Technical field
The present invention relates to a kind of length control device for MT-MT multichannel connectors, it is a kind of assembling tool, belongs to
Optic communication device manufacturing field.
Background technology
Core devices optical transceiver in optical transceiver module is related to the interconnection of intermodule in an assembling process, because
Empty module is small, thus installation space it is smaller, it is necessary to accurately control optical transceiver length, often require that reach 0.1mm with
Interior tolerance, in the fabrication process still lack it is special determine the device of optical transceiver length, can not meet it is quick, accurate, batch
Measure the requirement of production.
The fixing device for being used for assembling optical transceiver module used before my company is as shown in Figure 1, 2.When in use, press
It is required that being first through product MT multi-mode standards lock pin 5, the multicore with MT boot 6 is arranged on fibre 7 and its both ends of the surface stretches out multicore row
Then the product put on is put into and is incorporated to groove in MT-MT lock pins limiting plate 1 and puts just for 1mm or so by the length of fibre 7；Use MT-
The fine pressing plate 3 of MT rows pushes down multicore row fibre 7, with hand propelled both sides MT-MT length limited block 2, according to the direction of arrow to centre
Mobile and close 5 end face of MT multi-mode standards lock pin, makes the rear end face of MT multi-mode standards lock pin 5 withstand MT-MT lock pins limiting plate 1
Boss；Travel directions are unclamped after being kept for 2 seconds to draw, and take the fine pressing plate 3 of MT-MT rows away, and take product away and be put into and cure in frock
.The shortcomings that this scheme is：The fine bending of row is likely to cause when promoting and compressing lock pin, the length of multicore row fibre 7 after release
It can rebound, product length can not be accurately controlled in tolerance, and product fraction defective is too high；
The applicant can also directly arrange worker to use vernier caliper measurement in some cases, but need to adjust length manually during measurement
Degree, makes length effectively to control, generally requires longer time, efficiency is too low, does not use this means easily.
The content of the invention
The goal of the invention of the present invention is：For above-mentioned problem, there is provided one kind is used for MT-MT multichannel connectors
Length control device.
The technical solution adopted by the present invention is such：
A kind of length control device for MT-MT multichannel connectors, including MT-MT length limiting plates, the MT-MT long
The spacing mounting tables of MT-MT are set at the top of degree limiting plate, the spacing mounting table both ends of MT-MT set boss, the spacing mounting tables of MT-MT
The groove for placing MT boot and multicore row's fibre is opened up on top surface, the step surface that depth and the multicore row of groove are fine is suitable, recessed
The both ends of the surface of groove are identical with the distance between corresponding boss side surfaces.
Preferably, the spacing mounting tables of MT-MT are T-shaped and its underpart cross section is not rounded symmetric shape, it is described
The T-slot for accommodating the spacing mounting tables of MT-MT, the spacing bottom of MT-MT length are opened up in MT-MT length limiting plates
Horizontal segment both lateral sides slot milling of the seat in the spacing mounting tables of MT-MT.Further preferably, the MT-MT spacing mounting tables
Laterally MT-MT is set to lift pin in the middle part of horizontal segment.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1st, production efficiency is high：Solve the difficult point that MT-MT multichannels connector length controls in production process, it is easy to operate, make
Length confirms that work step can be completed in 3~5 seconds, has saved the time, has improved efficiency, the efficiency of each product can improve
50%；
2nd, reliable product quality：The existing error phenomenon caused by multicore arranges fine bending of existing fixing device is avoided, it is real
Show and fast and accurately controlled length, product length qualification rate improves more than 20%, and consistent length improves product optical index
Use the stability of transmission.
