It is constituted with following:
This is applied to the shell flange light guide structure in GPON optical network unit, including outer housing and flange light-guiding pillar, institute
The fiber outlet portion that wall portion is provided with disk fibre slot and is connected with the disk fibre slot on the inside of the outer housing stated, is mainly characterized by, institute
The one end for the flange light-guiding pillar stated and fiber outlet portion, which are integrally formed, to be connected and is connected, and the flange light-guiding pillar fit closely in
Outer housing inner sidewall.
The diameter of flange light-guiding pillar in the shell flange light guide structure being applied in GPON optical network unit can be situated between
Between 5.40mm~7.40mm.
Further, the straight of the flange light-guiding pillar in the shell flange light guide structure in GPON optical network unit should be applied to
Diameter is 6.40mm.
The length of flange light-guiding pillar in the shell flange light guide structure being applied in GPON optical network unit can be situated between
Between 8.25mm~10.25mm.
Further, the length of the flange light-guiding pillar in the shell flange light guide structure in GPON optical network unit should be applied to
Degree is 9.25mm.
Using the shell flange light guide structure of the utility model being applied in GPON optical network unit, due to wherein leading to
It crosses in-mould injection mode and flange light-guiding pillar is connected with shell, prevent noise caused by shaking because of flange and signal is bad, effectively
Solve the problems, such as that flange easily shakes and cause abnormal sound, simple and practical in structure, convenient manufacturing process, while this design it is possible to prevente effectively from
The work that ring flange is individually opened, so that production cost is significantly reduced, stable and reliable working performance；Compared to existing product, lead
The smaller of light flange column ingeniously effectively reduces installation space, is conducive to product miniaturization, meets appearance esthetic requirement, makes outer
More neat and artistic, promotion user experience is seen, the scope of application is relatively broad.
