Abstract
The invention discloses a processing and assembling process of an optical fiber connector. The processing and assembling process includes the following steps that a lock block and a ceramic ferrule are assembled together, two end face oblique angles of the ceramic ferrule are ground, the ceramic ferrule is installed in an open bushing, press fit is conducted on a front cover, and then a press fit finished product is taken out. By the adoption of the assembling process of the optical fiber connector and the processing process of the two end face oblique angles of the ceramic ferrule, return losses of the optical fiber connector can be increased, processing efficiency is higher, and production cost is reduced.
Description
Technical field
The invention belongs to optical communication system field, be specifically related to a kind of processing and assembling of the joints of optical fibre.
Background technology
The joints of optical fibre are one of interface units commonly used in optical communication system.The major parameter of general measurement joints of optical fibre product quality performance is insertion loss and return loss.Because the sphere normal of the ferrule endface of APC type and the axis of fiber cores have the inclined-plane of an angle (being generally 8 °), the light signal let out can be allowed in optical signal transmission process to return fibre core from slant reflection, thus improve the return loss of connector, this inclination angle is all set in the both ends of the surface of the ceramic insertion core of APC type and more can significantly improves return loss, but the form and position tolerance between the inclination angle at two ends add be very difficult to man-hour ensure, processing and assembling provided by the invention can address this problem.
Summary of the invention
The object of the invention is to the deficiency overcome in prior art, a kind of processing and assembling of the joints of optical fibre is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A processing and assembling for the joints of optical fibre, comprises the steps:
Briquetting and ceramic insertion core are assembled together by step 1)
By fixing briquetting to the location, lower surface of briquetting and the method for shaft shoulder location and sidewall location on auxiliary mould, then ceramic insertion core being pressed in briquetting, then removing auxiliary mould;
Step 2) milled ceramic lock pin two end face oblique angles
By the briquetting that is press-fitted in described step 1) together and ceramic insertion core clamping on grinding clamp, and by fixing the shaft shoulder location of briquetting and the method for sidewall bearing pin location, then an end face inclination angle of milled ceramic lock pin, by the inclination angle, other end of milled ceramic lock pin again after grinding clamp integrated overturn 180 ° behind ground one end, after having ground, remove grinding clamp again;
Step 3) loads split coupling
Split coupling is loaded by the mode that ceramic insertion core lateral wall is located and briquetting lower surface is spacing;
Step 4) is press-fitted protecgulum
By fixing to the mode of briquetting shaft shoulder location and sidewall location the briquetting, ceramic insertion core and the split coupling that have been assembled together on auxiliary mould, on the auxiliary mould of split coupling lower end by the protecgulum shaft shoulder location and split coupling sidewall location and the protecgulum inwall shaft shoulder under spacing mode, the combination of briquetting, ceramic insertion core and split coupling is press-fitted into downwards on protecgulum;
Step (5) takes out the finished product be press-fitted
Take off auxiliary mould, take out the finished product be press-fitted.
The invention has the beneficial effects as follows:
The processing technology at the joints of optical fibre assembly technology designed by the present invention and ceramic insertion core Double End inclination angle, can improve the return loss of the joints of optical fibre, and working (machining) efficiency is higher, reduces production cost.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of instructions, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
