[0002] The MPO connector is a type of fiber optic connector and is often used as a connector type for high-speed transmission standards. With the development of 5G communication, cloud computing, and big data, the integration degree of related data centers is getting higher and higher, and it is necessary to accommodate infinite data in a limited space. For this reason, the application of high-density MPO fiber optic connectors will be more and more.

[0003] In existing fiber optic communications, a large number of MPO connectors are used. When using the MPO connector, it is mainly plugged and unplugged by pinching the connector housing by hand. With the improvement of communication rate and capacity, the usage density of the connector is also getting higher and higher, and it is necessary to integrate and install more connectors in a limited space as much as possible. However, due to the requirements of the MPO connector standard, the physical shape cannot be infinitely reduced. As the installation density of the connector increases, the gap between the connectors on the device becomes smaller and smaller, and it is difficult for fingers to have enough space for plugging and unplugging operations. In order to achieve higher density usage, or plug and unplug in a relatively small space, a new technical solution is urgently needed to solve the plugging and unplugging usage in the case of high density and small space. Therefore, improving and innovating the above problems has become an urgent problem to be solved at present. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. For the MPO connector with a wire-pulling assisting function, through the provided housing body, inner bracket, ferrule body, guide pin body, mounting piece, tail sleeve body, upper opening, lower opening, lower slot, upper slot, first hook, connecting block, extension rod, wire-pulling assisting ring, fitting groove and abutting block, when it is necessary to pull out the ferrule body and the guide pin body, in the past, the housing body was directly grasped and pulled out. In this application, the first hook is installed inside the upper opening, and at the same time, the second hook is installed inside the lower opening. At this time, the first hook and the upper opening are mutually clamped and limited. Similarly, the second hook and the lower opening are also clamped and limited. When plugging and unplugging, by grasping the outer surface of the wire-pulling assisting ring, the wire-pulling assisting ring is fixedly installed integrally with the extension rod, the connecting block and the first hook. Thus, the wire-pulling assisting ring drives the movement of the housing body to achieve plugging and unplugging. Because the operation point is moved outwards through the wire-pulling assisting ring, the gap at the cable and the tail sleeve body will be increased. At the same time, the cable and the tail sleeve body are relatively soft and can be deformed to accommodate finger operation. Therefore, it can be operated and used in high-density and small-space situations. In this design, the housing body is extended through the extension rod. During use, by pulling the wire-pulling assisting ring, the movement of the housing body can be driven to achieve plugging and unplugging. The overall operation is relatively simple. Through the innovative structural design of this application, the MPO connector can be compatible with conventional use without increasing costs, and at the same time, the wire-pulling assisting function can be conveniently realized, supporting high-density and small-space use, and is convenient and flexible to use. This product is simple and flexible to use, not only compatible with traditional use, but also supports high-density and small-space use through the wire-pulling assisting structure, while taking cost control into account.

[0018] 2. The MPO connector with a function of facilitating extraction, through the set top block, top frame, grip frame, mounting bearing, screwing ring, side groove, first sliding groove, first slider, first moving plate, second sliding groove, second slider, second moving plate and first bearing block. Before use, the first hook needs to be installed inside the upper opening. Since the first hook needs to be pulled upward as a whole with the connecting block to adjust the angle when installed inside the upper opening, at this time, after the second hook enters the lower opening, the first hook and the connecting block are installed above the upper opening and the housing body. Then, by rotating the screwing ring, the connecting column can be driven to rotate by the screwing ring, and then the connecting column will drive the connecting rod to rotate, so that the connecting rod will drive the rotating gear to rotate. When the rotating gear rotates, since the rotating gear meshes with the first rack plate and the second rack plate, the moving directions of the first rack plate and the second rack plate are opposite. At this time, the first rack plate will drive the first slider to move backward, and then the second rack plate will drive the second moving plate to move forward. Thus, the first slider will drive the first bearing block to move, and similarly, the second moving plate will drive the second bearing block to move. Then, the first bearing block will move below the connecting block, and then the second bearing block will also move below the connecting block. Subsequently, the operator places the hand inside the side groove and presses the screwing ring with the palm at the same time to prevent the screwing ring from rotating, and then lifts the whole grip frame. Thus, the first hook and the connecting block will be adjusted at a certain angle, so that the first hook can be quickly placed inside the upper opening and clamped and limited with the housing body. The overall clamping effect is good. Therefore, this design can facilitate the installation of the first hook inside the upper opening, avoid the need for the operator to manually pull the first hook and the connecting block for operation in the past, speed up the installation rate, and reflect the functionality of the design.

A lower slot 9 is formed on the bottom surface of the inner wall of the housing body 1. An upper slot 10 is formed on the top surface of the inner wall of the housing body 1. The two structures of the upper opening 7, lower opening 8, lower slot 9, and upper slot 10 can be flexibly adjusted for symmetric, penetrating, or single-sided designs when applicable to different specifications of connectors;

[0036] The first hook 11 is installed inside the upper opening 7. A connecting block 12 is provided on the right surface of the first hook 11. A second hook is provided on the left surface of the connecting block 12 and is installed inside the lower opening 8. The right surface of the connecting block 12 is fixedly connected with an extension rod 13. A pulling aid ring 14 is provided on the right surface of the extension rod 13. An adaptation groove 15 is formed inside the connecting block 12 and is adapted to the tail sleeve body 6. Blocks 16 are installed on the upper and lower inner walls of the connecting block 12, and the left side of the block 16 abuts against the right surface of the housing body 1. A top block 17 is provided on the upper surface of the connecting block 12, and a top frame 18 is fixedly connected to the top surface of the top block 17. The extension rod 13 can be arranged left and right, up and down, or unidirectionally. The length of the extension rod 13 is adjusted by the length of the tail sleeve body 6. A grip frame 19 is fixedly connected to the top surface of the top frame 18. An installation bearing 20 is installed on the inner side wall of the grip frame 19. A screwing ring 21 is provided on the inner side wall of the installation bearing 20. Side grooves 22 are formed on the outer surface of the grip frame 19. A first sliding groove 23 and a second sliding groove 26 are sequentially formed on the surface of the top block 17 from front to back. A first sliding block 24 is arranged inside the first sliding groove 23, and a second sliding block 27 is arranged inside the second sliding groove 26. A first moving plate 25 is fixedly connected to the top surface of the first sliding block 24, and a second moving plate 28 is fixedly connected to the top surface of the second sliding block 27. A telescopic column 39 is fixedly connected to the back surface of the first sliding block 24. A spring body 37 is arranged on the outer surface of the telescopic column 39, and the spring body 37 is arranged inside an installation cylinder 36. The telescopic column 39 and the installation cylinder 36 are both installed inside the first sliding groove 23. A first bearing block 29 is fixedly connected to the lower surface of the first sliding block 24, and a second bearing block 30 is fixedly connected to the lower surface of the second moving plate 28. A rotating gear 31 is inserted and installed on the surface of the top block 17. A connecting rod 32 is fixedly connected to the top surface of the rotating gear 31. A connecting column 33 is fixedly connected to the top surface of the connecting rod 32, and the end of the connecting column 33 away from the connecting rod 32 is fixedly connected to the screwing ring 21. A first rack plate 34 is meshed and connected to the left surface of the rotating gear 31, and a second rack plate 35 is meshed and connected to the right surface of the rotating gear 31. The front end of the first rack plate 34 is connected to the back surface of the first sliding block 24, and the back surface of the second rack plate 35 is connected to the front end of the second moving plate 28. Installation grooves 38 are formed at the front and rear ends of the top frame 18, and the installation groove 38 at the front end of the top frame 18 is adapted to the first rack plate 34. When the first moving plate 25 moves, the first moving plate 25 will drive the first sliding block 24 to slide inside the first sliding groove 23, so that the overall sliding effect of the first moving plate 25 is relatively stable. At the same time, when the first sliding block 24 moves, it can drive the telescopic column 39 to move inside the installation cylinder 36, so that the telescopic column 39 can compress the spring body 37, so that the spring body 37 can be compressed. Thus, the moved first bearing block 29 is relatively stable. Subsequently, when the movement of the first bearing block 29 ends, at this time, the spring body 37 automatically rebounds, so that it can drive the telescopic column 39 to disengage from the inside of the installation cylinder 36.At this time, the telescopic column 39 will drive the first slider 24 to move, and then the first slider 24 will drive the first moving plate 25 to move forward. At this time, the first bearing block 29 will move away from the lower part of the connecting block 12. Similarly, the second bearing block 30 will also move away from the lower part of the connecting block 12. Thus, the overall use effect is good, and it will be immediately disengaged from the connecting block 12 after the operation is completed. When it is necessary to pull out the ferrule body 3 and the guide pin body 4, in the past, it was directly pulled out by holding the outer shell body 1. In this application, the first hook 11 is installed inside the upper opening 7, and at the same time, the second hook is installed inside the lower opening 8. At this time, the first hook 11 and the upper opening 7 are mutually clamped and limited. Similarly, the second hook and the lower opening 8 are also clamped and limited. When performing plugging and unplugging, by holding the outer surface of the assisting pulling ring 14, the assisting pulling ring 14 is fixedly installed with the extension rod 13, the connecting block 12 and the first hook 11 as a whole. Thus, the assisting pulling ring 14 will drive the movement of the outer shell body 1 to achieve plugging and unplugging. Because the operation point is moved outwards by the assisting pulling ring 14, the gap at the cable and the tail sleeve body 6 will increase. At the same time, the cable and the tail sleeve body 6 are relatively soft and can be deformed to accommodate finger operation. Therefore, it can be operated and used even in high-density and small-space environments. In this design, the outer shell body 1 is extended by the extension rod 13. During use, by pulling the assisting pulling ring 14, the movement of the outer shell body 1 can be driven to achieve plugging and unplugging. It is necessary to install the first hook 11 inside the upper opening 7. Since the first hook 11 needs to be pulled upwards as a whole with the connecting block 12 to adjust the angle when installed inside the upper opening 7, when the second hook enters the lower opening 8, at this time, the first hook 11 and the connecting block 12 are installed above the upper opening 7 and the outer shell body 1. Then, by rotating the screwing ring 21, the connecting column 33 can be driven to rotate by the screwing ring 21. Then, the connecting column 33 will drive the connecting rod 32 to rotate. Thus, the connecting rod 32 will drive the rotating gear 31 to rotate. When the rotating gear 31 rotates, since the rotating gear 31 meshes with the first rack plate 34 and the second rack plate 35, the moving directions of the first rack plate 34 and the second rack plate 35 are opposite. At this time, the first rack plate 34 will drive the first slider 24 to move towards the back, and then the second rack plate 35 will drive the second moving plate 28 to move forward. Thus, the first slider 24 will drive the first bearing block 29 to move. Similarly, the second moving plate 28 will drive the second bearing block 30 to move. Then, the first bearing block 29 will move to the lower part of the connecting block 12, and then the second bearing block 30 will also move to the lower part of the connecting block 12. Subsequently, the operator places the hand inside the side groove 22, and at the same time presses the screwing ring 21 with the palm to prevent the screwing ring 21 from rotating. Then, the whole holding frame 19 is lifted. Thus, the first hook 11 and the connecting block 12 will be adjusted at a certain angle, so that the first hook 11 can be quickly placed inside the upper opening 7 and clamped and limited with the outer shell body 1. The overall clamping effect is good.Therefore, this design can facilitate the installation of the first hook 11 into the upper opening 7, avoiding the need for operators to manually move the first hook 11 and the connecting block 12 in the past, and accelerating the installation rate.

[0037] Working principle: When in use, when it is necessary to pull out the ferrule body 3 and the guide pin body 4, in the past, the outer shell body 1 was directly grasped and pulled out. In this application, by installing the first hook 11 into the upper opening 7, and at the same time, the second hook will be installed into the lower opening 8. At this time, the first hook 11 and the upper opening 7 are mutually clamped and limited. Similarly, the second hook and the lower opening 8 are also clamped and limited. When performing plugging and unplugging, by grasping the outer surface of the auxiliary pulling ring 14, the auxiliary pulling ring 14 is fixedly installed with the extension rod 13, the connecting block 12 and the first hook 11 as a whole. Therefore, the auxiliary pulling ring 14 will drive the movement of the outer shell body 1 to achieve plugging and unplugging. Because the operation point is moved outwards through the auxiliary pulling ring 14, the gap at the cable and the tail sleeve body 6 will increase. At the same time, the cable and the tail sleeve body 6 are relatively soft and can be deformed to accommodate finger operation. Therefore, it can be operated and used even in high-density and small-space environments. The outer shell body 1 is extended through the extension rod 13. During use, by pulling the auxiliary pulling ring 14, the movement of the outer shell body 1 can be driven to achieve plugging and unplugging.

[0038] Install the first hook 11 inside the upper opening 7. When installing the first hook 11 inside the upper opening 7, it is necessary to lift the first hook 11 and the connecting block 12 as a whole to adjust the angle. At this time, after the second hook enters the inside of the lower opening 8, the first hook 11 and the connecting block 12 are installed above the upper opening 7 and the housing body 1. Then, by rotating the screwing ring 21, the connecting column 33 can be driven to rotate by the screwing ring 21. Then, the connecting column 33 will drive the connecting rod 32 to rotate, so that the connecting rod 32 will drive the rotating gear 31 to rotate. When the rotating gear 31 rotates, since the rotating gear 31 meshes with the first rack plate 34 and the second rack plate 35, the moving directions of the first rack plate 34 and the second rack plate 35 are opposite. At this time, the first rack plate 34 will drive the first slider 24 to move backward, and then the second rack plate 35 will drive the second moving plate 28 to move forward. Thus, the first slider 24 will drive the first bearing block 29 to move. Similarly, the second moving plate 28 will drive the second bearing block 30 to move. Then, the first bearing block 29 will move to the lower part of the connecting block 12, and then the second bearing block 30 will also move to the lower part of the connecting block 12. Subsequently, the operator places the hand inside the side groove 22 and presses the screwing ring 21 with the palm at the same time to prevent the screwing ring 21 from rotating. Then, the whole holding frame 19 can be lifted. Thus, the first hook 11 and the connecting block 12 will be adjusted by a certain angle, so that the first hook 11 can be quickly placed inside the upper opening 7 and clamped and limited with the housing body 1. When the first moving plate 25 moves, the first moving plate 25 will drive the first slider 24 to slide inside the first chute 23. Thus, the overall sliding effect of the first moving plate 25 is relatively stable. At the same time, when the first slider 24 moves, it can drive the telescopic column 39 to move inside the mounting cylinder 36. Thus, the telescopic column 39 can compress the spring body 37. Thus, the spring body 37 can be compressed. Thus, the moved first bearing block 29 is relatively stable. Subsequently, when the movement of the first bearing block 29 ends, the spring body 37 automatically rebounds. Thus, it can drive the telescopic column 39 to disengage from the inside of the mounting cylinder 36. At this time, the telescopic column 39 will drive the first slider 24 to move, and then the first slider 24 will drive the first moving plate 25 to move forward. At this time, the first bearing block 29 will move away from the lower part of the connecting block 12. Similarly, the second bearing block 30 will also move away from the lower part of the connecting block 12. The above is all the working principles of the present invention.

[0039] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention; any ordinary technician in the industry can smoothly implement the present invention according to what is shown in the accompanying drawings of the specification and the above; however, any minor changes, modifications, and equivalent variations made by those skilled in the art within the scope of the technical solution of the present invention by using the technical content disclosed above are all equivalent embodiments of the present invention; at the same time, any changes, modifications, and equivalent variations made to the above embodiments based on the substantial technology of the present invention still fall within the protection scope of the technical solution of the present invention.
