[0023] Please refer to Figures 1 - 3 , for a further description of the embodiments of the present utility model;

[0024] An FC-type - LC-type adapter, comprising: an SC ceramic ferrule 1, a tailstock 3, an FC adapter rear seat 5, an LC ceramic ferrule 6, and an LC rear seat 8. The LC ceramic ferrule 6 and the SC ceramic ferrule 1 are respectively embedded in the left and right ends of the tailstock 3. The tailstock 3 and the LC ceramic ferrule 6 are installed in the FC adapter rear seat 5, and the end of the LC ceramic ferrule 6 passes through the FC adapter rear seat 5 and is installed in the LC rear seat 8. A split ceramic ring 7 is sleeved on the left end of the LC ceramic ferrule 6, and the split ceramic ring 7 is tightly connected to the inner part of the right end of the LC rear seat 8. A sealant is filled between the FC adapter rear seat 5 and the LC rear seat 8.

[0025] Wherein, an FC outer nut 4 is threadedly connected to the outside of the FC adapter rear seat 5, an FC inner sleeve 2 is embedded in the FC outer nut 4, the FC inner sleeve 2 is sleeved on the SC ceramic ferrule 1, the right end of the tailstock 3, and the right end of the FC adapter rear seat 5, and the outer end of the SC ceramic ferrule 1 extends out of the FC inner sleeve 2.

[0026] In addition, a spring 9 is installed in the FC inner sleeve 2, the spring 9 is sleeved on the right end of the tailstock 3, and the right end of the spring 9 abuts against the protruding part at the right end of the tailstock 3.

[0027] The manufacturing process of this adapter is as follows:

[0028] In the first step, the tailstock 3 is an important part of the fiber optic connector. First, the measured and cut optical fiber is inserted into the tailstock 3 and fixed, and then the end face of the optical fiber is polished to make it flat and smooth.

[0029] In the second step, the SC ceramic ferrule 1 and the LC ceramic ferrule 6 are respectively pressed into the left and right ends of the tailstock 3 and connected to the optical fiber. The SC ceramic ferrule 1 and the LC ceramic ferrule 6 are the core parts of the fiber optic connector, responsible for realizing the precise docking and signal transmission between optical fibers, and thus a semi-finished product is obtained.

[0030] In the third step, a split ceramic ring 7 is worn on the left end of the LC ceramic ferrule 6. Then, the spring 9 is installed in the FC inner sleeve 2. Then, the FC inner sleeve 2 is inserted into the left end of the FC outer nut 4. Next, the FC outer nut 4 is moved to sleeve the FC inner sleeve 2 on the right end of the FC adapter rear seat 5 and the FC outer nut 4 is rotated so that the FC outer nut 4 is threadedly connected to the outside of the FC adapter rear seat 5.

[0031] In the fourth step, glue is applied at the connection between the LC rear seat 8 and the FC adapter rear seat 5, and then it is inserted parallel into the inside of the FC adapter rear seat 5. At this time, the LC rear seat 8 is tightly sleeved outside the split ceramic ring 7. After the glue dries, a test is carried out, and when the product is qualified, the production is completed.

[0032] Compared with the prior art, the advantages of the present utility model are:

[0033] 1. The setting of the FC adapter rear seat 5 can not only prevent the end face of the LC ceramic ferrule 6 from being bruised, but also play a guiding role for the connecting piece inserted on the LC ceramic ferrule 6, facilitating the insertion and extraction of the connecting piece;

[0034] 2. The LC adapter (LC ceramic ferrule 6 and LC rear seat 8) adopts a modular jack (RJ) latch mechanism and has wide compatibility;
