Description
Technical field
The present invention relates to a kind of interface laser technique, more particularly to a kind of DINd type interface laser.
Background technology
To meet customer need, I newly devises a interface laser, the interface laser and rear class Transmission Fibers
Connected mode use DINd type interface connected mode, therefore be referred to as DINd type interface laser；DINd type interface laser master
To include housing, ceramic core, positioning pipe and TO lasers；The effect of ceramic core is that the output light of TO lasers is oriented to,
Limit chamber in positioning pipe and housing is used to carry out grafting guiding and positioning to the connector in rear class Transmission Fibers, to make
With, while also enable ceramic core to be accurately aligned with connector and (optical fiber, the end of rear class Transmission Fibers are integrated with ceramic core
It is arranged in the plug division on connector, ceramic core is aligned with connector, and the optical fiber substantially in ceramic core transmits with rear class
Optical fiber align), the optical signal for allowing DINd type interface laser to export low can be conducted damply.
At the beginning of design, it is contemplated that grafting convenience, the internal diameter of limit chamber is designed as into 2.6mm (ceramic core and plug division
External diameter be 2.5mm), the axial length of positioning pipe is designed as 5mm；Found in trial-manufacturing process, exemplar qualification rate is relatively low, makes
Into qualification rate it is low the reason for be mainly that ceramic core and connector alignment are poor, cause rear class Transmission Fibers export optical signal decline
Subtract larger.
The content of the invention
The problem of in background technology finds after being analyzed, and the dimensional parameters in initial design are in itself and invariably
It is appropriate, but in actual production, due to technological reason, cause the structural parameters of all parts certain error to be more or less present,
Then, inventor considers to offset negative effect caused by fabrication error by changing the structural parameters on device, therefore, hair
A person of good sense has carried out following analysis：
In DINd type interface laser, because ceramic core and housing are relatively fixed, therefore, it is necessary to the subject matter solved
It is the orientation problem of plug division；The plug division of outside insertion relies primarily on limit chamber and positioning pipe to be positioned, initial analysis
Think, the factor impacted there may be three, the horizontal stroke of the fore-and-aft distance deviation of plug division and ceramic core, plug division and ceramic core
To the angular deviation of skew, plug division axial direction and ceramic core axial direction；
DINd type interface laser model is established using the design of ZEMAX non-sequence, passes through three kinds of factors pair of analysis of simulation experiment
The influence of optical power attenuation；Separately adjustable to three kinds of factors progress during emulation experiment, detection various factors change is to light work(
The influence of rate decay：During separately adjustable fore-and-aft distance deviation, fore-and-aft distance deviation is set gradually to increase, the results showed that, fore-and-aft distance
Deviation need to reach 5.25mm, and luminous power can just be reduced to 32uw, and in practical structures, the gap between ceramic core and plug division compared with
It is small, it is less likely to reach 5.25mm, therefore, fore-and-aft distance deviation influences optical power attenuation smaller；Separately adjustable lateral shift
When, lateral shift is gradually increased, for lateral shift from during 1um is changed to 8um, optical power attenuation change is more slow,
When lateral shift is 8um, luminous power 46uw, but when lateral shift reaches 9um, luminous power only has 25uw, therefore, laterally
Skew has a great influence to optical power attenuation, need to control lateral shift in below 8um；During separately adjustable angular deviation, make angle
Deviation gradually increases, and from during 1 ° is changed to 15 °, optical power attenuation is slower for angular deviation, when angular deviation is 15 °,
Luminous power is 161uw, is continued after increasing angular deviation, and optical power attenuation change starts to accelerate, when angular deviation is 16 °, light
Power only has 6uw, and therefore, angular deviation has a great influence to optical power attenuation, need to control angular deviation in the range of 15 °；Root
Understood according to the structure of DINd type interface laser, when connector is plugged in DINd type interface laser, the grafting on connector
The middle part in portion is carried out spacing by limit chamber, and the plug division on the right side of limit chamber is carried out spacing by positioning pipe, therefore, influences lateral shift
Principal element with angular deviation is the internal diameter of limit chamber and the axial length of positioning pipe；Limit chamber internal diameter is bigger, and plug division exists
Play space in the radial direction is bigger, it is therefore desirable to reduces limit chamber internal diameter, for positioning pipe, it relies primarily on gold
Category material deformation recovery power come to plug division carry out it is spacing, the contact area of positioning pipe and plug division is bigger, and position-limiting action is just
It is better, on the contrary it is poorer, therefore, the position-limiting action of positioning pipe can be strengthened by extending the axial length of positioning pipe；Before being based on
Consideration is stated, inventor has carried out lot of experiments, and is finally obtained following technical scheme：
A kind of DINd type interface laser, the DINd type interface laser include housing, ceramic core, positioning pipe and TO laser
