Embodiment
A kind of embodiment of method for making of polarization maintaining optical fibre connector assembly is as shown in figs. 1 to 6: be described this method for making for four-core polarization maintaining optical fibre connector assembly below, polarization maintaining optical fibre connector assembly to be produced comprises adaptive plug 1 and socket 8, plug comprises the plug casing built with four contact pin components, each contact pin components includes the contact pin components housing 2 built with optical fiber contact pins 3, contact pin components housing is provided with the contact pin components fiber orientation key 4 for corresponding polarization-preserving fiber axis fixing assembling, socket comprises the Socket casing that front end is inserted terminal, four corresponding with each contact pin components respectively female part are installed in Socket casing, each female part includes the female part housing 14 built with fiber optic hub, fiber optic hub comprises optical fiber contact and is set in the porcelain bushing 7 of optical fiber contact periphery, female part housing is provided with the female part fiber orientation key 9 assembled for corresponding polarization-preserving fiber axis fixing, female part housing is also fixed with the locating sleeve 5 that coaxial cable is set in fiber optic hub periphery, locating sleeve is made up of metal material, the rear end of locating sleeve be provided with the locating sleeve of female part fiber orientation key positioning and plug-in mounting after positioning spline, the front end of locating sleeve is provided with the locating sleeve prelocalization keyway 6 with contact pin components fiber orientation key positioning and plug-in mounting, after locating sleeve prelocalization keyway and locating sleeve, the concentricity line of positioning spline is arranged.
The making side of polarization maintaining optical fibre connector assembly comprises the following steps, the first step, gang socket polarization maintaining optical fibre in female part, and the angle between the center line ensureing the female part fiber orientation key on the polarization axle of socket polarization maintaining optical fibre and female part housing
attachment plug polarization maintaining optical fibre on contact pin components, and the angle between the center line ensureing the contact pin components fiber orientation key on the polarization axle of plug polarization maintaining optical fibre and contact pin components housing
second step, jack locating sleeve coaxial cable being set in female part is peripheral, the two ends of locating sleeve have positioning spline after the locating sleeve prelocalization keyway and locating sleeve that concentricity line arranges, make positioning spline and female part fiber orientation key positioning and plug-in mounting after the locating sleeve on locating sleeve, then by contact pin components and female part grafting, and contact pin components fiber orientation key and locating sleeve prelocalization keyway is made to locate grafting, 3rd step, plug polarization maintaining optical fibre connects light source 16, extinction ratio tester 17 is connected accordingly on socket polarization maintaining optical fibre, if the reading of extinction ratio tester meets the requirements, locating sleeve is installed on female part housing by bonded structure, reading as extinction ratio tester is how many just to meet the requirements, this and plug, the length of socket polarization maintaining optical fibre is relevant, at plug, when the length of socket polarization maintaining optical fibre is within 2 meters, reading be greater than 20dB think qualified, certainly, when the length of polarization maintaining optical fibre is other value, have other reading standard, this reading standard belongs to prior art, be not described in detail in this, 4th step, loads plug casing and completes plug making by each contact pin components, each locating sleeve is loaded Socket casing with corresponding female part and completes socket making.
Due to locating sleeve be assembled to female part after the more difficult detection of precision, so can before locating sleeve does not install in female part, first carry out concentricity degree to the forward and backward positioning spline of the locating sleeve on locating sleeve and detect.
Polarization maintaining optical fibre to axle principle as shown in Figure 2: namely the line of centres of 12, two stressed zones, two stressed zones that polarization maintaining optical fibre comprises core 13 and is symmetricly set in core both sides is polarization axle 11, ideally the angle of polarization axle and the center line 10 of corresponding positioning key
when practical operation, need to be connected to polarization maintaining optical fibre on plug with the center line of contact pin components fiber orientation key for benchmark dead axle, make it to meet respective angles demand, need to be connected to polarization maintaining optical fibre on socket with the center line of female part fiber orientation key for benchmark dead axle, make it satisfied corresponding angle demand, then aiming at of contact pin components and female part is carried out by locating sleeve, before the locating sleeve at locating sleeve two ends, rear positioning spline coordinates with corresponding positioning key respectively, due to higher to the accuracy requirement of locating sleeve, before general detecting instrument is difficult to detection and location cover, the concentricity degree of rear positioning spline, so can at locating sleeve after the assay was approved, refill and be fitted in female part, and then debug together with contact pin components, light source 16 is passed through to input optical signal in corresponding polarization maintaining optical fibre in debugging, then the extinction ratio tester 17 being used for receiving optical signals is set at the opposite side of connector assembly, if extinction ratio tester display extinction ratio index reaches requirement, namely it is qualified to detect, by bonded structure, locating sleeve is bonded on female part housing, and then whole female part is assembled in socket, locating sleeve is the frock of debugging, it is again a part for female part, extinction ratio tester is a detection piece, do not need debugging, the make efficiency of polarization maintaining optical fibre connector assembly is high.Such design can be fallen the underproof loss of production debugging and is reduced to minimum, if extinction ratio is defective, whether the polarization axle that so we detect the corresponding plug polarization maintaining optical fibre with accurate measurement is respectively aimed at the center line of contact pin components fiber orientation key qualified, whether the polarization axle of socket polarization maintaining optical fibre is aimed at the center line of female part fiber orientation key qualified, and then whether the physical construction of the positioning spline on the both sides of detection and location cover meets the requirements.The contact pin components of standard, female part and locating sleeve can certainly be taken to carry out difference comparison, and can be found to the end is more fast which workpiece is defective.If find that in the process of debugging contact pin components is defective or female part is defective, or locating sleeve is defective etc., and situation can be changed in time, if each parts are all qualified, the plug be finally assembled into or socket all can have good optical property.Contact pin components, female part and locating sleeve all completed detection before being assembled to corresponding plug housing and Socket casing, contributed to like this controlling to minimum by scrapping the amount of money, human cost etc.
In other embodiment of this method for making, locating sleeve also can be made up of plastic material; In plug, the number of contact pin components can also be one, two or other number; Locating sleeve can also be fixed on female part housing by screw fixed sturcture; When detecting, also can connect extinction ratio tester on plug polarization maintaining optical fibre, on socket polarization maintaining optical fibre, connecting light source accordingly.
