Description

Technical Field

[0001] This utility model relates to the field of optical fiber communication technology, and in particular to connectors. Background Technology

[0002] 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.

[0003] Depending on the usage requirements, the two optical fibers may need to be connected or disconnected. Existing connectors typically include a handle that connects to the connector body; applying force to the handle connects the two optical fibers or unlocks and disconnects them.

[0004] The shortcomings of existing 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.

[0038] This embodiment discloses a connector for connecting cables such as optical fibers together. Figure 1 and Figure 2 As shown, the connector includes a connector body, a handle 1, and a tail sleeve 2 for threading cables. 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.

[0039] Pull handle 1 and tail sleeve 2 work together. When tail sleeve 2 moves away from the connector body, it pulls pull handle 1, which unlocks the connector body. When tail sleeve 2 moves towards the connector body, it pushes the connector body to insert the adapter. By combining the previously independent pull handle 1 and tail sleeve 2, the overall connector structure becomes more compact without affecting normal connection and disconnection. This allows for smooth insertion and removal of the connector even in confined spaces, making it more convenient and applicable to a wider range of situations.

[0040] The specific method for achieving "the tail sleeve 2 can drive the handle 1 to move away from the connector body" is not limited. 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.

[0041] To prevent the tail sleeve 2 from coming off the handle 1 when pulling, such as Figures 3 to 5As shown, the handle 1 includes a ring-shaped handle body 11, and a handle anti-reverse boss 12 is provided inside the handle body 11; a tail sleeve 2 is provided with a tail sleeve protrusion 21 at one end, 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.

[0042] 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.

[0043] In order to achieve the detachable connection between the tail sleeve 2 and the handle 1, the handle 1 can only block the relative movement of the tail sleeve 2 when the tail sleeve 2 is pulled backward; 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.

[0044] Therefore, when "tail sleeve 2 moves towards the connector body", other structures are needed to "push the connector body to move". In this embodiment, such as... Figure 2 , Figure 4 and Figure 6 As shown, when the tail sleeve 2 moves toward the connector body, the tail sleeve protrusion 21 abuts against the base 3, thereby pushing the connector body forward until it is inserted into the adapter. It is easy to use, occupies little space, and requires little effort to insert or remove.

[0045] Based on the above structure, such as Figures 2 to 4 , Figure 7 As shown, the handle 1 includes a handle back plate 14 connected to the handle body 11, and the handle back plate 14 has 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.

[0046] 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.

[0047] The specific structure supporting the rotation of the cover plate 5 is not limited. 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.

[0048] 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.

[0049] 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.

[0050] Based on the above structure, such as Figure 2 , Figures 8 to 10 As shown, 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, it prevents the stop ring 6 from rotating around its axis; when the anti-rotation protrusion 71 is removed from the anti-rotation groove 61, the stop ring 6 can rotate around its axis. It can be understood that the specific shape and structure of the anti-rotation protrusion 71 are not limited, as long as it can be inserted into and removed from the anti-rotation groove 61.

[0051] 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.

[0052] The specific structure of the T-shaped anti-rotation ridge 72 is not limited. 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.

[0053] Based on the above structure, such as Figure 2 , Figure 6 , Figure 11 and Figure 12 As shown, 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. The outer frame 7 forms a mounting cavity 74 with openings at both ends. The stop ring 6, base 3, and top cover 8 are assembled and placed in the mounting 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.

[0054] 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.

[0055] 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.

[0056] When disassembly is required, the user holds the outer frame 7 with one hand and pushes the tail sleeve 2 with the other hand. The tail sleeve 2 presses against the base 3 and moves away from the outer frame 7. Until the anti-rotation ridge 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 integral 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°.

[0057] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention. The scope of the present invention is determined by the scope of the appended claims.
