Conjunction makes male end localization region corresponding in the plugging direction with female end localization region.
The position of the fibre core of male end optical fiber is detected when male end optical fiber is arranged in male end contact pin and to male end localization region
It is marked, the position of the fibre core of female end optical fiber is detected when female end optical fiber is arranged in female end contact pin and to female end localization region
It is marked.
Male end contact pin has four male end regions, and female end contact pin has four female end regions, male end contact pin flange and female end
The outline of contact pin flange is square, and male end region is by the center line of male end contact pin and four ribs of male end contact pin flange
The line division on side is formed, and female end region is divided by the center line of female end contact pin and the line of four seamed edges of female end contact pin flange
Form.
The connector compound formulation of the present invention can accurately determine light by the way that contact pin is evenly dividing into multiple male end regions
The fine deflected position in contact pin is the position of male end localization region, and Male end connector is arranged in male end contact pin and female end contact pin
Reduce male end by the way that male end localization region and female end localization region are aligned in the plugging direction during with terminative connector and insert
Pin and the deflection of female end contact pin axial direction, reduce the light loss in fiber coupling, ensure the integrality of signal transmission.
Further, male end localization region and female end localization region are marked and are easy to optical fiber deflected position in contact pin
Determination, be easy to the determination of the circumferential position when contact pin is installed into connector case body to realize the alignment in grafting direction.
Brief description of the drawings
Fig. 1 is the assembling schematic diagram of optical fiber and contact pin in the prior art；
Fig. 2 is male end contact pin and Male end connector assembling schematic diagram.
Embodiment
The embodiment one of the connector compound formulation of the present invention：A kind of connector compound formulation, by male end contact pin vertical
Inserted in being evenly dividing in the plane of male end contact pin bearing of trend for two or more male end region, definition male end optical fiber installed in male end
The male end localization region of the fibre core region of male end optical fiber when in pin, when male end optical fiber is arranged in male end contact pin, detection is public
Hold the position of the fibre core of optical fiber and male end localization region is marked；By female end contact pin perpendicular to female end contact pin bearing of trend
Plane on be evenly dividing as the number female end region equal with male end areal, define female end optical fiber and be arranged on female end contact pin
The female end localization region of the fibre core region of female end optical fiber when interior, female end is detected when female end optical fiber is arranged in female end contact pin
Simultaneously female end localization region is marked for the position of the fibre core of optical fiber；Male end contact pin, female end contact pin are so being passed through into public affairs respectively
The positioning of end contact pin flange, female end contact pin flange and Male end connector housing, terminative connector housing can make male end when assembling
Localization region is corresponding in the plugging direction with female end localization region.
Wherein, the number in male end region is more, it is determined that fiber core position it is more accurate, in male end contact pin and female end contact pin
The axial deviation of male end optical fiber and female end optical fiber is with regard to smaller during docking, and light loss is with regard to smaller.In the present embodiment, connection is considered
The influence of the processing cost of device and the light loss of communicating optical signals to its performance, it is preferably four by male end region division, i.e.,
End contact pin has four male end regions, and female end contact pin has four female end regions.For the ease of division male end region and female end area
The outline of domain, male end contact pin flange and female end contact pin flange is square, male end region by male end contact pin center line
Formed with the division of the lines of four seamed edges of male end contact pin flange, female end region by female end contact pin center line and female end contact pin method
The line division of four blue seamed edges forms.
Specifically, as shown in Fig. 2 the periphery of male end contact pin 1 is provided with male end contact pin flange, the outline of male end contact pin flange
For square, by the center line of male end contact pin and the line of four seamed edges of male end contact pin flange by male end contact pin vertical
In being divided into tetra- male end regions of A, B, C, D in the plane of male end contact pin bearing of trend, load male end contact pin in male end optical fiber 2
When in endoporus 10, the male end region C of the fibre core deviation of male end optical fiber 2 is male end localization region, and in male end localization region, C institutes are right
Make marks on the one side in the quadrilateral periphery face for the male end contact pin flange answered, then assembled by male end contact pin in Male end connector
The male end optical fiber skew direction in it just can be substantially judged when on housing.Similarly method, mother is marked on female end contact pin
Hold the position of localization region.So, can adjust the circumferential position of female end contact pin by rotating when assembling terminative connector makes
Female end localization region in female end contact pin where female end optical fiber is corresponding in grafting direction with male end localization region C, thus subtracts
Small axial deviation between male end optical fiber and female end optical fiber, reduces light loss.
In the present embodiment, male end region and female end region are four and outer with male end contact pin flange and female end contact pin flange
The parameter of outline polygon is equal, in other embodiment, the outline of contact pin flange can be equilateral triangle or regular pentagon or
Regular polygon more than in Shuo Weiliu, correspondingly divide three or five or more than six regions equal with side number；Or
The outline of contact pin flange can be octagon, and zoning is four, or contact pin flange outline is regualr decagon,
And zoning is five, or contact pin flange outline is regular hexagon, and zoning is four etc., i.e. zoning
With the side number of the outline regular polygon of contact pin flange.
In the present embodiment, the deflected position of optical fiber is determined by optical fiber aligning instrument when optical fiber is arranged in contact pin
And made marks in the corresponding sides of the positive shape changeable of outline of contact pin flange, in other embodiments, can not be in contact pin flange
On make marks, measure a contact pin in optical fiber deflected position after be directly located in connector case body,
Now survey existing dress.
The connector compound formulation of the present invention can reduce the public affairs of Male end connector and terminative connector when to inserting in it
The axial deviation of optical fiber and female end optical fiber is held, light loss is greatly reduced, improves the performance of connector signal transmission.
