[0060] The optical cross-connection device provided in this embodiment, when in use, is driven by a driving mechanism to drive the first connection block 8 to move in the first direction and the second connection block 20 to move in the second direction. When the first connection block 8 moves, it drives M moving blocks 10 to move simultaneously, and each moving block 10 drives N anti-slip plates 14 thereon to move simultaneously, so that the side of each anti-slip plate 14 abuts against the corresponding connection line, so that multiple external connection lines can be limited to prevent them from falling off; and a single anti-slip plate 14 can be moved and reset by an elastic pulling mechanism to achieve abutment or release of abutment against a single external connection line, so that this embodiment can limit or release the limit of multiple or single external connection lines.

When it is not connected, the shielding plate 23 shields the input interface 37 to prevent debris from entering and affecting the next use.

[0061] Alternatively, if Figure 4-Figure 7As shown, a first cavity 511 is provided in the first mounting portion 51, a second cavity 521 is provided in the second mounting portion 52, and an active cavity 53 is provided between the first cavity 511 and the second cavity 521. The driving mechanism includes a first screw rod 6, a second screw rod 19 and a transmission assembly. The first screw rod 6 extends along a first direction and is rotatably mounted in the first cavity 511, and the first connecting block 8 is threadedly sleeved on the first screw rod 6. Specifically, the first end of the first screw rod 6 passes through the active cavity 53 and extends outside the fixed block 5, and a knob 7 is installed on the first end of the first screw rod 6, and the second end of the first screw rod 6 is rotatably connected to the inner wall of the first cavity 511. In this embodiment, the first screw rod 6 can be driven to rotate by turning the knob 7, so that the first connecting block 8 moves along the first direction. The second screw rod 19 extends along the second direction and is rotatably mounted in the second cavity 521, and the second connecting block 20 is threadedly sleeved on the second screw rod 19. Specifically, the first end of the second screw rod 19 extends into the movable cavity 53, and the second end of the second screw rod 19 is rotatably connected to the inner wall of the second cavity 521. The transmission assembly is disposed in the movable cavity 53 and is transmission-connected between the first screw rod 6 and the second screw rod 19. When the first screw rod 6 rotates, it can drive the second screw rod 19 to rotate, thereby moving the second connecting block 20 along the second direction.

[0062] Optionally, the transmission assembly includes a first bevel gear 29 and a second bevel gear 30, the first bevel gear 29 is sleeved on the first screw rod 6, the second bevel gear 30 is sleeved on the second screw rod 19, and the first bevel gear 29 and the second bevel gear 30 are meshed. The above arrangement has a simple structure and reliable transmission, and the first screw rod 6 and the second screw rod 19 rotate simultaneously through the cooperation of the first bevel gear 29 and the second bevel gear 30.

[0063] Furthermore, a locking assembly is also provided in the active cavity 53 to limit the rotation of the first screw rod 6. Specifically, Figure 5As shown, the locking assembly includes a circular gear 31, a moving rod 32, a pulling plate 33, a moving plate 34 and a first elastic member 36, wherein the circular gear 31 is fixedly sleeved on the first screw rod 6; a moving hole is opened at the top of the fixed block 5, and the moving rod 32 is slidably installed in the moving hole, the first end of the moving rod 32 is located in the active cavity 53, and the second end of the moving rod 32 extends to the outside of the fixed block 5; the moving plate 34 is installed at the first end of the moving rod 32, and the bottom of the moving plate 34 is provided with a plurality of limiting tooth blocks 35 adapted to the circular gear 31; the pulling plate 33 is installed at the second end of the moving rod 32 for convenient hand-held operation; the first elastic member 36 is sleeved on the moving rod 32, one end of the first elastic member 36 is connected to the top of the moving plate 34, and the other end is connected to the inner wall of the active cavity 53, and the first elastic member 36 has a tendency to make the moving plate 34 press against the circular gear 31. When the first screw rod 6 needs to be rotated, the pull plate 33 is pulled upward to disengage the limit tooth block 35 from the circular gear 31; when the first screw rod 6 needs to be prevented from rotating, the pull plate 33 is released, and the first elastic member 36 enables the limit tooth block 35 to be engaged with the circular gear 31. The above arrangement facilitates the limiting of the first screw rod 6, and prevents the first screw rod 6 from rotating during use and affecting the anti-slip effect. Preferably, in this embodiment, the first elastic member 36 is a spring.

[0064] like Figure 8 As shown, the elastic pulling mechanism includes a pull rope 15, a limit rod 17, and a second elastic member 13. The first end of the pull rope 15 is fixed to the side of the slider 12, and a rope hole communicating with the moving cavity 101 is provided on the moving block 10, and the second end of the pull rope 15 passes through the rope hole and is installed with a pull ring 16; the limit rod 17 is provided on the moving block 10, and is used to hang the pull ring 16, and the free end of the limit rod 17 is installed with a limit plate 18; the first end of the second elastic member 13 is installed on the side of the slider 12, and the second end of the second elastic member 13 is installed on the inner side wall of the moving cavity 101, and the second elastic member 13 has a movement tendency to make the anti-slip plate 14 extend outward from the moving block 10. The above arrangement facilitates the movement of a single slider 12, so that a single connecting line can be limited or released; when the pull rope 15 is pulled, the elastic force of the second elastic member 13 can be overcome, so that the anti-drop plate 14 moves back into the moving block 10, and the limit on the connecting line is released; when the pull rope 15 is not subjected to force, the slider 12 and the anti-drop plate 14 are reset under the action of the second elastic member 13, and the connecting line can be limited and prevented from dropping. Preferably, in this embodiment, the second elastic member 13 is a spring.

[0065] Furthermore, in this embodiment, a cleaning pad is installed on one side of each shielding plate 23 opposite to the input interface 37. The cleaning pad is provided to facilitate wiping the input interface 37 when the shielding plate 23 is reset, so as to avoid adhesion of debris and affect the next use.

[0066] Furthermore, a groove 201 is provided in the second connection block 20, and two fixed rods 21 extending along the third direction are installed on the inner wall of the groove 201. The movable block 22 is slidably sleeved on the two fixed rods 21, so that the movable block 22 can slide along the third direction. N shielding plates 23 are respectively fixedly connected to the movable block 22. When the second connection block 20 moves along the second direction, it can drive the movable block 22 and each shielding plate 23 to move along the second direction at the same time. In this embodiment, the third direction is perpendicular to the first direction and the second direction, and is specifically the front-to-back direction of the connecting device body 1.

[0067] The optical cross-connection device of this embodiment also includes a scraping assembly, which specifically includes an extrusion plate 25, a trapezoidal block 26, an elastic reset assembly, a connecting plate 27 and a scraper 28. The extrusion plate 25 is fixed to the side of the movable block 22.

The elastic reset assembly is provided between the side of the movable block 22 and the side wall of the groove 201, and is used to reset the movable block 22 forward. N connecting plates 27 are fixed to the side of the second mounting portion 52, and a scraper 28 is fixed to each connecting plate 27. The scraper 28 is located at the lower rear side of the corresponding shielding plate 23. When the movable block 22 drives the squeeze plate 25 to move downward and contact the inclined surface of the trapezoidal block 26, the trapezoidal block 26 cooperates with the squeeze plate 25 to enable the movable block 22 to move backward and downward, that is, each shielding plate 23 moves backward and downward at the same time; when the squeeze plate 25 contacts the vertical surface of the trapezoidal block 26, each shielding plate 23 contacts the corresponding scraper 28, and at this time, each shielding plate 23 continues to move downward, which will cause the scraper 28 to scrape off the debris on the cleaning pad of the shielding plate 23. The above arrangement realizes the cleaning of the cleaning pad surface of each shielding plate 23, thereby reducing the residual debris. At the same time, the scraper 28 can cover the side of the shielding plate 23 with the cleaning pad to prevent the shielding plate 23 from being contaminated with debris during use.

[0068] Optionally, the elastic reset assembly includes two third elastic members 24, the two third elastic members 24 are respectively sleeved on the two fixed rods 21, one end of the third elastic member 24 is connected to the side of the movable block 22, and the other end is connected to the inner wall of the groove 201, and the third elastic member 24 has a tendency to make the movable block 22 move toward the front side of the connecting device body 1. Through the arrangement of the third elastic member 24, when the extrusion plate 25 is not in contact with the trapezoidal block 26, the movable block 22 can be reset forward under the action of the third elastic member 24. Preferably, in this embodiment, the third elastic member 24 is a spring.

[0069] This embodiment also provides a method for using an optical cross-connect device, which specifically includes the following steps:

[0070] S1. When in use, first place the connecting device body 1 at the designated position, and then turn the knob 7. The rotation of the knob 7 will cause the first screw rod 6 to rotate, and the rotation of the first screw rod 6 will cause the first connecting block 8 to move in the first direction. The movement of the first connecting block 8 will cause the M fixed plates 9 to move, and the movement of the M fixed plates 9 will cause the M moving blocks 10 to move, wherein each moving block 10 drives the N anti-slip plates 14 to move; at the same time, the rotation of the first screw rod 6 will cause the first bevel gear 29 to rotate, and the rotation of the first bevel gear 29 will cause the second bevel gear 30 to rotate, and the rotation of the second bevel gear 30 will cause the second screw rod 19 to rotate, and the rotation of the second screw rod 19 will cause the second connecting block 20 to move in the second direction, and the movement of the second connecting block 20 will drive the N shielding plates 23 to move; when the side of each anti-slip plate 14 corresponds to each input interface 37, the shielding plate 23 cancels the protection of the input interface 37, and the external connecting line is inserted into the input interface 37 at this time;

[0071] S2. After the connecting wire is inserted, the knob 7 is continuously rotated. The first connecting block 8 is continuously moved.

[0072] S3. When plugging or unplugging a single connection line, pull the pull ring 16, and limit the pull ring 16 through the limit rod 17 and the limit plate 18. When the pull ring 16 drives the pull rope 15 to move, the pull rope 15 drives the slider 12 to move along the first direction. The movement of the slider 12 will retract the anti-drop plate 14, thereby releasing the limit on the connection line, and then the single connection line is plugged or unplugged; when the plugging or unplugging is completed, the limit on the pull ring 16 is released, and the slider 12 is reset under the action of the second elastic member 13, thereby resetting the anti-drop plate 14; therefore, this embodiment can limit or release the limit on multiple or single connection lines when in use, and the shielding plate 23 can be used to shield and wipe the input interface 37 when not connected to prevent debris from entering and affecting the next use;

[0073] S4, after the connection line is plugged in, the connection operation is performed through the optical cross-connection matrix 2, the management controller 3 and the display 4;

[0074] S5. At the same time, when the knob 7 is continuously rotated in S2, the second connecting block 20 will continue to move. The continued movement of the second connecting block 20 will cause the squeezing plate 25 to be squeezed by the trapezoidal block 26 and move backward and downward. The backward and downward movement of the squeezing plate 25 will cause the movable block 22 to move backward and downward. The backward and downward movement of the movable block 22 will cause the shielding plate 23 to move backward and downward. When the squeezing plate 25 contacts the vertical surface of the trapezoidal block 26, the shielding plate 23 contacts the scraper 28. At this time, the shielding plate 23 continues to move downward, causing the scraper 28 to clean the surface of the cleaning pad, thereby reducing the residual debris. At the same time, the scraper 28 can cover the side of the shielding plate 23 with the cleaning pad to avoid the shielding plate 23 being contaminated with debris during use.

[0075] S6. When the first screw rod 6 needs to rotate, the moving rod 32 is pulled out by the pulling plate 33, so that the moving plate 34 avoids the circular gear 31; when the first screw rod 6 does not need to rotate, the moving plate 34 is reset under the action of the first elastic member 36, and the limiting tooth block 35 at the bottom of the moving plate 34 limits the circular gear 31, thereby limiting the first screw rod 6 to avoid the first screw rod 6 rotating during use and affecting the anti-slip effect.
