Description
Technical field
What the pre-buried fiber type optical fiber quick coupler of the present invention related to is a kind of Passive Optical Components that is used for the on-the-spot fast rapid-result end of optical fiber cable.
Background technology
The broadband construction has become the aspect that rises to national strategy, and the scale that Fiber to the home builds is huge day by day.Broadband construction construction center of gravity is that the construction site is by in the outdoor reversal chamber, the end that lays into of optical cable is very important link, and for indoor narrow operating space, how reducing difficulty of construction is the emphasis problem of studying in the industry, adopt the expensive optical fiber splicer of tradition not only the cost of operational difficulty and input be huge, do not meet dispersiveness and instantaneity that the user opens.Optical fiber quick connector is to promote the necessary sharp weapon that Fiber to the home builds, and is regarded as implementing the necessity that large-scale F TTH builds, and has become the necessary means of effective reduction broadband access construction cost.Optical fiber quick connector need not Power Supplies Condition, at the scene can be with the direct Cheng Duan of optical fiber by simple artificial mechanism operation steps, realize opening fast, the flexible connection of optical fiber, save optical fiber pigtail and use input cost, and can realize the structure innovation and the upgrading of novel smooth wiring product.
How comprehensively observing the little curved situation of optical fiber in quick coupler is by the end of at present; need a problem solving in actual use, the life-span of this protection for optical fiber, product, the index reliability of field fabrication joint all are key factors.Further solve the lifting pulling force and become needs, because site operation environment particularly reconstruction of old area at present all needs optical cable is carried out repeatedly pulling and adjustment, therefore how promoting optical fiber quick connector pulling force index with more novel scientific methods also becomes the key index of judging the optical fiber quick connector characteristic.Pre-buried fiber type optical fiber quick coupler is because the joint end face has adopted the same factory level of fiber active linker to grind, therefore the return loss index is reliably guaranteed, but because this technical difficulty height, technique of alignment, clamping technology are its core key, how realizing importing fibre docks, how to realize importing fine safe clamping with the reliable of pre-buried fibre, it realizes complex process, and mode is also all different, has defectives such as success ratio is not high, operation inconvenience, the multiple kit of needs at present.Optical fiber quick connector repeatability has only been paid close attention to the repeat property of optical fiber cable holder and has been considered insufficient to pre-buried structure connection factor at present, have that efficient is not high, degradation defective under the index, the quick coupler of same more than one hundred million scales uses, and how to realize that the follow-up prolongation tieed up life of product is very crucial.
Summary of the invention
The present invention be directed to a kind of novel pre-buried fiber type optical fiber quick coupler of above-mentioned technical background exploitation, it is a kind of on-the-spot a kind of Passive Optical Components that optical fiber cable is carried out fast rapid-result end processing of realizing, the present invention has realized repeating, can repair, can safeguarding of optical fiber quick connector, is a kind of novel optical fiber quick coupler with high reliability.
Pre-buried fiber type optical fiber quick coupler takes following technical scheme to realize:
Pre-buried fiber type optical fiber quick coupler comprises pre-buried optical fiber align and clamping device, optical fiber importing and optical fibre clip gripping member, tail cover, SC type joints of optical fibre joint outer cover and joint end face dust cap; Described pre-buried optical fiber align and clamping device comprise that integral housing, ceramic insertion core, pre-buried optical fiber, gradual change footpath optical fiber import part, integrated of V groove butt joint, clamping crimp, spring and optical fiber clamping opening tool.Pre-buried optical fiber dress is inserted in the ceramic insertion core, and ferrule endface one side has joint end face dust cap, and the ceramic insertion core opposite side is fixed on integrated front end of V groove butt joint, and integrated rear end of V groove butt joint is fixed with gradual change footpath optical fiber and imports part; The clamping crimp docks integrated formation with the V groove withholds locking mechanism, and optical fiber clamping opening tool is used for the clamping crimp and docks integrated separating with the V groove; Integrated of V groove butt joint, reducing optical fiber import part and adopt integral housing to fix, and optical fiber clamping opening tool hangs card and is put in the corresponding tapping of integral housing, as convenient carrying of widgets.Optical fiber importing and optical fibre clip gripping member are crimped on the core members integral housing of pre-buried optical fiber align and clamping device, in the middle of spring is positioned at, and SC type joints of optical fibre joint outer cover on the outer cover, the tail cover is enclosed within the integral housing rear portion.The clamping crimp can separate and can take off by optical fiber clamping opening tool with integrated of V groove butt joint, the optical fibre refractivity that is used to annotate coupling cream, realize that optical fibre refractivity mates cream and repeatedly safeguards filling, eliminated the probable life worry that optical fiber quick connector is caused because of matching materials.
Principle of work
The on-the-spot use of pre-buried fiber type optical fiber quick coupler is: being ready to be correlated with (only needs cutter, the coat wire-stripping pliers, the sheath hoe scaler) instrument, with the tail cover be inserted in will Cheng Duan optical cable, stripping fiber optic cables, with Miller pincers (coat hoe scaler) released part optical fibre packages coating, cut away part optical fiber, the optical cable of well cutting optical fiber pushed that optical fiber imports and optical fibre clip gripping member position during to the coat raised position, take off optical fiber clamping opening tool, press behind the clamping crimp to optical cable being retreated to raised position and disappear, the tail cover is packed into rotational lock, and putting SC type joints of optical fibre joint outer cover is complete operation.
When repeating to open, earlier SC type joints of optical fibre joint outer cover is taken off, after with optical fiber clamping opening tool clamping crimp and integrated of V groove butt joint being separated then, behind the rotation tail cover optical fiber cable extraction is got final product, making step can be installed then make again.
When carrying out periodic maintenance, when repeating to be opened into integrated of clamping crimp and V groove butt joint and separate, adopt the clamp instrument that the clamping crimp is taken down from integrated of V groove butt joint, after groove filling matching fluid, again the clamping crimp is aimed to press and finish attended operation.
Pre-buried fiber type optical fiber quick coupler characteristics:
Pre-buried fiber type optical fiber quick coupler is disposed for Fiber to the home a kind of novel high-end repeating is provided, and can repair, the maintainable high-quality on-the-spot passive device that becomes to hold optical fiber quick connector, and this product has following characteristics:
