As shown in fig. 7 to 9, when the male connector 1 and the female connector 2 are fixedly mated, the first ferrule 111 on the male connector 1 extends into the sleeve 21 of the female connector 2, and the second ferrule 231 on the female connector 2 is inserted from the other end of the sleeve 21 until it abuts against the first ferrule 111, so that the inserted fibers are butted and light is transmitted.
In order to fix the connector male head 1 and the connector female head 2 having a relatively small sectional area to each other, in the present embodiment, the end of the connector male head 1 is sleeved with a rotating head 31 capable of rotating freely, and the connector female head 2 is provided with a connecting head 32 in threaded fit with the rotating head 31, so that the connector female head 2 and the connector male head 1 can be fixed in threaded fit with the connecting head 32 through the rotating head 31, and the end of the first ferrule structure 11 is stable after being inserted into the sleeve 21.
This kind of mode through rotating head 31 and connector 32 screw-thread fit fixed can satisfy the less requirement of fiber connector sectional area, can firmly fix connector public head 1 and connector female head 2. In addition, since the rotator head 1 can rotate freely, the rotator head 31 will not twist the male connector 1 during the process of screwing the rotator head 31 and the connector 32, thereby preventing the optical fiber from being twisted and even twisted.
In this embodiment, the outer portion of the rotating head 31 is provided with external threads, and the inner portion of the connecting head 31 is provided with internal threads, so as to realize the matching of the two. Of course, the rotary head 31 may be provided on the female connector 2 and the connection head 31 may be provided on the male connector 1. In addition, the connector 32 may be fixed or integrally disposed on the male connector 1 or the female connector 2, and the integral disposing means that the connector 32 itself may not be an independent component, but a part (such as an end) of another component, and the fixedly disposed connector 32 is convenient for processing. However, the coupling head 32 may be freely rotatably provided so long as it can be connected with the rotary head 31 by screw-fitting.
In this embodiment, specifically, the first tail sleeve 113 is fixed at the tail of the first tail handle 112, the first tail sleeve 113 and the first tail handle 112 together form a groove, the rotating head 31 is sleeved on the groove, and the rotating head 31 can rotate freely and is limited in position in the axial direction. Of course, the first tail handle 112 may also be formed with other types of circumferential annular grooves, not necessarily with the first tail sleeve 113.
The connector female head 2 is provided with an outer frame sleeve 22, the sleeve 21 is positioned in the outer frame sleeve 22, a part of the end part of the first ferrule structure 11 is inserted into the outer frame sleeve 22 to form a matching, and the outer peripheral surface of the matching part of the first ferrule structure 11 and the outer frame sleeve 22 is formed by planes or cambered surfaces with different curvatures so as to limit the first ferrule structure 11 in the twisting direction. As shown in fig. 10, the cross section of the outer peripheral surface of the mating portion of the first ferrule structure 11 and the outer frame 22 is a racetrack shape, and the region where the outer frame 22 and the first ferrule structure 11 are mated is a kidney-shaped hole. This shape facilitates the machining of the outer frame 22 by milling with a milling cutter only at the location of the kidney-shaped hole. The outer frame 22 restricts the rotation of the first ferrule structure 11 by the stopper 222.
A part of the second ferrule structure 23 is fixed inside the outer sleeve 21, and an end of the second ferrule structure 23 is inserted into the sleeve 21 to abut against an end of the first ferrule structure 11 for optical transmission.

One end of the sleeve 21 close to the male connector 1 can abut against the side surface of the limiting protrusion 221 to prevent the sleeve 21 from coming off along the direction of the male connector 1.
In the present embodiment, the end of the outer frame 22 is a connection head 32, and the connection head 32 is a tubular structure with threads on the inner circumference, that is, the connection head 32 is a specific embodiment integrally disposed on the female connector 2.
The second ferrule structure 23 further includes a spring 235 and a fixing head 236 disposed along the axial direction, the fixing head 236 is fixed to the second tail sleeve 234, the tail end of the second tail handle 232 is inserted into the fixing head 236, and the spring 235 is sleeved on the tail end of the second tail handle 232. The fixing head 236 is fixed to the end of the outer frame 22, and thus the second tail 232 and the second ferrule 231 are pushed inward of the sleeve 21 by the elastic force of the spring, so that the second ferrule 231 and the first ferrule 111 can be held in abutment.
The traction type optical fiber connector further comprises a traction cap 12, the traction cap 12 can be covered on the end portion of the connector male head 1 and forms thread fixing, and a through hole is formed in the traction cap 12. The pulling rope in the perforation of the pulling cap 12 drives the male connector 1 to shuttle in the pipeline.
The pull-type optical fiber connector further comprises a dust cap 24, and the dust cap 24 can be covered on the end part of the connector female head 2. When the female connector 2 is not connected to the male connector 1, the dust cap 24 is used for dust prevention.
