Abstract
The invention discloses a tightly-packaged fiber and a method for manufacturing the tightly-packaged fiber. The tightly-packaged fiber comprises a fiber body, a resin coating and a tight packaging material. The resin coating is attached to the fiber body, the fiber body is coated with the resin coating, the tight packaging material is attached to the resin coating, and the resin coating is coated with the tight packaging material. The method for manufacturing the tightly-packaged fiber comprises the following steps that the fiber body is coated with the resin coating, and the resin coating is coated with the tight packaging material so as to ensure that a compressing and contracting process is conducted on the tight packaging material. According to the technical scheme of the tightly-packaged fiber, a traditional tightly-packaged fiber structure is simplified to be a three-layer structure, a tearing opening and a breaking layer are arranged on the surface and the interior of the three-layer structure respectively, and therefore the fiber can be conveniently stripped. Furthermore, according to the manufacturing method, production efficiency can be improved, and cost and technical requirements for production personnel can be reduced.
Description
Technical field
The present invention relates to light belt unit of a kind of user's house wiring optical fiber cable and preparation method thereof, more particularly, relate to a kind of tightly packaged fiber and preparation method thereof.
Background technology
In the situation that optical cable technology is popularized at present, there is the optical cable of all kinds and signal on the market, but no matter adopts which kind of optical cable, its inner optical fiber is the core of whole optical cable quality.Can say that the performances and parameters of optical fiber has directly determined the quality of optical cable.
Tightly packaged fiber uses in most of optical cables of determining usually, only has the optical cable of a few types not adopt tightly packaged fiber.Therefore, the quality of tightly packaged fiber can determine the quality of numerous optical cables.Yet the problem that common tightly packaged fiber faces usually is that optical fiber is difficult for peeling off, and causes properties of product to be very restricted.On the other hand, the making of existing optical fiber structure is comparatively complicated, so cost is high, production efficiency is low, and also higher to producers' technical requirement.
Summary of the invention
Purpose of the present invention aims to provide a kind of tightly packaged fiber and preparation method thereof, solves the various deficiencies that exist in the prior art.
According to the present invention, a kind of tightly packaged fiber is provided, comprise optical fiber, resinous coat and hard-pressed bale material.Resinous coat is close to and clad optical fiber, and the hard-pressed bale material is close to and resin-coated coating.
According to one embodiment of the invention, the cross section of resinous coat and hard-pressed bale material all is annular, and resinous coat is positioned at nexine, and the hard-pressed bale material is positioned at skin.
According to one embodiment of the invention, the hard-pressed bale material surface is provided with radially tearing port.
According to one embodiment of the invention, resinous coat is provided with a minute tomography vertically.
According to a further aspect in the invention, provide a kind of method of tightly packaged fiber, may further comprise the steps: in optical fiber outside surface coated with resins coating, at resinous coat outer cladding hard-pressed bale material, the hard-pressed bale material is compressed shrinking process.
According to one embodiment of the invention, offer radially tearing port at the hard-pressed bale material surface.
According to one embodiment of the invention, at resinous coat a minute tomography is set vertically.
Having adopted technical scheme of the present invention, is three-decker with traditional tightly packaged fiber designs simplification, and tearing port is set respectively and divides a tomography on its surface and inside, can be so that the peeling off of optical fiber.On the other hand, the present invention also provides the method for making of this tightly packaged fiber, can enhance productivity, and reduces cost and minimizing for producers' technical requirement.
Description of drawings
In the present invention, identical Reference numeral represents identical feature all the time, wherein:
Fig. 1 is the cross-sectional view of tightly packaged fiber of the present invention.
Fig. 2 is the process flow diagram of tightly packaged fiber method for making of the present invention.
Embodiment
Further specify technical scheme of the present invention below in conjunction with drawings and Examples.
As shown in Figure 1, tightly packaged fiber 10 of the present invention comprises optical fiber 11, resinous coat 12, hard-pressed bale material 13, tearing port 14 and minute tomography 15.Wherein, the cross section of resinous coat 12 and hard-pressed bale material 13 all is annular, and resinous coat 12 is positioned at nexine, and hard-pressed bale material 13 is positioned at skin, and namely resinous coat 12 is close to and clad optical fiber 11, and hard-pressed bale material 13 is close to and resin-coated coating 12.
As a kind of preferred implementation of the present invention, the cross sectional shape of resinous coat 12 and hard-pressed bale material 13 is not the formation limitation of the present invention only with explaining here.The optical fiber cross section of other common shapes, for example rectangle or polygon can be realized purpose of the present invention equally.
On the surface of hard-pressed bale material, offer tearing port 14, the direction of tearing of tearing port 14 is the radial direction along tightly packaged fiber 10, namely tearing port 14 can be torn hard-pressed bale material 13, exposes inner resinous coat 12.
Interphase place at resinous coat 12 and hard-pressed bale material 13 is provided with minute tomography 15, and the direction of minute tomography 15 is the axial direction along tightly packaged fiber 10.When tearing tightly packaged fiber 10; tearing port 14 tears hard-pressed bale material 13 to dividing a tomography 15 to go out from the surface; then divide tomography 15 just can disconnect relatively easily; can make like this operating personnel that certain feel is arranged; when tearing to minute tomography 15; divide tomography 15 can play the effect of prompting, make operating personnel not continue down to tear, thus resinous coat 12 and the optical fiber 11 of protection hard-pressed bale material 13 inside.
As shown in Figure 2, the method for making of tightly packaged fiber 10 of the present invention such as following steps:
Step 21: optical fiber outside surface coated with resins coating.
Step 22: a minute tomography is set vertically at resinous coat.
Step 23: at resinous coat outer cladding hard-pressed bale material.
Step 24: offer radially tearing port at the hard-pressed bale material surface.
Step 25: the hard-pressed bale material is compressed shrinking process.
The present invention is three-decker with traditional tightly packaged fiber designs simplification, and tearing port is set respectively and divides a tomography on its surface and inside, can be so that the peeling off of optical fiber.On the other hand, step 21～25 also provide the method for making of tightly packaged fiber of the present invention, can enhance productivity, and reduce cost and minimizing for producers' technical requirement.Specifically, product of the present invention is once produced, the operation simple and fast, therefore can make production efficient improve 25%, the post shrinkage of hard-pressed bale layer is little, and be no longer high as common hard-pressed bale to producers' functipnal capability requirement, and can improve the environmental performance of tightly packaged fiber.
Those of ordinary skill in the art will be appreciated that above instructions only is one or more embodiments among the numerous embodiment of the present invention, and is not to use limitation of the invention.Any for the above embodiment equalization variation, modification and be equal to the technical schemes such as alternative, as long as connotation scope according to the invention, all will drop in the scope that claims of the present invention protect.
