Fig. 1 is a schematic structural view of the present invention.
Fig. 2 is a schematic perspective sectional view of a ceramic ferrule flange according to the present invention.
FIG. 3 is a schematic view showing a state in which a ceramic ferrule and a ceramic ferrule flange are forcibly fitted in the present invention.
FIG. 4 is a schematic view showing a state where the ceramic ferrule and the ceramic ferrule flange are brazed according to the present invention.
Detailed Description
The technical solution of the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
Referring to fig. 1 and 2, the brazing type ceramic ferrule assembly structure of the present invention includes a ceramic ferrule 1 and a ceramic ferrule flange 2, wherein the ceramic ferrule 1 has a fiber hole for passing an optical fiber therethrough at a center thereof, the ceramic ferrule flange 2 is provided therein with a fiber channel 21 for passing the optical fiber therethrough and a mounting hole 22 at a front end of the fiber channel for inserting the ceramic ferrule, the mounting hole is located at the front end of the ceramic ferrule flange and is communicated with the fiber hole.
The mounting hole 22 includes the strong dress hole 221 that is located the mounting hole rear end and is used for with ceramic contact pin 1 forced fit that is connected and be located the strong dress hole front end and be used for with ceramic contact pin brazing fixed section 222 of brazing, as preferred, the design has first direction chamfer 223 in the junction of strong dress hole and brazing section to play the guide to insert the effect of combining when inserting strong dress hole to ceramic contact pin by force, and the mounting hole front end is equipped with the second direction chamfer 224 that is located brazing section front end, also can play the guide effect when ceramic contact pin inserts the mounting hole. Dress hole 221 communicates with fiber channel 21 and the aperture in dress hole slightly is less than ceramic contact pin 1's external diameter by force, so that realize ceramic contact pin's the forced fit, the aperture of the section of brazing 222 is greater than dress hole 221 and ceramic contact pin 1 external diameter by force, ceramic contact pin dress by force is formed after the hole is adorned by force and is held brazing filler metal 23's annular space between the section of brazing, the brazing filler metal is filled the back and is made brazing filler metal melt, it is fixed to treat the brazing filler metal and accomplish brazing between ceramic contact pin and the ceramic contact pin flange after the condensation, and guide section 223 is that mounting hole front end processing chamfer formed, can ensure ceramic contact pin's smooth installation.
The ceramic pin flange 2 in this embodiment is preferably made of stainless steel, and the brazing filler metal filled in the brazing section 222 for achieving brazing fixation of the ceramic pin and the ceramic pin flange is preferably made of copper-silver alloy.
As shown in fig. 3, during installation, firstly, the ceramic pin 1 is forcibly installed into the installation hole 22 by using a tool, and at this time, the rear end of the ceramic pin 1 is in interference fit with the forcible installation hole 221 so as to ensure the installation position of the ceramic pin; with reference to fig. 4, the brazing filler metal 23 is filled in the brazing section 222 of the mounting hole of the ceramic ferrule flange, the brazing section 222 is locally heated (the heating area is the area indicated by the dashed line frame in fig. 4), the brazing filler metal is melted for welding, and since the melting point of the brazing filler metal is lower than that of the ceramic ferrule and the ceramic ferrule flange, a stable welding and fixing relationship can be formed after the brazing filler metal is condensed. Because the conventional assembly mode is that the ceramic contact pin is forcibly installed in the installation hole of the ceramic contact pin flange, the interference magnitude is very small, when the temperature rises, the expansion magnitude of the ceramic contact pin flange is greater than that of the ceramic contact pin, the forcible installation effect is weakened, and the failure of the optical fiber connector is easy to occur; in addition, stress formed by forced mounting can disappear along with aging along with time delay, but the welding mode adopted by the invention cannot cause the situation; in conclusion, the assembly structure provided by the invention has a good environmental stress resistance effect, and the assembly strength between the ceramic contact pin and the ceramic contact pin flange is greatly improved in a high-temperature variable and high-irradiation working environment.
The above description is only a preferred embodiment of the present invention, and any person skilled in the art can make any simple modification, equivalent change and modification to the above embodiments according to the technical essence of the present invention without departing from the scope of the present invention, and still fall within the scope of the present invention.
