Description
Technical field
It is specifically double APC type optical assembly adapters the present invention relates to optic communication product technical field.
Background technology
The structure of the optical assembly adapter used in current optic communication mainly includes ceramic insertion core, in the outer of ceramic insertion core
Portion is set with adapter sleeve and ceramic sleeve, and adapter sleeve and ceramic sleeve are left and right docking arrangement, one end of ceramic insertion core and connection
Set connection, the other end is placed in the middle part of ceramic sleeve, and metal-coating is housed in the outer cover of adapter sleeve and ceramic sleeve.Existing
In technology, the inner face of ceramic insertion core（Outer face is coupling surface, and inner face is interface）For PC or UPC faces（I.e. end face is with
Heart line is arranged vertically）, the problem of this inner interface exists for the adapter in PC or UPC faces is that Optical Return Loss is smaller, shadow
The transmission quality of optical signal is rung.
The content of the invention
Present invention aim to which the Optical Return Loss for solving existing optical assembly adapter is smaller, the biography of optical signal is influenceed
The problem of transmission quality, there is provided a kind of pair of APC type optical assembly adapter.
The present invention concrete scheme be：It is improved for existing optical assembly adapter, it has ceramic insertion core, in pottery
The outer cover of porcelain lock pin is equipped with adapter sleeve and ceramic sleeve, and adapter sleeve and ceramic sleeve are left and right docking arrangement, ceramic insertion core
One end is connected with adapter sleeve, and the other end is placed in the middle part of ceramic sleeve, and metal is housed in the outer cover of adapter sleeve and ceramic sleeve
Overcoat, it is characterized in that：The outer end coupling surface of the ceramic insertion core and inner interface grind to form APC faces, i.e. inclined plane, and
The telltale mark provided with location structure or instruction interface incline direction on metal-coating, to ensure the company docked with adapter
The interface for connecing device is consistent with the interface incline direction of ceramic insertion core bonded to each other errorless.
The angle of inclination in heretofore described APC faces is 6 ° or 8 °, or 9 °.
The incline direction of heretofore described coupling surface and interface is consistent or reversed arrangement each other.
Location structure on heretofore described metal-coating is positioning boss or detent.
Heretofore described positioning boss or detent are to be located at the low side or height with ceramic insertion core butt end inclined plane
Hold side.
The present invention can greatly improve Optical Return Loss performance using the docking mode of APC types, improve the transmission of optical signal
Quality, and it is simple in construction, improving cost is low, and positioning is reliable, easy to operate.In the application, the optical assembly of this APC types is adapted to
The connector of device and APC types, is achieved a butt joint by docking with adapter sleeve, and docking is with being designed with two latches on adapter sleeve（
It can be groove）, one end and interface are the grooves in the optical assembly adapter external form of APC types（It can also be latch）Coordinate,
The latch or groove of the other end and APC type connectors（It is latch when for standard APC type connectors, off-gauge APC connectors
It may be designed as groove）Coordinate, it is ensured that the interface of connector matches with the interface of this adapter and is connected, so as to realize APC
Effective connection of type optical assembly adapter and APC type connector ends, so as to realize effective connection of light path.
