[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Reference Figure 1-3 , a fiber optic connector with stable transmission, comprising a protective cover 1, an outer shell 2 and a fixed seat 3; the protective cover 1 comprises a rib 11, the outer shell 2 comprises a connecting tube 21, an annular positioning block 22 and a protective cover 23, and the fixed seat 3 comprises a threaded tube 31 and a movable groove 32; the rib 11 is located at the bottom of the inner side of the protective cover 1, the connecting tube 21 is located at the center position of the top of the outer shell 2, the annular positioning block 22 is located on the side wall of the outer shell 2 close to the connecting tube 21, the protective cover 23 is clamped on the connecting tube 21, and a threaded tube 31 is provided on the top of the fixed seat 3, and a movable groove 32 is provided on the threaded tube 31.

[0021] By passing the optical fiber through the fixing seat 3, the outer shell 2 is rotated and installed on the fixing seat 3. The thickness of the front side wall of the threaded tube 31 on the fixing seat 3 is greater than the thickness of its rear side wall. The optical fiber is clamped while the outer shell 2 is tightened to prevent the optical fiber from loosening. The anti-slip grooves 24 on the outer shell 2 facilitate the tightening work. A protective cover 23 is sleeved on the connecting tube 21 of the outer shell 2 to protect the connector. A protective cover 1 is sleeved on the outer shell 2. A first threaded sleeve 12 is provided on the inner wall of the protective cover 1. A rib 11 is provided inside the protective cover 1 so that the protective cover 1 can slide on the outer shell 2 without falling off. After the optical fiber is connected, the protective cover 1 can be tightened to protect the connection, which can prevent dust from entering and some external collisions from affecting the stability of the connection.

[0022] A first threaded sleeve 12 is provided on the inner side wall of the protective cover 1. The diameter of the annular positioning block 22 matches the inner diameter of the protective cover 1, and the annular positioning block 22 is clamped on the outer shell 2.

[0023] The inner wall of the protective cover 1 is provided with a rib 11, and the outer shell 2 is provided with an annular positioning block 22. First, the outer shell 2 is passed through the protective cover 1, and then the annular positioning block 22 is installed on the outer shell 2, so that the protective cover 1 slides on the outer shell 2 without falling off.

[0024] A second threaded sleeve 25 is provided at the bottom of the inner wall of the outer shell 2, and a circle of anti-slip grooves 24 are provided on the outer wall of the outer shell 2, so as to facilitate screwing the outer shell 2 onto the fixing seat 3.

[0026] The thickness of the front side wall of the threaded tube 31 is greater than the thickness of the rear side wall thereof, and the cross-section of the side wall of the threaded tube 31 is shown. When the optical fiber passes through the threaded tube 31, the front end of the front threaded tube 31 is squeezed outward. Tightening the outer shell 2 to the fixing seat 3 tightens the threaded tube 31, thereby clamping the optical fiber and preventing it from loosening.
