Abstract
This utility model relates to a kind of inclined hole optical fiber ceramic lock pin, and including lock pin body, lock pin body is cylinder, and lock pin body interior is provided with optic fibre hole, and described lock pin body includes inserting end and coupled end；The axes intersect of the axis of described optic fibre hole and lock pin body, and intersection point overlaps with the central point of coupled end end face；The axis of described optic fibre hole is 3.7 ° with the angle of the axis of lock pin body.The ceramic insertion core structure of this programme simplifies；Same performance indicator conditions reduces by 1 road focusing operation when coupling welding with BASE, effectively solve attenuation concordance and reduce loss effect.
Description
Technical field
This utility model relates to a kind of inclined hole optical fiber ceramic lock pin, belongs to optical-fibre communications apparatus field.
Background technology
Ceramic insertion core is optical fiber pigtail core component, and its optical fiber pigtail market demand is just along with wavelength-division multiplex technique (WDM)
Extensively application and constantly expand, cost pressure increases the most therewith.Traditional ceramic insertion core needs to focus together work when welding
Sequence, production cost is higher.It is thus desirable to research and development a kind of low cost, high-quality ceramic insertion core.
Summary of the invention
This utility model is for solving above-mentioned deficiency, it is provided that a kind of inclined hole optical fiber ceramic lock pin, the specific scheme is that
A kind of inclined hole optical fiber ceramic lock pin, including lock pin body, lock pin body is cylinder, and lock pin body interior is provided with optical fiber
Hole, described lock pin body includes inserting end and coupled end；The axis of described optic fibre hole and the axes intersect of lock pin body, and hand over
Point overlaps with the central point of coupled end end face.
Further, the axis of described optic fibre hole is 3.7 ° with the angle of the axis of lock pin body.
Further, described optic fibre hole is provided with horn mouth, and horn mouth is positioned at insertion end, bell-mouthed axis and optic fibre hole
Axis consistent.
Further, the lateral wall of described lock pin body is provided with flat position, and flat position is in the position near coupled end.
Further, a length of 0.6 ~ 1mm of described flat position.
Further, the thickness of described flat position is 0.1 ~ 0.2mm.
The useful point of this programme is,
1. structure simplifies；Same performance indicator conditions reduces by 1 road focusing operation when coupling welding with BASE, effectively solve light
Road decay concordance and reduction loss effect.
2. reduce and grind clamping error；It is effectively improved positioning precision, at original assembly gold by location, flat position abrasive disk
Belong to part excircle orientation benchmark lower angle precision improvement, be effectively improved reflection angle process capability.
3. stable performance；After assembling with metalwork than conventional common straight hole lock pin under same size power condition, tail optical fiber returns
Damage lifting 3 ~ 5dB.
4. under same performance indicator conditions, inclined hole lock pin comprehensively becomes with metalwork mounting assembly than conventional straight hole lock pin
This reduction by more than 8%.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
