Description
Technical field
The present invention relates to the vibration abatement field, relate in particular to the shockproof encapsulation box of a kind of optical branching device.
Background technology
In the optical communication industry, boxlike PLC is widely used a kind of passive device, at boxlike PLC(Planar Light wave Circuit Splitter, planar optical waveguide splitter) in the production run, earlier naked device PLC is encapsulated in the steel pipe, more packaged PLC is encapsulated in the rectangular box.
In " China Telecom's passive optical splitter technical requirement ", the mechanical property of optical branching device requires: boxlike PLC needs to fall from height 1.8m, 3 axially, each is axial 8 times, circulate 5 times, falling back IL variable quantity is a pure digit less than 0.5dB(dB (Decibel, decibel), and original idea is the ratio size of two amounts of expression).
In the existing manufacturing technique, be that first PLC with packaged steel pipe is fixed on the inside that boxlike encapsulates box by AB glue with steel pipe, optical fiber penetrated in the blank pipe that diameter is 2.0mm again, may have following problem like this:
1, AB glue is to be mixed according to weight ratio 1:1 with B glue by A glue, is easy to mistaken ratio and causes glue to be pasted not strongly admittedly when preparation glue.
2, in operating process, optical cable is stained with glue easily since AB the glue solidifies can't wipe on optical cable, cause the PLC rectangular box directly to be scrapped.
3, be wound directly around in the rectangular box owing to optical fiber in the traditional handicraft, might cause the too small or distortion of fiber bending radius, thereby cause the PLC optical property defective.
4, boxlike PLC making basic working procedure is: the naked fine test-envelope steel pipe-dish rectangular box-Jia connector-optical performance test of PLC debugging-PLC.Because very hard after the AB glue curing if cause PLC bad when envelope steel pipe or dish rectangular box, do not detect at that time, follow-up being difficult to reprocessed.
5, in the traditional handicraft owing to be that loose dish is gone in the rectangular box, optical fiber rocks in box and causes optical fiber mixed and disorderly when doing drop test, thereby causes the PLC optical property to exceed standard.
6, very crisp firmly after the AB glue curing, as boxlike PLC during from 1.8 meters high-altitude drop, very big of impulsive force, cause steel pipe and encapsulation box to come off, steel pipe rocks when falling again, thereby causes steel pipe to pull optical fiber, finally causes the IL converted quantity greater than 0.5dB or single fiber fracture.
