Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-6This utility model provides a high-density transmission MPO adapter technical solution: it includes a main body 1, which includes an upper connector 2, a lower connector 3, and a fixed frame 4. The upper connector 2 is fixedly installed at one end of the fixed frame 4, and the lower connector 3 is connected to the other end of the fixed frame 4 through a rotating connection structure. Both the upper connector 2 and the lower connector 3 are provided with dual-position insertion holes 6. An upper insertion terminal 7 is inserted into the upper connector 2 through the dual-position insertion hole 6, and a lower insertion terminal 8 is inserted into the lower connector 3 through the dual-position insertion hole 6. Both the upper connector 2 and the lower connector 3 are provided with two sets, and the lower connector 3 and the lower connector 3 are connected to each other through the dual-position insertion hole 6. Fixing components and limiting components are provided between the upper connector 2 and the upper insertion terminal 7, and between the lower connector 3 and the lower insertion terminal 8.

[0020] Combination Figure 2 As shown, the rotating connection structure includes a limiting post 9, a limiting block 10, and a mounting hole 11. The limiting post 9 is fixedly installed at the middle position of one end of the fixed frame 4. The mounting hole 11 is opened on one end surface of the lower connector 3, and one end of the limiting post 9 is rotatably connected in the mounting hole 11. The limiting block 10 is fixedly installed on both sides of the lower surface of the fixed frame 4. The top surface of the lower connector 3 has slots 14 on both sides that cooperate with the limiting block 10. The limiting block 10 can limit the rotation angle of the lower connector 3 to prevent the lower connector 3 from rotating excessively and affecting the docking effect with the upper connector 2. After the lower connector 3 rotates to the correct position relative to the fixed frame 4 each time, the limiting block 10 can accurately engage in the slot 14, thereby achieving stable fixation of the lower connector 3 on the fixed frame 4. That is, the lower connector 3 and the fixed frame 4 form a stable positioning connection through the cooperation of the limiting block 10 and the slot 14.

[0021] A compression spring 12 is fitted onto the limiting post 9, and a stop 13 is fixedly installed at one end of the limiting post 9. The compression spring 12 is limited between the stop 13 and the inner wall of the mounting hole 11. By setting the compression spring 12, it can be reset after the lower connector 3 rotates, thereby facilitating the docking of the lower connector 3 with the upper connector 2. At the same time, the stop 13 can prevent the limiting post 9 from disengaging in the mounting hole 11, improving the stability of the overall structure.

[0022] During use, when it is necessary to connect the lower connector 3 and the upper connector 2, simply rotate the lower connector 3 to align the dual-position plug holes 6, and then insert the corresponding plug terminals to complete the connection. The operation is convenient and quick.

[0023] Combination Figure 4 As shown, the fixing component includes a snap-on plate 15 located on both sides of the dual-position insertion hole 6. A snap-on block 16 is fixedly installed on the snap-on plate 15. The upper insertion terminal 7 and the lower insertion terminal 8 are fixed by the snap-on engagement of the snap-on block 16.

[0024] Combination Figure 4 As shown, the limiting component includes an outer limiting groove 17, a side limiting groove 18, and an inner limiting groove 19. The outer limiting groove 17 is located at the opening of the dual-station insertion hole 6, the side limiting groove 18 is located on one side of the outer limiting groove 17, and the inner limiting groove 19 is located on the inner wall of the dual-station insertion hole 6.

[0025] Combination Figure 3 As shown, both the upper connector 2 and the lower connector 3 are provided with a first limiting part 25, a second limiting part 21, and a third limiting part 5. The first limiting part 25, the second limiting part 21, and the third limiting part 5 are adapted to the shape and size of the outer limiting groove 17, the side limiting groove 18, and the inner limiting groove 19, respectively. The setting of the first limiting part 25, the second limiting part 21, and the third limiting part 5 ensures that the upper connector 2 and the lower connector 3 can be accurately and stably positioned when inserted into the dual-position insertion hole 6, which not only improves the stability of the connection, but also effectively prevents the connector from loosening or falling off during use.

[0026] The combination of various limiting slots and limiting parts ensures the stability and accuracy of the fiber optic connector after insertion. The outer limiting slot 17 serves as an initial limit to prevent the fiber optic connector from deviating from the predetermined trajectory during insertion. The side limiting slot 18 further restricts the movement range of the fiber optic connector, increasing its stability. The inner limiting slot 19 serves as the final limit to ensure the precise docking of the fiber optic connector with the dual-position jack 6, thereby improving the stability and efficiency of data transmission.

[0027] Combination Figure 5 As shown, in this embodiment, elastic retaining plates 24 are provided on both sides of the upper connector 2.

[0028] The upper connector 2 has a metal plate 20 installed on its periphery. The metal plate 20 has a U-shaped structure. The upper connector 2 has a fixing groove for installing the metal plate 20. The elastic clamping plate 24 is set on both sides of the metal plate 20. The elastic clamping plate 24 and the metal plate 20 are integrally formed.

[0029] Furthermore, protrusions 22 are fixedly installed on both sides of the fixing groove, and locking holes 23 are provided on the metal plate 20 corresponding to the positions of the elastic locking plate 24. The protrusions 22 engage with the locking holes 23, and one end of the protrusions 22 is provided with a bevel that facilitates engagement with the locking holes 23. The metal plate 20 enters the fixing groove from the bevel side of the protrusions 22, and the protrusions 22 are fixed by engaging with the locking holes 23. The elastic locking plate 24 can fix the main body 1 by deformation.

[0030] Working Principle: In use, the upper connector 2 and lower connector 3 are first inserted into the upper plug terminal 7 and lower plug terminal 8 through the dual-position plug hole 6. Then, the fixing component and the limiting component are used to fix and limit the connection between the upper connector 2 and the upper plug terminal 7, and between the lower connector 3 and the lower plug terminal 8, ensuring the stability and reliability of the connection. The fixing component uses the snap-fit ​​plate 15 to fix the upper plug terminal 7 and the lower plug terminal 8, while the limiting component uses the outer limiting groove 17, the side limiting groove 18, and the inner limiting groove 19 to cooperate with the first limiting part 25, the second limiting part 21, and the third limiting part 5 to achieve limiting. Simultaneously, the lower connector 3 is rotatably connected to the fixing frame 4 through a rotating connection structure, allowing the lower connector 3 to rotate relative to the fixing frame 4, facilitating the user to switch the wiring between the upper connector 2 and the lower connector 3. During rotation, the limiting post 9 rotates within the mounting hole 11, and then cooperates with the slot 14 through the limiting block 10 to achieve rotational stability and reliability. This eliminates the need for disassembly and assembly of the upper and lower connector terminals 7 and 8, making it very convenient. The compression spring 12 provides the lower connector 3 with a certain degree of elasticity during rotation, further improving the stability and reliability of the connection.
