Technical field
The present invention relates to optical fiber communication technology field, be specifically related to the structure aspects of passing through of fibre-optical splice.
Background technology
In recent years, optical fiber telecommunications system develop rapidly, is widely used in the industry-by-industry in communication system, and optical device, optical module, laser instrument etc. be as the important component part of optical fiber telecommunications system, and market demand increases day by day.Enhance productivity and become important task at present with quality.And the Tong Guangchu of seal casinghousing is very important operation in these products, affect the production efficiency of product, yield rate and product quality.
At present, the logical photo structure of separate type of existing a kind of seal casinghousing, as shown in Figure 1, comprise seal casinghousing 1, lens 2, diaphragm 3, fibre-optical splice 4 is again receptacle, fibre-optical splice 4 comprises outer protection metalwork 41, the ceramic disrance sleeve 42 that outer protection metalwork is 41 li and ceramic insertion core 43; Fibre-optical splice 4 is for pegging graft for input and output joint 5.After the lens 2 of seal casinghousing 1 the inside and other parts are fixed, need to pass through coupled fiber joint 4, be then welded on seal casinghousing 1.Because lens 2 internal components such as grade are present in the orientation problem of seal casinghousing 1, more difficult while causing coupled fiber joint 4, there is location and angle problem.Diaphragm 3 is used for sealing light hole.Therefore cause production efficiency low, yield rate is hovered all the time and can not be improved in certain level.
Summary of the invention
The utility model is mainly that the logical photo structure of separate type in order to solve existing seal casinghousing exists fibre-optical splice and Lens Coupling difficulty large, and production efficiency is low, the technical deficiency that yield rate is low, and the integrated fiber joint that proposes a kind of seal casinghousing leads to photo structure.
The technical matters proposing for solving the utility model, the technical scheme adopting is: a kind of logical photo structure of integrated fiber joint of seal casinghousing, include seal casinghousing, in seal casinghousing, be provided with lens, on seal casinghousing, be provided with light hole with lens correspondence position, the outside of light hole is provided with fibre-optical splice; Described fibre-optical splice includes the outer protection metalwork being connected with seal casinghousing, is provided with ceramic disrance sleeve in outer protection metalwork, in ceramic disrance sleeve, is provided with ceramic insertion core; It is characterized in that: described ceramic insertion core front end is in light hole extends to seal casinghousing, and by the optically-coupled that is coaxial docking of a ceramic joint sleeve and described lens.
Described ceramic joint sleeve and the aligning positioning precision of ceramic insertion core are 1um magnitudes.
Outer protection metalwork and the housing of described fibre-optical splice are welded and fixed, and the precision being welded and fixed is in 0.1mm magnitude.
The beneficial effects of the utility model are: the utility model adopts the ceramic insertion core in the fibre-optical splice in common process is done longlyer, can directly from light hole, be inserted in housing, make fibre-optical splice to set up high-precision position and angular relationship with housing, with ceramic joint sleeve by lens and ceramic insertion core coaxial positioning, make lens also set up high-precision position and angular relationship with housing, remove complicated coupled fiber joint operation from, make technique simpler, be conducive to assembling, improved production efficiency.Ceramic insertion core in fibre-optical splice has more close contact area with seal casinghousing, has the more sealing property of high reliability, the quality of improving product.
Accompanying drawing explanation
Fig. 1 is the structural representation of the logical photo structure of existing fiber joint;
Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and the preferred specific embodiment of the utility model, structure of the present utility model is further described.
Shown in Fig. 2, the utility model includes seal casinghousing 1, is provided with lens 2 in seal casinghousing 1, on seal casinghousing 1, is provided with light hole with lens 2 correspondence positions, and the outside of light hole is provided with fibre-optical splice 4; Described fibre-optical splice 4 includes the outer protection metalwork 41 being connected with seal casinghousing 1, is provided with ceramic disrance sleeve 42 in outer protection metalwork 41, in ceramic disrance sleeve 42, is provided with ceramic insertion core 44; Described ceramic insertion core 44 front ends are in light hole extends to seal casinghousing 1, and by the optically-coupled that is coaxial docking of a ceramic joint sleeve 7 and described lens 2.Pottery joint sleeve 7 is used for fixing lens 2 and ceramic insertion core 44.
Ceramic insertion core 44 in the utility model fibre-optical splice 4 will do longlyer than conventional ceramic insertion core, can directly insert from the light hole of seal casinghousing 1, make fibre-optical splice 4 to set up high-precision position and angular relationship with seal casinghousing 1, realize the beam direction of fibre-optical splice and seal casinghousing 1 inside simultaneously, form the position alignment precision of um level and the angular alignment accuracy of 0.02 degree.
Pottery joint sleeve 7 is 1um magnitude (um=micron=10exp(-6) rice with the positioning precision of aiming at of ceramic insertion core 44), and the precision that fibre-optical splice 4 is welded and fixed on seal casinghousing is at 0.1mm magnitude (10exp(-4) rice), that is to say that positioning precision has improved 100 times.
Meanwhile, because ceramic sleeve has certain length (such as 3mm is long), the angular alignment accuracy that can realize is so exactly 0.02 degree (arctan(1um/3mm)).And the angular alignment accuracy of conventional production process can only arrive 0.5 degree, that is to say that angle precision has improved 25 times.
Installation process, first the outer protection metalwork 41 of fibre-optical splice 4 can be fixed on seal casinghousing 1 outer wall by modes such as welding, rubber seal connections; Then ceramic joint sleeve 7 is socketed with ceramic insertion core 44; Afterwards lens 2 are put into ceramic joint sleeve 7, lens 2 are coaxially set in ceramic joint sleeve 7 with ceramic insertion core 44.
Because ceramic insertion core 44 can be set up high-precision position and angular relationship with seal casinghousing 1, lens 2 are coaxially arranged in porcelain bushing 7 with the ceramic insertion core 44 in fibre-optical splice 4, also set up high-precision position and angular relationship with seal casinghousing 1, therefore just removed the operation of complicated coupled fiber joint 4 from, make assembling more simple, enhance productivity.In addition, the ceramic insertion core 44 in fibre-optical splice 4 has more close contact area with seal casinghousing 1, guarantees the more sealing of high reliability, improves the quality of product.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
