Summary of the invention:
In view of this, be necessary to provide a kind of simple in structure, with low cost and can in the opening quotation test job, accomplish the fiber alignment device of the provisional butt joint of optical fiber fast.
A kind of fiber alignment device comprises base, fibre core docking section and press section.The upper surface of base is provided with the locating slot of perforation, and the fibre core docking section is fixed in the locating slot; The fibre core docking section be provided with locating slot in the same way and the docking groove that connects, the groove position size of docking groove is by the diameter decision of fiber core; The press section is used for after two fiber cores are placed on docking groove and butt joint, covering the fibre core docking section, to keep two fiber core butt joints.
Preferably, the press section is connected with the base relative fixed through pivot.
Preferably, axle sleeve is set, on the upper surface of base, rotating shaft is set in the press section; Cooperation through axle sleeve, rotating shaft can be installed in the press section on the base; When two fiber cores be placed in the docking groove and butt joint after, the press section is that axle rotates with the rotating shaft, and then covers on the fibre core docking section.
Preferably, docking groove is any in rectangle cell body, semicircle cell body, " V " font cell body.
The fiber alignment device that the utility model provides comprises base, fibre core docking section and press section, is placed in the docking groove of fibre core docking section and after the butt joint, uses the press section to cover on the fibre core docking section at two fiber cores; To keep two fiber core butt joints; So can in the opening quotation test job, accomplish the butt joint of optical fiber fast, above-mentioned fiber alignment device is simply small and exquisite, need not power supply; Operating ambient temperature range is wide, is adapted at operation under the various environment; Simple to operate, low to the operators'skills requirement, need not special training; The production cost of fiber alignment device is merely about 1% of optical fiber splicer; Utilize the fiber alignment device to realize that fibre junction need not the pyrocondensation protection, the little core that continues is counted the used time of the every core of optical fiber and is about 58% of Fusion Joining, so saved the test duration.
