Description
Technical field
The present invention relates to a kind of folder fibre devices for fibercuts test, belong to optical fiber detector technical field.
Background technique
Optical fiber is the important transmission medium in optical communication technique.The characteristic of optical fiber influences multiple sides that optical fiber is used and laid
Face, therefore be the important link of optical fiber cable production to the performance detection of optical fiber.Optical fiber in use, inevitably
Bear bending stress, it is therefore desirable to which bend fracture performance detection is carried out to optical fiber.Though existing at present have some fibercuts to survey
The device of examination, but it is used and test performance is also not satisfactory, it is difficult to meet the needs of production test.
Summary of the invention
Technical problem to be solved by the present invention lies in a kind of folder fibre device for fibercuts test is provided, it is not only
Folder is fine rationally, and test is accurate, and easy to use and operate.
The present invention be solves the problems, such as it is set forth above used by technical solution are as follows: including organic block, the side peace of base
Equipped with cantilever mounted, the other side of base corresponds to cantilever mounted and is provided with mobile cantilever, mobile cantilever and linear drive apparatus
It is connected, the first folder fibre slot is provided on the inside of cantilever mounted, the inside on mobile cantilever is correspondingly arranged the second folder fibre slot, and two
It presss from both sides fine slot to flush simultaneously in parallel, is installed on acoustic emission sensor in cantilever mounted or mobile cantilever.
According to the above scheme, the fine block of folder is installed in the cantilever mounted front end and mobile cantilever front end respectively, and the folder is fine
Slot setting is on pressing from both sides fine block.
According to the above scheme, the folder fibre slot is V-type straight trough, and the angle of V-type straight trough is 90 °.
According to the above scheme, the mobile cantilever is connected by slide with linear drive apparatus, is arranged on slide and base
Guide rail phase configuration, the linear drive apparatus is made of screw component and driving motor.
According to the above scheme, the moving direction of the mobile cantilever and the fine slot of folder are perpendicular.
According to the above scheme, movable sensor is provided on slide.
According to the above scheme, the acoustic emission sensor is miniature middle low frequency acoustic emission sensor.
The course of work of the invention are as follows: the fine slot of two folders is spaced a distance and is in static when device is in a state to be tested
The optical fiber for being bent 180 ° is put between two folder fibre slots by state, and fine slot, another side insertion are pressed from both sides in the insertion on one side first of curved fiber
Second presss from both sides fine slot, is then turned on the linear drive apparatus of mobile cantilever, so that mobile cantilever is with certain speed slowly to fixation
Cantilever is drawn close, and two spacing for pressing from both sides fine slots gradually become smaller, and is clamped in the radius of curvature of the fibre-optical bending section between two folder fibre slots also not
It is disconnected to reduce, until reaching the limit of fibre-optical bending to pinch off optical fiber, the fracture sound is issued, mobile cantilever is out of service.Optical fiber
When fracture, the acoustic emission sensor being fixed at cantilever design detects break signal, and records and two press from both sides between fine slots at this time
Away from as the minimum bend diameter of fibercuts namely the fragmentation parameters of fibre-optical bending.Thus a fibercuts reality is completed
It tests.
The beneficial effects of the present invention are: 1, structure setting reasonable, and optical fiber alignment is good during the fibre that breaks, and can accurately detect
To fibercuts signal and parameter.2, easy to use and operate, test process is adjustable, voice sending sensor high sensitivity.3,90 ° of V-types
Straight trough keeps optic fibre force more reasonable, and guarantees to fold when fibercuts.
Detailed description of the invention
Fig. 1 is the three-dimensional structure diagram of one embodiment of the invention.
Fig. 2 is the three-dimensional structure diagram of cantilever part in one embodiment of the invention.
Fig. 3 is the fibercuts signal detected.
Specific embodiment
Invention is further described in detail with reference to the accompanying drawings and embodiments.
Including organic block 5, the side of base is installed on cantilever mounted 13, and the folder fibre block of strip is installed in cantilever mounted front end
9, it presss from both sides and is provided with the first folder fibre slot on the inside of fine block, the other side of base corresponds to cantilever mounted and is provided with mobile cantilever 6, mobile outstanding
Arm is connected by slide 4 with linear drive apparatus, the guide rail phase configuration being arranged on slide and base, the linear drive apparatus
It is made of screw component 3 and driving motor 1.Driving motor is speed regulating motor, the movement speed of slide can be carried out it is arbitrary or
There is shelves adjusting, driving motor is connected by shaft coupling 2 with screw component.The fine slot of moving direction and folder of the mobile cantilever
It is perpendicular.It may be provided with movable sensor on slide, to record the moving parameter of mobile cantilever.Pacify in mobile cantilever front end
If the folder fibre block 7 of strip, the inside corresponding first for pressing from both sides fine block presss from both sides fine slot setting second and presss from both sides fine slot, and the fine slot of two folders is flushed and put down
Row, the folder fibre slot are V-type straight trough, and the angle of V-type straight trough is 90 °, depth 0.64mm.Two press from both sides placement bending between fine slot
Optical fiber 8, insertion presss from both sides fine slot.Acoustic emission sensor 12, the sound are installed on by pressing plate 11 and bolt 10 in cantilever mounted
