Background technology
Flat type optical cable compared to circular optical cable for, the jacket thickness of optical cable is relatively thin, can not only save optical cable cost,
And due to the thinner thickness of optical cable, the good temp characteristic of optical cable is suitable for optical cable and introduces use.But since optical fiber is in environment temperature
Spend it is higher in the case of, performance can be affected, thus optical cable be not suitable for use at high temperature, affect flat type optical cable use model
It encloses.Flat type optical cable is the structure of flat simultaneously, is easy to be impacted by upper and lower lateral pressure, is impacted to optical fiber, shorten light
Fine service life.Therefore provide that a kind of high temperature resistant, use scope be wide, measuring body flat type optical cable is to be solved by this invention asks
Topic.
Invention content
The present invention overcomes the deficiencies in the prior art, provide that a kind of high temperature resistant, use scope be wide, measuring body flat type optical cable.
In order to achieve the above objectives, the technical solution adopted by the present invention is：A kind of heat safe flat type optical cable is provided, it is special
Sign is：A kind of heat safe flat type optical cable, it is characterised in that：Including sheath, optical fiber, support element, reinforcer；The optical fiber is set
It sets in the middle part of the sheath, the support element, which is arranged between the both sides of optical fiber, the optical fiber and support element, is arranged several reinforcements
Part；Carbamide protective layer is set on the outside of the sheath.
As a preferred embodiment, the support element radius is more than the fiber radius.
As a kind of more preferable scheme, the support element is phosphatization high-carbon steel wire reinforcement.
As a kind of more preferable scheme, the reinforcer is that resin is reinforced at glass fibre center.
As a kind of more preferable scheme, cavity is respectively set in the optical fiber over and under.
As a preferred embodiment, the sheath upper and lower surface is each provided with groove of the indent direction towards optical fiber.
As a kind of more preferable scheme, the groove is V-shape groove.
As a kind of more preferable scheme, the V-shape groove apex angle is 120 °.
As a preferred embodiment, wearing layer is set on the outside of the carbamide protective layer.
As a kind of more preferable scheme, the wearing layer is layer of polyurethane.
The advantageous effects of the present invention essentially consist in：Provide that a kind of high temperature resistant, use scope be wide, measuring body flat type light
Cable.Carbamide protective layer is arranged in the present invention outside cable jacket.Carbamide has very strong hydrophilicity and water absorbing capacity.It exists can be with
The humidity for increasing flat type optical cable ambient enviroment, reduces the temperature of subenvironment around optical cable, to improve the high temperature resistant of optical cable
Property, extend the use scope of optical cable.Carbamide protective layer is of low cost simultaneously, is conducive to save production cost.This hair simultaneously
Bright to be more than support element in optical fiber both sides setting radius, when optical cable bears foreign impacts, support element can bear most effect
Power, to preferably protect optical fiber.Cavity is respectively set over and under, when optical cable is by upper and lower impact, cavity can be with
Play the role of buffering, pressure will not be applied directly to optical fiber, to protect optical fiber.It is also set up between optical fiber and support element
Reinforcer, reinforcer are distributed in optical fiber surrounding, play auxiliary protection function, improve the protection to optical fiber.Pass through triple protection
Collective effect improves the impact resistance of optical cable, extends the service life of optical fiber.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structural schematic diagram of the preferred embodiment of the present invention.
In figure：1 it is sheath, 2 be optical fiber, 3 be support element, 4 be reinforcer, 5 be carbamide protective layer, 6 is wearing layer, 7
For the groove that cavity, 8 are jacket surface.
Specific implementation mode
Presently in connection with drawings and examples, the present invention is described in further detail, these attached drawings are simplified signal
Figure, the basic structure of the invention will be illustrated schematically only, therefore it only shows the composition relevant to the invention.
As shown in Figure 1, a kind of heat safe flat type optical cable, including sheath 1, optical fiber 2, support element 3, reinforcer 4.Optical fiber 2
At 1 middle part of sheath, support element 3, which is arranged between the both sides of optical fiber, optical fiber 2 and support element 3, is arranged several reinforcers 4 for setting.
Carbamide protective layer 5 is arranged in flat type optical cable outer surface, and carbamide has very strong hydrophilicity and water absorbing capacity.Carbamide
The heat-resisting quantity of optical cable is improved, is extended to reduce the temperature of subenvironment around optical cable in the presence of the humidity for increasing environment
The use scope of optical cable.Carbamide protective layer simultaneously is of low cost, is conducive to save production cost.In addition it is protected in carbamide
5 outside of layer also sets up wearing layer 6, and wearing layer 6 is layer of polyurethane.Polyurethane has preferable wearability, and of low cost, source
Extensively, while there is preferable flexibility, it can be with effective protection flat type optical cable.
Support element 3 inside cable jacket 1, is arranged the radius that its radius is more than optical fiber 2, and material increases for phosphatization high-carbon steel wire
Strong part.Reinforcer 4 is arranged 4 and is distributed in 2 surrounding of optical fiber, and material is that resin is reinforced at glass fibre center.2 top of optical fiber simultaneously
And it is respectively arranged below the cavity 7 of the length direction extension along optical cable.It is carried by the setting of support element 3, reinforcer 4, cavity 7
The high resistance to pressure of optical cable.Due to support element 3 radius ratio optical fiber 2 it is big, so when optical cable bears foreign impacts, support element
