As shown in FIG. 3, the optical fiber connector comprises a connector body 1, an outer enclosure 2, and a handle 3. The connector body 1 can be connected to an adapter and latched therein. The connector body 1 is provided with a head 11 configured to be connected to another optical fiber connector. After inserting the connector body 1 into the adapter, the heads 11 on the connector bodies 1 at both ends of the adapter are precisely connected to each other via a sleeve in the housing. 'adapter. The connector body 1 comprises an inner enclosure 13, a rear enclosure 14 and a rear sleeve 15 connected sequentially. The head 11 is disposed on the inner enclosure 13. The rear sleeve 15 is configured for the passage of an optical fiber connection wire. The rear enclosure 14 protrudes from the inner enclosure 13. The outer enclosure 2 is configured to enclose the connector body 1 and to slide along the connector body 1. When the outer enclosure 2 slides toward the outside, the connector body 1 can be unlocked from the adapter and removed from it. The handle 3 comprises a support portion 31 and an attachment portion 32. The attachment portion 32 extends forwardly from the support portion 31. The support portion 31 facilitates the pushing action and pulling the handle 3. The support portion 31 is provided with a non-slip pattern.
    In this embodiment, a first sliding slot 12 is disposed outside of the connector body 1. Here, the first sliding slot 12 is a through hole and the first sliding slot 12 is an open through hole on the outside. rear enclosure 14. The attachment portion 32 passes through the first sliding slot 12 and slides along the first sliding slot 12. The cooperation between the attachment portion 32 and the first sliding slot 12 provides sliding reliability and connection between the handle 3 and the connector body 1. The connector body 1 and the handle 3 are each provided with a stop portion. As the handle 3 moves forward along the first sliding slot 12, the handle 3 abuts against the connector body 1 through the stop portions to push the connector body 1 forward. In this embodiment, the attachment portion 32 extends forwardly from an end face of the support portion 31, and the end face of the support portion 31 and an end face. rear of the rear enclosure 14 are each provided with a stop portion. When the handle 3 slides forward along the first sliding slot 12, the end face of the support portion 31 abuts against the rear end face of the rear enclosure 14. In this embodiment based on an arrangement direction of the rear sleeve 15, the rear enclosure 14 and the inner enclosure 13, the direction from the rear sleeve 15 to the inner enclosure 13 is the forward direction and the direction from the inner enclosure 13 to the rear sleeve 15 is the rearward direction.
    When the handle 3 moves backwards along the first sliding slot 12, the attachment portion 32 may be hooked on the outer enclosure 2 to pull the outer enclosure 2 rearwardly.
    The handle 3 in this embodiment pushes the connector body 1 forward by the stop portions, facilitating the insertion of the connector body 1 into the adapter. The attachment of the attachment portion 32 on the outer enclosure 2 allows the handle 3 to pull back the outer enclosure 2 to unlock the connector body 1 from the adapter. In comparison with the art in which a handle is disposed outside of a connector body 1 by wrapping the connector body, the handle in this embodiment no longer needs to wrap the connector body 1 from the outside. The handle 3 is slidably connected to the connector body 3 reliably simply by making the first sliding slot 12 cooperate with the hooking part 32 and by passing the hooking part 32 through the first sliding slot 12, simplifying the structure of the handle 3, reducing the manufacturing costs of the handle 3 and reducing the overall dimension of the optical fiber connector.
    Due to the use of a structure in which the first sliding slot 12 cooperates with the attachment portion 32, the handle 3 no longer needs to wrap the connector body 1 from the outside. Thus, the handle 3 may be a plate structure. The flat design of the plate structure simplifies the structure of the handle 3, reduces the manufacturing costs of the handle 3. In addition, the structural strength of the plate structure is high.
    In this embodiment, the rear enclosure 14 protrudes from the inner enclosure 13 and the first sliding slot 12 is a through hole on the rear enclosure 14. Line such structure makes it easy to limit the position of the attachment portion 32 and provides stability of the connection between the handle 3 and the connector body 1. Line such structure involves a small modification relative to the original connector body. The first sliding slot 12 may be disposed on the rear enclosure 14 or disposed on the inner enclosure 13 or the rear sleeve 15, as long as the hooking portion 32 can slide reliably along the first sliding slot 12 of in order to bring the handle 3 to be slidably connected to the connector body 1 reliably.
    In this embodiment, the support portion 31 passes through the first sliding slot 12 disposed on the rear enclosure 14, if simply by causing the end face of the support portion 31 to abut against the face rear end of the rear enclosure 14, it is possible to push the connector body 1 forward, not requiring additional stop portions and thus simplifying the overall structure and ensuring usability for the user . Of course, additional abutment portions may be disposed on the connector body 1 and the handle 3. For example, a first abutment portion may protrude from a surface of the support portion 31 adjacent to the connector body 1, and a second abutment portion may be disposed on the rear sleeve 15 or the rear enclosure 14. The first abutment portion and the second abutment portion may abut against each other. Alternatively, abutting abutting portions against each other may be provided on the engaging portion 32 and the inner housing 13. In short, this is possible so long as the abutment portions can be used to push the connector body 1 forward when the handle 3 is pushed forward.
    As shown in FIG. 4, in this embodiment, the attachment portion 32 comprises an elastic arm 321 extending forwardly from the support portion 31 and a hook 322 projecting from the elastic arm 321. The elastic arm 321 can slide along the first sliding slot 12, and the hook 322 can be hooked on the outer enclosure 2 to pull the outer enclosure 2 backwards. The bending of the elastic arm 321 allows the hook 322 to penetrate into an attachment zone of the outer enclosure 2. The resilience of the elastic arm 321 reliably hooks the hook 322 on the outer enclosure 2.
    To prevent the hook 322 from leaving the outer enclosure 2, a projecting portion 324 is formed at a position of the elastic arm 321 next to the support portion 31, and the first sliding slot 12 is provided with a recessed portion 325 tightly fitting the protruding portion 324. The protruding portion 324 not only improves the structural strength of an area of the resilient arm 321 adjacent to the support portion 31 and improves the rigidity of the resilient arm 321, but adjusts also closely the recessed portion 325 to prevent the resilient arm 321 from shaking in the first sliding slot 12. All of these elements improve the reliable hooking of the hook 322. The projecting portion 324 is disposed adjacent the support portion 31 to avoid the impact when a front end of the elastic arm 321 slides.
    To facilitate the attachment of the hook 322, the outer enclosure 2 is provided with a second sliding slot 21 extending in the same direction as the first sliding slot 12, a stop arm 22 is arranged at the of the second sliding slot 21, and the hook 322 is hooked on the stop arm 22 by resilience of the elastic arm 321 after the passage of the hook 322 through the second sliding slot 21. A tongue-like structure is formed by the arm 221 and the hook 322. The elastic arm 321 ensures that the hook 322 is reliably hooked onto one end face of the stop arm 22. The second sliding slot 21 can further limit the position of the elastic arm 321 to ensure that the elastic arm 321 and the hook 322 slide along the second sliding slot 21 and are accurately hooked on the stop arm 22. The second sliding slot 21 cooperates with the first neck slot. smoothing 12 to further limit the position of the handle 3 which slides so as to ensure that the handle 3 slides in a predetermined direction.
    In this embodiment, the stop arm 22 is located on a rear end of the second sliding slot 21 and is connected to two sides of the second sliding slot 21 to improve the structural strength of the stop arm 22. In one or more embodiments, the stop arm 22 is formed protruding from one side of the second sliding slot 21. Such a stop arm must have a high strength to avoid being damaged when is pulled.
    To facilitate the introduction of the hook 322 into the second sliding slot 21 and avoid the stop arm 22, the hook 322 is provided with a guide portion 323 for guiding the hook 322 in the second sliding slot 21 , and the guide portion 323 is inclined in an extension direction of the second sliding slot 21.
    In this embodiment, two side-by-side hooking parts 32 are arranged on a front end of the support portion 31 to pull the outer enclosure 2 from two sides, so that each attachment portion 32 carries a reduced tensile force, balancing the force on two sides of the outer enclosure 2. Of course, the number of attachment portions 32 can be defined according to actual needs. For example, additional hooking portions may be disposed on the opposite side.
    The foregoing merely constitutes embodiments of the present description. Those skilled in the art will make modifications to the embodiments and scope of the application according to the present disclosure. The contents of this specification should not be construed as limiting this description.
