Moreover, the second connecting block 20 moves to drive the N shielding plates 23 to move simultaneously, which can avoid the shielding plates 23 when the connecting lines are inserted into the input interfaces 37, and the shielding plates 23 shield the input interfaces 37 when not connected, so as to avoid sundries from entering and affecting the next use.

[0061] Optionally, as shown in Figures 4-7As shown, the first mounting portion 51 is provided with a first cavity 511, the second mounting portion 52 is provided with a second cavity 521, and the first cavity 511 and the second cavity 521 are provided with a movable cavity 53. The driving mechanism comprises a first screw rod 6, a second screw rod 19 and a transmission assembly. The first screw rod 6 extends in a first direction and is rotatably arranged in the first cavity 511, and a first connecting block 8 is threadedly sleeved on the first screw rod 6. Specifically, a first end of the first screw rod 6 extends out of the fixed block 5 through the movable cavity 53 and is provided with a knob 7, and a second end of the first screw rod 6 is rotatably connected to an inner wall of the first cavity 511. In this embodiment, the knob 7 can be twisted to drive the first screw rod 6 to rotate, so that the first connecting block 8 moves in the first direction. The second screw rod 19 extends in a second direction and is rotatably arranged in the second cavity 521, and a second connecting block 20 is threadedly sleeved on the second screw rod 19. Specifically, a first end of the second screw rod 19 extends into the movable cavity 53, and a second end of the second screw rod 19 is rotatably connected to an inner wall of the second cavity 521. The transmission assembly is arranged in the movable cavity 53 and is in transmission connection between the first screw rod 6 and the second screw rod 19, so that the first screw rod 6 can drive the second screw rod 19 to rotate when the first screw rod 6 rotates, so that the second connecting block 20 moves in the second direction.

[0062] Optionally, the transmission assembly comprises 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 in engagement. The above-mentioned structure is simple and reliable in transmission, and the first screw rod 6 and the second screw rod 19 are simultaneously rotated through the cooperation of the first bevel gear 29 and the second bevel gear 30.

[0063] Further, the movable cavity 53 is further provided with a locking assembly for limiting rotation of the first screw rod 6. Specifically, as shown in Figure 5As shown, the locking assembly includes a spur gear 31, a moving rod 32, a pull plate 33, a moving plate 34, and a first elastic element 36. The spur gear 31 is fixedly sleeved on the first lead screw 6. A moving hole is provided on 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 movable 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 on the first end of the moving rod 32, and the bottom of the moving plate 34 is provided with a plurality of limiting teeth 35 that are adapted to the spur gear 31. The pull plate 33 is installed on the second end of the moving rod 32 for easy hand operation. The first elastic element 36 is sleeved on the moving rod 32. One end of the first elastic element 36 is connected to the top of the moving plate 34, and the other end is connected to the inner wall of the movable cavity 53. The first elastic element 36 has a tendency to make the moving plate 34 press against the spur gear 31. When the first lead screw 6 needs to be rotated, the pull plate 33 is pulled upwards to disengage the limiting tooth block 35 from the sprocket 31; when it is necessary to prevent the first lead screw 6 from rotating, the pull plate 33 is released, and the first elastic element 36 engages the limiting tooth block 35 with the sprocket 31. This configuration facilitates limiting the first lead screw 6, preventing it from rotating during use and affecting the anti-disengagement effect. Preferably, in this embodiment, the first elastic element 36 is a spring.

[0064] like Figure 8 As shown, the elastic pulling mechanism includes a pull rope 15, a limiting rod 17, and a second elastic element 13. The first end of the pull rope 15 is fixed to the side of the slider 12. A rope hole communicating with the moving cavity 101 is provided on the moving block 10. The second end of the pull rope 15 passes through the rope hole and is fitted with a pull ring 16. The limiting rod 17 is disposed on the moving block 10 and is used to hook the pull ring 16. A limiting plate 18 is installed on the free end of the limiting rod 17. The first end of the second elastic element 13 is installed on the side of the slider 12, and the second end of the second elastic element 13 is installed on the inner side wall of the moving cavity 101. The second elastic element 13 has a tendency to cause the anti-detachment plate 14 to extend outward from the moving block 10. The above configuration facilitates the movement of a single slider 12, thereby limiting or releasing the restriction on a single connecting line. When the pull rope 15 is pulled, it overcomes the elastic force of the second elastic element 13, causing the anti-detachment plate 14 to retract into the moving block 10, releasing the restriction on the connecting line. When the pull rope 15 is not under force, the slider 12 and the anti-detachment plate 14 return to their original positions under the action of the second elastic element 13, thus limiting and preventing the connecting line from detaching. Preferably, in this embodiment, the second elastic element 13 is a spring.

[0065] Furthermore, in this embodiment, a cleaning pad is installed on the side of each shield 23 opposite to the input interface 37. The cleaning pad facilitates wiping the input interface 37 when the shield 23 is reset, preventing debris from sticking and affecting the next use.

[0066] Further, the second connecting block 20 is provided with a groove 201, and the inner wall of the groove 201 is provided with two fixed rods 21 extending in the third direction, and the movable block 22 is sleeved on the two fixed rods 21, so that the movable block 22 can slide in the third direction. N shielding plates 23 are fixedly connected to the movable block 22 respectively, and when the second connecting block 20 moves in the second direction, the movable block 22 and the shielding plates 23 can be driven to move in the second direction simultaneously. In the embodiment, the third direction is perpendicular to the first direction and the second direction, and specifically, the third direction is perpendicular to the front-to-back direction of the connecting device body 1.

[0067] The optical cross-connect device further comprises a scraping assembly, which specifically comprises a pressing plate 25, a trapezoidal block 26, an elastic reset assembly, a connecting plate 27 and a scraping plate 28. The pressing plate 25 is fixed to the side of the movable block 22. The trapezoidal block 26 is fixed to the side of the second mounting portion 52 and is used in cooperation with the pressing plate 25. The top of the trapezoidal block 26 is provided with an inclined surface inclined backward and downward, and the rear side of the trapezoidal block 26 is provided with a vertical surface. The elastic reset assembly is arranged 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 each connecting plate 27 is fixed with a scraping plate 28, which is located below and at the rear side of the corresponding shielding plate 23. When the movable block 22 drives the pressing plate 25 to move downward and contact the inclined surface of the trapezoidal block 26, the trapezoidal block 26 cooperates with the pressing plate 25 to move the movable block 22 backward and downward, i.e., the shielding plates 23 move backward and downward simultaneously. When the pressing plate 25 contacts the vertical surface of the trapezoidal block 26, the shielding plates 23 contact the corresponding scraping plates 28. At this time, if the shielding plates 23 continue to move downward, the scraping plates 28 can scrape the sundries on the cleaning pads of the shielding plates 23. The above arrangement realizes the cleaning of the surface of the cleaning pad of each shielding plate 23, thereby reducing the sundry residues, and the scraping plate 28 can shield the side of the shielding plate 23 with the cleaning pad, thereby avoiding the contamination of the shielding plate 23 during use.

[0068] Optionally, the elastic reset assembly comprises two third elastic members 24, which are sleeved on the two fixed rods 21 respectively. 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. The third elastic member 24 has a tendency to move the movable block 22 to the front side of the connecting device body 1. Through the arrangement of the third elastic member 24, when the pressing plate 25 does not contact the trapezoidal block 26, the movable block 22 can be reset forward under the action of the third elastic member 24. Preferably, in the embodiment, the third elastic member 24 is a spring.
