[0023] Initially, the connector 1 and the active connector 3 are separated from each other. When the first optical fiber 2 and the second optical fiber 10 need to be connected, the active connector 3 is inserted into the connector 1. When the active connector 3 is plugged in, the rotating component 61 positions the second plug-in board 5. At this time, multiple groups of second plug-in boards 5 and multiple groups of first plug-in boards 4 are staggered. After the active connector 3 is plugged into the surface of the connector 1, the rotating component 61 controls the multiple groups of second plug-in boards 5 to rotate synchronously by a certain angle, so that the second plug-in boards 5 and the first plug-in boards 4 are relatively distributed. At this time, the clamping component 62 controls the second plug-in board 5 and the first plug-in board 4 to be connected into a whole. At this time, the first plug-in board 4 and the second plug-in board 5 cooperate with each other, and the active connector 3 can be stably supported and positioned at the end of the connector 1, effectively preventing the active connector 3 from falling off the surface of the connector 1. After the second plug-in board 5 rotates to a position opposite to the first plug-in board 4, the automatic limit assembly 81 further fixes the position of the second plug-in board 5 on the surface of the active connector 3. At this time, the automatic limit assembly 81 cooperates with the rotation assembly 61 to further limit the second plug-in board 5 from rotating outside the first plug-in board 4. When the active connector 3 needs to be unplugged, the adjustment assembly 82 cooperates with the automatic limit assembly 81 to preliminarily release the restriction on the second plug-in board 5. The rotation assembly 61 controls the second plug-in board 5 to rotate outside the first plug-in board 4. At this time, the first plug-in board 4 is separated from the second plug-in board 5, and the active connector 3 can be easily unplugged.

[0024] like Figure 2 , Figure 3 , Figure 4 As shown, as a preferred embodiment of the present invention, the rotating component 61 includes an annular rotating groove 611 opened on the side wall of the connector 1, a load-bearing ring 612 is rotatably installed in the rotating groove 611, a second plug-in board 5 is fixedly installed on the surface of the load-bearing ring 612, a plurality of groups of second plug-in boards 5 are distributed in a ring shape with equal spacing, and a limiting portion 7 which cooperates with the load-bearing ring 612 is provided on the side wall of the connector 1.

[0025] When the position of the second plug-in board 5 needs to be adjusted, the load-bearing ring 612 is controlled to rotate at the side wall of the connector 1, and the load-bearing ring 612 drives the second plug-in board 5 to rotate synchronously. After the second plug-in board 5 rotates to a suitable position, the limiting portion 7 fixes the position of the load-bearing ring 612 at the side wall of the connector 1, thereby fixing the position of the second plug-in board 5.

[0026] like Figure 1 , Figure 3 , Figure 4As shown, as a preferred embodiment of the present invention, the snap-in assembly 62 includes a snap-in strip 621 fixedly installed on a side wall of the first plug-in board 4 facing the second plug-in board 5, the snap-in strip 621 is made of elastic material, and a snap-in groove 622 that cooperates with the snap-in strip 621 is provided on the side of the second plug-in board 5 facing the first plug-in board 4.

[0027] After the active connector 3 is inserted into the surface of the connector 1, the second plug-in board 5 is rotated to a position relative to the first plug-in board 4. At this time, the snap-in strip 621 on the surface of the first plug-in board 4 is inserted into the snap-in groove 622 on the surface of the second plug-in board 5. The snap-in strip 621 and the snap-in groove 622 cooperate with each other, so that the first plug-in board 4 and the second plug-in board 5 can be conveniently connected as a whole.

[0028] like Figure 1 , Figure 3 , Figure 4 As shown, as a preferred embodiment of the present invention, the limiting portion 7 includes two groups of parallel distributed limiting grooves 73 opened on the surface of the supporting ring 612, and the side wall of the connector 1 is rotatably installed with a limiting rod 71 that cooperates with the limiting groove 73, and the limiting rod 71 is made of magnetic material, and the side wall of the connector 1 is fixedly installed with a magnetic strip 72 that cooperates with the limiting rod 71.

[0029] Initially, the limiting rod 71 is inserted into a group of limiting grooves 73. At this time, the first plug-in board 4 and the second plug-in board 5 are staggered. After the active connector 3 is inserted into the surface of the connector 1, the limiting rod 71 is controlled to separate from the limiting groove 73. At this time, the load-bearing ring 612 can be conveniently controlled to rotate in the rotating groove 611. After the second plug-in board 5 rotates to a position relative to the first plug-in board 4, the limiting rod 71 is inserted into another group of limiting grooves 73, so that the position of the load-bearing ring 612 can be conveniently fixed.

[0031] Initially, the entirety of the latching post 814 is in the receiving groove 813. After the second plug-in board 5 is rotated to a position opposite to the first plug-in board 4, the latching groove 811 at the bottom end of the second plug-in board 5 is aligned with the receiving groove 813. The magnetic block 812 pulls the latching post 814 toward the outside of the receiving groove 813 through magnetic attraction. The latching post 814 is further inserted into the latching groove 811. The latching post 814 can further fix the position of the second plug-in board 5 on the outside of the active connector 3. When the active connector 3 needs to be pulled out, the adjusting assembly 82 first controls the latching post 814 to retract into the receiving groove 813. At this time, the latching post 814 releases the restriction on the second plug-in board 5.

[0032] like Figure 1 , Figure 3 , Figure 4 As shown, as a preferred embodiment of the present invention, the adjustment component 82 includes a control ring 821 which is sleeved on the surface of the movable connector 3, a sliding portion 9 connected to the control ring 821 is provided on the surface of the movable connector 3, a wire groove 822 connected to the receiving groove 813 is opened inwardly on the surface of the movable connector 3, and one end of the clamping column 814 located in the receiving groove 813 is fixedly connected with a control rope 823, and one end of the control rope 823 away from the clamping column 814 extends through the wire groove 822 to the outside of the movable connector 3 and is connected to the control ring 821.

[0033] When the movable connector 3 is to be pulled out, the control ring 821 is pushed on the surface of the movable connector 3 to move. The control ring 821 cooperates with the control rope 823 to pull the clamping column 814 into the storage groove 813. At this time, the second plug-in board 5 can be conveniently controlled to rotate outside the first plug-in board 4.

[0034] like Figure 1 , Figure 3 , Figure 4 As shown, as a preferred embodiment of the present invention, the sliding portion 9 includes a plurality of slide grooves 91 opened on the surface of the movable connector 3, a slider 92 is slidably installed in the slide groove 91, the slider 92 extends to the outside of the slide groove 91 and is connected to the control ring 821, and a return spring 93 is fixedly installed at one end of the slide groove 91 close to the first plug-in board 4, and the telescopic end of the return spring 93 is connected to the slider 92.

[0035] The slider 92 cooperates with the slide groove 91 to limit the control ring 821 from sliding along a specific track on the surface of the movable connector 3 , thereby adjusting the position of the control ring 821 .

[0036] The working principle of the present invention is as follows: initially, the connector 1 and the active connector 3 are separated from each other. When the first optical fiber 2 and the second optical fiber 10 need to be connected, the active connector 3 is inserted into the connector 1. When the active connector 3 is plugged in, the multiple groups of second plug-in boards 5 are staggered with the multiple groups of first plug-in boards 4. After the active connector 3 is plugged into the surface of the connector 1, the limiting rod 71 is controlled to separate from the limiting groove 73. At this time, the bearing ring 612 can be conveniently controlled to rotate in the rotating groove 611. After the second plug-in board 5 rotates to a position relative to the first plug-in board 4, the limiting rod 71 is inserted into another group of limiting grooves 73, and the position of the bearing ring 612 can be conveniently fixed. The clamping strip 621 on the surface of the first plug-in board 4 is inserted into the clamping groove 622 on the surface of the second plug-in board 5. The clamping strip 621 and the clamping groove 622 cooperate with each other, and the first plug-in board 4 and the second plug-in board 5 can be conveniently connected as a whole. At this time, the first plug board 4 and the second plug board 5 cooperate with each other, and the active connector 3 can be stably supported and positioned at the end of the connector 1, effectively preventing the active connector 3 from falling off the surface of the connector 1. After the second plug board 5 rotates to a position relative to the first plug board 4, the magnetic block 812 pulls the clamping column 814 to move to the outside of the storage groove 813 through magnetic attraction, and the clamping column 814 is further inserted into the clamping groove 811. The clamping column 814 can further fix the position of the second plug board 5 on the outside of the active connector 3. When the active connector 3 needs to be pulled out, the control ring 821 is pushed on the surface of the active connector 3 to move. The control ring 821 cooperates with the control rope 823 to pull the clamping column 814 into the storage groove 813. At this time, the second plug board 5 can be conveniently controlled to rotate outside the first plug board 4.
