Set connection, the other end are placed in the middle part of ceramic sleeve, metal-coating are 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）, this inner interface is that the problem of adapter in PC or UPC faces is present is that Optical Return Loss is smaller, shadow
The transmission quality of optical signal is rung.
The content of the invention
The Optical Return Loss that the purpose of this utility model seeks to solve existing optical assembly adapter is smaller, influences optical signal
Transmission quality the problem of, there is provided a kind of double APC types optical assembly adapters.
Concrete scheme of the present utility model is：It is improved for existing optical assembly adapter, it has ceramic insertion core,

One end of core is connected with adapter sleeve, and the other end is placed in the middle part of ceramic sleeve, is equipped with the outer cover of adapter sleeve and ceramic sleeve
Metal-coating, it is characterized in that：The outer end coupling surface and inner interface of the ceramic insertion core are ground into APC faces, i.e. inclined plane,
And it is provided with location structure on metal-coating or indicates the telltale mark of interface incline direction, to ensure to dock with adapter
Connector interface it is consistent with the interface incline direction of ceramic insertion core be bonded to each other it is errorless.
The angle of inclination of APC faces described in the utility model is 6 ° or 8 °, or 9 °.
The incline direction of coupling surface described in the utility model and interface is consistent or reversed arrangement each other.
Location structure described in the utility model on metal-coating is positioning boss or detent.
Positioning boss described in the utility model or detent are to be located at the low side with ceramic insertion core butt end inclined plane
Or high-end side.
The utility model uses the docking mode of APC types, can greatly improve Optical Return Loss performance, improve optical signal
Transmission quality, and it is simple in construction, improving cost is low, and positioning is reliable, easy to operate.In the application, by the optical assembly of this APC types
The connector of adapter 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 also be groove）, one end and interface are the grooves in the optical assembly adapter external form of APC types（It can also be latch）Match somebody with somebody
Close, the latch or groove of the other end and APC type connectors（When for standard APC type connectors when be latch, off-gauge APC connects
Connect device and may be designed as groove）Coordinate, ensure that the interface of connector matches with the interface of this adapter and be connected, so as to realize
Effective connection of APC type optical assembly adapters and APC type connector ends, so as to realize effective connection of light path.
