When the optical fiber connector is assembled, the mounting opening 33 of the inner pipe body 3 is aligned with the sliding block 42 of the rotating outer sleeve 4, then the rotating outer sleeve 4 is pushed axially to enable the sliding block 42 to slide into the yielding groove 34 through the mounting opening 33, the rotating outer sleeve 4 is rotated again, the second guiding surface 421 of the sliding block 42 abuts against the first guiding surface 311 and slides into the sliding groove 32 along the first guiding surface 311, the operation of the way of rotating and clamping after the insertion is convenient, and the assembly efficiency of the inner pipe body 3 and the rotating outer sleeve 4 can be effectively improved. Since the slide 42 can only slide back and forth in the circumferential direction of the inner tube body 3 in the slide groove 32, the swivel housing 4 is axially fixed relative to the inner tube body 3, but can swivel relative to it in the circumferential direction.
The slider 42 is further provided with a limiting surface 422 on the adjacent side of the second guiding surface 421. Because the interval arrangement of the chute 32 and the abdication groove 34 makes a separation step 35 exist between the chute 32 and the abdication groove 34, after the sliding block 42 slides into the chute 32 through the first guide surface 311, the limit surface 422 is propped against the groove wall of one side of the chute 32 close to the abdication groove 34, so that the sliding block 42 can only slide unidirectionally from the abdication groove 34 to the chute 32, thereby effectively preventing the sliding block 42 from sliding out of the chute 32 towards one side of the abdication groove 34, and increasing the structural stability when the rotary outer sleeve 4 and the inner pipe main body 3 rotate relatively.
The outer side wall of the inner pipe body 3 is also provided with a yielding port 36 on the convex ring 31, and the yielding port 36 is arranged at the joint of the sliding groove 32 and the yielding groove 34 and is opposite to the mounting port 33. Thus, the operator can observe the sliding of the slider 42 into the chute 32 through the relief opening 36. If the elastic element 7 cannot effectively abut against the sliding block 42, the tool can be inserted into the sliding groove 32 from the yielding port 36 to toggle the sliding block 42 or the elastic element 7 to a proper position, so that a good resetting effect of the elastic element 7 on the sliding block 42 is ensured.

For this purpose, the collar 31 is provided with a cutout 312 on one side of the slot 32, which cutout 312 reduces the contact area of the spring element 7 with the slot wall of the slot 32, as a result of which the wear of the spring element 7 is reduced. The collar 31 is further provided with a stepped groove 313 on the side of the slide groove 32 where the cutout 312 is provided, and the stepped groove 313 communicates with the slide groove 32. When the rotary sleeve 4 is sleeved outside the inner pipe main body 3, one side end part of the rotary sleeve 4 is clamped into the stepped groove 313, so that the rotary sleeve 4 can be prevented from being axially approaching the tail pipe 5, and the axial limiting effect of the rotary sleeve 4 and the inner pipe main body 3 is further improved.
Referring to fig. 5, the elastic member 7 of the present application is specifically a spring, which is based on the fact that the spring has the characteristics of large elastic deformation, good resetting effect and high resetting efficiency compared with other elastic members 7, and can quickly and effectively drive the slider 42 to reset. One end of the spring abuts against the slider 42, and the other end of the spring abuts against the groove wall of the chute 32 away from.

Therefore, the limiting block 43 slides in the limiting groove 38 to limit the circumferential rotation angle of the rotating outer sleeve 4 relative to the inner pipe main body 3, so that the rotating outer sleeve 4 is prevented from excessively rotating and exceeding the elastic deformation range of the elastic piece 7, and the good resetting effect of the elastic piece 7 can be ensured. In this embodiment, the limiting groove 38 is formed on the convex ring 31 between the sliding groove 32 and the yielding groove 34, and the structure of the limiting block 43 is identical to that of the sliding block 42 and is equidistantly arranged, so that the limiting block 43 and the sliding block 42 are located on two opposite sides of the same loop line of the rotating jacket 4, and the stability of the rotating jacket 4 and the inner tube main body 3 in relative circumferential rotation can be increased to a certain extent.

The limiting structure and principle of the limiting block 43 in the limiting groove 38 are the same as the above-mentioned principle of the sliding block 42 in the sliding groove 32, so that the description thereof will not be repeated here.
On the basis of the above embodiment, referring to fig. 6 and 7, one end of the inner tube main body 3 is provided with a ferrule holder 8, and a ferrule assembly is carried in the ferrule holder 8, and the ferrule assembly exposes a ferrule 9 for butt joint from one end of the ferrule holder 8. The center of the connecting seat 2 is provided with a jack 22 for inserting the insert core support 8, the jack 22 is approximately cuboid, but two adjacent vertex angles of the jack 22 are provided with an inclined unfilled corner 23, so that the insert core support 8 can be inserted into the jack 22 only along the same state.
The entire ferrule holder 8 is configured as an adapting structure having a shape similar to that of the insertion hole 22, so that the ferrule holder 8 can be inserted into the insertion hole 22 of the optical fiber adapter only in a fixed state, and thus, the entire ferrule holder 8 is also substantially rectangular and has two corresponding chamfer angles 81 corresponding to the two unfilled corners 23 in the insertion hole 22, and the ferrule holder 8 is also provided with two corresponding chamfer angles 81 on the corresponding portions.

Specifically, the inclined surface 83 is formed to be convex and located on the same spherical surface, and gradually increases in diameter in a direction away from the guide ring 82. Preferably, the inclined surface 83 is spherical in shape overall so that the ferrule holder 8 is still secured with a plurality of stable points of contact with the circumference of the receptacle 22 in the event of axial angular deflection.
Based on this, during the process of docking the optical fiber connector with the corresponding optical fiber adapter, the ferrule holder 8 is inserted toward the direction of the jack 22, the guide ring 82 is not constrained by the direction of the jack 22 and the ferrule holder 8, but enters the jack 22 first, but when the ferrule holder 8 and the jack 22 are not completely aligned, the ferrule holder 8 cannot be inserted into the jack 22 precisely, and at this time, the guide ring 82 is still located in the jack 22 and is limited by the jack 22, so that the ferrule holder 8 and the optical fiber adapter can still be located in a radially limited state. At this time, the optical fiber connector is rotated, so that the circular area formed by the guide ring 82 can limit the relative position of the ferrule holder 8, but the relative state between the ferrule holder 8 and the jack 22 can be adjusted, and the ferrule holder 8 can be inserted after the ferrule holder 8 and the jack 22 are completely right aligned, without multiple alignment.
The implementation principle of the embodiment of the application is as follows:
during the connection process, the insertion position of the ferrule holder 8 is first searched through the guiding structure at the end of the ferrule holder 8, at this time, the rotating outer sleeve 4 and the inner tube main body 3 synchronously rotate, and when the ferrule holder 8 is inserted into the insertion hole 22, the connecting block 41 is opposite to the connecting groove 21 and slides into the axial section 211 of the connecting groove 21 along with the pushing of the ferrule holder 8, so that the rapid blind mating and docking of the optical fiber connector and the optical fiber adapter are realized.
The slide 42 slides in the slide groove 32 to press the spring, and the rotary sleeve 4 rotates relative to the ferrule holder 8. To the corner of the connecting groove 21, the restoring force of the spring pushes the sliding sleeve to reversely slide along the sliding groove 32, and the sliding block 42 drives the rotating sleeve 4 to rotate for resetting, so that the connecting block 41 slides into the circumferential section 212 of the connecting groove 21 for axial limiting, thereby realizing self-locking of the optical fiber connector and the optical fiber adapter, and having high assembly efficiency.
When the optical fiber connector and the optical fiber adapter corresponding to the optical fiber connector are required to be detached, an operator only needs to rotate the rotating sleeve 4, so that the connecting block 41 slides to the corner 213 of the connecting groove 21, and the optical fiber connector can be pulled out of the optical fiber adapter axially, and the optical fiber connector is convenient to detach.
The embodiment of the application also discloses an optical fiber connector, which comprises an optical fiber connector and an optical fiber adapter connected with the optical fiber connector.
