[0001] This application claims priority to Chinese Patent Application No. 202520538856.8, filed with the Chinese Patent Office on March 25, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of optical fiber communication technology, and for example to a connector. Background Technology

[0003] The connector can detachably connect two optical fibers together, specifically by mating the end face of the transmitting fiber to the end face of the receiving fiber, so that the light energy output from the transmitting fiber can be coupled into the receiving fiber to the maximum extent.

[0004] Depending on the application, the two optical fibers may need to be connected or disconnected. A typical connector usually includes a handle that connects to the connector body; applying force to the handle connects the two optical fibers or disconnects them.

[0005] The drawbacks of conventional connectors include: the handle is a separate structure located on the side of the tail sleeve, which takes up some space and limits the scope of application of the connector; in confined spaces (such as in high-density environments such as data centers), it is difficult for users to apply pushing or pulling force to the handle, making it difficult to connect or disconnect the fiber optic cable, resulting in inconvenience in use. Summary of the Invention

[0006] This application proposes a connector that solves the problem of inconvenience in using conventional connectors and has a wide range of applications.

[0007] This application discloses a connector, comprising: a connector body; a handle connected to the connector body; and a tail sleeve configured to carry a cable; wherein when the tail sleeve moves away from the connector body, it can pull the handle to unlock the connector body; and when the tail sleeve moves toward the connector body, it can push the connector body to move.

[0008] In some embodiments, one end of the tail sleeve passes through the handle, and when the tail sleeve moves away from the connector body, the end of the tail sleeve abuts against the inner wall of the handle.

[0009] In some embodiments, the handle includes an annular handle body, and a handle anti-reverse boss is provided inside the handle body; a tail sleeve protrusion is provided on one end of the tail sleeve, and when the tail sleeve moves away from the connector body, the tail sleeve protrusion abuts against the handle anti-reverse boss.

[0010] In some embodiments, the handle body has a notch, and the tail sleeve has a tail sleeve limiting member located in the notch.

[0011] In some embodiments, the connector body includes a base, and when the tail sleeve moves toward the connector body, the tail sleeve protrusion abuts against the base.

[0012] In some embodiments, the connector body further includes a connector handle and a cover plate. When the tail sleeve pulls the handle in a direction away from the connector body, the handle can drive the cover plate to rotate. After the cover plate rotates, it can press the connector handle to unlock the connector body.

[0013] In some embodiments, the connector body further includes a stop ring and an outer frame, one of which is provided with an anti-rotation groove, and the other of which is provided with an anti-rotation protrusion, the anti-rotation protrusion being able to insert into and exit the anti-rotation groove.

[0014] In some embodiments, the anti-rotation grooves are respectively provided on opposite sides of the stop ring, and the anti-rotation protrusions and T-shaped anti-rotation ridges are respectively provided on the outer frame to match the anti-rotation grooves.

[0015] In some embodiments, the T-shaped anti-rotation ridge includes a connected ridge body and a limiting ridge bottom, with a height difference between the ridge body and the limiting ridge bottom, and the ridge body can be inserted into and removed from the anti-rotation groove.

[0016] In some embodiments, the connector body includes a base and a top cover, the stop ring is located in the cavity between the base and the top cover, the base and the top cover are respectively provided with through holes, and the anti-rotation groove is located in the through holes.

[0036] This embodiment discloses a connector for connecting cables such as optical fibers together. As shown in Figures 1 and 2, the connector includes a connector body, a handle 1, and a tail sleeve 2 for threading cables through it. The handle 1 is connected to the connector body. The connector body includes a base 3, a connector push handle 4, a cover plate 5, a stop ring 6, an outer frame 7, and a top cover 8.

[0037] Pull handle 1 and tail sleeve 2 work together. When tail sleeve 2 moves away from the connector body, it pulls pull handle 1, unlocking the connector body. When tail sleeve 2 moves towards the connector body, it pushes the connector body to insert the adapter. By using pull handle 1 and tail sleeve 2, which are usually independent, together, the overall structure of the connector is more compact without affecting the normal connection and disconnection of the connector. This allows for smooth insertion and removal of the connector even in relatively small spaces, making it more convenient to use and expanding its application range.

[0038] In this embodiment, one end of the tail sleeve 2 is inserted into the handle 1. When the tail sleeve 2 moves away from the connector body, the end of the tail sleeve 2 abuts against the inner wall of the handle 1. That is, the tail sleeve 2 and the handle 1 form a nested structure. Pulling the tail sleeve 2 can drive the handle 1 to move synchronously, thereby unlocking the connector. The shapes of the tail sleeve 2 and the handle 1 are more reasonable, easier to process, and occupy less space. In other embodiments, the "tail sleeve 2 can drive the handle 1 to move away from the connector body" can also be achieved by other methods.

[0039] To prevent the tail sleeve 2 from coming off the handle 1 when it is pulled, as shown in Figures 3 to 5, the handle 1 includes an annular handle body 11, and the handle body 11 is provided with a handle anti-reverse boss 12 inside; a tail sleeve protrusion 21 is provided on one end of the tail sleeve 2, and when the tail sleeve 2 moves away from the connector body, the tail sleeve protrusion 21 abuts against the handle anti-reverse boss 12.

[0040] Since the nested structure formed by the tail sleeve 2 and the handle 1 cannot prevent the tail sleeve 2 from rotating relative to the handle 1 around the axis, in this embodiment, a notch 13 is provided on the handle body 11, and a tail sleeve limiting member 22 is provided on the tail sleeve 2. The tail sleeve limiting member 22 is located in the notch 13, and the tail sleeve 2 and the handle 1 are relatively fixed in the circumferential direction, so that the tail sleeve 2 and the handle 1 cannot rotate relative to each other around the axis, making it safer to use.

[0041] Tail sleeve 2 and handle 1 are detachably connected: when the tail sleeve 2 is pulled backward, the handle 1 can block the relative movement of the tail sleeve 2; when the tail sleeve 2 is pushed forward, the handle 1 does not block the sliding of the tail sleeve 2, allowing the tail sleeve 2 to be pulled out from the front end of the handle 1.

[0042] When the tail sleeve 2 moves toward the connector body, other structures are needed to "push the connector body to move". In this embodiment, as shown in Figures 2, 4 and 6, when the tail sleeve 2 moves toward the connector body, the tail sleeve protrusion 21 can abut against the base 3, thereby pushing the connector body forward until it is inserted into the adapter. It is convenient to use, occupies little space, and requires little effort to insert and remove.

[0043] In some embodiments, as shown in Figures 2 to 4 and Figure 7, the handle 1 includes a handle back plate 14 connected to the handle body 11, and the handle back plate 14 is provided with an unlocking through hole 16; the cover plate 5 is provided with two hinge shafts 51, and the two ends of the cover plate 5 are respectively provided with an unlocking inclined surface 52 and an unlocking pressing surface 53, and the unlocking inclined surface 52 passes through the unlocking through hole 16.

[0044] When the tail sleeve 2 pulls the handle 1 away from the connector body, the unlocking through hole 16 moves relative to the unlocking inclined surface 52. The edge of the unlocking through hole 16 pushes the inclined surface of the unlocking inclined surface 52, allowing the cover plate 5 to swing around the hinge axis 51. After the cover plate 5 swings to a set angle, the unlocking pressing part 53 presses the connector button 4, thereby unlocking the connector body and pulling the connector out of the adapter.

[0045] The specific structure supporting the rotation of the cover plate 5 can be configured according to actual conditions. In this embodiment, the outer frame 7 is provided with two hinge holes 75, and each hinge shaft 51 passes through the corresponding hinge hole 75. When the edge of the unlocking through hole 16 pushes against the inclined surface of the unlocking inclined piece 52, the cover plate 5 can rotate around the hinge shaft 51. The overall structure is simple and reasonable. By adjusting the distance between the unlocking pressing piece 53 and the hinge shaft 51, the force of pressing the connector handle 4 can be increased or decreased, making it more convenient to use.

[0046] To make the connection structure between the handle 1 and the outer frame 7 more stable, a long strip-shaped guide hole 15 is provided on the handle back plate 14, and a guide member 76 is provided on the outer frame 7. The guide member 76 is located in the guide hole 15 and can move along the extension direction of the guide hole 15, thereby allowing the handle 1 to move a certain distance relative to the outer frame 7 to drive the cover plate 5 to swing.

[0047] In addition, the handle body 11 is provided with a hook 17, and the outer frame 7 is provided with a hook engagement hole 73. After installation, the hook 17 is fastened in the hook engagement hole 73, realizing a stable connection between the handle 1 and the outer frame 7. In order to leave room for relative movement of the handle 1, the hook engagement hole 73 is elongated, and the hook 17 can move in the hook engagement hole 73.

[0048] In some embodiments, as shown in Figures 2, 8 to 10, one of the stop ring 6 and the outer frame 7 is provided with an anti-rotation groove 61, and the other of the stop ring 6 and the outer frame 7 is provided with an anti-rotation protrusion 71. When the anti-rotation protrusion 71 can be inserted into the anti-rotation groove 61, the stop ring 6 cannot rotate around the axis; when the anti-rotation protrusion 71 is removed from the anti-rotation groove 61, the stop ring 6 can rotate around the axis. The specific shape and structure of the anti-rotation protrusion 71 can be set according to the actual situation, as long as it can be inserted into and removed from the anti-rotation groove 61.

[0049] To ensure more even force distribution on the stop ring 6, in this embodiment, anti-rotation grooves 61 are provided on opposite sides of the stop ring 6. Correspondingly, the outer frame 7 is provided with anti-rotation protrusions 71 and T-shaped anti-rotation ribs 72. The anti-rotation protrusions 71 are adapted to the anti-rotation grooves 61 on one surface, and the T-shaped anti-rotation ribs 72 are adapted to the anti-rotation grooves 61 on the other surface. The anti-rotation protrusions 71 and T-shaped anti-rotation ribs 72 restrict the stop ring 6 from opposite sides, thus better preventing the stop ring 6 from rotating around its axis.

[0050] The specific structure of the T-shaped anti-rotation ridge 72 can be configured according to actual conditions. In this embodiment, the T-shaped anti-rotation ridge 72 includes a connected ridge body 721 and a limiting ridge bottom 722, with a height difference between the ridge body 721 and the limiting ridge bottom 722. The ridge body 721 can be inserted into and withdrawn from the anti-rotation groove 61, and the limiting ridge bottom 722 can abut against the edge of the anti-rotation groove 61, preventing the ridge body 721 from being inserted too much into the anti-rotation groove 61, thus making the relative position of the stop ring 6 and the outer frame 7 more accurate.

[0051] In some embodiments, as shown in Figures 2, 6, 11, and 12, the stop ring 6 is located in the cavity between the base 3 and the top cover 8. The stop ring 6 can rotate freely, facilitating polarity changes. An installation cavity 74 with openings at both ends is formed inside the outer frame 7. The stop ring 6, base 3, and top cover 8 are assembled and placed in the installation cavity 74. The top cover 8 has a top cover through hole 81, and an anti-rotation groove 61 on one side is located in the top cover through hole 81. The base 3 has a base through hole 31, and an anti-rotation groove 61 on the other side is located in the base through hole 31, without affecting the insertion and withdrawal of the anti-rotation protrusion 71 and the T-shaped anti-rotation ridge 72 into and out of the anti-rotation groove 61, respectively.

[0052] The top cover 8 is provided with a T-shaped exit groove 82. The anti-rotation protrusion 71 or the T-shaped anti-rotation ridge 72 can enter the exit groove 82 to realize the assembly and snap-fit ​​of the stop ring 6, the base 3, the top cover 8 and the outer frame 7, making the assembly structure more stable.

[0053] During installation, the integral structure consisting of the stop ring 6, base 3, and top cover 8 is inserted into the mounting cavity 74 of the outer frame 7. The anti-rotation protrusion 71 or T-shaped anti-rotation ridge 72 abuts against the edge of the exit groove 82. With continued force, the anti-rotation protrusion 71, T-shaped anti-rotation ridge 72, or exit groove 82 will undergo a certain degree of elastic deformation. After the anti-rotation protrusion 71 or T-shaped anti-rotation ridge 72 passes over the top of the edge of the exit groove 82, it falls into the exit groove 82, which can prevent the integral structure consisting of the stop ring 6, base 3, and top cover 8 from coming out of the outer frame 7.

[0054] When it is necessary to disassemble the outer frame 7, the user holds the outer frame 7 with one hand and pushes the tail sleeve 2 with the other hand. The tail sleeve 2 pushes against the base 3 and moves forward until the anti-rotation protrusion 71 or the T-shaped anti-rotation ridge 72 passes the top of the edge of the exit groove 82 and leaves the exit groove 82. The whole structure consisting of the stop ring 6, the base 3 and the top cover 8 is pushed out of the outer frame 7, and then the connector can be rotated 180°.
