarantee again during air-blown installation, be unlikely to the problem of the swinging that shake.
Loose tube is evenly equipped between protection against rodents layer 4 and center reinforcemen.Loose tube is made of ferrule 7 and optical fiber 8；Optical fiber
Multiple optical fiber 8 are installed in regular shape in casing 7.
Each optical fiber 8 is with being filled with special protection fiber paste 11 in 7 inner space of ferrule.Between Loose tube and protective layer 3
Filled with waterproofing type ointment 9.The purpose of setting waterproofing type ointment 9 is：Moisture in air and moisture can be prevented to optical cable
It corrodes, the influence of the mechanical forces such as vibrations, impact and the bending of outer bound pair optical cable can also be alleviated.Special protection fiber paste 11 is set
Purpose is：Optical fiber 8 can be made to be in free low-stress state inside ferrule 7.
As a kind of improvement of the utility model, layer of glass yarn is wound between external sheath layer 1 and protective layer 3
10.The purpose of setting glass fiber yarn 10 is：The light and hard characteristic having using glass fiber yarn 10 strengthens oversheath
Layer 1 mechanical strength, while make mouse bite glass fiber yarn 10 when, make its generate tingling sensation, and then alleviate mouse and its
The destruction that its animal continuously bites to optical cable；And then reach protection optical cable, the effect that defence mouse suffers from.
The armouring rodent-resistant cable is simple in structure, ingenious in design, employs the mode of protective layer and the protection of protection against rodents layer multi-layer, keeps away
Exempt from mouse and bitten optical cable broken, influence the generation of communication issue.It solves difficult forming, easily torsion that existing rodent-resistant cable has to open
It splits and manufactures the problem of of high cost, meet the needs that people use.
