[0039] See also Figures 1 to 3 In some embodiments of the present application, a protective sleeve 10 provided in the present application includes a main body 11, the main body 11 is cylindrical, and the main body 11 is provided with a guide groove 12 and a limit groove 13.

[0040] The guide groove 12 is located at the end of the main body 11 . The limiting groove 13 is located on the inner wall of the main body 11 .

[0041] In the process of sleeve-fitting the protective sleeve 10 onto the connector 20, the guide groove 12 is used for guidance, so that the protective sleeve 10 can be more smoothly sleeved into the connector 20, and the limiting groove 13 is used for limiting, so as to prevent the protective sleeve 10 and the connector 20 from rotating relative to each other during the sleeve-fitting process, so that the sleeve-fitting process is smoother.

[0042] In this way, the convenience of optical fiber wiring is improved.

[0043] See also Figures 1 to 6 In some embodiments of the present application, the number of the guide grooves 12 is two, and the guide grooves 12 are symmetrically arranged along the longitudinal mid-section of the main body 11.

[0044] In the process of sleeve-fitting the protective sleeve 10 on the connector 20, one end of the protective sleeve 10 provided with the guide groove 12 first meets the connector 20, and under the guidance of the guide groove 12, the protective sleeve 10 can be more smoothly sleeved into the connector 20. By providing the guide grooves 12 on both sides of the protective sleeve 10, and symmetrically arranging the guide grooves 12 along the longitudinal middle section of the main body 11, the guide grooves 12 can realize the guiding function from both sides, thereby preventing the protective sleeve 10 from deflecting during the relative sliding process with the connector 20, thereby reducing the risk of jamming, and enabling the protective sleeve 10 to be more smoothly sleeved into the connector 20.

[0045] In some embodiments of the present application, guide grooves 12 are provided at both ends of the main body 11 , and the guide grooves 12 are symmetrically arranged along the transverse mid-section of the main body 11 .

[0046] By providing guide grooves 12 at both ends of the main body 11 and symmetrically arranging the guide grooves 12 along the transverse mid-section of the main body 11, the protective sleeve 10 can be inserted into the connector 20 from both ends thereof, so that the staff does not have to distinguish which end of the protective sleeve 10 to insert, further improving the convenience of optical fiber wiring.

[0047] In some embodiments of the present application, the number of the limiting grooves 13 is two, and the limiting grooves 13 are symmetrically arranged along the longitudinal mid-section of the main body 11 .

[0048] The limiting groove 13 limits the connector 20 from both sides, so that the connector 20 is subjected to more uniform force when being inserted into the protective sleeve 10, reducing the risk of jamming, and allowing the protective sleeve 10 to be inserted into the connector 20 more smoothly.

[0049] In some embodiments of the present application, the orientation of the guide groove 12 and the orientation of the limiting groove 13 are perpendicular to each other.

[0050] By limiting the orientation of the guide groove 12 and the limit groove 13 , the connector 20 is subjected to more uniform force during insertion into the protective sleeve 10 , thereby reducing the risk of jamming and enabling the protective sleeve 10 to be inserted into the connector 20 more smoothly.

[0051] In some embodiments of the present application, the main body 11 is made of stainless steel.

[0052] The connector 20 is protected by the protective sleeve 10 made of stainless steel, so as to prevent the connector 20 from deformation or damage, and improve the protection reliability of the protective sleeve 10. The protective sleeve 10 is made of stainless steel material, which reduces the risk of corrosion of the protective sleeve 10 and improves the stability of the protective function of the protective sleeve 10.

[0053] In some embodiments of the present application, the material of the protective sleeve 10 can also be hard plastic, copper alloy, aluminum alloy or other materials with sufficient structural strength to ensure the reliability and stability of the protective function of the protective sleeve 10.

[0054] On the other hand, see Figures 4 to 6 In some embodiments of the present application, the present application further provides a connector 20 for connecting a first optical fiber component 30 and a second optical fiber component 40 , including a fixing sleeve 21 and a protective sleeve 10 .

[0055] The fixing sleeve 21 is used to fix the first optical fiber component 30 and the second optical fiber component 40 . The protective sleeve 10 is sleeved on the outer side of the fixing sleeve 21 .

[0056] A guide protrusion 22 and a limiting protrusion 23 are provided at the end of the fixing sleeve 21 . The guide protrusion 22 is matched with the guide groove 12 , and the limiting protrusion 23 is matched with the limiting groove 13 .

[0057] The first optical fiber component 30 and the second optical fiber component 40 are fixed by the fixing sleeve 21, thereby ensuring the reliability of the docking between the first optical fiber component 30 and the second optical fiber component 40. The protective sleeve 10 is sleeved on the outer side of the fixing sleeve 21, and then the fixing sleeve 21 is protected by the protective sleeve 10 to prevent the fixing sleeve 21 from deformation or damage.

[0058] When the protective sleeve 10 is inserted into the connector 20, the guide protrusion 22 first enters the guide groove 12, and then the guide protrusion 22 cooperates with the guide groove 12 to allow the connector 20 to smoothly enter the protective sleeve 10. Then the limiting protrusion 23 enters the limiting groove 13, thereby preventing the connector 20 from rotating during the process of entering the protective sleeve 10, thereby making the sleeve connection process smoother, thereby improving the convenience of optical fiber wiring.

[0059] In some embodiments of the present application, the fixing sleeve 21 is further provided with an opening groove 24 , the opening groove 24 extends from one end of the fixing sleeve 21 to the other end of the fixing sleeve 21 , and the guide protrusions 22 are provided on both sides of the opening groove 24 .

[0060] By providing the opening groove 24, the fixing sleeve 21 can be deformed. In the process of inserting the protective sleeve 10 into the connector 20, the guide protrusion 22 first enters the guide groove 12. In the process of the guide groove 12 guiding the guide protrusion 22, the inner wall of the protective sleeve 10 squeezes the guide protrusion 22, so that the fixing sleeve 21 is elastically deformed at the opening groove 24, so that the connector 20 can smoothly enter the protective sleeve 10. When the guide protrusion 22 passes the end away from the guide groove 12, the protective sleeve 10 stops squeezing the guide protrusion 22, so that the fixing sleeve 21 returns to its original shape, and the guide protrusion 22 hooks the end of the protective sleeve 10 to prevent the protective sleeve 10 from falling off the connector 20, thereby improving the stability and reliability of the combination of the protective sleeve 10 and the connector 20.

[0061] In some embodiments of the present application, the bottom end surface 25 of the opening groove 24 is an arc surface.

[0062] By setting the bottom end surface 25 of the opening groove 24 as an arc surface, when the fixing sleeve 21 undergoes elastic deformation, stress concentration is reduced, the structural strength of the fixing sleeve 21 is improved, and the stability of the connector 20 structure is further improved.

[0063] In some embodiments of the present application, guide protrusions 22 and limiting protrusions 23 are provided at both ends of the fixing sleeve 21 , and the position of the guide protrusion 22 corresponds to the position of the guide groove 12 , and the position of the limiting protrusion 23 corresponds to the position of the limiting groove 13 .

[0064] After the protective sleeve 10 is inserted into the connector 20, the limiting protrusions 23 at both ends of the fixing sleeve 21 cooperate with the limiting grooves 13 of the protective sleeve 10 to prevent the connector 20 and the protective sleeve 10 from rotating relative to each other, thereby improving the stability of the connector 20 structure, and further improving the reliability and stability of the docking of the first optical fiber component 30 and the second optical fiber component 40. The limiting protrusions 23 limit the connector 20 from both ends, so that the force on the connector 20 is more uniform.

[0065] After the protective sleeve 10 is inserted into the connector 20, the guide protrusions 22 at both ends of the fixing sleeve 21 are respectively abutted against the two ends of the protective sleeve 10, thereby preventing the connector 20 from moving inside the protective sleeve 10 and reducing the risk of the connector 20 falling out of the protective sleeve 10, thereby improving the stability and reliability of the combination of the protective sleeve 10 and the connector 20.
