Detailed Implementation

[0024] This utility model embodiment provides a repairable fiber optic ferrule adapter and its dedicated fixture, thereby enabling the repair of fiber optic ferrule adapters and improving product yield.

[0025] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figure 1 and Figure 2As shown, the repairable fiber optic adapter provided in this embodiment includes: a fiber optic connector 1, a cylindrical base 2, an open sleeve 3, and a cylindrical cap 4; the fiber optic connector 1 is snapped into the cylindrical base 2, and the end face of the fiber optic connector 1 extends out of the first end of the cylindrical base 2; an annular groove structure 5 is formed between the inner wall of the first end of the cylindrical base 2 and the outer wall of the fiber optic connector 1; the first end of the open sleeve 3 is snapped into the annular groove structure 5; the first end of the cylindrical cap 4 is snapped onto the outside of the cylindrical base 2 and the open sleeve 3; a connecting flange 6 is provided on the outer wall of the cylindrical cap 4. The connecting flange 6 is used to connect to the mounting groove of an external optical engine module.

[0027] To allow for additional space for adhesive reinforcement and increase product reliability, the outer wall of the first end of the cylindrical base 2 has a chamfered structure 7.

[0028] In this embodiment, the engagement friction between the fiber optic ferrule 1 and the cylindrical base 2 is between 50N and 70N, thus preventing the fiber optic ferrule 1 from separating from the cylindrical base 2 after mating. The engagement friction between the open sleeve 3 and the annular groove structure 5 is between 3N and 5N, thus ensuring that the inner wall of the annular groove structure 5 holds the outer wall of the open sleeve 3, preventing the open sleeve 3 from detaching. The engagement friction between the cylindrical cap 4 and the cylindrical base 2 and the open sleeve 3 is between 30N and 70N, thus preventing the cylindrical cap 4 from detaching.

[0029] like Figure 3 , Figure 4 and Figure 5 As shown, the special clamp provided in this embodiment of the utility model is applicable to the repairable fiber optic adapter as described above, including: a cylindrical support 8, an upper cap 9, a pin 16, and a force-applying device; an inner hollow groove 10 is formed from the bottom end to the top end of the cylindrical support 8, and an inlet / outlet groove 11 extends from the side wall of the cylindrical support 8 towards the center; a through hole of different diameters is provided at the center of the end face of the upper cap 9; the large diameter through hole 12 of the through hole is located at the bottom end of the upper cap 9, and the small diameter through hole 13 of the through hole is located at the top end of the upper cap 9. The diameter of the groove 11 is greater than the width of the groove 11; the cap 9 is fastened to the top of the cylindrical support 8; the width of the groove 11 is less than the inner diameter of the first end of the cylindrical cap 4 and greater than the outer diameter of the cylindrical base 2; the diameter of the large diameter through hole 12 in the reducing through hole is greater than the diameter of the connecting flange 6 on the outer wall of the cylindrical cap 4; the fiber optic adapter can be set in the reducing through hole and located at the top of the cylindrical support 8; the ejector pin 16 can be inserted from the second end of the open sleeve 3 to apply pressure to the end face of the fiber optic adapter 1; the force application device can apply pressure to the ejector pin 16.

[0030] To prevent the fiber optic adapter from shaking during pressurization and to improve stability, the diameter of the small-diameter through-hole 13 in the reducing through-hole is slightly larger than the outer diameter of the cylindrical cap 4.

[0031] To increase the stability between the upper cap 9 and the cylindrical support 8, the upper cap 9 is snapped onto the top of the cylindrical support 8, and the snapping friction between the inner wall of the upper cap 9 and the outer wall of the cylindrical support 8 is between 3 and 5 N, thereby achieving a sliding fit.

[0032] To further increase the stability of the cylindrical support 8, the bottom end of the cylindrical support 8 has a flange 14.

[0033] In this embodiment, the force-applying device is a stamping press or a hammer.

[0034] The repair process of the repairable fiber optic adapter provided in this embodiment of the present invention will be described in detail below:

[0035] First, place the fiber optic adapter into the groove 11 on the side wall of the cylindrical support 8 and onto the top of the cylindrical support 8. Then, snap the upper cap 9 onto the top of the cylindrical support 8. At this point, the fiber optic adapter is in the through hole of the upper cap 9. Next, insert the ejector pin 16 from the second end of the open sleeve 3, pressing against the end face of the fiber optic adapter 1. Figure 6 As shown. After applying pressure to the ejector pin 16 through the punching head, the assembled body consisting of the fiber optic ferrule 1, cylindrical base 2, optical fiber 15, and open sleeve 3 is ejected, as... Figure 7 As shown. The mating body will fall into the inner hollow groove 10 of the cylindrical support 8 through the inlet / outlet groove 11, while the cylindrical cap 4 will be positioned in the through hole of the different diameter, as shown. Figure 8 As shown. Next, remove the upper cap 9, take out the detached cylindrical cap 4, and then take out the assembled body consisting of fiber optic ferrule 1 + cylindrical base 2 + optical fiber 15 + open sleeve 3. Manually pull out the open sleeve 3. At this time, the repairable end face 17 of the fiber optic ferrule 1 is exposed, as shown. Figure 9 As shown. After grinding the end face 17 to be repaired, it can be reassembled and used again, completing the repair process of the fiber optic adapter.

[0036] In summary, the embodiments of this utility model not only achieve convenient assembly, high installation reliability, and repairability, but also improve product yield.
